2026-07-23 directive: instrument candidates-proposed-per-served-turn on
clean, post-reset traffic. Adds an additive-optional turn_count_baseline
manifest field (engine_state) stamping the turn_count at the last clean
reset of the discovery-candidate ledger, a pure compute_discovery_yield
function (teaching/discovery_yield.py), and a read-only `core teaching
discovery-yield` CLI surface. Fails closed (returns None / exits 1) when
no baseline has been stamped rather than fabricating a denominator.
scripts/ops/stamp_discovery_yield_baseline_20260723.py stamps the T11
reset epoch into the live store, mirroring reset_candidate_corpus_t11's
atomic generation-dir pattern. Dry-run verified against a throwaway copy
of the live store's gen-21703; not yet executed against the real store
(see PR body).
Weekly-audit 2026-07-22 closeout — T13 decision (3) CI gate + T11 execution.
- scripts/hooks/pre-push + install.sh: a core.hooksPath pre-push gate that runs
the smoke suite PLUS the warmed_session consistency lane pin — the T13
telemetry-consistency regression class that smoke does NOT cover. The full
~12k fast-lane stays async CI by design; the gate is deliberately targeted so
it blocks the regression class without gridlocking pushes. Fail-closed on
empty stdin; skips deletion-only pushes; emergency bypass git push --no-verify.
- scripts/ops/reset_candidate_corpus_t11_20260722.py: provenance record of the
T11 live-store reset. The 465 discovery candidates predated the #100
isolation fix and carried no per-record test/prod discriminator, so a surgical
quarantine was impossible; ruling was to clear (not asterisk). Executed as an
ADR-0219 atomic generation reset (empty candidate ledger, keep=1) — candidates
465 -> 0, turn_count 14990 and identity lineage preserved, tainted generations
GC'd. Data lives in gitignored engine_state/; this script is the audit trail.
- AGENTS.md: document the automated pre-push gate under the Local-First CI
Validation Protocol.
- weekly-audit ledger: T10 merged (#100), T11 ruled+executed, T13 (2) hedge-arm
ruling + (3) pre-push gate recorded.
[Verification]: smoke 180 passed (132.9s) + warmed_session lane 10 passed
(140.5s), exit 0 — worktree core-wt-infra @ base 9a428d84.
