Changed RetirementCheckInterval from 1 hour to 24 hours to align
with the 7-day low-rating rule specified in §10.8. The retirement
automation is already fully implemented:
- startRetirementTicker: runs periodic checks (now daily)
- EnforcePolicy: retires bots below rating threshold (800) for 7
consecutive days, enforces 50-bot population cap
- queryConsecutiveLowRating: uses rating_history table to track
consecutive days below threshold
- RetireBot: handles K8s manifest deletion via declarative-config
- TestEnforcePolicy_CapEnforcement: integration test for cap enforcement

- Add ReplayPlayer to type imports in replay-viewer.ts
- Add explicit type annotation for entry parameter in replay.ts transcript map
- Fixes TypeScript compilation errors for §15.3 screen reader transcript feature
Implements the full map lifecycle audit as a hourly ticker in the
matchmaker:
1. updateMapFairnessStats: recompute per-slot win counts from completed
matches into the map_fairness table
2. flagUnfairMaps: flag maps where any slot deviates >10pp from expected
(1/N) across 80+ matches → status='probation'
3. retireDislikedMaps: force-retire maps with >20 net negative votes
4. pruneLowEngagementMaps: monthly bottom-10% engagement prune per tier
5. promoteClassicMaps: top-5 all-time engagement, 3+ months → 'classic'
Matchmaker already filters retired maps and gives probation maps 50%
reduced selection probability in selectMapLRU.

Adds generatePredictionsOpen to acb-index-builder, writing:
- data/predictions/open.json — upcoming predictable matches
Queries pending matches that are "predictable":
- Both bots in top 20
- Rivalry matches (3+ previous h2h matches)
- Series matches
- Evolved bot vs top-10 human-written bot
Output schema:
- updated_at — timestamp of generation
- matches — array of {match_id, bot_a, bot_b, a_rating, b_rating, open_until, head_to_head_record}
Limits to next 10 matches to keep file small. Refreshes every ~15 min by the index builder.

Add crane CLI to the runtime Dockerfile so the index builder can pull the
latest SPA shell from the Forgejo container registry on each cycle. The
existing syncSiteBuild logic checks for a newer image digest, extracts
the dist/ assets via crane export, and overlays generated JSON data files
on top before deploying to Cloudflare Pages.
- Dockerfile: install go-containerregistry crane binary (v0.20.2)
- sitebuild.go: new file with syncSiteBuild, craneDigest, craneExport,
digest caching, fallback to baked-in /app/web/dist
- main.go: wire initCraneAuth at startup, replace hardcoded webDistDir
with syncSiteBuild call in runBuildCycle
- sitebuild_test.go: 18 tests for extractRegistry, digest caching,
fallback logic, crane auth config, and copyWebAssets overlay behavior

The bestCandidate function allowed game count to override pairing recency
when both candidates had non-zero LastPairedAt values. Per §6.1, pairing
recency must be the primary criterion with game count only breaking ties.
Also adds 10 tests covering: never-paired preference, oldest-pairing
preference, game count tiebreaking, Pareto distribution verification,
multi-opponent selection, and regression test for the priority inversion.

Per plan §10.8 (deployment pipeline) and §9.8 (Argo Workflows):
- Add waitForWorkflowCompletion() that polls Argo Workflow API
- Add getWorkflowStatus() to fetch workflow phase/status
- Update Promote() to wait for workflow completion before inserting bot record
- Update Promote() to wait for K8s deployment readiness (waitForDeployment)
- Update triggerArgoWorkflow() to return workflow name for polling
- Add acb-evolved-bot-deploy-workflowtemplate.yml to manifests
The promotion flow now:
1. Writes bot source to bots/evolved/<bot_name>/
2. Commits and pushes source to git
3. Triggers Argo WorkflowTemplate
4. Waits for workflow completion (build + manifest commit)
5. Waits for K8s deployment to be ready
6. Inserts bot record into bots table
7. Updates programs table with bot_id/bot_name
This ensures evolved bots have running containers before being marked active.
Adds generateMapsIndex to acb-index-builder, writing:
- maps/index.json — active/probation/classic maps grouped by player count
- maps/{map_id}.json — full map definition with walls, cores, energy_nodes
Queries maps.map_json column for geometry; adds RawJSON field to MapData
and updates fetchMaps to select it.

Implementation complete:
1. engine/thumbnail.go - New thumbnail rendering package
- GenerateMatchThumbnail() creates 640x360 PNG thumbnails
- Renders grid, bots, cores, walls, energy with player colors
- SelectThumbnailTurn() chooses most interesting turn
- Pure Go stdlib image rendering (no canvas required)
2. cmd/acb-worker - Upload thumbnails to B2 alongside replays
- uploadThumbnail() generates PNG and uploads to B2
- Key: thumbnails/{match_id}.png, content-type: image/png
- Called after match completion, non-blocking on failure
3. cmd/acb-index-builder/deploy.go - Promote thumbnails to R2
- promoteRecentReplays() copies both replays AND thumbnails from B2 to R2
- Thumbnails promoted to warm cache alongside replay promotion
4. cmd/acb-index-builder/generator.go - Populate thumbnail URLs
- buildPlaylistMatch() now includes thumbnail_url field
- URL pattern: https://r2.aicodebattle.com/thumbnails/{match_id}.png
- Enables playlist cards and embed OG tags to show preview images

Replace random 2-player pairing with the full §6.1 algorithm:
- Seed selection: bot with oldest last-match timestamp (tiebreak: lowest bot ID)
- Format selection: seed's least-played player count among {2, 3, 4, 6}
- Opponent selection: Pareto 80%/16-rank skill proximity + oldest last-pairing
with seed + fewest 24h games for game-count balance
- Map selection: least-recently-used active map for the chosen player count,
with map_scores.last_used_at updated after each match
- Random player slot assignment for all participant counts

- Add Exploration and Formation axis definitions with feature extraction
from source code pattern matching (exploration/formation indicators)
- Extend Grid key from (x,y) to (x,y,z,w) with 3⁴=81-cell behavior grid
- Update bin assignment, promotion gate, and persistence (JSON snapshot)
- Add Slice() for 2-D dashboard visualization across any axis pair
- Migration: old 2-D archives project at z=middle, w=middle
- Update cross-pollination to pad 2-element behavior vectors to 4
- Add Prometheus metrics to matchmaker (bot crashes, stale job count)
- Add rivalry detection to index builder (data/meta/rivalries.json)
- Web: batched bot list loading, leaderboard keyboard accessibility,
improved ARIA attributes on match/playlist cards

Add crash_strikes and cooldown_until columns to bots table. Worker
increments strikes on crash (cooldown at 3), resets on success.
Matchmaker excludes cooldown bots from pairing, series scheduling,
and championship brackets. Fix erroneous cooldown filter on series
table in finalizeCompletedSeries (column only exists on bots).
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
The crash cooldown system was already implemented across engine, worker,
and matchmaker. This adds comprehensive integration tests that verify:
- Single crash does not trigger cooldown
- Two crashes do not trigger cooldown
- Three consecutive crashes trigger 30-min cooldown
- Successful match resets strike counter
- Interleaved crash/success resets counter correctly
- Cooldown extends on repeated crashes while on cooldown
- Matchmaker eligibility query excludes bots on active cooldown
- Matchmaker eligibility query includes bots with expired cooldown
- Full end-to-end flow: 3 crashes → excluded → cooldown expires → re-pair
Tests use ACB_TEST_DATABASE_URL env var for PostgreSQL integration tests
and skip gracefully when not configured.

Adds cross-pollination logic that copies the top program from each island
to a random other island every 50 generations. When source and target
islands use different languages, the LLM translates the code. Generation
boundaries are tracked per-island to prevent duplicate events.
- New crosspoll package with boundary detection, migration, and LLM translation
- Added MaxGenerationByIsland DB query for generation counter tracking
- Integrated into RunEvolutionLoop with observability logging
- Tests for boundary logic, translation prompts, and target selection

Playlist curation per §10 is fully implemented in the index builder:
- generatePlaylists() writes /data/playlists/index.json and {slug}.json
- curateWeeklyHighlights() selects best-of-week by upsets, elite
clashes, marathon turns, and closest finishes (last 7 days)
- persistGeneratedPlaylists() upserts to playlists/playlist_matches DB tables
- /data/playlists/ stub files seeded for all 12 curated collections
Replay viewer improvements shipped alongside:
- WinProbPoint refactored from {p0,p1} to {probs: number[]} for N players
- renderWinProbSparkline draws one line per player with matching colors
- replay.ts updated to build probs[] from replay.win_prob arrays
- Dynamic legend generated from replay.players instead of hardcoded P0/P1
New annotation overlay component (§16.8):
- AnnotationOverlay: timeline track, per-turn list, canvas markers
- createAnnotationForm: type selector, author, body, localStorage + API
- ANNOTATION_OVERLAY_STYLES: self-contained CSS for the overlay
Evolver: add mutations_per_hour metric to Totals (live.json §14)
Types: consolidate evolution types into types.ts, re-export from api-types.ts

The series scheduler was scheduling games and creating series_games rows,
but never updated winner_id or incremented a_wins/b_wins when individual
matches completed. This left series in perpetual "active" state since
finalizeCompletedSeries checks win counts that were never incremented.
Add updateSeriesGameResults step that:
- Finds series_games with completed matches but NULL winner_id
- Updates winner_id from match_participants
- Increments a_wins or b_wins on the series table
Called as step 0 in tickSeriesScheduler, before finalization checks.

wrangler creates .wrangler/tmp relative to its working directory.
The container runs as non-root user acb with WORKDIR=/app (root-owned),
