feat(spec)!: a form view's subform columns are the inline grid column contract, and an identity-only column is judged as the type it renders (#20901)

[objectstack-fleet]

Closes #20901

Clause-②: yes (narrowing)

• FormViewSchema.subforms[].columns references InlineGridColumnSchema (was z.array(z.any())): the card's typed currency + scale column and its zzz_not_a_key column are refused at the view parse.
• defineStack's cross-reference check (packages/spec/src/stack.zod.ts#collectHydratedInlineColumnErrors, called from validateCrossReferences) re-parses a column that declares no type as the type it renders (currency over a currency child field) through InlineGridColumnSchema, on both carriers. The card's identity-only column with scale is refused there with the column schema's own message; there is no second scale rule.
• ADR-0087: D3 entries form-view-subform-columns-closed and inline-grid-column-identity-only-currency-scale-refused; the registry was regenerated after merging a main that carries feat(spec)!: connector-attached sync leaves the connector — syncConfig / fieldMappings retired, mapping gains the connectorSource pull binding (#20281 stage 1) #20903 and fix(objectql,spec)!: a groupBy on a multi-value field and a count_distinct on a JSON-stored field are refused INVALID_FIELD / 400 at the engine aggregate door, on every driver (#20808) #20911.

Evidence at feba1a99bd: pins packages/spec/src/inline-grid-column-carriers.test.ts 13/13; @objectstack/spec suite 584 files / 17179 tests green; @objectstack/spec typecheck green; 114/114 derived gates exit 0. Ablations, each restored with git diff HEAD empty: reference removed, 5 red; cross-reference call removed, 3 red. os validate on a probe stack: identity-only column, exit 1 STACK_CROSS_REFERENCE_INVALID; typed and bogus columns, exit 1 STACK_SCHEMA_INVALID; valid columns, exit 0.

Acceptance notes

• No check read subforms[].childObject before this change (validateCrossReferences read only form.data.object), so the child-object lookup is new here.
• The identity-only check runs in defineStack only. A view saved through the metadata door, or a subform whose child object lives in another package, gets the schema half alone (NOT MEASURED at the save door). objectui's @object-ui/types mirror is still z.any(), and the render-time warning stays the backstop there.
• field.zod.ts's scale describe still names only the declared-type refusal. PR docs(spec): field.useGrouping is live at the objectui pin, and its docblock describes the heuristic the renderer uses #20908 holds that file.

📓 Docs Drift Check

This PR changes 1 package(s): @objectstack/spec, touching 6 documentable anchor(s). ⚠️ 1 changed file(s) yielded no anchor (packages/spec/dropped-refinements.baseline.json), so the pages documenting them are NOT COVERED by this run — this is not a clean bill of health for those files.

3 hand-written doc(s) NAME something this change touched and may need an implementation-accuracy re-verification:

• content/docs/protocol/objectui/concept.mdx (via FormViewSchema (symbol, a top-level const))
• content/docs/protocol/objectui/index.mdx (via FormViewSchema (symbol, a top-level const))
• content/docs/protocol/objectui/layout-dsl.mdx (via FormViewSchema (symbol, a top-level const))

⛔ 1 release-owned page(s) also name something this change touched. These are read-only:

• content/docs/releases/v17/17-3.mdx (via FormViewSchema (symbol, a top-level const))

content/docs/releases/ is RELEASE-OWNED (AGENTS.md "Documentation Guardrails"): release
notes are written centrally at release time, and a code PR that edits them is the exact PR
that guardrail exists to stop. They are still audited — read-only. If one of them is actually
wrong, file an issue or open a dedicated docs-only PR; do not edit it here.

What this run could not see

• 1 changed file(s) yielded no anchor (packages/spec/dropped-refinements.baseline.json) — pages documenting those are invisible to this run
• 5 name(s) were too generic to anchor anything (single lowercase words)
• the SDK route bridge reached 54 of 206 client-bound route-ledger rows — the other 152 have no registrar path: tail to select them, so pages documenting THEIR client methods cannot appear above, on this or any run. Of those 152: 0 are remediable by widening that discovery convention (an in-repo file declares the path; the convention did not scan it); 55 are structural — on a ledger where NOT ONE row is declared in-repo, so no discovery change reaches them at any price; 97 are undecided (no in-repo declaration, on a ledger that has other in-repo registrars — absence and an unreadable spelling are not distinguishable here). The rows themselves: node scripts/docs-audit/affected-docs.mjs --bridge-coverage
• a page that states a rule by its inputs shares no identifier with the emitter that implements the rule, so an emitter-only diff cannot list it — not on this run and not on any run. Measured on fix(driver-sql): emit varchar(maxLength) for a text field a declared index keys on #11430: content/docs/protocol/objectql/types.mdx documents the text-family column mapping by the ObjectQL type names it maps FROM (text / textarea / html) while the diff changed createColumn; it went unlisted, and it was the page that diff falsified, in four places. No shared token exists to detect this on, so a rule your change carries has to be re-read by hand in the pages that restate it.
• a key NAME is not a key, so the hand re-read the line above prescribes can land on the wrong schema. The same spelling is authorable on one governed type and a [REMOVED] tombstone on another for each of active, aria, joins, objects, template, tools and version (censused on [finding] tools is a key on BOTH AgentSchema (tombstoned, dead) and SkillSchema (live, cloud-attested), so a name-based search attributes skill examples to the agent key — it produced a false stop-the-line alarm on PR #19059 #19093 over the liveness ledger's governed types, top-level keys); nothing in a search result distinguishes the two, so a grep hit on a LIVE example reads as evidence about the DEAD key. Measured on fix(spec): the agent.tools liveness row says dead — it claimed live on a key the schema tombstoned #19059: content/docs/ai/agents.mdx was reported as contradicting the agent.tools tombstone over its tools: example at :161, which is inside the defineSkill({ block opened at :155 — the page was already correct. Settle ownership by PARSING the value against both schemas, never by the name: that literal PASSES SkillSchema, and as an AgentSchema it FAILS at tools with the tombstone prescription. ⛔ These names are not the whole class — a key retired through a .strict() guidance map leaves no tombstone in the walked shape and none of them here (tool.category, live as AIToolDefinition.category).

Coarse fallback — 137 page(s) merely mention a changed package (the pre-#9192 predicate, kept for the deliberately-wide backstop): node scripts/docs-audit/affected-docs.mjs --json 67c1b11a20f78d6bf37efbd45d896cd22b7fb4d1 → packageMentionDocs.

Which tree this was computed on

This run read content/docs from 4b1361d239dab4945749ce809f6cfd74b0223ee0 — the merge of head feba1a99bddefae5bd1f9271848add43864aa9db into base 67c1b11a20f78d6bf37efbd45d896cd22b7fb4d1, which is what actions/checkout gives a pull_request run. Not the PR head.

A worktree cut from an older main holds a different content/docs, so re-deriving there can legitimately return a different list — that is a different tree, not a wrong row. To answer on the same tree:

# while this PR is open — GitHub drops the merge commit once it closes
git fetch origin 4b1361d239dab4945749ce809f6cfd74b0223ee0 && git checkout 4b1361d239dab4945749ce809f6cfd74b0223ee0
# afterwards, rebuild it from the two parents, which stay fetchable
git fetch origin 67c1b11a20f78d6bf37efbd45d896cd22b7fb4d1 feba1a99bddefae5bd1f9271848add43864aa9db && git checkout -B drift-repro 67c1b11a20f78d6bf37efbd45d896cd22b7fb4d1 && git merge --no-ff feba1a99bddefae5bd1f9271848add43864aa9db

node scripts/docs-audit/affected-docs.mjs --json 67c1b11a20f78d6bf37efbd45d896cd22b7fb4d1

⚠️ That checkout carried uncommitted changes, so the commit above does not fully identify what was read.

Advisory only, and a precision-first one (#9192): a page is listed because it names a
symbol, wire route or SDK method this diff touched — not because it mentions a changed
package. Each row says which anchor put it there, so a wrong row is reportable rather than
merely annoying. To re-verify, run the docs-accuracy-audit workflow scoped to these files:
node scripts/docs-audit/affected-docs.mjs 67c1b11a20f78d6bf37efbd45d896cd22b7fb4d1 → pass the list as

Local-runs: none

① Derived judgments

Inputs read: card #20901 (body; comments 5916820410 triage, 5916997003 claim, 5918594163 dev report, 5918621378 seat ruling), ruling B 5791803339 on #19629 and ruling 乙 5805782503 on #19910, PR #20927 body and file list, the net diff origin/main...feba1a99bd (merge-base def279a39b; 10 files, +573/−11), and the head's check-runs. Tree facts were read with git show / git grep on origin/main (aaad682dbc) and the head. Nothing was built, run or re-run; the dev's evidence lines are not re-measured here — the check-runs stand for them.

Accept-set and public-surface changes the diff implies

1. FormViewSchema.subforms[].columns moves from z.array(z.any()) to z.array(InlineGridColumnSchema) (packages/spec/src/ui/view.zod.ts). RIGHT. It is the same schema object, not a copy: imported from ../data/field.zod, the module whose inlineColumns already takes it (field.zod.ts:1483), and the pin packages/spec/src/inline-grid-column-carriers.test.ts asserts element identity with toBe. Every rule the column schema holds lands on the form-view carrier with its own message: an unknown key is named, field / fieldName / key are refused with the prescription naming name (the strictObject alias table), name is required, and scale on a column declaring type: 'currency' is refused with the ruling-B/乙 first sentence (INLINE_GRID_CURRENCY_SCALE_REFUSAL, field.zod.ts:866). Rulings B and 乙 therefore hold on both carriers — triage item 1 and claim item 1 as ordered. Reach: every parse of FormViewSchema — defineStack (views: z.array(ViewSchema), stack.zod.ts:370; form / formViews at view.zod.ts:4811-4813), os validate (loads through defineStack, cli/commands/compile.ts:266), the view metadata type (ViewMetadataSchema, registered in kernel/metadata-type-schemas.ts:112) and the ViewItem form arms. The card's typed-currency-with-scale column and its bogus-key column are refused at the view parse; the identity-only column still passes the schema, correctly (the schema cannot see the child field), and is judged in item 2.

2. New packages/spec/src/stack.zod.ts#collectHydratedInlineColumnErrors, called from validateCrossReferences on the PARSED stack (result.data, so every column it sees already passed the strict parse). RIGHT, and the lookup resolves correctly on both carriers:

   • inlineColumns: judged against obj.fields of the object that OWNS the relationship field. A master_detail field sits on the child object, so the column names a sibling field of the same object document — the card's own reading of site 2. Pinned at Object 'crm_invoice_line' field 'invoice' inlineColumns[1].scale.
   • subforms[].columns: judged against fieldsByObject.get(subform.childObject) for view.form and every view.formViews entry, which are the container's only form slots (view.zod.ts:4796). Pinned on both slots.
   • No second scale rule: the column is re-parsed as { ...column, type: resolved } through InlineGridColumnSchema.safeParse and every issue that parse raises is reported verbatim under a locating prefix. The only table is HYDRATED_INLINE_COLUMN_TYPE with the one row currency, and the column schema's superRefine has exactly one type-conditional rule (field.zod.ts:957), so the table is complete against the tree. Own-key lookup (hasOwnKey) keeps a column named constructor off the prototype chain. A column declaring a type, a column naming no field of the child, and a childObject the stack does not declare are skipped — all pinned as controls. Envelope STACK_CROSS_REFERENCE_INVALID / 422, pinned.
   • Reach is narrower than the schema half and the diff says so: config.objects only (not artifactObjects, which carry names and no fields), and only where defineStack runs (os validate, os build, the dev loader); the metadata save door gets the schema half alone (PR body, acceptance note 2).

3. ADR-0087 route: two step-18 D3 entries, no D2. RIGHT under ruling B. A lossless conversion for scale would be a key-dropping load-time grace window, which B refused (「⛔ no alias, ⛔ no grace window」) and which the family's sibling entries field-currency-scale-refused and inline-grid-column-currency-scale-refused already declined for the same reason; an unknown key or a mixed field / name entry is the author's judgment (the field-column-lists-canonicalized conversion leaves exactly those alone by design). No conversion touches the key, so a stored view is never stripped. Registry: gen:migration-registry output, +77/−0 against the merge-base, both hunks byte-identical to their entry sources (mechanically diffed), entry count 328 to 330, each inserted in id order beside its family. The serial constraint held: the registry hunks are the last commit (feba1a99bd), after the merge of def279a39b, which carries feat(spec)!: connector-attached sync leaves the connector — syncConfig / fieldMappings retired, mapping gains the connectorSource pull binding (#20281 stage 1) #20903 (0efbdc3421) and fix(objectql,spec)!: a groupBy on a multi-value field and a count_distinct on a JSON-stored field are refused INVALID_FIELD / 400 at the engine aggregate door, on every driver (#20808) #20911 (975b2481cd); check:generated is green on the head. One route question stays open — ③ item 6.

4. packages/spec/dropped-refinements.baseline.json hand edit: five new sites (form.subforms.element.columns.element and its formViews and union-arm positions) and the header total 612 to 617; publishedSchemasWithDroppedRefinements stays 212 because every new site sits under a schema already listed. LEGITIMATE. The ledger is hand-edited by design ("no gen: script: a generator would let a new gap be admitted by running a command instead of by a decision"), build-schemas.ts fails until the line moves with the site, and the growth is exactly the column superRefine now reachable by reference through the form-view carrier — z.toJSONSchema() cannot emit a custom check, so each new position is a real dropped site, not a weakening. No refinement was removed or loosened.

5. Generated references content/docs/references/ui/view.mdx and api/protocol.mdx: regenerated; columns renders the declared column shape instead of any[]. RIGHT; the gate is green.

6. The pin file: 13 cases (6 schema, 7 defineStack), importing ./ui/view.zod and ./stack.zod from src. The controls include { name: 'amount', type: 'number', scale: 2 } over a currency child field ACCEPTED — the existing contract (a declared type opts the column out of hydration), consistent with the schema message "scale stays valid on a number column".

Author-shown and AI-facing text, tested sentence by sentence (true unless noted)

• view.zod.ts describe and comment: true. "referenced rather than copied" — pinned. "Until this was a reference the carrier was z.array(z.any())" — origin/main view.zod.ts:4374. "defineStack's cross-reference check judges that resolved type" — true from the moment this PR lands.
• stack.zod.ts docblocks:
  • "objectui's hydrateColumns (packages/plugin-form/src/deriveMasterDetail.ts, at the .objectui-sha pin) leaves a column that declares a type alone and otherwise sets type: fieldTypeToColumnType(childField.type), whose only currency arm is the currency field type" — UNSOURCED within this review's inputs. The hydration half is sourced in-tree (the InlineGridColumnSchema docblock names the same file and says a declared type opts out); the fieldTypeToColumnType arm claim is a reading of objectui at pin db11afd4 that only the dev made, and the pin-citation gate skips a sha-less citation by design ("skipped, not excused"). If wrong, the consequence is under-reach only — a missing row means an unjudged column, never a false refusal — and the currency row itself is the card's own measured fact.
  • "Resolution is against the stack's own objects, like the view data-source check in validateCrossReferences" — OVER-BROAD. The data-source check also admits artifactObjects and REFUSES an undeclared object ("… which is not defined in objects."); this check reads config.objects only and SKIPS. The likeness is the resolution set, not the disposition; the sentence is exact only for a stack built with no artifactObjects.
  • "a new type-conditional rule on the column adds its row here" — an instruction with no pin behind it: nothing reds if InlineGridColumnSchema gains a second type-conditional rule and this table does not. ③ item 9.
• D3 entry form-view-subform-columns-closed (runtime strings): surface, replacement and acceptance criteria — true. Reason: "a mis-keyed column published clean and drew a blank grid column" — sourced (INLINE_GRID_COLUMN_HISTORY, field.zod.ts:848); ruling dates 2026-09-23 (B) and 2026-09-24 (乙) — match 5791803339 and 5805782503; "zero authored subforms in the repository … one authored inlineColumns block" — re-measured on origin/main aaad682dbc: 0 authored subforms outside tests and docs (showcase project.view.ts:184 says why), 1 inlineColumns block (examples/app-showcase/src/data/objects/invoice.object.ts:244, seven { name } entries, no scale). "the one mechanical respelling the family had (field → name, conversion field-column-lists-canonicalized) is already retired from the load path" — TRUE of the conversion (conversions/registry.ts:7656, retiredFromLoadPath: true) but OVER-BROAD in what it implies: that conversion walks object FIELDS' inlineColumns / relatedListColumns only, so migrate meta never respells a form-view subform column; on this carrier the author respells by hand, which the replacement text does say. The comment above the entry (not a runtime string): "A stored view whose column fails is refused with the column schema's own prescription, never stripped" — true at the save door (saveMetaItem, 422) and for authored source; at the stored-row rehydration seam the ADR-0087 addendum registers the row anyway under a [metadata_spec_invalid] diagnostic — diagnosed, not refused, not stripped. No runtime string carries a tracker number.
• D3 entry inline-grid-column-identity-only-currency-scale-refused: surface ("any value, scale: 0 included"; "a column declaring type: 'number', and a column over a field of any other type, keep scale") — true (column.scale !== undefined in the schema; one table row; a declared type is skipped). Replacement — the 乙 remedy, no pointer to currencyConfig.precision; "do not add type: 'number' to keep it on a currency amount" is guidance, not a refusal an author will meet: the schema and the controls ACCEPT that shape today. Reason: "the recommended form" — sourced (field.zod.ts: "The minimal — and recommended — authored entry is identity-only"); "the console ignored it" — card body (objectui PR ci(release): refresh the Version Packages PR on a schedule, not on every push #11238). The reach sentence matches the code. Acceptance criteria — true.
• Changeset .changeset/20901-inline-grid-column-carriers.md: title with !, Clause-②: yes (narrowing), exactly one adr-0087: registered marker naming both ids (both new in this diff — the gate's registered condition), the **BREAKING** banner with minor under the pre-GA level rule (ADR-0087 amendment of 2026-09-13; check-changeset-no-major refuses major), the FROM → TO table and the one-line fix. Every sentence tests true. "wherever a view is parsed against the spec: defineStack, objectstack validate, and the view metadata type's registered schema (ViewMetadataSchema)" also reaches the ViewItem form arms — under-stated, not false. "The console fills such a column's type from the child field" — card body.
• PR body: "No check read subforms[].childObject before this change" — OVER-BROAD. os doctor collects it as an object reference (packages/cli/src/commands/doctor.ts:811-812) and lint's react-page walk resolves it (packages/lint/src/validate-react-page-props.ts:784); true as "no defineStack cross-reference check read it", which is what the dev report says. "The identity-only check runs in defineStack only" — true, os validate reaching it through defineStack. "13/13", "584 files / 17179 tests", "114/114", the ablation counts and the os validate exit codes are the dev's own runs, not re-run here. Acceptance note 3 on the field.zod.ts describe — true and routed (③ item 5).
• Sibling entry already on main, NOT in the diff but falsified in scope by it: packages/spec/src/migrations/entries/semantic/18.inline-grid-column-currency-scale-refused.ts — surface "and on a column that declares no type, is untouched", acceptance "columns declaring no type, keep their scale". True of that entry's own refusal; false as an author's takeaway for an identity-only column over a currency child field from the moment this PR lands, since defineStack then refuses it. The two step-18 entries disagree on that one sentence. ③ item 5.

② Semver level

Clause-②: yes (narrowing)

'@objectstack/spec': minor, title feat(spec)!:, **BREAKING** banner, one ADR-0087 marker — matches what the diff publishes: an accept-set narrowing on a published authoring surface (subforms[].columns) plus a new defineStack refusal; no export added, removed or renamed (check:api-surface green); no other released package changes code. yes is sourced by the generated reference diff — columns moves from any[] to a declared key set, keys newly declared on a published payload; (narrowing) is the arm the gate grades as breaking; both readings owe at least minor, which is declared. major is barred pre-GA. Ruling B's own PR (#19909) declared no (narrowing) for a refusal that declared no new key; the declared key set is the difference here, so the two declarations are consistent. Check Changeset is green on the head.

③ Boundary flags

Dev report 5918594163: open_questions: [] — nothing to answer. No deviations key; the one substantive deviation is stated in its summary and judged as item 1. out_of_scope_findings: four, answered as items 2 to 5. Items 6 to 9 are this review's own.

1. Premise falsified — the dispatch assumed an existing check resolved subforms[].childObject; none did inside defineStack. ANSWERED: the dev built the resolver in validateCrossReferences, inside the dispatched surface ("the cross-reference check that resolves childObject … expected in packages/spec or packages/lint"; the dev located and named it), and field.zod.ts (held by PR docs(spec): field.useGrouping is live at the objectui pin, and its docblock describes the heuristic the renderer uses #20908) is untouched — the file list confirms. premise_still_valid: true reads as the card's finding still holding, which it does; the mechanism premise did not, and the report says so in words.
2. Third carrier ObjectMasterDetailFormPropsSchema.details: z.array(z.unknown()) (packages/spec/src/ui/component.zod.ts:4563) — VERIFIED in the tree; class c with measured reach. ESCALATED: its own card in this family. The seat ruling says it files it; not verified by this record.
3. packages/lint/src/validate-field-consumers.ts LITERAL_KEYS holds 'name' (:285), so a subform column's name never counts as a field reference and field-no-consumers calls a field the grid shows "inert" — VERIFIED in the tree; class a. ESCALATED: its own card in packages/lint. The seat ruling says it files it; not verified here.
4. objectui mirror @object-ui/types subforms[].columns: z.any() — the coordination child triage named; it follows the pin bump. ESCALATED to the objectui lane; the card body already records it.
5. field.zod.ts superRefine comment and scale describe now describe only the schema half — routed to PR docs(spec): field.useGrouping is live at the objectui pin, and its docblock describes the heuristic the renderer uses #20908's holder, correct since that file is held. ADDED by this review: the same staleness sits in 18.inline-grid-column-currency-scale-refused.ts (① last bullet), which is NOT held by docs(spec): field.useGrouping is live at the objectui pin, and its docblock describes the heuristic the renderer uses #20908 and lives beside the two entries this PR adds. Required follow-up, owner the domain:spec seat: amend that entry's surface and acceptance sentence to point at inline-grid-column-identity-only-currency-scale-refused, regenerate the registry. Before protocol step 18 ships a docs-only PR is enough; it can also ride the docs(spec): field.useGrouping is live at the objectui pin, and its docblock describes the heuristic the renderer uses #20908 round if the seat prefers one edit to the family. Not held against this head: the end state after applying both entries is right, and the runtime refusal carries the fix.
6. Route question, ESCALATED to the seat: the launch-window policy asks for a retiredFromLoadPath chain step "when lossless". The field → name respelling on the NEW carrier is lossless and has no chain step (the family's conversion walks object fields only). Mitigating: 0 authored subforms in the repository, deployed metadata NOT MEASURED, and the grid has honoured no field spelling on any carrier since objectui#3951, so no working shape breaks; the D3 replacement text tells the author to respell. The seat decides whether to widen field-column-lists-canonicalized's walk to views[].form / formViews.* subforms[].columns in a follow-up, or record why not. This record does not hold the PR for it.
7. Console Pin Gate SKIPPED by its paths filter (.objectui-sha, build-console.sh, check-console-sha.mjs untouched): the objectui build against the narrowed FormView type is NOT MEASURED on this head. Low risk — no export removed or renamed (the AGENTS.md pre-merge check is for removals), and objectui judges views through its own mirror. Noted, not held.
8. Stored views: refused at the save door; diagnosed and registered at rehydration per the ADR-0087 addendum ("reads diagnose, never drop"). Triage's "refused with guidance, never silently stripped" holds at the authoring and save seams; the seat ruling's "A stored view is refused" is that sentence in the ruling's words. No action; recorded so nobody reads the read path as a refusal.
9. The comment-only instruction "a new type-conditional rule on the column adds its row here" is unpinned. Optional hardening for the seat: a test that enumerates the column schema's type-conditional rules against HYDRATED_INLINE_COLUMN_TYPE.

• Item 4: the objectui coordination child, for the @object-ui/types subforms[].columns mirror, is filed when this PR lands.
• Items 5 and 6: one follow-up PR, Part of finding(spec): an inline grid column is judged on only one of its carriers — FormViewSchema.subforms[].columns is z.array(z.any()), and a currency column's scale reaches no refusal when its type comes from the child field #20901, taken first after this PR lands, ahead of packages/spec/src: 1,277 comment lines still cite 170 deleted tracker numbers (1,295 sites) — the staged remainder of ruling C+D on #19123, measured by PR #20226 #20234 stage 11 on the registry.
  • Item 5: 18.inline-grid-column-currency-scale-refused.ts says number columns, and columns declaring no type, keep their scale. The follow-up amends that surface and acceptance sentence so it points at the new identity-only entry, then regenerates the registry.
  • Item 6 is ruled WIDEN, not "record why not". ADR-0087's pre-GA policy says every break lands as a chain step, and a lossless one as a retiredFromLoadPath conversion, in the same release. The field → name respelling on the new carrier is lossless. So field-column-lists-canonicalized walks subforms[].columns too, on views[].form and every formViews entry, and its surface string names both. Zero authored population lowers the risk. It does not waive the chain.
• Item 9 (pin the "add its row here" table) is optional hardening. It rides the same follow-up if it stays inside stack.zod.ts's test.
• The ① text imprecisions are fixed in the files the follow-up touches. The stack.zod.ts comments and the PR body's "No check read" sentence are recorded for the next touch of each. None of them is a runtime prescription.
• Not governed. needs:contract-review comes off in a separate act after this record reads back. Then the PR goes ready and into the merge queue.
