Pull request overview
Adds/updates Delphi documentation capturing the 2026-07-17→18 overnight parity/poller work: a sequential warm-start behavior inventory/spec, a math-poller replacement design, and corresponding journal + plan status corrections.
Changes:
- Add
SEQUENTIAL_BITS_PORT_SPEC.mddocumenting Clojure cross-tick stateful behaviors and the Pythonclojure-legacyport plan. - Add
MATH_POLLER_DESIGN.mddescribing the Python poller service intended to replace the Clojure math container/poller (phase 1 + cutover plan). - Update the parity journal and discrepancy-fixes plan to reflect updated statuses and findings from the session.

…18 → 07-24 s5), quirks + divergence ledger ## What Documentation for the R1-parity goal (the standing goal that the Python math engine reproduces the legacy Clojure engine's results under replay), covering the overnight session of 2026-07-18: - `SEQUENTIAL_BITS_PORT_SPEC.md`: verified inventory of all 11 cross-tick stateful Clojure behaviors, plus the port design that became PRs A/B/D'/C/E. - `MATH_POLLER_DESIGN.md`: recon-verified inventory of the Clojure container's responsibilities, the phase-1 architecture for the Python math poller (the service that polls Postgres for new votes and runs math updates), and the cutover plan (shadow -> flip -> decommission). - Journal: full overnight session entry, including the in-conversation 67-vs-68/69 RETRACTION, the generator input-fidelity fix, the H-A/H-B experiment results (self-jitter floors, and the first cross-language gap measurement), the sequential-bits PRs A/B/D'/C/E, poller phase 1, and the golden-kit evaluation. - PLAN: D1/D3/Replay status rows updated; a stale ns-PASS "pending" entry corrected (it was resolved 2026-06-11). ## Extended across the R1-goal sessions of 2026-07-22 (sessions 1-4) and 2026-07-24 (session 5) - `GOAL_R1_PARITY.md` + `GOAL_STATE.md`: the standing autonomous goal (DONE criteria, method, session protocol) plus its live checkpoint. - `CLOJURE_QUIRKS.md`: the replicated-quirk ledger Q1-Q18. Session 5 adds quirk Q17 (k-means cluster-step distance ties resolve by Clojure's map iteration order) as PORTED, and quirk Q18 (uniqify merge-center exact-equality is value-dependent floating-point ulp luck) as CARVED out of certification, with real-vectorz evidence. - `divergences.json`: the divergence-fingerprint ledger with per-divergence diagnoses. Session-5 end state: 70 resolved + 11 carved-out (Q18), ZERO open. - Journal sessions 4-5: the moderation/restart ports, the restart-seam `from_dict` restore root-cause + fix, the Q17/Q18 fork resolution, the `pc-meta-02` battery-entry swap, and the certification battery at 20/20 MATCH on two consecutive passes — goal condition (1) met.
