ci(conformance): scheduled Electron recorder drift lane with its own failure sink (parked) #585

Generated by an AI agent (Claude Code) on behalf of @0monish during Wayfinder charting of the Electron compatibility program; rewritten 2026-10-07 by the doctrine-audit repair pass (change log at the end). Planning only — no implementation is authorized by this issue.

What to build

Pull this when goldens exist for a second family or a pin bump is proposed. It re-runs the recorder at the same pin on each OS (Linux under a virtual display, as Electron's own workflow does; macOS with Electron's persistence and crash-dialog prep). It routes any difference to a named failure sink and never re-records automatically. A difference enters the PR gate only through a reviewed PR that flips cells to unknown or updates goldens, receipts and cells together. Detailed design is deferred.

Spec gate: the first deliverable is a spec from docs/agents/spec-template.md, opened as a PR and stopped for human approval; implementation starts only at Status: approved.

Acceptance criteria

• A scheduled run with a deliberately altered golden produces a failure in the named sink, and no automatic re-record commit

Negative controls (each names the one mutation that must fail)

• Configuring the lane with any rerun or retry count above zero fails its routing review contract

External predecessors (outside this tracker)

• KEL-81 changed-path CI router as present on origin/main 8678c0d (KEL-81 Done); the lane extends that router and no live Linear issue owns a new lane

Ownership and gates

• Tracker of record: this GitHub issue (no live Linear issue covers it; owner decision Linear owner for repo-writing Electron-compat slices (owner decision: align to nearest Linear issue, else GitHub is the tracker of record) #517). Claims, status and handoffs happen here under docs/agents/workflow.md § Tracker issue (rule lands with docs(agents): record the #517 tracker-of-record rule in root AGENTS.md and the workflow claim protocol #520). Linear reference: KEL-237 (In Progress) carries a link to this issue.
• Blocking edges: native GitHub blocked-by links on this issue (open blockers only: feat(conformance): lifecycle-family tracer and shared Electron-arm recorder for the two-arm harness — main-process lifecycle fixtures (including first-launch activate) recorded under verified Electron 44.4.5 on macOS arm64, replayed under @keld/elect #495)
• Linear owners and predecessors (repair-time analysis; statuses as fetched 2026-10-07): Tracker of record: this ticket's GitHub issue, per the X06-D7 owner decision (Linear owner for repo-writing Electron-compat slices (owner decision: align to nearest Linear issue, else GitHub is the tracker of record) #517, closed 2026-10-06; adopted resolution: align to the nearest live Linear issue whose scope covers the work, otherwise the GitHub issue is the tracker of record). The nearest surface, KEL-81 (changed-path CI routing; Linear fetched 2026-10-07), is Done, so it is not live. Linear reference: a link on the fallback KEL-127 (Todo, unassigned); the map orchestrator posts it when the ticket is pulled.
• Review gates: none
• Platforms: Linux, macOS, Windows hosted runners (display needs unverified until a first run)
• Electron members covered: —

Out of scope

Corpus-app smoke and the product scoring run (X02-T6).

Notes

Parked by the YAGNI test: the drawio-desktop macOS first proof ships without scheduled drift detection. FACT (refuter receipt): Electron reruns its own suite up to three times on every non-ASAN lane. Size the lane expecting upstream-level flake, and never copy the reruns.

Change log (doctrine-audit repair, 2026-10-07)

• New parked ticket holding the weekly lane split out of X01-T2, plus the 'weekly recorder lane home and failure sink' fog item (rule 2; refuter A4 corrections; no-scheduled-workflow extra findings from both lenses).
• Sizing note added: reruns on every non-ASAN Electron lane, and the macOS persistence hazard (refuter enableRerun and macOS-hazard extra findings).
• Removed X06-D7 from blocked_by_keys: Linear owner for repo-writing Electron-compat slices (owner decision: align to nearest Linear issue, else GitHub is the tracker of record) #517 is CLOSED (gh, fetched 2026-10-07) with an adopted resolution; rule 4 forbids a closed decision as a blocker. Its resolution is consumed in linear_owner (GitHub tracker of record; KEL-81 Done so the reference falls back to KEL-127 Todo), and blocked_by_external now names the KEL-81 router as a task-level artifact (cross-checker finding: blocked_by names a closed decision).
• out_of_scope names X02-T6 as the product scoring run (cross-checker finding: X02-T6 is the flipping ticket).
