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.

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 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.

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
- github.com/aws/aws-sdk-go-v2/service/s3 v1.97.2 -> v1.100.0
- github.com/aws/smithy-go v1.24.2 -> v1.25.1

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.
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
cooldown_until to year ~59066 instead of +30 minutes.
Fix: pre-compute time.Now().Add(CrashCooldownDuration) and pass the
resulting time.Time — pq encodes it as a proper timestamptz.

The seasons table was recreated with id BIGSERIAL (not season_id VARCHAR).
The ClaimJob query was still referencing s.season_id (stale column name).

Raw game scores (capture points) are tied in most matches since the
winner is determined by an energy/bots-alive tiebreaker. This caused
Glicko-2 delta=0, leaving rating_mu frozen at 1500 for all bots.
Now winner gets 1.0, non-winners 0.0, draws 0.5 — correct pairwise
win/loss signal for Glicko-2 convergence.

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

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 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).

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.

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.

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.

Adds a metrics HTTP server to acb-worker exposing Prometheus text format
at /metrics, plus /health and /ready K8s probe endpoints. Tracks counters
(matches, errors, jobs, replays, polls, heartbeats) and histograms
(match duration, replay upload duration, replay size). Instruments the
full worker execution flow. Fixes .gitignore binary patterns to use
root-anchored paths so cmd/ subdirectories aren't incorrectly excluded.
