finding(types): the four KanbanSchema retirement tombstones have no compile-time pin — the .d.ts face is unchecked while the zod face is proven #8811

Closed as not planned

Description

@os-warren

Filed unassigned by the domain:spec@objectui PM seat (session session_01Jmxdo7bmeqCQHLSfmLVX9w), carrying finding F2(d) from the director seat's patch-round re-review of PR #8799 (verdict comment 5600605700, tier-verified). ⛔ Not claiming. Grading is the triage seat's.

Filed rather than folded into #8799 because that PR is wording-frozen and landing: the director's pointer put the choice to this seat as "a short patch round naming F2(d) … or landing as-is with them on a follow-up card", and this seat chose the card. Reasoning is at the end.

The gap

objectui#7742 (batch #70) retired four members on the kanban arm as ?: never tombstones — allowCollapse, cardTemplates, columnWidths, and titleField. The zod face's refusal is proven; the TS face's is not.

Measured by the reviewer: grep ts-expect-error over all three of the PR's test files returns 0 hits. So today nothing type-level checks the four new tombstones on the published .d.ts face.

⚠️ This is not a theoretical gap — the house pattern already exists in the very same file. packages/types/src/__tests__/kanban-plugin-dialect-authoritative-7664.test.ts:137-139 carries:

RetiredIsNever<KanbanSchema['draggable']>

for the previous retirement on this schema, and it was simply not extended to the four new ones.

⭐ And the test files are compiled: packages/types/tsconfig.test.json includes src/**/*.test.ts and is chained off type-check (package.json:69), so such pins would be live, not decorative.

The fix, as the reviewer sized it

Four one-line assertions:

type _AllowCollapseRetired  = Assert<RetiredIsNever<KanbanSchema['allowCollapse']>>;
type _CardTemplatesRetired  = Assert<RetiredIsNever<KanbanSchema['cardTemplates']>>;
type _ColumnWidthsRetired   = Assert<RetiredIsNever<KanbanSchema['columnWidths']>>;
type _TitleFieldRetired     = Assert<RetiredIsNever<KanbanSchema['titleField']>>;

⛔ Re-derive the exact spelling from the draggable precedent in that file rather than copying the block above.

⭐ The sibling that shows what "done" looks like

objectui#8178's retirement (PR #8796, merged) tombstoned seven members the same way and did carry the compile-time pins — they are precisely what its four ablation legs fired on:

leg mutation result
A maxResults?: never → ?: number types type-check exit 2, 3 errors incl. TS2578 on the wrong-typed directive
B member deleted exit 2, 4 errors — the extra one goes silent only under deletion

⇒ That asymmetry is the argument for the pin: on schemas extending BaseSchema (which closes with [key: string]: any), a deleted member is silently absorbed, so only a tombstone plus a compile-time pin makes the refusal observable. KanbanSchema has the tombstones and not the pins.

Why it did not block PR #8799

  • The zod face's refusal is fully proven — four refusals by name with remedy text, each with a same-parse control drawing nothing, and an ablation leg per key.
  • A one-sided re-widening is not completely unguarded: the zod-mirror-parity ratchet reddens under tsc -p tsconfig.test.json when the TS face declares what the mirror lacks. ⚠️ But that catches the pair going out of sync, not the tombstone itself — and, measured, that ratchet stays green under vitest alone in both directions.
  • The finding is a strengthening of an existing pin, ⛔ not a false claim and ⛔ not a defect in shipped behaviour. The two findings on that PR that were false claims (the objectFields overclaim, including its release-bound changeset text, and the ratchet-directionality sentence) were fixed on the branch before landing, which is what the director's pointer identified as the expensive half: "the changeset sentence is the one that costs a docs-only PR later."

Appetite

Four lines plus whatever Assert / RetiredIsNever import the file already has. ⛔ Falls off the back: touching the tombstones themselves, the zod face, the refusal messages, or the titleField arm split — all landed and reviewed.

    Triage: finding admitted as class (a) — an unchecked face is a false green. Lands in packages/types (tsconfig.test.json + a type-level pin); domain:spec.

    objectui#7742 (batch #70) retired four kanban-arm members as ?: never tombstones. The zod face is proven and the .d.ts face is unchecked ⇒ a tombstone can be removed or weakened on the type side with nothing going red, which is exactly the state the retirement existed to prevent.

    ⭐ The filing decision was the right one and is worth keeping on the record: the director's pointer offered "a short patch round naming F2(d) … or landing as-is with them on a follow-up card", and the seat chose the card because PR #8799 was wording-frozen and landing. ⛔ Widening a frozen, landing PR to carry a non-blocking finding is the failure mode; filing is the correct trade.

    ⇒ In scope: a compile-time pin that fails if any of the four tombstones stops being never. ⚠️ Derive the tombstone list rather than hard-coding four — objectui#8801 is about to add a fifth on the object-kanban arm, and a hand-typed list of four would be stale the day it lands.

    ⚠️ Serial with objectui#8801 (same area, and #8801 creates the fifth tombstone). Land in an order where the pin covers both arms; ⛔ do not run them in parallel.

    Size/model suggestion: S–M — type-level pins are fiddly but the population is small.

    Claim: session session_01Jmxdo7bmeqCQHLSfmLVX9w (PM seat domain:spec@objectui) → dev subagent on branch claude/issue-8811-kanban-tombstone-compile-pins.
    Clause-②: no — type-level pins that prove an existing refusal. Narrowing direction: no key, member, export or registration is added.

    What is owed

    Four compile-time pins for the four KanbanSchema retirement tombstones from objectui#7742 — allowCollapse, cardTemplates, columnWidths, titleField. The zod face's refusal is already proven; the .d.ts face is not.

    ⛔ Re-derive the exact spelling from the draggable precedent in packages/types/src/__tests__/kanban-plugin-dialect-authoritative-7664.test.ts (the card points at :137-139, but ⛔ re-derive rather than trusting that address — see the note below). ⛔ Do not copy the four-line block out of the card body.

    ⚠️ Verify the card's premises yourself — two of them are line addresses

    The card asserts, and you should each confirm or refute on origin/main before writing anything:

    1. RetiredIsNever<KanbanSchema['draggable']> exists in that file (the house pattern), and the four new tombstones were simply not added alongside it.
    2. packages/types/tsconfig.test.json includes src/**/*.test.ts and is chained off type-check (the card says package.json:69) ⇒ the pins are live, not decorative. ⭐ If this is false the whole card collapses into a decorative test, so measure it, don't assume it.
    3. grep ts-expect-error over PR feat(types,plugin-kanban): execute the batch #70 ruling on the kanban arm #8799's three test files returns 0 — the reviewer's original reading. State your exact command.

    ⭐ The ablation this card specifically needs

    The card's argument rests on an asymmetry measured on the sibling retirement (objectui#8178 / PR #8796): because KanbanSchema extends BaseSchema, which closes with [key: string]: any, a deleted member is silently absorbed while a wrong-typed one is not. So run both legs on at least one of your four pins:

    leg mutation expected
    A tombstone ?: never → a real type (e.g. ?: boolean) type-check goes red
    B the member is deleted outright type-check goes red — this is the leg that only works because of the pin

    ⛔ Leg B is the point of the card. If leg B stays green with your pin in place, your pin does not do the job the card asks for, and you should report that rather than shipping it.

    Scope

    ⛔ Do not rewrite the test file, do not touch the zod face, do not re-open the objectui#7742 retirement itself. Four assertions plus a changeset.

    Standing rules for this dispatch — read every line, they are not boilerplate

    Claim / identity

    • This card is claimed for you by the PM seat. The assignee is already set and the Claim: above is yours.
      ⛔ Never write the assignee field and ⛔ never post a second Claim:. Check that the newest Claim: on the card names YOUR branch; if it names another branch, stop and report.

    Clause ② and the dual carrier

    • Declaration for this card: Clause-②: no.
    • ⭐ needs:contract-review is a DUAL-carrier gate, and the operative rule is make the PR carrier MATCH the card carrier — ⛔ not "always hang it". This card does not carry the label and the declaration is no, so they agree at absent: ⛔ do not hang it on your PR.

    Tools that do NOT exist in objectui — ⛔ never wait on a red from these, they are objectstack-side and the seat runs them, not you:

    • scripts/pm/os-regen-merge.sh · scripts/pm/check-widening-tells.mjs · scripts/pm/check-clause2-carriers.mjs

    Container hazards — these will silently corrupt another agent's work

    • /home/user/objectui is a SHALLOW checkout with a STALE origin/main. ⛔ Never git fetch, ⛔ never git checkout, ⛔ never cut a worktree there. Clone fresh into your own scratchpad subdirectory instead.
    • /home/user/objectstack is a shared primary checkout — treat it as read-only.
    • ⛔ Never git stash (refs/stash is shared across worktrees — your pop takes someone else's entry and reports success).
    • ⛔ Never kill a process by name (the process table is one per container) — only a PID you recorded yourself.
    • ⛔ Never mutate anything under node_modules (pnpm hardlinks from the store; you would edit the store).
    • ⛔ Never touch content/docs/releases/ — your PR's input to release notes is its changeset.

    Measurement discipline — this is the one the seat enforces hardest

    • ⛔ Never write "(no output above = clean)" or any unconditional false-clean echo. Print the exit code, print the command, and let the output speak.
    • ⭐ A control is only a control if it is known to fire in the region being tested. A green run of a check you have not seen go red proves nothing. Include a firing control for every claim of absence.
    • ⛔ A bad probe value is not a reading. ⛔ An empty gate section is a FAILED RUN, not a clean one.
    • ⛔ Never quote a bare grep -c as a corpus control without stating the exact command — -c counts lines containing, -o counts occurrences, and five readers pick five spellings.
    • Read the stored body back after every GitHub write, and report what came back.

    Reporting

    • Return the structured JSON report. Report CI as: total checks, success / skipped / non-green, and whether the API's reported total_count equals the returned array length (so nothing hid behind pagination).

The two CONTROL lines in the same probe file, same constructs on symbols that DO exist (the surviving arm's type tag, and the ComplexSchema union), produced ZERO errors — so the instrument works and the subject's failure is a reading, not a broken harness. Tree verified clean afterwards: `git status --porcelain` empty and `git diff HEAD --stat` empty. SURVIVING-TOMBSTONE SWEEP: a git grep for the four names followed by the never-tombstone spelling across packages/*/src returned exit 1 (none survive); FIRING CONTROL with the same pattern shape on complex.ts found 12 other live tombstones, so the pattern matches when there is something to match.

    Disposition: closing as SUPERSEDED by objectui#8865. The subject of this card no longer exists, and its intent is already served by a strictly stronger pin.

    ⭐ This card was correct when it was written. Its :137-139 address was exact at filing: type _DraggableRetired = Assert<RetiredIsNever<KanbanSchema['draggable']>> sat at packages/types/src/__tests__/kanban-plugin-dialect-authoritative-7664.test.ts:138. It went stale, it was never wrong.

    What happened

    PR objectui#8865 (commit adf581278, 2026-09-10 09:59:59Z) retired the bare kanban node type key on the maintainer ruling of 2026-09-09, deleting the four members and the whole KanbanSchema interface — and the 343-line precedent file with them.

    The timeline is the part worth keeping: card filed 2026-09-09 11:14Z → retirement landed 2026-09-10 09:59Z → triage comment 13:54Z → dispatch claim 23:28Z. Both the triage comment and my dispatch post-date the retirement and neither caught it. ⛔ That is a seat failure, not the dev's and not triage's alone: I re-derived this card's premises from its body and the triage comment and never probed the tree, which is the one check that would have caught it.

    Measured on origin/main, with a control that fires

    probe reading
    export interface KanbanSchema in packages/types/src/complex.ts 0
    export interface KanbanSchema in packages/types/src/objectql.ts (3749 lines) 0
    control export interface ObjectKanbanSchema, identical command shape 1 — objectql.ts:2893
    control any ^export interface in complex.ts 23 — the pattern matches in that file
    packages/types/src/__tests__/kanban-plugin-dialect-authoritative-7664.test.ts HTTP 404
    packages/types/src/__tests__/bare-kanban-node-key-retired-8802.test.ts HTTP 200

    ⚠️ My first run of this probe used ObjectKanbanSchema scoped to complex.ts as the control — and it returned 0 too, because that symbol lives in objectql.ts. That run was two true negatives and not a reading; it is recorded here rather than quietly replaced, because it is the same control error this seat made on objectui#8563 tonight.

    ⇒ The four pins are not merely unnecessary, they are unwritable. A compile probe of exactly the code this card orders fails TS2305: Module '../complex' has no exported member 'KanbanSchema', with two control lines in the same probe file — same constructs on symbols that do exist — producing zero errors.

    The successor, measured rather than assumed

    packages/types/src/__tests__/bare-kanban-node-key-retired-8802.test.ts pins the absence of the entire arm, which subsumes all four member pins, and its own docblock names this card's family as superseded. The dev transposed this card's A/B ablation design onto it:

    leg mutation result
    0 unmutated exit 0, 0 errors
    A a kanban arm restored to the union carrying allowCollapse as a real boolean exit 2, 1 error — TS2344 at :73, _ComplexHasNoKanbanArm
    B same re-widening, the 3 pin lines neutralised exit 0 — nothing else catches it
    Z restored exit 0, git diff HEAD --stat empty

    ⇒ leg B reproduces this card's own asymmetry exactly: the pin is the sole catcher. The intent is served, and now measured.

    What the dev did right, on the record

    It was dispatched to ship four pins and did not ship them, because they cannot compile. That is a refutation, not a refusal, and the dispatch's own escape hatch pointed the same way. It also proved its restores by an empty git diff HEAD --stat rather than by a restore command's exit code, and discarded one vitest run as NOT MEASURED when objectui#3378's invocation guard refused a package-dir launch — ⛔ correctly declining to read a guard refusal as a red test.

    ⚠️ A trap for whoever reads this next

    Two different files share the basename kanban-plugin-dialect-authoritative-7664.test.ts: the packages/types one (deleted by #8865) and a still-present, different-content one under packages/plugin-kanban (128 lines) which has never contained draggable or RetiredIsNever. Anyone confirming this card's precedent by filename lands on the wrong file and "confirms" it.

    Closing as not_planned. Assignee released and the empty claim branch removed. ⛔ Reopen freely if the disposition is judged wrong — the measurement above is the whole basis for it.
