 340. **Resume-safe `/session help --output-format json` writes its primary JSON error envelope to stderr and uses `type` instead of the session JSON `kind` vocabulary** — dogfooded 2026-04-29 on current `origin/main` / rebuilt `./rust/target/debug/claw` with embedded `git_sha` `dc47482e`. Running `./rust/target/debug/claw --resume latest /session help --output-format json` wrote no stdout bytes, but wrote a JSON error object to stderr: `{"command":"/session help","error":"Unknown /session action ...","type":"error"}`. Meanwhile `/session list --output-format json` wrote valid stdout JSON with `kind=session_list`. The JSON output contract is therefore split across stderr for an error/help-ish action and switches vocabulary from `kind` to `type`; automation that reads stdout sees empty/non-JSON output and cannot handle errors consistently with successful session JSON responses. **Required fix shape:** (a) all `--output-format json` command responses, including resumed slash errors, should emit the primary JSON envelope on stdout; (b) use `kind:"error"` or a documented error schema consistently instead of an ad hoc `type` field; (c) reserve stderr prose for text mode or optional non-primary diagnostics, not the machine-readable envelope; (d) add a regression for `/session help` or an unsupported `/session` action under `--resume` proving stdout contains the structured JSON error envelope and stderr does not carry the only parseable payload. **Why this matters:** claws need one stdout JSON contract for both success and failure. If a help-ish session error is silently moved to stderr and shaped differently from `session_list`, orchestration lanes cannot distinguish an unsupported action from transport corruption or an empty response without bespoke stderr parsing.

 341. **Resume-safe `/tasks --output-format json` emits an unsupported-command JSON error only on stderr and mixes `kind` with `type` classification vocabularies** — dogfooded 2026-04-29 for the 16:00 nudge on current `origin/main` / rebuilt `./rust/target/debug/claw` with embedded `git_sha` `58569131`. Running `./rust/target/debug/claw --resume latest /tasks --output-format json` wrote no stdout bytes, but wrote a JSON error object to stderr: `{"command":"/tasks","error":"/tasks is not yet implemented in this build","kind":"unsupported_command","type":"error"}`. The unsupported command envelope therefore has two separate top-level classification vocabularies (`kind=unsupported_command` and `type=error`) and places the only parseable payload on stderr, while successful JSON commands use stdout and a `kind`-only classification. This is distinct from #340 because it is not session help; it shows implemented-but-unsupported command stubs can emit a dual-vocabulary error envelope. **Required fix shape:** (a) in `--output-format json` mode, emit the primary JSON envelope on stdout for unsupported resumed slash commands such as `/tasks`; (b) document and use one error discriminator, preferably `kind:"error"` plus `code:"unsupported_command"`, or `kind:"unsupported_command"` plus `status:"error"`, but not `type`; (c) reserve stderr for non-primary diagnostics or text-mode prose, never as the sole JSON payload; (d) add regression coverage for `/tasks` under `--resume` with JSON output proving stdout contains the structured error envelope, stderr is not the only parseable stream, and the envelope uses the documented single-vocabulary discriminator. **Why this matters:** claws need the same stdout JSON contract for implemented successes and implemented-but-unsupported stubs. If `/tasks` errors can silently move to stderr and advertise both `kind` and `type`, automation must special-case command stubs instead of applying one JSON error parser.

+345. **`claw status --output-format json` and `/status --output-format json` do not include the active session ID in the JSON output, and `workspace.session_id` is always `null` even when resumed with `--resume latest`** — dogfooded 2026-04-30 by Jobdori on `5856913`. Running `claw --output-format json --resume latest /status` returns `workspace.session_id: null` and `workspace.session: "live-repl"` — impossible to confirm which session is active from `status` output alone. Also `workspace.changed_files: 3` while `staged_files: 0, unstaged_files: 0, untracked_files: 3` — if `changed_files` counts only tracked changes it should be 0; if it counts everything it duplicates `untracked_files`. Counter semantics are ambiguous. **Fix:** populate `workspace.session_id` when resumed; clarify `changed_files` vs `staged+unstaged+untracked` counter semantics.
