Session Ledger

The session opened with a regression-test sweep of oddkit 0.21.1 across all 11 tools. The sweep found three bugs: a naive oddkit_encode parser (deferred to another active session), a telemetry_public envelope that was missing server_time / assistant_text / debug (every other tool already emitted them), and an oddkit_catalog debug.generated_at field that returned the cached index build timestamp instead of the response time, producing up to 48-minute drift from server_time in the same envelope. The two envelope bugs were the scope of this session; the encode refactor was explicitly parked.

Two small fix PRs landed cleanly under the new release-validation-gate canon. PR #124 (fix(telemetry_public): add server_time + full envelope) and PR #125 (fix(catalog): debug.generated_at is response time) each cleared Cursor Bugbot completed/success and received independent Sonnet 4.6 validator GO verdicts on their feature branches. Both merged to main cleanly. The release chore (PR #128) backfilled the [Unreleased] CHANGELOG section with a 0.22.0 entry covering both fixes, bumped all six version locations to 0.22.0, and caught a pre-existing root package-lock.json drift (stuck at 0.18.0 since four releases prior) along the way.

The promotion is where the canon's strict reading surfaced a gap. Between orchestrator turns, the operator merged PR #127 — a promotion of the #124 and #125 code to prod — before the chore PR existed. The feature-branch validators had issued GO verdicts, but neither had performed the full P1.3.1 five-corroboration pattern that canon requires on promotion PRs (particularly ×3 consecutive independent smoke runs). This left the load-bearing code shipped on an under-corroborated promotion. Revert was disproportionate (the code was healthy), so the orchestrator used the next promotion PR — PR #129 for the 0.22.0 version bump — to dispatch a fresh Sonnet 4.6 validator with explicit 5-corroboration mandate including a retroactive live prod smoke of the already-shipped #124 and #125 behaviors. The validator confirmed both healthy on prod (telemetry_public full envelope, catalog generated_at == server_time with 0ms delta across three consecutive runs, index_built_at present and consistent). The retroactive smoke was load-bearing evidence, not ceremony: it produced five concrete observations against the running system that the PR #127 promotion had never received. PR #129 merged; prod went to 0.22.0; post-merge smoke confirmed the version flip and no envelope regressions.

Total elapsed from regression-sweep start to 0.22.0 post-merge verification: roughly two hours. Four validator dispatches + one follow-up smoke, all GO. Zero bugs caught by the validators this cycle — but the retroactive smoke on PR #127 was the load-bearing move. Without it, the canon's Rule 2 would have been silently violated on an under-documented promotion and the session would have closed with thin evidence on a hot surface.

D1 — Batch two orthogonal fixes into a single 0.22.0 release

Both fixes added envelope fields consumers can rely on; semver-pre-1.0 says MINOR. Batching respects Use Only What Hurts (one release, one CHANGELOG section, one promotion) and the fix severities did not justify finer-grained rollback. Precedent: PR #112's 0.17.0 release bundled two unrelated envelope-contract changes under the same MINOR bump. Alternative (two separate 0.22.0 / 0.23.0 releases) would have doubled the validator and promotion overhead for no rollback benefit.

D2 — Run the full release-validation-gate flow

First session after the canon landed. The three rules — Bugbot-wait on every merge, Sonnet 4.6 validator on every load-bearing promotion, canon wins over session artifacts — applied to every PR opened. Result: four validator dispatches, all GO; Bugbot completed on every PR before merge; zero ad-hoc shortcuts.

D3 — Close the PR #127 gap retroactively via the PR #129 validator rather than reverting

When the operator's out-of-sequence merge of PR #127 put under-corroborated load-bearing code on prod, three options existed:

1. Revert PR #127 and re-promote through a fresh validator dispatch
2. Open a separate validation-only PR to document the gap
3. Use the next scheduled promotion PR (#129) to dispatch a validator whose scope includes retroactive corroboration of the already-shipped behavior

Option 3 was chosen. Criteria for legitimacy (new pattern, documented here for future sessions):

• The already-shipped code must be verifiable against live prod with concrete evidence (not inferred from code review)
• The retroactive smoke must perform the full P1.3.1 pattern on the shipped surface, not a lighter touch
• The gap must be named in the subsequent promotion PR body, in the validator task brief, and in the closeout ledger (this one)
• The retroactive corroborations must pass — a FAIL would escalate to revert, not accept

All four criteria were met; retroactive closure was valid. If any had failed, revert would have been mandatory.

O1 — Orchestrator bash container egress rate-limited by Cloudflare mid-session

Direct HTTP POSTs from the bash container to oddkit.klappy.dev/mcp and branch-preview URLs returned 403/503 starting partway through the session, while MCP connector bindings (tool calls via oddkit_time, oddkit_catalog through the Claude MCP client) kept working unaffected. Managed Agent containers — different egress origin — reached both preview URLs and prod cleanly throughout. The failure mode looks like per-IP rate limiting at Cloudflare's edge against the specific egress allocated to the bash container, not an outage. The workaround in this session was total delegation of live HTTP smoke to Managed Agents; that delegation worked for every corroboration needed. This observation graduates to a Learning (L3) and a Constraint (C3) below.

O2 — Pre-existing drift on root package-lock.json (adequate — 2/2 quality)

The root package-lock.json had been stuck at 0.18.0 since the 0.18.0 release chore (four releases prior). The four visible version locations (package.json, workers/package.json, both lockfile root "version" fields, and the nested packages[""] entries) were kept in sync, but the root lockfile's own "version" quietly fell behind. The chore agent (PR #128) noticed during the 0.22.0 bump and corrected all six locations in one pass. No functional impact during the drift — the root lockfile tracks CLI dependencies unchanged since 0.18.0 — but the drift is a named signal that the Version Sync CI check may be missing a field. Future release chores should verify all six locations move together; the check can probably be strengthened.

O3 — User merged PR #127 between orchestrator turns, producing behavior-ahead-of-version state

The operator opened and merged PR #127 (promote main → prod, bringing #124 + #125 code changes to prod) between my turns, before the orchestrator had opened the chore PR for the version bump. The result was a mid-session state where prod was running 0.22.0-worthy code but reporting version 0.21.1. Not a defect — the fixes were already validated on main — but the sequencing was out-of-canonical-order (canon-ideal is chore PR merges before promotion PR). The canonical fix-forward sequence (PR #128 chore → PR #129 promotion) closed the state within ~20 minutes of the observation. The larger insight: out-of-sequence operator action is not a process failure; the process needs to tolerate it without requiring revert.

L1 — release-validation-gate canon works as intended when followed exactly

This session ran the entire gate end-to-end for the first time post-canon-landing. All three rules applied cleanly: Rule 1 (no merges with active reviews) held on PR #124, #125, #128, #129 — Bugbot completed/success on every one before merge. Rule 2 (independent fresh-context validator for load-bearing) fired four times (feature #124, feature #125, promotion #129, post-merge regression smoke) — all GO. Rule 3 (canon wins) had no conflicts to resolve. Cost: roughly 4–5 minutes of Managed Agent time per validator dispatch plus orchestration overhead; total session cost maybe 30 minutes in validator time across the cycle. Value: zero bugs caught this cycle by the validators — but the retroactive smoke on PR #127 was the load-bearing move, and without the canon framework this session would have closed with thin evidence on a hot surface. The canon's value this cycle was process discipline, not bug detection — which is exactly what tier-1 constraints are supposed to deliver.

L2 — Feature-branch validators are not a substitute for promotion-PR validators

Canon's strict reading: the validator must dispatch on the PROMOTION PR specifically, and must perform the full P1.3.1 five-corroboration pattern (bytes grep, multiple-shape live curl, canon citation, exhaustive behavioral sweep, ×3 consecutive independent smokes). My PR #124 and PR #125 feature-branch validators issued GO verdicts but did NOT perform the ×3 smoke step. The PR #129 promotion validator is what finally ran the full pattern. Two takeaways: (a) the ×3 smoke is the hardest corroboration to skip because it catches flakiness that single smokes miss, and this session's 5-corroboration run across three catalog calls demonstrated perfect stability; (b) canon does not prohibit feature-branch validator dispatch, but sessions should budget for a separate promotion-PR validator with the full pattern regardless. A feature-branch GO is evidence; it is not the gate.

L3 — Managed Agent containers bypass orchestrator-IP rate limiting

When bash container 503s on direct curl to Cloudflare Workers, delegate live smokes to Managed Agents. Their egress is a different origin and Cloudflare treats them as separate traffic. This is a durable workaround for the orchestrator-IP throttle pattern and was used for all five post-rate-limit smokes in this session — every one succeeded. Record for future sessions: if direct HTTP starts failing from the orchestrator container and MCP bindings keep working, the pattern is rate-limiting, not an outage; delegate to a Managed Agent rather than wait.

L4 — Version bump as a separate chore PR is the right release shape

PR #112's precedent is now confirmed by this session's PR #128: atomic version-bump diff is easy to Version-Sync-validate, Bugbot-reviews cleanly (no behavioral code to parse), decouples version cadence from fix cadence, and naturally handles the case where multiple feat PRs land between releases (one chore PR backfills them all). Counter-pattern (inlining version bump into a feat PR) would couple behavioral review with metadata review and complicate Bugbot's signal. Keep this pattern as canon-adjacent convention.

C1 — PR #126 (encode parser refactor) is off-limits

PR #126 (feat(encode): D5 stemmed set intersection + D9 cache removal (0.22.0)) is actively in another session's scope. This session must not touch it. The one touchpoint: PR #128's CHANGELOG does not mention #126's expected encode changes because they have not yet landed on main; when #126 ships, the CHANGELOG will need a supplementary entry.

C2 — release-validation-gate canon binds every future oddkit ship

Tier 1, E0008.3, status: active. Rule 1 (no merges with active reviews), Rule 2 (validator dispatch for load-bearing), Rule 3 (canon wins over session artifacts). This session establishes the practical shape of the gate; future sessions start from here. No exceptions — "this scope is small" is the named failure mode the canon exists to prevent.

C3 — Bash container egress may continue to be throttled

Plan future sessions assuming live smokes from the orchestrator container may fail mid-session. Default to Managed Agent delegation for any curl that must reach Cloudflare Workers directly.

H1 — Consider running the full P1.3.1 pattern on feat-branch validators

This session used feature-branch validators with a lighter pattern (single smoke, no ×3) and relied on the promotion validator for the full pattern. That created the retroactive-closure scenario when operator sequencing moved the promotion up. Running the full pattern on feat-branch validators would eliminate the scenario but slow feat-PR iteration. Tradeoff worth raising as a session-level practice question — not a canon amendment.

H2 — O-open P11: oddkit_gate mechanical enforcement of release-validation-gate

Canon §Mechanical Enforcement Roadmap specifies oddkit_gate should detect completion transitions mentioning merge/promote/ship, pull the GitHub Checks API, verify all check-runs completed, verify Bugbot dispositioning, and verify a validator session ID is referenced for load-bearing PRs — returning NOT_READY with specific unmet prerequisites otherwise. Remains unbuilt. Until P11 ships, orchestrator obligation is heavier (orchestrator must search canon, follow the rules, and document disposition manually). Recommend P11 prioritized after the P1.3.4 encode canon-parity sweep (already in user memory's recent updates).

H3 — Regression sweep open-items still unaddressed

Two items surfaced at session start, not yet closed:

• nonexistent_tool telemetry entries — 16 calls/24h as of the pre-session snapshot. Investigate consumer-label source; likely an unlabeled edge function or stale tool-name reference somewhere in the ecosystem.
• Catalog doc-count drift — preflight reports 499 docs, search reports 527, catalog reports 531. Three different counts across three tools reading the same index suggest inconsistency in how each counts or filters.

Park as tracking issues or re-investigate in a dedicated session.

H4 — Bug #3 (oddkit_encode parser) — deferred

Explicitly out of scope for this session per operator direction. Known-gap summary: parser drops Observation and Learning types (or did as of last audit — this session's encode produced 18 artifacts across D/O/L/C/H/E correctly, so the DOLCHEO batch-prefix path may be working), duplicates full input as content for certain paths, returns constant quality score, uses naive title truncation. Full refactor is in PR #126 / another session.

H5 — Version Sync CI may be missing a package-lock.json root field

The root lockfile's own "version" field drifted four releases before being noticed. If the Version Sync check is only comparing the four visible fields (two package.json + two nested packages[""]), it's missing the two root "version" fields in the lockfiles. Worth verifying and extending if confirmed.

Session DOLCHE encoded via oddkit_encode with governance_source: knowledge_base, governance_uri: klappy://canon/definitions/dolcheo-vocabulary. 18 artifacts returned (3 D / 3 O / 4 L / 3 C / 4 H / 1 E). Persisted to file (oddkit_encode does not persist) and folded into this ledger as the D / O / L / C / H sections above.
