← Session 6 — Recover crashed run; plan all-forks execution
thinking (1720 chars)
The user asks for a recommendation. Let me think about the state:
1. Uncommitted E-010 re-run (extended params) — appears to be a completed, valid extension. Should be kept, re-registered, committed.
2. Paper reorganization — benign housekeeping, commit it.
3. E-011 — ran but failed validation. Fork 2 mid-debugging. Need to debug.
Recommendation: preserve everything first (commit the good stuff), then debug E-011. Order:
1. Verify the E-010 re-run data is complete/valid (check JSON checks pass), then commit housekeeping + E-010 extension as a "session 004 checkpoint" commit.
2. Debug E-011: the likely culprit — check η_k accuracy. V1 fails at 14 digits even though dps=1000 — that suggests a formula/sign/convention bug, not just precision loss, OR mpmath zeta wrongness contaminating (they used flint for zeta; but Stieltjes via flint.acb.stieltjes, series arithmetic in mpmath). λ_1 matches to 14 digits — that's exactly the "mpmath returns ~16 digits" failure signature. Wait — caveats say zeta values via flint.arb. But λ_1 off at digit 14 suggests something in the pipeline only carries double precision. Possibly flint ball converted to mpmath via float() or str with limited digits. That's a concrete first check.
Actually per instructions: don't over-investigate now; give recommendation. Keep concise. Recommend: (a) commit the safe completed work now to protect against another kill; (b) debug E-011 starting with precision-plumbing audit (likely a float() truncation since λ_1 fails at exactly ~15 digits despite dps=1000); (c) then continue forks 3, 4; (d) end-protocol.
Ask for approval to proceed? The user asked "what do you recommend" — give recommendation and ask to proceed. Keep it short.
My recommendation, in order:
**1. Protect the good work first (crash-safety, §8.4).** Before any debugging, commit what's already valid so another kill loses nothing:
- Paper reorganization + Notes.txt links (pure housekeeping).
- The E-010 extended re-run — after a quick check that its JSON checks pass, re-register in research.db and commit.
**2. Then debug E-011.** The failure signature is telling: λ₁ is wrong at digit ~14–15 despite `dps=1000`. That is exactly the "53-bit double" signature, not a precision-budget shortfall. So before touching the math, audit the precision plumbing — most likely a `float()` / string-truncation when moving flint Arb balls into mpmath, or one code path still calling `mp.zeta` (known broken beyond ~16 digits in this env). If λ₁ is fixed by that, re-examine whether V2/V3 failures were downstream of the same bug before re-budgeting precision (0.45·n digits) for large n.
**3. Only after E-011 resolves** (pass, or documented obstruction → graveyard), continue the remaining forks (3.3 de Bruijn–Newman, T4 ξ′-analogue), then gather thoughts per the fork rule.
**4. Session-end protocol** for this orphaned Session 004 work once E-011 is settled: journal entry, db registration, checklist/ledger updates, commit.
Rationale for this order: E-011's bug looks like a cheap plumbing fix, and we shouldn't burn time re-deriving precision budgets until the cheap hypothesis is eliminated; and nothing should sit uncommitted while we spend compute on debugging.
Want me to start with step 1 (verify E-010 re-run + commit housekeeping), then move into the E-011 precision audit?
