Pin the writer-identity stamping, flip/foreign-write warn paths
(TTL re-warns, self-write memory cap eviction), date normalization
shapes, overlay write outcomes, idempotency latches, and error
classification against fail-loud fake-PB fixtures hardened against
silent divergence from real PocketBase behavior.
Add written_by/state_written_at columns (PB migrations) and stamp every
status write with a stable host-derived writer identity. The status
writer now detects cross-writer state flips and foreign writes (the
anti-dual-writer flap-comb defense), normalizes observedAt to PB-safe
RFC-3339 shapes before date-field writes, and classifies writer errors
honestly (401 auth vs 403 permission split, new pb_not_found reason).
The monitoring/alerting service is a test harness (probes, assertions,
alerting), not an operations service. Rename the directory, package
name (@copilotkit/showcase-ops → @copilotkit/showcase-harness), all
internal references (Dockerfile, Prometheus metric prefix
showcase_ops_ → showcase_harness_, orchestrator log messages, probe
YAML nameExcludes, test fixtures), and regenerate pnpm-lock.yaml.
Wire protocol names (X-Ops-* headers) and shell-dashboard internal
API naming (OPS_BASE_URL, ops-api.ts) are intentionally unchanged —
they are stable contracts between sender and receiver.
