finding(types,plugin-kanban): ColumnWidthConfig / ColumnWidthConfigSchema are published with zero readers and no schema key that references them (objectui#8522 removed the last reader)

Filing-gate category: ③ a trap (class c): a published authoring type with nothing behind it. An author, or an AI, can build a ColumnWidthConfig and nothing will ever read it. Reader: triage first (route and grade), then the seat that claims it.

Filed by the domain:ui seat #2 (session_014mXUNuFomfj24w7s1pZzhN) from the objectui#8522 dev report and contract review (PR objectui#10549, which retired useColumnWidths). Recorded on ACCEPT 5829536633: "the ruling did not reach the type". ⛔ Not graded here.

Fact (read by the seat on `origin/main` at `90dbd1d31`)

git grep ColumnWidthConfig over the tracked tree, excluding markdown, finds only declarations, re-exports and ledgers:

packages/types/src/complex.ts:~274: export interface ColumnWidthConfig { defaultWidth?; minWidth?; maxWidth?; overrides? }. Its neighbouring docblock (~:249–252) already says "The one plugin-kanban reader of {@link ColumnWidthConfig} was removed by objectui#8522, whose ruling did not reach the type itself";
packages/types/src/zod/complex.zod.ts:~155: ColumnWidthConfigSchema, the mirror;
re-exports at packages/types/src/index.ts:~342, packages/types/src/zod/index.zod.ts:~271 and packages/plugin-kanban/src/index.tsx:~197 (via ./types);
ledgers: zod-mirror-parity.test.ts and one-authority-per-exported-name-6273.test.ts.

No schema key references it. The kanban arm's columnWidths key was retired by objectui#8802 (complex.zod.ts:~91), so no document can carry one, and no component reads one.

Direction (for triage, not a ruling)

This is the ADR-0049 enforce-or-remove question on a type with no key and no reader. Startup-stage policy defaults to retiring immediately.
Removing a published export means Clause-②: yes, and a minor changeset for @object-ui/types and @object-ui/plugin-kanban.
⚠️ complex.zod.ts is a hot file held by another seat's work (objectui#9306 / finding(types): the filter-builder mirror's value is z.any(), so objectui check passes a between with a scalar, an in with a non-array, or an icontains with a non-string that the spec's ViewFilterRuleSchema refuses #10478): serial.

Dedupe

REST page walk over the 1000 most recently updated objectui items (oldest updated_at 2026-09-18T15:37Z): ColumnWidthConfig ⇒ 3 hits. They are the seat post, objectui#8932 (KanbanEnhanced.tsx, a different file retirement that names the type in passing) and PR objectui#10549 (the origin). None is this card.

Dedupe words: ColumnWidthConfig zero readers · ColumnWidthConfigSchema orphan export · kanban column width config retire type

Triage: first grade — `bug` · `priority:p3` · `domain:spec` · `area:records` · `pm:queue` (`finding` removed — graded)

Triage: lands in packages/types (ColumnWidthConfig in complex.ts, ColumnWidthConfigSchema in zod/complex.zod.ts, and their re-exports) — objectui's contract face ⇒ domain:spec; rationale: a published authoring type with no key that references it and no reader since objectui#8522. The direction is written: ADR-0049 enforce-or-remove, and the stage posture retires a zero-pull declaration immediately ⇒ retire; p3.

Execution note: remove the type, the mirror and the re-exports (plugin-kanban included), update the two ledgers, minor changesets for @object-ui/types and @object-ui/plugin-kanban, Clause-②: yes.

Claim: PM loop round 1 — objectui#10582: retire ColumnWidthConfig / ColumnWidthConfigSchema (no key references them, no reader)
Session: session_014fWVhLzhxR8qrFsJ5o8TYW
Account: os-tesla
Branch: claude/issue-10582-retire-column-width-config
Worktree: objectui-issue-10582
Domain: domain:spec
Seat: domain:spec#1
File surface: packages/types/src/complex.ts (the ColumnWidthConfig interface and the kanban retirement docblock that names it), packages/types/src/zod/complex.zod.ts (ColumnWidthConfigSchema), the re-exports in packages/types/src/index.ts and packages/types/src/zod/index.zod.ts, packages/plugin-kanban/src/types.ts and packages/plugin-kanban/src/index.tsx (re-exports), the ledger rows in packages/types/src/__tests__/zod-mirror-parity.test.ts and one-authority-per-exported-name-6273.test.ts, one pin, and one .changeset/10582-…md (minor for @object-ui/types and @object-ui/plugin-kanban). Stop on breach; explain in the report.
Container & model: S, mode:subagent, model: opus (TIER_DEFAULT, scripts/pm/dispatch-gates.mjs:12534 on objectstack 16c5a33; --tier refuses objectui paths, so the tier follows the rule for a retirement that removes a published export)
Clause-②: yes
Thread-read: 5831964491
Serial constraints cleared: re-measured on objectui origin/main f9c06ef6a. The card's hot-file warning named objectui#9306 and objectui#10478: objectui#10478 is closed, and objectui#9306 is in needs-user-decision with no assignee and no PR, so it holds no edit on complex.zod.ts. None of the 7 open non-release PRs touches complex.ts, complex.zod.ts, index.zod.ts or plugin-kanban. PR objectui#10710 edits packages/types/src/index.ts at the data-display export block (@@ -252), and this card removes one name at about :343. They are separate hunks, and whichever lands second merges main. This round's objectui#10608 may also delete rows from zod-mirror-parity.test.ts. That is the shared ledger: each PR deletes its own rows, and the second to land merges main.

Clause-②: yes follows triage's execution note. A pure retirement narrows, so it would read no under the lane rule, but yes is never wrong and the .changeset prose owes an at-tier review regardless.

The complex.ts kanban docblock no longer says the type survives. Added a tree-scoped absence pin, column-width-config-retired-10582.test.ts, and one changeset (minor for both packages, breaking semantics and migration stated). Premise re-measured on origin/main 5c61e52: zero readers, producers or teaching docs in packages/apps/examples/content/skills, each with a lit control, so the stop condition did not fire. H2: the one-authority ledger has no row, only a historical comment, and it is not edited. H4 sharpened from the npm 17.6.0 tarballs: plugin-kanban@17.6.0 exports the type; types@17.6.0 exports neither name, because the pair entered @object-ui/types in this unreleased window (objectui#7664). H5: this follows the objectui#7068 ActionCallback precedent (delete the standalone pair and pin its absence); no tombstone-export convention exists.

Checklist, read on GitHub, not off the report

The PR is a draft against main. Its first line is Fixes #10582, it has a line-start Clause-②: yes, and no other closing keyword appears in the body.
9 files (+191 −38), all inside claim 5851641050. The one-authority ledger named in the claim holds no row, so that file is untouched.
The changeset is minor for both packages, states the breaking semantics, and has a Migration section.
check-governed-queue-guard --test over the 9 paths: NOT GOVERNED.
Contract review: the at-tier record 5851902469 on the PR at this head says PASS. It verified the 17.6.0 tarball claims against the npm registry, and it judged the pin able to fail (6 tests, a lit control in each; the three ablations are coherent with them).
CI at this head: all 6 required contexts are green (Lint, Type Check, Build & E2E, Build Docs, Changeset Declaration, Test with all 8 shards). 3 skips are expected (dependabot and the two coverage jobs).

The one red, and the reviewer's flag (d) on it. Inert vi.mock Specifier Check fails with the same signature on the base 5c61e5241. The anchor is objectui#10731 (PR comment 5851845225). The reviewer read the workflow header, which calls it a required context. That header is stale:

The main ruleset (GET /repos/objectstack-ai/objectui/rules/branches/main) requires exactly Lint, Type Check, Build & E2E, Build Docs, Changeset Declaration and Test.
Classic branch protection reads enforcement_level: off with no contexts.

So the red is a same-signature red on the merge base and does not count against landing.

Acceptance notes (noted, not filed)

(b) The pending 8522-retire-use-column-widths.md still says the type 「stays exported」. This PR's changeset names that entry and supersedes it in the same release section, so the pair reads consistently. A dated in-body note on the 8522 entry (the objectui#7742 precedent) would be tidier. Carrier: the release editor.
(e) Three texts attribute the columnWidths retirement to objectui#8802 alone, although objectui#7742 tombstoned it first. Non-blocking.
(f) The pin's tree walk skips .d.ts files. Non-blocking: an ambient re-declaration there cannot restore a published export.
PR assignee: not set. The dev's label-write --assign os-tesla was refused by the session's auto-mode classifier. The seat does not repeat a refused write for a subagent; the refusal is reported to the maintainer.

Landing: pr_ready + automerge_enable through the relay, then followed to MERGED.
