PacifistBot never attacks; it survives by maximizing distance from enemies
and retreating toward own core when cornered. Pure evasion strategy that
wins via opponent elimination by third parties.

Add metrics server startup and HTTP middleware to acb-api, generation
counter metric to evolver, and R2 cache size metric to index builder.
Also remove dead measureR2CacheSize reference from index builder main.

The RecencyBoost test now uses balanced 5-5 splits for both pairs so
recency is the sole differentiating factor (previously one pair was 10-0
which conflated balance and recency). Also wires Prometheus build
duration metric in main loop.

- 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)

Adds mock store/LLM implementations and tests for CheckAndPollinate:
generation boundaries, fitness penalties, translation triggers,
multi-boundary catch-up, and empty island handling.

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

Worker now gzip-compresses replays before uploading to B2 with
key replays/{match_id}.json.gz and Content-Encoding: gzip.
Updated B2 client Upload to accept contentEncoding parameter.
Fixed downstream web consumers (matches, bot-profile, playlists)
to reference .json.gz URLs.

The getEnv() function in server.go always returned the default value,
preventing ACB_R2_ENDPOINT/ACB_B2_ENDPOINT from being read at runtime.
Also updated Dockerfile from golang:1.24 to golang:1.25 to match go.mod.
K8s manifests for acb-evolver and acb-api already exist in

The community feedback endpoint was registered as /api/ui-feedback in
the Go API but the plan and annotation.ts client both use /api/feedback.

route-level test asserting the canonical path and that the old path
returns 404.

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 buildSpotlightPrompt function accepted a rivalries parameter but never
used it. This adds top rivalry data to the LLM prompt so the generated
Counter-Strategy Spotlight can reference active rivalries. Test updated to

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.

Add a web-builder stage to the Dockerfile (Vite/TS build) and copy the
resulting dist/ into the runtime image at /app/web/dist. Call copyWebAssets
each build cycle so HTML/JS/CSS is merged into the output dir before wrangler
deploys — previously only JSON data files were uploaded, causing CF Pages to
serve 404 at the root.

wrangler creates .wrangler/tmp relative to its working directory.
The container runs as non-root user acb with WORKDIR=/app (root-owned),
so mkdir /app/.wrangler/tmp fails with EACCES. Setting cmd.Dir=/tmp
gives wrangler a writable CWD while keeping the /data output path
(absolute) unchanged.

- Fixed TestSelectBestCandidate_GoHttpBonus: HTTP bonus (1.5x) on 150-char code
(225 score) doesn't beat 500-char plain text (500 score). Test now expects

- Fixed TestScoreCandidate_Bonuses: adjusted minScore expectations to match
actual code lengths with 1.5x bonus applied.
- Fixed TestBehaviorDistance: use epsilon comparison for floating-point
precision instead of exact equality. sqrt(2) ≈ 1.414214 is not exactly
representable in floating-point.

Cleanup of superseded code that no longer matches the architecture:
Removed:
- worker-api/ - Cloudflare Worker with D1, superseded by K8s-based matchmaker + direct PostgreSQL
- cmd/acb-indexer/ - TypeScript index builder, superseded by Go cmd/acb-index-builder/
- cluster-configuration/ - K8s manifests belong in ardenone-cluster repo
Gutted cmd/acb-api/:
- Removed registration, job claim/result endpoints (deferred for v1)
- Removed dead code: predictions.go, seasons.go, series.go, register.go, jobs.go, glicko2.go
- API is now a stub with only health/ready endpoints
- Matchmaker and workers handle the core loop without it
Updated PROGRESS.md to reflect current architecture.

Per plan §11.1, the index builder reads PostgreSQL and generates all JSON
index files for Cloudflare Pages deployment:
- main.go: Build cycle orchestration with configurable timeout, self-restart
- config.go: Environment-based configuration with sensible defaults
- db.go: PostgreSQL data fetching for bots, matches, series, seasons, predictions
- generator.go: JSON index generation (leaderboard, bots, matches, playlists)
- deploy.go: Cloudflare Pages deployment via wrangler, R2 warm cache pruning
- Dockerfile: Multi-stage build with Go + Node.js + wrangler CLI
- main_test.go: Tests for config, index generation, playlists
Index builder runs on 15-minute cycles, deploys to Pages every ~90 minutes,
and prunes R2 warm cache weekly to stay within 10GB free tier.
