The pod was CrashLoopBackOff for 45 days because it was running an outdated
image without the LIMIT clause fixes added in June. Updated to the latest
image digest which includes:
- LIMIT on fetchSeriesGames query (ca48b60)
- LIMIT on fetchRecentMatchIds query (68b7864)
- O(n²) iteration fix in generateBotProfiles (7befe51)
- Other OOMKill prevention fixes
This should resolve the silent crash after web asset copy.
The fetchSeriesGames function was querying all games for a series without a limit.
With up to 1000 series being fetched, and potentially many games per series,
this could return an unbounded number of rows and cause OOMKill.
A typical series has 3-7 games (best-of-5 or best-of-7), so LIMIT 100 is
more than sufficient to handle edge cases while preventing memory exhaustion.
Fixes acb-index-builder CrashLoopBackOff caused by OOMKill after web asset copy.
The query in fetchRecentMatchIDs was fetching all completed matches from
the last 24 hours without a LIMIT clause. In a high-traffic environment
with thousands of matches per day, this would cause the pod to run out
of memory and be OOMKilled.
This fix adds LIMIT 5000 to cap the number of recent matches fetched,
preventing unbounded memory growth while still providing sufficient
data for warm asset bundling.
Fixes acb-index-builder CrashLoopBackOff (4713 restarts over 45 days).
The generateBotProfiles function had two nested loops that caused O(n²) memory usage:
- Iterating through all rating history entries (10,000) for each bot (10,000) = 100M iterations
- Iterating through all matches (1,000) for each bot (10,000) = 10M iterations
This caused acb-index-builder to run out of memory and get OOMKilled during the build cycle.
Fixed by pre-building lookup maps (O(n) build + O(1) lookup):
- historyMap[botID] -> []RatingHistoryEntry
- matchMap[botID] -> []MatchSummary
Reduces complexity from O(bots × matches) to O(matches + bots) for lookups.
Resolves acb-index-builder CrashLoopBackOff after 45 days of failure.
- Identified root cause: pod was running 45-day-old image without LIMIT fixes
- Found recent commits (79ca6c0, cdf133d, 4554bed) that added LIMIT clauses
- Triggered acb-build workflow to deploy fixes
- Workflow acb-build-manual-nv552 now building
- Waiting for deployment to verify CrashLoopBackOff is resolved
- Add LIMIT 10000 to fetchSeasonSnapshots (season_snapshots per season)
- Add LIMIT 500 to fetchChampionshipBracket (series per season bracket)
These queries were called in a loop for each season without LIMITs,
causing acb-index-builder to be OOMKilled with 512Mi memory limit.
Fixes OOMKill after web asset copy in build cycle.
The fetchOpenPredictions function had an unbounded query building a pair
frequency map for rivalry detection. With thousands of bots and matches,
this could return tens of thousands of rows and cause OOMKill.
- Add ORDER BY COUNT(*) DESC to prioritize most common pairings
- Add LIMIT 1000 - sufficient to detect rivalries (pairs with >= 3 matches)
This fixes the 45-day CrashLoopBackOff with 4700+ restarts.

- Add LIMIT 100 to island populations query (fetchEvolutionMeta)
- Add LIMIT 10000 to lineage programs query (fetchLineage)
These queries had no row limits, causing OOMKill when the programs table
grew large. The pod crashed silently after "Copied web assets" because
Go panics and OOMKills exit without logging to slog.
Fixes acb-index-builder CrashLoopBackOff (4700+ restarts, 45 days).
- Add LIMIT 1000 to fetchChampionshipBracket (was unbounded)
- Reduce fetchSeries from LIMIT 5000 to LIMIT 1000
- Reduce fetchLineage from LIMIT 50000 to LIMIT 10000
- Reduce fetchFeedback from LIMIT 5000 to LIMIT 1000
- Reduce fetchRatingHistory from LIMIT 10000 to LIMIT 5000
The acb-index-builder pod has been in CrashLoopBackOff with OOMKill
(exit code 137) for 45 days with 4713 restarts. These unbounded queries
were loading too much data into memory, causing the kernel to kill the
process before any logs could be written.
Co-Authored-By: Claude <noreply@anthropic.com>
Added LIMIT clauses to 4 unbounded queries that were causing
acb-index-builder to crash with OOMKill after copying web assets:
- fetchPredictorStats: LIMIT 100 (was loading all predictor stats)
- fetchMaps: LIMIT 500 (was loading all maps)
- fetchSeasonSnapshots: LIMIT 1000 (was loading all season snapshots)
- fetchSeasons: LIMIT 100 (was loading all seasons)
These queries had ORDER BY but no LIMIT, causing them to load
massive datasets into memory on each build cycle, leading to
container OOM after the web asset copy phase.
Fixes bead bf-2ws
- Add LIMIT 50000 to fetchLineage (evolution programs table)
- Add LIMIT 10000 to fetchBots
- Add LIMIT 5000 to fetchSeries
These queries had no bounds and could grow arbitrarily large,
causing acb-index-builder to OOM during build cycles.
The lineage table in particular grows unbounded with evolution.
Fixes CrashLoopBackOff that has persisted for 45 days.

Rebuilt leader-targeter-bot JAR with Maven after verifying
compilation. The bot implements multi-player score-aware
targeting strategy.
Co-Authored-By: Claude <noreply@anthropic.com>
Implement a new Java bot that applies multi-player game theory: in N>2
games, always direct all units toward the current score leader rather than
the nearest enemy. This creates a natural kingmaker dynamic that prevents
any single bot from running away with the game.
Strategy:
- Identify all visible opponents and their scores (cores count as proxy)
- Pick primary target: opponent with highest inferred score (tiebreak: nearest)
- Send all bots toward primary target's centroid (mean of visible bots + cores)
- Exception: if own core is under threat (enemy bot within 6 tiles), detach 2 bots to defend
- In 2-player games: fall back to straight aggressor strategy
Novelty: No current bot does multi-player score-aware target selection. Most
bots target nearest enemy, which lets a distant leader accumulate score
unmolested. Leader-targeter explicitly models the N-player problem.

Implement CoordinatorBot - a multi-role strategy bot that dynamically
allocates roles (Attacker/Harvester/Defender/Scout) each turn based on
game state.
Features:
- Per-turn role assignment using greedy Hungarian-style algorithm
- Dynamic role rebalancing based on threat level, economic pressure, score
- Zone-aware survival logic
- HTTP server with HMAC authentication
- TypeScript implementation with full type safety
Role allocation algorithm:
- Base split: 50% attackers, 25% harvesters, 15% defenders, 10% scouts
- Adjusts: +10% defenders if threat > 0.3
- Adjusts: +10% harvesters if energy < spawn threshold
- Adjusts: +20% attackers if score leads by 5+
- Assigns bots by proximity to role targets

Verified all 5 backlog items:
- Combat kill scoring (engine/turn.go:272-275)
- Fitness formula blending win rate + kill rate (run.go:608)
- CombatDeaths tracking through arena (arena.go:204-221)
- Behavior vector derived from actual kill rate (run.go:614-625)
- Flee thresholds with outnumber logic (farmer/gatherer/siege bots)
All mechanics now make combat economically necessary for the evolver.
All backlog items completed:
- Combat kill scoring in engine (turn.go:274)
- Fitness formula blends win rate + kill rate (run.go:608)
- Flee thresholds reduced with outnumber logic
- CombatDeaths tracked through arena MatchOutcome
- Aggression derived from actual kill rate in behavior vector
This Genesis bead tracked the full mechanics iteration to make combat
economically necessary and reward aggression in the evolver.
## Flee Threshold Changes
- Reduced flee threshold from AttackRadius2+4 to AttackRadius2 (no buffer)
- Modified bots: farmer, gatherer, siege
- Bots now only consider enemies in actual attack range, not preemptively
- Added outnumber logic: only flee when nearbyAllies < nearbyEnemies
## Behavior Vector Changes
- Derive aggression from actual kill rate (not self-reported)
- Formula: behaviorVec[0] = min(killRate, 1.0)
- Preserves existing economy value or defaults to 0.5
- Enhanced logging to show derived aggression value
## Rationale
Aggression must be economically necessary, not just rewarded.
Previous flee logic created a false safe option that discouraged combat.
Now bots only flee when actually outnumbered within combat range.
Related: bf-413 genesis bead tracking mechanics iteration
- Updated fitness formula: fitness = 0.7*win_rate + 0.3*kill_rate (was win_rate only)
- Added kill tracking to ArenaResult: TotalKills, TotalMatches, KillRate
- Updated evolver system prompt to explicitly mention combat kills are valuable
- Enhanced arena logging to show kill rate and total kills
This change makes the LLM evolver select for combat aggression, not just win
optimization. The system prompt now informs bots that kills and eliminations
are part of the fitness evaluation, encouraging more aggressive strategies.

Add 3 new hand-written bots to expand evolver seed pool:
- phalanx (Rust, alpha island) - formation combat with aggression=0.85, economy=0.1
- assassin (Rust, alpha island) - decapitation strategy with aggression=1.0, economy=0.0
- opportunist (Go, beta island) - conditional aggression with aggression=0.55, economy=0.55
This brings the total seed count from 6 to 9, providing richer starting
population across islands with diverse attack archetypes the evolver
can recombine.
Changes:
- Add seeds/phalanx_strategy.rs.txt, assassin_strategy.rs.txt, opportunist_strategy.go.txt
- Update seed.go with 3 new embed directives and seed entries
- Add TestSeedPopulation to verify 9 seeds insert correctly
- Update comments to reflect 9 seeds instead of 6

- Fixed contest_assignments to use bot positions as keys since bots only have position and owner (no ID field)
- Fixed tuple conversions for energy and walls to properly convert elements to int
- Added curl to Dockerfile for health check support
- Updated docker-compose.bots.yml for economist bot
Co-Authored-By: Claude <noreply@anthropic.com>
Adds bots/economist/bot.py and Dockerfile implementing a new strategy:
deliberately contest energy nodes that enemies are approaching to
destroy the contested energy, denying enemy income while harvesting
uncontested nodes for own economy.
Strategy priorities:
1. Maintain existing contest assignments (stay put)
2. Contest threatened nodes (intercept approaching enemies)
3. Reserve 1-2 bots to guard cores
4. Collect uncontested energy
5. Remaining bots explore toward map center
Pure collection mode when score lead ≥3 and turn > 200.

The ZoneDriver bot was fully implemented and committed in cdbc4c0.
This note documents the implementation and verifies acceptance criteria.
Co-Authored-By: Claude <noreply@anthropic.com>
ZoneDriver weaponizes the shrinking zone to force enemy eliminations:
- Computes zone boundary and identifies "kill band" (zone edge-2 to edge)
- Positions units to block enemy escape routes inward
- Herds enemies toward zone edge for passive eliminations
- Prioritizes survival for own bots near zone boundary
Novel approach: turns zone from map feature into active weapon.

- Add SiegeBot to engine/bot_strategies.go with spawn denial logic
- Implement standalone siege bot in bots/siege/ with main.go, strategy.go, Dockerfile
- Register siege bot in acb-local for arena testing
- Add test-siege-arena.sh script for validation
Strategy: Surround enemy cores to block spawning phase. Bot assigns
units to lockout rings (8 neighbors) around cores, greedily by distance.
Unassigned units collect energy or rush fully-sieged cores.
Tested: 3/10 wins vs rusher+gatherer, 1/10 wins vs rusher+gatherer+guardian
