Content engine: posts that structurally cannot lie

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.
