# Scene 7 TODO: Prove Barricelli was an inventor

=======
Scene 7 teaches two linked ideas: a screenshot found during an OSINT search can
become source evidence, and a finding is only as useful as the report that cites
and explains that evidence.
The player opens a minimal OSINT board, reads **“Demonstrate OSINT skill: prove
Nils Aall Barricelli was an inventor,”** finds the relevant Google Patents result,
and pastes or uploads one screenshot. The board creates a document, extracts its
text, and recognizes the source. The player connects that document to the authored
Claim, completes the evidentiary statement, and files the generated Case Report.
```text
paste screenshot -> document appears -> source is verified -> connect to Claim
-> submit thin report -> provenance feedback -> accepted -> Scene 8

=======
- One suitable Google Patents screenshot is sufficient evidence, but not by itself
a complete investigation.
- Clipboard paste and file upload use the same server path.
- The image and OCR remain a real source document on the player's board.
- A known-source fuzzy match is the fast, deterministic victory path.
- A small semantic judge is a fallback for other credible sources and for
distinguishing Nils from his father. It cannot overrule the trusted path.
- Evidence about Barricelli's father may award an optional discovery but does not
clear the assignment unless it also supports the claim about Nils.
- The boarding-house fire belongs to the later age/rescue assignment, not Scene 7.
- Scene 7 records `scene7.nils_inventor_proved`. Scene 8 owns the ceremony and
awards `barricelli_luggage`.
- Inconclusive evaluation never deletes or penalizes uploaded evidence.
- Scene 7 begins with one normalized, pinned Claim exhibit: **“Nils Aall
Barricelli was an inventor.”**
- A new thread begins with **“Proof that…”**. This placeholder intentionally
produces a report that must be improved.
- An accepted source connected to the Claim can earn a qualified pass while the
report is returned for missing date/source provenance.
- The source link is encouraged but optional; date, source citation, investigator,
and a completed evidentiary statement are required.
- Story advancement requires an accepted report when the template marks its report
as required.
## Shared identifiers
| Purpose | Key |
|---|---|
| Goal | `barricelli.inventor-proof` |
| Scene 7 completion | `scene7.nils_inventor_proved` |
| Optional father discovery | `scene7.father_inventor_discovered` |
| Scene 8 reward | `barricelli_luggage` |
All identifiers and content are template data. There must be no Barricelli
conditional in React or server business logic.
## Existing foundation
- `025_level_document_flags.sql`: clonable document gates and level flags.
- `026_achievements.sql`: playthrough achievements.
- `027_evidence_text_matching.sql`: asset OCR, board match rules/anchors,
level-owned evaluations, and flag provenance.
- `028_level_goals.sql`: board-owned goals and normalized flag requirements.
- `029_semantic_evidence_judging.sql`: clonable semantic rules, level-owned
evaluations, and semantic flag provenance.
- `030_evidence_match_source_metadata.sql`: author-only canonical source metadata.
- `031_claim_case_reports.sql`: Claim exhibits, stable exhibit citations, report
configuration, immutable submissions, and normalized submission issues.
- `server/ocr.ts`: plain-text extraction and Tesseract.
- `server/evidenceMatching.ts`: OCR-tolerant fuzzy passage matching.
- `POST /api/levels/:id/documents`: persistent upload plus OCR and matching.
- The story runtime already tracks `current_node_id` and `current_level_id`.
## Architecture contract
### Recognition and completion are separate
Recognition answers what a document supports. A goal answers whether the level's
authored requirements have been satisfied. `level_goals` and
`level_goal_flag_requirements` clone with a template. Goal completion is derived
from level flags; there is no second mutable completion boolean.
Play mode receives a goal's key, title, instructions, completion copy, status,
and completion time. IDs, enabled state, required flags, target text, and judging
prompts remain author-only.
### Known-source fast path
The Scene 7 template owns an `evidence_match_rule` with distinctive text visible
in the real Google Patents result: a combination of patent number/title, inventor
name, and invention language. A name alone is too generic. When enough anchors
match, the existing matcher awards `scene7.nils_inventor_proved` in the upload
transaction and the goal becomes complete immediately.
Reference OCR, thresholds, source metadata, and copy live in the manifest/database,
not TypeScript constants. The expected text is never returned to play mode.
### Semantic fallback
A provider-neutral `EvidenceJudge` receives only allowlisted goal data and OCR
text. It returns strictly validated structured data:
```ts
type EvidenceVerdict = {
subject: 'target' | 'related' | 'ambiguous' | 'neither'
supportsClaim: boolean
evidenceExcerpt: string
confidence: number
}

`newlyCompleted` is response-local: a reload returns complete with
`newlyCompleted: false`.
## Security and cost limits
- Require identity and level ownership on player mutations.
- Limit upload bytes, OCR/model characters, output tokens, duration, and retries.
- Never expose reference anchors or judge instructions to play mode.
- Treat filenames, MIME declarations, OCR, and model output as untrusted.
- Validate model output and confidence before mutating flags.
- Persist enough provenance to explain completion without storing unnecessary raw
provider payloads.
## Out of scope
- Scenes 16, Scene 8's ceremony/3D model, and Scene 9's fire mystery.
- Knowledge graph, general-purpose claim ontology, or multi-document synthesis.
- Web crawling, URL fetching, or requiring a URL for victory.
- Custom model training or the general story graph `llm_gate`.
- Deleting irrelevant evidence.
## Merge guidance
Prefer new modules and narrow glue commits. High-conflict files are
`server/index.ts`, `server/narrativeRepository.ts`, `src/App.tsx`, `src/main.tsx`,
and `src/play.tsx`; one integrator should own their final changes.
Suggested order: S7-A schema -> S7-B deterministic content -> S7-C judge -> S7-D
story bridge -> S7-E UI -> S7-F hardening. Reserve migration numbers before
parallel schema work and never renumber an already-shared migration silently.
## Definition of done
From a fresh playthrough, the player reaches Scene 7 and sees one authored Claim.
They paste one accepted Google Patents screenshot, connect Exhibit 1 to the Claim,
and see **“Proof that…”** appear in the typewriter report. The first thin submission
passes the evidence but is returned for provenance; adding the date, source citation,
and a proper evidentiary statement produces an accepted report and enables Continue.
