Closes #1522

Status

Implement: done (4/4 green), audit done Review: round 1, round 2, fix-check passed, 0 open Hardware: n/a Gate: waiting for the stack
Next: the feature's next task (#1523) stacks on this PR

Done when

• The checks from toolchain.md pass, the protocol bump check included. (protocol 86 to 87, src/contract/protocol.ts; hooks green on push) — CI green on 6ad6fc9; protocol bump in the diff
• The four Tests lines pass. Worker: src/leasing/create-leasing.test.ts ("a caller re-sending a chosen lease id whose lease ended within the window ..."). Gateway: e2e/gateway-fleet.test.ts ("through a gateway, a caller re-sending a chosen lease ID after its lease ended gets LEASE_ENDED"). Config: src/core/config.test.ts ("an operator's lease.endedIdRetentionMs is checked at load ..."). Error table: src/contract/errors.test.ts ("a caller refused with LEASE_ENDED ...") — audit probed 6/6, review round 2 and fix-check probed R1–R6
• configuration.mdx has the lease.endedIdRetentionMs row; errors.mdx has LEASE_ENDED and the reworded exit-13 line; events.mdx and EVENTS.md list lease-ended; the gateway manual's Persisted line names the ended ids and a Known gap says a lease that ended while the gateway was down is not recorded by it; gateway/routing.mdx says what a retried ended id gets through a gateway, that gap included. — claims lens rounds 1 and 2; the manual's Known gap line was cut to meet the 8000-character manual limit, and the gap stays in ADR 0074 and gateway/routing.mdx (see Assumptions)

Assumptions

• Assumption: the existing agent-device edge test that re-grants a lease id right after it ended — it now advances the fake clock past the 24 h window before reusing the id, so its claim (routing forgets an ended phone lease) is kept and the id is outside the window.
• Assumption: FleetLeaseEntry.idChosenByRequester is optional (and mirrored on the module-facing FleetLease) — the smallest change that leaves every other entry constructor untouched.
• Assumption: the gateway manual carries no Known gap line for a lease that ended while the gateway was down — the manual is at the 8000-character limit src/docs-manuals.test.ts checks; ADR 0074 and gateway/routing.mdx state the gap.

Walkthrough

The change adds configurable retention for requester-chosen lease IDs after leases end. Workers persist ended IDs in the registry, and gateways persist IDs when they learn that a lease ended. During admission, each rejects a retained ID with LEASE_ENDED, including the ID and end time. The change updates event and HTTP error contracts, gateway lease-end tracking, tests for persistence and expiration, and documentation. The protocol version changes from 86 to 87.

Merge Risk: Low · previous review 0d83c

Docs and the MCP tool description say ended lease IDs are refused for 24 hours, but operators can configure a different period. Agents and users may be misled on custom configurations. The runtime behavior looks correct. Qualify the text as "24 hours by default" before or soon after merging.

Full details: Title check

Explanation

The title names the main change: a caller's chosen lease ID is refused with LEASE_ENDED after its lease ended. The changeset adds ended-lease-ID persistence, the LEASE_ENDED error (HTTP 409, CLI exit 13), the lease-ended rejection reason, and the endedIdRetentionMs config setting, all of which match this title.

Full details: Description check

Explanation

The description links issue #1522 and lists the checks, the protocol bump from 86 to 87, the documentation updates, and the assumptions for this change. These items match the changeset, so the description is related to the changes.

Full details: Linked Issues check

Explanation

Issue #1522 is the only directly linked issue, and it is open. Its coding requirements are covered by the whole-PR summary (base 70249c5 to head 0d83c2f):

• Persistence and retention: src/core/registry-schema.ts adds schema v6 with the ended_lease_ids table. src/core/registry-rows.ts adds write, prune, and read helpers. src/core/registry.ts records chosen IDs at lease removal in the same commit, prunes rows older than endedIdRetentionMs, and exposes endedLeaseId.
• Config: src/core/config.ts adds lease.endedIdRetentionMs with a 24-hour default and positive-number validation. src/core/config.test.ts covers default, valid, and invalid values.
• Worker admission: src/leasing/lease-acquisition-coordinator.ts checks ended IDs after the live-ID check and throws leaseEndedError. Live IDs still return LEASE_ID_TAKEN. Tests are in src/leasing/create-leasing.test.ts.
• Gateway: src/gateway/ended-lease-ids.ts adds StateEndedLeaseIds and MemoryEndedLeaseIds. src/gateway/lease-index.ts fires onEnded for direct removal, worker-reported removal, and two missing snapshots. forgetWorker notifies removal listeners only. src/gateway/fleet-coordinator.ts rejects retained IDs with lease-ended. Tests are in e2e/gateway-fleet.test.ts and src/gateway/ended-lease-ids.test.ts.
• Errors and protocol: src/contract/errors.ts adds LEASE_ENDED with leaseId and endedAt details, HTTP 409, and CLI exit 13. The message includes the ID and the ISO end time. src/contract/protocol.ts moves the protocol from 86 to 87. src/bus/index.ts adds the lease-ended reason.
• Documentation: configuration.mdx, errors.mdx, events.mdx, EVENTS.md, gateway/routing.mdx, and the using-devices pages are updated. routing.mdx states the gateway-down limitation.

The gateway-down limitation is preserved in code (no recording when the gateway is down) and in routing.mdx. The gateway manual omits its Known gap line, which the PR states is a character-limit trade-off. That is a documentation detail, not a coding requirement, so it does not change this result. The summary does not show the full test results. The PASS rests on the summary and the PR's reported test names, not on a fresh run.

Full details: Out of Scope Changes check

Explanation

The changed files support #1522:

• Test-fixture updates set lease.endedIdRetentionMs in test configs (for example src/core/nuke.test.ts, src/core/reaper.test.ts, src/leasing/*.test.ts, src/gateway/test-fleet.ts). These keep the new config key in each fixture.
• src/agent-device/edge.test.ts advances the fake clock past the 24-hour window before reusing a lease ID. This keeps the existing routing assertion valid under the new retention rule.
• src/source-hygiene.test.ts raises two SHRINK_ONLY limits for files that grew with the new tests and admission check.
• src/http/lease-declarations.ts, src/http/openapi.test.ts, src/mcp/server.ts, and src/modules/types.ts (idChosenByRequester) expose the new error code and metadata to HTTP, MCP, and module consumers.
• Internal AGENTS.md files describe the new rules.

One minor item is not tied to a new behavior: docs/internal/EVENTS.md and events.mdx also clarify when a gateway emits lease-id-taken. This is a documentation clarification of the existing conflict path, and it is closely related to the LEASE_ID_TAKEN behavior that #1522 preserves. No demonstrated unrelated product behavior was found in the summary.

Describe the configured refusal period in the MCP tool.

If an operator changes lease.endedIdRetentionMs, this description still says an ended ID is refused for 24 hours. State that the period is configurable and that 24 hours is the default. Agents otherwise receive an incorrect rule for the configured daemon.

Qualify 24 hours as the default.

If an operator changes lease.endedIdRetentionMs, this row gives the wrong refusal period. Say “within lease.endedIdRetentionMs (24 hours by default).” Apply the same correction to the changed sentence in website/src/content/docs/docs/using-devices/lease-lifecycle.mdx at Line 140.

src/http/lease-declarations.ts: 1

256-256: Minor · Data Integrity & Integration · Quick win

Declare the LEASE_ENDED fields in the 409 schema.

The HTTP mapper preserves leaseId and endedAt, but the response schema does not describe them. Generated API documentation and typed clients therefore lack their declared types.
