← Session 17 — Lean tier (i): elementary proofs (after crash)
thinking (245 chars)
Both documentation items done and committed. One more thing — the paper edit also fixed a stale line ("full lake rebuild deferred" → rebuild completed + live audit), which I should mention. Everything committed (03c1fc3). Done — confirm briefly.
Both items documented and committed (`03c1fc3`):
1. **11→8 divergence note** — now in three places:
- **D-057 §6** (new section at the source): rows #1–#4 vanish because the Lean theorem is parameterized over F (hψ hypothesis); the closed-form Ĉ₀/Ĥ terms produce exactly 8 block types; B̃₄ non-concavity → excluded from ψ-machinery, bounded directly
- **D-061 §5** update and **journal-011** design note
2. **E-029 upgrade in the paper** — the Formal verification appendix now presents it as the worked measured-to-traced example: grid-measured max `2n·|B̃₄″| = 0.189` on [20, 10⁴] superseded by the analytic factor-monotonicity proof `ψ̃″(s) − ψ̃′(s)/s ≤ 1.316 < 2` (`iimaj_bracket_bound`, `IIMaj_deriv2_lt`). The appendix section was also updated for tier (i) completion (and fixed the stale "lake rebuild deferred" line from before session 010's rebuild).
Paper compiles clean (12 pp). Git status clean. Everything is saved — have a good break.
