A Claude-Code session scanner piped into domain world-state. A cheap classifier (session-signal) fans per-domain signals into four maintained truths (decisions-log, eng-backlog, use-case-guide, attention-queue) and a coalesced dashboard, so cost scales with surprise: a session moves only the domains it touches; the rest memo-skip. - 7 contracts + reactor.yml (OpenAI gpt-5.4-mini renders, gpt-5.4 compile), inline-flow static fixtures, opt-in real scanner (connectors.cjs.example), README + PIPELINE-DESIGN.md. - Committed replay/ from a captured run (11 rendered, 2 skipped, 0 failed, ~38k fresh tokens) so the reactor eval-harness is reproducible. - eval-harness: additive, env-gated Anthropic judge (JUDGE_PROVIDER=anthropic + JUDGE_MODEL, default claude-opus-4-8) via the CLI's native-Anthropic provider builder. Default OpenRouter behavior unchanged; REACTOR_OFFLINE still forces judges off. Eval result: 2/2 grade A (deterministic + opus judge).

Goal
For each changed session, classify its tail into small, typed, per-domain signals so each downstream domain wakes only when its own signal moves. This is the cheap gatekeeper of the pipeline: it does not summarize the whole session, it emits at most a one-line typed signal per domain (or nothing).
Requires
- the changed-session set from the claude-sessions gateway (each session's tail receipt: id, project, branch, and a short tail snippet)
Maintains
A set of per-session signals, split into four independently-subscribable facets so a session that carries only one kind of signal moves only that one facet. A facet is absent for a session when that session carries no signal of that kind, so an unrelated session never moves an unrelated domain. Material per signal: its session id, project, and a single short line. The fetch time, the file mtime, and the tail byte offsets are immaterial and are excluded from the fingerprint.
Postconditions: every emitted signal carries a session id and a project; a signal is emitted only when the tail actually evidences it; a session with a purely routine tail emits no signals at all.
decision-signal
Per session, a one-line decision or open question the tail evidences (a choice being weighed or made, a tradeoff, a reversal). Absent when the tail carries no decision. Subscribed to by decisions-log and attention-queue.
bug-signal
Per session, a one-line bug, failing repro, or concrete task the tail evidences. Absent when the tail carries no engineering task. Subscribed to by eng-backlog.
use-case-signal
Per session, a one-line use-case or recurring usage pattern the tail evidences (how someone is using the tool). Absent when the tail carries no use-case. Subscribed to by use-case-guide.
attention-signal
Per session, a one-line reason the session needs a human now (blocked, errored, waiting for user). Absent when the session needs nothing. Subscribed to by attention-queue.
Continuity
- input-driven: re-classify a session when its fingerprint moves in the gateway set. A session whose fingerprint did not move is skipped at zero cost.
Invariants
- This render is a bounded transform over the tail snippet already carried in the wake evidence. Read ONLY that inline tail and this node's prior world-model. Never open the session file, scan the filesystem, read the repo or node_modules, or run shell commands. Complete in a few steps.
- Classify into the four fixed signal shapes only; emit at most one short line per facet per session, and emit nothing for a facet the tail does not evidence. Do not write paragraphs, do not summarize the transcript.
- The only writable surface is this node's published world-model.
