* chore: implement phase 9 Invariant defended: H5/H7. The one question: can check report a pass over a window it did not prove? Check() is the I/O shell around the pure decide(). Single-step synthesizes the header and its own sentinel, so no mode flag reaches the pure layer. Log mode stops the recorder before the one full read. The header, not a definition re-resolved after the window closed, is the authority for what was paused when the window opened — it decides `skipped`, the drain set, and the transitionGrace max. The flock, not the pidfile, is the authority for whether a writer still exists. * chore: remove unix build tag * chore: implement phase 10 (#2788) * Wire watch/check subcommands to the gate library, with a table+JSON renderer and H6/H7 exit-code mapping.

* chore: implement phase 7 Invariant defended: H3. The one question: can a rule be called alive because it looked alive one poll ago? proveCoverage (grafana-alertcheck/internal/gate/coverage.go) is the pure coverage function: nine checks over one rule's polls — sentinel, from-bounds, heartbeat continuity, health error/nodata, liveness, in-window pause, rule absence, KeepLast. Liveness is absolute, never a delta. Cross-domain comparisons translate by each poll's own skew and widen boundary segments by its skew bound, fail-closed. * chore: enhance unit tests * chore: address code review comments * chore: implement phase 8 (#2786) * chore: implement phase 8 Invariant defended: H6/H7.

* chore: implement phase 6 Invariant defended: H2. The one question: can watch return success over a window that nothing is recording? Watch() records the first observation of each non-skipped rule, then detaches a child that polls at the cadence in the header. The parent returns only after the child reports ready on an inherited pipe, and writes the pidfile after that. A clean stop writes the sentinel; a hard error does not. * chore: add a unit test, remove build tags * chore: address code review comments * chore: implement phase 7 (#2785) * chore: implement phase 7 Invariant defended: H3.

The one question: can watch return success over a window that nothing is recording? Watch() records the first observation of each non-skipped rule, then detaches a child that polls at the cadence in the header.

The one question: can a rule be called alive because it looked alive one poll ago? proveCoverage (grafana-alertcheck/internal/gate/coverage.go) is the pure coverage function: nine checks over one rule's polls — sentinel, from-bounds, heartbeat continuity, health error/nodata, liveness, in-window pause, rule absence, KeepLast.

The one question: can a violation ever outrank an unobservable rule, or can a pass happen without Violations empty and err nil?

* chore: implement phase 1 Strict parsers for the state and ruler endpoints (H1), a Prometheus-style duration parser, and fixtures sliced from real Grafana 13.1.0 payloads covering every required/optional-field and must-error case, including the "Normal (NoData)"/"Normal (Error)" composite reason states found live in the current fleet capture (not in the original plan's vocabulary). * chore: apply code review comments * chore: implement phase 2 (#2780) * chore: implement phase 2 Fix retry-error conflation, measure full poll latency, and harden Source test doubles for concurrency. * chore: enhance unit tests * chore: address code review comments * chore: implement phase 3 (#2781) * chore: implement phase 3 Add Resolve() for alert name resolution (uid:/Title/Folder/Title/ Folder/Group/Title forms, UID collapse, no-match suggestions) and the grafana-alertcheck CLI's list subcommand, the first runnable piece of the gate.
