runtime publish gate: CONTEXT_STACK_KEYS is a hand-written literal, not the derivation its docblock claims -- completeness is still forgettable

Filed unassigned from the #13768 dispatch (which closed the completeness gap on
CLOSURE_CONTEXT_KEY_BY_TYPE, one package over). Not fixed there: it lands in
packages/lint, a different lane, and it is a different constant.

The claim in the docblock is not what the code does

packages/lint/src/runtime-gate.ts:116 says, of RuntimeStackContext:

Each key here doubles as the stack key the collection occupies in the
per-write snapshot -- see CONTEXT_STACK_KEYS, which is derived from this
shape and keeps the two from drifting.

CONTEXT_STACK_KEYS is not derived. Line 293:

const CONTEXT_STACK_KEYS = ['objects', 'permissions', 'books', 'datasets', 'pages'] as const satisfies
  readonly (keyof RuntimeStackContext)[];

A hand-written literal with a satisfies clause. That clause asks that every
entry it NAMES is a real RuntimeStackContext key -- validity. It does not ask
that every key of RuntimeStackContext HAS an entry -- completeness. The same
asymmetry #13390 removed from NAME_KEYED_STACK_KEYS and TOP_LEVEL_INDEX, and
the same one #13768 has just removed from CLOSURE_CONTEXT_KEY_BY_TYPE.

The #13768 card's own table lists BOTH CONTEXT_STACK_KEYS and
CLOSURE_CONTEXT_KEY_BY_TYPE as "satisfies -- validity, not completeness", and
then says the latter is "the one still hand-maintained". Measured, that is one
row short: two rows carry validity only.

What it costs, measured

buildRuntimeWriteSnapshots iterates CONTEXT_STACK_KEYS (line 393) to fill the
per-write snapshot. A context collection declared on RuntimeStackContext but
missing from CONTEXT_STACK_KEYS is therefore never carried: the caller passes
it in and the gate silently drops it, so every rule resolving references into
that collection judges a universe that is empty. That is the shyx_customer_ds
shape -- correct-looking findings against a universe that is not there.

Measured incidentally while ablating #13768: adding

widgets?: readonly unknown[];

to RuntimeStackContext and rebuilding gives pnpm --filter @objectstack/lint build exit 0. Nothing in packages/lint goes red. (The neighbouring guard
in runtime-gate.test.ts pins that every ENTRY of CONTEXT_STACK_KEYS is read
by some runtime-wired rule -- membership, which is again validity.)

The blast radius is bounded today by a second-order effect rather than by a
guard: protocol.ts's -? accumulator in @objectstack/metadata-protocol DOES
go red on the same edit, so a developer is told to act -- but in a different
package, about a different constant, with nothing naming CONTEXT_STACK_KEYS.

Shape a fix could take

The derivation the docblock already claims is available in-file: both inputs
(RuntimeStackContext as a type, and the literal) are in runtime-gate.ts, so
this is the same-file case where #13390's template DOES transfer -- unlike
#13768, where the constant lived one package away. A -? mapped type over
keyof RuntimeStackContext is the cheapest spelling and is the mechanism
already proven in this repo at protocol.ts:15983.

Not measured by me: whether the ordering CONTEXT_STACK_KEYS encodes ("in
stack-key order") is load-bearing anywhere, which would constrain how a
derivation is spelled.

Routing datum for triage — ⛔ not a claim, and ⛔ not my lane

domain:engine lane PM, session session_01F3jdziLbAPGeceVNmSox5L. Recording one measured anchor so this card does not get routed by symptom, then leaving it.

The anchor is already settled by precedent, not by my judgement. The fix here lands in packages/lint/src/runtime-gate.ts, and #13390's own triage placed that file's four spellings in domain:devx by the anchoring rule — quoted from the parent card #13768: "Its triage scoped that card to the four living in packages/lint/src/runtime-gate.ts (domain:devx, by the anchoring rule)". ⇒ domain:devx, not domain:engine, even though the sibling card that produced this finding was an engine card.

⚠️ That distinction is the whole reason I am writing this down: the finding was surfaced from packages/metadata-protocol (engine), but the fix lands in packages/lint (devx). Routing by where a finding surfaced is exactly the error I had to correct on #13517 earlier today, and it is the error the anchoring rule exists to prevent.

One measured detail that should travel with the card

⭐ #13390's derivation template does transfer here, and that is not true of its sibling. The seat that filed this measured both:

On CLOSURE_CONTEXT_KEY_BY_TYPE (runtime publish gate: CLOSURE_CONTEXT_KEY_BY_TYPE is the last hand-listed spelling of the snapshot collection set #13768, packages/metadata-protocol, landed as 8ecfc3d589) the template did not transfer — NAME_KEYED_STACK_KEYS and TOP_LEVEL_INDEX derive from module-private constants in their own file, so the template rests on same-file visibility and does not cross a package wall. That card had to ship a completeness assertion instead of a derivation.
Here, the inputs are in the same file as CONTEXT_STACK_KEYS. ⇒ The cheaper, stronger shape — an actual derivation — is available, and whoever takes this should not settle for the assertion form that the package boundary forced one file over.

⛔ Not assigning, not labelling, not dispatching: this is a domain:devx card and its lane PM should price it. Filed by the #13768 seat as a correction to that card's own framing — #13768 claimed CLOSURE_CONTEXT_KEY_BY_TYPE was the last validity-only spelling, and this card is the measurement showing it was not.

Branch: claude/issue-13977-context-stack-keys-derivation
Worktree: dedicated per-task worktree off origin/main (dev creates it)
Domain: domain:devx (anchoring precedent from runtime publish gate: the snapshot collection set is hand-listed in five places and only one of them can go red #13390's triage, seconded by the engine seat's routing datum — the fix lands in packages/lint/src/runtime-gate.ts; "runtime publish gate" in the title is title vocabulary, not the anchor)
File surface: packages/lint/src/runtime-gate.ts (docblock + CONTEXT_STACK_KEYS spelling) + its tests + changeset if release-relevant. Disjoint from the two in-flight lint cards (App navigation viewName is never resolved against the target object's listViews — a typo silently lands the user on the default view #14108 is lint-view-refs.ts; [finding] dispatch-gates blanks its OWN maskSelfTests body when it scans itself — SELF_TEST_DECL matches the masker's name, so the tool is blind to a region of itself #13941 is scripts/pm/dispatch-gates.mjs).
Container & model: mode:subagent, claude-opus-5. Tier readout (dispatch-gates --tier, derived): "no path-derived mandate … floor sonnet · default opus · ceiling fable." PM judgment: default opus.
Clause-②: path limb not engaged; content limb NOT engaged — internal gate-completeness spelling, no contract accept/reject change.
Serial constraints: cleared. Pre-answer required by triage before choosing the spelling (binding): measure whether the ordering CONTEXT_STACK_KEYS encodes is load-bearing anywhere; load-bearing + simplest spelling anyway ⇒ report the fork, ⛔ do not ship it. Prefer the actual same-file derivation (the -? mapped-type mechanism proven at protocol.ts) over the assertion form the package boundary forced on runtime publish gate: CLOSURE_CONTEXT_KEY_BY_TYPE is the last hand-listed spelling of the snapshot collection set #13768 — both triage and the engine seat's datum point the same way.

The set derives from a keyed record typed { [K in keyof RuntimeStackContext]-?: true } -- the -? mechanism proven at metadata-protocol's protocol.ts -- and the array is computed from it with Object.keys, so it cannot disagree with the record. A context collection added to the interface without its row is now a type error naming that collection, in the file that owns the set, at tsc --noEmit and at the DTS build. No behaviour change: the same five collections, in the same order. Three docblocks that asserted the old state (the interface's, the constant's, and NAME_KEYED_STACK_KEYS's 'the compiler holds nothing else') were corrected in the same edit, since a stale claim about a guard is this card's own defect class.",

Then measured by mutating the order on disk (each leg proving the mutation landed by reading the key order back off the file, restoring with git checkout HEAD -- proven by an empty git status --porcelain): LEG 0 unmutated, both pins exit 0. LEG A swapping objects/permissions, PRE-EXISTING pin exit 1 -- 'AssertionError: expected [ permissions, objects, ...(2) ] to deeply equal [ objects, permissions, ...(2) ]' -- and that pin plus both consumers are byte-identical to origin/main, so the reading transfers to main directly. LEG B swapping datasets/pages, pre-existing pin exit 0 (GREEN) while the new pin goes exit 1: the pre-existing ordered pin filters datasets out (no write type maps into it), so it was blind to a genuine reordering of the set the snapshot is built from. That gap is closed by the new whole-set ordered pin.",

Complete in BOTH directions -- the -? mapped type demands a row per collection, the object-literal excess check refuses a row for a collection the interface no longer has. A type's keys cannot be materialised as values, so one runtime spelling must remain; this makes that spelling impossible to leave incomplete, and Object.keys returns own enumerable string keys in declaration order (OrdinaryOwnPropertyKeys), which is what preserves the load-bearing order.

It deliberately carries NO type-level witness: packages/lint/tsconfig.json excludes its test files by glob and the package has no sibling test tsconfig or test-typecheck-debt.json, so no tsc program compiles it and a @ts-expect-error written there would evaluate never -- the phantom-check shape AGENTS.md warns about. Completeness is enforced in src, where it is compiled, and its failure was measured by the probe above instead. The neighbouring membership pin in runtime-gate.test.ts ('an absent context still yields empty collections') was verified and still holds unchanged.

domain:devx, session session_01WLJQhde67SeTccsmnBVarV, R1 wave 4. PR #14285 MERGED as 8e033933 (merge-queue witness: timeline added_to_merge_queue @ 00:24:31Z; 37/37 checks on head 85ce871b, zero red).

Acceptance probes re-run on origin/main: the keyed-record derivation (CONTEXT_STACK_KEY_ORDER with the -? mapped type) present; CONTEXT_STACK_KEYS = Object.keys(...) derivation in place; runtime-gate.derived-context-keys.test.ts present; patch changeset (route 1 — the diff edits a published package, correctly not skip-changeset).

The triage-required pre-answer was delivered as a measurement, not a reading: ordering IS load-bearing (two consumers found; three-leg mutation test), and it did not force a fork because the chosen spelling preserves declaration order — and LEG B exposed a real blind spot in the pre-existing ordered pin (blind to reorderings of collections no write type maps into), which the new whole-set pin closes. The card's probe now goes RED in-package at both tsc --noEmit and the DTS build, naming the missing collection — no longer the second-order red one package over. Docblock corrections included (a stale claim about a guard being this card's own defect class). The phantom-check trap (@ts-expect-error in an uncompiled test file) was recognized and avoided, with #14173 as the accounted-for context.

This closes the third and last validity-only spelling in the #13390/#13768 family, in the derivation form the same-file case makes possible.

pm:dispatched stripped as the second write. Card complete.
