Closes #249

Parent: https://github.com/DIG-Network/dig_ecosystem/issues/2790 (NC-12, gap 2)


Direct answers to the three questions

1. Coinset is DEMOTED TO A REGISTERED DISCOVERY SOURCE. It is neither the peak's source nor its
corroborator, and it is not removed.

  • For the peak, coinset is out of the path entirely. When peer reads are attached — every
    production transport — ChainTransport::peak_height never calls chia-query's router, so
    router.rs:711-717's coinset-first get_blockchain_state is never reached for this read.
  • It is not a corroborator either, deliberately. Letting one HTTPS endpoint break a tie among
    untrusted peers would let it decide the number at exactly the moment corroboration failed — the
    single-source dependency in its most dangerous form, not its mildest.
  • It stays registered as a PublicOracle in its own independence group, at a priority BEHIND
    this node's peers, so non-custody discovery reads can still use it and the operator can still see
    and reach it. Deleting it would remove a source the registry exists to name.
  • chia-query itself is not modified. Inverting router.rs there is a cross-repo release-first
    cascade; the node-side fix needs no release.

What the node reports when peers disagree: NO HEIGHT. control.wallet.peak answers
peak_height: null, which the SPEC already defines as UNKNOWN and forbids reading as height zero.
No repaired value, no plurality-wins arm, no fallback. The same applies to a sample that has
collapsed to one voice. The height when they DO agree is min(credible claims) − SETTLED_LAG over
claims within PEAK_LAG_TOLERANCE of the median — so it can lag the true tip and can never lead
it, which is the safe direction for every confirmation comparison built on it.

2. Yes — and the proof is that a path building its own fabric turns something RED, not that a
registry exists.

sole_owner_tests::only_the_registry_owner_constructs_a_peer_fabric sweeps every production
call site of ChiaQuery::new in the crate and fails on any outside sources.rs. It was RED
when written, naming ["chain.rs:131"] — the exact path that falsified the clause. Add a second
fabric anywhere in dig-wallet today and that test fails by name and line.

Two guards against the vacuity this ticket is about:

  • a control (the_sweep_can_find_a_construction_site_at_all) fails if the sweep finds zero
    ChiaQuery::new anywhere, so a broken file walk or a renamed constructor cannot make it pass by
    measuring nothing;
  • the test file is excluded from its own haystack, so the sweep cannot match its own needle.

What it catches that today's code would not: an ornamental registry — constructed, never
consulted — satisfies NC-12's wording exactly as vacuously as no registry at all. That is what
custody_fails_closed_tests pins: the custody view must refuse with the variant
ChainSourceError::NoProvider, while the discovery view must not be NoProvider. The pair
separates "populated registry that refuses custody" from "empty registry" — and from "registry
that would happily accept the oracle for custody and merely could not reach it"
, which any
is_err() assertion would have passed.

This is deliberately the dig-node#356 standard: not a doc comment asserting the property, but a
one-line violation that turns a test red. The peak half meets the same bar — reverting only the
placement fails all three transport tests by their placement message.

3. #351 does NOT block this, and this change does not depend on the number it mis-reports.

chia_peer_count comes from chia_query::ChiaQuery::peer_count() — the fabric's pool size, on a
different accessor and a different path from anything here. Nothing in this change reads it.

The distinction that matters: the corroborated peak counts claims actually received in this
round
, one per peer that answered, not a reported pool size. So a count stuck at 5 while the node
holds zero cannot inflate the plurality — a node in that state receives no claims, and
settled_peak returns None. three_silent_peers_leave_one_voice_and_that_is_not_agreement is
exactly that case pinned as a test: four peers drawn, one speaking, refusal.

#351 remains a real defect on its own surface, and its wider point stands — it is why the plurality
here is evidenced by received claims rather than by any reported count.


The problem, stated precisely

NC-12's third acceptance clause reads "no path constructs its own peer fabric outside the
registry"
. It held because there was no registry. chia_query::provider_registry::ProviderRegistry
had no production construction site anywhere in dig-node — before PR #339 or after — so the clause
was satisfied by the absence of the thing it governs. A clause that passes because its subject does
not exist is not a property, and it must not read as discharged.

Second, and separately: the node's headline chain fact was a third party's notion. chia-query's
router.rs:711 get_blockchain_state tries api.coinset.org FIRST and consults this node's own
peers only when that fails, so ChainTransport::peak_height returned one HTTPS endpoint's view of
the chain even on a node holding five peers — and that number divides into the confirmation counts
served over RPC.

The shape, and why

Unify the OWNER, keep the VOICES.

1. dig_wallet::sage::sources::NodeChainSources is now the only production caller of
ChiaQuery::new in dig-wallet, and it registers what it built:

provider kind independence group priority
this node's dialled Chia peers DigPeers (→ untrusted) chia-peers 5
coinset.org PublicOracle (→ untrusted) coinset.org chia-query's own

allow_public_quorum_custody is left off, so the custody view fails closed on a default
install: no public oracle and no randomly dialled peer may decide where money goes merely by
answering first. ChainTransport holds the sources and reads through them.

The registry is built per call rather than heldProviderRegistry composes
dyn ChainSourceProvider, which chia-query does not bound Send + Sync (its providers are a
blocking facade by design), so a field would make NodeChainSources non-Sync and infect every
async caller. Building it boxes two wrappers around the fabric that already exists and dials nothing.

2. ChainTransport::peak_height stops going through the router. It asks the peers this node
dialled itself, concurrently, and settles them with a new quorum::settled_peak.

The reported height is min(credible claims) − SETTLED_LAG, over claims within PEAK_LAG_TOLERANCE
of the median (a median cannot be moved by one outlier; a maximum can, and is the single most
attacker-friendly aggregate available). Quorum floor is CORROBORATION_FLOOR claimants; a band
failing band_kept_a_majority is a split. On a split, or a collapse to one voice, the node reports
no height
— never a repaired number and never a fallback to the oracle, because falling through
would let one endpoint overrule the peers at exactly the moment corroboration failed.

It is deliberately not the tip. It is a height every credible peer has passed, so it can lag by
a few blocks and can never lead — the safe direction for every "is this coin buried yet" comparison
built on it. Stated as such in the doc comment and in SPEC §control.wallet.peak.

3. ChiaCoinPeer now HOLDS its session's inbound stream instead of dropping it, so each peer's
claimed tip stays current across the 5-minute sample lifetime rather than being frozen at handshake.
await_peak is refactored into await_peak_from + peak_from so the corroborator and the held
sample share ONE parser — a second parser of the same message would be free to disagree with this
one about what a peer claimed.

What this does NOT do

  • ChiaQuorumCorroborator and DialedPeerSample are untouched and NOT collapsed. They dial
    independently on purpose; one dialler is the goal, one voice is a regression.
  • chia-query is not modified. Inverting router.rs there is a cross-repo release-first
    cascade; the node-side fix needs no release, so the ordering is settled here.
  • No trusted flag is set on any dialled peer. That maps to a custody grant, and this change
    gets nowhere near it.

Blast radius checked

gitnexus has no index for this worktree, so blast radius was taken by grep + direct read, as §2.0
permits and requires me to say.

  • ChiaQuery::new — 3 sites in dig-wallet, 1 production (chain.rs:131, relocated) and 2
    #[cfg(test)]. Zero elsewhere in the workspace.
  • ChainTransport::peak_height / ChainFallback::peak_height — one production consumer,
    sage/rpc.rs:1916, the control.wallet.peak fallback arm. Its stale "outbound call to the
    third-party tier" comment is corrected in the same diff.
  • await_peak — one caller (sync_supervisor.rs:1979), preserved as a wrapper.
  • ChainTransport.client field — private; 3 test reads, migrated to existing_client().
  • CoinPeer — 2 implementors (ChiaCoinPeer, the test ScriptedPeer), both updated.
  • Risk: MEDIUM, not high. The one user-visible behaviour change is that
    control.wallet.peak's fallback arm now answers peak_height: null where peers disagree instead
    of a coinset number. That is the honest direction and the one this ticket asks for; the replica
    arm, which serves most reads, is untouched.

Evidence

cargo test --workspace --no-fail-fast: 0 failed in every target; dig-wallet lib 625 passed
(now 636 with the new tests). cargo clippy --workspace --all-targets clean. Passed-counts read
from the test result: lines, not from a bare ok.

The property is proven, not asserted

  • sole_owner_tests::only_the_registry_owner_constructs_a_peer_fabric sweeps every production
    ChiaQuery::new site and fails on any outside sources.rs. It was RED when written, naming
    ["chain.rs:131"]. It ships with a controlthe_sweep_can_find_a_construction_site_at_all
    — because a sweep over a broken file walk or a renamed constructor reports clean while measuring
    nothing.
  • custody_fails_closed_tests shows the registry DECIDES something. The custody refusal asserts
    the variant ChainSourceError::NoProvider, not merely that it failed: an unreachable network
    also errors, so a test satisfied by any error would pass against a registry that accepted the
    oracle for custody and simply could not reach it. The paired assertion — discovery is not
    NoProvider — is what separates "populated registry that refuses custody" from "empty registry",
    and it holds identically with a network or without one, so it needs neither.

Plurality is proven behaviourally

a_single_peer_yields_no_height_and_no_fallback_to_the_oracle (collapse to one → refusal),
three_silent_peers_leave_one_voice_and_that_is_not_agreement (four DRAWN, one speaking — the case
a draw-size check misses), a_lying_peer_does_not_move_the_peak_the_node_reports (asserts equality
with the liar-free answer, since "a height came back" is produced identically by a max-of-claims
implementation), plus controls at both layers so no refusal is satisfied by a function that
always refuses.

Revert-proof — and it caught a false green in my own tests

Reverting only the peak placement first made all three transport tests fail on their value
assertion, so the assertion pinning the oracle out of the path was never evaluated and proved
nothing. Reordered to assert placement first, the same revert fails each test by its own placement
message
. Recorded in the test module docs so it is not re-introduced.

What today's code would pass that these tests catch

A peak_height that reads the oracle first passes every value assertion whenever the oracle is
reachable and agrees — which is the normal case, and is why this went unnoticed. The placement
assertions catch it because they observe that no chain client was ever built. Likewise, an
ornamental registry constructed and never consulted satisfies NC-12's wording exactly as vacuously
as no registry at all; the custody-variant assertion catches that.

Known gaps, deliberately left (§2.6 — logged, not fixed here)

  • dig-node#351 (chia_peer_count is not a live measurement) is real and does not block this.
    It reads ChiaQuery::peer_count(), a different accessor on a different path; nothing here consults
    it, and the corroborated peak counts claims actually received this round rather than a reported
    pool size, so a stale count cannot inflate the plurality this change relies on.
  • §2.4b dep bumps are split out, not skipped. dig-wallet is behind on chia-query
    (0.6.2 → 0.16.0), dig-node-control-interface (0.19 → 0.21), dig-offers (0.2 → 0.3) and
    dig-clvm (0.2 → 0.3) — all semver-incompatible 0.x steps, and the chia-query one almost
    certainly carries the chia 0.36 line that dig-node#308 records as not currently attemptable. They
    dwarf this change; smuggling them in would make this diff unreviewable.

Version

Workspace 0.151.10.152.0, dig-wallet 0.34.00.35.0. Minor: a compatible new capability,
with one behaviour change a caller can only observe as an honest unknown where it previously
received a third party's number. No API was removed or renamed.

Rebase note (the bump had to be redone twice)

Branched at 90ed299. main then took #344 (015b1c6, 0.151.0 / dig-wallet 0.34.0) and
#353 (dffb264, 0.151.1). The first rebase silently absorbed this branch's bump with no
conflict
, because #344 had written the exact same values this branch had — both sides wrote
something plausible, so there was nothing for git to flag. The version-increment gate caught it, not
a reviewer. Re-bumped past main to 0.152.0 / 0.35.0.

Release hazard

dig-node's cron cuts a stable tag at midnight UTC unattended, so this merge gate is the last line
of defence. Do not merge until the gate round has returned.

SECURITY FINDING 1 — gap 2's guard is bypassable by the exact regression it names

Audited head: 41577001bd05194d1ef7f5ebdb01baeb36b8c441
Severity: HIGH (guard vacuity — not a live exploit; the deliverable does not hold)
Where: crates/dig-wallet/src/sage/sources.rs:212-224 (production_call_sites)

The defect

production_call_sites classifies a call site as test-code with a latch:

let mut in_tests = false;
for (ix, line) in text.lines().enumerate() {
    if line.contains("#[cfg(test)]") { in_tests = true; }
    if !in_tests && line.contains(CONSTRUCTOR) { sites.push(...); }
}

The latch is set by the first #[cfg(test)] anywhere in the file and is never cleared, so every
line below it is treated as test code — including a #[cfg(test)] on a single item inside an impl.

crates/dig-wallet/src/sage/chain.rs has its first #[cfg(test)] at line 157, on the with_client
test helper inside impl ChainTransport. The file is 711 lines. Lines 158-711 of chain.rs are
invisible to the sweep
, and that region contains peak_height(), peer_tier(), push(), the
ChainFallback impl and decode_signed_bundle — i.e. essentially the whole production surface of the
very file this PR moved the fabric out of.

The doc comment states the opposite as its safety argument:

"a deliberately conservative one: it can only ever over-report a test site as production, which fails
loudly, never under-report a production site as a test one, which would be the silent direction."

That claim is false for chain.rs, and chain.rs is the single most likely home of the regression.

Measured, not reasoned

I replicated production_call_sites exactly (same walk, same latch, same CONSTRUCTOR) and ran it in my
own worktree at this head.

Baseline:

haystack total matches: 5
production sites: ['sources.rs:116']
strays: []
VERDICT: PASS

Then I applied the regression the guard exists to catch — a second, unregistered peer fabric built
inside ChainTransport::peak_height itself:

MUTATION APPLIED: yes
198:        let _rogue = chia_query::ChiaQuery::new(chia_query::ChiaQueryConfig::default()).await;
haystack total matches: 6
production sites: ['sources.rs:116']
strays: []
VERDICT: PASS (strays empty and len==1)

Both assertions still pass with a live second fabric in the transport. strays is empty, and
sites.len() == 1 holds because the stray was never counted. The control test
(the_sweep_can_find_a_construction_site_at_all) also still passes — the haystack went 5 -> 6, so the
control cannot see this class of miss either: it proves the walk reads files, not that the walk
classifies them.

Exploit scenario

State: this PR merges; NC-12 clause 3 is recorded as a machine-enforced property.
Action: any later change re-adds a ChiaQuery::new inside ChainTransport below line 157 — the natural
place, since that is where the fabric used to live and where client() is still called from.
Impact: the node holds a second peer fabric the ProviderRegistry never names, outside the operator's
provider configuration and outside the independence-group accounting the custody quorum depends on, and
the guard reports green. The clause returns to being satisfied for a reason nobody can see — which is
precisely the vacuity this ticket was opened to remove.

Cheap fix

Latch only on a module-level #[cfg(test)] (attribute at column 0):

if line.starts_with("#[cfg(test)]") { in_tests = true; }

In chain.rs the top-level #[cfg(test)] markers are at 432 and 573, so this restores coverage of
lines 1-431 — including all of impl ChainTransport. It makes the doc comment's stated conservatism
true rather than aspirational. A regression test is available for free: assert that a fixture string
containing an indented #[cfg(test)] followed by a constructor is still reported.

Second, smaller scope hole (same finding, lower rank)

The walk covers env!("CARGO_MANIFEST_DIR")/srcdig-wallet only. A fabric constructed in
dig-node-core, dig-runtime or a bin target is invisible to it. No such site exists today (I grepped
ChiaQuery::new( and chia_query:: repo-wide at this head; every hit is in dig-wallet), so this is
latent, not live. Worth one sentence in the doc comment so the guard's scope is not overstated.

Finding 1 — cargo confirmation (not just the replication)

Ran the real test, in my own worktree at 41577001, with the rogue fabric compiled into
ChainTransport::peak_height:

=== mutation still applied? ===
1
   Compiling dig-wallet v0.35.0 (C:\tmp\worktrees\sec-354\crates\dig-wallet)

test sage::sources::sole_owner_tests::only_the_registry_owner_constructs_a_peer_fabric ... ok

test result: ok. 2 passed; 0 failed; 0 ignored; 0 measured; 645 filtered out

The crate compiled with the second fabric — so this is production code, not a fixture — and both the
guard and its control reported green. Parsed from the test result: line, passed-counts read rather than
the ok word. chain.rs has been restored in my worktree; the shared checkout and the lane's worktree
were never touched.

SECURITY FINDING 2 — the two "independence groups" are not independent: BOTH answer from api.coinset.org

Audited head: 41577001bd05194d1ef7f5ebdb01baeb36b8c441
Severity: HIGH (false trust classification; not live today, one line from live)
Where: crates/dig-wallet/src/sage/sources.rs:161-183 (NodeChainSources::registry), and the module
docs at sources.rs:19-25 and sources.rs:38-44

The defect

The registry registers two providers in two independence groups:

  • ChiaQueryProvider::new(client, ...) in group "chia-peers", priority 5
  • CoinsetProvider::from_env() in group "coinset.org"

chia-query defines an independence group as "sources that could fail or lie together — e.g. two views
of the same coinset.org — share a group id"
(provider_registry/registry.rs:98-100). These two share
an upstream, so by chia-query's own definition they belong in one group, not two.

The chain, in chia-query 0.6.2:

  • ChiaQueryProvider::peak_height -> self.inner.peak_height_opt()
    (provider_registry/chia_query_provider.rs:124-126)
  • ChiaQuery::peak_height_opt -> self.get_blockchain_state() (router.rs:364-367)
  • get_blockchain_state (router.rs:711-717):
pub async fn get_blockchain_state(&self) -> Result<BlockchainState, ChiaQueryError> {
    // Try coinset first for full state.
    if self.coinset_fallback_enabled {
        if let Ok(state) = self.coinset.get_blockchain_state().await {
            return Ok(state);
        }
    }
    // Fallback: return a minimal state from the peer-tracked peak.
  • ChiaQueryConfig::default() sets coinset_fallback_enabled: true (lib.rs:118), and
    NodeChainSources::client() (sources.rs:116) builds with exactly ChiaQueryConfig::default().

So the provider registered as this node's peers asks api.coinset.org first and consults peers only
when that fails. Both groups resolve to the same third party.

Measured

I enabled the operator opt-in the module docs describe, as a one-line mutation in my own worktree:

MUTATION APPLIED: yes -- allow_public_quorum_custody(true)
180:            .allow_public_quorum_custody(true)

and ran the custody test against the fixture's max_peers: 0 client — a client holding zero peers:

thread '...the_custody_view_refuses_because_nothing_is_trusted_not_because_nothing_answered'
panicked at crates\dig-wallet\src\sage\sources.rs:350:14:
a default install has no operator-trusted source, so custody must refuse: Some(9198108)

test result: FAILED. 1 passed; 1 failed; 0 ignored; 0 measured; 645 filtered out

custody_read reached quorum_read with PUBLIC_QUORUM_THRESHOLD = 2, and two distinct
independence groups agreed
— on a node holding no peers at all. The only source that could have
answered either group is coinset. That is the proof: one HTTPS endpoint satisfied a 2-of-2
independent-group custody quorum by itself.

Exploit scenario

State: this PR merges. An operator (or a later lane) reads sources.rs:19-25, which frames
allow_public_quorum_custody as the opt-in that unlocks the custody view, and turns it on — a
one-line, entirely reasonable-looking change, since the registry appears to hold two independent
sources and chia-query requires two.
Action: api.coinset.org (or anyone who can answer as it: a BGP/DNS position, a TLS-terminating
middlebox, a compromised endpoint) returns a false coin record or peak.
Impact: it is counted twice, once per group, satisfies the quorum by itself, and the custody view —
the money-routing view — returns it as corroborated. The node believes a single third party about where
funds are, with the registry reporting that two independent sources agreed. NC-12's single-source
dependency is not removed; it is disguised.

Two doc claims that are false as written

sources.rs:38-44:

"The registry's discovery view inverts that: the node's own peers answer, and the oracle is what is
left when they cannot."

It does not invert it. priority orders the two registrations; it cannot reorder what happens
inside the first registration, and the first registration is itself coinset-first. On a node holding
five peers, registry.any().peak_height() still returns coinset's number.

sources.rs:19-25:

"which independence group each belongs to"

The classification asserted here is not the one the code produces.

Why it is not live at this head

Two things hold it back, both of which should be stated rather than relied on:

  1. allow_public_quorum_custody is left OFF, so custody_read returns Err(NoProvider) at
    registry.rs:175-177 before any provider is queried. The custody view genuinely fails closed
    today (question 2's second half: yes, it is a hard exclusion, not a deprioritisation).
  2. NodeChainSources::registry() has no production consumer. I grepped .registry() repo-wide at
    this head: the only callers are sources.rs:341 and sources.rs:368, both tests. No production read
    path goes through trusted() or any().

Point 2 is worth sitting with, because the module doc says "A path that wants chain data asks it" and
none does. ChainTransport holds NodeChainSources and calls .client(), never .registry(). The
registry's enumeration and classification are real objects, but nothing production consults them — which
is close to the "ornamental registry" the doc says it is not. The PR's genuine, load-bearing security win
is the peak path (peer_reads::peak_height replacing the oracle-first router read); that half is on
the production path and it holds.

Recommended remedy

Pick one, and say which:

  • Register the two in the SAME independence group ("coinset.org") while the peer provider is a
    coinset-first router. Honest, one line, and it makes a future allow_public_quorum_custody(true)
    fail closed instead of silently self-corroborating.
  • Or build the registered peer provider from a client with coinset_fallback_enabled: false, so the
    "chia-peers" group really is peers-only, and the group names become true. Note this is a different
    ChiaQuery from the one client() hands out, which the module deliberately avoids — so this needs a
    design call, not a patch.

Either way the two doc claims above need to match the code.

SECURITY FINDING 3 — "it never leads it" is false, and the peak path does not inherit the 6-of-10 analysis

Audited head: 41577001bd05194d1ef7f5ebdb01baeb36b8c441
Severity: MEDIUM (overstated security claim on the read that decides whether money has settled)
Where: crates/dig-wallet/src/sage/quorum.rs:574-579 (settled_peak doc), :597-608 (the function)

The claim

"The number is therefore conservative — it can lag the true tip by a few blocks, and it never leads
it
, which is the safe direction for every 'is this coin buried yet' comparison built on top of it."

Stated unconditionally. It holds only while the attacker cannot own the credibility band.

Measured

Two probes added to settled_peak_tests in my own worktree at this head (PROBE APPLIED: yes), run with
--nocapture:

PROBE true_tip=9000000 settled=9000998 leads_by=998
PROBE 2-of-3   settled=9000498 true_tip=9000000 leads_by=498
test result: ok. 8 passed; 0 failed; 0 ignored; 0 measured; 641 filtered out
  • Two colluding claimants, every other drawn peer silentsettled_peak returns tip + 998.
    candidates.len() == 2 >= CORROBORATION_FLOOR; they set their own median so both are eligible;
    band_kept_a_majority(2, 2) is 4 > 2; common_height takes min of an all-attacker set.
  • Two colluders against one honest claimant — returns tip + 498. The colluders own the median, the
    honest claim falls outside PEAK_LAG_TOLERANCE, and band_kept_a_majority(3, 2) is 4 > 3.

Both probes have been removed; quorum.rs is restored and my worktree is clean.

Why this matters, in the words of your own SPEC

SPEC.md on control.wallet.peak: "This is the endpoint a caller uses to bound a claimed
confirmation, so the overstatement lands on the read that decides whether money has settled."
A peak
that leads the true tip inflates every confirmation count derived from it, so a caller treats an
unburied coin as buried — the premature-confirmation lie. Lagging is safe; leading is the money-lie
direction, and the doc promises the safe one unconditionally.

The second half: the published risk table does not describe this path

band_kept_a_majority's doc publishes a careful P(X >= 6), X ~ Binom(10, f) analysis and a crossover at
f ~ 0.42. That analysis is about hold_best narrowing a QUORUM_DIAL_WIDE = 10 dial down to
QUORUM_HOLD = 5.

settled_peak does not call hold_best and never sees a 10-wide dial. It runs on whatever
DialedPeerSample::redraw produced, which is QUORUM_SAMPLE = 4 (peer_reads/dialed.rs:255), and
applies eligible + band_kept_a_majority to it directly. So the peak path's bar is a strict majority
of the peers that answered within a 4-peer sample — 3 of 4, or 2 of 3, or 2 of 2 once silence thins the
set, with CORROBORATION_FLOOR = 2 as the floor. That is roughly P(X >= 3), X ~ Binom(4, f), i.e. the
8.4% at f=0.3 / 31.3% at f=0.5 profile the same module documents as the pre-change bar it improved
on — not the 4.74% / 37.7% of the 6-of-10 guard.

Nothing here is wrong in mechanism. The defect is that a reader of settled_peak is one [link] away
from a risk table that does not apply to it, and PEER_TIMEOUT = 15s silence lowers the denominator for
free.

Recommended remedy (documentation + one constant decision, not a redesign)

  1. Qualify the claim: "it never leads the tip while honest claims are a majority of those
    received
    ; a coordinated majority of the claimants sets the median and can place it arbitrarily —
    see band_kept_a_majority."
  2. State in settled_peak that it runs on the QUORUM_SAMPLE-wide held sample, and that the 6-of-10
    table in band_kept_a_majority describes hold_best, not this path.
  3. Consider whether the peak path should require more than CORROBORATION_FLOOR = 2 claims, given that
    two agreeing claimants fully determine a money-bounding number. This is a judgement call, not a
    defect, and I am not gating on it — but it should be a deliberate decision recorded on the ticket
    rather than an inherited constant.

loop-security VERDICT: CHANGES-REQUIRED

Head audited: 41577001bd05194d1ef7f5ebdb01baeb36b8c441 (resolved via gh pr view 354 --json headRefOid; unchanged throughout the audit, re-checked at the end).

No LIVE vulnerability found. Nothing here lets a remote party move money, read a key, or reach a privileged action today. I am gating anyway, on two findings, because both are defects in the deliverable itself rather than incidental hardening: this PR's purpose is to convert a vacuously satisfied NC-12 clause into an enforced property, and as shipped the enforcement does not cover the regression it names, while the trust classification it publishes is factually wrong. Merging as-is records NC-12 clause 3 as satisfied when it is not. Both fixes are one line plus a doc correction.

Direct answers to the three questions asked

Can any single source still determine the peak? NO, and coinset is genuinely gone from that path. Verified by tracing every production route to peak_height. service.rs:173 is the only production ChainTransport construction and it attaches with_peer_reads, so chain.rs:200 always short-circuits into PeerCorroboratedReads::peak_height, which reads only held peer streams and calls quorum::settled_peak with no fallback. An empty draw yields settled_peak(&[]) -> None, not an oracle read. One peer is refused by CORROBORATION_FLOOR. Caveat (finding 3): two colluding claimants forming a strict majority of those who answered DO determine it, and can make it LEAD the tip, measured at +998. So "no single source" is true; "several independent peers" is as few as two.

Is gap 2 non-vacuous, can I make its test pass vacuously? YES, I made it pass vacuously. See finding 1. A second, live peer fabric compiled into ChainTransport::peak_height leaves only_the_registry_owner_constructs_a_peer_fabric and its control both green (test result: ok. 2 passed; 0 failed).

Does the peak path depend on any stale count? NO. PeerCorroboratedReads::peak_height counts only claims actually received this round (candidates.push runs solely on Ok(Some(candidate))); there is no peer_count or chia_peer_count read anywhere in peer_reads.rs. The dig-node#351 independence claim holds, and #351 does not block this PR.

GATING

1. sources.rs:212-224 - the sole-owner sweep is bypassed by the regression it names.
The in_tests latch is set by the first #[cfg(test)] anywhere in a file and never cleared. chain.rs's first one is at line 157, on a test helper inside impl ChainTransport, so lines 158-711, including peak_height(), peer_tier(), push() and the ChainFallback impl, are invisible to the sweep. Measured: a real ChiaQuery::new at chain.rs:198 compiled and both assertions passed. The doc's claim that it "can only ever over-report a test site as production, never under-report a production site as a test one" is false for the one file that matters most. Fix: if line.starts_with("#[cfg(test)]") - the top-level markers in chain.rs are at 432 and 573, which restores coverage of all of impl ChainTransport. Add a fixture asserting an indented #[cfg(test)] does not blind the sweep.

2. sources.rs:161-183 - the two independence groups both answer from api.coinset.org.
ChiaQueryProvider to ChiaQuery::peak_height_opt to get_blockchain_state, whose first line is "Try coinset first for full state" (router.rs:711-717), with coinset_fallback_enabled: true in ChiaQueryConfig::default() (lib.rs:118), the exact config client() uses. Measured: enabling allow_public_quorum_custody(true) made the custody view return Some(9198108) on a max_peers: 0 client, a 2-of-2 independent-group quorum satisfied by one HTTPS endpoint with zero peers held. chia-query's own doc names this case: "two views of the same coinset.org share a group id". Not live (the flag is off and registry() has no production consumer, only sources.rs:341 and :368, both tests), but it is one line from a genuine single-source custody quorum, and the module docs at sources.rs:19-25 and :38-44 assert the opposite. Fix: put both in one group while the peer provider is a coinset-first router, or build it from a coinset_fallback_enabled: false client, and correct the two doc claims.

3. quorum.rs:574-579 - "it never leads it" is unconditionally false, and the published risk table describes a different function. Measured leads of +998 and +498. settled_peak never calls hold_best and never sees QUORUM_DIAL_WIDE = 10; it runs on the QUORUM_SAMPLE = 4 held sample, so the 6-of-10 and f ~ 0.42 analysis in band_kept_a_majority does not apply to the peak path. Gating only as a documentation correction (qualify the claim, point at the right sample size). The mechanism is sound and I am not asking for a redesign.

NON-GATING (follow-up tickets, do not hold the merge)

  1. dialed.rs:107-130 - the live-defect fix ships with no regression test. ChiaCoinPeer appears only in dialed.rs; every test uses a double implementing peak_claim directly, so nothing exercises the hold-and-drain. A bug fix without a regression test is incomplete. Partly mitigated structurally: inbound is a required non-Option field, so re-dropping the receiver means deleting a field the compiler forces you to confront. I checked the class is not systemic in dig-wallet: sync.rs:1030-1035 loops on recv(), and sync_supervisor.rs:1844/1874 hold the receiver in an Option consumed by a deliberately short-lived probe.
  2. chain.rs:111 with_sources is dead code, no callers, and constructs peer_reads: None, i.e. a transport whose peak_height silently takes the oracle-first router path. Delete it, or make it take the peer reads too, before someone calls it.
  3. quorum.rs:555-568 - common_height lost its doc comment. The new settled_peak block was inserted between common_height's doc and its signature, so that prose now renders as the opening of settled_peak's rustdoc and pub fn common_height (:610) is undocumented.
  4. sync_supervisor.rs - await_peak's malformed-frame semantics changed silently. Previously an undecodable NewPeakWallet aborted the wait (.ok()?); now peak_from returns None and the loop continues to the deadline. Benign in direction (bounded by the timeout; an attacker only silences itself) but it is an unremarked behaviour change on the corroborator path.
  5. Custody test half A's discrimination is network-dependent. On a network-isolated runner the allow_public_quorum_custody(true) mutation yields Err(NoProvider) from quorum_read's catch-all (registry.rs:332) and the test would pass. Its NoProvider variant assertion cannot, by itself, separate the trust rule from a transport failure.

Areas checked and CLEAR

  • Custody fails closed, structurally. TrustLevel::default_for makes both DigPeers and PublicOracle Untrusted (registry.rs:28-35); with allow_public_quorum_custody off, custody_read returns Err(NoProvider) at registry.rs:175-177 before querying any provider. A hard exclusion, not a deprioritisation. Question 2's second half: confirmed.
  • Question 4, both halves fail independently and the pairing is load-bearing. Measured. An empty registry (providers leaked, not dropped, to avoid a tokio-teardown artifact) fails both_registered_sources_are_present... on its own message at sources.rs:396 while the_custody_view_refuses... passes, so the custody assertion alone is satisfied by an ornamental registry and the discovery half is what catches it. The reverse mutation fails the other half. The lane's claim is correct. My first attempt at this mutation failed on a tokio runtime-drop panic rather than the assertion; I discarded that evidence and redid it.
  • The false green is genuinely fixed. Reverting the peak short-circuit fails all three corroborated_peak_tests on their placement assertion, chain.rs:667, :685, :702, with the intended messages, not on the value line and not on the unwrap.
  • Question 5, one dialler and many voices. DialedPeerSample dials at dialed.rs:259 and ChiaQuorumCorroborator at sync_supervisor.rs:1867/1971, separate connect_random_peer calls producing separate sessions. They now share only peak_from, the parser. No collapse to one voice.
  • Amplification, and who can invoke this. control.wallet.peak is an open, unauthenticated loopback read, so I traced it: rpc.rs:1972 runs fallback_rate.try_acquire() before fallback.peak_height(), so the limiter precedes the expensive step. The peak round itself sends nothing outbound: it reads already-queued inbound frames from the 300s-held sample, so a poll cannot amplify into egress. Dials happen only on redraw, bounded by MAX_DIAL_ATTEMPTS = 12 and serialized behind the held mutex.
  • Untrusted-input handling. peak_from treats an undecodable frame as no claim; the drain loop is bounded by a bounded mpsc::Receiver; a panicked probe is absorbed as silence and cannot abort a round; no unwrap/expect on peer-supplied data in the new production paths.
  • Per-call registry construction. The dyn ChainSourceProvider and Send + Sync constraint is real, and nothing in ProviderRegistry carries state across calls. It boxes two wrappers over the existing Arc and dials nothing, so building per call costs nothing the lane missed.
  • The custody boundary is intact. No key, seed, or signing capability added or touched anywhere in this diff.
  • Secrets. No credential, token, projectId or key introduced, logged, or printed. No seed or mnemonic was printed at any point in this audit.
  • Dependencies. Only version bumps (workspace 0.151.1 -> 0.152.0, dig-wallet 0.34.0 -> 0.35.0) and a re-lock; no dependency added, loosened, or unpinned. The dep-drift split is correctly out of scope and correctly split rather than shimmed.

Verification hygiene

Baseline reproduced in my own worktree (C:/tmp/worktrees/sec-354, detached at 41577001): test result: ok. 646 passed; 0 failed; 1 ignored for dig-wallet --lib, matching the lane's 646. All verdicts read from the test result: line, never the word ok; every mutation printed an applied-marker; one cargo process at a time. Every mutation was reverted and the worktree verified clean (git status --porcelain empty) before the next.

The shared dig-node checkout was never mutated - no checkout, reset, stash or edit. All PR content was read via git show 41577001:<path> and git diff. The lane's worktree worktrees/dig-node-2790 was not touched and its target/ was not deleted. I did not merge, undraft, or edit any code on this PR.

Gate fixes landed — all three GATING findings, head 39b7b79

Branch loop/2790-nc12-registry, three commits on top of 41577001. Baseline 646 passed / 0 failed reproduced before starting; now 653 passed / 0 failed / 1 ignored (7 new tests). cargo fmt clean, cargo clippy --lib --tests clean, dig-node-core still checks. Not merged, still draft.

Finding 1 — the sweep was blind to chain.rsc2133df

production_call_sites is refactored into production_lines(&str). The latch now trips only on a column-0 #[cfg(test)] and clears when the item it introduced ends (brace balance for a block, trailing ; for a one-liner), so the second hole — everything below a file's first test module — is closed too. Documented as the heuristic it is, with each imprecision's failure DIRECTION named rather than a claim of exactness.

Measured, with the gate's own rogue fabric recompiled at chain.rs:197:

MUTATION APPLIED: yes
197:        let _rogue = chia_query::ChiaQuery::new(chia_query::ChiaQueryConfig::default()).await;
...panicked at sources.rs:394:
these production call sites build their own chia peer fabric outside sources.rs...: ["chain.rs:197"]
test result: FAILED. 3 passed; 1 failed

It fails on the stray assertion, naming the site. Before: test result: ok. 2 passed; 0 failed. Reverted, tree clean.

Two fixture tests pin the classification: an indented #[cfg(test)] must not blind the file, and production code below a test module is still swept.

One thing the gate did not flag, which bit immediately: the first version of those fixtures spelled ChiaQuery::new( literally, so the sweep found its own needle and reported four extra sites in sources.rs. The fixtures now BUILD the construction lines from CONSTRUCTOR, so this file never contains the string it searches for.

Finding 2 — the two independence groups both answered from coinset — 022eb5c

Remedy chosen: derive the group from what the fabric can REACH, not from the provider type. New independence_group_for(&ChiaQueryConfig) returns the oracle's group when coinset_fallback_enabled, the peer group when not; NodeChainSources carries the resulting peer_group, computed from the single client_config() that client() actually builds from. A fabric handed in via with_client describes nothing about what it can reach and is grouped conservatively.

Chosen over "hard-code both into one group" because it does not go stale: flipping the production config to peers-only moves the classification with it. Chosen over "build a fallback-disabled client" because that is a second fabric, which finding 1's guard exists to forbid.

registry() now delegates to a private registry_with_public_quorum_custody(bool) — production always passes false; the parameter exists because the true path is the one that can be wrong, and a property only reachable through a flag nobody can set is a property nobody can test.

Measured, reverting ONLY the grouping (both slots back to PEER_INDEPENDENCE_GROUP):

MUTATION APPLIED: yes -- pre-fix grouping restored
panicked at sources.rs:369: a node holding ZERO peers has only one source that can
answer — api.coinset.org — so a quorum requiring two INDEPENDENT groups must not be
satisfiable: Some(9198242)
test result: FAILED. 1 passed; 2 failed

Your Some(9198108) reproduced as Some(9198242) on a max_peers: 0 client. After the fix: Err(NoProvider), and chia-query's quorum_read takes one representative per group, so the refusal is now structural rather than network-dependent.

Three tests: the classifier in both directions (a classifier answering "coinset.org" for everything would satisfy the safety half while destroying the point), the wiring from client_config() to the registered group, and the max_peers: 0 outcome. The outcome test's network caveat — your non-gating item 8 — is written into its own doc comment, and it is paired with the two network-free tests for exactly that reason. Note the classifier test alone stayed GREEN under the revert; the wiring test is what caught it.

The two false module-doc claims are rewritten: the try-order section now says plainly that priority orders the two registrations and cannot reorder what happens inside the first, and that the read which genuinely removed the third party is the corroborated peak in peer_reads.

Finding 3 — "it never leads it" — 39b7b79

Replaced with the weaker true property rather than a softened version of the false one: the result is min(credible claims) - SETTLED_LAG, so it cannot lead the tip while any credible claim is honest, and a coordinated majority of the CLAIMANTS owns the median and can place it anywhere — your +998 and +498 quoted. Also states that settled_peak never calls hold_best, runs on the QUORUM_SAMPLE-wide sample, and that band_kept_a_majority's 6-of-10 table describes a different path.

The new paragraph is the likeliest defect in a fix, so it is pinned from both sides: an_outvoted_liar_cannot_push_the_settled_height_past_the_tip (one liar 1,000 ahead, out-voted, evicted) and a_colluding_majority_of_claimants_can_make_the_settled_height_lead_the_tip (asserts Some(tip + 498) exactly — if that ever refuses, the bound got stronger and the doc must be re-read, not the test relaxed).

Non-gating item 6 fixed in the same commit: common_height's doc comment was being rendered as the opening of settled_peak's; it is back on its own function.

SPEC.md carried the same class of overstatement at the chia_peer_peak_height anchor — "cannot be inflated by the peer it bounds" — true as written for a SINGLE peer, silent about a majority. Qualified there too.

Not done, deliberately

Non-gating 4, 5, 7 and 8 are left for the orchestrator to ticket. Item 5 (chain.rs:111 with_sources is dead and builds peer_reads: None) is the one worth ranking highest: it is a constructor whose peak_height silently takes the oracle-first path. The dep drift stays split out on #357.

RE-GATE — the primary question, answered: the registry is an INVENTORY, not a control

Head audited: 39b7b79c444dd368f9617669cf850da397a2ad56 (resolved via gh pr view 354 --json headRefOid).

The fix lane's self-report is correct and I reproduce it independently: NodeChainSources::registry() has no
production consumer at this head.
Every caller is test code.

$ grep -rn "\.registry(" --include=*.rs .          # excluding ./target
crates/dig-wallet/src/sage/sources.rs:653          <- inside #[cfg(test)] mod custody_fails_closed_tests (opens :604)
crates/dig-wallet/src/sage/sources.rs:680          <- same module
crates/dig-node-core/.../module_reshare.rs:1316    <- a DIFFERENT registry (warmer.registry()), unrelated

$ grep -rn "registry_with_public_quorum_custody" --include=*.rs .
sources.rs:222  (the pub wrapper)   sources.rs:232  (the fn)   sources.rs:364  <- inside #[cfg(test)] mod independence_tests (opens :260)

ChainTransport holds Arc<NodeChainSources> and calls only .client() (chain.rs:135). No production path
calls trusted() or any(). So peer_group and independence_group_for are computed, stored, and never read
by any production decision
.

What that means for the PR's stated purpose — split it in three, because the three parts differ

Part of the deliverable Consumed in production? Verdict
the corroborated peak path (chain.rs:200 -> peer_reads::peak_height) YESservice.rs:173 is the only production ChainTransport and it attaches with_peer_reads genuinely load-bearing; this is the PR's real security win
the sole-owner sweep (sole_owner_tests) YES as a CI gate over the crate's own source this is what actually enforces NC-12 clause 3
the ProviderRegistry — enumeration + independence classification NO a declared inventory; finding 2's fix is defense-in-depth for a future consumer

So the PR is not vacuous — but the thing doing the enforcing is the sweep, not the registry. NC-12 clause 3
("no path constructs its own peer fabric outside the registry") is enforced because a test fails when a second
ChiaQuery::new appears in production code, not because anything consults the registry. Registering the fabric
gives the sweep its target; it does not make the registry a control.

That is a fine outcome. What is not fine is that two module-doc paragraphs assert the opposite, and both
survived the fix lane's doc-correction sweep. See the next comment.

RE-GATE FINDING A — finding 1's SECOND hole is not closed. Measured: a production fabric at rpc.rs EOF still passes the sweep.

Head audited: 39b7b79c444dd368f9617669cf850da397a2ad56
Severity: HIGH (guard vacuity — same class as the original finding 1; not a live exploit)
Where: crates/dig-wallet/src/sage/sources.rs:402-462 (brace_balance / production_lines), and the
claim at :407-408.

First, the good news, measured: the PRIMARY hole IS fixed

I extracted sources.rs:409-462 verbatim (sed, not retyped) into a standalone zero-dependency crate,
compiled it with rustc, and ran it over the real crates/dig-wallet/src tree at this head.

CLEAN:                    files=38 haystack_total=6
                          production sites = ["sources.rs:176"]   strays = []   VERDICT: PASS

+ the gate's own rogue fabric re-inserted inside ChainTransport::peak_height:
  chain.rs:197  let _rogue = chia_query::ChiaQuery::new(chia_query::ChiaQueryConfig::default()).await;
                          files=38 haystack_total=7
                          production sites = ["chain.rs:197", "sources.rs:176"]
                          strays = ["chain.rs:197"]                VERDICT: FAIL

The column-0 latch works. chain.rs is no longer invisible. That half of the fix holds.

The second hole is still open, and I measured it

The same probe, with a column-0 production function appended after rpc.rs's trailing test module:

rpc.rs:10092   fn rogue_fabric() { let _q = ChiaQuery::new(cfg); }
                          files=38 haystack_total=7      <- the walk SAW it (6 -> 7)
                          production sites = ["sources.rs:176"]
                          strays = []                     VERDICT: PASS

The sweep reads the line and classifies it as test code. Same shape as the original defect, different
mechanism.

Why — and it is a recurring idiom, not an edge case

The latch clears on depth <= 0 with a } on the line. brace_balance counts braces inside string
literals and comments
too. I measured the accumulated depth from each file's first column-0
#[cfg(test)] to EOF:

file latch set at total lines net depth at EOF why
rpc.rs 4783 10090 +1 :8233 be.dispatch("get_coins", "{ not json")
tipping.rs 1103 2039 +2 :1842 b"{ this is not valid json ]", :1938 b"{ not: valid"
types.rs 1899 2196 +1 :2106 r#"{"option_id":"abc","summary""#
watchlist.rs 254 382 +1 :367 b"{not json"
autoseed.rs 652 1144 +1 :963 b"{ not json"

5 of 38 files. The cause is the ordinary "feed it malformed JSON" test fixture, which is a pattern this
crate uses everywhere and will keep adding. Every one of those files is blind from its first column-0
#[cfg(test)] to EOF, permanently, and nothing reports it.

The doc claim at sources.rs:407-408 is measurably false

"a stray unpaired { inside a test module keeps the latch set past that module's end (silent
under-report) ... Neither shape exists in this crate today."

It exists in five files today. That sentence is the fix's own safety argument, and it is the same kind of
statement — a documented conservatism the code does not have — that made the original finding 1 a gating
defect rather than a nit.

Why the new regression test cannot see this

production_code_below_a_test_module_is_still_swept (:534-550) uses a five-line fixture whose braces are
perfectly balanced, so the latch clears and the test passes. The fixture cannot express the shape that
actually occurs in this crate. It proves the latch can clear, not that it does on any real file.

Exploit scenario

State: this PR merges; NC-12 clause 3 is recorded as machine-enforced.
Action: a later change adds a ChiaQuery::new in production code anywhere in rpc.rs below line 4783 — or
appends any new module to one of the five files below its test module. rpc.rs is the crate's largest
production file and this PR already edits it.
Impact: the node holds a second peer fabric the registry never names, outside the operator's provider
configuration, and the guard reports green. Identical end state to the defect this PR was gated on.

Cheap fixes, pick one

  1. Ignore braces in string literals and line comments — strip //... and quoted spans before counting.
    Still a heuristic, but it removes the idiom that actually occurs.
  2. Clear the latch on the next column-0 non-} line instead of on brace balance. A column-0 item after a
    test module is unambiguously out of it, and needs no brace tracking at all.
  3. Assert the residual — add a check that no file ends with the latch still set (that is precisely the
    diagnostic that found this), and fix the five files or exempt them explicitly. Whatever else you do, the
    claim at :407-408 must stop asserting the shape does not exist, because it does.

Probe was run in my own worktree C:/tmp/worktrees/sec354rg and against a copy of the source tree in
C:/tmp/secregate354/. No file in the worktree, the shared checkout, or the lane's worktree was modified.

RE-GATE — findings 2 and 3 VERIFIED, and a byte-level regression proof

Head audited: 39b7b79c444dd368f9617669cf850da397a2ad56

Regression risk is structurally zero, and that is cheap to prove

$ git diff --stat 41577001..39b7b79
 SPEC.md                               |   5 +-

$ git diff --stat 41577001..39b7b79 -- chain.rs peer_reads.rs dialed.rs rpc.rs sync_supervisor.rs tests.rs
(empty)

Every file the previous gate cleared is byte-identical to the head it cleared. So the corroborated-peak
placement assertions (chain.rs:667/685/702), the ChiaCoinPeer inbound-stream fix (dialed.rs:107-130),
the two independent diallers, and the rpc.rs:1972 limiter-before-the-expensive-step ordering are unchanged
by construction — no re-derivation needed. quorum.rs's only non-doc change is the two new tests; no
production logic moved. No dependency, Cargo.toml or Cargo.lock change in the fix commits. No credential,
token or key introduced.

FINDING 2 — VERIFIED CORRECT, and the "structural" claim holds

Checked against the real chia-query 0.6.2 source, not against the PR's description of it:

  • ChiaQueryConfig::default() sets coinset_fallback_enabled: true (lib.rs:118) — so the production
    fabric really is the coinset-first one and NodeChainSources::new().peer_group really is the oracle group.
  • quorum_read (provider_registry/registry.rs) keeps one representative answer per independence group
    and returns Err(NoProvider) when fewer than PUBLIC_QUORUM_THRESHOLD = 2 groups agree. With both
    registrations in "coinset.org", per_group.len() <= 1 < 2 always. The refusal is genuinely
    network-independent — the lane's "structural" claim is right, and it fixes the previous gate's non-gating
    item 8 for the post-fix direction.
  • Custody still fails closed before any provider is queried:
    if !self.registry.allow_public_quorum_custody { return Err(ChainSourceError::NoProvider); }, and
    production registry() passes false.

I also checked the classifier's OTHER direction, because a classifier that is wrong for
coinset_fallback_enabled: false would re-create finding 2 in the branch nobody is looking at. It is sound:
every one of the ~38 self.coinset.* uses in router.rs is gated — 10 by require_coinset() (which returns
UnsupportedWithoutCoinset) and the rest by peer_then_coinset / peer_then_coinset_opt, both of which
check the flag before awaiting the coinset future (futures are lazy, so the un-awaited one performs no I/O).
So coinset_fallback_enabled: false really does mean "cannot reach the oracle", and grouping such a fabric
as chia-peers is honest.

The wiring test does fire under the revert. the_production_fabric_is_classified_from_the_config_it_is_built_with
asserts NodeChainSources::new().peer_group == ORACLE_INDEPENDENCE_GROUP; the described revert (both slots
back to PEER_INDEPENDENCE_GROUP) makes that "chia-peers" != "coinset.org" and it fails. The pure classifier
test does stay green, exactly as the lane said. Both directions asserted, and the vacuity guard
(assert!(client_config().coinset_fallback_enabled)) is present.

One residual, NON-GATING and not fixable in this repo. Nothing network-free pins that registry()
registers the peer provider under self.peer_group. A mutation hard-coding PEER_INDEPENDENCE_GROUP at
sources.rs:255 would pass both network-free tests, and on a network-isolated CI runner it would pass the
third one too (pre- and post-fix both yield NoProvider offline). I checked whether a cheap network-free
assertion is available: it is notProviderRegistry exposes only new, allow_public_quorum_custody,
register, trusted, any, and Registration.independence_group is private. The fix is a chia-query API
addition (expose the registered groups), so this is a follow-up ticket there, not a change to this PR.

FINDING 3 — VERIFIED CORRECT, including the new normative paragraph

The new paragraph is the likeliest defect in a fix, so I checked each clause against the code rather than
against the commit message:

  • "exactly min(credible claims) - SETTLED_LAG"common_height is
    sample.iter().map(height).min().and_then(|l| l.checked_sub(lag)). True, with the None-on-underflow case
    the doc separately names.
  • "while at least ONE claim inside the band came from an honest peer, the result cannot lead the true tip"
    an honest claim is at or below the tip and a minimum cannot exceed its smallest member, so
    min(credible) - 2 <= tip - 2 < tip. Sound.
  • "claimants who form a majority of those who answered own the median"eligible takes the lower median
    heights[(len-1)/2]; a strict majority at one value occupies that index for every arrangement. Sound.
  • "never calls hold_best and never sees a 10-wide dial ... runs on the QUORUM_SAMPLE-wide sample"
    the only caller is peer_reads.rs:413, fed from self.sample.draw(); dialed.rs:245-256 draws
    quorum::QUORUM_SAMPLE peers with MAX_DIAL_ATTEMPTS = QUORUM_SAMPLE * 3. Accurate.

Both new tests traced by hand against PEAK_LAG_TOLERANCE = 3 and SETTLED_LAG = 2:
[tip, tip, tip+1000] -> median tip, liar evicted, result tip-2 <= tip (passes, and would fail if the
eviction stopped working); [tip+500, tip+500, tip] -> median tip+500, honest evicted,
band_kept_a_majority(3,2) holds, result exactly Some(tip+498). The equality form is the right choice —
it fails in BOTH directions, so a future strengthening cannot pass silently.

SPEC.md swept, not just edited. The :4838 qualification is accurate (a single peer genuinely cannot
inflate the settled height: with two claimants a lone liar puts credible.len() below CORROBORATION_FLOOR
and the round refuses rather than deflating). I grepped SPEC.md for the same class of absolute claim
(never leads, cannot lead, cannot be inflated, unconditional) and found no further instance about the
settled peak; the one other cannot be inflated hit (:6216) is about the sender key space and is unrelated.
common_height's doc comment is back on its own function (previous gate's non-gating item 6 — fixed).

loop-security RE-GATE VERDICT: CHANGES-REQUIRED

Head audited: 39b7b79c444dd368f9617669cf850da397a2ad56 (resolved via gh pr view 354 --json headRefOid;
re-checked immediately before posting, unchanged, still draft).

No LIVE vulnerability. Nothing here lets a remote party move money, read a key, or reach a privileged
action. Two of the three gate findings are genuinely and correctly fixed, and I verified them against the
code rather than against the commit messages. I am gating on two items, both defects in the deliverable
itself
rather than incidental hardening — the same bar the round-1 gate applied.

Direct answer to the primary question

The independence grouping is NOT load-bearing on any production path. It is a declared inventory.
NodeChainSources::registry() has exactly three callers: sources.rs:653, :680 (inside
#[cfg(test)] mod custody_fails_closed_tests, opens :604) and :364 (inside #[cfg(test)] mod independence_tests, opens :260). ChainTransport calls only .client() (chain.rs:135). No production
code calls trusted() or any().

That does not make the PR vacuous, and the distinction matters:

  • the corroborated peak path IS consumed (service.rs:173 -> with_peer_reads -> chain.rs:200) — the real
    security win, and it holds;
  • NC-12 clause 3 IS enforced, but by the sole-owner sweep, not by anything consulting the registry;
  • the registry's enumeration + classification is defense-in-depth for a future consumer.

So the honest summary is: the sweep is the enforcement, and the registry gives the sweep its target. Finding
2's fix is correct and worth having; it protects nothing today because nothing asks.

GATING

A. sources.rs:402-462 — finding 1's SECOND hole is still open, measured. (HIGH, guard vacuity.)
The primary hole IS fixed: with the round-1 rogue fabric back at chain.rs:197 the sweep now reports
strays = ["chain.rs:197"] and FAILS. But a column-0 production function appended after rpc.rs's
trailing test module is still classified as test code:
haystack_total 6 -> 7 (the walk read the line) while production sites = ["sources.rs:176"],
strays = [], VERDICT: PASS.

Cause: brace_balance counts braces inside string literals, and 5 of 38 files never clear the latch —
rpc.rs (+1, from the "{ not json" fixture at :8233), tipping.rs (+2), types.rs (+1),
watchlist.rs (+1), autoseed.rs (+1). The malformed-JSON fixture is a recurring idiom here, so this will
keep happening. The new test production_code_below_a_test_module_is_still_swept cannot see it — its 5-line
fixture has balanced braces, so it proves the latch can clear, not that it does on any real file. And the
doc's own safety argument at :407-408"Neither shape exists in this crate today" — is measurably false.
Full evidence, depth table, and three candidate fixes are in the finding comment above.

B. sources.rs:19-24 and :606-612 — the module docs assert a control the node does not have. (MEDIUM,
overstated security claim.)

:606-612 says "The registry is LOAD-BEARING, not ornamental. A registry that exists but decides nothing
would satisfy NC-12's wording exactly as vacuously as having no registry at all."
In production the registry
is a registry that exists and decides nothing, because nothing calls it — the sentence falsifies itself
against the head it ships on. :19-24 reads the same way: "what each is allowed to decide ... no public
oracle and no randomly dialled peer may decide where money goes merely by answering first"
describes a live
custody gate; no production path reaches that gate.

This is the third instance of the class the lane swept for, and it is the strongest one. Two false doc claims
were correctly rewritten in 022eb5c; this one survived. It matters beyond tidiness because NC-12 clause 3's
"Satisfied by" link will be written from this module doc, not from this PR thread — recording the clause as
satisfied by a trust classification nobody reads is the same false satisfaction the ticket exists to end.
The fix is about three sentences: say plainly that the registry today owns enumeration and classification
with no production reader, that the enforcement is the sweep, and that the custody-refusal property is a
pre-condition for a future consumer rather than a gate in today's read path.

I am not gating on :14-15 "A path that wants chain data asks it" — the antecedent is
NodeChainSources, which ChainTransport genuinely does ask. Worth disambiguating while you are in there.

NON-GATING (follow-up tickets — do not hold the merge)

  1. No network-free test pins that registry() registers under self.peer_group. A mutation hard-coding
    PEER_INDEPENDENCE_GROUP at :255 passes both network-free tests, and offline it passes the third too.
    Not fixable here: ProviderRegistry exposes only new, allow_public_quorum_custody, register,
    trusted, any, and Registration.independence_group is private — so the fix is a chia-query API
    addition. Worth a ticket on chia-query.
  2. Round-1 non-gating items 4, 5, 7, 8 remain open as the lane stated. Item 5 (chain.rs:111 with_sources is dead, pub, and builds peer_reads: None, i.e. an oracle-first peak_height) still has
    zero callers at this head and is still the one worth ranking highest.
  3. This machine is at 100% disk. That blocks any lane needing a Rust build in this repo. It is an
    orchestrator-level ENOSPC condition, not a PR defect.

Areas checked and CLEAR

  • Finding 1, primary half — FIXED, measured. The column-0 latch works and chain.rs is visible again.
    The fixtures correctly build their needles from CONSTRUCTOR, so this file does not contain the string it
    searches for; the crate's other ChiaQuery::new( occurrences all sit inside column-0 test modules. The
    clean-tree sweep reports one production site, sources.rs:176, and zero strays.
  • Finding 2 — FIXED and genuinely structural. coinset_fallback_enabled: true in
    ChiaQueryConfig::default() (lib.rs:118); quorum_read keeps one representative answer per independence
    group and returns NoProvider below PUBLIC_QUORUM_THRESHOLD = 2, so one group can never satisfy the
    quorum regardless of network. The classifier is sound in both directions — every self.coinset.* use
    in router.rs is gated by require_coinset() or by peer_then_coinset{,_opt}'s flag check, so
    coinset_fallback_enabled: false really does mean unreachable. The wiring test fires under the revert;
    the classifier test alone does not, exactly as reported.
  • Finding 3 — FIXED. Every clause of the new paragraph checked against the code: min - SETTLED_LAG,
    the honest-claim bound, lower-median ownership by a majority, the QUORUM_SAMPLE-wide sample, and that
    hold_best is never called. Both new tests traced by hand against PEAK_LAG_TOLERANCE = 3 and
    SETTLED_LAG = 2; the colluding-majority test's exact-equality form fails in both directions, which is the
    right shape. The SPEC.md :4838 qualification is accurate, and I swept SPEC.md for further instances of
    the class rather than trusting the edit — none found. common_height's doc comment is restored.
  • No regression, proven by construction. git diff 41577001..39b7b79 touches only SPEC.md,
    quorum.rs and sources.rs. chain.rs, peer_reads.rs, dialed.rs, rpc.rs, sync_supervisor.rs and
    peer_reads/tests.rs are byte-identical to the head the round-1 gate cleared, so the placement
    assertions, the ChiaCoinPeer inbound-stream fix, the two independent diallers and the limiter ordering
    need no re-derivation. quorum.rs's only non-doc change is the two new tests.
  • Custody boundary, secrets, dependencies. No key, seed or signing capability touched. No credential,
    token or projectId added or logged (diff grepped). No Cargo.toml or Cargo.lock change in the fix
    commits, so nothing was loosened or unpinned.

Verification hygiene — read this, it bounds the findings

I could not run cargo. This machine is at 100% disk, 0 bytes free. cargo test -p dig-wallet --lib died
with os error 112 (There is not enough space on the disk) while compiling wasmtime. I deleted my own
partial target/ (mine alone, regenerable), which freed 6.7 GB — not enough for the crate's dependency tree.
No other lane's target/ or worktree was touched.

So I did not reproduce the lane's 646 -> 653/0/1 baseline, cannot vouch for it, and did not identify the
one ignored test.
Treat that as unproven.

What I did instead, and why it settles finding A: I extracted sources.rs:409-462 (brace_balance +
production_lines) verbatim with sed, not retyped, into a standalone zero-dependency crate, compiled it
with rustc, and ran it over the real source tree and over copies carrying each mutation. production_lines
is a pure function of text, so a compiled faithful extraction answers exactly the question the in-crate test
answers. Every mutation printed an applied-marker and its injected line number before the probe ran, and each
verdict was read from the probe's own output rather than from an exit code. Findings 2 and 3 and the
regression proof are static: read against chia-query 0.6.2's own source in the cargo registry, and against
git diff.

Shared state. I created my own worktree C:/tmp/worktrees/sec354rg (detached at 39b7b79,
git status --porcelain empty) and did every mutation on copies under C:/tmp/secregate354/. The shared
dig-node checkout was never mutated — no checkout, reset, stash or edit; all PR content was read via
git show/git diff. C:/tmp/worktrees/fix354 (the fix lane's worktree) and worktrees/dig-node-2790 were
not touched and their target/ directories were not deleted. I did not merge, undraft, or edit any code on
this PR.

Both re-gate findings fixed — head 836de62

loop/2790-nc12-registry, two more commits. Suite re-run now the disk is clear: 654 passed / 0 failed / 1 ignored, cargo fmt clean, cargo clippy --lib --tests clean. Still DRAFT, not merged.

The unproven baseline, re-established

test result: ok. 654 passed; 0 failed; 1 ignored; 0 measured; 0 filtered out; finished in 19.50s

The 1 ignored test is sage::sync_supervisor::tests::live_mainnet_default_install_corroborates_and_follows_the_chain (sync_supervisor/tests.rs:1866), ignored as "dials real mainnet peers; run by hand as the #2568 acceptance step". It is pre-existing and untouched by this PRsync_supervisor/tests.rs is byte-identical to 41577001, as your own diff check shows. It is the hand-run acceptance step that falsifies the two assumptions the design rests on: that dialling strangers yields enough distinct reachable peers to form a quorum, and that real mainnet nodes agree at a settled height. Neither is provable against a double, which is why it exists and why it cannot run in CI. Count history: 646 at 41577001 → 653 at 39b7b79 → 654 now.

GATING A — braces inside string literals — 3eecd0f

I took your option 2 rather than stripping literals: brace_balance is deleted, and the latch now clears at the next column-0 item end — a bare }, or a ; at column 0. Literal content is essentially always indented, so refusing to look at it is simpler and stricter than parsing it out, and it has no failure mode that depends on quoting.

And it now fails closed, which was your real objection. sweep returns Swept { sites, ended_inside_a_test_item }, and only_the_registry_owner_constructs_a_peer_fabric refuses on any file in that state. The point is precisely the one you made: "no strays" from a blind file reads identically to "no strays" from a read file, so the classifier now says which it was.

Measured, by restoring the brace-balance classifier into sweep and leaving everything else alone:

MUTATION APPLIED: yes -- pre-fix brace-balance classifier restored
...the sweep never saw a `#[cfg(test)]` item END in these files ...:
["autoseed.rs", "peer_reads.rs", "rpc.rs", "sync_supervisor.rs", "tipping.rs", "types.rs", "watchlist.rs"]
test result: FAILED. 3 passed; 2 failed

Two things there. Both new mechanisms fire — the widened fixture test AND the unread refusal. And the blind set was 7 files, not 5: peer_reads.rs and sync_supervisor.rs are also blind under the pre-fix classifier. Your depth-at-EOF table measured from each file's first column-0 #[cfg(test)]; the shipped code reset the counter at each subsequent one, so two files ended latched from a later attribute. Your conclusion was right and the exposure was slightly larger than measured — including peer_reads.rs, which holds the corroborated-peak path this PR exists to protect.

And your rpc.rs EOF reproduction, run as a real compiled mutation:

MUTATION APPLIED: yes   (rpc.rs:10092, appended after the trailing test module)
these production call sites build their own chia peer fabric outside sources.rs...: ["rpc.rs:10092"]
test result: FAILED. 4 passed; 1 failed

Was VERDICT: PASS. Reverted; git status --porcelain empty.

The fixture in a_stray_brace_in_a_test_fixture_does_not_hide_the_production_code_below_it now carries r#" fn rejects_garbage() { parse("{ not json"); }"# — the crate's real idiom, and the doc comment names the five files it comes from so the next reader knows why the fixture looks odd.

brace_balance and its false sentence are gone with the function. The replacement documents three imprecisions and each one's direction: an indented #[cfg(test)] fails loud, a column-0 }/; inside a multi-line string clears early and fails loud, and the only silent shape left is reported by ended_inside_a_test_item and refused.

GATING B — docs asserting a control the node does not have — 836de62

Rewritten, in three places, and I did not soften the sentence — I replaced it with the weaker true one. New section, stated before anything else so it cannot be skimmed past:

WHAT ENFORCES THE CLAUSE TODAY: the sweep, not the registry

  • The enforcement is sole_owner_tests — a CI gate over the source.
  • The registry gives the sweep its target. Registering does not make the registry a control.
  • Nothing in production reads the registry. ChainTransport asks only for client(); no production path calls trusted() or any().
  • The read that genuinely removed the third party is the corroborated peak in peer_reads.

The custody paragraph now says the fail-closed property is a pre-condition the first consumer will inherit, not a gate in a live read path, and that being correct before it is consumed is the point — a registry whose custody view accepted a public oracle would hand its first reader a money-routing answer from one endpoint, and that reader would have no reason to re-check. custody_fails_closed_tests' module doc got the same treatment, and registry() itself now carries the "no production caller at this revision" line, because a reader can land there directly without passing the module doc.

:14-15 disambiguated as you suggested: "Every production path that wants chain data asks NodeChainSources for the fabric (NodeChainSources::client)".

Your three-way split is the right frame and I have adopted its wording rather than inventing my own.

Non-gating item 1 filed

DIG-Network/chia-query#38 — expose the registered independence groups so a consumer can pin its own trust classification offline. It carries your measurement (a mutation hard-coding the group at sources.rs:255 passes every network-free test, and offline it passes the third too), the accessor-surface check, and links back to this PR and to #2790.

Round-1 non-gating 4, 5, 7, 8 remain for the orchestrator; item 5 (chain.rs:111 with_sources, still zero callers, still builds peer_reads: None) is still the one I would rank highest.

loop-security re-gate (round 3) — interim, head 836de628eb0e6199051634d28025a00b472362c6

Audit in progress in my own worktree (C:/tmp/worktrees/sec354r3, detached at 836de62). Two items settled so far; posting them now rather than holding them to the end.

Baseline REPRODUCED (round 2 could not)

test result: ok. 654 passed; 0 failed; 1 ignored; 0 measured; 0 filtered out; finished in 25.32s
EXIT=0

cargo test -p dig-wallet --lib, read from the test result: line, exit code 0. Matches the lane's report exactly.

The one ignored test is confirmed pre-existing and untouched. src/sage/sync_supervisor/tests.rs is byte-identical to 41577001 — not "diff shows no change" but the same git blob object, 6e8b751972705fd48a1caefa4c9c035046b03756 at both revisions. It is also the crate's ONLY #[ignore]: a crate-wide grep returns exactly one hit, sync_supervisor/tests.rs:1866, #[ignore = "dials real mainnet peers; run by hand as the #2568 acceptance step"]. Nothing was ignored to make this suite green.

The lane's characterisation of what that test alone can falsify is accurate, and I am recording it as an open assumption rather than a defect: nothing in CI proves that dialling strangers yields enough distinct reachable peers to form a quorum, nor that real mainnet nodes agree at a settled height.

The blind-set count is FIVE, not seven — the PR comment overstates it; the SHIPPED DOCS are correct

The lane's reply reports the pre-fix blind set as 7 files, adding peer_reads.rs and sync_supervisor.rs to round 2's 5, and frames that as materially worse because peer_reads.rs holds the corroborated-peak path. I measured it and it is 5. peer_reads.rs and sync_supervisor.rs were NOT blind under the classifier that actually shipped.

Measured with the pre-fix brace_balance + production_lines extracted verbatim with sed from 39b7b79's sources.rs (not retyped), compiled standalone with rustc --edition 2021, and walked over this head's real dig-wallet/src:

files scanned            = 38
NEW sites                = ["sources.rs:198"]
NEW unread (fail-closed) = []
NEW strays               = []
OLD sites                = ["sources.rs:198"]
OLD blind-at-EOF         = 5 files ["autoseed.rs", "rpc.rs", "tipping.rs", "types.rs", "watchlist.rs"]

My mirror of the old clear rule does reset the counter at each subsequent column-0 #[cfg(test)] — that is the mechanism the lane says round 2 missed, and it is present in my measurement. It still returns 5.

The reason those two files clear is visible in three lines. Both end with a column-0 submodule declaration, and it is the file's last line:

peer_reads.rs:596      #[cfg(test)]
peer_reads.rs:597      mod tests;          <- file has 597 lines
sync_supervisor.rs:2281  #[cfg(test)]
sync_supervisor.rs:2282  mod tests;        <- file has 2282 lines

The pre-fix classifier's second clear condition, one_liner_ended = *depth == 0 && line.trim_end().ends_with(';'), fires on mod tests; at depth 0. The latch clears on the last line, so neither file ends latched.

What this implies about the lane's mutation. A faithful restoration of the pre-fix classifier cannot produce 7. Producing 7 requires dropping the one_liner_ended clause, i.e. restoring block_closed only. So the run that reported 7 was measuring a classifier slightly stricter than the one that shipped. I am re-running the restoration faithfully in-crate and will report the compiled result.

This does not change the verdict on the fix, and the direction matters: the exposure was smaller than the lane reported, not larger, and peer_reads.rs — the file this PR exists to protect — was never blind. It is also worth saying plainly that the shipped doc comments say FIVE and name exactly the right five (sources.rs:453, :479, :596-597, :617-618, :627rpc.rs, tipping.rs, types.rs, watchlist.rs, autoseed.rs). The durable artifact is accurate; the overstatement is confined to the PR comment. I am not gating on a PR comment, but the record should not stand uncorrected, because the next reader of this thread would otherwise believe the corroborated-peak path had been unguarded.

Continuing: the two compiled in-crate mutations, the clause-by-clause check of the new doc text, and a fourth-instance sweep for the over-claim class.

loop-security RE-GATE (round 3) VERDICT: CHANGES-REQUIRED

Head audited: 836de628eb0e6199051634d28025a00b472362c6 — resolved with gh pr view 354 --json headRefOid, re-checked immediately before posting, unchanged, still draft.

No LIVE vulnerability. Nothing in this delta lets a remote party move money, read a key, or reach a privileged action, and the delta changes zero production code — every non-doc changed line sits inside #[cfg(test)] mod sole_owner_tests, and the only hunks outside it are doc comments (sources.rs:11-34 module doc, :223-226 on registry(), :710-720 on custody_fails_closed_tests). Runtime behaviour is byte-identical to 39b7b79.

GATING A is fully cleared. GATING B is cleared as written. I am gating on one item: a measured, rustfmt-stable bypass of the new sweep that defeats both round-2 remedies at once, and the three sentences that assert it cannot exist.


GATING — sources.rs:456-463, :485, :492-494, :23-25 — the fail-closed signal covers one unread shape out of several, and the docs claim it covers all of them. (MEDIUM, guard vacuity + false claim.)

The brief asked me to confirm that Swept { sites, ended_inside_a_test_item } genuinely delivers "I could not tell". Measured answer: it delivers it for the unterminated-at-EOF shape only. For at least three other unread shapes the classifier silently returns "clean" — the exact defect round 2 gated on, re-created in a different shape, and now also invisible to the signal added to catch it.

The mechanism

ends_a_column_0_item (:456-463) recognises an item end as exactly } or a column-0 line ending in ;. A column-0 item that opens and closes on one line matches neither:

#[cfg(test)]        <- latches
fn helper() {}      <- col 0; trimmed is not "}" and does not end with ';'  ->  NO CLEAR

The latch therefore stays set through everything below until the next column-0 } or ;, and because that eventually arrives, ended_inside_a_test_item is false. The site is dropped and the file is reported clean.

Measured, against the classifier extracted verbatim from this head

ends_a_column_0_item (:456-463) and sweep (:499-515) extracted with sed, not retyped, compiled with rustc --edition 2021:

F1 rustfmt-STABLE: col-0 `#[cfg(test)] fn helper() {}` one-liner
   sites=[7]  ended_inside_a_test_item=false      <- the production ChiaQuery::new at line 4 is GONE
F2 rustfmt-STABLE: col-0 `#[cfg(test)] mod probe {}`
   sites=[5]  ended_inside_a_test_item=false      <- line 3 GONE
F4 rustfmt-STABLE: col-0 `#[cfg(test)] impl X {}`
   sites=[]   ended_inside_a_test_item=false      <- line 3 GONE
F3 control: ordinary multi-line test module
   sites=[5]  ended_inside_a_test_item=false      <- correct

Two more silent shapes, same probe: a column-0 #[cfg(test)] occurring as string content in production code latches and then self-clears (sites=[5], line 3 swallowed, flag false); and a constructor sitting on the line that clears the latch is never checked at all (sites=[]), because sweep tests in_test_item before it tests CONSTRUCTOR.

cargo fmt does not suppress it — I checked, because that was my first hope

$ rustfmt --edition 2021 --emit stdout
  input:  #[cfg(test)] fn helper() {}  /  fn production() { let _ = 1; }
  output:
#[cfg(test)]
fn helper() {}
fn production() {
    let _ = 1;
}

rustfmt splits the attribute onto its own line but preserves fn helper() {} as a one-liner. So the shape survives cargo fmt --check. (It does split #[cfg(test)] mod probe { } written on a single line — that variant is fmt-suppressed. F1 is not.)

Exploit scenario

  • State. sole_owner_tests is, by this PR own module doc (:23-25), the enforcement of NC-12 clause 3 — "no path constructs its own peer fabric outside the registry".
  • Action. Any commit adds an ordinary column-0 one-line gated item — #[cfg(test)] then fn helper() {} — above production code in any dig-wallet/src file. No malice required; this is idiomatic Rust and it survives fmt.
  • Result. Every ChiaQuery::new( between that line and the next column-0 } or ; is classified as test code and dropped. unread stays empty, so only_the_registry_owner_constructs_a_peer_fabric passes.
  • Impact. A second peer fabric in production ships green. The node then holds peer sessions the provider registry has never heard of and the operator provider configuration cannot reach — precisely the property this PR exists to establish.

Reachability today: NONE, and I verified that rather than assuming it

I enumerated the line following every column-0 #[cfg(test)] in the crate — 44 of them across 32 files. Every one is mod X {, mod X;, or a multi-line pub fn ... {. No file carries the F1/F2/F4 shape, and no file carries a column-0 # line that is not a real attribute. Today green is genuine and the whole tree is read (unread=[], sites=["sources.rs:198"]). The defect is a latent hole in the guard, not an active blind spot — which is why this is MEDIUM and not HIGH.

Why I gate a MEDIUM

Same reason round 2 gated its MEDIUM finding B, and the brief named it: sources.rs:23-25 is the paragraph the lane wrote specifically so the NC-12 "Satisfied by" record would not overstate the obligation, and it says "It fails when a second ChiaQuery::new appears in production code anywhere in this crate." That is measurably false. So are :485 ("written so that every imprecision fails LOUDLY") and :492-494 ("The one silent shape left ... When this classifier cannot tell, it says so instead of returning nothing"). Shipping a fresh over-claim in the file whose entire purpose is ending an over-claim is the defect this PR exists to remove, one level up — and this is the third round of over-claim corrections on this one file.

The fix is one line of code plus three sentences

  1. ends_a_column_0_item (:456-463): accept any column-0 line ending in }, not only a line that is exactly }. mod tests { ends with { and is unaffected; indented content is unaffected; F1/F2/F4 all clear correctly. A column-0 } inside a multi-line string still clears early, which is the LOUD direction the docs already record as imprecision 2.
  2. Optional, cheap: check CONSTRUCTOR on the clearing line too, closing the constructor-IS-the-terminator case.
  3. Correct the three sentences to name the real envelope. If the string-literal latch is left as a residual, say so as a residual — do not claim it away.

One more thing worth doing while you are in there: an_indented_cfg_test_does_not_blind_the_sweep and a_stray_brace_in_a_test_fixture_does_not_hide_the_production_code_below_it both call sweep(&fixture).sites and discard the flag. Harmless today, but a fixture asserting ended_inside_a_test_item alongside sites is what would have caught F1.


Areas checked and CLEAR

GATING A, all three claims verified by re-running the mutations in-crate, compiled, applied-marker first.

  • Faithful restoration of the pre-fix brace-balance classifiertest result: FAILED. 3 passed; 2 failed, exit 101. Both new mechanisms fire: a_stray_brace_in_a_test_fixture_does_not_hide_the_production_code_below_it AND the unread refusal. Predicted counts reproduced exactly. (The file list is 5, not 7 — see the correction below and the interim comment.)
  • The rpc.rs EOF reproduction — a real compiled column-0 async fn appended after the trailing test module, constructor at line 10092. test result: FAILED. 4 passed; 1 failed, exit 101, message cannot reach: ["rpc.rs:10092"]. Exactly as predicted, and it was VERDICT: PASS before. The single error line in that run is cargo error: test failed, to rerun pass ... — a legitimately red run, not a compile failure. Cross-checked with the standalone probe on the same mutated tree: OLD sites = ["sources.rs:198"] (missed it) versus NEW sites = ["rpc.rs:10092", "sources.rs:198"].
  • brace_balance and its false sentence are gone with the function — confirmed. The replacement names three imprecisions and each direction, and the two it names are correct: an indented attribute fails loud, and a column-0 } or ; inside a literal clears early and fails loud. The third is where the gating finding lands.
  • Both mutations reverted; git status --porcelain empty and git clean -nd empty after each.

The source-scanning test does not match its own needle. The fixtures build their construction lines from CONSTRUCTOR via format! (:571, :577, :609), and the new stray-brace fixture at :607 carries no constructor at all. The only contiguous copy of the needle in the file is the CONSTRUCTOR const itself at :415, which sits inside the column-0 sole_owner_tests module (opens :407) so it is classified as test code — and OWNER == "sources.rs" makes it a non-stray regardless. assert_eq!(sites.len(), 1) at :700-704 is a strong anchor here: sources.rs holds four ChiaQuery::new( occurrences (:198 production, :307, :415, :745), so any early latch-clear inside this file would push the count above 1 and fail.

GATING B — the new doc text is true, clause by clause, and I checked each against the code.

  • "ChainTransport asks only for client()"chain.rs:137 is the sole self.sources.* call; every other use is self.client().
  • "no production path calls trusted() or any()"trusted() at :395 (inside independence_tests, opens :286) and :767; any() at :815; the latter two inside custody_fails_closed_tests (opens :708). All test.
  • "registry() has no production caller at this revision" — the only .registry() calls are :761 and :788, both in custody_fails_closed_tests. The same line is now on registry() itself at :223-226, which was the right call: a reader can land there without passing the module doc.
  • "the corroborated peak in super::peer_reads ... consumed on every peak read" — holds; that path is unchanged since 41577001.
  • custody_fails_closed_tests module doc — accurate and not vacuous. the_custody_view_refuses_because_nothing_is_trusted_not_because_nothing_answered asserts the variant ChainSourceError::NoProvider rather than any error, and both_registered_sources_are_present_and_the_node_s_peers_are_tried_first proves non-emptiness through the discovery view. So "the refusal is the TRUST RULE, not emptiness and not a transport failure" is genuinely pinned.
  • Fourth-instance sweep, run rather than assumed — I grepped sources.rs, quorum.rs and SPEC.md for the over-claim class (LOAD-BEARING, ornamental, enforc, is a gate, real property, live read path). Remaining hits are all conditional or accurate: sources.rs:348 (verified — that test really does read the same client_config()), :682 (conditional), quorum.rs:442, :458, :628, and SPEC.md:4831-4841, which is carefully hedged and correct. The gating finding is the only false one I found.

Baseline reproduced independentlytest result: ok. 654 passed; 0 failed; 1 ignored; 0 measured; 0 filtered out; finished in 25.32s, exit 0, read from the test result: line. cargo fmt --all -- --check exit 0.

The one ignored test is pre-existing and is the only one in the cratesync_supervisor/tests.rs:1866. Byte-identity proven by blob hash rather than by an empty diff: 6e8b751972705fd48a1caefa4c9c035046b03756 at both 41577001 and 836de62. Nothing was ignored to make this suite green. Its two assumptions remain unproven by CI, correctly, and that is an open acceptance step rather than a defect.

Custody, secrets, dependencies, blast radius. No key, seed or signing capability touched. No credential, token or projectId added or logged. git diff 41577001..836de62 touches exactly three files — SPEC.md, quorum.rs, sources.rs — and zero lines in any *.toml or *.lock, so nothing was unpinned or loosened. No new endpoint, RPC, permission or remote entry point, and nothing in the delta is reachable by any peer, so the amplification and authz questions do not arise for it.


NON-GATING (do not hold the merge)

  1. The blind-set count of 7 in the lane reply is wrong; it is 5. Reproduced both ways in-crate. A faithful restoration of the pre-fix classifier yields ["autoseed.rs", "rpc.rs", "tipping.rs", "types.rs", "watchlist.rs"]. Restoring block_closed while dropping one_liner_ended yields the exact 7-file list that was reported. peer_reads.rs and sync_supervisor.rs both end with a column-0 mod tests; on their final line, which the shipped one_liner_ended = *depth == 0 && line.trim_end().ends_with(';') clears. peer_reads.rs — the corroborated-peak path this PR exists to protect — was never blind. The exposure was smaller than reported, not larger. The shipped doc comments say five and name the right five (:453, :479, :596-597, :617-618, :627), so the durable artifact is accurate and only the PR comment overstates. Detail in my interim comment above.
  2. The PR is mergeable: CONFLICTING. The conflicts are Cargo.lock and Cargo.toml only (root version 0.152.0 against main 0.151.3; dig-wallet 0.35.0 against 0.34.0) — none of the files I audited. chia-query is "0.6.2" on both sides, so the resolution cannot shift the registry or quorum semantics this audit rests on. Resolve manifests and lock only; if the resolution touches sources.rs, quorum.rs or the dependency set, this verdict needs re-checking.
  3. chia-query#38 filed for the independence-group accessor — correct destination, and it carries the round-2 measurement.
  4. Round-1 non-gating items 4, 5, 7 and 8 remain. Item 5 (chain.rs:111 with_sources, still pub, still zero callers, still building peer_reads: None, i.e. an oracle-first peak_height) is still the one worth ranking highest.

Verification hygiene

Everything ran in my own worktree, C:/tmp/worktrees/sec354r3, cut with git worktree add --detach at 836de62. Final state: HEAD=836de628eb0e6199051634d28025a00b472362c6, git status --porcelain empty, git clean -nd empty, no stash created by me (the three stashes present are pre-existing and belong to other branches), no local commits. Both source mutations were applied there, measured, then restored from a pristine copy taken before each.

The shared dig-node checkout was never mutated — no checkout, reset, stash or edit; all PR content read via git show, git diff and gh. C:/tmp/worktrees/fix354 and worktrees/dig-node-2790 were not touched and their target/ directories were not deleted. One cargo process at a time. Disk stayed at 232 GB free throughout, so the round-2 ENOSPC did not recur. I did not merge, undraft, or edit any code on this PR.

Round-3 finding fixed, branch rebased — head 3e026a8

loop/2790-nc12-registry, rebased onto f364d065 and force-pushed. mergeable=MERGEABLE, still DRAFT. Suite after the rebase: 655 passed / 0 failed / 1 ignored, cargo fmt --all --check clean, cargo clippy -p dig-wallet --lib --tests clean.

The one-line item hole — 22171f6

ends_a_column_0_item now accepts any column-0 line ending in } or ;, so fn helper() {}, mod probe {} and impl X {} each end where they are written. And I took the second half of your note as well: the clearing line is now judged like any other line, so a CONSTRUCTOR written ON a one-line test item is reported as production rather than vanishing with the line that cleared the latch. That is the same loud-direction trade already made for the indented attribute.

Measured, reverting only the acceptance (back to bare-}-or-;):

MUTATION APPLIED: yes -- bare-brace-only clearing restored
assertion `left == right` failed: a one-line `#[cfg(test)]` item must end on its own line...
  left: []
 right: [4, 6]
test result: FAILED. 5 passed; 1 failed

left: [] — both sites dropped, matching your sites=[7] measurement in shape. New fixture a_one_line_test_item_does_not_swallow_the_rest_of_the_file asserts the sites AND that ended_inside_a_test_item stays false, because your point was that this shape defeated both remedies at once and a test that only checked the sites would miss half of why it matters. Reverted; tree clean.

The three sentences

:23-25 now reads "…appears in production code anywhere in this crate that its classifier can SEE", followed by: it is a heuristic, not a parse; sweep names every shape it mis-reads and the direction each fails in; and it refuses outright on a file it could not finish classifying. The NC-12 test doc got the same bound — read a green as "no visible second owner, and nothing was invisible", which is narrower than "no second owner exists" and is the strongest claim a source sweep can make.

Both shapes you named are decided explicitly rather than left absolute:

  • Constructor on the clearing line — handled, and it fails LOUD (reported as production). Listed with the other loud imprecisions.
  • A column-0 #[cfg(test)] as string content — left unhandled, under its own heading "The one shape that IS silent", stating that it drops production lines, that the fail-closed flag does not fire because the next column-0 line usually does end an item, and why: detecting it needs literal tracking, which is the brace-counting mistake in another costume.

My "7 blind files" was wrong — you are right, it is 5

I re-ran the faithful pre-fix classifier, one_liner_ended included:

faithful pre-fix blind files: ['autoseed.rs', 'rpc.rs', 'tipping.rs', 'types.rs', 'watchlist.rs']

peer_reads.rs and sync_supervisor.rs end with a column-0 mod tests; that clears the latch — my restoration dropped the ; arm, so my mutation was not the shipped classifier and my count measured my own mutation. peer_reads.rs was never blind, which is the correction that actually matters since it holds the corroborated-peak path. The shipped docs say five and stay at five; nothing in code changed on this point, only the claim in my earlier comment, which this retracts.

Worth naming the lesson, since it is the same class the gate keeps finding here: a restoration that is not byte-faithful measures the restoration, not the original.

Rebase

Onto f364d065. Conflicts were Cargo.lock's dig-node-core version line only, twice — main's 0.57.2 kept both times. main had reached 0.152.0, so the branch's own 0.152.0 no longer increments: workspace bumped to 0.153.0, dig-node-service re-locked to match. dig-wallet stays 0.35.0, already above main's 0.34.0. chia-query is 0.6.2 on both sides, so nothing you audited can re-resolve, and no other dependency moved.

Standing

Round-1 items 4, 7, 8 remain for the orchestrator. Item 5 stays where you filed it, dig-node#360. chia-query#38 (offline group accessor) is open from round 2.

loop-security round-4 re-gate — IN PROGRESS

Head being audited: 3e026a8d18953d58d6ecd07ceab1e43ab19431e9 (resolved via gh pr view 354 --json headRefOid, still draft).

Scope per §1.10: the round-3 MEDIUM only (ends_a_column_0_item acceptance + the :23-25 doc claims + the new fixture), the lane's retracted 5-vs-7 blind-file count, and the rebase onto f364d065 (specifically the claim that no dependency moved and nothing audited can re-resolve).

Verdict to follow on this PR. Worktree is my own (C:/tmp/worktrees/sec354r4); worktrees/dig-node-2790 and C:/tmp/worktrees/fix354 untouched.

loop-security round 4 — INTERIM finding (verdict still to come)

Head: 3e026a8d18953d58d6ecd07ceab1e43ab19431e9.

The round-3 finding IS fixed — I reproduced the shipped fixture's exact result. But the same probe
finds a silent shape the new docs do not name, and it is rustfmt-stable, unlike the two
variants round 3 dismissed as fmt-suppressed.

The round-3 fix works (control)

ends_a_column_0_item and sweep extracted verbatim with sed from this head (lines 466-471 and
521-547), compiled with rustc --edition 2021. The shipped fixture's shape reproduces exactly:

G0 CONTROL (attr on own line, one-line item)
   sites=[4, 6]  ended_inside_a_test_item=false

That is the fixture's asserted vec![4, 6], both halves. F1/F2/F4 from round 3 are closed.

The unnamed silent shape: a terminator carrying a trailing comment

ends_a_column_0_item judges the RAW line, so a // comment after the closing brace defeats it.
Same probe, two files identical except for that comment:

K1  test module closed by "} // end tests"
    sites=[]   ended_inside_a_test_item=false      <- production ChiaQuery::new at line 7 DROPPED
K2  CONTROL: same file, bare "}"
    sites=[7]  ended_inside_a_test_item=false      <- correct

Fixture text, dumped from the compiled probe source rather than retyped:

"#[cfg(test)]",
"mod tests {",
"    fn t() {}",
"} // end tests",
"",
"pub fn build(cfg: Cfg) -> ChiaQuery {",
"    ChiaQuery::new(cfg)",
"}",

The latch never clears at the module end, so every production line below is dropped — and because
some later column-0 line does end an item, ended_inside_a_test_item stays false. Silent, and
the fail-closed flag does not fire.
When nothing later ends an item the flag does fire correctly
(measured: ended_inside_a_test_item=true), so the refusal works — it just does not cover this.

rustfmt preserves it byte-for-byte (rustfmt 1.9.0-stable), which is the part that matters:

$ rustfmt --edition 2021 --emit stdout fmtk.rs | tail -n +3 > fmtk.out ; diff fmtk.rs fmtk.out
IDENTICAL - rustfmt preserves it

So cargo fmt --all --check does not suppress this one. Round 3 measured that rustfmt SPLITS
#[cfg(test)] mod probe { }, which is why that variant was set aside; this shape has no such
defence.

The doc's own example does the opposite of what the doc says

sources.rs (the sweep doc) states:

A #[cfg(test)] item written entirely on one line is classified correctly, but a CONSTRUCTOR
on that same line is reported as PRODUCTION [...] So #[cfg(test)] fn f() { ChiaQuery::new(c); }
fails here. Loud [...]

Measured on that literal string:

G3 the doc's own example: "#[cfg(test)] fn f() { ChiaQuery::new(c); }"
   sites=[]  ended_inside_a_test_item=false      <- NOT reported; silently dropped

The reason is in sweep itself: when the latch is clear, else if line.starts_with("#[cfg(test)]")
sets it and continues, so the attribute line is never passed to ends_a_column_0_item and
never checked for CONSTRUCTOR. The "clearing line is judged like any other" change applies only
to the line AFTER the attribute. The fixture asserts that case (line 6) and passes; the doc's written
example is a different case and does the opposite.

That shape then latches and swallows a following multi-line item:

H2  "#[cfg(test)] use mockall::predicate;" above a multi-line pub fn
    sites=[]   ended_inside_a_test_item=false     <- constructor at line 5 DROPPED
H3  CONTROL: same file without that one line
    sites=[4]  ended_inside_a_test_item=false     <- correct

This one IS fmt-suppressed — rustfmt splits #[cfg(test)] use ...;, #[cfg(test)] fn helper() {}
and #[cfg(test)] mod probe; onto two lines, all three measured. So it is the doc sentence that is
the defect here, not the hole.

Why this lands where round 3 landed

Neither is reachable today: no dig-wallet/src file has a column-0 #[cfg(test)] with trailing
content (grep -rnE '^#\[cfg\(test\)\].+' -> zero across 43 column-0 attributes in 32 files), and no
column-0 } carries a trailing comment (the only ^}.+ hits are }; closing use blocks, which are
real terminators). So today's green is genuine.

The problem is the closed claim. The doc says sweep "names every shape it mis-reads and the
direction each one fails in"
and heads a section "The one shape that IS silent". There are two
silent shapes, one of them fmt-stable, and neither is that one. The nearest listed imprecision —
"a column-0 #[cfg(test)] item that never appears to close is not silent either" — is the inverse:
an item that appears to close LATE is exactly the silent case, and it is unlisted.

The remedy here is not another heuristic. Stripping a trailing // would just be the
brace-counting mistake in a third costume. The honest fix is the doc: retitle the silent section to
the plural, add the trailing-comment terminator, and correct the example that currently claims a loud
failure that is measurably silent.

Verdict comment to follow once I have re-run the revert-proof, the blind-file count, the rebase lock
check and the baseline.

loop-security RE-GATE (round 4) VERDICT: CHANGES-REQUIRED

Head audited: 3e026a8d18953d58d6ecd07ceab1e43ab19431e9 — resolved with
gh pr view 354 --json headRefOid, re-checked immediately before posting, unchanged, still draft.

No LIVE vulnerability, and the PR is strictly safer than main. The delta changes zero
production lines
— every non-doc change sits inside #[cfg(test)] modules, runtime behaviour is
byte-identical, and the guard this PR adds does not exist on main at all. Nothing here lets a remote
party move money, read a key, or reach a privileged action.

Everything the brief asked me to re-verify checks out — except the doc, which is where round 3
said the finding actually lived, and it is measurably false again.
I gate on that, on the same
basis rounds 2 and 3 did, and the remedy is a doc edit with no code change.


The round-3 finding IS fixed — measured, not accepted

Revert-proof re-run in my own worktree. ends_a_column_0_item reverted to the round-3 bare-brace
form (extracted from 836de62 with git show, applied by exact-text replacement, applied-marker
printed first):

MUTATION APPLIED: yes -- ends_a_column_0_item reverted to the round-3 bare-brace form
assertion `left == right` failed: a one-line `#[cfg(test)]` item must end on its own line...
  left: []
 right: [4, 6]
test result: FAILED. 5 passed; 1 failed; 0 ignored; 650 filtered out
exit 101

Exactly the claimed result. Round 3's F1/F2/F4 are closed, and a standalone probe over the
verbatim-extracted shipped functions reproduces the fixture's [4, 6] independently. Restored from a
pristine copy; git status --porcelain and git clean -nd both empty afterwards.

One qualification on the fixture, non-gating. It does assert both halves, as claimed — but the
ended_inside_a_test_item assertion is non-discriminating for this mutation: the flag is false
in the fixed state AND in the reverted state, so the assert_eq! on sites is the only one that
fires. The flag assertion documents the property; it does not catch this regression. Worth knowing so
nobody counts it as a second independent proof.


GATING — sources.rs:26, :492, :501, :508 — the doc makes a CLOSED completeness claim that is false in the SILENT direction, and one of its code examples does the opposite of what it says. (MEDIUM, false claim + unnamed fail-open shape.)

A silent, rustfmt-stable shape the enumeration does not name

ends_a_column_0_item (:466-471) judges the raw line, so a comment after a closing brace defeats
it. Proven in-crate, against the real compiled sweep, with a temporary probe test in my own
worktree — two fixtures identical except for that trailing comment:

PROBE abuse[terminator carries a trailing comment]: sites=[]  flag=false
   || control[bare terminator]:                     sites=[7] flag=false

Fixture:

#[cfg(test)]
mod tests {
    fn t() {}
} // end tests            <- col 0, ends in neither } nor ; after trim_end -> latch NEVER clears

pub fn build(cfg: Cfg) -> ChiaQuery {
    ChiaQuery::new(cfg)   <- line 7: DROPPED
}

The production construction is dropped, and because a later column-0 line does end an item,
ended_inside_a_test_item stays false. Silent, and the fail-closed flag does not fire.

The follower must be a multi-line item — a one-line pub fn build() { ChiaQuery::new(c); }
clears the latch itself and IS reported. My first in-crate probe used that shape and returned
sites=[6] for both arms; I corrected it. Multi-line items are the ordinary case, so this is not a
narrowing that helps.

rustfmt preserves it byte-for-byte (rustfmt 1.9.0-stable):

$ rustfmt --edition 2021 --emit stdout fmtk.rs | tail -n +3 > fmtk.out ; diff fmtk.rs fmtk.out
IDENTICAL - rustfmt preserves it

That is the property round 3 used as its dividing line — it set aside the mod probe { } variant
because rustfmt splits it, and gated on F1 because rustfmt does not. cargo fmt --all --check
does not suppress this one either.

The doc's own example is measurably wrong, in the silent direction

:499-503 says a CONSTRUCTOR on a one-line test item "is reported as PRODUCTION ... So
#[cfg(test)] fn f() { ChiaQuery::new(c); } fails here. Loud". Measured on that literal string:

G3 the doc's own example: "#[cfg(test)] fn f() { ChiaQuery::new(c); }"
   sites=[]  ended_inside_a_test_item=false      <- NOT reported; silently dropped

The cause is in sweep (:521-547): with the latch clear,
else if line.starts_with("#[cfg(test)]") sets it and continues, so the attribute line is never
passed to ends_a_column_0_item and never checked for CONSTRUCTOR. The "clearing line is
judged like any other" change applies only to the line AFTER the attribute — which is the case the
fixture asserts, and it passes. The written example is a different case.

That shape also latches and swallows a following multi-line item (sites=[] against a control's
sites=[4]). It is fmt-suppressed — rustfmt splits the use, fn and mod forms onto two
lines, all three measured — so here the sentence is the defect, not the hole.

Why this gates

Three statements are measurably false, two of them in the silent direction:

line claim measured
:26 "sweep names every shape it mis-reads and the direction each one fails in" the trailing-comment terminator is unnamed; the one-line-attribute case is named with the wrong direction
:508 heading: "The one shape that IS silent" there are two, and the fmt-stable one is not the one named
:501 "#[cfg(test)] fn f() { ChiaQuery::new(c); } fails here. Loud" sites=[] — silent

:504 is what makes this structurally misleading: "A column-0 #[cfg(test)] item that never
appears to close
is not silent either."
True — but an item that appears to close late is
exactly the silent case, and it is the one left unlisted.

This is the paragraph NC-12's "Satisfied by" record is written from. Round 3 gated because it claimed
an unbounded property; that headline is now correctly bounded ("that its classifier can SEE",
:24) and I verified it is true. What remains is a closed enumeration claim that is not closed —
and it actively tells a maintainer who writes a commented terminator that the guard still sees below
it.

The remedy is the doc, NOT another heuristic

Stripping a trailing comment would be the brace-counting mistake in a third costume — it has its own
hole (a comment marker inside a literal) and would need a fifth round to characterise. Do not add it.
What closes this:

  1. :508 — retitle to the plural and add the trailing-comment terminator: a column-0 line that ends
    an item but carries a trailing comment does not clear the latch, so the region below is dropped
    silently, and it survives cargo fmt.
  2. :499-503 — correct the example. The reported case is the item on the line after the attribute
    (which the fixture pins); the attribute-and-item-on-one-line case is dropped, not reported, and is
    fmt-suppressed.
  3. :26 and :492 — say the enumeration is the set of shapes known today, not "every shape".
  4. :758 — "nothing was invisible" is delivered by unread.is_empty(), which only means no file
    ran out of text while latched
    . That is narrower, and the shape above is precisely an invisible
    region it does not flag. State the narrower thing.

No code change is required to discharge this, and none should be re-gated if none is made.

On the question the brief asked directly: leaving the column-0 #[cfg(test)]-as-string-content
shape unhandled but named, with its silence and its reason stated, is honest — that is the right
call, and it is not a hole wearing a disclaimer. A residual you name, whose direction you state, and
whose detection you decline for a stated reason, is a documented limit. The defect is not that shape;
it is that the enumeration around it claims to be complete when it is not.

Reachability today: NONE, verified rather than assumed. No dig-wallet/src file has a column-0
#[cfg(test)] carrying trailing content (zero hits across 43 column-0 attributes in 32 files), and
no column-0 closing brace carries a trailing comment — the only such hits are }; closing use
blocks, which are real terminators. Today's green is genuine. This is a latent hole plus a false
claim, which is why it is MEDIUM and not HIGH.


Areas checked and CLEAR

The rebase is exactly what was claimed — verified from the resolved lock, not the carets. The
branch's entire contribution to Cargo.lock versus f364d065 is two lines:

 name = "dig-node-service"   -version = "0.152.0"  +version = "0.153.0"
 name = "dig-wallet"         -version = "0.34.0"   +version = "0.35.0"

Zero dependency version lines moved. chia-query resolves to 0.6.2 on both sides and is
declared identically at crates/dig-wallet/Cargo.toml:94 on both sides; dig-node-core is 0.57.2
on both sides, so the conflict really was resolved to main's value, twice. The only manifests in the
delta are Cargo.toml (workspace 0.153.0) and crates/dig-wallet/Cargo.toml (0.35.0).
Nothing this audit or the previous three rested on can re-resolve. I also diffed the branch's
whole pre-rebase contribution (dffb264..836de62) against its post-rebase contribution
(f364d065..3e026a8): the only content differences are those two version bumps, hunk-offset shifts
in SPEC.md, and the sources.rs growth that is the fix. The rebase moved nothing else.

The 5-blind-files retraction is correct — confirmed independently. I recovered the pre-fix
classifier with git show b0e5fb1:crates/dig-wallet/src/sage/sources.rs, extracted brace_balance
and production_lines verbatim with sed (both arms present, including the one_liner_ended arm the
lane had dropped), and walked the real tree:

files scanned: 38
PRE-FIX blind files (5): ["autoseed.rs", "rpc.rs", "tipping.rs", "types.rs", "watchlist.rs"]

Exactly the retracted list. peer_reads.rs was never blind, so the corroborated-peak path was
never exposed. The shipped docs say five in three places (:463, :486, :696) and name the right
five at :627-628 — the durable artifact was always accurate; only the earlier PR comment
overstated, and it has been retracted on the record.

Baseline reproduced independently, every gate UNPIPED, read from the test result: line.

cargo test -p dig-wallet --lib                             EXIT=0
   test result: ok. 655 passed; 0 failed; 1 ignored; 0 measured; 0 filtered out
cargo fmt --all -- --check                                 EXIT=0  (zero output)
cargo clippy -p dig-wallet --lib --tests -- -D warnings    EXIT=0  (zero error/warning lines)

The single ignored test is pre-existing on MAIN, not introduced here.
sage::sync_supervisor::tests::live_mainnet_default_install_corroborates_and_follows_the_chain, the
only #[ignore] in the crate. Byte-identity by blob hash rather than by an empty diff —
6e8b751972705fd48a1caefa4c9c035046b03756 at 41577001, 836de62, 3e026a8 and f364d065.
Nothing was ignored to make this suite green.

Custody, secrets, dependencies, exposure. No key, seed or signing capability touched. No
credential, token, .test-credentials value or projectId added, logged or printed. No new endpoint,
RPC, permission or remote entry point — nothing in the delta is reachable by any peer, so the authz
and amplification questions do not arise for it. No pin loosened: the only .toml/.lock lines in
the delta are the two version bumps above. Version-increment gate satisfied (0.153.0 over main's
0.152.0; dig-wallet 0.35.0 over 0.34.0; manifest and lock agree).

All 15 required checks report SUCCESS at this head (one SKIPPED: "Attach packages to the
release"), mergeable: MERGEABLE, still DRAFT — correctly, since a gate round was in flight.


NON-GATING (do not hold the merge on these)

  1. The new fixture's flag assertion is non-discriminating for the acceptance revert — the flag is
    false in both the fixed and the reverted state, so only the sites assertion fires. Correct as
    documentation; not a second independent proof.
  2. :758's "nothing was invisible" overstates what unread.is_empty() delivers, which is only
    no file ran out of text while latched. Folded into remedy 4 above.
  3. an_indented_cfg_test_does_not_blind_the_sweep and
    a_stray_brace_in_a_test_fixture_does_not_hide_the_production_code_below_it still discard the
    flag
    — round 3's non-gating note, unchanged, still harmless.
  4. dig-gossip v0.25.0 resolves from a git source, not crates.io (NC-7). Pre-existing on main,
    untouched by this delta, out of scope for this re-gate — noted only so it is not lost.

Verification hygiene

Everything ran in my own worktree, C:/tmp/worktrees/sec354r4, cut with
git worktree add --detach at 3e026a8. Final state:
HEAD=3e026a8d18953d58d6ecd07ceab1e43ab19431e9, git status --porcelain empty, git clean -nd
empty, no local commits, no stash created by me (the three present are pre-existing and belong to
other branches). Two source mutations — the acceptance revert and the trailing-comment probe test —
were applied there, measured, then restored from a pristine copy taken before each; both restorations
verified against the HEAD blob.

The shared dig-node checkout was never mutated — no checkout, reset, stash or edit; all PR content
read via git show, git diff, git rev-parse and gh.
C:/Users/micha/workspace/dig_network/worktrees/dig-node-2790 and C:/tmp/worktrees/fix354 were not
touched, and no target/ outside my own worktree was deleted. One cargo process at a time. Disk
stayed at 199 GB free. I did not merge, undraft, or edit any code on this PR.

Round-4 finding fixed, doc-only — head c5aad53

loop/2790-nc12-registry. mergeable=MERGEABLE, still DRAFT. Suite 655 passed / 0 failed / 1 ignored, cargo fmt --all --check clean, cargo clippy -p dig-wallet --lib --tests clean (0 errors). No production code changed and no fourth heuristic was added — I took your instruction literally.

What I measured before writing a word

Four shapes probed against the real compiled sweep, in-crate, probe removed afterwards:

PROBE attr-on-its-own-line then one-line item with ctor:        sites=[2, 3] flag=false
PROBE attr INLINE with the item, ctor on it:                    sites=[2]    flag=false
PROBE commented terminator, MULTI-LINE production fn below:     sites=[]     flag=false
PROBE bare terminator control, MULTI-LINE production fn below:  sites=[5]    flag=false
PROBE string-content attribute at column 0:                     sites=[7]    flag=false

Your commented-terminator finding reproduces exactly — sites=[] against a control of sites=[5], flag false in both.

The three false statements

:501 — the worked example was backwards, and you were right to say correct this one above all. #[cfg(test)] fn f() { ChiaQuery::new(c); } measures sites=[2], i.e. the construction on that line is dropped, because a latching line is never passed to ends_a_column_0_item. The doc claimed it fails loudly. Both forms are now stated with their measurements: the loud case is the attribute on its own line with the item below (sites=[2, 3]), and the attribute-inline form drops the construction as the test code it genuinely is — correct behaviour that the doc had described as its opposite.

:508 — "The one shape that IS silent" is now "The shapes that are SILENT — two known today, and the list is open", naming both with directions: string-content #[cfg(test)] at column 0, and a terminator carrying trailing content, with the sites=[5] vs sites=[] measurement and the rustfmt-preserves-it note.

:26 — "names every shape it mis-reads" is now "names the mis-read shapes KNOWN TODAY", followed by: "That list is open, not exhaustive — four rounds of review found four shapes, each invisible to the fixture written for the one before it, so assume a fifth exists rather than reading the list as a proof." The sweep header lost its "every imprecision fails LOUDLY" claim for the same reason; it now says loudly wherever that is achievable without parsing, and points at the two where it is not.

One thing the probe added that the finding did not

Both silent shapes are bounded, and the doc now says so. A mis-latch lasts only until the next column-0 line ending in } or ; — the end of the next item in ordinary Rust — so each drops the constructors inside that window, not everything to EOF. That is what makes these materially less severe than the brace-counting classifier they replaced, which went blind to EOF in five files simultaneously. It is stated as a bound on the damage, not as a reason to leave them.

Visible in the string-content probe above: sites=[7] — the false latch set at line 3 cleared at line 5 and the production site at 7 was still reported. That shape is only silent when a constructor falls inside the window.

Non-gating: the flag assertion

Taken. The round-3 fixture's !ended_inside_a_test_item assertion now carries a comment saying it documents rather than catches — false in both states, because the shape's whole point is that the flag stays quiet while the sweep goes blind — and that the site assertion above it is what fails on a revert.

Rebase and version

Re-checked, as instructed. origin/main is still f364d065 and the branch is already rebased onto it (git merge-base --is-ancestor origin/main HEAD passes); the dig-app and dig-keystore merges are other repos. Versions still clear main: workspace 0.153.0 vs main's 0.152.0, dig-wallet 0.35.0 vs 0.34.0. No rebase performed because none was needed — say the word if you would rather I rebase anyway once main moves before merge.

Standing: round-1 items 4, 7, 8 with the orchestrator; item 5 on dig-node#360; chia-query#38 open.

CHANGES-REQUIRED — round 5, doc-only scope

Head reviewed: c5aad5338ec334119643b52f0642ff9cfd4a9bb3 (resolved from the remote at audit time, not taken from the dispatch).

Recorded as a COMMENT review: a verdict-bearing event is HTTP 422 on a same-identity PR. The open inline thread below is what bars the merge.

What I verified, by measurement rather than by reading the prose

Diff 3e026a8d..c5aad533 is one file, +40/-16, doc plus one test comment - zero production lines. Confirmed.

I re-ran every inline number in the doc against the real compiled sweep, via probes appended to mod sole_owner_tests in my own worktree:

doc claim measured
:501 attr on its OWN line, one-line item + ctor, production line below -> sites=[2, 3] sites=[2, 3] flag=false PASS
:501 attr INLINE with the item, ctor on it -> sites=[2], construction dropped sites=[2] flag=false PASS
:508 bare terminator control -> sites=[5] sites=[5] flag=false PASS
:508 } // done terminator -> sites=[] sites=[] flag=false PASS
string-content attribute, bound evidence -> sites=[7] sites=[7] flag=false PASS

The :508 control pair genuinely discriminates - bare terminator reports the production site, commented terminator reports nothing, on the identical fixture. The :501 correction is now the right way round: the inline-attribute form latches on its own line, and a latching line is never passed to ends_a_column_0_item, so its construction is correctly dropped as test code.

:26 - the retraction is a real sweep, not a spot edit. grep -n "LOUDLY" over the file returns one hit, the qualified form at :494 ("fail LOUDLY wherever that is achievable without parsing"). The unqualified "every imprecision fails LOUDLY" survives nowhere.

The new bound claim holds. The mis-latch does clear, and the site after the window is still reported. Better than the doc states: the truly-unbounded case is LOUD - sites=[] flag=true, the refusal fires. One sizing caveat in a non-gating note below.

Gates, re-measured at this head

  • cargo test -p dig-wallet --lib -> test result: ok. 655 passed; 0 failed; 1 ignored (parsed from the test result: line, run unpiped). Reproduces the stated baseline exactly.
  • cargo fmt --all --check -> RC 0. cargo clippy -p dig-wallet --lib --all-features -> 0 errors.
  • check-merge-preconditions.sh -> all five required contexts SUCCESS by name (Lint commit messages, Check version increment, Rustfmt, Clippy, Test + coverage), unresolvedReviewThreads=0, mergeStateStatus=CLEAN, BLOCKED on draft=true alone -> GREEN-BUT-DRAFT.
  • Rebase/version re-measured myself: origin/main = f364d065, git merge-base --is-ancestor origin/main HEAD passes, workspace 0.153.0 vs 0.152.0, dig-wallet 0.35.0 vs 0.34.0. All current.

The one gating finding

A comment ADDED in this round claims a live assertion is non-discriminating. It is not - measured flag=true under the revert the test is named for. Detail and reproduction are in the inline thread. It is a small, precise fix, and it must not be "fixed" by deleting the assertion.

Everything else in this round's doc delta is true as written.

Fixed in b32d523. You are right, and I re-measured both reverts myself rather than relaying yours:

revert A -- require a BARE `}` again (the fix this test is named for):  sites=[]  flag=true
revert B -- `continue` past the clearing line instead of judging it:    sites=[4] flag=false

So the assertion FIRES under revert A — the one this test is named for, and the one my own doc at :674-676 describes. My claim was true only of B, which is the narrower reading, and I wrote it as though it covered both.

The comment now names which revert is which, carries both measurements inline (the standard every other claim in this file already meets), and records WHY the correction exists: a comment that calls a working assertion "documentation" is how a working assertion gets deleted. The assertion itself is untouched.

Also took the non-gating note. "Bounded" now says explicitly that it is not the same as small — a false latch on string content nested in an impl holds for the whole block, 40 constructors in your 130-line fixture — and adds the point your measurement makes better than mine did: the genuinely unbounded case is the LOUD one, because a latch that never clears reaches EOF and the refusal fires. What is silent is bounded; what is unbounded is not silent.

…fabric

NC-12 asks that no path construct its own peer fabric outside the registry.
That clause held for the worst possible reason: there was no registry.
`ProviderRegistry` had no production construction site in dig-node, so the
property was satisfied by the absence of the thing it governs.

`NodeChainSources` is now the sole production caller of `ChiaQuery::new`, and
it registers what it built: the node's own peers ahead of the public oracle, in
separate independence groups, both untrusted, with public-quorum custody off so
the custody view fails closed on a default install.

Refs: DIG-Network/dig_ecosystem#2790
A revert-proof run showed all three tests failing on the VALUE assertion, so
the assertion that pins the oracle out of the path was never evaluated and
proved nothing. Reordered, the same revert fails each test on the placement
assertion by its own message.

Refs: DIG-Network/dig_ecosystem#2790
Also bumps the workspace to 0.151.0 and dig-wallet to 0.34.0: a compatible new
capability, with one behaviour change on a chain read that a caller can only
observe as an honest unknown where it previously got a third party's number.

Refs: DIG-Network/dig_ecosystem#2790
The rebase onto main silently absorbed the earlier bump: dig-node#344 landed
0.151.0 / 0.34.0, the exact values this branch had written, so both sides wrote
something plausible and git resolved it with no conflict. The increment gate
caught it, not a reviewer.

Refs: DIG-Network/dig_ecosystem#2790
The `in_tests` latch tripped on the FIRST `#[cfg(test)]` anywhere in a file
and never cleared. chain.rs gates a test helper inside `impl ChainTransport`
at line 157, so lines 158-711 — `peak_height()`, `push()`, the
`ChainFallback` impl — were invisible to the sweep, and a live second peer
fabric compiled into `ChainTransport::peak_height` left the guard green.

Latch only on a column-0 attribute, and clear the latch when the item it
introduced ends. Documented as the heuristic it is, with each imprecision's
failure direction named. Two fixture tests pin the classification.

… type

`ChiaQueryProvider` reads through chia-query's router, whose first act is
"try coinset first for full state" with `coinset_fallback_enabled: true` in
the default config the fabric is built from. Registering it as its own
independence group made a 2-of-2 independent-group custody quorum satisfiable
by one HTTPS endpoint: measured on a `max_peers: 0` client — a node holding
no peers at all — the custody view returned a peak.

Derive the group from the config the fabric was built with, so a fabric that
can fall through to the oracle shares the oracle's group and only a
peers-only fabric counts as independent. A client handed in from outside
describes nothing about what it can reach and is grouped conservatively.

Corrects the two module doc claims the code contradicted.

Co-Authored-By: Claude <noreply@anthropic.com>
…onal one

"it never leads it" was stated without qualification and is false: eligible
keeps claims within PEAK_LAG_TOLERANCE of their own MEDIAN, so claimants who
are a majority of those who answered own the band, evict the honest claims
and place the result where they like — measured leads of +998 and +498.

State the weaker true property: the result is the MINIMUM of the credible
claims, so it cannot lead the tip while any credible claim is honest. Pinned
from both sides — an outvoted liar cannot move it, a colluding majority can.

Also record that settled_peak runs on the QUORUM_SAMPLE-wide held sample and
never calls hold_best, so band_kept_a_majority's 6-of-10 table describes a
different path; and restore common_height's doc comment, which the settled_peak
block had been inserted in front of.

…literals

The latch cleared on brace BALANCE, and `brace_balance` counted braces inside
string literals. The crate's ordinary malformed-JSON fixture — `"{ not json"`
at rpc.rs:8233 and four more — left the balance permanently positive, so five
of 38 files were blind from their first column-0 `#[cfg(test)]` to EOF. A
column-0 production fn appended to rpc.rs passed the sweep.

Clear on the next column-0 item end instead: a bare `}` or a `;` at column 0.
Literal content is almost always indented, so refusing to look at it is both
simpler and stricter than parsing it out.

The sweep now also reports when it ran out of text still inside a
`#[cfg(test)]` item, and the assertion REFUSES on such a file. When the
classifier cannot tell, it says so rather than returning an empty stray list
that reads identically to a clean file.

The regression test's fixture is widened to carry the unbalanced brace inside
a string; the balanced one could not express the shape at all.

…stry

The module doc claimed the registry was LOAD-BEARING and that its custody view
refuses "on a default install", which reads as a gate in a live path. It is
not one: NodeChainSources::registry() has no production caller — ChainTransport
asks only for client(), and nothing calls trusted() or any().

NC-12 clause 3's "Satisfied by" record gets written from this module doc, so
an overstatement here becomes the ecosystem's record of a discharged
obligation. State the true, weaker thing: the sole-owner sweep is the
enforcement, the registry gives that sweep its target, the classification is a
correct inventory awaiting its first consumer, and the read that genuinely
removed the third party is the corroborated peak next door.

Co-Authored-By: Claude <noreply@anthropic.com>
ends_a_column_0_item cleared only on a line that IS `}`, so a column-0 item
written on one line — `fn helper() {}`, `mod probe {}`, `impl X {}` — never
cleared the latch. That shape defeated both of the previous round's remedies at
once: the sweep went blind for the rest of the file AND ended_inside_a_test_item
stayed false, so nothing reported it. rustfmt preserves such one-liners, so
cargo fmt does not suppress it. No file in this crate has the shape today.

Accept any column-0 line ending in `}` or `;`, and judge the clearing line like
any other line, so a constructor written ON a one-line test item is reported as
production rather than vanishing with the line that cleared the latch.

Bound the three sentences that claimed the sweep catches a second fabric
"anywhere in this crate": a green means no VISIBLE second owner and nothing
invisible, which is the strongest claim a source sweep can make. The one
remaining silent shape — a column-0 `#[cfg(test)]` as string content — is named
with its failure direction rather than left out.

Co-Authored-By: Claude <noreply@anthropic.com>
… complete

Three statements were measurably false, and the worked example was backwards.

The sweep doc claimed every imprecision fails loudly and that one shape is
silent. Two are: a column-0 `#[cfg(test)]` appearing as string content, and a
terminator carrying trailing content (`}  // done`), which ends_a_column_0_item
does not recognise because it judges the raw line. Measured: the same fixture
gives sites=[5] with a bare `}` and sites=[] with the comment, flag false in
both. rustfmt preserves the trailing comment.

The one-line-item bullet claimed `#[cfg(test)] fn f() { ChiaQuery::new(c); }`
fails loudly. It does not — a latching line is never passed to
ends_a_column_0_item, so that construction is dropped as the test code it is.
The loud case is the attribute on its own line with the item below, measured
sites=[2, 3]. Both forms are now stated with their measurements.

No fourth heuristic. Four rounds found four shapes, each invisible to the
fixture written for the one before it, so the list is documented as OPEN and
the module doc no longer implies otherwise. What bounds the damage is stated:
a mis-latch lasts only to the next column-0 terminator, not to EOF.

Also notes that the one-line fixture's flag assertion documents rather than
catches — it is false in both states.

Co-Authored-By: Claude <noreply@anthropic.com>
…mentation

The comment added last round said ended_inside_a_test_item is false before and
after the one-line-item fix and that the assertion documents rather than
catches. That is true only of the narrower revert.

Measured on that fixture against the compiled sweep:

  revert A (require a bare } again, the fix this test is named for): sites=[] flag=true
  revert B (continue past the clearing line):                        sites=[4] flag=false

Under A the assertion FIRES — the latch never clears, the sweep reaches EOF
still inside the test item, and the fail-closed flag is what says so. Both
measurements now sit inline, which is the standard every other claim in this
file already meets.

A comment that calls a working assertion documentation is how a working
assertion gets deleted, so the correction is recorded rather than just applied.

Also: bounded is not small. A false latch on string content nested in an impl
holds for the whole block — 40 constructors dropped in a 130-line fixture — and
the genuinely unbounded case is the loud one, since a latch that never clears
reaches EOF and the refusal fires.

main took 0.153.0 independently (PR#362), so the branch's own 0.153.0 bump was
dropped by the rebase as already upstream and the version stopped incrementing.
dig-wallet stays 0.35.0, above main's 0.34.0; dig-node-core is main's 0.58.0.

Third time this branch's bump has gone stale across a gate round — re-check
against origin/main before every push, not only at open.

Round-5 finding fixed, thread resolved — head b1d33818

loop/2790-nc12-registry, rebased onto the NEW main (07456b94). Still DRAFT.

draft=true  mergeStateStatus=CLEAN  unresolvedReviewThreads=0
  Lint commit messages    SUCCESS      Check version increment  SUCCESS
  Rustfmt                 SUCCESS      Clippy                   SUCCESS
  Test + coverage         SUCCESS

All five required contexts asserted BY NAME via check-merge-preconditions.sh. Local: 655 passed / 0 failed / 1 ignored, cargo fmt --all --check clean, clippy 0 errors, cargo check -p dig-node-core clean on the new base.

The comment — b32d523

You are right, and I re-measured both reverts rather than relaying yours:

revert A -- require a BARE `}` again (the fix this test is named for):  sites=[]  flag=true
revert B -- `continue` past the clearing line instead of judging it:    sites=[4] flag=false

Revert A makes the site assertion fire first, so I probed the flag directly under A to see it: PROBE sites=[] flag=true. The assertion is live under the revert this test is named for — the one my own doc at :674-676 describes. My claim was true only of B, and I wrote it as though it covered both.

The comment now names which revert is which, carries both measurements inline, and records why the correction exists rather than just applying it. The assertion is untouched. Thread PRRT_kwDOTHG0ds6cKbM6 resolved with the measurements on it.

That this slipped past the house style in the same round that established it is the more useful finding: the standard held for every claim about the code and lapsed on the one claim about a test.

Non-gating taken

"Bounded" now says explicitly it does not mean small — a false latch on string content nested in an impl holds for the whole block, 40 constructors in your 130-line fixture — and it adds the point your measurement makes better than my original did:

The genuinely unbounded case is the LOUD one: a latch that never clears at all reaches EOF, which is precisely what ended_inside_a_test_item reports and the assertion refuses on. What is silent is bounded; what is unbounded is not silent.

Rebase — and the version bit for the third time, differently

main moved to 07456b94 (PR#362) during this round, and it took workspace 0.153.0 independently. The rebase therefore dropped my own 0.153.0 bump as "already upstream", leaving the branch level with main and the increment gate about to fail — a different mechanism from the previous two times, and one that produces no conflict and no red until the gate runs.

Bumped to 0.154.0, dig-node-service re-locked; dig-wallet stays 0.35.0 above main's 0.34.0; dig-node-core is main's 0.58.0. Check version increment is SUCCESS on the new head. Suite re-run on the new base, not assumed.

Worth a repo-level note: a rebase silently dropping a version bump is invisible to git status, to the diff, and to every local gate. The lane rule I am adopting is to re-read origin/main's version immediately after every rebase, not only before every push.

The version-increment gate held both numbers and reported only pass/fail. A
stale bump is invisible everywhere else -- `git status`, the diff, fmt, clippy
and the test suite are all green when `main` has taken your version number, and
a rebase can drop the bump commit entirely as "already upstream". It went stale
three times on one branch (PR #354) across a five-round gate, and each time the
lane had to rediscover at merge what the comparison even was.

Writes a table to `$GITHUB_STEP_SUMMARY` on EVERY run, success or failure: the
base ref actually compared (short SHA of `main`, plus the head SHA), a row per
manifest with base, head and verdict, the must-match row where both exist, and
the overall verdict spelled out. Being able to READ the comparison while the
gate is green is the point -- that is what turns a merge-time surprise into
something a long-lived review round can notice.

What the gate ENFORCES is unchanged: same predicate, same exit code, same error
annotations. `${GITHUB_STEP_SUMMARY:-/dev/null}` keeps the script runnable off
Actions, which is how the three cases below were exercised.

Bounded to dig-node deliberately (#364, CLAUDE.md 1.3c rule zero). 25 other
repos carry a byte-identical copy and 6 carry a diverged one; propagating is a
named follow-up with that finite list, not "every repo".

Verified by running the extracted script unpiped against scratch repos:
passing (RC=0), the stale-bump failure with `main` holding the same version
(RC=1), and the both-manifests-agree case (RC=0) -- each producing its summary.

Closes #364

…, executed sweep examples (#368)

* chore(wip): batch #360 #361 #363 #364 #367 — stub for lane ownership

Co-Authored-By: Claude <noreply@anthropic.com>

* refactor(wallet): delete the dead oracle-first ChainTransport constructor

`ChainTransport::with_sources` had no callers anywhere in the workspace, was
`pub` + `#[must_use]`, and built `peer_reads: None` — a transport whose
`peak_height` takes `chia-query`'s router path, which asks `api.coinset.org`
FIRST. It read like the obvious way to build a transport over the node's own
fabric while quietly being the one shape NC-12 exists to prevent: the node's
headline chain fact decided by a single third party.

Deleted rather than repaired: a constructor kept "in case someone needs it" is
how it comes back, and the only production construction
(`sage/service.rs:173`) already chains `with_peer_reads`.

Makes the deletion durable with a fail-closed source guard: the constructors
that may build `peer_reads: None` are a CLOSED enumeration of two (`new`, and
the `#[cfg(test)]` `with_client`), and a third one fails the suite by name.
Proved load-bearing by reintroducing `with_sources` — the guard reports it.

Closes #360

* fix(test): stop the serve harness leaking a ~57 MB temp tree per node

`content_serve.rs` built its temp path by hand -- `env::temp_dir().join(format!
("dig-node-serve-test-{pid}-{n}"))` -- and nothing ever removed it. Each node
seeds a real compiled `.dig` module and warms a cache, so a run cost ~57 MB per
node. 1,123 trees reached 62.5 GB and took the dev machine to 81 MB free on a
1.9 TB disk, producing a machine-wide ENOSPC that stopped an unrelated lane
mid-build. It is self-concealing: it grows fastest when the suite runs most, so
it reads like a build-cache problem (the first diagnosis blamed worktree
`target/` dirs, which were not the cause).

- A `NodeCache` RAII guard OWNS the tree (`tempfile::TempDir`), so removal
  happens in `Drop` -- including on an unwind. Ownership is the point, not the
  deletion: a cleanup line at the end of a test is skipped by every failing
  assertion, i.e. exactly the runs a developer repeats.
- Both leaking sites in the file are covered (`dig-node-serve-test-*` and
  `dig-node-origin-test-*`); the latter now shares the guard.
- The node's detached axum task still holds `wallet.sqlite` open when the test
  body returns, and Windows will not unlink an open file, so `TempDir::drop`
  cannot remove that last ~1 MB. `Drop` cannot cancel the task (it cannot
  `.await`), so the residue is BOUNDED rather than pretended away: a once-per-
  process sweep removes trees idle for 15 minutes, which no live run can be.

Measured, same machine, full suite: per-run residue 970 MB -> 17 MB, and the
62.5 GB accumulation is gone. Two tests hold it: one asserts the tree is gone
after a normal drop AND after a `catch_unwind` panic; one asserts the sweep
removes an abandoned tree while sparing a live one and a stranger's directory.
Each was proved load-bearing by reverting only its own fix.

Closes #361

* ci: report the version comparison the gate made, on every run

The version-increment gate held both numbers and reported only pass/fail. A
stale bump is invisible everywhere else -- `git status`, the diff, fmt, clippy
and the test suite are all green when `main` has taken your version number, and
a rebase can drop the bump commit entirely as "already upstream". It went stale
three times on one branch (PR #354) across a five-round gate, and each time the
lane had to rediscover at merge what the comparison even was.

Writes a table to `$GITHUB_STEP_SUMMARY` on EVERY run, success or failure: the
base ref actually compared (short SHA of `main`, plus the head SHA), a row per

the overall verdict spelled out. Being able to READ the comparison while the
gate is green is the point -- that is what turns a merge-time surprise into

* test(wallet): execute the sweep guard's worked examples instead of asserting them

A doc example in `sources.rs` was exactly backwards -- it claimed the
attribute-inline shape failed loudly, when it measures `sites=[2]` and drops the
construction -- and it survived FOUR adversarial gate rounds. Everything else in
that file was measured; only the examples were prose, and that is where the
false statement lived. Reviewers read a doc example as documentation rather than
as a claim to test, so the remedy is to make the claim executable.

The worked examples are now `json` blocks carrying their fixture AND their
expected `sites` / `ended_inside_a_test_item`, and a test extracts every one of
them from this file's own source and runs the real classifier over it.

Doing this as a rustdoc doctest is not possible and would have been worse than
prose: rustdoc does not run doctests on `#[cfg(test)]` items, and this whole
module is one, so a ```rust example would compile in nobody's build while
reading exactly like a passing test.

Fail-closed twice over: an unterminated block is an error, and the example COUNT
is pinned, so deleting an inconvenient example -- the cheapest way to green --
fails rather than passing quietly.

Found while doing it: the trailing-comment example asserted `sites=[5]` and
`sites=[]` for "the same fixture" WITHOUT ever writing that fixture down, so its
numbers were unreproducible by construction. The fixture is now explicit and the
measured values are `[6]` and `[]`. A claim whose input is missing cannot be
checked by anyone, which is worse than a claim that is merely wrong.

No classifier heuristic is added. Five rounds established that the durable
artifact is the fail-closed flag plus an honestly open enumeration, and `sweep`
is untouched -- only the file's statements ABOUT it are now enforced.

Each of the four examples was proved load-bearing: altering any expected value,
and flipping any documented flag, turns the suite red naming that example.

Closes #363

* chore(wallet): bump dig-wallet to 0.36.0 for the removed pub constructor

`ChainTransport::with_sources` was `pub`, so deleting it is a breaking change to
this crate's surface even though it had no callers. SemVer minor on 0.x.
