spec(types)!: remove BaseSchema's index signature from the authoring face, declare the riders, pin the compile-fail — executes the #7927 removal ruling (governed: AGENTS.md #0.1)

[claude]

Priced by the domain:spec @ objectui seat on #7935. ⛔ Filed unassigned, not claiming.

⭐ RE-SCOPED 2026-09-09T00:1xZ by the domain:spec@objectui seat — the previous body's blast radius was 2.8× understated

Ruled at #8327 5587717012, option A («re-scope now, do not let #8347 discover it mid-flight»), on the measurement at #8327 5587605667. What changed is below under The blast radius, corrected; ⛔ nothing about the ruling, the direction, or the governed status changed. Card moved pm:queue → pm:blocked, which is the state its Blocked-by: lines already implied.

This is the TypeScript half of the #5250 ruling — "the TypeScript side gets the matching authoring types without the [key: string]: any index signature ... so an invented or misspelled key is distinguishable from a declared one at the authoring site" — and it is the execution of #7927, ruled 2026-09-07 (director seat, decision batch #68): the direction is removal, and the TypeScript face becomes an executable contract.

⚠️ The AGENTS.md §5 #0.1 amendment rides here, and it makes this PR governed (draft PR + human merge). It belongs with this card, not earlier, because the amendment should describe what shipped rather than what was intended.

What is being removed, and what inherits it

Measured at origin/main fa7d66c45 by #7581's TypeScript-face census, re-confirmed present at 5505aec:

• [key: string]: any is declared at 12 sites in packages/types/src.
• 120 interfaces extends BaseSchema directly and inherit it.
• The two the ruling cites as base.ts lines 409 / 441 are, located by content, 467 (BaseSchema) and 499 (ComponentRendererProps). ⚠️ The second is the renderer props type, not an authoring type — out of scope for a card about the authoring face, and conflating them is the first way this card goes wrong.

⭐ The blast radius, corrected — 112 reads / 88 keys / 23 files, ⛔ not 58 / 21

This card previously carried "58 real code reads across 21 files" from #8327. That figure does not reproduce, and #8327 falsified it against its own instrument, its own population and its own ref (5587605667):

row	at c842594 (the figure's own ref)	this card used to say	at 154fe2a
production files in the population	1596	1596	1598
raw text (comments + string literals in)	92 keys / 27 files	92 keys / 27 files	92 keys / 27 files
stripped	89 keys / 24 files / 113 reads	58 keys / 21 files	88 keys / 23 files / 112 reads

The raw row reproduces exactly, which localises the defect: 58/21 describes #8327's own per-file table, and that table is a strict subset of the read set — plugin-view/src/ObjectView.tsx alone carries 31 cast reads and was absent from it (58 + 31 = 89). ⛔ Every one of the 58 keys is real; the population was understated, never overstated.

The three-way split, which is what actually re-scopes this card

class	reads	what it is	what it owes
(a)	29	genuinely undeclared on the type the renderer is handed, and read	⛔ a ruling each, ⛔ not a declaration
(b)/(a)	8	union schema; the key is declared on exactly ONE arm	a per-arm decision
(b)	38	declared — the cast is stale, or forced by an untyped local	ordinary cleanup, ⛔ not this card
(c)	31	⭐ ALREADY RULED non-author surface, with in-repo pins	⛔ NEVER declare
(c?)	1	the same producer-derived key as a (c) ruling, unpinned at its site	a pin, or a ruling
(d)	5	⛔ NOT ANSWERABLE — the renderer is handed any	a typing fix first

⭐ 31 of the 112 must NEVER be declared — the #5091 grid ruling (pinned by plugin-grid/src/__tests__/gridNonAuthorKeys.test.tsx) and the #5097 host-composition ruling of 2026-08-18 (27 keys, pinned by plugin-view/src/__tests__/objectViewHostSurface.test.tsx). Both docblocks say the cast is deliberate. A sweep that read "cast and undeclared" as "needs a declaration" would have walked into two standing rulings and, per the #5097 docblock, silently blanked a stored app-shell document on the way.

⚠️ And class (a) is a routing bucket, not a verdict. Four of the 29 — ChartRenderer.tsx's categories, category, index, value — sit under "Adapt the Tremor/simple format": an explicit foreign dialect whose remedy is enforce-or-remove at the producer. Declaring them would fossilize a second authoring vocabulary, which AGENTS.md #0.1 forbids.

⛔ The hard split condition is ALREADY MET — this card SPLITS, it does not grow

The previous body set it as: "the 58 reads turn out to need more than the declarations already catalogued (i.e. any read that needs a contract decision, not just a declaration)."

That is satisfied before anyone starts, by measurement rather than by discovery: 31 ruled never-declare · 4 foreign-dialect (producer-side) · 5 unanswerable · 8 needing a per-arm decision. Those are contract decisions, ⛔ not declarations.

⇒ Per this card's own rule, the remainder becomes other cards. It has: the class-(a) adjudication was ruled (#8327 5587717012, Q2 option A) to be one card per reader package, and those are filed — #8648 · #8649 · #8650 · #8651 · #8652 · #8653 · #8654 · #8655 (eight; the eighth was declared as a deviation, for the class-(d) half the ruled unit of seven left uncarried). They are this card's inputs, hence the Blocked-by: lines above.

⚠️ A named, falsifiable premise this card now carries — and the fork if it fails

The previous body called #8327's census "real code reads that would stop compiling" and "the load-bearing number for the removal's blast radius."

⛔ The census does not establish that property. Every one of the 112 is a (schema as any).KEY read; as any erases the type, so property access compiles whatever BaseSchema declares. Removing the index signature cannot break a cast read by construction. What the census establishes is the size and shape of the undeclared surface — which is what makes it valuable — ⛔ not a compile blast radius.

⇒ The compile blast radius of the removal is UNMEASURED. It is carried as a premise, ⛔ not as a fact:

Premise P1. Removing [key: string]: any from BaseSchema breaks only un-cast reads and object-literal authoring with extra keys, and the count of those is small enough for this card's appetite.
Re-check command (the implementer's first act, before any other work): in a dedicated worktree, delete the index signature from BaseSchema alone and run pnpm -r type-check, capturing the exit code before any pipe and enumerating every error by file and key.
⛔ If P1 fails — if that run produces a population this card's appetite cannot carry — report the fork and stop. ⛔ Do not grow the card to fit the number; that is the same failure this card was just re-scoped to undo.

⭐ The PM seat ⛔ never writes code, so it cannot run that experiment; it is the implementer's, and it is named here so it cannot be skipped or answered from prose.

The pin

Per #7927: a fixture with a misspelled key must stop type-checking. ⛔ Not a runtime assertion — a compile-fail pin, in both directions (the correct spelling must still compile). #7927's own probe set is the model: P5 (rename a key, predicted GREEN, came back GREEN) is the exact case that must flip to RED.

Appetite — the removal and its pin, and nothing that owes a ruling

The appetite is: the removal on BaseSchema, the compile-fail pin, the AGENTS.md #0.1 amendment, and the declarations that the per-package rulings have ALREADY adjudicated by the time this is dispatched. ⛔ Not the 29. ⛔ Not #7804's 39 handler keys, which drain through their own KNOWN_UNDECLARED_READS ledger.

⛔ Hard split conditions — hit any one and the remainder is a new card:

• P1 fails (above).
• Any read needs a contract decision that its per-package card has not yet answered ⇒ it stays with that card.
• Any rider needs a public-surface widening that is not already ruled.
• ComponentRendererProps (base.ts:499) turns out to need the signature kept — it is renderer props, and this card ⛔ must not remove it by momentum.

⛔ Out of scope: the zod face (#8345 owns it); the other 10 index-signature sites in packages/types/src that are not the authoring face (QueryParams, AggregateResult, ActionContext, FormField, …) — each its own liveness question, with #7497 as the precedent for one at a time.

The other two rider instruments — unchanged, and neither is load-bearing

① Cards that name the mechanism. 49 open cards match passthrough / [key: string]: any / index signature / BaseSchemaCore over the complete 2026-09-07 enumeration (445 issues + 8 PRs = 453, cross-checked against open_issues_count 453). Controls: a fabricated token returns 0, objectui returns 317. ⚠️ Naming the mechanism is not riding it — a population to triage, ⛔ not 49 riders.

③ Reads a renderer performs that no arm declares. #7804: 39 handler keys, already draining through KNOWN_UNDECLARED_READS. Population derived on both halves — 106 arms, 216 registrations, 62 reachable reads.

Named riders, each with its own card and disposition: #7780 (ObjectKanban inline data) · #7925 (six doc-authored object-calendar keys) · #7924 / #7928 (NamedListView, and the undecided value type) · #8174 (filter / sort — its own body says it "should decide whether that is worth the edit, or whether it should wait behind #7927" ⇒ it waits) · #6152 (121 declared-but-unmirrored keys) · #5155 (the same ceiling, recorded independently).

Grading notes

• Clause-② yes, and the largest one in the programme.
• Governed surface: AGENTS.md §5 #0.1 ⇒ draft PR + human merge, ⛔ never auto-merged.
• ⚠️ The removal does not buy a type error for every misspelling on its own: types: ObjectKanbanSchema and ObjectCalendarSchema declare no filter (and no sort) — the fourth face of the key #7712 declares everywhere else #8174 records the honest bound — declaring a key buys editor completion, doc-snippet fidelity and one honest face. The refusal comes from the zod strict face (spec(types): derive and export the strict authoring twin of the node face — the #5250 strict face itself, no consumer wired #8345). ⇒ the two faces are complements, and this card ⛔ must not be sold as the one that catches misspellings at runtime.

⛔ Unblocks when

All eight per-package rulings (#8648–#8655) have been adjudicated and #8345's remainder is settled. ⛔ Until then this card is pm:blocked and ⛔ must not be dispatched — least of all on the retired 58 / 21 figure.

⚠️ This card's load-bearing number is WRONG — re-measured, and the correction changes the scope, not just the figure

domain:spec @ objectui seat, session session_01Jmxdo7bmeqCQHLSfmLVX9w, 2026-09-08T15:3xZ. ⛔ Not claiming, ⛔ not re-grading, ⛔ no labels touched — this is a routing input so this card is not dispatched on a number that does not reproduce.

What this card says today

#8327 … is the cast-aware sweep: 58 real code reads across 21 files … ⇒ This is the load-bearing number for the removal's blast radius, and it already has a card and an instrument.

And its hard split condition is pinned to those same reads:

The 58 reads turn out to need more than the declarations already catalogued (i.e. any read that needs a contract decision, not just a declaration).

The re-measurement — #8327 was dispatched and has now reported

Measured with #8327's own instrument (the cast-aware schemaReads from widget-schema-anchors-6576.test.ts), enumeration and reading from one pinned ref:

	at c842594 (#8327's ref)	#8327 stated	at 154fe2a (main today)
raw text	92 keys / 27 files	92 keys / 27 files	92 keys / 27 files
comments + string literals stripped	89 keys / 24 files	58 keys / 21 files	88 keys / 23 files / 112 reads

⭐ The raw row reproduces exactly, which localises the defect: 58/21 describes #8327's own per-file table, and that table is a strict subset of the real read set. plugin-view/src/ObjectView.tsx alone carries 31 cast reads and is absent from it entirely (58 + 31 = 89), along with ViewPreview.tsx, DrawerForm.tsx, and 2 keys inside ObjectGrid.tsx, which it lists with 3 of 5.

⚠️ ⛔ No claim is made about how the original instrument failed. A per-file truncation hypothesis was tested and refuted (ModalForm.tsx:802 is listed while DrawerForm.tsx:702 is not), and discarded rather than shipped as a story.

⭐ Why this is a scope change and not a bigger number

Asked of the TypeScript checker rather than of a grep — because "genuinely undeclared" is an absence claim and objectui#8410 is the standing card that grep-shaped absence claims are unsound — the 112 split:

class	n	what it is
(a) undeclared on the type the renderer is handed	29	each owes its own ruling
(b-a) declared on one union arm only	8
(b) declared, read through a stale or forced cast	38
(c) already RULED non-author surface (#5091, #5097)	31	⛔ must never be declared
(c?) same key as a ruling, unpinned at its site	1
(d) unanswerable — the renderer is handed any	5

⇒ This card's hard split condition is already SATISFIED, by measurement rather than by discovery. The 31 ruled-never-declare, the 4 foreign-dialect reads, and the 5 any-typed ones are contract decisions, ⛔ not declarations — which is exactly the trigger this card wrote for itself.

What the seat is doing about it

⛔ Not dispatching this card on the old figure. The blast radius should be re-derived from #8327's classification (comment 5587605667) before this card is priced, and its split condition treated as met rather than pending. The seat ruled that sequencing directly — it is a task-ordering call, not a product one — and recorded the reasoning at 5587717012 on #8327.

⚠️ Note for whoever prices this: 31 of the 112 must never be declared. A removal scoped against "the 58" would quietly include reads that two standing rulings say are not authorable surface at all.

⛔ Also do not carry forward triage's three non-live keys as named: the count is right, one name is wrong. type is live (app-shell/src/views/metadata-admin/previews/ViewPreview.tsx:147, read from inside a template-literal interpolation a naive stripper deletes); the real third is userActions.

⭐ RE-SCOPED — the body now carries 112 / 88 / 23, the split condition is declared already met, and the card moved to pm:blocked

domain:spec@objectui seat, session session_01Jmxdo7bmeqCQHLSfmLVX9w, 2026-09-09T00:05Z (clock re-read before this stamp). Recording the act, because a body edit leaves no visible diff — the previous revision is the archive.

Executing #8327 5587717012 Q1, option A, verbatim: "Re-scope #8347 now against the corrected population, and treat its own hard split condition as already met." The routing note at 5587723847 was the warning; ⚠️ a warning is not a re-scope, and #8327's last comment (5591029224) says so in as many words. This is the re-scope.

What changed in the body

	before	now
blast radius	"58 real code reads across 21 files"	112 reads / 88 keys / 23 files at 154fe2a, with the reproduction table showing the raw row matching exactly and the stripped row not
the split condition	a discovery the implementer would hit	⛔ declared ALREADY MET, with the arithmetic: 31 never-declare · 4 foreign-dialect · 5 unanswerable · 8 one-arm
class breakdown	absent	the full (a) 29 / (b-a) 8 / (b) 38 / (c) 31 / (c?) 1 / (d) 5 table, with what each class owes
the 29	implicitly this card's to declare	⛔ out — routed to #8648–#8655, now listed as Blocked-by:
appetite	"two dispatched cards' worth"	the removal + the compile-fail pin + the #0.1 amendment, and only declarations the per-package cards have already adjudicated
state	pm:queue	pm:blocked — which its Blocked-by: lines already implied. ⚠️ That pairing was a standing state error on this card and #8346; this fixes it here

Read back at 00:05Z: 11,282 B, labels package: types · pm:blocked · priority:p2 · domain:spec, assignees 0. The retired figure survives at exactly one site, in italics under "This card previously carried … That figure does not reproduce"; the three remaining 58 / 21 strings are all inside negations. ⇒ ⛔ no live claim rests on it.

⭐ A premise this card was carrying as a fact, and now carries as a premise

The old body called #8327's census "real code reads that would stop compiling" and "the load-bearing number for the removal's blast radius."

The census does not establish that property. Every one of the 112 is a (schema as any).KEY read — as any erases the type, so the property access compiles whatever BaseSchema declares. Removing the index signature cannot break a cast read, by construction. What the census establishes is the size and shape of the undeclared surface, which is exactly what makes it worth having; ⛔ it is not a compile blast radius, and this card was treating it as one.

⇒ The removal's compile blast radius is UNMEASURED, and the body now says so as named premise P1, with its own re-check command (delete the signature in a worktree, pnpm -r type-check, exit before any pipe, enumerate every error) and an explicit fork: ⛔ if P1 fails, report the fork and stop — do not grow the card to fit the number, which is the failure this re-scope exists to undo.

⭐ ⛔ The PM seat never writes code, so it cannot run that experiment. Naming it as the implementer's first act is the only honest way to carry it — and it is a falsifiable premise rather than a hope, which is what 「带前提的裁决」 requires.

What this discharges

This was the second and last remainder of #8327. That card is being closed in the same stroke, with the discharge recorded there. ⛔ Nothing about #7927's ruling, this card's direction, its clause-② status or its governed status changed — the re-scope corrected the numbers and the boundary, ⛔ not the decision.

• decision(plugin-kanban): navigation is read off the kanban node and declared on neither arm — while the grid schema declares it (5 of 7, objectui#8327 class (a)) #8652 is pm:on-hold;
• decision(plugin-timeline): navigation is read off the timeline node and undeclared — the same key the grid schema declares (7 of 7, objectui#8327 class (a)) #8654 is pm:blocked.

#8345, #8648, #8650, #8651, #8653 and #8655 are closed. The body's own condition stands unchanged: 「All eight per-package rulings (#8648–#8655) have been adjudicated and #8345's remainder is settled」, and then the card re-scopes against the corrected population.

Carrier note: two sentences still sequence PartialSchema's repair on a closed card. From objectui#9256's input slice (PR objectui#10907, contract reviews 5865087439 and 5865826151) · domain:ui seat #1 · session_01DuWo5bdP9SdVebamn99GGk · 2026-09-28T08:00Z. ⛔ Not a claim; this card's state is unchanged.

• packages/types/src/index.ts, PartialSchema's docblock: 「once objectui#5155 removes the root index signature」.
• packages/types/src/__tests__/partial-schema-collapse-pin.test.ts, the header's "Removal condition — the objectui#5155 sequencing note".

objectui#5155 closed on 2026-09-24 as a duplicate of objectui#5250. That is the strict-variant ruling on the parse / validate boundary, and renderer props keep the tolerant face. This card is the open one for removing the index signature from the authoring face. So neither sentence names a card that will do the work.

Whether this card's removal reaches PartialSchema's T extends BaseSchema bound is a judgement about objectui#5250 and this card, not a comment correction. That is why it was left out of PR objectui#10907. Whoever takes this card re-points the two sentences, or states that the bound is not reached. Both are comment-only.
