fix(research): require the v2 reproduction, and correct the P1-cap denominator
Two review findings, plus a lost-edit repair. v2_reconstruction is now a required variant. It carries every published figure the reproduction rests on (avg, p80, max, P3-pegged, W1-live), so a run without it could emit a confident, non-provisional recommendation having checked nothing against v2 at all -- while the methodology doc claims v2 and v3 are reproduced first. The default invocation is now derived from REQUIRED_VARIANTS so the two cannot drift, and a test asserts the default satisfies its own requirement. The doc and the P1_TREND_BREAK_ANCHORS comment still justified skipping the P1_SCORE_CAP with 17/408 = 4.2%, which is the all-session share and does not evaluate the rule. The rule names sessions with State >= 40: 47 of them, P1 sole argmax on 17 = 36.2%, against P2's 16 and P3's 14. Conclusion unchanged -- well under the 80% trigger -- but the published rationale now states the metric that actually decided it. Root cause of that survival: the earlier correction WAS made, but in a script that applied several substitutions and wrote the file once at the end. A later substitution raised, so the successful edits were discarded with it. The "Unlike P3 and V1 ... P3's do not" fix was lost the same way and is restored. Also adds tests for the refusal paths themselves -- missing required variant, unknown variant, custom window with no calendar anchor. They were verified by hand last round but left unpinned, which is the same shape of problem as the optional gates they exist to enforce. All return before any network call. Deliberately not done, as not load-bearing: recording the oas400 variant's missing-credit session count (the truncation conclusion rests on the distribution mismatch, which is already recorded), and generalising _pipeline_gates for arbitrary --end/--sessions windows.

fix(research): make the calibration artifact live up to its refusal guarantees
Review of the v4 evidence path. The shipped sensors, bands, methodology bump and
categorical allowlist were found sound; these are gaps in the harness that
produced the evidence for them.
The recommendation gates were optional, so they were not gates. The calendar
anchor lived behind --expected-first-session, which defaulted to None -- so the
committed artifact had no first-date check at all, leaving only a session COUNT
that is tautological (the harness slices the tail of the price series to whatever
was asked for). And the state_v4 <= state_v3 invariant was appended only when
both variants were present, so `--methodology v3` alone could still emit a v4
recommendation having never evaluated v4. The anchor is now a published constant
asserted unconditionally, required explicitly whenever --end/--sessions are
overridden, and v3+v4 are mandatory. Both refusals exit 2.
The P1_SCORE_CAP decision was taken on the wrong population. The agreed rule was
"sole price argmax on >80% of sessions with State >= 40"; the harness reported
only all-session counts and the doc concluded from 17/408 = 4.2%. Measured on the
actual population: 47 qualifying sessions, P1 sole argmax on 17 = **36.2%** (P2
16, P3 14). Still well under 80, so the conclusion holds -- but it was reached
from a denominator that did not test the rule, and 36.2% is a materially
different number to have on the page.
Provenance did not identify the code that produced the artifact. It recorded

feat(regime): cut the risk monitor to v4 — desaturate VIX and the trend break
Two sensors saturated in exactly the range where resolution matters, and the top State band had no headroom. Calibrated with scripts/run_regime_monitor_calibration.py over the 408 sessions ending 2026-07-24; the shipped code reproduces that run's band shares exactly (78.9 / 13.0 / 4.7 / 3.4). V1 read VIX 30, 50 and 82 as an identical 100 — the same defect v3 had just removed from P3, left in place one sensor over. In the window it flattened five distinct April-2025 prints (52.33, 46.98, 45.31, 40.72, 38.57) into one value. Now an anchor table reaching full scale at 55, not at 2020's ~82: anchoring the top at a once-in-a-generation print would make VIX 50 read only ~70. Pegged on 14 of 408 sessions before; none now. _under_200 returned a bare 0/100, so P1 printed 100 the moment SMH and QQQ were both under their average — and since the price pillar takes max(P1, P2, P3), that pinned the pillar and stopped P3's ladder resolving for the whole of a selloff. Now graded by depth below the 200-DMA, with a deliberate floor of 20 at the crossing: the break is a genuine binary event, only its depth is graded. Pegged on 46 of 408 sessions before; none now. A 2% break reads ~30, not 100. max() was KEPT — the defect was the step function feeding it, not the vote, and v3's "one capped vote for correlated reads" rationale still holds. P1 is the sole price argmax on 17 of 408 sessions (4.2%), so the P1_SCORE_CAP fallback drafted during design was measured as unnecessary and not shipped. STATE_BANDS breaking 80 -> 65, and only that threshold. Credit returns 0.0 (not None) when calm, so it holds its 20 points pinned at zero and price + breadth + volatility at literal maximum summed to exactly 80.0 — v3's threshold to the decimal, with nothing above it. The sensor is deliberately unchanged: a calm-credit selloff genuinely is less stressed. What was stale is the band, fit on v2 while credit's since-removed percentile leg still contributed. A 2022-style AI/tech drawdown with calm credit computes to 70.3 (no death cross) or 74.0 (with one); 70 would have left 0.33 points of headroom, reproducing the defect. Chosen by scenario arithmetic, and the realized breaking share then lands on 3.4% — the same as v3's, arrived at independently. "v4" added to CATEGORICAL_FUNDAMENTAL_METHODOLOGIES in this same commit, which is load-bearing: that set is checked against the STORED blob, so bumping without it discards the collected observation on first write, leaving fetched_at null and locked false — and update_regime_monitor then fires a paid LLM refresh on every run, forever. Now guarded by a test parametrised over v2 and v3 stored blobs. SENSOR_REVISION deliberately stays 2: a METHODOLOGY change already forces a full reseed via _parse_snapshot, and bumping both would imply the reseed was revision-driven. QUADRANT_STATE_DIVIDER stays 50 because only breaking moved, so alert_service, RegimeChart and the quadrant tests need no change. A new test enforces divider == band boundary on both axes, which nothing did before. Doc renamed to regime-monitor-v4.md with a tombstone at the old path (commit messages cite it), the three open questions converted to resolved with the reasoning that closed them, and indexed in docs/research/README.md for the first time. The P2 limit is stated honestly: _death_cross pegs at a -5% MA gap, so a deep selloff still reaches 100 via P2 — v4 repairs the shallow-to-moderate break, not "the price pillar no longer pegs". DEPLOY: the first run reseeds ~464 sessions. Expect one phantom quadrant alert (the dedup key carries basket_hash, not methodology) and re-run the Event Study manually — its cached report self-invalidates but does not self-regenerate.
