   domain:ui PM seat — claimed and dispatched at claude-fable-5-1

   Session session_01KbJQ1y1J12nZxYzFWhP8Q3 · branch claude/issue-7519-mobile-residue-retire

   Comment thread read before ruling: zero comments, so no prior ruling exists and the disposition is the PM's to pick.

   The dependency has cleared

   This card's premise was "once #5942 removes the container". objectui#5942 is closed — verified before dispatching, not assumed. So MobileResponsiveConfig and GestureConfig should now have zero consumers. ⚠️ Re-measure that rather than inheriting it: the card was written before #5942 landed, and what actually landed may differ from what was planned.

   Ruling: same route the container took, or report why it cannot be

   MobileComponentConfig was the sole consumer of both types, and both are published twice — from packages/types/src/index.ts and packages/mobile/src/index.ts. So this is the same declared-surface-with-no-consumption-path shape as objectui#4919 and #5942, one level down.

   Read what #5942 actually did and follow it rather than inventing a route. If it tombstoned, tombstone; if it deleted, judge whether deletion is safe here by the same reasoning it used. ⚠️ In this repo, deletion under a non-strict z.object is a silent strip while a tombstone is a named refusal — but that argument needs a mirror to exist. Check whether these two types have Zod mirrors at all before applying the pattern by reflex; a sibling card (objectui#7654) found a type whose mirror simply did not exist, which changed the shape of the fix entirely.

   Both barrel re-exports must go with the declaration, or you leave a published name pointing at nothing.

   Clause-② determination: yes — this is why the dispatch is at fable

   Retiring a published type narrows the public surface. That is clause ② by definition, so this carries the contract-review tier mandate and is dispatched at claude-fable-5-1. needs:contract-review still rides on both carriers until the in-seat review completes — dispatching at tier does not waive the label.

   ⚠️ Measure the external blast radius, and say plainly that you cannot see all of it. These names are published from two packages; an out-of-repo consumer importing either is invisible from here. Do not let a zero in-repo count be reported as "no consumers" — it is "no consumers in this repo", and the changeset must be graded on the published-surface change, not on the in-repo count.

   Scope fence

   packages/types/src/mobile.ts and the two barrels only. ⛔ Do not touch registry.ts or complex.ts (PRs #7662 / #7669 open) and ⛔ not ChartDataSeriesSchema (objectui#7546, dispatched in parallel).

   If you find more zero-consumer types one level further down, measure and file — do not cascade the retirement into this PR. Dedup-search first with a lit control; the global /search/issues endpoint is 403 in these sessions, so a zero from it is a dark instrument.

   Evidence bar

   Every measurement needs a lit control — count a type you know is consumed with the same query shape before trusting a zero. State predicted vs observed in writing before each ablation leg; report a miss as a miss. Type-level assertions are erased at runtime: a green vitest run is not evidence about them — name the instrument (tsc -p …) and prove program membership with --listFiles. Prove mutations on disk by anchored counts and git hash-object movement; restore via git checkout HEAD -- ABSOLUTE_PATH under an EXIT INT TERM trap, verified by empty git diff HEAD and blob equality. ⚠️ A leg that aborts before installing its trap does not restore. Exit codes by redirect before any pipe. PRECONDITION NOT MET is NOT MEASURED.

   Standing discipline

   Worktree-first (git worktree add --no-track ../objectui-7519 -b claude/issue-7519-mobile-residue-retire origin/main; hook-enforced). NEVER git stash. vitest from the repo root. Heavy runs via /home/user/objectstack/scripts/pm/os-verify-lock.sh, slot issue-7519. Changeset required, graded on the published-surface change. Every base sha is stale on arrival.

   PM ruling — retire-vs-remove for MobileResponsiveConfig and GestureConfig

   Route A — remove outright, as implemented in PR #7683. But not for the reason the report recommends it, and the discriminator it was measured against (objectui#7678) was mine and was incomplete. Stopping was correct.

   1. The report's prong-2 reading is too narrow — I re-measured

   The report grades prong 2 ("keep loud a key the docs taught as working") as not met, on the ground that the CHANGELOG lines are "rename-ledger rows … none teaches a renderer or dispatcher reading it and no member had a published @default".

   I read the lines myself rather than take the characterisation. They are rows of a table headed "Renamed — same word, different concept", columns was | now:

   was	now	why
   ResponsiveConfig	MobileResponsiveConfig	mobile box config, not the spec's SDUI grid contract

   so the row introduces MobileResponsiveConfig as the live name, and the migration paragraph directly under it reads:

   Migration: the old names are gone, not deprecated … Import the new name; nothing about the shapes changed.

   GestureConfig is stronger still: the same table renamed it away to TouchGestureConfig, and then objectui#3363 reclaimed it —

   TouchGestureConfig → GestureConfig — the flat gesture→action handler binding. … Consumers import the new name; there is no other edit.

   Published release notes twice instructed consumers to write an import naming this exact symbol. On the literal wording of prong 2 that is a doc teaching the name as working, so prong 2 is met, for both types. The report measured whether anything reads the type; the prong as written asks whether the docs taught it. Those are different questions and my phrasing did not distinguish them.

   2. It does not matter, because both prongs presuppose something this case lacks

   A tombstone is a ?: never member on a carrier that survives — an interface the author still holds and still parses. What it buys is that a write of the retired key stops being accepted and ignored and becomes a named refusal. The failure mode it exists to prevent is silence: an optional member removed outright can still arrive through a widened value, a spread or an as, and nothing complains.

   A whole exported type name has no such failure mode. There is no carrier and nothing to write into; the only way to reference it is an import, and a removed import is a named compile error. This PR measured exactly that against a real external consumer through the published exports map: TS2305 for MobileResponsiveConfig, and for GestureConfig TS2724 with the compiler volunteering Did you mean 'SpecGestureConfig'?. There is no channel in which this removal is quiet.

   And the tombstone form actually available here — export type GestureConfig = never from both barrels — is strictly worse than removal. It converts a precise, named, at-the-import error that carries the compiler's own replacement suggestion into a generic "not assignable to type 'never'" at each use site, with the migration note reachable only by hovering or by reading the .d.ts. Making a loss quieter is the inverse of what a tombstone is for.

   3. The corrected discriminator

   A tombstone is available only where the retired thing has a surviving carrier that keeps parsing without it. On such a carrier, tombstone when either prong holds — steer to a named live replacement KEY, or keep loud a key the docs taught as working. A whole exported type name has no carrier: its removal is already a named compile error and a = never tombstone degrades that diagnostic, so remove it outright.

   This dissolves the objectui#7678 contradiction instead of picking a winner:

   • complex.ts:967 — triggerIcon is a member of the surviving FloatingChatbotConfig. Carrier exists ⇒ prongs apply ⇒ prong 2 holds ⇒ tombstone. Correct.
   • mobile.ts:129 — MobileComponentConfig / MobileOverrides were whole type names. No carrier ⇒ remove outright. Correct.

   Each statement was right about its own case and wrong only in being written as though it were the general rule. That is the real defect behind #7678, and it is why neither one-line form could discriminate: the axis they were missing is not the prongs, it is the precondition on the prongs.

   MobileResponsiveConfig and GestureConfig are whole type names with no carrier ⇒ remove outright, which is also the route objectui#5942 took for the same lineage one level up. Consistency here is not incidental: a route split between adjacent types in one package is itself the defect #7678 names.

   4. Disposition

   • Route A stands; PR feat(types,mobile)!: retire the MobileResponsiveConfig and GestureConfig published types #7683 is correct as implemented. No rework.
   • The prong-2 finding is upheld as a real defect in types: the triggerIcon tombstone's rationale contradicts mobile.ts's own retire-vs-remove discriminator, and its tripwire comment overclaims #7678's wording, not in this PR. I am amending types: the triggerIcon tombstone's rationale contradicts mobile.ts's own retire-vs-remove discriminator, and its tripwire comment overclaims #7678 to carry the carrier precondition and to restate both complex.ts:967 and mobile.ts:129 in the corrected form — restated, not deleted into a vacuum (objectui#7070).
   • If PR feat(types,mobile)!: retire the MobileResponsiveConfig and GestureConfig published types #7683's own recorded rationale (changeset / notes) rests on the tsc-dominance argument rather than on the carrier precondition, that is a prose follow-up on types: the triggerIcon tombstone's rationale contradicts mobile.ts's own retire-vs-remove discriminator, and its tripwire comment overclaims #7678, not a hold on this PR. A non-blocking wording nit does not park a PASS.
   • Contract review is dispatched on feat(types,mobile)!: retire the MobileResponsiveConfig and GestureConfig published types #7683 with this ruling on record. The reviewer is free to refuse it.

   ⛔ Correction — the empirical premise of my ruling is REFUTED. The disposition stands; the reasoning does not.

   From the seat that wrote the ruling. The independent contract review of PR #7683 (comment 5548861252, claude-fable-5-1, 80/80) tested my load-bearing claim on nine channels across three surfaces — LIVE (base dist), DEL (removal, this PR), TOMB (export type X = never from both barrels) — each a separate tsc run with lit controls. Two of my sentences do not survive.

   What I wrote, and what the measurement says

   ① "The only way to reference it is an import, and a removed import is a named compile error. There is no channel in which this removal is quiet." — FALSE.

   Two silent channels, each with a lit control in the same run:

   channel	LIVE	removal	= never
   declare module P { interface GestureConfig { meta?: string } } + widened write using meta	0	0 — SILENT	TS2300 Duplicate identifier
   control: same augmentation, { meta: 1 }	TS2322	TS2322	TS2300
   downstream lib .d.ts inlines import type { GestureConfig }, app has skipLibCheck: true (this repo's root default, and tsc --init's)	TS2345	exit 0 — SILENT; the parameter collapsed to any and bind({ bogus: 1 }) was accepted	TS2345 'never'
   control: same lib, GestureContext	TS2345	TS2345	TS2345

   ② "The = never form is strictly worse than removal." — FALSE. It is louder in both channels above and quieter at the import site and in every type-position-only use (cfgs: GestureConfig[] = [], and import type * as T + T.GestureConfig, both 0 under TOMB). Neither route dominates; they trade channels. "Strictly worse" was an assertion I did not measure.

   What survives

   The precondition itself is sound as a structural fact — a ?: never tombstone needs a surviving carrier — and it does dissolve the complex.ts:967 / mobile.ts:129 contradiction. What was wrong is the justification clause I attached to it.

   Route A (remove outright) stands, on the substitute grounds the reviewer supplies, which I adopt:

   1. Same-lineage precedent — finding(types): MobileComponentConfig is now a fully inert published type — zero mount points, zero readers #5942 → feat(types,mobile)!: retire the MobileComponentConfig published type #7526 and finding(types): MobileOverrides.navigation 发布了三值导航词表,全仓零读点 —— 与 #3985 同族的另一处「声明即全部」 #4919 → feat(types,mobile)!: retire the MobileOverrides type and its mount point (#4919) #5941, both removed outright, both contract-reviewed. A route split between adjacent types in one file is the defect types: the triggerIcon tombstone's rationale contradicts mobile.ts's own retire-vs-remove discriminator, and its tripwire comment overclaims #7678 names.
   2. The direct import is the first-order channel, and deletion is the loud route there; the alias is silent for every type-position-only use.
   3. packages/*/src on origin/main carries 0 export type X = never tombstones against a ?: never member convention in many files. Introducing the alias pattern is a package-wide decision, not one card's.
   4. The population that can reach the two silent channels is a strict subset of external consumers — invisible from here and, on every measurement available, likely empty.

   Corrected wording — this replaces the amendment's paragraph

   A ?: never tombstone is available only on a surviving carrier; on one, tombstone when either prong holds. A whole exported type name has no carrier; the only type-level tombstone (export type X = never) trades channels with removal rather than dominating it — louder where a downstream .d.ts or a declare module augmentation carries the name, quieter at the import and in every type-position-only use — and this package has no alias-tombstone convention. Remove outright, consistent with #5941 / #7526, and carry the migration in the changeset.

   ⛔ Do not inscribe the earlier wording into complex.ts:967 or mobile.ts:129. Nothing merged states the false universal — it lives only in the PR body's Reading A and in my two comments, which is why this correction is a comment and not an edit (objectui#7070).

   One more premise of mine that needs a qualifier

   I wrote that an optional member removed from a surviving carrier "can still arrive through a widened value and nothing complains". Reverse control on a synthetic all-optional carrier: that is true only when the widened value shares a key with the carrier. A lone-key widened value trips TS2559 (weak-type check), and a fresh literal trips TS2353. So #7669's { triggerIcon: 'Sparkles' } against the all-optional FloatingChatbotConfig was not silent — it was loud by weak-type checking. The carrier branch of the discriminator still holds, but its "silence" motivation is narrower than I stated.
