Uncommitted work from the session-robustness-and-dox branch sweep
(docs/qa/QA-session-robustness-and-dox.md), verified alongside the
compression/context fixes:
- SandboxedToolExecutor: validate tool args centrally before dispatch. A
malformed/missing-arg call becomes a recoverable ERROR: (surfaced with the
tool's arg schema so the model can correct + retry) instead of stranding
the stage with no artifact. + validation test.
- PlanLinter: seed artifacts (analysis) produced by the planning phase count
as available producers, so a plan stage that `needs` them isn't flagged as
an unproduced-need; H1 unproduced-needs + trap-state checks. + tests.
- DefaultSessionOrchestrator: live-QA robustness fixes (event-tail /
per-stage budget + retry handling).
- workflow prompts/configs: DOX AGENTS.md alignment + freestyle/task/role
prompt tweaks.
- SessionOrchestratorIntegrationTest: coverage for the above.
- FreestylePlanningWorkflowTest: allow list_dir in analyst tools (follows the
list_dir wiring in 968cbfa).
- QA plan doc for the branch sweep.
