Explicit per-stage grants (least-privilege, invariant #5) for the mounted
codebase-memory MCP side-car:
- role_pipeline: discovery bootstraps the graph (index_repository) + grounds;
analyst/architect/decomposer/implementer/reviewer get read-only query tools
(search_code/search_graph/get_architecture/trace_path/get_code_snippet)
scoped to each role. NOTE: architect flips from pure-reasoning to tool-calling.
- review_loop implement+review and task_planning planner get read-only queries.
Tools are approval-gated at T2 (server default in config.toml [[mcp]]).

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.
Two orchestrator tool-gating behaviors (both touch SessionOrchestrator):
- Read-only switch: when a tool call is BLOCKed with READ_BEFORE_WRITE, derive a
read-only mode from the event log (block until a later FILE_READ completes) and
withhold FILE_WRITE tools from the next inference turn(s), so a weak model is
pushed down the read-then-write path instead of looping on the blocked write.
- require_task_decompose stage flag (TomlWorkflowLoader) + owesTaskDecompose guard:
a stage so marked cannot stage_complete until a task_decompose/task_create has
succeeded this stage. New task_planning workflow + prompt are the first consumer
(decompose-only: swoop codebase, emit a parent + DEPENDS_ON task graph, stop).
