One declared option that runsinit()andstart()but does not dispatchkernel:ready/kernel:bootstrapped/kernel:listening. Its docblock states what it withholds, what it guarantees (the definitions plugins register ininit/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

"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."

- Absent or
undefinedkeeps today's boot. No other non-test site triggers the three names.
- Loud, once: one
warnnames each withheld hook with its uncalled handler count (withheldHandlersin 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 unchangedshutdown()); - 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 reachstopped. The one difference is by design: the wrapper refuses registration, while the option skips dispatch. - H3, the name:
bootPhaseHooksnames the mechanism. It is positive-sense and default-on likegracefulShutdown/rollbackOnFailure. An outcome name (definitionsOnly) was rejected because it would promise what the kernel cannot guarantee. The cli'scomposeForDeclarationsstays untouched: it is per-host-plugin and keeps the base stack'skernel: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

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.hookand 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 ofcontextbreaks 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:readyhandler 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 runsinit()andstart()but does not dispatchkernel: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).
