…uces — retire the orchestrator, declare PluginStartupResult once (objectstack-ai#16059) (objectstack-ai#18303)

Fixes objectstack-ai#16059

Executes the maintainer ruling (director seat, decision batch objectstack-ai#60,
2026-09-06, maintainer reply 「同意」): the spec keeps a startup-result
contract and it describes what the kernel actually produces. The
never-landed orchestrator is retired under ADR-0049 enforce-or-remove;
the one shape that is real is re-declared against what
`@objectstack/core` ships and core now imports it instead of declaring a
twin.

## What is retired

`IStartupOrchestrator` (`orchestrateStartup` / `rollback` /
`checkHealth` / `startWithTimeout`) plus the three schemas it tied
together — 3 emitted defs, 8 exported names across `./kernel` and
`./contracts` (11 api-surface rows).

| retired | why |
|:--|:--|
| `IStartupOrchestrator` | nothing in any repository implements it or
calls it |
| `StartupOptionsSchema` / `StartupOptions` / `StartupOptionsParsed` |
only ever the `options` argument of `orchestrateStartup`; the kernel
reads `PluginMetadata.startupTimeout` and
`KernelConfig.rollbackOnFailure` |
| `HealthStatusSchema` / `HealthStatus` | the return vocabulary of
`checkHealth` and the value of `PluginStartupResult.health` — no probe
system has ever existed behind either |
| `StartupOrchestrationResultSchema` / `StartupOrchestrationResult` |
the aggregate `orchestrateStartup` returned; no implementation, so no
aggregate was ever built |

Route 3 of the `spec-property-retirement` playbook: no authored document
carried any of the three defs, so there is no seam for a D2 conversion
and no author to hand a tombstone to. `RETIRED_DEFS_BY_MAJOR[18]` plus
the D3 semantic entry `startup-orchestrator-retired` are the
declaration, and the three `json-schema.manifest/kernel.json` keys with
their 16 `authorable-surface/kernel.json` lines are deleted deliberately
in this change. The build printed all three proofs:

```
ℹ️  3 schema(s) left the published set since 827cacb, each declared (objectstack-ai#4725):
     - json-schema/kernel/HealthStatus.json — RETIRED_DEFS_BY_MAJOR, major 18.
     - json-schema/kernel/StartupOptions.json — RETIRED_DEFS_BY_MAJOR, major 18.
     - json-schema/kernel/StartupOrchestrationResult.json — RETIRED_DEFS_BY_MAJOR, major 18.

ℹ️  3 baseline deletion(s) since 827cacb carry their own proof (objectstack-ai#4650):
     - kernel/HealthStatus:* (5 line(s)) — def no longer emitted by this build; …
     - kernel/StartupOptions:* (6 line(s)) — …
     - kernel/StartupOrchestrationResult:* (5 line(s)) — …
```

## What survives, re-declared

`PluginStartupResultSchema` / `PluginStartupResult` on both entries,
rewritten to the shape `ObjectKernel.startPluginWithTimeout()` has
always returned: `pluginName`, `success`, optional `durationMs`,
`timedOut`, and `error` as the serializable projection.
`packages/core/src/plugin-loader.ts` no longer declares an interface —
it re-exports the spec type, so the two cannot drift again.

Three keys of the surviving def take the tombstone route rather than a
bare deletion, registered in `RETIRED_KEYS_BY_MAJOR[18]`, because this
def keeps emitting and its type is now imported by `@objectstack/core` —
the `tsc` channel makes the prescription receivable even though nothing
parses the schema:

- `plugin` (a nested plugin object the kernel never built) — write
`pluginName`
- `health` (a `HealthStatus` nothing ever filled) — delete it
- `startTime` — see below

## The one member the ruling left open, and what decided it

The ruling did not settle whether core's deprecated `startTime` is
mirrored or tombstoned, and neither does the playbook: `startTime` was
never on the spec surface, so "retirement" was not its frame. **A repo
gate decided it.** Mirroring it reds `check:duration-unit-keys`
(maintainer ruling B on objectstack-ai#14478, no baseline, no allowlist):

```
[unit-in-prose-not-in-name] packages/spec/src/kernel/startup-orchestrator.zod.ts:136 `startTime`
  — describe names ms but the key name carries no unit.
```

Neither of that rule's two schema-declared exemptions fits: it is not an
`EpochMs` instant (it holds an elapsed duration, which is exactly the
confusion the rule separates) and it mirrors no external standard. The
remaining options were to rename it to `startTimeMs` — minting a
spelling nothing has ever produced, for a member core's own TSDoc calls
"slated for removal" — or to end the ADR-0087 L1 window here. This PR
ends it: the spec tombstones `startTime`, and
`ObjectKernel.startPluginWithTimeout()` stops setting it.

⚠️ **This is the only observable behaviour change in the diff** and the
only judgement call in it. Everything else removes surfaces nothing
read. If the maintainer wants the alias to live one release longer, the
cheap reversal is a `startTimeMs` rename in both packages; say so and it
is a one-commit follow-up.

## Evidence

**Consumers, re-measured on this card** (the ruling's assertion was
written 2026-09-06; the prerequisite was to re-verify it):

- objectstack at `827cacbf4b`: zero files outside `packages/spec/src`
name `StartupOptionsSchema`, `HealthStatusSchema` or
`StartupOrchestrationResultSchema`. `IStartupOrchestrator` and
`orchestrateStartup` hit 3 and 5 files — every one a released
`CHANGELOG.md` or a generated artifact (`api-surface/contracts.json`,
`export-origins/contracts.json`). Same-corpus controls on the same query
lit up: `defineStack` 347 files, `ManifestSchema` 62,
`PluginStartupResult` 15.
- objectui at the pinned `.objectui-sha` `53ded82bf7`: all six symbols
zero, controls `defineStack` 27 files and `ManifestSchema` 6.
- `cloud` is **NOT MEASURED** — not attached to this session, so no
reading exists for it.

**Reverse verification** (this is a cross-package type change, so the
point is proving core reads the rebuilt `.d.ts` rather than a cache).
From the committed state, `health: { healthy: true, checkedAt: 1 }` was
inserted into the success-path literal in `packages/core/src/kernel.ts`,
proven on disk by occurrence count and by `git hash-object` differing
from the HEAD blob:

```
--- marker occurrences BEFORE: 0 / AFTER MUTATION: 1 ---
MUTATED LEG EXIT=1
src/kernel.ts(795,17): error TS2322: Type '{ healthy: true; checkedAt: number; }' is not assignable to type 'undefined'.
--- restored blob 55b3458… == HEAD blob 55b3458… ---
RESTORED LEG EXIT=0
```

The tombstone's `never` crossed the package boundary and the restore
reproduced the HEAD blob byte for byte (`git diff HEAD` empty).

**Same-major bookkeeping.** The `timeout` / `timestamp` /
`totalDuration` rename registrations that objectstack-ai#15678 and objectstack-ai#15676 landed in
this same unreleased major 18 are KEPT, not absorbed. The playbook's
absorption clause is motivated by the conversion table's
fixture-disjointness contract, and those three entries record "No D2
conversion" themselves, so that mechanism does not exist here. The
tree's own answer agrees: 14 `RETIRED_KEYS_BY_MAJOR[18]` entries already
name keys whose def is retired in the same major 18 (the objectstack-ai#15513
incident-response / training / change-management family). Gate (b2)
states this steady state explicitly — "an entry naming a key the build
no longer emits at all is NOT an error".

## Acceptance notes

- The generated page keeps the frontmatter `title: Startup Orchestrator`
/ `description: Startup Orchestrator protocol schemas`. Those two
strings are derived from the module FILENAME by `build-docs.ts`; the
page BODY is rewritten and now describes the result contract. Renaming
`startup-orchestrator.zod.ts` would move the docs route, the
`export-origins` paths and the pin file's module slot, and the ruling
names the file to edit rather than to move — so it is noted here, not
done.
- `content/docs/references/index.mdx` moves 1525 → 1522 schemas and the
Kernel row 162 → 159 — the whole-def-removal reading the playbook's
ratchet-visibility table predicts, and the counter-evidence to a
zero-delta run.
- `packages/spec/src/type-alias-convention.pin.test.ts` drops `Iso467` /
`Iso469` with their schemas (785 → 783 pins); `Iso468` stays, still
isomorphic — every new member is `.optional()` with no default and no
transform.

…e the 27 signature hashes (objectstack-ai#18971)

Fixes objectstack-ai#16045

Clause-②: yes (widening)

Ruled at `5560224701` (director batch objectstack-ai#60, 2026-09-06, maintainer
verbatim 「同意」), re-affirmed by triage at `5724532096`: option A, a
readable declaration-text snapshot, ⛔ not a hash. The card body's three
mutually exclusive routes predate that ruling and were not re-litigated
here.

`@objectstack/spec` pinned its public surface on one axis.
`api-surface/` records each export as `name (kind)`, and a signature
change, a renamed interface field and a dropped union member move
**none** of those rows. The only shape pin was
`api-surface-signatures.json`: 27 rows, and reference-level even there.
This adds `api-surface-declarations/`, the declaration text the packed
build actually emits for every export of every published entry point,
and retires the 27 hashes it subsumes.

## The counts, re-derived on this head before the first generation

The ruling asks for this by name; the card's own numbers were
self-declared unverified and 12 days old.

| Number | Card | This head (`b33898f5d`) | Unit, and what would make it
something else |
|---|---|---|---|
| entry points | 17 | **17** | type entry points in the `exports` map —
those whose `require.types` ends in `.d.ts`. Adding or removing one such
subpath. |
| `exports` map entries | (not stated) | **19** | every key in the map.
The extra two are `./openapi.json` and `./package.json` — asset subpaths
with no declaration at all, filtered out by the same `.d.ts` test
`build-api-surface.ts` has always applied. ⇒ premise 1 resolved: **17 is
right and the map did not grow**; 19 counts two things that were never
entry points. |
| pinned rows | 5309 | **5336** | `name (kind)` rows summed over the 17
`api-surface/` shards. +27 since the card. Ratio unmoved: 27/5336 =
0.51%, so the headline 99.5% stands. |
| distinct exported names | (not stated) | **5200** | (entry, name)
pairs. The gap to 5336 is dual-declared names, which are two rows by
design. |
| signature hashes | 27 | **27** | top-level keys of
`api-surface-signatures.json`. Bright control: the first value really is
a `sha256:` string, so this counts signature entries and not empty
objects. |

Premise 3 also holds: all 17 packed `.d.ts` files exist and resolve
through the map (3,215,437 bytes for the root entry down to 13,081 for
`./integration`). No entry point lacks a packed declaration, so the gap
the dispatch reserved for itself did not open.

## What the artefact costs — premise 4, which nobody had costed

| | |
|---|---|
| shards | 17, one per entry point |
| declaration blocks | 5336 |
| bytes | **12,661,943 (12.08 MiB)** |
| lines | **237,706** |
| gzipped | **1,071,825 (1.02 MiB)** — against this package's ~17.57 MiB
compressed `dist`, so about **+5.8%** of tarball |
| largest shard | `system.txt`, 3,592,701 bytes / 73,283 lines |
| median declaration | **81 bytes** |
| skew | the 20 largest declarations hold **~65%** of all bytes; four
exceed 20,000 lines each (`EnvironmentArtifactSchema` 21,868,
`ObjectStackDefinitionSchema` and `ObjectStackSchema` 21,851,
`ChangeSetSchema` 20,395) |

Stated plainly, as the dispatch asks, and ⛔ not as a veto: the packed
`.d.ts` is a tsup dts rollup, so a Zod schema's declaration is its
**fully expanded** structural type. That expansion is exactly what makes
an inner field rename visible — and it is also why a single schema can
produce a 21,000-line diff. The ruling's stated reason for choosing text
over a hash is that the contract-review seat reads the diff; that
reasoning holds per declaration and is worth a second look at the top
twenty. One reading, for whoever wants it: 31% of declarations hold
97.7% of the bytes, so nothing cheap is available by trimming the tail.

## Both instruments, measured on one tree at one commit

The card's thesis is that the old pin cannot fail on a shape change. Not
argued — ablated, with the mutation proven on disk by blob hash and the
mutation proven to have reached `dist/` before any verdict was read.

**A. the source-level control — a renamed interface field, the card's
own class.** `JobRunOutcome.reason?` renamed to `degradationReason?` in
`packages/spec/src/contracts/job-service.ts` (blob `363443e2` to
`d4b1520c`), spec rebuilt, `ablation-dist-preflight` exit 0 confirming
the marker reached the built artefact:

```
check:api-surface              exit=0    "public API surface unchanged"      [BLIND]
check:api-surface-declarations exit=1    "~ JobRunOutcome (interface)"       [SEES IT]
```

Restore leg: blob back to `363443e2`, rebuilt, `ablation-dist-preflight
--absent` exit 0 (marker gone from all 214 built files), `git diff HEAD`
clean, gate back to exit 0.

**B. the gate can fail on its own artefact.** One field renamed inside
`qa.txt` by hand (blob `3f5efb04` to `5b86fec2`, injected occurrences 1,
deleted text 0): exit **1**, attributed to `TestSuiteSchema (const)`,
failure text naming the regenerate command. Restored to the HEAD blob,
`git diff HEAD` empty: exit **0**.

## The retirement, and the coverage proof the ruling demands

All **27** signature names resolve to a declaration block in
`api-surface-declarations/root.txt`, **0 missing** — enumerated from
`defineAction` through `defineWebhook`, each as `(function)`.

One honest qualification, because the subsumption is not uniform. For
those 27 factory declarations the text is `declare function
defineAction(config: z.input of ActionSchema): ActionParsed;` — a type
**reference**, exactly as blind to an inner-key narrowing as
`typeToString` was. What is gained is not sharper text on the 27; it is
the **5309 other declarations**, including `ActionSchema` itself, whose
own expanded block is where such a narrowing shows up. So the retirement
is a strict superset of pinned declarations, not an equal trade. Nothing
published read the retired file — it was never in this package's
`files[]`.

## Where it lands, and why there

- Generator: `packages/spec/scripts/build-api-surface-declarations.ts`,
beside the eight sibling artefact generators, reading the same input
through the same `collectEntries` logic. The ruling says "one generator
script under `scripts/`"; this reads that as the directory the whole
family lives in, because the artefact reads the **built dist** and only
the lane that builds spec can run its gate.
- Artefact: `packages/spec/api-surface-declarations/ENTRY.txt`, a
sibling **directory** of `api-surface/`. Not inside it: `listShardNames`
throws on any file in that directory that is not a `NAME.json` shard, so
`api-surface/` is closed by construction. No existing
`api-surface/*.json` is regenerated by this PR (`check:api-surface`
green throughout), which keeps it clear of PR objectstack-ai#18688 and PR objectstack-ai#18319.
- Gate: `check:api-surface-declarations`, a step in lint.yml's `Type
Check · consumer gates` lane after the two build steps, with
`check:api-surface` and the other dist-reading gates. **No new required
context** — a step in an existing lane. Registered in the
`check:generated` ledger, in `REGEN_ARTIFACTS`, and in `.gitattributes`
as `merge=os-regen`.
- Sharded per entry point from day one, for the reason its neighbour is:
the merge queue rebuilds server-side where no custom driver runs, so two
PRs sharing one generated file evict the second. Pit 1 from `5715457322`
is answered by the layout rather than by an assumption — and
`check:merge-driver`, which reconciles `.gitattributes` against
`REGEN_ARTIFACTS` in both directions, is green over the swap.
- Published, with the reason the gate demands. `check:published-files`
refuses a `files[]` entry that carries none; the registered line says
what a consumer does with it — read two published tarballs and see
*which declared shape* moved between releases, the question
`api-surface` cannot answer. If 1.02 MiB of tarball is judged too much,
one line of `files[]` removes it without touching anything else.

Three registries had to learn about the new gate, each because it
discovered the gate on its own rather than because a list named it:

- `check:published-files` — demanded the reason above.
- `scripts/pm/dispatch-gates.mjs` — its live manifest edge gave the new
gate a population before anything listed it, which is the eighth member
of a class whose seventh was recorded the same way. Declared as
`CLASS_EIGHTH`, with a case asserting the edge really reaches it.
- `scripts/pm/check-widening-tells.mjs` — `PUBLISHED_SURFACES` is
derived from `REGEN_ARTIFACTS`, so retiring the signatures row dropped
it off that surface and reddened two self-test cases. Both are
retargeted to state the retirement as a counterfactual (the surface
follows the table, not a literal); ⛔ the new artefact is **not** added
to that surface, because the ruling assigns "is a snapshot diff a
Clause-② signal" to the skills seat by name and out of this card's
scope. Both directions are now pinned, so the boundary is declared
rather than forgotten. 483 cases pass, up from 481.

## Verification

- **Gate families**: derived with `node scripts/pm/dispatch-gates.mjs
--repo objectstack-ai/objectstack --commands` from the merge base, 120
commands, every exit code redirected to a file and read back. **All 120
green.** Four returned exit **3** PREREQUISITE NOT MET on first pass
(`check:doc-formula-expressions`, `check:dual-build-cjs-loads`,
`check:lean-entry-closure`, `check:type-check-debt`); each names a
build, each was built and re-run green, and none is recorded as a
finding. Reconciled with `--ran`.
- **Tests**: `@objectstack/spec` local project **488 files / 14,182
tests passed**; the tooling suites that name the edited scripts, both
projects, **10 files / 220 tests passed** (`sharded-artifacts`,
`check-generated-ledger`, `dist-freshness`, `dist-freshness-adoption`,
`api-surface-dual-kind-rows.pin`, `build-schemas-check-mode`,
`def-key-collisions`, `root-index`, `export-list`,
`docs-import-surface`). `pnpm --filter @objectstack/spec typecheck`
green.
- **eslint, the union rather than a narrowing**: `eslint .
--no-inline-config --format json` at `b33898f5d` examined **6856
files**, **0 errors, 0 warnings**, exit 0. The population is eslint's
own config resolution and the count is read from its JSON output;
type-aware linting is not enabled in `eslint.config.mjs` (no
`parserOptions.project`, no typed rules), so this diff cannot move an
untouched file's verdict either way.
- **Control bytes**: `check:nul-bytes` green over 8906 files, plus a
direct scan of all 31 changed paths for the wider control-byte class —
no matches.
- `scripts/check-single-claim-paths.mjs` in the diffstat is **not
mine**: it arrived with the one-commit `origin/main` merge (`16cb493d5`)
this PR carries.

## Acceptance notes

- `.claude/skills/spec-property-retirement/SKILL.md` line 124 lists
`api-surface-signatures` as an instance of a retirement shape, and that
row goes stale with this landing. ⛔ Left untouched on purpose:
`.claude/**` is a governed surface, so editing it would make this whole
PR maintainer-landed for a one-word prose nit. Noted, not filed.
- `packages/spec/scripts/build-schemas.ts` line 830 carries the same
stale mention. Left untouched because PR objectstack-ai#18952 holds that file; noted,
not filed, with the later lander as the natural carrier.
- Three files in this diff are held by open PRs and were edited anyway
because the retirement forces it, not by choice:
`scripts/pm/check-widening-tells.mjs` (PR objectstack-ai#18948),
`scripts/pm/dispatch-gates.mjs` (PR objectstack-ai#18903) and
`.github/workflows/lint.yml` (PRs objectstack-ai#18946, objectstack-ai#18889, objectstack-ai#18414). All are
hand-written files where a text conflict is visible rather than silent,
and all three of my hunks are small and far from theirs. Whoever lands
second resolves.
- The top-20 skew above is a reading, not a finding: no gate is wrong
and nothing is unenforced. It is recorded here because the ruling's own
justification for text over hash is per-declaration readability, and at
21,000 lines a declaration that argument thins out.

## 维护者速读(草稿)

**改了什么。** `@objectstack/spec` 从今天起为它的**每一个**公开导出留一份"形状快照" —— 不是哈希,而是打包后
`.d.ts` 里那段声明原文,按入口点分成 17 个文件签入仓库,并配一道 CI
闸门:重新生成后对不上就红,失败信息里直接给出重新生成的命令。同时退休了旧的 27 条签名哈希文件。

**为什么改。** 原来的 pin 只记"某个名字还在不在",5336 行里只有 27
行能看出"形状变没变"。也就是说:把一个接口字段改名、砍掉一个联合成员、改一个函数签名 —— 这些都是会让客户升级后编译失败的破坏性改动 ——
全部一路绿灯。本次 PR 里有实测:改了 `JobRunOutcome` 的一个字段名之后,旧闸门 `check:api-surface`
退出码 **0**(看不见),新闸门退出码 **1**(点名了那个 interface)。路线是 2026-09-06 决策批次 objectstack-ai#60
里您逐字「同意」的那一条。

**风险与代价(含回滚)。** 代价是体积:12.08 MiB 文本、23.7 万行,压缩后 1.02 MiB,相当于 npm 包增长约
5.8%。更值得注意的是分布极不均匀 —— 最大的 4 个 schema 各自超过 2 万行声明文本,一旦它们变动,复核席位面对的是一份 2
万行的 diff;而裁决选"文本不选哈希"的理由恰恰是"diff 可读"。这一点我按实测如实报告,未自行改动路线。回滚成本很低:从
`files[]` 去掉一行即可停止随包发布;整道闸门回滚就是撤销本 PR,不留任何数据迁移。

**席位意见。**

**你要做的。** 只有一件事需要您判断:12 MiB / 23.7 万行这个量级,以及最大 4 个 schema 的 diff
可读性,是否仍符合当初选 A 方案时的预期。若认为需要收窄,那是裁决层面的一次增补,不是本 PR 的返工。其余部分已按裁决落地并自证。
