Normalise and length-check ledger fields in db.RecordCoverage, frame the planner gap lines in the data envelope, cap the wrap-up (25) and report (200) gap lists, cap current rows at 2000 per task. Replace the activity budget marker with tasks.end_reason, written with the guarded terminal status and cleared on revive. Generic 500 message in taskCoverage; early return on an empty ledger in the planner block.
Per-level token/turn budgets: task -> intent (worker run) -> planner round
(counted inside the task). A child's effective budget is
min(own budget, parent's remaining above the wrap-up reserve). When the task
can no longer afford one worker, workers stop claiming intents and the task
settles through one forced wrap-up planner round (the existing settle
sequence, budget words instead of the timeout words).
Config: ARTEX_TASK_BUDGET_TOKENS, ARTEX_TASK_BUDGET_TURNS,
ARTEX_INTENT_BUDGET_TOKENS, ARTEX_INTENT_BUDGET_TURNS. 0 or unset = unlimited;
with all four unset nothing changes.
Step 1.1 of the S3b phase 1 plan. Wiring only: the approval gate for asset
targets is not enforced yet and no behaviour changes.
- Planner.Plan and MainAgent.Chat take a hooks parameter, like Worker.Execute.
Their sessions had no hooks, so nothing saw their tool calls before execution.
- guard.NewTargetOnly: the guard for those two agent kinds. It runs the
target-gate seam only: no intercept rule, no fallback judge, and no entry in
the audit ring (Guard.record is untouched and not called for these calls).
- Task.TargetGuard, built beside Task.Guard.
- intercept.WithTargetScope / TargetScopeFromContext: task id or conversation
id, an Enabled func and a wait bound, set at the five session entry points
(planner round, final planner round with wait bound 0, main-agent turn,
worker intent, conversation turn).
The seam allows every call and reads and writes nothing. No task or
conversation has an opt-in flag yet, so Enabled is nil (off) everywhere.
An intent claim was atomic but had no heartbeat, no expiry and no owner
token: startup reset every running intent to open unconditionally, so a
second instance on the same database stole live claims, and the worker
that lost its intent could still write the result.
- schema: last_heartbeat_at and unclaim_token on exploration_nodes
(idempotent ADD COLUMN IF NOT EXISTS, nullable, no CHECK, no backfill).
- db: every claim (open->running and the paused->running message path)
gets a fresh crypto/rand token and starts its lease in the same UPDATE.
HeartbeatIntentClaim renews it for that token only.
- TTL: db.IntentClaimTTL = 90s, heartbeat every 15s
(db.IntentClaimHeartbeatInterval), both on the database clock.
- takeover: ResetRunningIntents now reopens only claims whose heartbeat
is older than the TTL, or NULL (rows claimed before the columns
existed). The engine runs it per task every 15s as well as at startup.
- fencing: a heartbeat or result write whose token is not the current
one returns db.ErrIntentClaimLost and writes nothing. All intent state
writes in runIntent go through the fenced SettleIntentClaim /
SettleIntentClaimBlocked; a rejected heartbeat cancels the stale run
with the new work_claim_lost cause.
Behaviour change: after a restart, intents that were in flight are
resumed once their claim expires (at most 105s) instead of immediately.
Not in this change: fencing of the facts, findings and activity a worker
writes during its run; they are not guarded by the token.
Implements the per-intent rotation shape from #85: a task created with
llm_rotate=true distributes worker intents round-robin over its LLM chain
heads, so lane A can hunt on one model while lane B hunts on another
(different lenses per intent, no extra tokens). Default stays the classic
ordered failover from the active head; planner/goals/mainagent keep the
active head always.
Mechanics: the engine pins the next chain head into the run context when a
worker claims an intent; the pin travels through the provider resolver
(hooks.current now takes ctx). A pin is only a dispatch preference - it must
belong to the task chain and never bypasses failover state (an exhausted
chain stays exhausted). Schema: tasks.llm_rotate boolean, default false,
idempotent ALTER; exposed on the create payload and the task DTO.
Closes#85 (the ensemble/P4 shape stays parked as before)
Quiet-mode was compile-time only; wanting it off mid-task (empty frontier, one long intent, idle lanes) was impossible. tasks.plan_quiet_mode (default on) gates the edge-round skip in runRound, PATCH /api/tasks/{id} flips it live (the next round reads it), creation accepts plan_quiet_mode, and the DTO exposes it.
Every worker write-back fired a full planning round even when the open-goal set had not changed; on a live three-worker task that was 7 rounds in 45 minutes. Edge-triggered rounds are now dropped while active intents exist and the open-goal fingerprint recorded at the end of the last round is unchanged; heartbeat rounds, goal-set changes and frontier drains still plan immediately. Fails open on store errors.
Comments, doc comments, UI labels, log and error messages, LLM prompt
strings, markdown docs, test data and assertions. Identifiers, enum
keys, routes, placeholders and code structure are unchanged.
Notes:
- docs/漏洞流量证据.md renamed to docs/vulnerability-traffic-evidence.md
- tests that exercised CJK specific handling (GBK zip names, Chinese
full text search) now use ASCII equivalents; go build passes and the
test suite matches the pre translation baseline (remaining failures
need a PostgreSQL DSN and fail identically on the original)
- frontend mention syntax now uses English kinds (finding, asset, ...)
matching the backend, chat mentions tests pass
