Append FINDING to EPIPHANIES.md. PR #213 + ndarray PR #110 demonstrated the dumb-bookkeeper pattern: ~90 seconds, Haiku, enumerate+match+append. Result is a grep-addressable index of every shipped artifact keyed by the prompt-file brief that birthed it. For every future "what did we ship about X" query the ledger replaces a full-codebase grep with a single line — ~25 tokens vs ~25M tokens. Seven orders of magnitude cheaper. https://claude.ai/code/session_01SbYsmmbPf9YQuYbHZN52Zh

Concrete three-pass recipe added to the cca2a skill:
Pass 1 — Haiku bookkeeper (~90 s, mechanical): enumerate prompt files,
match against git log, append one ledger line per pair.
Pass 2 — Opus meta-synthesizer (read-only inputs): annotate the "none"
rows from Pass 1 with superseded/open/stale classification.
Pass 3 — Main thread consumer (sub-second per query): grep the ledger
for every "what's open / shipped / about X" question.
Closes three token-waste channels simultaneously:
- cold-start (20-30 turns → 3-5 turns)
- find-code (~25M tokens → ~25 tokens, 10⁷×)
- ambient arc knowledge (30-50% → 0%)
First deployments:
- PR #213 (lance-graph, 41 prompts mapped, 90 s)
- PR #110 (ndarray, 25 prompts mapped, 90 s)
