Priority Board Triage

When to Use

• Changing the risk model, the evidence bundle, the review prompt or its validation.
• Adding a writer of any triage_* property: a run step, a route, an MCP tool, a migration.
• Adding a reader of the board state: a report, an MCP tool, a filter, a UI chip.

For the Cypher itself, also follow graph-db-writes; for a new MCP tool, mcp-server-tools.

Critical Rules

• NOBODY writes a final score. triage_priority_score, triage_tier, triage_tier_rule, triage_risk, triage_factors, triage_state and triage_decided_by (the mixin's _FINAL_SET) come ONLY from score_model.combine_layers(), reached through layers.combine_props(). A writer changes ITS layer and asks combine for the final inside the same transaction. Setting a final directly is how a review or a verdict used to vanish at the next run.

• Each writer touches one layer.

  Writer	Layer	Method
  a run's publish	BASE (+ a builtin REVIEW it made)	publish_triage_layers
  an MCP agent's review	REVIEW, channel mcp	write_review
  a person (app, or MCP with channel mcp)	DECISION	set_human_verdict

  A publish never writes a decision, :Muted or updated_at; a review never writes a decision or the base; a verdict never writes the base or a review.

• NEVER write updated_at from triage. It is the scan's "last seen" stamp: the prune reads it, and the publish's guard skips a node whose updated_at moved since the run read it. A triage write that bumped it would make every finding look re-ingested.

• Every single-finding write is lock-then-read, in one managed transaction. SET n._triage_lock = true REMOVE n._triage_lock first, then read the node, the live proof (_LIVE_PROOF) and the current layers, then decide and write. Match exactly one node, else ambiguous. A timeout raises TriageWriteBusy, which the API returns as 503 busy. Never read proof from a run's snapshot.

• Live proof is proof of THIS finding. _LIVE_PROOF mirrors score_model.is_proven; it must not read triage_proof, which records proof on the finding's HOST. Reading it lifted every finding on a compromised host to T1 "proven" at its next rescore. (The mute guards' _PROVEN does read it, on purpose: refusing a mute on a compromised host is the safe direction.)

• An app decision is never changed or reset over MCP (decided_in_app). Only app-channel decisions by the user themself teach a detector's prior.

• A review is valid only while triage_ai_evidence_hash == triage_evidence_hash. The hash is bundle_hash(build_bundle(...)): normalised, secret-redacted, capped. Changing the bundle, the redaction or the cap changes every hash and expires every review: bump REVIEW_PROMPT_VERSION deliberately, never by accident.

• A run never reviews over a valid mcp review, and re-reviews its own (builtin) only on a model or prompt-version change. Fix-item text (fix_lever, ai_quote) comes from builtin reviews only.

• Keep the legacy readers tolerant. Unknown or legacy values mean "no layer", never a decision. triage_source = 'ai' is a builtin false-positive review; a missing triage_verdict_channel means app. The first publish after an upgrade adopts an unchanged review-v1 review through build_bundle_legacy, and unmute applies the same cleanup to muted nodes. Readers that branch on this: score_model.finding_state, reportData.ts, projectRisk.ts, tooling/scripts/triage_eval.py.

• A new stored triage_* property goes in TRIAGE_PROPS (triage_mixin.py), which feeds triage_graph_migrate.py, and in TRIAGE_PROPERTIES (webapp/src/lib/triage/properties.ts), which keeps it out of the Recon Delta. Agent-writable text also goes in TRIAGE_TEXT_PROPERTIES, so buildNodeContext never hands it to the in-app agent. Declare it in graph_db/schema_sections.md and re-seed the catalog.

Pattern: a writer asks combine for the final

pythonCopy code
# graph_db/mixins/recon/triage_mixin.py - write_review, trimmed
def work(tx):
    found = self._lock_findings(tx, user_id, project_id, node_id, label)  # lock, THEN read
    ...                                                  # not_found / ambiguous
    props = dict(rec["props"])
    outcome = decide(props, rec["proven_now"], rec["updated_at"], rec["label"])
    if outcome.get("refused"):
        return {"written": False, "reason": outcome["refused"]}   # nothing written
    review = self._clean_review(outcome["review"])       # only THIS layer's keys
    tx.run("MATCH (n) WHERE elementId(n) = $eid SET n += $review", ...)
    props.update(review)
    final = self._clean_final(combine(props, rec["proven_now"]))  # layers.combine_props
    tx.run(f"MATCH (n) WHERE elementId(n) = $eid SET {self._FINAL_SET}", ...)
return self._write_tx(self.driver, work, timeout)       # TriageWriteBusy on timeout
