Scout report: merge-ready - LIGHT re-review (Carl): prior blocker fix verified — chart partial keeps nil averages nil (zero-width bar + em-dash, 2%-floor only for real values) with a regression test; model/conductor layer byte-identical since prior approval; cert tree d62d614a matches branch head tree; CI 4/4 green including test lane. Reporter: carl Outcome: merge-ready Findings: - Blocker fix present+tested: _deployment_average_chart.html.erb no longer coerces nil via .to_i; release_duration_label(nil) renders em-dash; regression test asserts width:0% + no false 2% bar - Delta since prior review is exactly 2 files (chart partial + helper test); release.rb, bin/release.rb, migration, controllers untouched — no regression in the approved model/conductor layer - Non-defect verified: partial coerces max_seconds via .to_f internally, so pct math is float division despite integer chart_max at call site - Nit (non-blocking): new ERB comment contains % chars (2%-floor) inside <%# %> body — parses fine (no %> sequence) and suite is green, but house comment rules discourage it Questions: - none Checks: - git diff 5c6d5296..82e107d4 --stat = chart partial + application_helper_test only - branch head tree d62d614a6aa5... == claimed cert fingerprint (tree equality, not stale) - gh pr checks 453: lint, scan_js, scan_ruby, test all pass at head 82e107d4

Scout report: merge-ready - Deep review PASS: one pricing SoT (lib/usage_pricing.rb), both callers delegate, rates verified against the claude-api reference, gates green Reporter: carl Outcome: merge-ready Findings: - Pricing math exact: opus-4-8 5/25 per MTok, cache-read 0.10x, cache-write 2.0x (1h list tier); [1m] strip correct — no long-context premium on this roster - Cache-write 1.25x->2.0x is the deliberate correction; downstream test expectations updated with math comments (task_cli, atomic_event_cli, agent_session_usage) - Non-blocker: flat 2.0x write multiplier (no per-TTL split) — capture stores one flattened cache_creation bucket; per-TTL named as later phase in module comment - Non-blocker: dor-check from primary checkout false-flags cert STALE (fingerprints wrong tree); PASSES from worktree; tree equality verified (ad5a8571 == PR head tree) Questions: - none Checks: - dor-check PASS (worktree): full-suite + rubocop certified at ad5a8571e907, CI green 4 checks - standalone unit run: ruby -Itest test/lib/usage_pricing_test.rb — 12 runs 0 failures (plain-Ruby claim holds) - no same-file overlap with open PRs 452/453/454; base=release, ready (not draft), mergeable

Scout report: merge-ready - Deep backend review: single UsagePricing SoT verified against authoritative Anthropic pricing reference (all model rates + 0.10x read / 2.0x 1h-write tiers correct); both delegations preserve contracts; nil/unknown model prices to nil never $0; BigDecimal 4dp matches decimal(10,4) cost columns; dor-check PASSES on PR tree (primary-checkout STALE was the known tree-fingerprint false positive - cert ad5a8571 == PR head tree); CI green; no orphaned refs to removed constants; no cross-PR file overlap. Reporter: carl Outcome: merge-ready Findings: - Non-blocker: per-action path still folds cache writes into tokens_in at 1x (cost_for hardcodes cache_creation:0), so per-action rows under-price writes vs per-activity/task rows; documented as Phase 2 and the parity test scopes itself to cache_creation=0. - Nit: gpt-5.5 entry lacks cache_creation override - a nonzero cache_creation bucket would price at 2.0x input though OpenAI does not charge for cache writes; dormant since Codex capture sets cache_creation=0. - Nit: UsagePricing.rates re-parses ATOMIC_ACTION_MODEL_RATES JSON on every price call when env set (deliberate un-memoization for test freshness; trivial cost). Questions: - none Checks: - gh pr view 455: OPEN, not draft, base release, MERGEABLE/CLEAN, CI 4/4 green - cert tree ad5a8571e907... == git rev-parse origin/feat/unified-usage-pricing-module^{tree} (exact match) - bin/dor-check from PR-head worktree: DoR-to-Merge met (unit+integration tiers, cert, CI) - git grep: zero remaining references to MODEL_RATES/PRICING/rate_for/multiplier constants outside module+test - rate table + cache multipliers verified against claude-api skill pricing reference (2026-06-24 cache)

Scout report: merge-ready - Backend light read clean: reversible nullable tested_at migration, best-effort conductor stamp bracket, nil-safe span math, honest legacy-row handling Reporter: carl Outcome: merge-ready Findings: - deployment_span handles all stamp states: legacy shipped rows w/o tested_at read missing/em-dash and drop out of averages via filter_map (per-stage sample_count honest) - Tracker safe: RELEASE_TRACKER_STAGES is name-keyed, tested inserts into STAGES without adding a node; dev advance toy skips it - record_release_event rescues SystemExit+StandardError so a board outage cannot abort prepare; tested not in STAGES_THAT_MAY_OPEN so no ghost RC - Non-blocker: reopen! keeps tested_at (first-write-wins), so a re-prepared RC keeps the first test run's Tested span — consistent with kept testing/assembling starts - Non-blocker: releases/show Stage Averages still reads legacy DurationCache; detail page can disagree with new table until migrated Questions: - none Checks: - gh pr view 453: OPEN, not draft, base release, CI green (test/lint/scans) - e2e Release Steps heading matches current origin/release

Scout report: merge-ready - Deep review clean: protocol object + admin-gated controller/view/routes match all 6 acceptance criteria; ran bin/release-check fresh at PR head 17571dc (green); red mcritchie consumer CI verified as exactly the operator-excepted agent-worktree flake (repo-missing on runner), unrelated to this diff; turf consumer green Reporter: carl Outcome: merge-ready Findings: - dor-check red-CI flag is solely the excepted consumer flake (1 failure in 3082 runs, env-gap not diff-related) - advisory non-blocking: record.as_json dumps all attributes (filter_attributes does not apply) — suggest v2 except:/only: registration option before registering secret-bearing models - merge-safety note: PR 11 (docs refresh) also edits CHANGELOG Unreleased region — second-to-merge needs trivial rebase - nit: version bumped 0.12.0 in-PR while CHANGELOG entry sits under Unreleased — stamp dated header at gem publish Questions: - none Checks: - [full-suite] bin/release-check rerun by reviewer in worktree at 17571dc — green - [consumer-ci] mcritchie job log inspected: only AgentWorktreeTest#test_mcritchie_config_reserves_3020 fails (repo missing on runner); turf green

Scout report: merge-ready - Backend/read-model lens: newest-unique read model is correct. Earliest-per-species (strict <) then max_by(at) across species; repeat spawns/evolutions provably never re-bump. UNION of SessionMascot + TaskEvent(mascot) complete; shiny subset filtered on both sources; nil/missing snapshots safe via WHERE + =='true'; empty sources return nil. Non-blocker: full-scans both tables into Ruby per page load (no JSONB index on task_events.metadata->mascot->slug). Reporter: carl Outcome: merge-ready Findings: - APPROVE - no correctness defects in app/models/pokemon_pokedex.rb - Non-blocker perf: newest_unique/_shiny load full SessionMascot+TaskEvent history into Ruby every render; evolution_appearances full-scans task_events via JSONB expr with no supporting index. Correct but O(all history)/request; consider SQL GROUP BY MIN + JSONB index if page sees traffic. - Trivial: 'mascot'=>pikachu.slug added to first unit test's task metadata is vestigial (new code never reads devops.mascot); assertion resolves via session_id/AgentAction path. Questions: - none Checks: - [unit] pokemon_pokedex_test covers first-seen-across-spawns+evolutions, never-re-bump (repeat spawn), shiny subset

Scout report: request-changes - Clean diff, correct pattern; blocked on gates: dor-check RED (full-suite/rubocop cert MISSING) + mcritchie consumer CI RED on unrelated AgentWorktreeTest flake leaves AC#6 unmet; base is main not release. Reporter: carl Outcome: request-changes Findings: - Code is correct and mirrors admin-models host-registry pattern (never constantizes host models by name); 5/6 acceptance met. - AC#6 'consumer CI green in mcritchie' UNMET — red is pre-existing AgentWorktreeTest#test_mcritchie_config_reserves_3020 harness flake (repo missing sibling mcritchie-studio), NOT caused by this diff; must be guarded consumer-side or excepted with sign-off. - dor-check RED: full-suite/rubocop cert MISSING for this SHA — run bin/full-suite-check or record a justified gem [full-suite-bypass]. - PR base is main; studio-engine release == main at SHA 1671e54 (zero drift) — re-point base to release. - NON-BLOCKING: register-in-initializer guidance (model_page.rb:19-21) will empty the class-level @registry on dev Zeitwerk reload — recommend to_prepare; integration test covers only route drawing, not admin-gating/404. Questions: - none Checks: - [unit] model_page_test.rb 10 green - [integration] model_page_routes_test.rb route-draw + random-before-:id green - [ci] turf_monster consumer suite PASS; mcritchie_studio consumer suite FAIL (unrelated AgentWorktreeTest flake)

Scout report: merge-ready - Primary review found no blockers; PR satisfies LLM logging acceptance and is ready for Avi to advance. Reporter: carl Outcome: merge-ready Findings: - blockers: none - non-blocker: Codex model can remain nil on long local transcripts when model metadata is outside the parsed tail; actions, activity pins, and token usage still persist. Questions: - none Checks: - DOR: bin/dor-check standardize-llm-logging passed; cert tree 4940b56 matches HEAD tree for 68f1c3e. - Focused tests passed: atomic_capture_hook, agent_api, install_agent_skills, atomic_event_cli. - GitHub CI green on PR #448: lint, scan_js, scan_ruby, test; mergeStateStatus CLEAN; no open PR or local worktree file overlaps.

Scout report: request-changes - Code is correct, well-tested, docs-current, backward-compatible for all 5 criteria; CI green and touched tests verified green. BUT the DoR gate (mine) does not pass: full-suite/rubocop evidence lines are malformed and unit/integration tier tags are absent. Fix is a fast re-cert, not code rework. Reporter: carl Outcome: request-changes Findings: - BLOCKER (gate): checks_run cert lines are '[full-suite] ... green at 6fa63a721915' / '[rubocop] ...' — the gate only recognizes '[full-suite@<fp>]' (full_suite_gate.rb EVIDENCE_RE l79); fingerprint isn't inside the brackets so it never parses. dor-check reports full-suite+rubocop MISSING even from the exact branch tree (6fa63a72...=tree). Re-run bin/full-suite-check standardize-llm-logging from the branch to stamp valid evidence. - BLOCKER (gate): backend shape requires [unit]+[integration] dor_tiers; checks_run has neither tag. Tests EXIST and pass, but add tier-tagged checks_run lines (--checks REPLACES, so include the full-suite/rubocop lines too). - NON-BLOCKER: outcome_for (bin/atomic-capture-hook ~l844) flags any String output containing 'Process exited with code N!=0' as ERROR — a successful Codex tool whose output echoes that phrase (e.g. a test runner) would false-flag error. Conservative, low-impact. Questions: - none Checks: - Ran touched test files from branch tree 6fa63a72: atomic_capture_hook_test 48 runs/0 failures (incl new Codex tests), atomic_event_cli_test 53 runs/0 failures. Confirmed cert free-text fp == branch-head tree. - Verified Claude backward-compat: provider_for routes Claude events to unchanged path; turn_usage math identical for Claude payload shape; read_assistant_turn refactor is behavior-preserving.

Scout report: merge-ready - Carl light review found no blockers; approval wait state, board ranking, Local Demo action, and handoff docs align with acceptance. Reporter: carl Outcome: merge-ready Findings: - No blockers. Backend pass verified devops approval metadata is accepted by the API/CLI, waiting tasks sort ahead of stage peers, and the card pulse/button resolve when approval_status leaves waiting. Non-blocking merge-safety note: older open PR #363 also edits two docs modules, but PR #447 is clean against release. Questions: - none Checks: - Reviewed task metadata, PR body, changed files, docs, tests, GitHub checks, and merge safety; did not rerun gates per light SOP.

Scout report: merge-ready - Light backend review found no blockers; approval wait metadata, ordering, pulse, Local Demo action, and handoff docs match acceptance. Reporter: carl Outcome: merge-ready Findings: - No blockers. Same-file overlap with #438 CSS and #363 docs appears to be non-overlapping drift; PR #447 is mergeable against release. Questions: - none Checks: - Read AGENTS, README, Carl role, pr-review-light SOP, and task-board docs; inspected task JSON, PR body, changed files, diff, tests, CI, local /tasks 200, and open PR overlap; did not rerun gates.

Scout report: conductor-review - Code and local behavior read clean; PR is still draft, so Avi should resolve the readiness mismatch before final gate. Reporter: carl Outcome: conductor-review Findings: - Question: GitHub reports PR #447 isDraft=true while task is submitted; CI is green and mergeStateStatus is CLEAN. - Non-blocker: open PR overlap exists in docs (#363) and Tailwind CSS (#438), but #447 is currently one commit ahead of release, behind_by 0, and mergeable clean. Questions: - none Checks: - Reviewed required docs/SOP/Carl role, task metadata, PR body/diff/files, GitHub checks, local /tasks HTML, and open-PR overlap; did not run gates.

Scout report: merge-ready - Carl light read found no blockers; Pokedex now has Stats, Newest Pokemon, and Newest Shiny cards, with latest shiny derived from the canonical session mascot path. Reporter: carl Outcome: merge-ready Findings: - No blockers. Read-only controller/view change; no migrations or write paths. Backend query shape stays bounded, and release has advanced without touching Pokedex files; synthetic merge is conflict-free. Questions: - none Checks: - Inspected task metadata, PR body/diff, changed model/controller/view/tests, GitHub CI rollup, and merge safety. CI rollup is green for scan_ruby, scan_js, lint, and test at c0a7e400; git diff --check is clean.

Scout report: merge-ready - Primary review: acceptance, DOR, CI, and merge safety are green for PR #172. Reporter: carl Outcome: merge-ready Findings: - No blockers. NFL totals cache is transactional/idempotent for the 2026 baseline, uses existing game slug conventions, and the public totals page renders week data. - Non-blocker: open PR #169 also edits app/views/admin/hub.html.erb, but the hunks are separate and both PRs are clean against release. Questions: - none Checks: - DoR: /Users/alex/projects/mcritchie-studio/bin/dor-check team-totals-ui from the Turf worktree passed with tiers, full-suite/RuboCop cert, and CI green. - CI: gh pr checks 172 reports scan_ruby, scan_js, lint, test, and playwright (1-3) passing on 2590bfc. - Acceptance: localhost:3103 /up, /nfl/team-totals, and /nfl/team-totals?week=18 returned 200; CSV has weeks 1-18, 272 games, 544 team rows; Week 18 rendered 16 cards.

Scout report: merge-ready - No blockers in Carl backend light review; release-first ship, one-second member cadence, and Last Release glow match acceptance. Reporter: carl Outcome: merge-ready Findings: - Non-blocking coordination note: open PRs #434/#444 overlap helper/test release-board surfaces; PR #438 is GitHub merge-clean and does not overlap files already merged on release. Questions: - none Checks: - Read AGENTS, repo README/deployment/testing/devops docs, Carl role, task metadata, PR body, diff, changed files, CI, and merge safety; did not rerun review gates.

Scout report: merge-ready - No blockers found; countdown acceptance is covered and gates are green. Reporter: carl Outcome: merge-ready Findings: - Active tracker stages render countdown data from last-three shipped release stage spans; inactive stages keep ago/blank timing. - Current origin/release has advanced, but local merge-tree simulation reports no conflicts. Questions: - none Checks: - bin/dor-check release-stage-countdown passed: ui+db tiers, full-suite/rubocop cert, and GitHub CI green. - gh pr checks 434 passed scan_ruby, scan_js, lint, and test on b0c9e699. - Countdown-focused Rails tests passed: helper averages/overrun, broadcast payload, dev advance, and board collapse coverage. - curl http://localhost:3014/deployments shows data-mode=countdown with data-average-seconds and data-sample-count=3.

Scout report: request-changes - Primary review found a data-cache blocker: strict imports can partially write projections before raising. Reporter: carl Outcome: request-changes Findings: - Blocker: Nfl::CacheExpectedTeamTotals writes projection rows before strict missing-game validation raises; app/services/nfl/cache_expected_team_totals.rb:47-69 leaves partial cache rows committed on a bad later CSV row. - Non-blocker: PR is still draft; qa-release can undraft when ready, but review verdict is blocked on code. Questions: - none Checks: - DoR passed; GitHub CI green; targeted Rails tests green; 2026 cache rake task wrote 544 projections; transaction probe showed rows_after_error=2.

Scout report: merge-ready - Primary review finds the NFL team totals UI and cache implementation matches acceptance; DoR, CI, focused Rails, Playwright, live URL, and data cache repeatability checks are green. Reporter: carl Outcome: merge-ready Findings: - No blockers. Weekly cards render expected totals, all weeks 1-18 are available, and the importer reruns idempotently against the baseline dataset. - Non-blocker: PR #172 is still marked draft on GitHub, but the task merge gate and code review are green. Questions: - none Checks: - DoR merge gate passed from Turf worktree: full suite and rubocop certified fresh at c36b376895ea; GitHub CI green with 7 checks. - Focused Rails tests passed: 9 runs, 40 assertions, 0 failures. - Playwright e2e/nfl_team_totals.spec.js passed against http://127.0.0.1:3103. - Data proof: nfl:expected_team_totals_cache YEAR=2026 cached 272 games, 544 team rows, 0 stale deleted.

Scout report: request-changes - Code matches countdown acceptance, but the merge gate is not satisfied. Reporter: carl Outcome: request-changes Findings: - BLOCKER: bin/dor-check release-stage-countdown fails because checks_run lacks [unit], [component], [integration], [e2e], [full-suite@...], and [rubocop@...] task evidence. - MERGE SAFETY: sibling PR #438 conflicts with this PR in e2e/release_ship.spec.js and still asserts the old ago-mode tracker. Questions: - none Checks: - CI green on PR #434: scan_ruby, scan_js, lint, and test passed. - Focused Rails review tests passed locally: 186 runs, 1208 assertions, 0 failures. - Focused e2e passed on clean seeded port 3098: E2E_PORT=3098 npx playwright test e2e/release_ship.spec.js. - Acceptance read: active step renders data-mode=countdown with average payload; overrun flips negative; inactive steps keep existing ago/blank behavior.

Scout report: merge-ready - Carl light review found no blocking backend issues; Pokedex now has stats, newest Pokemon, and newest shiny cards while preserving the read-only controller surface. Reporter: carl Outcome: merge-ready Findings: - No blockers: latest_shiny_spawn is wired through PokemonController and the shared spawn card partial, with model and controller coverage for shiny and empty states. - Non-blocker: the existing task fallback remains session-first rather than globally timestamp-sorted across SessionMascot and task metadata; this PR preserves that inherited latest-spawn shape. Questions: - none Checks: - Read AGENTS.md, README.md, RUNBOOK.md, frontend/testing docs, Carl role checklist, and Avi pr-review-light SOP. - Reviewed PR #442 body, task metadata, diff, changed files, and local /pokedex response on localhost:3023. - GitHub CI for PR #442 is green: scan_ruby, scan_js, lint, and test; did not rerun review gates as light reviewer. - Merge safety: PR is clean against release and open PR file lists show no overlap with the Pokedex files.
