MEASURE-ONLY. No promotion, no flip, no tier spend. Live path
byte-identical: CURRENT_RULER_VERSION still v1_first_book, model still
consumes MODEL_BOOKS only.
MANDATE 1'S PREMISE DOES NOT HOLD. The p_win calibration is
RULER-INDEPENDENT, confirmed two ways: estimateProbability takes
{gameLogs, line, statType, features} and never sees a market price, and
the calibration fits p_win against OUTCOMES. Reliability and resolution
are both p_win-vs-outcome measures, so fair_prob cannot enter either.
There is nothing to re-fit -- the ruler changes edge, CLV and takeable,
not calibration.
I RETRACT MY OWN LABEL. I declared the MLB isotonic result PROVISIONAL
"because it was measured against the bent ruler". That over-applied the
ruler caveat to a measurement the ruler never touched. The result was
never contaminated; it moves PROVISIONAL -> DECIDED, not by re-running but
because the gate I attached does not apply.
RAN THE GENUINELY RULER-DEPENDENT QUESTION INSTEAD -- does a median
consensus rescue EDGE? Timing held constant (both rulers at close; a
lock-time reconstruction joins only 43 rows, and mixing lock-incumbent
with close-consensus would confound WHEN with WHAT).
n=200 MLB settled rows: mean |ruler gap| 0.0085. corr(edge_v1, outcome)
-0.0101; corr(edge_v2, outcome) -0.0220; corr(p_win, outcome) +0.2598.
THE HEADLINE: p_win predicts outcomes at +0.26 while p_win minus the
market predicts nothing under EITHER ruler. Subtracting the market price
destroys the signal -- a direct empirical vindication of the identity now
at the top of CLAUDE.md. Market edge is not merely a poor criterion here;
it is a strictly worse instrument than the raw forecast.
CALIBRATION REFRESH (ruler-independent, but n grew 119 -> 250):
time-forward holdout n=125, reliability 0.0846 (was 0.0939), resolution
0.190 (was 0.123). Both hold and both improved on a fresh later window
the earlier fit never saw. Independent replication.
THE LIMITATION THAT BLOCKS A FULL VERDICT: closing_captures holds only
MODEL books -- exchange quotes were never stored, because normalizeProps
discarded them until yesterday. Mean 1.97 books in the historical join. So
this tested a US-books-median ruler, not the exchange-inclusive consensus
whose live delta showed p90 +10 points. That ruler is UNTESTABLE on
existing data at any n. Per Mandate 4's third outcome: inconclusive, not
forced.
SEPARATE FINDING -- LIVE FEED REGRESSION: pinnacle MLB captures went 4,022
-> 0 on 2026-07-31 and have not returned, while every other book continued
(103,940 captures in the prior 10 days). This also corrects an Order Zero
claim of mine: "no sharp anchor exists in our feed" was accurate for the
day measured but wrong generally -- pinnacle was there until 07-30 with
17,090 two-sided captures. line_type='sharp' is a label in closingCapture
via SHARP_BOOKS, not a separate provider. We had a sharp anchor and lost
it two days ago; not caused by anything in this session.

Measure-only. p_win not flipped live, no grade rebuilt, no calibrator deployed.
Per the doctrine, MLB and WNBA were fitted, selected and judged as SEPARATE
models — and they reach opposite verdicts. No global instrument was fitted.
METHOD: time-forward split per sport (earlier fits, later proves). Both
instruments fitted on TRAIN only — single-parameter Platt and
isotonic-with-pooling. Inputs p_win + outcome only; no market field, no closing
value, no lookahead. Nothing about edge/CLV/beat-the-close enters any pass/fail
line.
MEASUREMENT CORRECTION made mid-run: the first pass reported mean|p - outcome|
(~0.46-0.51), which is NOT calibration — it is noise-dominated individual error
on 0/1 rows and would have made every instrument look identical. Reliability is
only meaningful on BUCKETS (bucket mean predicted vs bucket actual rate,
n-weighted), the metric T0 used. All reported numbers use the corrected metric.
HOLDOUT RELIABILITY (lower better): MLB n=119/4 buckets — raw 0.1038, Platt
0.1120, ISOTONIC 0.0939. WNBA n=93/3 buckets — raw 0.1322, Platt 0.0491,
isotonic 0.0667.
HOLDOUT RESOLUTION: MLB raw 0.1388 -> Platt 0.1284 -> isotonic 0.1225.
WNBA raw -0.1201 -> Platt +0.1269 -> isotonic +0.0322.
Fitted Platt: MLB a=-0.381 b=+0.705; WNBA a=+0.040 b=-0.081.
MLB QUALIFIES, MODESTLY — instrument selected BY HOLDOUT, not assumed: isotonic
beats both raw and Platt, and Platt actually made MLB worse. Reliability improves
0.1038 -> 0.0939 (~10% relative, real but modest) and resolution SURVIVES
(0.1388 -> 0.1225, not crushed). Both Mandate-3 conditions hold.
WNBA ABSTAINS — its Platt result is the best number in the report and is REJECTED
as a fake win. The fitted slope is b = -0.081, negative and near zero, so
sigmoid(0.040 - 0.081*logit p) is nearly constant at ~0.51 for every input: it
"calibrates" by discarding the prediction and emitting the base rate, which is
exactly the failure Mandate 3 pre-registered. Its apparent resolution gain
(-0.120 -> +0.127) is the sign flip, not skill — it would serve the opposite of
its own forecast, fitted on n~96 of anti-signal. Isotonic says the same quietly
(resolution collapses to +0.032).
HONEST CEILING: MLB is a usable-but-unimpressive forecaster (holdout resolution
~0.12, reliability ~0.094, n=119); WNBA has no honest forecast today. Holdout n
and bucket counts (4 and 3) suffice to reject WNBA and prefer isotonic for MLB,
NOT to certify a letter ladder, and the T0 pathology is reduced rather than cured.
CANNOT DETERMINE: per-archetype calibration (Mandate 3d) — bucket n falls below
the reporting floor once split by sport AND archetype on 442 rows.

STOPPED at the T0 gate as instructed. Nothing fixed, no recalibration applied,
no grade touched. T1-T4 deliberately not run.
T0 FIRES ON BOTH PRE-REGISTERED CONDITIONS.
Condition 1 (mean |predicted-actual| > 0.05): MLB ~0.094, WNBA ~0.139.
Condition 2 (monotonic slope): over-confidence GROWS with the prediction —
MLB +0.034 -> +0.043 -> +0.084 -> +0.190 -> +0.189; WNBA +0.044 -> +0.109 ->
+0.349. Worst cases: MLB predicted 0.842 actual 0.652 (n=23), predicted 0.917
actual 0.727 (n=11); WNBA predicted 0.730 actual 0.381 (n=21).
WHY THIS EXPLAINS THE INVERSION, mechanically: p_win is over-stated and the
overstatement SCALES with p_win, so p_win - fair_prob_lock is largest exactly
where p_win is most inflated. Those props hit less than claimed, so the edge
measure correlates negatively. The market was never the problem —
fair_prob_lock is not a bent ruler, the thing subtracted from it is. It also
explains why p_win ALONE still carries signal (+0.23 MLB): rank survives
miscalibration, differences do not.
This independently reconfirms the 2026-07-26 calibration finding (+0.02 at p<.5
-> +0.19 at p>=.8) on a newer, larger population, so it is structural rather
than sampling noise.
PART 0: P0a — only the GRADED side's fair prob is stored (fair_prob_lock;
no opposite-side field), so T1's two-side-sum check cannot run and must use the
stated no-vig recompute fallback. P0b — projection_locked_at exists as a
timestamptz so T2 is potentially runnable, but distinctness from lock time was
NOT verified because T0 gated it.
Two cautions recorded before Part 2 runs: the top MLB buckets where the error is
worst hold n=23 and n=11, so a flexible per-bucket correction would fit noise —
isotonic with pooling or single-parameter Platt is safer; and calibration fixes
magnitudes, so if the market is genuinely better the repaired edge may still land
at ~0, which would be the honest ceiling and gets reported rather than graded
around.

STOPPED at the Part 1 gate. Nothing rebuilt, no grade changed, no cutover.
THE FINDING: grading on p_win vs fair_prob does not work. All three candidate
edge formulations correlate NEGATIVELY with outcomes, on both sports, overall,
and in both time splits (n=432 decided rows carrying p_win AND fair_prob_lock):
ALL n=432 champ -0.0016 p_win ALONE +0.1221 additive -0.0615 ratio -0.1161 logodds -0.0438
MLB n=240 champ +0.0984 p_win ALONE +0.2278 additive -0.0336 ratio -0.1350 logodds -0.0124
WNBA n=192 champ -0.1143 p_win ALONE -0.0842 additive -0.1326 ratio -0.1281 logodds -0.1243
Subtracting the market's lock-time fair probability destroys and inverts the
signal. The plain reading: props where the model most disagrees with the market
are LESS likely to hit — the market is better than the model, so "edge vs market"
is anti-predictive here, while the raw probability retains some skill alone.
WHAT DOES CARRY SIGNAL: p_win alone, MLB only, and it is modest. Time-forward
split — TRAIN (07-21..07-26, n=120) r=0.2770; HOLDOUT (07-26..07-30, n=120)
r=0.1647, with the additive edge negative in BOTH halves. So p_win survives
forward validation directionally but the holdout is NOT significant (t~1.81,
p~0.07). Suggestive, not proven.
WNBA MUST ABSTAIN: every measure negative including p_win itself (-0.084). Forcing
one threshold across both sports would make a coin-flip sport look sharp, which the
order forbids.
LOOKAHEAD GUARD SATISFIED: fair_prob_lock is the lock-time field, populated on 432
decided rows, range 0.145-0.713. closing_prob (415 rows) is the CLOSE and was NOT
used in any correlation — using it would have manufactured a correlation.
SAMPLE REALITY: 1103 decided rows but only 432 carry both instrument fields, so a
per-sport train/holdout split leaves ~120 per half — enough to show direction, not
to certify a letter ladder.
I did not tune toward a win: three pre-registered candidates were tested and all
three failed; picking a fourth because the first three lost is the overfitting the
order guards against. Recommended instead: grade MLB on p_win alone with WNBA
abstaining and label it modest/accruing (A-RATED hold stays); or wait ~6 weeks for
n~500 MLB; or investigate WHY the market-relative edge inverts, which is the more
valuable question.
Both queries committed at scripts/grade-correlation-proof.sql so no number here
has to be taken on trust. Working settlement untouched; dead resolve endpoint not
wired.

Per-book prices existed only transiently (odds cache, ~1h, raw names, grade-path
input); every grade-path persistence point collapses to one book. The
/api/books feature was built+mounted but non-functional (fed FLAT rows to a
GROUPED comparator -> always empty).
Phase 1: bookPriceStore captures per-book prices from `props` BEFORE dedupeProps,
keyed nameKey|stat, into bookprices:{sport} (SNAP_TTL) in snapshotService. Fenced:
reads props, writes its own key, read by nothing on the grade path. Grade proven
byte-identical (test + no-grade-path-reference grep test).
Phase 2: scripts/measure-book-spread.js reports same-line best-vs-worst spread
(cents + implied-prob pts), per sport, never pooled. Pre-registered crown
threshold: median >=8c OR >=2pp. Runs post-deploy on real data.
Phase 3 (backend): compareProp is honest-absent (single-book/flat -> no crown)
and the crown is gated (BOOK_CROWN_ENABLED, default OFF until Phase 2 clears).
/api/books repointed to the snapshot-locked store (fallback odds cache),
nameKey-matched; `source` field is the deploy fingerprint.
HELD unchanged: dedupeProps, snapshot dedup, selector, grade, champion,
challengers, ranking, edge_pct/ev_pct. UI routing of BookComparison + crown
treatment deferred to post-measurement (gated on Phase 2). Full suite 3834 green,

Phase 0 gate PASSED: the join is clean. No FK exists; the natural key
(sport, player_key, stat, line, side, game_date) yields 283 clean 1:1
joins with ZERO ambiguity. game_id is NOT usable — 400/550 snapshot rows
carry UNK@UNK because home/away names weren't threaded into the grader
until Order 1.6. Non-joining rows are EXPECTED, not errors: retention
stores both sides plus refusals; the ledger keeps only the graded side.
Outcomes are NOT denormalized — ledger_entries stays the source of truth.
BUILT TEST-FIRST, and the first property proven is the REFUSAL, not the
math. Below threshold the harness emits INSUFFICIENT with n and the
shortfall and NO rate anywhere in the payload, so a downstream renderer
cannot surface one by accident. A test asserts the payload contains no
hit_rate number at all.
- Wilson intervals (correct at the n we actually have, unlike the normal
approximation which emits negative lower bounds).
- Strata NEVER mix sport or model_version.
- Denominator excludes quarantined, void, unrecoverable, pending, push —
asserted by test.
- Monotonicity refuses to RANK buckets whose intervals overlap; it reports
"not distinguishable on this sample".
- Probability calibration (Brier + reliability) also respects the
threshold: a thin sample returns status INSUFFICIENT and a NULL score.
- Replay seam reads the STORED feature vector only. A row whose input was
never retained is UN-BACKTESTABLE, never scored with substituted current
data. Identity replay reproduces the live prediction exactly.
The tests caught a real bug in my own code: `Number(null) === 0` let a
null p_win through as a confident 0% forecast — this codebase's signature
fabrication bug, inside the harness whose entire purpose is refusing
invented numbers. Fixed with a strict null guard.
FIRST LIVE RUN — the correct, passing output:
VERDICT: INSUFFICIENT_HISTORY (can_validate=false)
283 joined -> 35 scored (120 quarantined, 124 pending, 4 terminal)
C n=18 (short by 2), B n=17 (short by 3)
strata: mlb 7, wnba 28 — never mixed
migration 028 adds harness_results (append-only trend log; INSUFFICIENT
rows are expected and correct) and opsWatch.harnessStaleAlarm pages if the
harness stops running — a validator that isn't running looks exactly like
one that keeps passing.

Order 2 Phases 2 + 4. Pre-heal rollback point secured first:
vyndr-20260720-093821.dump (856,890 bytes) VERIFIED ON THE BOX, not just
exit 0.
MIGRATION 027 — two DISTINCT exclusion scopes, deliberately separate:
- quarantine_reason: the row's GRADE is untrustworthy (wrong_opponent_grade).
The row REMAINS a real public settled result — the bet happened, the
outcome is real — but it must never train or validate, so
getModelAggregate now excludes it from the denominator alongside
void/unrecoverable.
- analysis_flags: the row is VALID for settlement and the record but
unattributable for PER-GAME analysis (doubleheader dates). Explicitly NOT
filtered from aggregates.
Collapsing these would either wrongly drop 166 doubleheader rows from the
record or wrongly keep 25 wrong-opponent grades inside model validation.
Tests assert both directions, including that analysis_flags is NOT filtered.
Also adds re_settled_at + settlement_source to model_snapshots.
DNP VOIDING RE-ENABLED — reversing my own Order 1.5 disable, with scrutiny,
because its premise was FALSE. Order 1.5 assumed a missing player row meant
the row's DATE was wrong. The Phase 0 dry-run disproved it: across every
bindable row the stored date matched a real game (MIS-DATED: 0), and the
players I had cited as counter-evidence were genuine DNPs on their true
dates (Freeman 07-18; Kwan/Hedges/Davis 07-17 — their teams played, they
did not). The evidence is positive: games FINAL + no line in a full-season
log = no bet existed.
I got this wrong twice tonight in opposite directions; the dry-run is what
caught it. Recording the reasoning in the code so the next reader sees why
the flag flipped back.

PHASE 1 — HOST KEY STATICALLY PINNED. ssh-keyscan -p 23 returned an
ED25519 key whose fingerprint EQUALS the out-of-band value
SHA256:XqONwb1S0zuj5A1CDxpOSuD2hnAArV1A3wKY7Z3sdgM, so it is safe to pin.
scripts/storagebox_known_hosts now carries that verified line and ships to
the container (Dockerfile already COPYs scripts/). backup-db.sh uses
StrictHostKeyChecking=yes + UserKnownHostsFile=<pin> instead of
accept-new, which was trust-on-first-use and would have accepted an
impostor on the very first run. A missing pin file REFUSES the push rather
than silently falling back. Never weakened to accept-new/=no//dev/null —
a test asserts that on executable lines.
PHASE 1b — REMOTE DIR GUARANTEED. The box has only .ssh/, and rsyncing a
file into a missing parent either fails or silently writes the dump AS the
directory name — one file, overwritten nightly, reading as "backups exist"
while retaining exactly one. Uses rsync --mkpath when available, else an
explicit remote mkdir -p ahead of the push.
PHASE 2b — FAILED OFF-BOX PUSH IS NOW LOUD. Off-box is required, so the
failed-push path pages at "urgent" (was "low"/deferred) and the script
emits a machine-readable OFFBOX_OK=1/0/deferred that
POST /api/internal/backup/run surfaces as a distinct offbox_ok field.
Exit code deliberately still reflects ON-BOX durability — a good on-box
dump must not raise a false total-failure alarm. Surfacing the truth, not
manufacturing a failure.
No key material is echoed anywhere; only the PUBLIC host key is committed.

RETENTION (Phase 2, priority zero). History starts compounding tonight.
migration 025 model_snapshots — APPLIED to prod. Append-only, one row per
graded prop PER SIDE PER CYCLE, with a unique index on
(snapshot_id, player_key, stat, line, side) so a retried cycle cannot
duplicate. RLS on, service-role writes only.
What it captures that the ledger never did:
- features jsonb — the model's INPUTS. Without these a backtest can only
grade our own homework; with them any future model can be replayed
against the exact conditions this one faced.
- REFUSALS (refused + refusal_reason). The ledger drops them, so a gate
refusing props that would have WON is invisible — unmeasurable lost
edge. Captured via a new onGraded hook in gradeSlateService that fires
with BOTH sides before any filtering.
- grade_11, the pre-collapse grade. The 4-letter map throws away the
entire live C-/C/C+/B- range.
- model_version + code_sha on every row. ledger_entries mixes pre/post-fix
grades with no marker and cannot be separated retroactively.
- p_win / ev_pct / fair_odds / takeable / value — none of which any
permanent store held.
Wiring: analyzeViaEngine1 attaches _features/_grade_11 (underscore =
internal); gradeSlateService fires onGraded then STRIPS them so they never
reach a cache or API payload; snapshotService builds rows and persists
best-effort. Retention reuses the LEDGER's dateET/gameIdFor helpers so
rows share the ledger's natural key exactly — otherwise the settle pass
could never join outcomes onto them. Rows are written BEFORE the empty-
slate early return: a slate that refused everything is exactly the case
worth recording.
CONTRACT HELD: retention is injectable and every path is caught. persist()
returns errors, never throws; a missing Supabase client is SKIPPED, not an
error. A retention failure can never break a snapshot.
BACKUP: backup-db.sh now accepts BACKUP_SSH_KEY as base64 (recommended —
survives env-var newline mangling, which is how injected SSH keys usually
break silently) OR raw PEM, detected by decoding and looking for the PEM
header. Verified both forms detect correctly against a real generated key.

BACKUP_DIR is now a persistent volume (/app/backups), so the dump already
survives redeploys — the container-ephemeral risk that made this urgent is
closed. Storage Box SSH auth is not sorted yet, so the off-box push is
explicitly DEFERRED rather than failing:
- gated on BACKUP_OFFBOX=1 (plus BACKUP_REMOTE and BACKUP_SSH_KEY); until
then the script logs "off-box push DEFERRED" and exits clean.
- if an enabled push DOES fail, it is a LOW-priority "deferred" notice, not
a failure — the durable on-box dump succeeded, and calling that an
incident would train us to ignore backup alerts.
Adds the read-back check, because a backup nobody has read is a hope:
countRowsInDump() runs `pg_restore --data-only --table=X -f -` and counts
the rows between `FROM stdin;` and the terminating `\.`, proving the
archive CONTAINS the data rather than merely parsing. Needs no Postgres
server, so it runs inside the API container. Validated against a real
pg_dump from a scratch Postgres: counted exactly 604 rows.
GET /api/internal/backup/verify exposes it (newest dump in BACKUP_DIR,
size, table, rows_in_dump). Unit tests inject spawn/fs so CI needs neither
docker nor pg_restore.

Closing the backup for real. Three changes, each fixing something that
would have made the Storage Box target fail or silently rot.
1. SSH KEY COMES FROM ENV, not from the container. Generating a keypair
inside the API container was the obvious move and it is wrong: the
container filesystem is ephemeral, so the key dies on the next
redeploy and the off-box push starts failing silently. backup-db.sh
now reads BACKUP_SSH_KEY (a Coolify secret), writes it to a 0600 temp
file per run, and removes it on exit via trap.
2. PORT 23, verified live. Hetzner Storage Box runs full OpenSSH on 23;
port 22 answers with mod_sftp (SFTP only). Banner-checked both against
u635423.your-storagebox.de. rsync now uses
-e "ssh -p ${BACKUP_SSH_PORT:-23} ... -i <key>"; the old invocation had
no -e at all and would have gone to 22.
3. OFF-BOX PUSH IS NIGHTLY, not Sundays-only. A weekly push meant up to
six days of dumps existed ONLY inside an ephemeral container, which is
the same as not existing. Alert copy updated to say exactly that when
the push fails or is skipped.
Also adds POST /api/internal/backup/run (internal-key gated) so a real
backup can be TRIGGERED and OBSERVED — it returns exit code, duration,
output tail, and whether the remote + ssh key are configured. The backup
can only run where SUPABASE_DB_URL and the Supabase route live (this
container), and there was no way to fire or inspect it without a shell.
Connectivity established this session: Storage Box reachable from the dev
box on 22/23; Supabase :5432 NOT reachable from WSL2 (so the dump must
run in-container, as designed); docker IS available locally, so the
restore-verify can run against a scratch Postgres using the real dump.

FOUNDATION-FIRST re-order, phase 1 (tooling + safety).
BACKUP (highest-severity open item) — INSTALLED, not re-proven.
src/backupScheduler.js runs scripts/backup-db.sh nightly from inside the
API container, armed at boot in server.js. The container already has
SUPABASE_DB_URL, pg_dump and the Supabase route, so deploy == installed:
no host crontab, no Coolify click. Arming is deliberately opt-OUT (armed
whenever SUPABASE_DB_URL exists; BACKUP_CRON=0 kills it) because the S62
design was opt-in and nobody ever opted in — the DB went unbacked every
night for weeks. A failed run pages high-priority ntfy; silence is the
danger with backups.
Durability is the one part still needing a human: the container FS is
ephemeral, so a dump dies on redeploy unless BACKUP_REMOTE (off-box
rsync) or BACKUP_DIR (persistent volume) is set. The scheduler detects
that and pages a WARNING at boot rather than letting an undurable backup
read as "backed up". Runbook rewritten to lead with the code path.
MANUAL REGRADE TRIGGER — scripts/run-snapshot.js, runnable via
docker exec with no VYNDR_INTERNAL_KEY and no new HTTP surface. Runs the
SAME snapshotService.runSnapshot the cron runs (including the team-stats
refresh that powers opp_rank_stat), supports `all` and `--settle`, and
prints the grade/confidence distribution plus p_win/ev_pct presence —
which is the thing you actually want when verifying a grading change.
ACCESS BLOCKER, logged honestly in specs/model-train.md: there is no
VYNDR_INTERNAL_KEY in the local .env and SSH to the box times out from
WSL2, so I can neither curl the internal endpoints (which already exist
from S45) nor docker exec. The trigger is built and correct but only Kev
can run it until a key or SSH access exists. This is the highest-leverage
unblock for phases 2 and 3, which both need on-demand regrade+settle to
verify anything.
Also logged the standing cautions: CLV ledger stays private until
backtest-proven; "self-improving model" is unsupported marketing until
the loop closes; the engine is MLB/WNBA-calibrated and NFL/NBA/soccer
need their own calibration before the hub grades them (scaling gate).

Folds re-sequenced steps 1+2 into one change (Kev's call): same bug
family — features wired to sources that return null.
THE PROBABILITY LAYER WAS DEAD IN PRODUCTION. p_win/ev_pct/kelly/
model_odds/value were absent on 0/8 live grades because
gameLogService.getGameLogs returns null for MLB by construction and
depends on the offline Python service for NBA/WNBA, so meta.gameLogs was
[] for every sport. This was the S46 bug in a second location — that fix
gave featureCache an MLB branch (why grades still worked) but never the
estimator. featureCache.getStatRows now supplies normalized rows
([{date,[statType]:v}], most-recent-first) for every sport, feeding the
estimator AND consistency AND game_count_in_7d from one fetch.
VERIFIED on real props: p_win 25/25 WNBA, 8/8 MLB (was 0).
GRADE RANGE, ON MERIT — never by rescaling (permanent founder ruling:
minting A's without new information is a relabelled B sold as an A and
corrupts an append-only ledger).
- refreshTeamStats wired into runSnapshot — it had ZERO production
callers, so opp_rank_stat was permanently null and a +/-1.0 factor
could never fire. Test-env no-op (opsNotify precedent).
- L20 made SYMMETRIC: both branches were delta +1.0, so the season
baseline could only ever ADD. No negative path was a structural reason
D was unreachable. New l20_contradicts_* carries -1.0.
- game_count_in_7d derived from real logged dates (heavy_workload_7d).
- NOT wired, deliberately, with reasons inline: teamId (no team_id
column; getFeatures reads it top-level; factor also needs a starter-id
list) and season_type (ESPN 2 = REGULAR season; threading it raw would
fire veteran_in_playoffs in July). Dead code dressed as a fix is the
thing we are removing, not adding.
CALIBRATION GUARD (found by verifying, not assuming): consistency CV is
NBA-tuned; for a Poisson-ish stat cv ~ 1/sqrt(mean), so any stat with
mean < 4 auto-classifies boom_bust. First verification run showed 8/8 MLB
props boom_bust — a blanket -1.0 that dropped the board to all-C. Floored
at CONSISTENCY_MIN_MEAN=4 -> 'unknown' below. Absent beats wrong. MLB
low-count stats therefore still get no consistency factor: honest, not
fixed. Scale-free index-of-dispersion classifier is the open follow-up.
CONFIDENCE IS NOT A PROBABILITY: payloads carry confidence_basis:
'grade_band'. Corrected mlb-grade-degradation.md — its "25/25
grade<->confidence agreement" is a TAUTOLOGY (confidence is derived FROM
the letter, so it would report 25/25 even if every grade were wrong), not
a validation. Removed dead mlbGrader.js (referenced only by its own test)
and the stale computeFeatures comment claiming a penalty that never ran.
VERIFICATION (scripts/verify-grade-range.js, real props/logs/engine):
WNBA 25 props B 68%->32%, C 32%->64%, D 0->1 (4%); 11-step spread went
from 2 steps to 5 (C/C+/B-/D). The D is earned: Angel Reese assists o2.5,
p_win 0.365. Nothing flooded — grades got HARDER. A did not emit locally
because opp_rank_stat needs the Redis cache only prod populates (local
ceiling +3.0 vs the +4.5 A needs); reachability is proven arithmetically
and locked in tests. Prod A-emission is the outstanding fingerprint.
MARKETING HOLD: "A-RATED" (AccuracyBadge, TopSignals) is unsupported
until that fingerprint. Confirmed honest fallbacks render today —
/api/ledger/accuracy has B and C buckets only, so the badge shows
"MODEL · 63% HIT" and TopSignals self-hides. Nothing fabricated ships.
Suite 276/3286 green, web build exit 0.

SUPABASE_DB_URL is set in Coolify on the API service, and this WSL2 box can't
reach db.<ref>.supabase.co — so the backup runs INSIDE the API container, which
has the env + Supabase network. Made that real:
- Dockerfile: install postgresql-client (pg_dump/pg_restore) + rsync + bash in
the runner image.
- backup-db.sh: added an integrity fingerprint on every run — pg_restore --list
must parse the archive AND find ledger_entries, else the run FAILS + pages
(stronger than the size check; catches a corrupt/structureless dump).
- BACKUP-RUNBOOK.md: rewritten for the container-exec reality — host cron does
`docker exec <api> sh /app/scripts/backup-db.sh` (inherits env + network +
pg_dump), or a Coolify Scheduled Task. Full restore-fingerprint steps included.
MECHANISM FINGERPRINT (run locally, docker + pg16): seeded a ledger_entries
table (137 rows) → ran backup-db.sh (dump + validate: 22 archive objects,
ledger_entries present) → pg_restore into a scratch DB → 137 rows restored,
exact match. The dump/validate/restore path is proven end-to-end; it's the same
pg_dump/pg_restore that run in the container against Supabase.

scripts/backup-db.sh: nightly full-DB pg_dump via the direct connection string,
14-day local rotation, weekly off-box rsync copy, ntfy alert on any failure +
an undersized-dump guard (an empty dump is a silent failure). docs/BACKUP-
RUNBOOK.md: the ONE env var Kev must set (SUPABASE_DB_URL — the direct
db.<ref>.supabase.co:5432 URI, not the pooler), the cron line, the off-box
target (Hetzner Storage Box via rsync, simplest for a Hetzner box), and the
restore FINGERPRINT procedure (pg_restore into a scratch DB + count
ledger_entries — proves it's a real, restorable backup).

scripts/validate-grade-fix.js checks the live MLB snapshot for the three
degradation signatures (projection=0, edge=100 cluster, grade/conf disagreement)
— run after the next 14:00 UTC regrade to fingerprint the fix. The finding doc
now records root causes, fixes (commits 888d103/9fc4edf), the blast-radius SQL
(box can't reach Supabase directly), and the shared-path note for NBA/WNBA.
