v3 was calibrated by replaying the series offline, but that harness was never
committed -- so its published numbers could not be re-derived, and a v4 cut would
have had to choose anchors by argument rather than measurement. This is that
harness, and it reproduces the published figures.
scripts/run_regime_monitor_calibration.py replays State/Warning session by
session from the same inputs the live job uses (Alpaca for all 33 symbols, FRED
for VIX and HY OAS), with no database: breadth and divergence come from
breadth_service's pure helpers. It never reimplements an unchanged live sensor --
_compute_index, _score_pillars, P2, P4 and the Warning sensors are imported and
called. Only candidate formulas (proposed v4) and retired ones (v2, gone from the
codebase) are defined here and patched onto the module for a variant's duration.
Reproduction of the 408 sessions ending 2026-07-24, against the figures in
docs/research/regime-monitor-v3.md:
v2 State avg 22.6 -> 22.68
v2 State p80 35.1 -> 35.1 exact
v2 State max 91.2 -> 91.2 exact
v2 P3 pegged 39 -> 39 exact
v2 W1 live 108 -> 108 exact
v3 State max 87.4 -> 87.4 exact
v3 band shares 73.3/15.0/8.3/3.4 -> 73.0/15.4/8.1/3.4
Three things the harness had to get right to reach that, each of which was
initially wrong and caught by a gate rather than by inspection:
- "W1 live 108" counts NONZERO sessions, not non-null ones. v2's divergence
gate returned 0.0 during any decline (v3 tapers instead), so the retired
divergence formula had to be reconstructed too.
- v2 sliced HY_OAS_REFERENCE_YEARS = 10.0 per session, not v3's 700 days. The
percentile leg ranks against that window, so replaying it short shifted the
middle of the distribution while leaving the max exact.
- The published v2 numbers correspond to FULL OAS coverage. Replaying v2 with
the 400-calendar-day fetch it shipped with yields max 100.0 and 133
credit-less sessions -- so that truncation was not in force when the figures
were taken. Recorded rather than assumed.
The script refuses to emit a band recommendation unless every hard gate passes
(33 symbols fetched, per-symbol warm-up and final bar, full basket on every
session, calendar anchors, 100% coverage, and a row-wise state_v4 <= state_v3
invariant), and exits non-zero. It is meant to be structurally impossible to read
a calibration result out of a run whose pipeline did not validate. No v4 code
ships in this commit.

Local dev uses a Dolt clone of post-no-preference/earnings under dolt-data/
(git-ignored). Production keeps clones in DOLT_DATA_DIR outside the repo tree —
the deploy is rsync --delete of the tree, so a clone inside it would be unsafe.

Four-arm results: 505 stays positive (softer on deep history); liquid breadth
destroys book under current knobs. Stop tracking 1.3GB pkl cache under reports/.cache.
The reports are the evidence behind the production baseline, so they belong
next to the README that quotes them rather than living only on one machine.
Un-ignores reports/*.json (~2.6 MB compressed for all 11); the snapshot DBs
they run against stay ignored.
Renames the reports to a single dated scheme so they sort chronologically and
say what they measured. Each name is derived from the report's own contents
(the atr_trail_sweep / regime_overlay / blue_sky_projected / sizing_test
sections, and the qualified counts that identify the A/B arms), not from the
ad-hoc slugs they carried before. The run the README quotes is now
backtest-20260711-prod-baseline.json.
reports/compare_reports.py loads every report into one sortable table
(portfolio monitor, entry variants, exit policies, portfolio sim), filters by
report and lookback, and highlights the best row for a chosen metric — max
drawdown correctly ranking lowest-as-best. Stdlib tkinter, no dependencies.

- PerfChart moves into the left column under Open Positions
(half-width), balancing the radar column.
Cleanup:
- Design mockup pages (DesignMockups / DesignHorizon / DesignOrbit)
and their routes removed - the redesign has shipped; the mockups
live on in git history. Main bundle shrinks ~97 kB and the
chunk-size warning goes away.
- frontend/tsconfig.tsbuildinfo untracked and gitignored (incremental
build artifact that churned in every commit).
- Dead npm test / test:watch scripts removed - vitest was never a
dependency; CI already skips the step via its vitest guard.
