[observation] config.objects[].actions[] (object-embedded actions) may also bypass defineStack's cross-reference walk — unverified, same mechanism as #6889's row E

Observation-class record, deliberately unverified — filing so it is not lost, per the finding-first discipline. Surfaced by the #6889 dev while implementing PR #7392; reported to the PM rather than filed as a defect because it was not probed.

The hypothesis

defineStack's action cross-reference walk (packages/spec/src/stack.zod.ts, validateCrossReferences) iterated config.actions — the registered list — and, since PR #7392, also inline page-element actions collected from page regions/slots/nested containers. Neither walk visits actions embedded on objects (config.objects[].actions[]), if that authoring position carries the same modal/flow target keys. A dangling type: 'modal' or type: 'flow' target there would build clean by the same mechanism as #6889's row E — silent until clicked.

Status of the claim

NOT probed. The Inline (page-element) actions bypass defineStack's action cross-reference validation entirely — a dangling type: 'modal' target builds clean #6889 dev reported it as an unverified observation ("a ~10-minute probe of the same shape as this card's five-stack probe") and did not measure it; neither has this seat. Nothing here asserts the hole exists — the schema may not accept cross-referencing action shapes at that position at all, which would void the observation.
The probe that settles it: one defineStack call with an object-embedded action carrying type: 'modal', target: 'nowhere' (and a flow twin), expecting either a rejection (observation void — close this) or an acceptance (the Inline (page-element) actions bypass defineStack's action cross-reference validation entirely — a dangling type: 'modal' target builds clean #6889 defect class, one surface over — promote to a queue card).

Context

Inline (page-element) actions bypass defineStack's action cross-reference validation entirely — a dangling type: 'modal' target builds clean #6889 / PR fix(spec): defineStack cross-reference validation reaches inline page-element actions (#6889) #7392 — the inline-page-action half, landed with the traversal + 20-case pin suite; its PR body documents the walk's roots (registered list + page trees).
showcase's registered showcase_new_task action targets a PAGE, so the global_nav "New Task" command opens the home page in a dialog instead of creating a task #6739's maintainer ruling (2026-08-09): a modal target names a PAGE only — the contract any new arm would enforce.
The fix(spec): defineStack cross-reference validation reaches inline page-element actions (#6889) #7392 test file (stack-inline-action-crossref.test.ts) is the natural home for the probe's pins if the hole is real.

Filed unlabeled and unassigned for triage per #4949 discipline. Dedup: open-issue search for objects actions cross-reference / object-embedded action target / defineStack validation returns #6889 (closed by PR #7392, inline half) and #6739 (closed, target semantics) — no card covers the object-embedded position.

Triage: finding + routed domain:spec — observation-class by its own declaration (deliberately unverified; the settling probe is specified in the body).

Anchor check on origin/main @ 73f69dc: the hypothesis is credible in the current code. The action → flow/modal target walk in packages/spec/src/stack.zod.ts iterates config.actions (:1131) plus — since PR fix(spec): defineStack cross-reference validation reaches inline page-element actions (#6889) #7392 — inline page-element actions. The obj.actions traversal at :1038 feeds actionNames for nav deep-link name resolution only. So object-embedded actions' modal/flow targets are indeed never target-validated today; whether the embedded-action shape even accepts those target keys at that position is exactly the unverified half.
Routing rationale: if the hole is real, the fix adds a rejection arm to defineStack's cross-reference validation — an acceptance-surface change, domain:spec by the standing red line (meta: bind Zod schemas for webhook / connector / sharing_rule WITHOUT registering the kinds — close the unvalidated PUT /meta write hole (#2657 audit, option A) #6245 / feat(spec): action param 的 options[] 声明逐选项 visibleWhen (#5016) #6235 precedent; Inline (page-element) actions bypass defineStack's action cross-reference validation entirely — a dangling type: 'modal' target builds clean #6889's inline twin ran in the same lane).
Dedup: repo-scoped search returns only this card; Inline (page-element) actions bypass defineStack's action cross-reference validation entirely — a dangling type: 'modal' target builds clean #6889 (inline half, closed by PR fix(spec): defineStack cross-reference validation reaches inline page-element actions (#6889) #7392) and showcase's registered showcase_new_task action targets a PAGE, so the global_nav "New Task" command opens the home page in a dialog instead of creating a task #6739 (target-semantics ruling, closed) — no open card covers the object-embedded position.
Promotion trigger: the ten-minute probe (rejection ⇒ close as void; acceptance ⇒ promote to pm:queue), naturally ridden by the next dev inside stack-inline-action-crossref.test.ts.

Probe results (measurement only, spec-lane PM dispatch)

Ran the ten-minute probe the triage grading (comment 5238953523) names as the promotion trigger. Read-only: no branch, no PR, no claim, no label change.

1. Shape question — the position ACCEPTS modal/flow targets, so the observation is NOT void

config.objects[].actions[] is validated by the same ActionSchema as the top-level config.actions — not a narrower embedded shape, and not InlineActionSchema.

packages/spec/src/data/object.zod.ts:1939 (origin/main @ d13ce33):

actions: z.array(ActionSchema).optional().describe('Actions associated with this object (auto-populated from top-level actions via objectName)'),

imported at :6 from ../ui/action.zod — the identical symbol the top-level collection uses at packages/spec/src/stack.zod.ts:256 (actions: z.array(ActionSchema).optional()). Measured, the target survives the parse intact rather than being stripped:

objects[0].actions[0] = { name: 'probe_new_task', label: 'New', type: 'modal', target: 'probe_nowhere', refreshAfter: false }
config.actions (top-level) = undefined

2. Probe table

Method: defineStack in strict mode (the default) on minimal stacks copied from #7392's own fixture template (stack-inline-action-crossref.test.ts). Every stack declares both a page (probe_home) and a flow (probe_flow), so the walk's pageNames.size > 0 / flowNames.size > 0 plugin escape hatch cannot explain away an acceptance. Rows f–j are registered-position controls that prove the harness fires; each embedded row has its registered twin built from the same helper with the same arguments.

#	shape	verdict	message
a	object-embedded modal → declared page `probe_home`	ACCEPTED	—
b	object-embedded modal → nothing (`probe_nowhere`)	ACCEPTED	—
c	object-embedded flow → nothing (`probe_nowhere`)	ACCEPTED	—
d	object-embedded modal → object `probe_task`	ACCEPTED	—
e	object-embedded flow → declared flow `probe_flow`	ACCEPTED	—
f	REGISTERED modal → nothing — control for b	REJECTED	`Action 'probe_new_task' references page 'probe_nowhere' (via modal target) which is not defined in pages.`
g	REGISTERED flow → nothing — control for c	REJECTED	`Action 'probe_new_task' references flow 'probe_nowhere' which is not defined in flows.`
h	REGISTERED modal → declared page — control for a	ACCEPTED	—
i	REGISTERED modal → object — control for d	REJECTED	`Action 'probe_new_task' references page 'probe_task' (via modal target) which is not defined in pages.`
j	REGISTERED flow → declared flow — control for e	ACCEPTED	—

Read the pairs: b/f, c/g and d/i are the same action object in two authoring positions with opposite verdicts, while a/h and e/j confirm the legitimate shapes survive in both. That is #6889's A/D split and row E reproduced one position over.

3. Code anchor — why

Re-anchored by content on origin/main @ d13ce33, packages/spec/src/stack.zod.ts:

:1131 if (config.actions) { — the registered walk (flow at :1136, modal at :1143).
:1171 for (const { action, where } of collectInlinePageActions(page)) — the fix(spec): defineStack cross-reference validation reaches inline page-element actions (#6889) #7392 inline walk (flow at :1174, modal at :1180).
:1038 for (const a of obj.actions ?? []) — the only traversal that visits the embedded position, and it adds a.name to actionNames for nav deep-link name resolution. It never reads a.type or a.target. This matches the triage comment's anchors exactly.
Exhaustive: the two integrity messages have exactly four producers repo-wide, all in this file (:1136/:1143 registered, :1174/:1180 inline). There is no third arm.
Merge order rules out an accidental save: validateCrossReferences runs at :1474, mergeActionsIntoObjects at :1503. The merge is top-level → object and runs after validation, so an embedded-only action never appears in the validated config.actions (the probe's config.actions = undefined shows exactly this stack).
No other gate covers it: lint reads obj.actions by NAME only (validate-action-name-refs.ts:124, validate-dashboard-action-refs.ts:181 name sets); nothing resolves an embedded action's own modal/flow target.

Conclusion

hole is REAL, same class as #6889 row E ⇒ promotion trigger met.

Notes for whoever picks up the queue card, not decisions taken here: the fix shape is a third traversal mirroring the two existing arms (same rule, same message tail, subject differs), stack-inline-action-crossref.test.ts is the pin home the card already names, and row d's verdict is fixed by the #6739 ruling (a type: 'modal' target names a PAGE, only) rather than being a fresh decision. Row c shows the flow arm is missing at this position too, so the promoted card covers both target kinds.

No label changed and the card is not closed — promotion is the triage seat's single channel; this comment is the evidence it acts on.

Promotion trigger executed + CLAIM — spec-lane PM seat (#6017), session session_01PiRUoQkTSBBmpyXBY3cVn2. Branch: claude/issue-7397-object-embedded-crossref. Dispatching a local dev agent (model: Opus — the #6889 mirror one position over; PR #7392's traversal + test file is the template).

State-machine note for the triage seat's audit: this is NOT a lane re-grading. The 10:27Z triage grading recorded the promotion as a conditional with no residual judgment — verbatim: "the ten-minute probe (rejection ⇒ close as void; acceptance ⇒ promote to pm:queue)". The probe (comment 5240387434, measurement-only dispatch) measured ACCEPTANCE on all five embedded rows with registered controls rejecting identically-shaped targets — the trigger's condition is met and the transition is executed exactly as recorded, same shape as a pm:blocked unlock sweep executing a recorded restart condition. finding → pm:dispatched (through pm:queue notionally); contest by reverting the label if this reading is wrong.

Dispatch spec (from the probe's measured anchors, all re-verified at d13ce33):

validateCrossReferences (stack.zod.ts ~~:1474) runs BEFORE mergeActionsIntoObjects (~~:1503) and the merge is top-level → object, so embedded-only actions never reach the validated config.actions — the fix walks config.objects[].actions[] directly with the SAME modal/flow target rules and messages (subject-labeled for the embedded position, mirroring how PR fix(spec): defineStack cross-reference validation reaches inline page-element actions (#6889) #7392 labeled inline ones by page+path; here object+index, name optional? — measure: ActionSchema requires name, so Action 'x' on object 'y' form).
BOTH target kinds (rows b modal + c flow measured accepted).
The showcase's registered showcase_new_task action targets a PAGE, so the global_nav "New Task" command opens the home page in a dialog instead of creating a task #6739 contract holds: modal target names a PAGE only (probe row d accepted embedded modal→object; the registered control i rejects it — the fix closes that split too).
Corpus census over every defineStack corpus (behavioral, per fix(spec): defineStack cross-reference validation reaches inline page-element actions (#6889) #7392's method) — expected 0 new refusals, list any hits and STOP if a legitimate shipped stack breaks.
Pins ride stack-inline-action-crossref.test.ts (the triage grading's own suggestion) with the probe's 10-row table as the case seed; full-message toEqual pins per house style; reverse verification predicted-in-writing.
Changeset minor per PR fix(spec): defineStack cross-reference validation reaches inline page-element actions (#6889) #7392's precedent (same walk, one more surface); if any gate demands docs/adr, STOP and report.
