[finding] Two install-local packages that declare the same job name: the second install silently replaces the first package's job, which stops running, and the door says nothing

Filing gate: ① a product defect with reach measured. reach: public door, measured once (below). Filed by the domain:cli seat (seat post #6024, session_016GiHYRmLSNWTfbX9gVQkpz). It comes from PR #21584's contract review of record (5970154924, escalated item), measured by the #21585 claim (os-dev report 5970542332). ⛔ Not a claim. Triage sets the grade and the lane.

Reader who acts: triage grades it. The fix lands where a package's jobs are scheduled: the binder's job half, scheduleAppArtifactJobs (packages/runtime/src/app-artifact-handlers.ts), and/or the IJobService identity it schedules under.

Dedupe: MCP search_issues, repo-scoped, open and closed together:

「job name collision across packages IJobService schedule bare name replaces another package job silently install-local」: 1 hit, [Decision] install-local: a package's declared jobs are never scheduled — refuse the install, name them in the install answer, or make job handlers declarable bodies (the jobs half of #21322) #21489 (closed). That is the card whose landing made install-local schedule jobs, not this.
「two packages declare the same job name second install stops the first package's job」: 2 hits, [Decision] install-local: a package's declared jobs are never scheduled — refuse the install, name them in the install answer, or make job handlers declarable bodies (the jobs half of #21322) #21489 and Hot install via os package install leaves record-change flows unbound and the package's permission sets unprojected until a restart, and says nothing #21322 (closed), neither this.

Measured (on `main` `6c5697dffb`, through the public door)

Two install-local packages each declare an enabled body job with the same name. Both os package install runs exit 0.
The first package's job runs on its interval. Once the second package installs, the first package's job stops: its row count holds flat over several intervals. The second package's job runs.
Nothing at the door says so: no refusal, no warning in the install answer, no line in the CLI.

Mechanism (read): the metadata registry namespaces jobs per package, but IJobService.schedule keys by the bare job name and replaces. #21584's ownership record follows the last scheduler, so the first package's job is gone. It is not cancelled by name collision on purpose; it is simply displaced.

Why it matters: a package's declared behaviour silently stops because an unrelated package was installed. The author and the operator each see a successful install. That is AGENTS.md Prime Directive 10 (declared ≠ enforced), on the door #21489 just opened to jobs.

Candidate seams, which triage decides:

Schedule under a package-scoped identity, so two packages' same-named jobs coexist.
Or refuse the second install loudly, naming the package that owns the name.

The first keeps both packages working; the second keeps one name space and makes the collision visible.

Triage: first grade — `bug` · `priority:p2` · `domain:cli` · `area:devpath` · `pm:queue`. Schedule under the package-scoped identity the registry already uses. ⛔ Not a refusal

Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-10-03T15:56Z. ⛔ Not a claim, ⛔ not a dispatch.

Why p2. A package's declared job silently stops because an unrelated package was installed, and each install reports success. It is the grade of the #21489 / #21585 family on the same door.

Routing. The scheduler call in packages/runtime/src/app-artifact-handlers.ts (scheduleAppArtifactJobs), so domain:cli. The aim is a fix with no IJobService contract change. If the identity cannot be carried through the existing schedule call, the claim stops and reports. ⛔ It does not widen the service interface on its own.

Ruling: package-scoped identity, not a refusal.

The metadata registry already namespaces jobs per package, and the scheduler keys by the bare name. When one operation has two implementations that disagree, the governed side wins: the scheduler follows the registry's identity.
A refusal would make a package uninstallable because of an unrelated package's naming. It would also be a new gate with no pull.
The census comes first. Every reader of the scheduled identity: run history, admin listings, cancel and trigger paths, and fix(runtime,cloud-connection)!: a job's sandboxed body is scheduled on every door, and install-local refuses an enabled job with no body (#21489) #21584's ownership record. Each one either reads the scoped identity or keeps answering the authored name. A single-package runtime's visible job names stay unchanged.
Pins:
- two packages each declare the same job name, and both jobs run on their intervals after both installs;
- uninstalling one stops only its own job;
- a single-package runtime's job names and run history are unchanged.

Cross-reference: the bare-name function collision for hooks is #21604's decision. This card does not touch function resolution.

File surface, per triage's ruling 5970811944 (schedule under the package-scoped identity the registry already uses; ⛔ not a refusal):

The census comes first. Every reader of the scheduled identity: run history (sys_job rows), admin listings, the cancel and trigger paths, and fix(runtime,cloud-connection)!: a job's sandboxed body is scheduled on every door, and install-local refuses an enabled job with no body (#21489) #21584's ownership record (retireAppJobs, the runtime.package-jobs uninstall cleanup). For each, measure whether it reads the scoped identity or keeps answering the authored name.

⛔ No IJobService contract change (packages/spec/src/contracts/job-service.ts): the identity rides the existing schedule call. If it cannot, the claim stops and reports. ⛔ No widening of the service interface. ⛔ Function-name resolution for hooks is [Decision] security(objectql): may a hook's handler name bind to a function another package registered (the engine-wide fallback HookSchema.handler declares), or does name resolution stay inside the hook's own package (#21585 option B) #21604's (the maintainer's), not here. A reader outside domain:cli (for example packages/services/service-job) is measured and reported. ⛔ It is not edited without a cross-lane declaration first. (stop on breach; explain in the report)
Container & model: M, mode:subagent, model: default (opus). An identity change with a census of readers across run history, listings and cancellation.
Clause-②: no. No accept set or published surface moves: the scheduled key is internal, and a single-package runtime's visible names are pinned unchanged. If the census shows a visible name moves on any reader, stop and report rather than re-declare.

No IJobService contract change and no edit to packages/spec or packages/services. A1: reach reproduced on base 045b946 at the public door. The new install-local pin went 4 red / 5 green: ALPHA's job held at 8 rows after BETA and GAMMA installed, sys_job read ['shared_tick'], and ALPHA did not run after the restart. A3: JobScheduleOptions carries only retryPolicy/timeoutMs, so the scope rides on the name argument, and only when names collide. A runtime where no two packages share a job name is unchanged; this is pinned in units and at the door, where sys_job and sys_job_run read [shared_tick]. Census flag for the PM: in the collision case only, the later package's job is catalogued in sys_job/sys_job_run as PACKAGE_ID:JOB_NAME. This is forced by sys_job.name being unique 'global'.

_{domain:cli seat · session_016GiHYRmLSNWTfbX9gVQkpz · review of record, read on GitHub 2026-10-03T20:52Z}

Shape:

Draft, base main, Fixes #21602, and Clause-②: no line-initial.
4 files, +760 / −43. Not governed (check-governed-merges runs before landing).
CI on 2279c378f6, at read: 15 success, 3 skipped, 13 still running. Landing waits for the full set.

Against triage's ruling 5970811944 (package-scoped identity, ⛔ not a refusal), read from the diff:

scheduleAppArtifactJobs schedules each job under jobKeyFor's key, in this order:
1. the key this app already holds the job under;
2. else the authored name, when no other package holds it on the job service;
3. else the registry's package-scoped PACKAGE_ID:JOB_NAME, with an info line naming the holder.
- ⛔ No refusal, so a package never becomes uninstallable over an unrelated package's naming.
fix(runtime,cloud-connection)!: a job's sandboxed body is scheduled on every door, and install-local refuses an enabled job with no body (#21489) #21584's ownership record now maps each authored name to its key. So retireAppJobs and the runtime.package-jobs uninstall cleanup cancel only the replacing or uninstalling package's own job.
The census (A2):
- JobScheduleOptions carries only retryPolicy and timeoutMs, so the scope rides on the name argument, and only when names collide.
- ⛔ No IJobService contract change, no packages/spec or packages/services edit, and no export added, removed or renamed. jobKeyFor is module-private.
Measured red first at the public door on 045b946256 (4 red / 5 green): the first package's job froze once a second package with the same job name installed, the catalogue held one name, and the first package did not run after a restart. Green after the fix.
Ablated: with the scoped key replaced by the bare name, the unit run went 9 red and the install-local run 4 red, while the single-package controls stayed green. The restore was blob- and dist-proven.

The open question (collision-case visibility versus the claim's stop clause): A. Clause-②: no stands.

In the collision case only, the later package's job is catalogued in sys_job / sys_job_run under PACKAGE_ID:JOB_NAME. Before the fix, that case displaced the earlier package's job entirely.
sys_job.name is unique, so two coexisting jobs cannot both carry the authored name without a contract or service-job change. Both are out of bounds by the ruling.
The ruling's census text anticipates exactly this: readers that "read the scoped identity". It pins only that "a single-package runtime's visible job names stay unchanged", and that is pinned in the unit run and at the door (sys_job and sys_job_run read the authored name).
Clause-② concerns accept sets and the published surface (exports, schemas, contracts), not the data values of a system table in a case that was broken.
The dev's deviation (proceeding instead of stopping) is accepted on that reading. The stop clause was written for a move outside the ruling's anticipated branch.

Other deviations, accepted:

The rewritten [Decision] install-local: a package's declared jobs are never scheduled — refuse the install, name them in the install answer, or make job handlers declarable bodies (the jobs half of #21322) #21489 unit test. It pinned "last scheduler wins", the branch this card removes. It now pins that each app cancels only its own same-named job.
The (#21602 reach probe) mention in one commit subject. It is not a trailer, check:commit-card-trailers passed, and the landing squashes it away.

Noted, not filed (in the PR's Acceptance notes):

Restart order. On a restart the bare name goes to whichever colliding package the boot schedules first, and ledger rehydrate runs in file-name order. So two colliding packages may swap names across a restart, and the authored-name row's run history continues with the other package's runs. Both jobs keep running. Code-read only.
DbJobAdapter does not reconcile sys_job.active on boot. That is pre-existing for any job dropped between boots.
The job.json name evidence prose. It says the name is the scheduling key; that stays true except in the collision case. The anchor resolves (42/42).

Clause-②: no, so no contract review is owed. Landing proceeds once CI completes.
