Module signals 

Decision signals: timestamped supersede / binding-conflict markers recorded at edda decide time, counted back by session window at postmortem time.

Why: the two natural High-severity postmortem paths (decision reversal, multi-agent conflict) starved because their inputs were hardcoded to 0/false at the SessionEnd wiring (flywheel drill 1 finding). The CLI already detects both cases when a decide lands — this module just gives those detections a durable, windowable trace.

Storage: <project state>/decision_signals.jsonl, append-only, one JSON object per line: {"ts": "<rfc3339>", "kind": "superseded"|"binding_conflict", "key": "<decision key>"}. Recording is best-effort — a failed append must never block a decide.

Structs

SignalCounts

Windowed counts consumed by the postmortem wiring.

Enums

SignalKind

What the decide path observed.

Functions

count_signals_at

Windowed count against an explicit file path (testable core).

count_signals_between

Count signals for project_id whose ts falls inside [first_ts, last_ts]. None bounds are open-ended. Missing file ⇒ zeros; malformed lines skipped.

record_conflict_if_cross_actor

Record a binding_conflict signal only when the two actors differ. Wraps record_signal_at for the tested path (病一 治法).

record_conflict_signal_if_cross_actor

Same as record_conflict_if_cross_actor but resolves the project’s signals file.

record_decision_signal

Append one signal for project_id (creates parent dirs on first use).

record_signal_at

Append one signal to an explicit file path (testable core).

should_record_conflict

SELECTOR3 病一:conflict 訊號的自/他區分。 同 actor(session 進版自己的 binding)=不記 conflict;異 actor=真跨 agent 衝突,記。 superseded 訊號不經此路——那是判斷含量的正貨,自/他都要記。

signals_path

Signals file for a project (lives next to lessons/rules state).
