Wire up the acb-map-evolver to run automatically on a weekly schedule
(Sunday 03:00 UTC by default) from the evolver deployment.
The map evolution ticker:
- Waits until the next scheduled time (weekday:hour:minute UTC)
- Runs acb-map-evolver --once to evolve maps for all player counts
- Repeats every 7 days
The schedule can be configured via ACB_MAP_EVOLUTION_SCHEDULE env var
(format: WEEKDAY:HH:MM, e.g., "0:03:00" for Sunday 03:00 UTC).
Enable via ACB_MAP_EVOLUTION_ENABLED=true or --enable-map-evolution flag.
Per plan §14.6: the weekly map evolution loads engagement scores,
runs MAP-Elites evolution, promotes high-scoring variants, and updates
the active map pool in the database.

- Implement runWeeklyLoop() function that waits for scheduled time and
runs evolution for all player counts (2, 3, 4, 6) weekly
- Add --weekly flag to enable weekly mode (default: Sunday 03:00 UTC)
- Add --weekly-schedule flag for custom schedule (WEEKDAY:HH:MM format)
- Add ACB_WEEKLY_SCHEDULE env var for configuration
feat(acb-evolver): add weekly map evolution ticker
- Add MapEvolutionEnabled and MapEvolutionSchedule to RunConfig
- Add --enable-map-evolution flag to acb-evolver run subcommand
- Add startMapEvolutionTicker() goroutine that runs weekly
- Ticker executes acb-map-evolver --once to trigger map breeding
- Configurable via ACB_MAP_EVOLUTION_ENABLED and ACB_MAP_EVOLUTION_SCHEDULE
This integrates map evolution into the bot evolver's deployment,
allowing weekly automated map evolution based on engagement scores
as specified in plan §14.6.

The --once mode was implemented but the command-line flag was not being
parsed. This commit adds the flag parsing and help text for --once, which
enables the weekly automated map evolution run from the evolver.
The evolver's weekly ticker (run.go) calls acb-map-evolver --once to
trigger map evolution on Sundays at 03:00 UTC as specified in plan §14.6.
Per plan §13.3, implements user-requested AI replay commentary with:
- HMAC bot authentication via shared_secret
- Rate limiting: 5 requests/day per bot
- Match validation (exists and completed)
- Idempotency via enrichment_requested_at column
- Enqueues to Valkey for acb-enrichment service
- Returns 202 Accepted with estimated wait time
Also adds:
- AllowN() method to ratelimit package for multi-token checks
- enrichment_requested_at column to matches table (idempotency)
- enrichLtr rate limiter (5/day per bot)

- Add 'featured' boolean column to series table for weekly featured series
- Add tickFeaturedSeries ticker that runs Friday 20:00 UTC to create bo5 featured series
- Featured series: query top 20 bots by rating, select 4 rivalry pairs by ELO proximity
- Best-of-7 championship bracket already implemented via createChampionshipBracket
- Add FeaturedSchedSecs config (default: 3600s check interval)

Update the map engagement scoring formula to match plan §14.6:
- score = win_prob_crossings * 3.0 + critical_moments * 2.0 +
resource_contest_turns * 1.5 + survival_turns * 0.5
New metrics computed from replay data:
- resource_contest_turns: turns where energy is contested by multiple players
- survival_turns: turns where all players have at least one bot alive
The old formula used map_coverage_pct, closeness, and turn_pct which
did not match the specification.

- Change filter from 'idea'/'mistake' to 'insight'/'idea' (mapping to 'hint'/'strategy' from plan §13.6)
- Increase upvote threshold from 3 to 10 for higher quality signals
- The evolver consumes community_hints.json for LLM prompt context
The rating recovery CLI mode (-mode=recalc-ratings) was using
glicko2Tau (0.5) instead of glicko2DefaultSigma (0.06) for the
default sigma value when resetting ratings. This caused the reset
sigma to be ~8x higher than the schema-defined default.
Added glicko2DefaultSigma constant (0.06) and updated ResetAllRatings
and recalcRatings to use it correctly.

Implements the rating recovery procedure specified in plan §12.3.
Running 'go run ./cmd/acb-worker -mode=recalc-ratings' will:
1. Reset all bot ratings to Glicko-2 defaults (mu=1500, phi=350, sigma=0.06)
2. Fetch all completed matches from the database in chronological order
3. Replay each match to recompute Glicko-2 ratings from scratch
4. Update the bots table with the recalculated ratings
This is needed for disaster recovery when ratings are corrupted or lost.
Database functions added:
- ResetAllRatings: resets all bot ratings to defaults
- GetAllCompletedMatches: fetches completed matches chronologically with participants
- UpdateAllRatings: bulk updates all bot ratings in a single transaction

Add sitemap.xml generation as a final pass in the index builder. The
sitemap covers all public pages: home, leaderboard, bots list, bot
profiles, matches list, featured replays, seasons, rivalries,
predictions, and docs.
- Add SiteURL config field (ACB_SITE_URL env var, defaults to
https://aicodebattle.com)
- Add generateSitemap() function with proper XML encoding
- Add SitemapURL and Sitemap types for XML marshaling
- Call generateSitemap() at the end of generateAllIndexes()
- Write sitemap.xml to output directory alongside leaderboard.json

- Add engine.CalculateMapEngagement() to compute map engagement scores from replay data (win_prob_crossings, critical_moments, map_coverage_pct, closeness, turn_pct)
- Add DBClient.UpdateMapEngagement() to update map engagement using rolling average
- Worker now calculates and writes map engagement scores after each match
- Add test to verify win_prob array is non-empty in produced replays
This implements the win probability Monte Carlo array storage in replay JSON
feature. The engine already called ComputeWinProbability() in MatchRunner.Run(),
so this commit adds the missing map engagement tracking.

Energy node placement now uses a tiered radius distribution: 30% in the
contested central zone (0.05-0.20 from center), 40% in the mid-zone
(0.20-0.40), and 30% in the home zone (0.40-0.60). Previously nodes were
placed uniformly at 0.20-0.70, letting bots farm their home quadrant
indefinitely without crossing the midline.
After cellular automata wall generation, a 3-wide corridor is carved from
each core straight to the map center, plus a 5x5 open arena at the center
tile. This creates lanes that funnel bots into contact — replicating the key
mechanic that drove frequent fights in the original AI Challenge Ants game,
where symmetric food spawning near the midfield forced both colonies to
expand outward and collide.

Adds combat_turns metric (distinct turns where ≥1 bot died from enemy
focus-fire, excluding self-collisions). Worker computes it after each
match; index builder sorts matches/index.json and the new most-combat
playlist descending by it, and bumps interest score for combat-heavy
matches so they surface in highlights.
Also switches homepage featured replay default view from influence to
standard so the actual bot-on-bot combat is visible.

TestThreeMonthAgeCheck used 89*24h as "3 months minus 1 day", but
89 calendar days == exactly 3 months on dates like May 1 (Feb+Mar+Apr=

return true instead of false. Replace with AddDate-relative anchors
so the test stays correct regardless of current date.

Two root causes prevented bots from making any moves:
1. SignRequest signing string included timestamp ({match_id}.{turn}.{timestamp}.{hash})
but all bots implement verifySignature without timestamp ({match_id}.{turn}.{hash}).
Fixed by dropping timestamp from the signing string; X-ACB-Timestamp header is still
sent for clock-skew checks but not in the HMAC.
2. The API stores bot secrets AES-GCM encrypted (184 hex chars) in the DB. The worker
was passing the ciphertext directly as the HMAC key, while bots use their plaintext
k8s secret (64 hex chars). Fixed by decrypting in the worker using ACB_ENCRYPTION_KEY.
Also tightens the home page winner filter to exclude winner_id="0" stalemates.

_worker.js static file approach fails — Cloudflare rejects it when uploaded
as a static asset. Instead, copy web/functions/ into the image and set
wrangler CWD to /app/web/ so it discovers functions/ and uploads the Pages
Functions bundle correctly on every deploy cycle.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Every index-builder deploy was overwriting the production Pages deployment
without functions (wrangler ran from /tmp, no functions/ dir visible).
Compiling functions/ to dist/_worker.js during the Docker web-builder stage
means the worker is always included in every Pages deploy, regardless of CWD.

AWS SDK Go v2 s3 v1.100.0 defaults to RequestChecksumCalculationWhenSupported,
which causes PutObject to send STREAMING-UNSIGNED-PAYLOAD-TRAILER — a chunked
transfer mode R2 doesn't support. Setting WhenRequired makes the SDK send a
standard signed payload instead, resolving the 403 SignatureDoesNotMatch.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Adds R2 (Cloudflare) as a direct upload target alongside B2 (cold archive).
When ACB_R2_* credentials are configured, the worker uploads replays and
thumbnails to R2 immediately after each match, bypassing the index-builder's
B2→R2 promotion cycle.
This is necessary because ARMOR's B2 app key is write-only; reads via the
direct S3 path return 403. The Cloudflare CDN read path (armor-hub-b2.ardenone.com)
is dead post-hub-decommission. Direct R2 upload ensures replays are available
without waiting for a working B2 read path.

EndpointResolverV2 with a custom static URI does not honor UsePathStyle —
the resolver provides the final endpoint and the SDK does not re-apply
path-style bucket addressing on top of it. This means the bucket name was
dropped from the request path even with UsePathStyle=true, sending PUTs
to /replays/... instead of /armor-apexalgo/replays/...
BaseEndpoint is the SDK's documented approach for S3-compatible custom
endpoints; it sets the base URL and then correctly applies path-style
addressing to produce /bucket/key URLs.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Two fixes:
1. Add UsePathStyle=true to B2 S3 client. Without it the SDK uses
virtual-hosted addressing, dropping the bucket name from the request
path. Uploads hit /replays/... instead of /armor-apexalgo/replays/...
causing NoSuchBucket errors on every replay/thumbnail PutObject.
2. Don't update crash_strikes for normal game endings (stalemate, turns).
In snake-style games every bot eventually crashes into a wall/snake —
that is the expected end condition, not an HTTP error. The old code
treated all Crashed[] entries from the engine as errors, causing all
6 bots to accumulate strikes after every single match and hitting the
30-min cooldown threshold after just 3 matches.

The replay_feedback table was missing its foreign key constraint to
matches(match_id). This happened because CREATE TABLE IF NOT EXISTS

Added an idempotent migration that checks for the constraint's existence
before adding it, ensuring it's safe to run on both fresh installs and
existing databases.

The BaseEndpoint approach with older aws-sdk-go-v2 causes
"Invalid region: region was not a valid DNS name" errors when
uploading to ARMOR's S3-compatible endpoint.
Switching to EndpointResolverV2 bypasses the SDK's endpoint
rule validation entirely, resolving the issue.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Fixes 'Invalid region: region was not a valid DNS name' error when
uploading replays to B2 via ARMOR proxy.
The error was caused by a known bug in aws-sdk-go-v2 v1.41.4 where
the endpoint resolver would validate the region as a DNS name even
when using a custom BaseEndpoint with UsePathStyle=true.
Upgraded SDK versions:
- github.com/aws/aws-sdk-go-v2 v1.41.4 -> v1.41.6
- github.com/aws/aws-sdk-go-v2/config v1.32.12 -> v1.32.16

The AWS SDK requires a valid AWS region name even when using custom
S3-compatible endpoints (ARMOR/B2). Using "auto" as the region causes
an error: "Invalid region: region was not a valid DNS name."
This fixes the replay upload pipeline which was failing with the
invalid region error. Replays should now upload successfully to B2
via the ARMOR proxy.
Related to ai-code-battle-o43: Replay viewer verification task.
Verification results:
1. ✅ /data/blog/index.json exists and has 1 post (meta-week-13-season-1)
2. ✅ Individual post pages load correctly at /blog/{slug}
3. ✅ Blog post JSON structure matches frontend expectations (content_md field)
4. ✅ Tags and filters implemented in UI (All, Meta Reports, Chronicles buttons)
5. ✅ Blog page builds successfully (blog-D4QMd11d.js included in build)
Current state: Blog infrastructure is fully implemented with:
- LLM-powered narrative generation (blog.go, narrative.go)
- Story arc detection (rise, fall, rivalry, upset, evolution milestones)
- Weekly meta report generation with ELO movers, strategy analysis
- Chronicles for story arcs (rivalry, upset, rise/fall, evolution)
- Tag-based filtering and search
Note: Current blog content is placeholder/template-based. Meaningful
match commentary will be generated when:
- ACB_LLM_BASE_URL and ACB_LLM_API_KEY are configured in index-builder
- Real match data exists in PostgreSQL database
- Story arcs are detected from rating history and match results
Remove custom endpoint resolver and use AWS SDK's standard approach
for S3-compatible endpoints:
- Use config.WithRegion("auto") for custom endpoints
- Set BaseEndpoint directly via s3.NewFromConfig options
- Add UsePathStyle for B2 compatibility
This fixes the 'Invalid region: region was not a valid DNS name' error
that was preventing replay uploads. The deployment manifest already
sets ACB_B2_REGION to empty string to avoid conflicts.

Passing time.Duration (int64 nanoseconds) as $2 in NOW() + $2 caused
PostgreSQL to interpret the nanosecond value as seconds, setting

resulting time.Time — pq encodes it as a proper timestamptz.
