+## Phase 9: Workspaces + capability envelope (M5)
+
+### Entry 9.1 — before
+
+- Timestamp: 2026-09-03
+- Intended action: Optional task workspace (absent / ":run" ephemeral / named persistent) and capabilities.tools allowlist (pi built-ins); runner plumbing via MOSAIC_WORKSPACE/MOSAIC_TOOLS; pi adapter maps to cwd + --tools; mock adapter logs delivered MOSAIC_* vars for deterministic assertions (Gitea #20, #21).
+- Reason: Agents that only answer text cannot do work; the workspace+tools pair is the smallest real capability step, bounded by the container.
+- Expected result: plumbing asserted via run-record stderr; live pi writes a host-visible file.
+
+### Entry 9.2 — after
+
+- Timestamp: 2026-09-03
+- Commands run: build; mock plumbing run; validate negatives; full task suite; live workspace demo.
+- Observed result: task suite 32/32; MOSAIC_WORKSPACE/MOSAIC_TOOLS asserted in run record; dataRoot/workspaces/<name> created host-side; live pi used bash to write proof.txt into the demo workspace (host-visible).
+- Failure or correction: (1) batch edit dropped SUPPORTED_TOOLS const (runtime ReferenceError, exit 1 instead of 2) — restored; (2) mock env dump used `export` which this dash prints as `export K='v'` — switched to `env`; (3) selftest fed a mismatching mock response to the plain-task case — test bug, fixed.
+
+## Phase 10: Named sessions (M6)
+
+### Entry 10.1 — before
+
+- Timestamp: 2026-09-03
+- Intended action: Optional task.session name -> persistent session dir dataRoot/sessions/<name> via pi --session-dir; resume most recent with -c when present; isolation per name; teach/recall demo fixtures (Gitea #22, #23).
+- Reason: L1 persistence is the prerequisite for any multi-step agent work.
+- Expected result: session dir populated after first run; second run recalls taught context.
+
+### Entry 10.2 — after
+
+- Timestamp: 2026-09-03
+- Commands run: build; mock plumbing run; live teach/recall E2E; task suite.
+- Observed result: task suite 32/32; teach run replied REMEMBERED and session JSONL persisted host-side; recall run resumed (-c) and answered exactly 'mosaico'; single continued session file (no duplicate sessions).
+- Failure or correction: none. Design note: ephemeral (--no-session) remains the default when no session is declared.
+
+## Phase 11: Operator ergonomics (M7)
+
+### Entry 11.1 — before
+
+- Timestamp: 2026-09-03
+- Intended action: mosaic-task.mjs show <runId> (full record + snapshots + artifacts, traversal-safe), list with workspace/session columns, RELEASE -> 0.0.6, package + health-gated activate, docs (Gitea #24).
+- Reason: Run records are only as valuable as they are inspectable; release activation closes the loop on container-content changes.
+- Expected result: show works for real/missing/traversal ids; suites green; 0.0.6 active.
+
+### Entry 11.2 — after
+
+- Timestamp: 2026-09-03
+- Commands run: build; show on real/missing/traversal ids; full sweep; release package + activate.
+- Observed result: config 24/24, task 32/32, release 14/14, verify PASS; 0.0.6 packaged and activated via exact-marker health gate.
+- Failure or correction: showRun initially rejected valid run ids (lowercase-only regex vs uppercase timestamp) and crashed on missing ids (uncaught readdir) — both fixed and covered.
