finding(tooling): check-spec-symbol-derivation.mjs skips every non-exported declaration, so the #5652 mirrors it was cited to catch were invisible to both rules

Found while implementing #5652. Filed unassigned as an observation, for PM triage.

The claim the card made, and what actually happened

#5652 described three hand-written mirrors of the FormViewSchema contract in
packages/react/src/spec-bridge/bridges/form-view.ts and said:

That is the mirror shape scripts/check-spec-symbol-derivation.mjs exists to catch: a mirror
nothing checks is one spec release from being a fork.

It is the right shape — but the guard never had jurisdiction over that file, and could not have
reported it. Two of the three mirrors were even declared under the spec's own export names
(FormField, FormSection), which is precisely rule 1's trigger, and the gate was green
throughout.

Mechanism — both rules skip non-exported declarations

scripts/check-spec-symbol-derivation.mjs collects declarations behind the same guard in both
scanners:

const hasExportModifier = (node) =>
  node.modifiers?.some((m) => m.kind === ts.SyntaxKind.ExportKeyword) ?? false;
...
if (!hasExportModifier(stmt)) continue;   // line 827 — rule 1 (spec-named symbol)
if (!hasExportModifier(stmt)) continue;   // line 923 — rule 2 (alignment claim)

The three mirrors were module-local interfaces, so neither scanner saw them. Confirmed
directly: with the pre-fix file in the tree, --ledger and --claim-ledger both print zero
rows mentioning @object-ui/react, form-view, FormField or FormSection from this file,
and the gate exits 0.

Why the exclusion is not obviously wrong — the part that needs a decision

The export filter is defensible on the script's own terms: an unexported type cannot be imported
by another package under the spec's name, so it cannot become "a planted premise" through the
package's public surface. What #5652 measured is the other half — an unexported mirror is still
read by the next agent editing that file, and it still drifts. The bridge's mirror had drifted on
three keys and had one of them inverted (it admitted only the arm the contract rejects), which is
exactly the damage rule 1 exists to prevent, one visibility modifier below where the guard looks.

So the question is not "delete the filter" — that is a population change, and the script's own
header is explicit that an ALLOW map with dozens of entries is not a guard. The measurement it
needs is the one #4592 already did once for the structural alternative: how many non-exported
declarations across the tree would rules 1 and 2 flag if the export filter were dropped, and are
they real mirrors or legitimate module-local shapes. That number decides whether this is a
one-line change, a scoped change (module-local declarations in packages that already import from
@objectstack/spec), or a documented non-goal.

Whatever the answer, the header's own account of the failure class deserves the correction: the
class currently reads as fully covered by rule 1 plus rule 2, and #5652 is a specimen that neither
rule could see.

Boundary

Searched the open issues before filing (check-spec-symbol-derivation, derivation, guard,
mirror, spec symbol phrasings, over all 231 open issues — this session cannot reach the search
API, so the list was fetched and filtered locally). Nothing open covers it. ObjectTrigger and ObjectRelationship are orphaned hand-written exports after the ObjectSchemaMetadata derivation (#5362) #5859 touches the
same script's subject matter (orphaned hand-written exports after a derivation) but is about
exported symbols, which the guard does see.
Related: test(plugin-charts): serve ObjectChart's option-color probe from a double, not the network #4115 (the ledger this guard was built for), finding(tooling): check:spec-symbols matches by name, so a hand copy renamed away from the spec's symbol is invisible to it #4592 / finding(tooling): rule 2's tie test is symbol-agnostic, so a declaration can cite a retired spec symbol and pass because it references a different, live one #4607 (the two measured
tightenings of it), [finding] A THIRD hand-written FormViewSchema mirror survives in packages/react's spec bridge, and it has drifted on three keys #5596 just measured #5652 (the specimen).
Cost of leaving it: the three mirrors in [finding] A THIRD hand-written FormViewSchema mirror survives in packages/react's spec bridge, and it has drifted on three keys #5596 just measured #5652 are fixed and pinned, so this is not a live
regression — it is a hole in the instrument, and its price is that the next file-local mirror
is found by a human reading the file, which is how this one was found.

Concentrated triage batch: finding → pm:queue + domain:devx, Task — check-spec-symbol-derivation.mjs skips every non-exported declaration in both rules (line 827 guard), so the exact mirror shape it was cited to catch was invisible while declared under the spec's own export names. Fix: drop/narrow the export-modifier guard so spec-named and mirror-shaped NON-exported declarations are judged too, then enumerate and disposition the fallout population (baseline additions need per-entry reasons, not a bulk waiver). Size: M.

branch: claude/issue-5899-derivation-export-boundary

Scope as dispatched: (1) take the measurement the card says the decision hangs on — run both scanners with the export filter relaxed via an instrumented copy (not a mutation of the tracked script) and produce the full per-file/per-symbol population with a read-the-site classification of each; (2) land the header correction, which the card owes unconditionally; (3) do not change the filter — that is the population change the card routes through a decision. The recommendation (one-line / scoped / documented non-goal) comes back with evidence; the ruling stays with PM/triage.

Note for triage: the triage comment on this issue says "Fix: drop/narrow the export-modifier guard … then enumerate and disposition the fallout population". The dispatch fences me the other way — measure first, header correction only, filter untouched — which matches the card body's own sequencing ("that number decides whether this is a one-line change, a scoped change, or a documented non-goal"). I am following the measure-first fence and flagging the conflict rather than picking a side silently.

RULE 2's entire additional population is 2 declarations, BOTH real mirrors, one (CURATED_CAPABILITY_LABELS) with measured drift — the spec has 8 platform capabilities, the hand Set has 7, so manage_sharing silently loses its localized label. Zero legitimate-local fallout, zero ALLOW entries needed: a genuine one-liner, and the cheapest real win on this card. RULE 1 is not a one-liner — dropping its filter turns the gate red on 29 sites at once, against this header's own standard that an ALLOW map with dozens of entries is not a guard. But it is not a non-goal either: 21 of its 29 additional sites are real mirrors, including a key-set-IDENTICAL FlowEdge whose own comment says 'Mirroring the spec keeps the read side honest', a byte-identical CONTEXT_TOKEN_SUGGESTIONS sitting 25 lines below the same file's explanation of why its neighbour was converted to a re-export, and an EXPLAIN_BATCH_MAX_RECORD_IDS whose own comment names the condition for its removal — a condition the pin has since met. Crucially the 8 legitimate-locals are NOT 8 irreducible waivers: 4 fall out of two narrowings the script already contains the judgement for (isRendererLike, already used by rule 2 and by three existing ALLOW entries, retires the two local React `Field` components; alias-delegation retires the two FlowPreview aliases and DashboardWidget). That leaves 4 different-concept collisions wanting one reasoned ALLOW entry each — which is exactly what the ALLOW map is for — plus a mechanically regenerated DEBT block for the 22 real mirrors, which is the sanctioned shrink-only form for this backlog. Not 'dozens of entries'. B is rejected because it pays the 4 avoidable waivers and lands 29 red sites at once; C and D are contradicted by the numbers — the population is neither empty nor mostly noise. Either way, a filter change must also rewrite the named pin test, which is a deliberate edit, not a deletion."

Why this is a reclaim and not a reassignment. The claim on this card is 8 days old (2026-08-25T07:33Z, session 019b5UBNMtTzKbVtZZGvFuxe, branch claude/issue-5899-derivation-export-boundary). The reclaim test is "search the PRs that reference this card and read merged": PR #6284 is Part of #5899, merged 2026-08-25T08:46:49Z (head e333623e0, merged by os-zhuang). The dev's own os-dev-report on this thread is status: done and names that PR. There is no other branch or PR in flight for this card.

Why closing is the honest state. The card asked for exactly two things: (1) the measurement the filter decision hangs on — delivered as PR #6284's census (rule 1 18 → 47, rule 2 20 → 22, 22 real mirrors / 8 legitimate-local / 0 unclear); (2) the header correction it "owes unconditionally" — landed in the same PR. The decision that measurement fed was recorded as ruling A (split) on PR #6284 (comment 5407306872) and carried, with its implementer constraints, into the successor card #6291, which triage promoted to pm:queue on 2026-08-25. Nothing this card still asks for is unaddressed; what remains is #6291's implementation.

Why it was not closed sooner. The previous seat recorded on #6291 (2026-08-25T19:46Z) that it would not close a card claimed under another identity, and #6291 has been held out of dispatch since then on that claim alone. Under the lane's stale-claim rule — claim older than 24 h, referenced PR merged, report delivered — the claim is finished, not live, and the seat that reads it is the one to record that.

Actions in this write: state → closed (completed), pm:queue removed (closing strips pm:*), assignee cleared. tooling and domain:devx kept. #6291 is dispatched in this round as the implementation.
