Fresh-session safe. 197 commits; six waves (bank rates 67/79/69/68/73/60%);
cookbook 508 sections with all six idiom harvests banked (§162-§167).

Resume order: T5/phase close is a LIVE option (the >=95% instr milestone is met
and holding); otherwise wave 7 from tools/wave/crack_wave.js after a regen.

§167's saturation signal is the strategic finding: COVERED+UNSOUND went
57% -> 64% -> 76% across three harvests, five new laws from 197 claims. Stop
mining waves for idioms; spend the tokens on cracks.

Carries the session's central lesson: four times a tool asserted a conclusion it
never reached, and I repeated the pattern once myself. A confident wrong label
costs more than a missing one.

+
+## ▶ RESUME HERE — READ THIS BLOCK FIRST
+1. **T5 / phase close is a LIVE OPTION.** The milestone reads *"≥95% instr fleet, OR every remaining
+   overlay stub on a named ledger"* — the first branch is met and holding at 95.1%.
+2. **If continuing: wave 7 = the next 40 by templatable weight.** Harness is
+   `tools/wave/crack_wave.js` (in-repo, contracts in its README). REGEN FIRST
+   (`make sig-overlays && make sig-modules && tools/family_hseq.py`), derive by
+   `members × nins`, pass `{wave:"wave7"}`, size-route Haiku ≤30 / Sonnet ≤120 / Opus above.
+   **Bank rate is measured six times: 67 → 79 → 69 → 68 → 73 → 60%.** Budget on ~65-70%.
+3. **STOP MINING WAVES FOR IDIOMS (§167's saturation signal).** COVERED+UNSOUND went
+   57% → 64% → **76%**; five genuinely new laws out of 197 claims. Harvest only what a skeptic
+   grades **byte-probed**, and spend the tokens on cracks instead.
+4. **The frontier:** 1,817 zero-crack families / 6,029 members / 246,221 ins · **4,513 singletons /
+   277,836 ins** (now the LARGEST pool — the roadmap's predicted endgame grind) · 233 partially-
+   matched families / 1,201 open. **The ×16 was the last of its kind; 91% of families are ×2-×4.**
+5. **Open, named:** `func_8017C294` (×16, 3,936 ins) NEAR at **2 ins** after four seeded attempts —
+   the board's biggest single item · the §154-A module leading-island wall (44 jr slots, design in
+   `jtbl_carve.migrated_tables`) · `gate_stage` still has **no revert guarantee for an exception
+   raised outside its stage loop** (that is what stranded drafts in `src/` and made 17 re-gates read
+   0/17 — port `jtbl_family_bank._bank`'s wrapper).
+
+## 🔑 THE ONE THING TO CARRY FORWARD
+**Four times this session a tool asserted a conclusion it had never reached**, and each cost real
+work: the `no-diagnostic` classifier · the poisoned-tree `0/17` · the dead-verifier `refuted: 22` ·
+`gate_stage`'s `(declaration/TU plumbing)`, which aimed five waves of agents at codegen for a body
+that was byte-correct from its first draft. **I then did it myself** — relayed that agent's causal
+story to Drew without checking it, and had to strike it from §166a (R14). **In this project a
+confident WRONG label costs more than a missing one**, because it redirects every later attempt away
+from the real fault. Prefer **"CAUSE NOT DETERMINED" + the next check to run.**
