dongarandClaude Opus 5 0fd0b2e4a5 Add executor tool loop (A12/A15) — step 5b
CI / checks (push) Failing after 13s
CI / checks (pull_request) Failing after 13s
- tools.py: four flat tools (read_file, write_file, list_dir,
  run_command) per A15's reduced manifest. Deliberately unsandboxed:
  the VM is the trust boundary (B3) and tool use is auto-approved
  inside an approved unit of work (A4), so path confinement would add
  failure modes without adding safety. What is enforced is
  operational — timeout with process-group kill so a backgrounded
  server cannot outlive its command, output truncation so a build log
  cannot eat the context window, closed stdin so prompts fail fast,
  and a scrubbed environment so project code never sees the agent's
  credentials
- executor.py: renders the log, calls the executor role with the
  reduced manifest, dispatches tool calls, and checkpoints every
  result (A13). Escalation is observable, never self-assessed (A12):
  consecutive command failures and a hard turn cap. Failed reads do
  not count — looking around is not failing
- Until delegation exists (step 7), escalation gates to the human
  with the failures attached
- control.py: start milestone now runs the executor; a stopped
  milestone gates to AWAIT_INPUT

Two bugs found by running it live against real models:

- A turn-ending gate tool (submit_plan) left a tool_call with no
  tool_result, which providers reject outright, so every planning
  turn after the first failed with a 400. The planner now records the
  gate as the call's outcome, which is also the truthful transcript
- The renderer now emits a placeholder for any tool_call lacking a
  result, so a crash between call and result (A3) cannot poison the
  transcript permanently

dongarandClaude Fable 5 ac81dd6234 Add canonical event log and renderer skeleton (A10)
CI / checks (push) Successful in 9s
CI / checks (pull_request) Successful in 8s
Build-order step 4, sequenced before the LLM client (step 3) because
the client interface consumes the canonical log.

- canonical.py: typed events for the full A10 table (user_message
  through compaction); canonical tool-call IDs minted locally,
  provider IDs never a join key; strict payload validation on load
- StateStore: canonical_events table via schema v2 — the first real
  migration, exercised in a test against a hand-built v1 database —
  with append_event/read_events on the same fsync-per-commit path
- render.py: request bodies rendered from the log at call time;
  first adapter targets the OpenAI-compatible shape of LiteLLM's
  normalized route; compaction events replace their id range at
  render time while staying in the durable log
- Crash integration test now also verifies transcript appends
  survive process death
