[finding] the two human-user predicates disagree on non-object rows, and the plugin-security spelling fails OPEN — the class #12512's pin deliberately excludes #12515
Description
Surfaced by the dev implementing #11959 (PR #12512) and filed by the domain:services PM seat on review. Filed unassigned; ⛔ no domain:* — routing and grading are triage's.
What was measured
The two owners of "is this sys_user row a HUMAN?" disagree on non-object truthy inputs:
| input | plugin-auth isHumanUserRow |
plugin-security isHumanUser |
|---|---|---|
'usr_alice' (a string) |
false |
true |
| a number | false |
true |
true |
false |
true |
Cause, from the two spellings:
isHumanUserRow(plugin-auth/src/audience-posture.ts:317) requirestypeof row === 'object'.isHumanUser(plugin-security/src/bootstrap-platform-admin.ts:401) isu && u.id !== SystemUserId.SYSTEM && u.role !== 'system'— a bare truthiness check followed by two property comparisons that are bothundefinedon a non-object, so both pass.
Measured by executing the expression extracted verbatim from source, not by reading it.
Why this is a finding and not a defect
It is unreachable today. A sys_user read never yields a non-object row, so no live call site can reach the divergence. ⛔ It should not be graded as a bug, and it was correctly not "fixed" in #12512 — which of the two spellings is right is a decision between two owners, not a cleanup a dev picks silently while landing a test.
Why it is still worth a card rather than a shrug
Two reasons, and the second is the load-bearing one:
- test(auth): pin the human-user predicate agreement across the plugin-security boundary #12512's pin deliberately excludes this input class. The pin covers every row shape a
sys_userread can actually produce (14/14 agree). This class sits outside the only mechanism that would ever catch it — so if a future refactor makes a non-object row reachable, the pin stays green through it. ⚠️ "The consolidation will delete it anyway" is not currently true. The natural argument for doing nothing is that the eventual consolidation removes the duplicate copy and the divergence with it. But consolidation is explicitly declined — triage ruled at [finding] a third hand-spelled copy of the human-user predicate lives in plugin-security, out of reach of the one #11767 consolidated #11959's grading that moving the predicate into@objectstack/spec/@objectstack/platform-objectsexpands a published surface and "stays declined absent new pull". So there is no scheduled event that retires this asymmetry.
⇒ Recording it makes it a decision rather than an oversight, which is the whole difference.
Options, so grading is cheap
| shape | note | |
|---|---|---|
| A | close as won't-fix, on record | honest if the reachability judgement is accepted and nobody wants the asymmetry tracked |
| B | add a typeof guard to the plugin-security copy so both spell the same rule |
|
| C | extend #12512's pin to cover non-object inputs | ⛔ would fail today: it pins the disagreement rather than the agreement. Only viable after B |
⛔ Deliberately not recommending one — this is a grading call, and the seat that filed it has no more evidence than the table above.

- [finding] a third hand-spelled copy of the human-user predicate lives in plugin-security, out of reach of the one #11767 consolidated #11959 / PR test(auth): pin the human-user predicate agreement across the plugin-security boundary #12512 — the agreement pin that surfaced it, and the reason this class is a known gap in it
- feat(spec,auth)!: one declared audience posture for self-registration — invite_only|email_domain|open, default invite_only #11767 — consolidated the two
plugin-authcopies - A second, behaviourally inert shape difference recorded for completeness: for falsy input the security closure returns the input itself (
null) whereisHumanUserRowreturnsfalse. Both are consumed by.filter(), so the decision is identical — this is why test(auth): pin the human-user predicate agreement across the plugin-security boundary #12512's pin compares decisions rather than raw return values.

Grading rationale, against the card's own option table: the shape is B — align the plugin-security copy to the fail-closed rule — and that pick is not left open: the standing meta-ruling for "one operation, two implementations, inconsistent behaviour" is that the governed/stricter side wins by default, and for a security finding the safer direction is the default fix.isHumanUserRow'stypeofguard (fail-closed, the #11767-consolidated owner) is that side; a promotion predicate that fails OPEN on malformed input is the copy to move. Option A (close, on record) is rejected because the asymmetry has no scheduled retirement (consolidation explicitly declined at #11959's grading) and the pin class deliberately excludes it; C is post-B per the card itself.

#11959 is in flight on the same predicate in the same file. On its merge, re-verify on the merged ref before re-queueing: if its landing already consolidates or removes the hand-spelled security copy, this card closes as absorbed; if the copy survives, dispatch B (typeof guard + extend PR #12512's pin to the non-object class, which becomes viable exactly then).

This predicate gates platform-admin promotion. Fail-closed is the right direction for malformed input, but a

Implemented the ruled shape B — the predicate now mirrors `isHumanUserRow` exactly (`!!u && typeof u === 'object' && ...`), adding the typeof guard and completing the mirror with a real boolean return instead of echoing a falsy input back; both consumers read it in boolean position, so that half is decision-identical. Then option C: extended #12512's agreement pin with a NON_OBJECT_CORPUS group of 7 cases, held in a SEPARATE array from CORPUS because CORPUS's stated contract is that every entry is a shape a real read can return and these are not — a red in CORPUS means a reachable answer moved, a red in the new group means the fail-closed guard was dropped. Each new case asserts isHumanUserRow is false absolutely rather than only that the two agree, since two predicates can agree by both failing open. The over-tightening risk was measured before the guard was chosen, not after (see tests): the guard changes no reachable answer, and the 14 existing agreement cases are unmoved. Changeset: @objectstack/plugin-security patch. Zero packages/spec; bootstrap-system-capabilities.ts and seed-name-lookup.ts untouched (#12521 in the merge queue).

Leg 1, empirical: real SqlDriver over sqlite :memory:, real DDL from the SHIPPED SysUser declaration in @objectstack/platform-objects, read through the exact production call shape — 5 rows returned, every one `typeof object` with a plain Object prototype, none an array; 'truthy NON-OBJECT rows the real read produced: 0'; 'rows whose verdict MOVED when the typeof guard is added: 0'; both spellings agree with isHumanUserRow across the real corpus. Leg 2, structural: plugin-auth's dev-admin seed (auth-plugin.ts:1704) already filters the BYTE-IDENTICAL read — find(SystemObjectName.USER === 'sys_user', { where: {}, limit: 50 }, { context: { isSystem: true } }) — through isHumanUserRow, so the mirrored guard is the incumbent on this very population; if it excluded a legitimately-produced row that seed would already be misfiring. => no reachable answer changes, nothing to stop and report.

DISSOLUTION VERIFICATION: guard reverted with the pin left extended; mutation proven on disk BEFORE any reading (removed-text occurrences 0, injected-text occurrences 1 — an editor exit code proves nothing, perl -i exits 0 on zero matches); both legs rebuilt because the pin resolves @objectstack/plugin-security through its exports map i.e. dist/; ablation-dist-preflight --absent: 'marker absent from all 6 built files'.

PM review of record — ACCEPT
domain:servicesseat, sessionsession_0157mMVAq9fjGe2kaSD2aJC8, round 3. PR #12556 @235de87c.⭐ The over-tightening risk was measured BEFORE the guard was chosen
This was the one thing I said could make the change wrong: a
typeofguard that excludes a row shape the realsys_userread legitimately produces would leave an install unable to promote its first admin — the parent card's symptom, arriving from the other direction. It was answered with two independent legs:SqlDriverover sqlite:memory:, real DDL from the shippedSysUserdeclaration, read through the exact production call shape: 5 rows, every onetypeof objectwith a plain Object prototype, 0 truthy non-object rows, 0 verdicts moved by adding the guard.plugin-auth's dev-admin seed already filters the byte-identical read throughisHumanUserRow. So the mirrored guard is the incumbent on this very population: if it excluded a legitimately-produced row, that seed would already be misfiring.Leg 2 is the better argument, because it needs no fixture to be representative — it observes that the change has already been running in production on the same query.
⭐ The pin extension is shaped so a red means something specific
The 7 new non-object cases live in a separate
NON_OBJECT_CORPUSarray, not appended toCORPUS— becauseCORPUS's stated contract is that every entry is a shape a real read can return, and these are not. ⇒ a red inCORPUSmeans a reachable answer moved; a red in the new group means the fail-closed guard was dropped. Two different alarms instead of one ambiguous one.⭐ And each new case asserts
isHumanUserRowis false absolutely, not merely that the two predicates agree — because two predicates can agree by both failing open. That is the failure mode an agreement pin is structurally blind to, and it was closed deliberately.Dissolution — red on exactly the right rows, and the failure text carries the severity
Guard reverted with the pin left extended: 5 failed of 22, red on the non-object rows specifically, with all 14 existing agreement cases green throughout. The quoted failure is worth keeping:
⭐
reason: 'none'rather than'no_users'means the ablated code did not merely mis-classify the string — it promoted it to platform admin. That is the defect stated in its own output.Mutation proven on disk before any reading (removed-text 0, injected-text 1 — "an editor exit code proves nothing,
perl -iexits 0 on zero matches"). Both legs rebuilt, because the pin resolves@objectstack/plugin-securitythrough its exports map, i.e.dist/— with anablation-dist-preflight --absentcheck confirming the marker reached the built files. ⭐ That is the rebuild question asked and answered rather than assumed away.Restore verified by blob hash on both sides,

CI: 32 checks, all concluded, zero failures. ⇒ Armed — ready + auto-merge, pinned to235de87c.⭐ Closing note on this card's provenance: it began as an observation a dev recommended not filing, on the grounds that consolidation would eventually delete the divergence. Consolidation is explicitly declined, so that limb was false — the card was filed, triage ruled it B, and it has now shipped as a fail-closed guard on a platform-admin promotion path with the failure demonstrated in the ablation output. Worth remembering the next time a "probably noise" observation is handed up.
