PHASE 0 — contentEngine makes Truth Law structural, not careful. Copy is
token-substituted and an unbacked {token} REFUSES to render -- there is no
code path that produces a plausible default. The fact contract is asserted
before any string is built. Card and copy render from ONE fact object, so
a caption and a card cannot disagree. No live model writes factual claims:
the voice is in the template, the facts are pulled, and the voice-polish
port is deliberately unwired, because an LLM that can rewrite a sentence
can rewrite a number.
18 tests carry the proof. The one that matters most: ZERO IS PRESENT.
"0 cleared B+" is our most honest possible post, and treating 0 as missing
would be the Number(null)===0 breach wearing its opposite coat -- it would
silently delete exactly the post the brand is built on.
PHASE 1 — three templates, generating real posts from tonight's data:
hot hitters off the repaired full-season log, the honesty flex off the
real servedGrade distribution (2,140 graded / 70 cleared B+ / 42% not
separable / A unissuable), and streaks verified from settled outcomes only.
THE ENGINE CAUGHT A BUG IN ITSELF, and it is the sharpest lesson here. The
first run published "No hitter is meaningfully hot tonight -- we could
dress up a middling week as a streak. We don't." That was FALSE: the
box-score cache spans only the settled window, every player had under 20
games, and the pool was empty. A broken pull was publishing as considered
editorial judgement -- the fourth appearance of this class tonight and the
first where our OWN HONESTY COPY was the disguise.
Fixed structurally rather than by patching the number: an absent() variant
may now DECLINE to speak, and the template separates "no candidates at
all" (SKIP with a reason) from "candidates judged, none hot" (honest
absence). Both locked by test. Source corrected to mlbStatsAdapter.fullLog,
the same log the repaired champion reads.
PHASE 2 — cardRenderer emits SVG rather than canvas: it is text, so it
diffs in review and its numbers are greppable, which matters when the
whole claim is that the numbers are real. VYND white + R green, slashed-Y,
scanlines, mono. The card never formats its own facts -- every string
arrives pre-rendered and gate-checked.
PHASE 3 — scripts/generate-content.js writes copy + card per template to
.content-out/<date>/. Template N+1 is a registry entry: requires, pull,
copy, card, absent. Queued as stubs, not built: hot takes, daily reads,
"grades we DIDN'T give", cross-sport streak variants (the streak template
is already sport-agnostic -- settled outcomes and a noun).
FULLY ISOLATED: read-only on every source, zero writes to serving, model
or ledger tables. Serving fingerprint verified unchanged. The accrual clock
is untouched at 0 eligible dates.

The causal insight is right -- the game is a sequence and the matchup does
shift mid-game. The direction is backwards, measured on 93,663 plate
appearances from 1,238 games pulled free from statsapi.
LINK 1 PROVES. Starter batters-faced, point-in-time from his own prior
starts only, clustered on the pitcher: MAE 3.2226 -> 2.7990, delta
-0.4236, CI [-0.6006,-0.2731] at 0.9995 corrected for 107 tests, 1,706
starts across 204 pitchers. It finds the tail the chain needed -- early
exits are a 23.2% base rate, model-flagged starts are 34.0% early, lift
+10.8pp.
Scope correction inside Link 1: the order specifies fatigue x GAME
SCRIPT, but game script is not available at grade time -- whether he gets
hit tonight is the thing being projected, not an input to it. Only the
workload half is measured; the in-game half is recorded as a live feature,
out of scope, rather than quietly folded in.
LINK 2 DOES NOT PROVE, twice over. Model accuracy 17.2% vs an 8.6%
baseline -- doubling it sounds good and is not, since naming a specific
arm is wrong five times in six. And structurally the entity is the
BULLPEN: 39,629 post-starter plate appearances across 30 clubs is 30
readings, below the 40-cluster floor, the same permanent ceiling as park
geometry and team defence. LINK 3 NOT RUN, per the order's own rule.
THE PREMISE IS REFUTED, and this chains on nothing so it was safe to
measure:
vs STARTER n=48,492 hit rate 0.2444 +/-0.0038
vs BULLPEN n=35,760 hit rate 0.2373 +/-0.0044
The pen is 0.7pp HARDER. The specific effect the chain exists to exploit
-- early exit making later at-bats softer -- is +0.0010 on 35,760 PAs. A
well-powered null, not a sample problem.
What IS real is times through the order: TTO1 0.2351 -> TTO2 0.2515 ->
TTO3 0.2518. A starter does decay as the lineup sees him again, but that
advantage is SURRENDERED when he leaves, not extended -- the pen is
harder than his second and third time through. A modern bullpen is a
queue of fresh specialists throwing one inning each; there is no tiring
arm to punish.
So the insight survives inverted, and Link 1 stays valuable for the
opposite reason it was built: a likely early hook predicts the hitter
LOSES his third-time-through look (0.2518 -> 0.2373 on that PA). The
mispricing is on hitters who get an EXTRA look at a starter going deep.
BUILT: predictionGate.js + tests -- the two-part gate for a continuous
prediction. factorGate binarises outcomes for Brier, which would destroy
a target like batters faced. Same discipline, same THEATER verdict, real
scale.
PRE-REGISTERED NOT RUN: Link 2' using a PA-weighted bullpen AGGREGATE
rather than a named arm. Recorded rather than substituted in -- running
Link 3 on a swapped-in Link 2 is the assumed-link failure the order
forbids. Given the premise result its expected value is now low.
PARALLEL TRACK logged: total_bases n=948 pooled, BOMBER x TB 340, short
by 160. Sample-readiness only, not a verdict.
Counter and frozen clusters byte-identical.
