v3.4.1

What's Changed

Bug Fixes

• fix(#547): Add errata markdown-to-DuckDB indexing path — errata files in docs/errata/ are now indexed into the DuckDB errata table, closing the write-only gap where errata were created but never retrievable
• fix(#548): Fix audit-review task_group partitioning causing supersession silos — audit findings no longer use a hardcoded empty task_group, enabling proper supersession across review modes
• fix(#549): Move steering.md from .agent-fox/specs/ to .agent-fox/
• fix(#546): Fix ruff format violations in harvest warning strings
• fix(#545): Serialize AuditJsonlSink writes with threading.Lock to prevent interleaved concurrent appends

Features

• feat: ADR ingestion pipeline (spec 117) — MADR parser, validator, DuckDB migration v22 for adr_entries table, and integration into FoxKnowledgeProvider for retrieval during coder sessions

Documentation

• docs: ADR 07 — Define audit JSONL event format (envelope schema + complete event type catalog)
• docs: Code quality audit (specs 7–9)
• docs: Parking service 3.4.0 audit

Chores

Full Changelog: v3.1.3...v3.1.4

v3.1.3

What's Changed

Bug Fixes

• Budget exhaustion detection: Sessions that hit the SDK max-budget-usd limit are now detected and blocked immediately instead of being wastefully retried. The SDK returns is_error=True with no message on budget exhaustion — previously mapped to "Unknown error" and retried through the escalation ladder.
• AssessmentManager config: Pass full_config (not OrchestratorConfig) to AssessmentManager, fixing missing attribute errors.
• Escalation ladder starting tier: The escalation ladder now respects config.models.coding for the starting tier instead of always defaulting to STANDARD.
• Timed-out session metrics: Emit descriptive error messages and metrics for sessions that time out.

Features

• Knowledge system effectiveness (spec 113): Transcript reconstruction, compaction improvements, entity signal activation, cold-start handling, git extraction, audit consumption, retrieval quality validation, and audit prompt injection.

Other

• Parking service audit report
• Session budget increased for lengthy tasks

v3.1.2

Bug Fixes

• engine: Move review concurrency cap before _prepare_launch to prevent phantom retry exhaustion (fixes #503)

  The review concurrency cap in _fill_parallel_pool was checked after _prepare_launch(), which increments the attempt tracker on "allowed" verdicts. When the single review slot was occupied, audit-review tasks were skipped but their attempt counter was already incremented. After max_retries + 1 (default 3) such pool-refill cycles, the circuit breaker permanently blocked the task with "Retry limit exceeded" — without ever starting a session. This cascade-blocked all downstream coding and verifier tasks, exceeding the block budget and halting the entire run.

Recovery for affected runs

If you have a stuck run with audit-review tasks blocked by "Retry limit exceeded", clear the stale state:

agent-fox reset --spec <affected_spec_name>

Full Changelog: v3.1.1...v3.1.2

v3.1.1

Bug Fixes

• reset: clear session-scoped tables on reset to prevent block_limit death-loop (#501)

  After a block_limit run, reset --hard (and soft reset) left stale data in six session-scoped DB tables (runs, session_outcomes, review_findings, verification_results, drift_findings, blocking_history). The stale runs.status='block_limit' caused load_state_from_db() to load a terminal status, making the engine loop exit immediately on every subsequent agent-fox code invocation — a self-perpetuating death-loop with no CLI recovery path.

  All four reset paths (reset_all, reset_task, reset_spec, hard_reset_all/hard_reset_task) now clear session-scoped tables so that plan and code start from a clean state.

Full Changelog: v3.1.0...v3.1.1
