Healthchecks Foundation

Use when building a dead-man's-switch heartbeat monitor or cron-watchdog service: grace-deadline state machines across simple/cron/OnCalendar schedules, alert_after partial-index polling, ping ingest transactions with run-ID duration matching, flip outboxes, DB token-bucket rate limiting with an S3 circuit breaker, inverted-prefix S3 pruning, SSRF-guarded egress, signed bounce ingestion, and uwsgi attach-daemon deployment.

healthchecks: Heartbeat Watchdog Foundation

Foundation contract

This is a cold, source-specific foundation, not an operational procedure. It is historical, revision-pinned evidence rather than timeless guidance. Current project source, tests, requirements, and runtime behavior outrank this projection and decide what ships.

Provenance and revision

Source record: healthchecks; portable upstream identity, license, coverage caveats, and retrieval history are preserved in the index.
Recorded revision: master@29b5ec251059034b79e0120e2ff0c3e35d7bd9f8.
Full provenance, coverage caveats, boundaries, and preserved evidence: references/index.md.

Topic map

Representative topics: Deadline engine; Signal intake; Scheduler workers; Outbox & fan-out; Integration transports; Accounts & abuse control; Statistics & retention; Deployment.
Scope and retrieval questions: references/index.md#use-this-for.
Complete capsule chooser: references/index.md#load-the-matching-source-dump.
Detailed grouped map: references/index.md#capsule-map.
Source limitations and portability boundaries: references/index.md#boundaries.

Retrieval

Open the index, choose one capsule matching the active question, and load only that capsule. Revalidate its cited source and revision before relying on it. Do not bulk-load the inventory, treat historical claims as current truth, or apply this foundation as a procedure.
