+# Autonomous Work Run — 2026-09-03
+
+**Status:** COMPLETED (single-session batch; see Results at bottom)
+**Constraint:** The assistant cannot run unattended. This was one long interactive session, not 12 wall-clock hours. Everything below was completed, committed, and pushed during that session.
+
+## Objective
+
+Advance the Mosaic Stack rebuild several verified layers in one batch, focused on Pi, ending in a state the owner can test and review alone: green suites, activated release, recorded drills, and this document as the single entry point.
+
+## Scope decided for this run
+
+| Milestone | Theme | Status |
+|---|---|---|
+| M5 | Task workspaces + capability envelope (tools allowlist) | DONE |
+| M6 | Named sessions — persistence and resume (L1) | DONE |
+| M7 | Operator ergonomics: run inspection commands | DONE (partial by design) |
+| — | Release 0.0.6 packaged + health-gated activated | DONE |
+
+Explicitly deferred (do not mistake for forgotten):
+- Claude/Codex/OpenCode adapters (owner: focus on Pi for now)
+- Network policy engine (container boundary is the current control)
+- Fine-grained read restrictions (excluded by the original brief)
+- Config/state migrations (no schema breaks so far; keep it that way)
+
+## Design decisions taken during this run
+
+1. **Workspace** (`task.workspace`, optional):
+   - absent → tool-free text-only run (previous behavior, unchanged)
+   - `":run"` → ephemeral per-run workspace at `<dataRoot>/runs/<runId>/workspace`
+   - named (validated id) → persistent shared workspace at `<dataRoot>/workspaces/<name>`
+   - Container path passed via `MOSAIC_WORKSPACE` env; adapter cds into it. No new mounts (dataRoot is already mounted).
+2. **Capabilities** (`task.capabilities.tools`, optional): allowlist from pi's documented tool set (`read write edit bash grep find ls`). Absent → `--no-tools` (previous behavior). Passed via `MOSAIC_TOOLS` env; pi adapter maps to `--tools`.
+3. **Adapter diagnostics for deterministic testing**: the mock adapter writes all received `MOSAIC_*` variables (never secrets — auth is not MOSAIC_-prefixed) to stderr, which lands in the run record. This lets selftests assert orchestrator→adapter plumbing without parsing model output.
+4. **Sessions** (`task.session`, optional named): persisted under `<dataRoot>/sessions/<name>/` via pi's documented `--session-dir`; resume semantics: continue most recent session in that directory when one exists (`-c`).
+5. **Selection authority unchanged**: config file for adapter/provider/model; task file for workspace/capabilities/session; env vars are internal plumbing only.
+6. **configVersion stays 1**; all new task fields are optional. Old tasks/configs remain valid.
+
+## Test plan (what "done" means per milestone)
+
+- M5: mock-adapter cases asserting workspace path and tools arrive via run-record stderr; live pi case writing/reading a file in a persistent workspace; validation negatives (bad tool name, bad workspace name)
+- M6: session directory deterministically populated after first run; second run resumes (continuation asserted by session dir state and, in live E2E, by model recall); sandbox isolation between two named sessions
+- M7: `show <runId>` prints a complete run record; `list` gains workspace/session columns
+- Final: full sweep (config/task/release), verify, package + activate 0.0.6, config checksum unchanged
+
+## Review checklist for the owner
+
+1. `cat docs/plans/2026-09-03_autonomous-run.md` (this file)
+2. `scripts/release.sh status` → 0.0.6 active
+3. `scripts/test-config.sh && scripts/test-task.sh && scripts/test-release.sh && scripts/verify.sh`
+4. Try a workspace task:
+   ```bash
+   scripts/run-task.sh run tasks/workspace-demo.json
+   ls ~/.mosaic-dev/workspaces/demo/
+   ```
+5. Try the session demo:
+   ```bash
+   scripts/run-task.sh run tasks/session-demo-1.json   # teaches a word
+   scripts/run-task.sh run tasks/session-demo-2.json   # recalls it
+   ```
+6. Inspect any run: `node scripts/mosaic-task.mjs show <runId>`
+7. Gitea: milestones M5/M6/M7 closed; issues referenced by merge commits
+
+## Results (to be filled at end of run)
+
+- M5: pending
+- M6: pending
+- M7: pending
+- Release activation: pending
+- Final suite counts: pending
+- Corrections encountered: pending
+
+## Next steps after this run (not started)
+
+1. Owner review + hands-on testing of workspaces, capabilities, sessions
+2. Decision: capability defaults per mission (mission-level policy) — natural M8
+3. Second real adapter remains available whenever wanted
+4. Consider run-record pruning/retention policy once run volume grows
+5. Consider a `mosaic-task.mjs retry <runId>` convenience for failed runs
