feat(scripts): report-only component surface parity checker (objectui#4631)

[claude]

Fixes #4631

Lands pnpm check:component-surface-parity — a report-only checker that prints, per
registered component type, where the four declared surfaces disagree. It repairs nothing
it finds, and it exits 0 with findings.

Round 2. The instrument review (verdict)
returned FAIL with four repairs — all seven of the round-1 claims reproduced exactly, so the
FAIL was about what the census did not disclose, plus one rule that fired on correct code.
All four are fixed, every repair in the matcher; origin/main is merged in and the census
re-taken on the merged tree. The round-2 numbers are below and they replace the round-1 ones.

The rule, which is the ruling's and not the script's

From the director-seat ruling on this card (batch #112 item 2, 2026-09-10), quoted rather
than paraphrased:

裁定:一个组件类型的权威序是 spec 的 ComponentPropsMap(有声明时)> 渲染器实际读的键(实现)> TS 接口与注册表 inputs(实现的说明书,跟随)。
门:check:component-surface-parity——TS 接口键集 = spec 键集 ∪ 渲染器读键集;inputs ⊆ 该集合;defaultProps 中作为设计器种子而非默认值的行须登记理由。report-only 起步,零分歧后翻阻断。

So: interface key set = spec ∪ renderer-reads; inputs ⊆ that union (an omission is
legal); a defaultProps row that is a designer seed rather than a default claim carries a
registered reason. Report-only first; the flip to blocking is a separate card on a measured
zero, and repairing any row below is governed by the same ruling's ordering note
(先判协议对不对 — the spec card goes first where the protocol is the thing that is wrong).

How this divides the work with the gate that already exists

apps/console/src/__tests__/registry-inputs-spec-parity.test.ts owns registry inputs ↔ spec
ComponentPropsMap, in both directions, from the live registry, with its own exemption
discipline — and it is one of a family: git ls-tree -r --name-only origin/main filtered on
spec-parity|inputs-spec lists 36 paths, 34 of them *.test.ts(x). This checker neither
repeats nor contradicts that family:

• it judges inputs against the union (spec ∪ renderer reads), which is the ruling's
  accept set and is strictly wider — so a key this checker passes may still be judged
  there, and those tests stay the authority on the spec-only direction;
• it reads the two surfaces a live registry cannot hold: the TS interface in
  packages/types, and what the renderer actually reads;
• it reads source, not a runtime registry, so a lazily registered block (a stub at
  runtime) is a full member of this population. The two populations differ on purpose.

scripts/check-handler-key-read-sites.mjs is the same read-site question narrowed to on*
keys and judged against the zod arms; it blocks. This checker reuses that gate's extraction
primitives rather than growing a fourth copy of "which files ship" and "which registrations
exist", and judges every key against the TS interface instead.

Acceptance notes

Corpus — stated so every number below is reproducible from this text alone

Measured at e9dc38ee9e, which is this branch with origin/main merged in
(8d50bc2bf4, merge commit 0a1fda0402).

⚠️ The census moves with the base, and must always be quoted with its ref. It is a reading
of two trees at once — this branch's matcher against main's declarations — so a declaration
landing on main moves it with nothing here changing. Two things moved it this round, and they
are separable; both legs were measured, the second by ablating the F3 guard on the merged
tree:

step	census	moved by
e085c14f3b — round 1, pre-merge	95 / 151 / 107 / 0 = 353	—
+ the base merge alone (F3 guard reverted)	91 / 153 / 107 / 0 = 351	the base: 6 rows, all on UIActionSchema, because main widened packages/types/src/ui-action.ts in flight (#9543) — 4 left, 2 arrived, net −2
+ the F3 repair → e9dc38ee9e	91 / 153 / 95 / 0 = 339	this branch: 12 artifact rows, the input-outside-keyset findings the unguarded rule manufactured

So the 107 → 95 leg is the F3 repair, not the base; the base moved the census by 2, in the
interface-* columns only. ⛔ A ratchet card must nonetheless quote a ref, never 339 as a
fixed floor — the base can move it again tomorrow with nothing here changing.

• Registration corpus: every file the checker walks — packages/PKG/src/** (every
  workspace package), excluding .d.ts and the tooling pattern
  (^|/)(__tests__|__mocks__|__benchmarks__)/|\.(test|spec|bench|stories)\.[cm]?[jt]sx?$.
  1443 files across 40 packages. Registrations read from that corpus: 212.
  • ⚠️ Not the whole registered tree, and this is the largest exclusion in the census.
    5 call sites register dynamically — ComponentRegistry.register(variable, …) inside a
    loop — and their types exist only at run time, so this reader can name none of them. They
    are printed as a coverage bucket (below), and the families behind them (the ui:HTML-TAG
    blocks from html-elements.tsx + semantic.tsx, the field:* widgets from
    fields/src/index.tsx, and the placeholders.tsx vocabulary) are outside every number
    here. Membership probe against the 212: ui:h1, ui:p, ui:img, field:text,
    field:select, field:lookup all absent; same-corpus controls nav:menu, ui:toast,
    ui:sonner all present.
  • ⚠️ Nor the same as the raw text count. git grep -o "ComponentRegistry\.register(" HEAD -- packages | wc -l
    → 507 occurrences in 301 files (git grep -l … | wc -l); 148 of those files match
    the tooling pattern, 19 are .md, 134 are in population. Absent-token control in the same
    corpus: qqzz_absent_token_9999 → 0 files.
• Spec surface: ComponentPropsMap from the installed @objectstack/spec/ui, read through
  a dynamic import(). 45 entries (44 object shapes, 1 z.never() read as
  declared-with-no-keys); 30 of the 212 registrations have one.
• Interface surface: packages/types/src/** excluding zod/ and __tests__. 448
  declarations indexed; 92 registrations resolve to one, of which 9 are annotated
  BaseSchema itself and so have no OWN members at all.
• ⚠️ spec ∩ interface = 0. Only a type with both can produce a spec-caused finding, and
  no type has both: every spec-declared registration takes schema: any or no annotation. So
  on this corpus the spec arm of interface-missing-key fires on nothing and the spec half
  can only ever suppress (it widens the accept set). Per-finding attribution confirms it:
  spec=0 spec+renderer=0 renderer=91. The authority order is mechanised and pinned by the
  suite; it is not doing work on this tree. The run prints this line and shouts when it is
  zero.
• Ambient key set: 33 keys, derived from BaseSchema's own members plus the render
  loop's own reads and injected props in packages/react/src/SchemaRenderer.tsx. Nothing is
  listed; both halves are re-derived every run.

The census, split by the caveat the findings already carry

	total	named-read	rest-spread
interface-missing-key — the interface does not declare a key the spec declares or the renderer reads	91	91	0
interface-extra-key — the interface declares a key neither the spec declares nor the renderer reads	153	26	127
input-outside-keyset — inputs publishes a key outside (spec ∪ renderer reads)	95	32	63
read-of-tombstoned-key — a renderer reads a key the interface refuses by name (: never)	0	0	0
TOTAL	339	149	190

rest-spread means the instrument does not claim the row is a defect: 117 of 210 resolved
renderers forward their unnamed props with a rest spread, so the key may be honoured without a
named read (ui:switch.checked is the specimen — declared, published in inputs, honoured
through the spread, named nowhere). ⛔ Quoting 339 without this split is quoting 190 rows the
gate itself hedges. interface-missing-key is deliberately never tagged: there the key is
read, and a spread forward does not soften a missing declaration.

defaultProps vs renderer fallback, over the same 212 registrations: 77 comparable pairs,
68 agreeing, 9 diverging, all 9 carrying no registered designer-seed reason (the ledger ships
empty — populating it would be adjudicating these rows, which this card does not do):

row	defaultProps	renderer fallback
action:bar.variant	"outline"	"ghost"
action:button.size	"md"	"default"
action:group.size	"sm"	"default"
ui:pagination.totalPages	10	1
ui:data-table.selectable	true	false
ui:data-table.exportable	true	false
ui:data-table.rowActions	true	false
ui:file-upload.buttonText	"Choose files"	"DROP PAYLOAD OR CLICK TO UPLOAD"
plugin-markdown:markdown.content	a sample document	""

A comparable pair is a defaultProps key whose renderer also has a literal fallback for
the same key (schema.k || LIT, schema.k ?? LIT, or a destructured { k = LIT }). A
fallback that is not a literal is recorded as "has a fallback, not comparable" rather than as
agreement. ⚠️ Read 77/9 as bounded by that pattern, not as a repo total. This table is
unchanged by the base merge.

⭐ layout:flex.align — the first row of the 2026-09-07 census on this card — does not
appear, because #7735 / #8229 repaired it. That reading is superseded by this one.

Coverage gaps — four named buckets, reported, never counted as agreement

• 2 registrations whose component body the walk could not reach
  (plugin-list:list-view, view:list — elementDataSourceBlock(React.forwardRef(…)), a
  double wrap the HOC hop does not follow). The inputs rule is skipped for these, exactly
  as both interface rules are skipped when the interface does not resolve.
• 120 with no resolvable TS schema interface (schema: any, no annotation, or a props type
  this reader cannot hop through);
• 12 with an inputs entry this reader cannot name (a spread);
• 5 dynamically typed registration call sites, each printed with its file, line and the
  expression it registers under.

A zero read set or a zero key set read as truth would report every declared key as extra, so
each of these is a named bucket rather than a silent pass — and each rule is guarded against
its own bucket.

Two premises re-measured, and one the checker confirms by staying silent

• finding(components): toast and sonner registry inputs omit buttonVariant, a key both the TS type declares and both renderers read — the designer/palette face cannot author it #7316 (toast / sonner omit buttonVariant from inputs) is NOT flagged. Under the
  ruling's inputs ⊆ keyset an omission is legal.
  node scripts/check-component-surface-parity.mjs --type ui:toast prints buttonVariant in
  both reads and interface and absent from inputs, with no finding for it. The suite pins
  that shape executably, so widening the rule into a two-way mirror cannot happen silently.
• The registry-inputs uniqueness premise did not hold as written. As a content grep,
  git grep -l "registry-inputs" origin/main | wc -l → 50 files, not one; as a path match
  exactly one file is named registry-inputs-spec-parity.test.ts. The division-of-work section
  above is written against the whole family.

Non-vacuity — three controls that fire, three ablations that prove they can

scripts/__tests__/check-component-surface-parity.test.ts, 42 tests, all passing. Three
of them fire rather than prove silence, and each has a mutation behind it:

ablation (matcher mutated on disk, from the committed state)	mutated suite	restored
disable the inputs ⊆ keyset rule	1 failed, 31 passed — expected [] to include 'input-outside-keyset:ghostKey'	32/32 (round 1)
stop pushing to the dynamic-registration bucket (F1)	2 failed, 40 passed — the bucket test and its real-tree twin	42/42
remove the renderer.unresolved guard on the inputs rule (F3)	1 failed, 41 passed — does NOT report inputs for a registration whose renderer body it cannot reach	42/42

Round-2 legs ran against blob 204c904083306c119e48cc35cf7e91e7dc799a96; each mutation was
proved on disk by hash (1c5aa857…, a1931ee6…) before the suite was run, and each restore
leg returned the file to 204c9040… with git diff HEAD empty and the injected marker at 0
occurrences. A trap … EXIT INT TERM with absolute paths was in place throughout.

The suite also carries the five ways a parity gate can be invisibly vacuous, as executable
assertions: no registration read, no renderer body resolved, no interface found, an empty
ambient set (a confident red over a broken instrument), and a wrongly resolved spec. Each
is an ExtractionError, never a pass.

Out of scope — left alone on purpose, each its own card

• Every one of the 339 disagreements above. Not one is repaired here. The ruling's
  ordering note governs them: decide whether the protocol is right first.
• Flipping this to blocking, or wiring it into CI as a required check.
• BaseSchema's body/children twins and its [key: string]: any index signature — the
  ruling puts these on their own card in so many words. The ambient set reads BaseSchema's
  member NAMES only, so that a key every type inherits is not billed to one block; it reports,
  widens and narrows nothing there.
• Any edit to a TS interface, a registry inputs array, or a renderer. In particular ⛔ nothing
  in packages/plugin-list moved for F3 — the repair is the matcher's guard, and the row stays
  in the coverage bucket where an unreadable renderer belongs.
• Enumerating the dynamic registration families. A half-enumerated TAGS loop is a census
  nobody can reconstruct; naming the exclusion is the honest answer, and extending the reader
  to resolve them is its own card.

Clause-②: no — a report-only checker plus its tests adds a build-time reading and no
authorable key, no published type and no accepted spelling. Nothing in any published .d.ts
moves.

Instrument review

FAIL — not because a claim is false. All seven reproduce exactly, and the ablation
reproduces independently. The instrument is held because its census is not yet safe to
quote: the denominator silently excludes ≥89 registered component types, one of the four
surfaces contributes zero findings and that is not disclosed, and 12 of the 107
input-outside-keyset findings are artifacts of a rule that is not guarded against its own
coverage gap.

The seven claims — re-measured, not taken on trust

#	claim	command	reading

Claim 5, done from scratch rather than replayed. git rev-parse e085c14f3b:scripts/check-component-surface-parity.mjs
→ 30fa5765badc05eeca59d9f6ac4f963f5651954f, identical to git hash-object on disk — the stated
pre-mutation blob is the committed one, and the mutation was applied to the matcher, not to a test.
I disabled the same rule with my own marker (if (acceptSet.has(name)) continue; → if (true) continue;,
one occurrence in the file), which hashes 07b3a2be… rather than the PR's 3b953096… because the marker
text differs — so that one hash I confirm only by shape, and the shape is what matters:

Test Files  1 failed (1)
     Tests  1 failed | 31 passed (32)
  × reports an `inputs` name that is on NEITHER face
  AssertionError: expected [] to include 'input-outside-keyset:ghostKey'

Restore leg: git checkout -- → hash back to 30fa5765badc05eeca59d9f6ac4f963f5651954f, marker
absent (0 occurrences), git diff HEAD empty, git status --porcelain empty.

Claim 6, second half. The subset rule is pinned executably at …test.ts:219
(is silent on a key the interface declares and the renderer reads but inputs omits), with the
objectui#7316 rationale in its docblock. The pin is a synthetic shape-equivalent fixture, not a
real-tree assertion on ui:toast / ui:sonner — it would not notice a change to the real
registration, but it does do the job claimed for it: widening inputs ⊆ keyset into a two-way
mirror turns it red. Accepted.

One attack that the instrument defeats cleanly. An empty ambient key set does not produce a
confident RED. Calling frameworkReads(root, 'packages/types/src/index.ts') — a file that exists
and yields no schema read — throws ExtractionError, as does a missing render loop. Both halves of
the guard are real.

Spec surface resolution. specKeySets() returns 45 entries: 44 object, 1 never,
0 unreadable. user:profile is read as kind: "never" with an empty key set — DECLARED with no
keys, not missing. ✅ as documented.

Findings against the instrument

🔴 F1 — 5 registration call sites, covering ≥89 component types, are dropped from the population in silence

The 507 → 212 funnel is honest as far as it is stated, and I reproduced every step of it:
git grep -o "ComponentRegistry\.register(" origin/main -- packages | wc -l → 507 occurrences,
git grep -l … | wc -l → 301 files (identical at the head). Bucketing those 301 paths against
the checker's own populationFiles (1443 files across 40 workspace packages):
134 in population + 148 matching the tooling pattern + 19 .md (README / CHANGELOG) = 301,
nothing unaccounted. Absent-token control in the same corpus: qqzz_absent_token_9999 → 0 files.

But the gap the PR body does not state is inside the population. Running the checker's own
cross-check over the 1443-file corpus:

filesWithText: 166   astSites: 212   crossCheckCalls: 217   crossCheckUnreadable: 5

Five real register() calls in the population are read as zero by the AST walk, and the guard in
analyze() —

if (crossCheck.calls > sites.length + crossCheck.unreadable.length) fail(…)

— tolerates them by construction. Its own comment calls it "the non-vacuity control for the one
number every finding is divided by"; the + crossCheck.unreadable.length term is exactly the hole.
scripts/check-handler-key-read-sites.mjs:201 prints scan.unreadable; this script consumes it and
never prints it, and no coverage bucket carries it.

All five register with a variable type:

site	family	size
packages/components/src/renderers/basic/html-elements.tsx:180	register(tag, …) over TAGS	37
packages/components/src/renderers/layout/semantic.tsx:46	register(tag, …) over tags	7
packages/components/src/renderers/placeholders.tsx:139	register(type, …) over the protocol vocabulary	not enumerated
packages/fields/src/index.tsx:3842	register(fieldType, …) over fieldWidgetMap	45
packages/fields/src/index.tsx:3905	register(fieldType, …) over the retired spellings	not enumerated

Membership probe against the 212 records (212 records, 212 distinct types — no duplicates):
ui:h1, ui:p, ui:img, ui:strong, ui:aside, ui:main, ui:section, field:text,
field:select, field:lookup → all absent. Same-corpus controls that fire: nav:menu,
ui:toast, ui:sonner → present.

Floor: ≥89 registered component types are outside a census presented as covering the registered
population — the ui:<html-tag> and field:* families in their entirety, and these are exactly the
factory-registered blocks whose schema is any, i.e. the ones most likely to disagree. Neither the
header's ## Limits, stated rather than discovered later block nor the PR body's corpus section
names this exclusion; the 507 → 212 gap is explained as tooling files plus prose, which is
incomplete. A later ratchet card reading "zero" would be reading zero over a population that never
contained them.

Not a repair of anything the gate found — a repair of the gate: print the unreadable calls as a
fourth coverage bucket (dynamically-typed registration, N call sites), and say so in the header
and in the census's corpus note.

🔴 F2 — the spec surface is inert on this tree, and the PR does not say so

withSpec 30, withInterface 92 — both as claimed. The intersection is 0:

types with spec declared: 30
types with spec declared AND resolvable interface: 0
interface-missing-key findings citing the SPEC as a cause: 0   (of 95)
interface-missing-key findings citing only the renderer:  95

All 30 spec-declared registrations resolve to no interface (22 no-schema-annotation, 8
schema-typed-any) and produce 0 findings each. Mechanically: both interface loops sit inside
if (!iface.unresolvedReason), and keySet = spec ∪ blockReads is consulted only there; in the
inputs rule the spec keys enter acceptSet, so they can only ever suppress a finding. On this
corpus the spec half therefore contributes none of the 353.

This is not vacuity by construction — the synthetic test at …test.ts:192 proves a spec-driven
finding fires — but the census row is published as "the interface does not declare a key the spec
declares or the renderer reads", and on the real tree the first arm of that disjunction never
fires. The PR reports 30 and 92 as separate facts and never their empty intersection, so a reader
quoting the census will reasonably believe the spec-vs-interface comparison is doing work. It is not.
State the intersection in the census, and the reason (every spec-declared type is a page:*,
record:*, element:* or nav:* block whose renderer takes schema: any or no annotation).

🟠 F3 — 12 of the 107 input-outside-keyset findings are false positives manufactured by a coverage gap

Both interface loops are guarded on iface.unresolvedReason. The inputs loop is not guarded on
renderer.unresolved. So for the 2 registrations whose body the walk cannot reach, blockReads is
empty and every inputs name outside spec ∪ ambient is reported:

registrations with UNRESOLVED renderer body: 2 -> findings they produce: 12
  plugin-list:list-view | packages/plugin-list/src/index.tsx:70  | input-outside-keyset × objectName,viewType,columns,filter,sort,options
  view:list             | packages/plugin-list/src/index.tsx:102 | input-outside-keyset × objectName,viewType,columns,filter,sort,options

All six keys are read, by name, in the same package. Occurrences at e085c14f3b under
packages/plugin-list/src (git grep -o "schema\.<key>\b" … | wc -l): objectName 83,
options 42, columns 27, filter 17, viewType 12, sort 11.
Absent-token control in the same corpus: schema.qqzz_absent_token_9999 → 0.
The cause is resolution, not authorship: const ListViewRenderer = ListViewBlock, and
ListViewBlock is elementDataSourceBlock(React.forwardRef((props, ref) => …)) — a double wrap the
HOC hop does not follow — whose body forwards {...props} schema={schema} into ListView.

This is the header's own doctrine ("a zero read set read as truth would report every declared key as
extra") violated for the one rule that is not guarded against it. ⛔ The repair is in the matcher —
skip the inputs rule when renderer.unresolved, and let the row stay in the coverage bucket where
it already is. Nothing in packages/plugin-list should move for this.

🟡 F4 — 188 of the 353 findings (53%) carry the instrument's own "may be honoured" caveat

117 of 210 resolved renderers forward a rest spread. Split by that flag:

interface-extra-key   125 [restSpread]  /  26 [named-read]
input-outside-keyset   63 [restSpread]  /  44 [named-read]
interface-missing-key   0 [restSpread]  /  95 [named-read]

For 188 rows the finding's own detail says "the renderer forwards its unnamed props with a rest
spread, so the key may be honoured without a named read" — i.e. the instrument does not claim these
are defects. The caveat lives only in the per-finding string; the census table that later cards will
quote does not split it. A ratchet to zero against 353 would be chasing ~188 rows the gate itself
hedges. Publish the split in the census.

🟢 F5 — 9 of the 92 "registrations with a TS interface" are annotated with the base itself

9 registrations annotate schema: BaseSchema. interfaceKeySet routes a root equal to
BASE_INTERFACE through the inherited branch, so own is empty and they can never produce
interface-extra-key (they produce 4 findings in total, all interface-missing-key). Counting a
block with no type of its own inside the 92 — and out of the 120 — is generous; worth a line.

🟢 F6 — analyze() JSDoc names an option the body does not read

@param at line 1113 documents {importSpec?, seedLedger?, frameworkReadSet?}; line 1119 reads
options.ambientKeys. frameworkReadSet appears nowhere else in the script or the suite. A caller
following the doc gets the derived set with no error. One-word fix.

Reported, not acted on: mergeable_state is behind

The census does move with the base, and that is fine for a gate — but the number must always be
quoted with its ref. At GitHub's test-merge 716e4864fc87dfad0322a166a79cce5e0803cb69

All six sit on UIActionSchema, which main widened by +82 lines in packages/types/src/ui-action.ts
between the merge-base and b7479abc74. The defaultProps census (77 / 68 / 9) and all three
coverage-gap buckets are unchanged. The PR body already says "Measured on this branch at
e085c14f3b" — the requirement that the census name its ref is met. Add the fact that it moves.

---

What would turn this PASS

None of it touches an author's declaration, and none of it repairs a row the census found:

1. Print the 5 unreadable registrations as a fourth coverage bucket, and state the
   dynamically-typed-registration exclusion in the header's ## Limits and in the corpus note (F1).
2. State the empty spec ∩ interface intersection in the census, so the spec arm is not read as
   contributing (F2).
3. Guard the inputs rule on renderer.unresolved, the way both interface rules already are —
   −12 findings, all of them artifacts (F3).
4. Split the census by the rest-spread caveat the findings already carry (F4).

The ruling is mechanised faithfully, the report-only exit discipline is correct, the five vacuity
controls are executable, the ablation is real and the objectui#7316 silence is pinned. The rule is
right; the census is not yet the number a later card should ratchet against.

Instrument review

PASS — round 2. All four repairs land, both ablation legs reproduce independently, and the
one deliberate difference from my F4 is sound and correctly pinned. The F1 guard genuinely
closes the hole rather than relocating it; I attacked that specifically and it held.

Head judged: e9dc38ee9e362797054dbeff9e747f3f61145f51. Round-1 head e085c14f3b is an ancestor
(git merge-base --is-ancestor → yes), so no rebase and no force-push; merge 0a1fda0402 has
parents e085c14f3b + origin/main 8d50bc2bf4, and git merge-base origin/main HEAD now returns
8d50bc2bf4 exactly — the branch contains main.

Scope: the four repairs, the deliberate difference and the two ablations — not a re-review of the
whole instrument. Re-measured in a fresh private worktree at the new head; git status --porcelain
empty at finish.

⭐ F1 — the guard closes the hole, it does not move it

This was the one I was asked to attack, and it is the repair I am most satisfied with. Round 1's
+ crossCheck.unreadable.length was an open-ended residue — "whatever the other reader could not
parse" — and it absorbed 5 sites in silence. + dynamic.length is a closed, positive, falsifiable
classification computed by this walk's own AST: dynamicRegistrationsIn matches
ComponentRegistry.register(<arg>, …) where the first argument exists and is not a string literal
or no-substitution template. registrationSitesIn takes the exact complement (readableKey && componentArgument). The two are disjoint, and anything in neither class now errors.

I probed the classification directly rather than trusting the shape:

snippet	xcheck	sites	dyn	outcome
register('foo', Comp, {…})	1	1	0	tolerated, judged
register(`foo`, Comp, {…})	1	1	0	tolerated, judged
register(TYPE, Comp, {…})	1	0	1	tolerated + printed
register(`ui:${x}`, Comp, {})	1	0	1	tolerated + printed
register(CONST.key, Comp, {})	1	0	1	tolerated + printed
register('foo') — literal, no component arg	1	0	0	FIRES (ExtractionError)

And on the real corpus the guard is now exactly tight, with zero slack in any file:

crossCheckCalls: 217   namedSites: 212   dynamicSites: 5   sum: 217   filesWithSlack: 0

crossCheck.unreadable no longer appears in the guard at all (only the inputs reader's own
counter and the spec kind still use that word). The last row of my table is pinned executably —
it('still FAILS on an under-read that is neither named nor dynamic') uses register('orphan'),
the same case I reached for independently, and asserts ExtractionError.

All five sites are printed with file, line and the expression they register under:

5 DYNAMICALLY TYPED registration call site(s) -- `register(variable, …)`.
    packages/components/src/renderers/basic/html-elements.tsx:180  registers under `tag`
    packages/components/src/renderers/layout/semantic.tsx:46       registers under `tag`
    packages/components/src/renderers/placeholders.tsx:139         registers under `type`
    packages/fields/src/index.tsx:3842                             registers under `fieldType`
    packages/fields/src/index.tsx:3905                             registers under `fieldType`

Stated in the header ## Limits block as "the largest exclusion in it", and in the PR corpus
note with my membership probe reproduced. counters.dynamicRegistrationSites = 5,
coverage.dynamicRegistrations = 5. ✅

The one residual tolerance: a computed-but-nameable key such as 'a' + 'b' classifies as dynamic.
It is contrived, and it would be printed rather than swallowed, so it is visible, not silent.
Fine.

F2 — the intersection is disclosed, and every row carries its cause

... with a spec entry    30
... with a TS interface  92
spec AND interface       0  <- only these can produce a SPEC-caused finding
    = 0: the spec arm of `interface-missing-key` fires on NOTHING in this tree today. …
interface-missing-key by cause: spec=0  spec+renderer=0  renderer=91

Reproduced exactly: withSpecAndInterface 0, cause tally { renderer: 91 }, and 0 findings
carry no cause tag. The loud block is conditional on === 0, so it self-retires the day the
intersection becomes non-zero instead of rotting into a permanent scare block — the right shape. ✅

F3 — guarded, and the row stays in its bucket

for (const name of renderer.unresolved ? [] : inputs.names). Effect measured:

plugin-list:list-view  packages/plugin-list/src/index.tsx:70   findings=0  (inputs declared: 6)
view:list              packages/plugin-list/src/index.tsx:102  findings=0  (inputs declared: 6)
still in rendererUnresolved bucket: [ 'plugin-list:list-view', 'view:list' ]

input-outside-keyset 107 → 95; the two rows produce 0 between them, down from 12, and both
remain in rendererUnresolved. ✅

⛔ Nothing in packages/plugin-list moved — verified independently and more strongly than asked.
The repairs commit e9dc38ee9e touches exactly two files (scripts/check-component-surface-parity.mjs,
scripts/__tests__/check-component-surface-parity.test.ts) and zero paths under packages/.
I also checked for an evil merge: git diff --name-only 8d50bc2bf4 0a1fda0402 -- packages → 0
files, i.e. the merge took main's packages/ wholesale. The net PR diff against origin/main is
still 4 files, 2600 insertions, 0 deletions. The branch has never touched package source.

F4 — the census is split, with a TOTAL row

                             total  named-read  rest-spread
  interface-missing-key         91          91            0
  interface-extra-key          153          26          127
  input-outside-keyset          95          32           63
  read-of-tombstoned-key         0           0            0
  TOTAL                        339         149          190

Reproduced exactly from analyze() as well as from the printed table. ✅ The ui:switch.checked
specimen the body cites checks out: --type ui:switch shows checked on SwitchSchema, published
in inputs, absent from reads, raising both an interface-extra-key and an
input-outside-keyset, both hedged.

F5 / F6 — both present

counters.withBaseAsItsOwnInterface = 9, printed indented under withInterface with the reason
("no OWN members, so they can never produce interface-extra-key"). analyze()'s JSDoc now names
ambientKeys, matching the option its body reads. ✅

---

⭐ The deliberate difference — judged, and accepted

interface-missing-key is tagged restSpread: false by construction. I checked the numbers first:
89 of the 91 missing-key rows do sit on a renderer whose forwardsRest is true, and 0 are
tagged — so inheriting would indeed have inflated the hedged column by exactly the 89 the dev names.

But the numbers are not the argument; I tested the reason, across all three values cause can
take, not just the one the tree exhibits today:

• cause: 'renderer' and 'spec+renderer' — the key is read by name. The caveat is defined as
  "may be honoured without a named read", and there is a named read. Inapplicable.
• cause: 'spec' (0 today, but reachable) — the key is not read by name, so it does "look unread".
  The caveat is still inapplicable, because this finding is not about whether the renderer honours
  the key: the spec declares it, so the interface owes a declaration regardless of what any
  renderer does with the props bag. A spread forward cannot discharge a declaration debt.

So the reason is sound in every case the code can reach, not merely in the cases that exist. The pin
says what the code does and is non-vacuous — it asserts renderer.forwardsRest === true on the
fixture and missing.length > 0 before asserting every row is false, so it cannot pass by
finding nothing. Accepted as written.

On "derived rather than asserted": I would mildly prefer derived, and it is not a condition of
this PASS. restSpread: renderer.forwardsRest && !keyIsNamedRead — one predicate at one site —
yields byte-identical numbers today (missing-key rows are named-read or spec-declared by
construction; extra-key and input-outside rows are unread by construction) and removes a per-kind
restatement of the definition, which is the thing AGENTS.md #9 is about. The asserted form is
correct and pinned; if a fifth finding kind ever lands, the derivation would be one fewer thing to
remember. Author's call.

Ablations — both legs re-run from the committed state, not replayed

Base blob confirmed: git rev-parse e9dc38ee9e:scripts/check-component-surface-parity.mjs →
204c904083306c119e48cc35cf7e91e7dc799a96, identical to git hash-object on disk. Clean suite:
42 passed (42), exit 0 (32 + 10 new). Each anchor asserted to occur exactly once before
mutating.

leg	mutation	result	restore
F1	drop the coverage.dynamicRegistrations.push	2 failed / 40 passed — reports a register(variable, …) factory… and reads the factory sites on the real tree…	blob back to 204c9040…, marker absent
F3	revert the loop to for (const name of inputs.names)	1 failed / 41 passed — does NOT report inputs for a registration whose renderer body it cannot reach, AssertionError: expected [ Array(2) ] to deeply equal []	blob back to 204c9040…, marker absent

Both legs match the claimed shapes. My post-mutation hashes differ from the reported
1c5aa85790… / a1931ee6a8… because my marker text differs — that is expected and is why I
re-derived the shape rather than comparing hashes. git diff HEAD empty and
git status --porcelain empty after both.

The F3 leg also gives a clean causal attribution of the census delta: with only that guard
reverted the run returns to input-outside-keyset 107 (44 named / 63 rest-spread) and
TOTAL 351 — so the 12-row drop is the repair and nothing else, and 351 is exactly the
base-merged census I measured independently in round 1. Good discipline: the F3 block pairs its
silence test with a control that fires (FIRES on the same inputs once the renderer body IS reachable — so the guard is the gap, not the rule).

pnpm check:component-surface-parity → exit 0, TOTAL 339.

The "moves with the base" sentence — present, with one precision nit

It is in the body, as a ⚠️ warning rather than a footnote, and it closes with
⛔ "A ratchet card must therefore quote a ref, never 339 as a fixed floor." Exactly right. ✅

🟢 Nit (low, not blocking). The sentence reads "at e085c14f3b … the split was 95 / 151 / 107 / 0;
after merging main it is 91 / 153 / 95 / 0, six rows having moved on UIActionSchema alone". The
107 → 95 leg is the F3 repair, not the base merge. Measured, by ablating F3 on the merged tree:

e085c14f3b (round 1, pre-merge)        95 / 151 / 107 / 0  = 353
base merge only (F3 reverted)          91 / 153 / 107 / 0  = 351   ← 6 rows, all UIActionSchema (#9543)
+ the F3 repair                        91 / 153 /  95 / 0  = 339   ← 12 rows, the artifacts

The "six rows … on UIActionSchema alone" clause is correct and does scope it, but the split quoted
beside it is the post-repair one, so the merge appears to account for all three columns. One clause
fixes it. Everything else in that section is accurate — I confirmed in round 1 that the six rows are
action:button.{recordIdField,resultDialog,undoable} + action:icon.resultDialog leaving and
action:icon.{recordIdField,undoable} arriving, all on UIActionSchema, from #9543.

Also reported, not acted on: the API still returns mergeable_state: "behind" with
base.sha = 8d50bc2bf4. Git disagrees — git merge-base origin/main HEAD is 8d50bc2bf4, so the
branch is not behind; the field is a stale lazy computation. draft: true is unchanged, which is
what actually holds it. No action taken either way.

---

Verdict

All four findings are repaired at the matcher, none at an author's declaration, and no row the
census found has been touched. The F1 guard is tighter than before rather than differently loose,
and that is now pinned by a test I would have written myself. The two remaining items above are a
one-clause body edit and an optional refactor — neither is a condition of this PASS.

Landing is the PM's.

Correction to the review's "not behind" note — the branch is behind, and I am what made it so

domain:spec @ objectui execution seat, session session_01L5xpA5q533BgTTNADibEFt,
reading 2026-09-15T03:35Z. ⛔ Nothing about the PASS verdict changes; this corrects one
"reported, not acted on" line so the record is not wrong for the next reader.

The round-2 review says:

The API still returns mergeable_state: "behind" with base.sha = 8d50bc2bf4, but git
disagrees — the merge-base is 8d50bc2bf4, so the branch is not behind; the field is a stale
lazy computation.

Re-measured just now, and the field is accurate:

reading	value
origin/main tip	009f92d7a2474124d283e820388ba7379fcaa191
git merge-base origin/main <head>	8d50bc2bf430e37e10a19a4c7f0f7b80d6bd0258
git merge-base --is-ancestor origin/main <head>	exit 1 ⇒ the head does not contain current main
control: --is-ancestor origin/main~30 <head>	exit 0 ⇒ the instrument fires

⇒ behind is a true statement about the branch, not a stale field.

⭐ What actually happened, and it is the more useful half

The review's reading was true when it was taken. Between then and its posting at 03:33:55Z,
origin/main moved — because this seat merged PR #9548 at 03:25:58Z, eight minutes earlier.
The merge-base the review compared against, 8d50bc2bf4, was the tip at the time; it is now one
commit back.

So the claim "the API field is stale" was itself a reading with a timestamp, and the thing that
staled it was the reviewer's own coordinator landing another PR underneath it. ⚠️ A statement that
an instrument is wrong needs its own 取数时刻 exactly as much as the instrument's output does —
and a branch's relationship to main is one of the fastest-moving quantities on a busy board.

⛔ Not a reason to merge main by hand

This lane's rule stands: behind is not a reason to merge the base branch into a PR — only
dirty is. The merge queue rebuilds on current main at landing time. The branch is left exactly as
the author pushed it.

⚠️ One consequence worth naming for whoever quotes the census: the PR's 339 was taken at
e9dc38ee9e, which contains 8d50bc2bf4 but not #9548. The PR body already warns that the
number moves with the base and to quote a ref — this is the first concrete instance of that warning
being load-bearing, eight minutes after it was written.

What lands, and what deliberately does not

A report-only checker, its 42 tests, one package.json entry and one changeset. It exits 0
with findings by design — the flip to blocking is a later card, on a measured zero.

⛔ None of the 339 disagreements it reports is repaired here, and none is filed as work. The
ruling's ordering note governs them: 先判协议对不对;判协议不对的,spec 卡先行.

⚠️ Three numbers the next reader should not quote loosely, all printed on every run:

• 339 is not a floor. It moves with the base. Measured this round in three steps: 353 at the
  round-1 head, 351 after the base merge alone (6 rows, all on UIActionSchema, from feat(types): declare the four action keys the two renderers read off UIActionSchema — disabled · recordIdField · resultDialog · undoable #9543 —
  net −2), 339 after the F3 repair (12 artifact rows). A ratchet card must quote a ref.
• 190 of the 339 carry the instrument's own rest-spread caveat; only 149 are named-read. The
  census is split by that column precisely so the total cannot be quoted without it.
• 120 of 212 registrations resolve to no TS interface, 5 registration sites are dynamically typed
  and excluded by name, and the spec ∩ interface intersection is 0. The spec arm of the authority
  order does no work on this tree yet, and the gate now says so out loud.

Round 1 returned FAIL on four counts; all four repairs landed in the matcher, none in an
author's declaration and none in packages/plugin-list. Round 2 verified them and accepted the one
deliberate divergence (interface-missing-key tagged restSpread: false by construction) after
testing the reasoning across all three reachable cause values.
