Sweep found 3 ledger figures wrong (R² "5th decimal" claim, "10 probes" undercount, "+13/−0,+10/−0,+0/−0" audit figures) and replaced the append-only audit itself (zero-deletions → suffix check, both halves measured, the new check correctly flags this very PR). §10 = measurement standard + dipole vector-sum model incl. stranded-storm regime + corridor α + queue-and-bow + sunflower/spiral-ADI substrate.

+## 2026-08-12 — lance-graph #930 (MERGED) — #929 hygiene that became a review sweep, a product-lead program, and a replaced audit method
+
+- **Added.** `probes/weather-p1/COMET_TAIL_REPORT.md` **§10** (the product-lead program: §10.1 measurement standard · §10.2 the dipole **vector-sum model** with the **stranded-storm regime** via `v_rel = v_storm − v_env` · §10.3 corridor α · §10.4 queue-and-bow anchors · §10.5 sunflower-facet / spiral-ADI substrate · §10.6 roadmap · §10.7 worker model) + `.claude/plans/weather-w-probes-v1.md` (Sonnet worker briefs; §0 is a **verbatim-paste preamble** carrying the iron rules, the `fetch()`/t-guard/`wrap_deg`/`circular()` code, controls-FIRST with the VOID rule, and the **stranded-rescue** checkpoint protocol — per-storm `<name>.partial.jsonl` + resume-skip + `exec-runs/` heartbeat, so a killed worker resumes instead of re-fetching ~GBs). Board: INTEGRATION_PLANS prepend, STATUS_BOARD rows D-W5 / D-W2sA / D-W6 / D-W2sB / D-W7 / D-CT-F17 (all **Queued**), the #929 arc entry + LATEST_STATE, and the sweep entry below.
+- **Locked — three ledger figures corrected and one audit method replaced.** Detail in the entry immediately below (kept as its own record because the sweep is the reusable part, not the PR).
+- **Locked — a MIXED PR must correct its own description the moment it drifts.** #930 opened as "pure hygiene, the chain stops here" and was twice falsified by its own later commits. Both times the title and body were rewritten **proactively**, before a reviewer found them — the #927 lesson applied rather than re-learned. Consequence honoured here: a mixed PR owes an arc entry, so this one exists.
+- **Deferred.** Every W-probe (operator go-ahead pending). **CT-F17 additionally gated** on W6's result **and** an independent adversarial spec audit before any bar is committed. The ~30 older CodeRabbit findings on #920/#921 remain **UNVERIFIED** by deliberate choice, recorded rather than absorbed.
+- **Docs.** Report §5.13 + §6.1 carry dated correction notes; merged #929's PR body was patched post-merge for the same false relation (precedent: #922).
+- **Confidence.** High on everything measured (every figure re-derived from the committed JSONs or from `git` in this session); the W-probe designs are **specifications, not results** — nothing in this PR was run.

+**Status:** MERGED (`9da349ac`). Branch `claude/jirak-math-theorems-harvest-rfii13` → `main`. Zero Rust, zero product code — docs, plans, board.

 ## 2026-08-12 — open-review sweep of #920–#930 — three frozen figures corrected, and the append-only audit replaced with one that can actually fail
 
 - **Scope, stated at the coverage actually achieved.** Operator asked for the open comments on #930, then the previous five, then five more. All 68 review comments on **#920–#930** were enumerated; the checking depth is **not uniform and is not claimed to be**: #922–#930 were verified finding-by-finding against the tree, while **#920 (27 findings) and #921 (5) were spot-checked only** on their P1/governance items — both clean (`p1_noise_floor.py` carries an explicit `SUPERSEDED by p1_ci_vs_floor.py` header that fixes the decoded-error framing *and* the 255-vs-256 bucket-edge bug; the merged **#917** entry has exactly one commit in its whole history, `4be809c8`, so it was never mutated). **The remaining ~30 older coderabbit findings on #920/#921 are UNVERIFIED here** — recorded as such rather than absorbed into a clean-sweep claim. Result within the verified range: **#922 / #924 / #925 / #929 carry zero review comments**; **all 27 findings on #926 are fixed in the tree** (verified individually: `grid_pts` returns exactly `n` and the E2 JSON is regenerated at 64/64/64 · 256/256/256 · 1024/1024/1024; `subgrid_min` wraps longitude via `np.take(..., mode="wrap")`; `find_center` returns `None` on an empty mask; F7d tests `>= 40.0` matching its key; `CT_F12` emits `NO-VERDICT-INSUFFICIENT-N` instead of `pass: true`; storm metadata persisted; `d_dx` uses `np.roll`; `go_territory` writes `__file__`-relative; E6 requires a net decline; the 93–97 % headline superseded by 90.9–94.3 %); **#923's plan-status P2 is resolved**. Three findings on **#927/#928** were genuinely open, and all three were numbers already frozen in append-only ledgers.
