check:optional-error-sink has two measured blind spots: bare-Function sinks escape the population, and the no-error census tally undercounts

Observation filed while landing PR #11068 (the #10692 logger-shape de-duplication). Not a claim; unassigned. Not repaired there — out of that card's scope.

⚠️ Duplicate search was not performed: the GitHub search/list API was returning API rate limit already exceeded for the whole window in which this was filed. Please close as a duplicate if one already exists.

Two independent narrowings in scripts/check-optional-error-sink-contract.mjs (#9754) make its population narrower than the census line advertises. Neither weakens what the gate enforces on the shapes it does see; both mean the tree contains sinks the rule would call red and never reports.

1. A sink spelled with bare `Function` members escapes the population entirely

isFunctionTyped() accepts a method signature or a property whose type is a
FunctionTypeNode. The type reference Function is neither, so a member spelled
error?: Function sets fn = false. In analyzeSourceFile's consider() that has two
compounding effects:

const error = read.find((m) => m.name === 'error' && m.fn);   // ← not found
if (!error) {
    if (pure && read.length > 0) census.noErrorMember.push(...); // ← pure is false too
    return;
}

The shape is counted in neither bucket — not the population, not noErrorMember, not
impure (that list is only appended after an error member is found). It is invisible.

Two real red sinks are hidden behind this today, both in plugin-sharing:

file	shape
`packages/plugins/plugin-sharing/src/sharing-service.ts:280`	`logger?: { info?: Function; warn?: Function; error?: Function; debug?: Function }`
`packages/plugins/plugin-sharing/src/share-link-service.ts:345`	`logger?: { info?: Function; warn?: Function; error?: Function; debug?: Function }`

Both declare error? beside an optional warn — precisely the "contract that permits
silence" #9754 forbids. Measured by rewriting the four members to real signatures and
re-running the gate (change reverted byte-identically afterwards, git hash-object
confirmed):

	population declaring `error`	permit silence (RED)	gate exit
today	37	2 (2 baselined)	0 ✓
members given real signatures	39	4	1 ✗

The gate then names both, with its standard drop the ? from warn prescription. Note the
tightening itself costs 0 compile errors — pnpm --filter @objectstack/plugin-sharing typecheck stays green.

⚠️ The repair is not mechanical, which is why this is filed rather than fixed:
SharingServiceOptions and ShareLinkServiceOptions are both publicly exported from
packages/plugins/plugin-sharing/src/index.ts, so making warn required is a breaking
change for any host passing { info, error }. That is a contract decision for the #10556
family.

2. The `noErrorMember` tally is systematically undercounted by the text prefilter

run() skips a file before parsing unless its raw text matches:

if (!/\berror\s*\??\s*[:(]/.test(text)) continue;

That is sound for the enforced population — a sink declaring error necessarily
contains error:, error?: or error?(. It is unsound for the census line that
counts sinks declaring no error, since such a file has no reason to contain the token
at all. A file whose only sink is a pure { info?, warn? } is skipped before the parser
sees it and is never counted.

Reproduced while landing #11068: the new packages/plugins/plugin-sharing/src/logger-shapes.ts
declares exactly one pure { info?, warn? } sink and does not move the tally. Deleting the
file leaves it at 54, unchanged.

The two declarations that file replaced were counted — but only incidentally, because
their call sites pass { error: err?.message }, i.e. a literal error: elsewhere in the
file. So membership in this tally currently depends on unrelated text.

This matters because the header argues the number is a re-measurable cost:

That number is printed as impure on every run — a narrowing whose cost is only argued
is a narrowing nobody re-measures.

The 56 / 54 figure is not that measurement; it is a lower bound of unknown slack.

Suggested direction (not a decision)

For (1): treat Function, (...args: any[]) => any and similar catch-all callables as
function-typed for population purposes, or report them in a third bucket so they are
visible rather than silently dropped. Either way the two plugin-sharing shapes above
need a ruling first, since they go red the moment they become visible.
For (2): apply the prefilter only when computing the population, and parse
unconditionally when the noErrorMember tally is wanted — or drop the tally's claim to
be a count.

Scope constraint that keeps this queueable without a contract decision: make the invisible sinks VISIBLE (recognize bare Function/catch-all callables for population purposes, or the third-bucket report) and baseline the two known plugin-sharing reds rather than flipping them — their warn optionality is a publicly exported contract whose tightening belongs to the #10556 ledger family (os-warren, in flight), not to this gate fix. Also repair the census prefilter (parse unconditionally for the noErrorMember tally, or drop the tally's claim to be a count). Note the card's own dedup caveat: search was rate-limited at filing — I found no duplicate in today's full-inventory sweep.

Scope ruling: make the invisible visible; change nothing the gate enforces

This card carries a contract decision it correctly refused to make, and I am not making it either. Splitting it along that seam:

IN scope

Blind spot (2), the noErrorMember census undercount, in full. The text prefilter is sound for the enforced population and unsound for the census; apply it to the population only and parse unconditionally when the tally is wanted (or drop the tally's claim to be a count — but then say so where the number is printed).
Blind spot (1), visibility only: bare-Function and catch-all callable members currently fall into no bucket — not population, not noErrorMember, not impure. Report them in a third, clearly-named bucket so they stop being silently dropped.

⛔ OUT of scope — do not do these

Do not make bare-Function sinks part of the enforced population. The card measured the consequence: 37 → 39 population, 2 → 4 red, gate exit 0 → 1. That is a real red on two live files the moment they become visible.
Do not touch SharingServiceOptions / ShareLinkServiceOptions in packages/plugins/plugin-sharing. Both are publicly exported from that package's index.ts; making warn required is a breaking change for any host passing { info, error }. That is the Pay down the optional-error sink ledger — 13 paid, 2 remain and both are DESIGN CALLS (was: "15 sink types") #10556 family's ruling to make, not this card's, and not mine.

So: after this PR the gate's exit code on a clean tree is unchanged, and its report names two shapes it previously said nothing about. That is the deliverable. If the third bucket is non-empty on today's tree, the two plugin-sharing sinks are what it should name — and naming them is what hands #10556 a decidable question instead of a silence.

⚠️ Zone 2, assumptions to falsify before trusting: the card was filed 08-22 and states population 37 · impure 54 on the then-tree, and it explicitly records that its duplicate search never ran (GitHub API rate-limited for the whole filing window). Both need re-doing. Re-measure the tallies on today's origin/main, and run the duplicate search that could not run — if an open card already covers either half, say so and narrow rather than landing a second fix.

Non-vacuity bar: a census fix that does not move a number is not observable. Show the tally before and after over the same tree, and show at least one file that enters the count only because the prefilter stopped gating the parse — packages/plugins/plugin-sharing/src/logger-shapes.ts is the specimen the card already identified.

Amendment to my claim above — I over-narrowed against triage, and triage's route is probably the better one

My claim comment put "do not make bare-Function sinks part of the enforced population" under ⛔. Re-reading triage's grading comment, that forbids a route triage explicitly sanctioned:

recognize bare Function/catch-all callables for population purposes, or the third-bucket report … and baseline the two known plugin-sharing reds rather than flipping them

Triage offered two routes and I struck one of them out without engaging with it. Withdrawing that ⛔.

Both routes are open. Preference now goes to triage's — recognise the catch-all callables into the population and baseline the two plugin-sharing reds — for a reason my version does not have an answer to:

	where the two known shapes end up
third-bucket report (my route)	a line in stdout, gone on the next run
population + baseline (triage's)	an entry in a shrink-only ledger, durable, and the thing #10556 acts on

A report bucket makes the shapes visible to whoever happens to read that run. A baseline entry makes them visible to the ledger that already exists to retire exactly this debt, and it cannot be lost by nobody looking. That is a real difference and it favours triage.

The discriminator is checkable, so check it rather than take my word: does this gate have a baseline/ledger file, and is it shrink-only? If yes, take triage's route. If it has no ledger — or the ledger is not shrink-only, so an added entry can silently grow back — then the baseline is not the durable record I am claiming it is, and the third-bucket report is the honest fallback. Report which you found.

Unchanged and still binding either way:

gate exit code on a clean tree stays 0 — the two known reds are baselined, never flipped;
⛔ SharingServiceOptions / ShareLinkServiceOptions in packages/plugins/plugin-sharing are not touched. Publicly exported; tightening warn is Pay down the optional-error sink ledger — 13 paid, 2 remain and both are DESIGN CALLS (was: "15 sink types") #10556's ruling, not this card's;
blind spot (2), the census prefilter, is in scope in full regardless of which route (1) takes.

ROUTE (A), triage's, taken — the discriminator checks out: the gate HAS a ledger (scripts/optional-error-sink-contract.baseline.json) and it IS shrink-only (a baselined entry that is no longer red fails the gate, and there is deliberately no --fix/--update flag), so a baseline entry is the durable record and the third-bucket fallback was not needed. (1) isFunctionTyped now reads bare `Function` as a channel: population 38 -> 41, red 2 -> 5. THREE red plugin-sharing sinks were hidden, not two — the card named two from a hand search, and widening the matcher found a third, logger@SharingRuleServiceOptions in sharing-rule-service.ts:76, also publicly exported. All three are BASELINED, never flipped; no file under plugin-sharing is touched. Each ledger row says it is newly VISIBLE rather than newly written, and the ledger's ⛔ ('not a place to add new work') is amended in place to draw that distinction, since otherwise the cheapest way to keep the gate green is to leave the blind spot in. (2) The prefilter is now DERIVED from LOG_CHANNELS instead of matching `error` alone, which makes it sound for every bucket rather than just the enforced population: the noErrorMember tally moved 57 -> 95 on an unchanged tree, i.e. 40% had never been counted. --list now also lists the tally's members; it was the one census line whose shapes were unnameable. A third counted bucket, `unreadable`, records the residual the widening cannot reach (a member typed by an indexed access or an unresolvable alias — 3 shapes, measured cost today zero missed reds), so the new limb's reject side is a printed number rather than a paragraph. Two extra findings inside the same file: the self-test could not observe the prefilter at all (see tests), and the header's `Wiring` section still said the gate was UNWIRED when lint.yml runs it on every PR with no paths filter — corrected in place, same defect class, no new verification surface.",

ACCEPT — PR #11549. Route (A) taken, and the discriminator was actually checked

Review by the dispatching PM seat (session_015ahemw8RcTgqtxrj15PEZx).

My amendment made the route choice conditional on a fact rather than on my preference: "does this gate have a baseline/ledger file, and is it shrink-only?" It was checked, not assumed — scripts/optional-error-sink-contract.baseline.json exists, a baselined entry that is no longer red fails the gate, and there is deliberately no --fix/--update flag. So the ledger is the durable record, triage's route was the right one, and the third-bucket fallback was correctly not used.

⭐ The widening found a sink the card never named

The card listed two red plugin-sharing sinks, found by hand. The structural population found three — logger@SharingRuleServiceOptions at sharing-rule-service.ts:76, also publicly exported. Verified against the ledger on both sides:

origin/main baseline : logger@ApprovalServiceOptions, logger@SecurityPlugin                    (2)
branch baseline      : + logger@SharingServiceOptions, logger@ShareLinkServiceOptions,
                         logger@SharingRuleServiceOptions                                       (5)

That third row is the argument for this card's whole shape: a hand-listed set of shapes is exactly what a structural population exists to replace, and the hand list was already incomplete when the card was written.

⛔ Both prohibitions held, verified by diff rather than by report

$ git diff --name-only origin/main...<branch>
  scripts/check-optional-error-sink-contract.mjs
  scripts/optional-error-sink-contract.baseline.json

No file under packages/plugins/plugin-sharing is touched. All three newly visible reds are baselined, never flipped, and the gate's exit code on a clean tree stays 0. SharingServiceOptions / ShareLinkServiceOptions / SharingRuleServiceOptions are untouched — that contract call remains #10556's.

⭐ The finding worth more than either blind spot

Ablation B — revert the prefilter — initially left the self-test green. Every prefilter pin tested the constant; none tested the scan. So a pin was added on the call site. That pin also stayed green under the same ablation, because Function.prototype.toString() returns comments verbatim and the comment above the call site names CHANNEL_PREFILTER in prose.

A pin satisfied by a SENTENCE DESCRIBING the code is satisfied by deleting the code and keeping the sentence.

Fixed by stripping comments before matching, and I read the implementation rather than the claim (:1037):

const runBody = run
    .toString()
    .replace(/\/\*[\s\S]*?\*\//g, ' ')
    .replace(/(^|[^:])\/\/[^\n]*/g, '$1 ');
if (!runBody.includes('CHANNEL_PREFILTER.test(')) {

(The [^:] guard so it does not eat https:// is the kind of detail that decides whether a fix like this survives.) Only after that did leg B go red. This is the card's own defect — a claim nothing re-measures — reproduced one level up inside the fix for it, caught by the dev rather than by me.

Also honest and worth keeping: leg C's first run was reported as invalid, not passing — a // marker had commented out a closing }; so the leg measured a syntax error. Re-run with a block comment. An ablation that fails to compile is not an ablation.

The numbers, re-measured because the card's had drifted

	population	red	`noErrorMember`	`unreadable`	exit
base `cd932772`	38	2	57	—	0
prefilter only	38	2	95	0	0
`Function` limb only	41	5	58	3	1
both (this PR)	41	5	96	3	0

Additive: 57 + 38 + 1 = 96. The card's 08-22 figures (37, 54) had already drifted to 38/57 before work started — exactly why I asked for re-measurement rather than inheritance. The tally was undercounting by 40%.

And the equivalence was measured, not argued: removing the prefilter entirely and parsing all 1914 files yields a byte-identical 146-line census. The dev also corrected its own "~5/6 from memory" to a measured 69.9%.

Open question — ruled: B, with a lane boundary

Cross-posting is my call, as the dev correctly said. Ruling B: post a factual pointer, take no contract decision.

I re-checked the referenced card rather than accepting the report's summary of it: #10692 is genuinely pm:blocked, and its body already names record-orphan-cleanup.ts's { info?: Function, warn?: Function } as "a further wrinkle: bare Function accepts any callable". So it is blocked on precisely the producers these new rows name, and has no way to learn the population grew.

⚠️ But #10692 is domain:services, not this lane. So the pointer is information only: ⛔ no grading, ⛔ no label change, ⛔ no dispatch, ⛔ no re-scoping. C is refused — #10556 already exists for this exact debt and a fresh card would duplicate it.

Landing: not a governed surface — ordinary path, ready → arm → poll the queue ref, once every check is green (29 checks, 0 failures, 4 still running at review time).

⛔ The prohibition, checked against the right commit

My watcher's convenience check was pointed at git log -1 — the head at detection time — and #11554 landed in the same window, so that read was about #11554's commit, not this one. Re-done against #11549's own landing commit:

$ git show --name-only 3132c239
  scripts/check-optional-error-sink-contract.mjs
  scripts/optional-error-sink-contract.baseline.json
  plugin-sharing files: 0

SharingServiceOptions / ShareLinkServiceOptions / SharingRuleServiceOptions are recorded, not repaired. The contract call stays #10556's.

Recording the instrument slip because it is the same family as three others this round: "the predicate fired" and "this is the commit that made it fire" are two different claims, and a watcher that prints the current head next to a satisfied predicate invites reading them as one. That is #11363's lesson — two facts side by side get read as a causal statement, and neither has to be false.

What this card bought

The blind spot was not that the gate judged wrong; it was that the gate could not see. error?: Function set fn = false, which hid the member from the population and marked the shape impure, so such a sink landed in no bucket at all — not population, not impure, not noErrorMember. Three red sinks were invisible; the card, working by hand, found two.

The noErrorMember tally was undercounting by 40% (57 → 96 on an unchanged tree), and the equivalence was measured rather than argued: removing the prefilter entirely and parsing all 1914 files yields a byte-identical 146-line census.

Population notices posted to #10556 (its ledger goes 2 → 5, and the three new rows are a third class — publicly exported, so tightening warn is a published-contract break rather than a ? deletion) and #10692 (pm:blocked on exactly these producers). Both information only — no grading, no dispatch; those are domain:services.

#11551 filed for the lint.yml step comment whose three counts are now all wrong.
