When σ_z/z ~ 1 the Gaussian hits the physical z ≥ 0 +boundary; the asymmetric truncation interacts with the steeply rising w_pop(z) ∝ dV_c/dz (∝ z² +at low z), and the correction stops exactly cancelling → residual HIGH bias. The deep-venue +analog is a **membership-support kernel leak**: a hard z-window over a common D fails to keep the +host kernel truncated consistently.

REFUTER pass (mandatory — try to prove each CONSISTENT wrong) + +Per W-CONF-13, the tracer's own synthesis can be confidently wrong. Strongest dissent per verdict: + +- **M2 (mass) refuter — strongest overall dissent.** "CONSISTENT" rests on the injection CSV + `"M"` column actually holding `M_z`. The lift and the store are two *different* code sites + (`main.py:899` computes it; `:983` writes it) — the W-PRE-12 lesson is that a transform + applied to multiple outputs must be invariant-checked on *every* output, and the original + 2026-06-20 bug was exactly a second write site (injection CSV) that stored source-frame `M` + while the CRB path was guarded. I read the write as `"M": redshifted_M`, which is correct — + **but I did not find a test that asserts the injection CSV column is `M_z` (only the CRB path + is guarded by `test_parameter_space_h`).** If a future edit reverts the CSV write, no test + fails. Residual risk: **the paired "every-output invariant" test (manifest M2) is NOT present + in code** — the consistency is real *today* but unguarded. Also: injection truncates `M_z > + M.upper_limit` (`main.py:908`); at inference a catalog host with large `M_g` and `z_g~1` can + query `M_z_g` beyond the grid's populated mass axis → kernel extrapolation at the mass edge + (an "M_z edge clamp" exists, `3273fa5`, but edge behaviour under the survival estimator was + not independently probed here). + +- **M5 (depth) refuter.** "CONSISTENT" is *conditional*, and the condition is the dangerous + part: the p_det survival grid is only valid to the depth of the injection pool it loads. If + the campaign submits inference against a p_det grid built from a **pre-#20 (z≤0.5) pool**, the + survival tops out <1 Gpc and `p_det=0` for essentially all deep hosts — "silently valid-looking + garbage" (the code's own words, `:285`). The mitigation is a **hard ValueError**, which is + strong — but (a) it only fires at runtime on the cluster, which I cannot exercise; (b) the + `allow_shallow_pool` escape hatch exists (`posterior_combination.py:590`) and a + frozen-baseline re-eval threads it — if a campaign run inherits `allow_shallow_pool=True` the + gate is bypassed. **I could not verify the campaign's actual pool depth or that + `allow_shallow_pool` is False for the production run.** + +- **M1 (frame) refuter.** FRAME-AUDIT.md is dated to COORD-03 (2026-04-22); the `z_cmb` + catalogue migration (2026-07-02) rewrote catalogue columns. The rotation reads raw cols 8/9 + (RA/Dec) and the migration touched the *redshift* column (27→28), so the rotation input is + unchanged — **but** the campaign-prep explicitly requires "8-col schema confirmation" before + submit, and stale-schema catalogue backups exist in the tree (`*.stale6col_mar28`, + `*.zhelio_20260702`). If the on-disk campaign CSV has a shifted column layout, the rotation + would silently operate on the wrong columns. **I read the code path, not the actual campaign + CSV header** — schema/provenance is the classic HPC-3-layer gap. + +- **M3 / M4 refuter.** These are structural (which form / where p_det appears) and read cleanly + in the current code. The residual is historical recurrence risk: both were reintroduced once + by a *misreading of Gray's prose* (SCV: the equations were dropped as images). The code now + cites Eq. A.9/A.10 explicitly. Low residual risk, but the guard is a comment + one equivalence + test, not an invariant that would survive a confident re-misreading. + +- **B1 refuter.** The z_cmb migration is very recent (2026-07-02) and the PV-marginalization + (issue #16) landed 2026-07-03 — both inside the pre-campaign window. Recency is itself risk: + the fixes are less battle-tested than the M1–M4 fixes. Consistent in-code, but least-aged. + +**Refuter's bottom line:** the trace found no *active* divergence, but every "CONSISTENT" on the +two most recently-touched rows (M2 store-site, M5 pool depth) is **guarded by runtime gates or +comments rather than by a paired invariant test in CI** — precisely the manifest-M2/M4 "paired +test" column that reads `NONE FOUND` / partial. The consistency is a property of the current +code, not a property the pipeline *enforces on itself*. That is the honest gap. + +--- + +## 4. Overall advisory recommendation + +**`needs-human-domain-review` (one narrow question), resolving to `safe-to-submit` on the +traced classes once answered.** + +- **Not `fix-first`**: no live convention divergence was found on any of the 4 incident classes + or the HOST_DRAW_Z_MAX item. There is nothing to fix on the traced boundary. +- **Not unqualified `safe-to-submit`**, for three reasons that code-reading cannot close: + 1. **[decision needed] pp_coverage depth (Q7 / finding C-MTC-20260712-003)** — confirm the + per-seed `pp_coverage` calibration runs at the campaign depth (1.5 / campaign σ_z), not the + hardcoded `Z_MAX_POP=0.95`. If it runs at 0.95, the 4b#3 calibration gate validates a + shallower venue than production and (per SCV 2026-07-11) may miss a depth-dependent residual. + This is the single question to answer before submit. + 2. **[operational, hard-gated] injection-pool depth (M5)** — ensure the campaign p_det grid is + built from a **freshly regenerated z≈1.5 pool** and `allow_shallow_pool` is False for + production. If a stale pool sneaks in, the pipeline fails loud (ValueError), so this is + low-risk *given the gate*, but verify the gate is armed on the cluster run. + 3. **[declared, un-closeable] manifest incompleteness** — the trace is blind to convention + classes outside the 8 skeleton rows. Adjacent bias work (Fisher-frame/population, deep- + incompleteness floor, σ_z/z shallow venue) is live as of 2026-07-11 and is NOT a convention- + divergence of the traced kind, but it means "no divergence found" ≠ "no bias." The full + manifest (2–3d archaeology) is the durable fix and remains a named separate task. + +**What ratifying this verdict means**: you accept that the 4 documented divergence classes + +HOST_DRAW_Z_MAX are consistent in the current local code, that the pp_coverage-depth question is +answered (or accepted) before submit, and that the residual risk is (a) unenforced-by-CI +consistency on the two newest rows and (b) manifest-incomplete coverage — both stated in writing +here rather than discovered after a retired campaign. + +--- + +## 5.
