builtbykev f61ec6b391 Read integrity, as-of context, and the shadow matchup resolve (A1-A7)
Seven orders of measurement-first repair. The served grade does not move.

A0/A1 — the unordered page walk returned the right COUNT and the wrong ROWS:
410-617 of 2,490 duplicated with an equal number never returned, while
rows.length matched the server exactly. safePaginate orders on a real unique
key, verifies the tuple at runtime, and THROWS on a query error instead of
treating it as end-of-data. Both hits PROVES are withdrawn: they were drawn
through that reader, and defense_by_direction's distinct-n was likely below
the gate floor all along.

A2/A2b — rolled across every reader: 11 FAIL -> 0. Composite keys pulled from
pg_index (the context tables are dated-composite and had no single unique
column). The unordered helper is deleted, not parked.

A3 — ledgerService and retentionService defaulted the SAME env var to
DIFFERENT versions, so no ledger row ever carried the marker eligibility
requires. One source now. model_snapshots settlement moved onto the cron:
15,484 -> 28,894 settled, repaired-champion 0 -> 7,556.

A4 — hitsFactorContext takes an as-of cutoff. Refusal over reconstruction: no
row at-or-before the date means the factor does not apply, never the nearest
row. Live path unchanged, proven 400/400 on real rows.

A5 — factor_inputs freezes what the factor READ, never the multiplier, so an
audit can recompute and check. It also recorded the finding: the three hits
factors have NEVER fired. prop.opponent and prop.opposing_pitcher are read by
the resolver and written by nothing.

A6/A7 — matchupKeys resolves those keys from the posted lineup plus the
schedule's probable pitchers, and fires the factors into a SHADOW freeze:
248 fires on 308 props, 245 of which would move the grade. The served
forecast is untouched. specs/a8-shadow-factor-gate.md pre-registers the test
that decides whether they ever go live.

Nothing is turned on. CALIBRATION_DEPLOYED stays []. Both verdicts stay
withdrawn. 4,772 tests / 371 suites green, web build exit 0, read-integrity
harness 34/34.

builtbykev 3081c92e00 Per-archetype grade bands: built, gated, and the rescale blocked twice
The premise does not hold. proven-status.js run fresh: PROVEN_SET is
EMPTY, no archetype x stat reaches the gate. pitcher_contact_profile has
a CI upper bound of exactly 0.0000 and platoon_severity is held on
4.5%-contaminated splits, so the proven set is one factor, pooled, not
three archetype-conditioned ones. The specific pattern the order names --
defense strong for GHOST/BRUSH, null for BOMBER -- is the one I measured
running the OTHER WAY yesterday, both noise-dominated.

But the second blocker is new and matters more, because it would stop the
rescale even if the factors had proved: the grade does not separate
within any archetype. Every archetype collapses to ONE band at the
corrected bar, because bands merge when their intervals overlap and
publishing two letters we cannot tell apart is a distinction we have not
measured.

Uncorrected, so the ranking is visible rather than hidden by the bar,
this INVERTS the order's design. The order gives contact types the
factor-rich treatment and power types honest base-rate, reasoning that
single-game hits are variance for a power profile. Measured:

  BOMBER n=466  corr(p_win,outcome) +0.207  quintiles 0.75 0.62 0.60 0.48 0.48
  GHOST  n=192  corr(p_win,outcome) -0.007  quintiles 0.47 0.63 0.74 0.58 0.45

BOMBER is the one archetype the model ranks, and it splits into a real
A 0.660 / B 0.481 at 95%. GHOST is flat, and non-monotone -- its most
confident reads hit 47% while its middle reads hit 74%. Shipping as
specified would have given the factor-rich treatment to the archetype the
model reads worst and left base-rate on the one it reads best. That is
mechanically sensible in hindsight: a power hitter's hit tracks whether
he can damage the arm, a contact hitter's depends on balls finding holes.

BOMBER's split does not survive the cumulative correction at 106 tests.
Exposing it by loosening the correction is the curve-to-make-A's the
order forbids, so it stays one band.

BUILT: gradeBands.js -- lift against the archetype's OWN base rate (the
same 62% is lift for a 45% profile and a deficit for a 68% one),
indistinguishable neighbours merged, thin bands PROVISIONAL not dropped,
Wilson intervals widened by the cumulative correction. The two-bar rule
is structural: proven-alone, calibrated-alone and neither all return
base_rate with the reason stated, so with nothing proven no
factor-informed band can be produced at all.

reasoning() is built and tested but NOT wired to the card -- there is no
per-archetype band being served, so attaching the copy now would ship
product language for a rescale that does not exist.

NOT BUILT: the specified power-type reason "the matchup edge is in
total_bases". total_bases is recorded INCONCLUSIVE (+0.0038, CI
[-0.068,+0.075]). Wiring it would assert an edge measured as
indistinguishable from zero -- the exact fabricated-reason failure this
module exists to prevent.

BOMBER x hits is 29 rows short of the gate and is the archetype the model
actually reads. That is the first slot to test, not GHOST.

Counter and frozen clusters byte-identical. No letter was moved.
