## What this package is

Layered, orthogonal learning packages extracted from one operator's Coworld player-optimization work, so a fresh coding agent can load the right tier and benefit immediately. Produced with the `extract-learning-package` skill.

- **universal/** — full deduplicated, synthesized lesson set (895 lessons), tiers blended; source of truth for re-runs.
- **crewrift-specific/** (212) — only-true-with-crewrift social-deduction specifics. Carries **LOOP.md** and **performance/LOG.md**.
- **optimization-loop-specific/** (526) — the hypothesis-driven A/B optimization loop over a scripted Coworld policy (+ nightly data-science refit). Game-agnostic across Coworlds.
- **generic/** (188) — true for any software / coding-agent / research work.
- **null-tier.md** — cuts and the tier-split record (reviewed, not vanished).
- **LOOP.md** — the reconstructed optimization loop (15 steps, two eval substrates, two nested cadences).
- **performance/LOG.md** — crewborg trajectory (v16→v25 champion), first appendable entry.
- **review.html** — the self-contained review page used at each checkpoint; doubles as a human-browsable index.

## How it was built (provenance)

- **Sessions mined:** 449 on-topic coding-agent sessions (core 213 + bounded-broad 236), from a 1,490-session local transcript DB.
- **Files swept:** 279 on-topic file artifacts across the player-optimizer repos (read-only on the metta tree).
- **Consolidation:** ~6,094 atomic records → 3,130 deduped → 895 synthesized → tier-split (31 genuine splits).
- **Search roots swept:** `~/coding/personal_labs`, `player_labs`, `archive/cogames_playground`, `coworld-source-repos.crewrift-upload`, `coworlds/coworld-crewrift`, `players_checkouts`, `bitworld`, `personal_cogs`, `sandbox`; `~/.claude` skills+memory; read-only `~/coding/metta/agent-plugins/kitchensink`.
- **Verification:** orthogonal tiers (0 cross-tier dupes), complete partition, standalone-coherent (LLM-audited), tracer-gated on every file.

## Caveats for consumers

- ~374 session-derived lessons are flagged ⚠ _unverified_ — extracted from conversation, not yet confirmed against live code/docs. Treat as candidates.
- First upload; re-runnable as the corpus grows (universal/ is the baseline).

## Related work in this repo

A prior Coworld player-optimizer package exists at
`packages/coworld/templates/optimizers/202624/richard-higgins-crewrift-player-optimizer`
(Richard Higgins, PR #15653) — same crewrift topic and tier structure, from an earlier week.
That package predates this provenance-tracer system and carries no tracer; this package is an
independent extraction from a different operator's machine (jboggs). The two are siblings, not
derivations: no content was copied between them. Naming/layout conventions here were aligned to
his for consistency across the `optimizers/` collection (per-tier AGENTS.md+CLAUDE.md, handle-nested dir).

## Source provenance

Single-operator extraction (jboggs / James Boggs machine). All learnings trace to that machine's
coding-agent transcripts and repos; session-derived items are paraphrased past a privacy gate (no
secrets/tokens/raw proprietary code) and marked ⚠ unverified until human-confirmed.
