Evolver writes live.json to R2 every cycle. Observatory page polls and
renders live feed + lineage tree + meta shift chart.
- Added ACB_R2_UPLOAD_ENABLED env var to enable automatic R2 upload during run loop
- CycleState tracks real-time evolution cycle status (generation, phase, candidate, validation, evaluation)
- Export() now includes cycle info when cycleState is provided
- runCycle() integrated with live observatory exports at each phase transition
- exportLiveQuiet() for mid-cycle status updates without verbose logging
- Fixed function signature mismatches for exportLiveQuiet calls

- 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 the 'evolve' subcommand that ties together the LLM prompt builder
and ensemble components:
- Load programs from target island
- Select parents via tournament selection
- Analyze optional replay files for strategic context
- Build meta description from current ladder state
- Assemble evolution prompt with all context
- Run LLM ensemble (fast tier + strong tier refinement)
- Output generated bot code
Usage: acb-evolver evolve -island alpha -lang go [-replay file.json] [-out file.go]

- Add R2 client module (cmd/acb-evolver/internal/live/r2.go) with
S3-compatible uploads to Cloudflare R2
- UploadLiveJSON() uploads evolution state to evolution/live.json
with Cache-Control: max-age=10 for near-real-time updates
- Add -r2 and -r2-only flags to live-export subcommand
- Add tests for R2 config validation and credential handling
- Update frontend to fetch live data from R2 URL instead of Pages

- arena/arena.go: 10-match mini-tournament running candidate as a local
subprocess against diverse live opponents sampled across the rating
distribution; AES-GCM secret decryption for opponent auth
- arena/psro.go: Nash equilibrium computation for the 1×K meta-game;
FictitiousPlayNash included for future K×K support
- arena/winrate.go: Wilson-score 95% CI for win-rate calculation; draws
counted as 0.5 wins
- arena/gate.go: two-part promotion gate — Nash value ≥ threshold AND
MAP-Elites niche fill or improvement; detailed reason strings
- promoter/promoter.go: full promotion pipeline — bot source + Dockerfile
+ K8s Secret/Deployment/Service manifests, docker build, git commit/push
(ArgoCD sync), kubectl readiness poll, bots-table INSERT, programs-table
update; RetireBot and EnforcePolicy (rating threshold + population cap 50)
- db/db.go: add bot_name / bot_secret migration columns
- db/programs.go: ListPromoted, SetBotNameAndSecret, UnsetPromoted,
GetByBotID, PromotedCount helpers for promotion/retirement lifecycle
- main.go: evaluate and retire subcommands wiring arena + gate + promoter;
remove unused island flag from evaluate
- arena/arena_test.go: 21 unit tests covering Nash, Wilson CI, Gate logic,
and selectDiverse opponent sampling
- promoter/promoter_test.go: tests for Dockerfiles, bot-ID/secret generation,
AES-GCM helpers, and K8s manifest templates
