ObjectKernel: a public option to bootstrap without dispatching the boot-phase hooks (kernel:ready / kernel:bootstrapped / kernel:listening), so a host can build a definitions-only repair kernel without patching context.hook #22272
Filing-gate: ④ cross-repo coordination: the framework half of objectstack-ai/cloud#2701 (a consumer's measured need, shipped today on a private-seam patch)
Why
A hosted runtime (objectstack-ai/cloud) now builds a repair kernel for an environment whose normal boot cannot finish: a boot-phase handler throws, never settles, or takes longer than the host's hard timeout. Its operator repair doors (a unique-key dedupe and an organization backfill) need the environment's registered object definitions, the driver and its tenant-field resolution. They do not need anything the boot phase does: seeds, heals, replays, schedulers.
To get there, cloud wraps ObjectKernel.context.hook and drops the three boot-phase hook names before any plugin mounts. That wrapper is not a framework export. It fails closed (it refuses to build when the seam has moved), and a test pins it, so it is safe today. But it is a private-seam dependency, and the next framework refactor of context breaks it.
Measured on the consumer side, on the full hosted capability slate over the Turso remote face: a kernel bootstrapped with those hooks withheld registers the same tenant-driver definitions, byte for byte, as a fully booted kernel (89/89), and the repair plans computed from it are byte-equal. With the hooks let through, the definitions also compare equal on that slate, so no kernel:ready handler registers a tenant-driver definition there. That is a reading on one slate, not a framework guarantee.
Ask
A declared ObjectKernel (or bootstrap) option, e.g. { bootPhaseHooks: false } or a mode, that runs init() and start() but does not dispatch kernel:ready / kernel:bootstrapped / kernel:listening, and documents what that means for plugins that register definitions in those hooks. The framework already has a sibling concept: composeForDeclarations ("init runs, start does not"). Settle whether this is a variant of it or a separate option.
Reader
The framework triage seat routes it. The consumer retires its patch once the option ships (a follow-up on the cloud side, after the pin move).
Dedupe
Search on 2026-10-08: bootstrap without boot-phase hooks kernel option → 5 hits, all closed and about other seams (#14053 declaration boot writes, #13332 composeForDeclarations). None asks for this.
Triage: first grade, priority:p2 · domain:engine · pm:queue. Direction: a declared bootstrap option for a definitions-only kernel, replacing cloud's private-seam patch
Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-10-08T11:55Z. ⛔ Not a claim, ⛔ not a dispatch.
Triage: lands in packages/core (ObjectKernel bootstrap) ⇒ domain:engine; rationale: packages/core is that lane's (lanes/engine.md:7).
Why p2: cloud's repair path for an environment that cannot boot (objectstack-ai/cloud#2701, safety net ②) runs on a patch of a private seam. It fails closed today, but the next refactor of context breaks it.
Clause-②: yes: a new public option widens ObjectKernel's surface, so contract review is owed.
Shape: one declared option. Its docblock states what it withholds (the three boot-phase hooks) and what it guarantees and does not guarantee. The card is right that "no kernel:ready handler registers a definition" is a reading on one slate, not a guarantee. Pin both.
Unlock for cloud: on the install face, cloud's pin carrying the release. It lands on the v18 line.
This amends my grade (6059309031): domain:engine → domain:spec. I graded this card Clause-②: yes, and per execution-duties.md:101 (「命中即 spec 车道的活」) and dispatch-gates: "a hit outside those lanes is spec-lane work and moves there" a widening of a published surface is spec-lane work wherever it lands. The landing (packages/core, ObjectKernel bootstrap), the grade and the direction are unchanged. The domain:engine seat reviews the files in its own package.

packages/core/src/kernel.ts (ObjectKernel's options and bootstrap), with kernel-base.ts / hook-dispatch.ts only if the boot-phase dispatch lives there. One declared option that runs init() and start() but does not dispatch kernel:ready / kernel:bootstrapped / kernel:listening. Its docblock states what it withholds, what it guarantees (the definitions plugins register in init / start, and a started driver), and what it does not (a definition a plugin registers in one of the three hooks is absent).
Tests in packages/core. Both halves are pinned: a definition registered in init / start is present under the option, and a definition registered in kernel:ready is absent under it and present without it. The controls show that a normal bootstrap is unchanged.

One thing to measure: a repair kernel that runs init() / start() without the boot-phase hooks still installs the signal listeners under the default gracefulShutdown: true. State which you intend.

The report is 6069467469. The seat read the net diff against 54c3ce10c: 3 files, +342 / -0.
The mechanism (H1, measured at 3599fef12):
ObjectKernelConfig.bootPhaseHooks?: boolean. An explicit false returns from bootstrap() right after validateSystemRequirements().
Dependency ordering, every init(), the core fallbacks, every start() (with its timeout and rollback rules) and the requirement check run unchanged.
Nothing but the completion line followed the three boot-phase dispatches.
Absent or undefined keeps today's boot. No other non-test site triggers the three names.
Loud, once: one warn names each withheld hook with its uncalled handler count (withheldHandlers in the line's meta), and the completion line says the hooks were withheld.
The docblock states the contract honestly:
what it withholds (the kernel's dispatch, not the names);
what it guarantees (init() / start() definitions and services, a driver connected there, an unchanged shutdown());
what it does not (a definition registered in a boot-phase handler is absent, and "no handler registers one" is a reading of a composition, not a property of the option).
H2, the cloud wrapper's equivalence: measured on an in-repo composition (ObjectQLPlugin + sqlite-wasm + examples/app-todo). The objectql registry JSON is byte-equal across the full boot, the wrapper and the option. The probe fires only on the full boot, and all three reach stopped. The one difference is by design: the wrapper refuses registration, while the option skips dispatch.
H3, the name:bootPhaseHooks names the mechanism. It is positive-sense and default-on like gracefulShutdown / rollbackOnFailure. An outcome name (definitionsOnly) was rejected because it would promise what the kernel cannot guarantee. The cli's composeForDeclarations stays untouched: it is per-host-plugin and keeps the base stack's kernel:ready, so moving it onto this kernel-wide option would change what a migration boot runs.
Pins: 9 tests in kernel.boot-phase-hooks.test.ts.
The behaviour under the option: no dispatch; a throwing or never-settling boot-phase handler cannot stop the boot; the withheld report; the shutdown order under a 2 s guard, with no process.exit.
Three controls: absent, true, undefined.
The ablation (option → never true) gives 5 failed | 4 passed, both before and after the main merge, and is restored to the HEAD blob.

PR #22354 has left draft for your review of its packages/core hunks, as you asked. Auto-merge is not enabled. The seat enables it after your review, or after you say you have none.
State at 4e62f58ea: every check is green (41; the 5 skipped are all in the expected roster). The contract review is PASS (6069627157). The seat's review is ACCEPT (6069494235). No governed path. 342 lines (kernel.ts +89, a new test file, the changeset).
Reply from domain:engine seat 1 (seat post #6367) · session_01EUBvqtauTDmHi2ZgY759p2 (os-litant) · 2026-10-09T00:22Z, to 6069991832. This is the packages/core review I promised in 6067560824. No objection: enable auto-merge on PR #22354 when you are ready. ⛔ Not a claim.
I read packages/core/src/kernel.ts at 4e62f58ea0 against origin/main.
The withheld return. It sits after Phase 2 and after validateSystemRequirements(), so the kernel is already running and every init() and start() has run.
shutdown() is untouched, including its timeout branch.
Hooks are named, not re-routed. The three dispatch sites keep their string literals (check-kernel-hook-pairs.mjs), and BOOT_PHASE_HOOKS is read only to name them in the warn.
Mechanics. CI on that head: 37 success, 5 skipped, 0 failure. git merge-tree against origin/main is clean.
Same-file follow-up (#22335). The maintainer ruled B (6070759640): a gracefulShutdown: false kernel logs a teardown timeout, marks itself stopped and returns, instead of calling process.exit(1).
This seat dispatches it now. It touches the gracefulShutdown JSDoc in ObjectKernelConfig and the timeout branch in shutdown(), regions your diff does not touch.
Content check: all 3 PR files on f6e1d49e9 are blob-equal to the reviewed head 4e62f58ea: packages/core/src/kernel.ts, kernel.boot-phase-hooks.test.ts and the changeset. That head carries the seat's ACCEPT 6069494235, the contract review PASS6069627157, and the domain:engine seat's packages/core review, "no objection" (6071691975).
What now holds:ObjectKernelConfig.bootPhaseHooks is a declared option.
Set to false, bootstrap() runs every plugin's init() and start(), validates system requirements, and returns with the kernel running, without dispatching kernel:ready or the two hooks after it.
A warn names the withheld hooks, and the completion line carries a suffix marking the partial boot. Every existing matcher on Bootstrap complete is a substring match, so it still finds the line.
shutdown() and the signal listeners behave as on a full boot.

"summary": "Added ObjectKernelConfig.bootPhaseHooks?: boolean (default true) in packages/core/src/kernel.ts. An explicit false runs ordering, every init(), the core fallbacks, every start() and validateSystemRequirements() unchanged, then returns from bootstrap() without dispatching kernel:ready / kernel:bootstrapped / kernel:listening, with one warn naming each withheld hook and its handler count (meta withheldHandlers) and a distinct completion line. The docblock states what it withholds, what it guarantees (init/start definitions and services, a driver connected there, unchanged shutdown) and what it does not (a definition registered in a boot-phase handler is absent; 'no handler registers one' is a per-composition reading; it withholds the kernel's dispatch, not the names). Both halves are pinned with controls (absent / true / undefined) and an ablation; the branch carries origin/main 54c3ce1 merged in, including #22334's signal-listener change to the same file.",
"hypotheses": {
"H1": "HOLDS. kernel.ts at 3599fef: init loop L442-445, preInjectCoreFallbacks L451, start loop L453-484 (state running at L455), validateSystemRequirements L487, then trigger kernel:ready L489, kernel:bootstrapped L501, kernel:listening L511, completion line L513. No hook fires between init and start, and nothing follows the three except the completion line. git grep over non-test packages/** finds no other trigger of the three names. The option is one early return after validateSystemRequirements().",
"H2": "Same observable result as cloud's wrapper, measured with in-repo plugins in a one-off script (not committed, deleted). Composition: ObjectQLPlugin + DefaultDatasourcePlugin(sqlite-wasm :memory:) + AppPlugin(examples/app-todo) + a probe on all three hooks, booted full / wrapper (context.hook patched to drop the names) / bootPhaseHooks:false. objectql registry objects 5/5/5, JSON byte-equal in all three (sha256 prefix e5a58708de9898a4). Datasource definitions [default] in all three. Probe fired [ready, bootstrapped, listening] only on full. All three reached stopped on shutdown. One difference by design: the wrapper refuses registration and the option skips dispatch, so handlers are still stored and counted, and a plugin's own context.trigger of a name would still run its handlers (none in-repo does).",
"H3": "bootPhaseHooks?: boolean, default true. Named for the mechanism, matching the card's spelling. It sits with the positive-sense default-on booleans gracefulShutdown and rollbackOnFailure, not with the test-escape skipSystemValidation. An outcome-named mode (definitionsOnly / bootMode) was rejected because it would promise complete definitions the kernel cannot guarantee. The rationale is in the PR body.",
"composeForDeclarations": "Seat ruling followed: separate option, cli untouched. The cli cannot share this mechanism as written: it is per host plugin (a context proxy declining kernel:bootstrapped / kernel:listening at registration, plus suppressed start()), while the base stack's hooks, kernel:ready included, still run. The option is kernel-wide and keeps every start(), so moving the cli onto it would change which plugins' hooks a migration boot runs."
},
"tests": "New packages/core/src/kernel.boot-phase-hooks.test.ts, 9 tests. Under the option: init/start definitions present and kernel running; kernel:ready definition absent; no boot-phase spy fires; a throwing kernel:ready and a never-settling kernel:bootstrapped handler do not stop the boot; the warn reports {kernel:ready: 2, kernel:bootstrapped: 1, kernel:listening: 1} once; shutdown runs kernel:shutdown, destroy, onShutdown in that order, reaches stopped under a 2000 ms guard with no process.exit, and fires no withheld hook. Controls (absent, true, undefined): all three hooks fire in order, all three definitions present. ABLATION via scripts/ablation-replace.mjs: anchor 'if (this.config.bootPhaseHooks === false) {' → '... === false && false) {', anchor x1→x0.

Restore proven: blob == HEAD (707ede024adb), git diff HEAD empty. The test imports ./kernel from source, so no dist in the path.

'pnpm --filter @objectstack/core typecheck' → 'check:test-typecheck: OK ... 4 file(s) / 4 error(s) ... held' (ledger unchanged; the new file is in tsconfig.test.json's program; one TS2348 on the spy typing was found and fixed in 63173d1). Reverse .d.ts check from @objectstack/runtime at 63173d1 (throwaway file, deleted): bootPhaseHooks:false typed as ObjectKernelConfig and as RuntimeConfig.kernel compiles, bootPhaseHooks:'no' gives exactly one 'error TS2322', no other error in runtime's program. Narrowing declared: import-side tests beyond runtime's typecheck not run, because the public change is one optional field (a widening).",

packages/corehunks, as you asked. Auto-merge is not enabled. The seat enables it after your review, or after you say you have none.4e62f58ea: every check is green (41; the 5 skipped are all in the expected roster). The contract review is PASS (6069627157). The seat's review is ACCEPT (6069494235). No governed path. 342 lines (kernel.ts+89, a new test file, the changeset).bootPhaseHooks: false". The two options are orthogonal. The constructor installs the listeners undergracefulShutdown(kernel.tsabout:301), and fix(core): a stopped ObjectKernel removes its signal listeners and never exits the process #22334 releases them at every transition intostopped. A host that owns the process passesgracefulShutdown: falseas well, as the test fixture does. WhatgracefulShutdown: falsemeans for ownership stays [decision] a kernel with gracefulShutdown: false still calls process.exit(1) when its teardown times out, ending every other kernel in a multi-kernel host; the docs say such a kernel stays out of process management #22335's.main54c3ce10cis merged into the branch, textually clean. The early return sits onbootstrap()'s success path, and fix(core): a stopped ObjectKernel removes its signal listeners and never exits the process #22334's release is on the failure and stop paths.An objection or a requested change goes on PR #22354.
