Sun-Tzu (silent backend) — builds the strongest pro-anomaly brief the
corpus supports for any topic. Bilingual JSON: thesis + 2-4 pillars
(each with claim + citation-backed support) + honest residual
unexplained clause. NEVER surfaced reader-facing.

"Adversarial strategist who plays the pro-disclosure side with the
same rigour a red-team plays skeptic" — single thesis, 2-4 pillars,
honest residual. Every claim cites a chunk. No fabrication from
training-time knowledge. Output INTERNAL — case-writer pulls it.
Bilingual mandatory. NO_STRONG_CASE sentinel when corpus is thin.

Grounds with hybridSearch top 18 chunks, calls Sonnet, parses
JSON strict, calls writeProAnomalyBrief.
tools/write_pro_anomaly_brief.ts
Validates 2-4 pillars with bilingual claim+support, requires at
least one [[wiki-link]] citation per pillar, INSERTs.
orchestrator: new kind "anomaly_brief" dispatches Sun-Tzu.
Case-writer integration (detectives/case_writer.ts):
- Pulls most recent matching brief via ILIKE on topic or doc_id.
- Renders brief as a separate prompt section labelled
"Strategic brief (internal — do NOT cite or attribute)".
- Instructs the narrator to weave the thesis as a quiet through-
line, use pillar facts in scenes, let the unexplained clause
inform the closing paragraph. Forbidden to name "the analyst",
say "a brief argues", or use the words "thesis"/"pillar"
explicitly. Translate it into prose.
Entity hero illustrations:
- 3 painterly editorial illustrations generated via Nano Banana
Pro at 2K, stored under /data/disclosure/processing/case-art/:
* EV-1947-06-24-kenneth-arnold-sighting.png — cockpit POV of
Arnold in a CallAir A-2 over Mount Rainier, 9 chevron disc
objects in formation, 1947 Life-magazine register.
* EV-1947-07-08-roswell-incident.png — debris field in NM
desert, USAAF officer in 1947 uniform examining foil
fragments, period staff car.
* EV-1947-06-21-maury-island-incident.png — wooden patrol
boat on Puget Sound, 6 doughnut craft hovering, one
shedding glowing slag, Harold Dahl + son + dog watching.
- app/e/[cls]/[id]/page.tsx: full-bleed editorial hero replaces
the old gradient header card when an illustration exists for
that entity_id. Title sits over the painting with gradient
overlay. "Ilustração editorial" chip in the top-right.
Quota note: Claude OAuth still rate-limited as of this commit, so
Sun-Tzu hasn't been smoke-tested in production. Code is shipped and
ready; first brief will land when the weekly quota refreshes.
