 323. **`status --output-format json` reports `session.session = "live-repl"` while simultaneously reporting `session_lifecycle.kind = "saved_only"` — contradictory session identity in a single status snapshot** — dogfooded 2026-04-29 by Jobdori on current main (`804d96b`). Running `claw status --output-format json` from an active REPL-style invocation produced `"session": "live-repl"` in the `workspace` block and `"session_lifecycle": {"kind": "saved_only", "pane_id": null, ...}` in the same object. Those two fields carry contradictory claims: `"live-repl"` asserts there is an active interactive session, while `"saved_only"` asserts there is no live tmux pane hosting the session — the session exists only as a saved artifact. A downstream claw reading this snapshot cannot tell which claim to trust: is this a running session whose pane is undetectable, or a saved-only session that the `session` field is misclassifying? Root cause: `"live-repl"` is a fallback sentinel emitted by `main.rs:6070` when `context.session_path` is `None`, while `session_lifecycle` is computed independently by `classify_session_lifecycle_for()` from tmux pane discovery; the two fields share no common source and can diverge. **Required fix shape:** (a) derive both `session.session` and `session_lifecycle.kind` from the same lifecycle classification result so they cannot diverge; (b) replace the `"live-repl"` free-form sentinel with a structured `session_kind` field (`live_repl`, `saved`, `resume`, etc.) that carries the same type vocabulary as `session_lifecycle.kind`; (c) when `session_lifecycle.kind = "saved_only"`, never emit `"session": "live-repl"` (or vice versa); (d) add a regression test proving `status --output-format json` never emits `session.kind = "live_repl"` and `session_lifecycle.kind = "saved_only"` simultaneously. **Why this matters:** `status --output-format json` is the machine-readable truth surface for session state; if two fields in the same snapshot contradict each other, every lane, monitor, and orchestrator has to pick a winner instead of reading a coherent state.

-324. **Stale local debug binaries can impersonate the current workspace because version/status/doctor do not compare embedded build provenance to repo HEAD** — dogfooded 2026-04-29 on current `origin/main` / workspace HEAD `e7074f47` after PR #2838. The working tree was at `e7074f47`, but running `./rust/target/debug/claw version --output-format json` reported embedded `git_sha` `1f901988`. `status` and `doctor` remained green and exposed no warning that the executable under test was stale relative to the workspace HEAD, nor any structured build-provenance freshness signal that downstream claws could use to decide whether the observed behavior came from the checked-out code or an older debug artifact. This is a repo-identity opacity gap: the JSON truth surfaces can look authoritative while actually describing a different binary lineage than the source tree being dogfooded. **Required fix shape:** (a) compare the embedded build `git_sha` / build date with the current workspace git HEAD and dirty state when the binary can discover a containing worktree; (b) expose redaction-safe structured fields in `version --output-format json`, `status --output-format json`, and `doctor --output-format json`, including `binary_provenance`, `workspace_head`, and `stale_binary` (with enough reason/detail to distinguish clean match, dirty workspace, unknown workspace, and definite stale SHA mismatch); (c) warn in human/text mode when executing a stale local debug binary such as `./rust/target/debug/claw` so dogfooders do not trust old behavior as current-main evidence; (d) avoid leaking secrets or absolute sensitive paths beyond the existing workspace-identification policy; (e) add regression/fixture coverage for matching HEAD, dirty workspace, no-worktree/unknown provenance, and stale embedded SHA cases. **Why this matters:** status/doctor/version are supposed to be the machine-readable basis for dogfood truth. If a stale binary can report a different `git_sha` than the checked-out repo without any freshness warning, claws can file or verify bugs against the wrong code and waste cycles chasing already-fixed or not-yet-built behavior. Source: gaebal-gajae dogfood follow-up from current main `e7074f47` after PR #2838; observed `./rust/target/debug/claw version --output-format json` reporting `git_sha` `1f901988` with no stale-binary-vs-workspace-HEAD warning.

-325. **`help --output-format json` returns valid JSON but hides the actual help schema inside one prose `message` string** — dogfooded 2026-04-29 on current `origin/main` / workspace HEAD `d607ff36`. Running `./rust/target/debug/claw help --output-format json` produces parseable JSON, but the object only exposes top-level keys like `kind` and `message`; all command names, global flags, slash-command metadata, aliases, resume-safety, output-format support, auth/preflight notes, and descriptions are flattened into one human-oriented prose blob. That technically satisfies “valid JSON” while still forcing automation to scrape the same help text humans read, making `/issue`, `/help`, and resume-safety contracts opaque to claws. **Required fix shape:** (a) keep `message` as the compact human-rendered help summary, but add a documented structured schema with `schema` / `schema_version` fields; (b) expose first-class arrays/objects such as `commands[]`, `options[]`, and `slash_commands[]` with stable fields including `name`, `aliases`, `description`, `args`, `output_formats_supported`, `resume_safe`, `interactive_only`, and `creates_external_side_effects`; (c) include auth and creation preflight metadata where relevant, especially for GitHub/issue flows (`auth_preflight`, `creation_unavailable`, `gh_cli_authenticated`, `github_token_present`, or equivalent non-secret state); (d) make `/issue`, `/help`, aliases, and resume-dispatch safety machine-readable from the JSON payload instead of recoverable only by parsing prose markers; (e) add regression coverage proving `help --output-format json` is valid JSON and that `/issue`, `/help`, resume-safe vs interactive-only slash commands, aliases, descriptions, supported output formats, and side-effect/auth-preflight fields are present and internally consistent. **Why this matters:** help JSON is the discoverability surface automation uses before invoking commands. If it is just prose wrapped in JSON, claws cannot safely decide whether a command can run non-interactively, resume from a saved session, create external GitHub side effects, or requires auth/preflight without brittle text scraping. Source: gaebal-gajae dogfood follow-up from current main `d607ff36`; observed `./rust/target/debug/claw help --output-format json` returning valid JSON with only `{kind,message}` at the top level while the actionable command schema remained buried in `message`.

-326. **`status --output-format json` underreports active workspace pane inventory when one tmux session has multiple panes/processes in the same project** — dogfooded 2026-04-29 on current `origin/main` / workspace HEAD `b90875fa` while responding to the claw-code dogfood nudge. The active OMX session `claw-code-issue-326-dogfood-pinpoint` was running in `/mnt/offloading/Workspace/claw-code` with two panes: `%9384` (`cmd=node`, active pane) and `%9385` (`cmd=node`, inactive sidecar pane). `tmux list-panes -a -F '#{session_name}:#{window_index}.#{pane_index} #{pane_id} pid=#{pane_pid} cmd=#{pane_current_command} cwd=#{pane_current_path} active=#{pane_active}'` showed both panes in the same session/workspace, but `./rust/target/debug/claw status --output-format json` collapsed the workspace lifecycle to a single object: `session_lifecycle.kind = "running_process"`, `pane_id = "%9384"`, `pane_command = "node"`, with no `panes[]`, process count, sidecar/secondary-pane inventory, or ambiguity marker. A downstream claw reading only status JSON would believe there is exactly one live process for that workspace even though the control plane has multiple panes in the same task session. **Required fix shape:** (a) expose a structured active-session inventory in `status --output-format json`, including `panes[]` or `processes[]` with pane id, command, cwd, active flag, and session/window identity for all matching workspace panes; (b) keep the compact `session_lifecycle` summary, but add an explicit `pane_count` / `has_sidecar_panes` / `inventory_truncated` signal so summaries cannot masquerade as complete truth; (c) define how to classify primary vs sidecar/inactive panes without losing them, and make the chosen primary pane provenance visible; (d) add regression coverage for a tmux session with two panes in one workspace proving status JSON reports both panes or marks the inventory as partial. **Why this matters:** status JSON is the machine-readable lane truth surface. If it reports only the primary pane while hiding secondary panes, clawhip and other claws can miss sidecar workers, blocked helpers, stale subprocesses, or duplicated control-plane processes and make bad restart/cleanup/routing decisions from an undercounted session snapshot. Source: gaebal-gajae dogfood session `claw-code-issue-326-dogfood-pinpoint`; observed `claw status --output-format json` returning only `%9384` while `tmux list-panes` showed `%9384` and `%9385` in the same claw-code workspace.

-327. **`claw mcp help` omits `.claw.json` from its documented config sources even though `claw mcp` still loads MCP servers from `.claw.json`** — dogfooded 2026-04-29 on current `origin/main` / workspace HEAD `981aff7c` after rebuilding the actual debug binary with `cargo run --manifest-path rust/Cargo.toml --bin claw -- version --output-format json` so `./rust/target/debug/claw version --output-format json` reported embedded `git_sha` `981aff7c` matching the workspace. Running `./rust/target/debug/claw mcp --help` printed `Sources          .claw/settings.json, .claw/settings.local.json`, and `./rust/target/debug/claw mcp help --output-format json` returned `"sources": [".claw/settings.json", ".claw/settings.local.json"]`. In the same rebuilt binary, a temp workspace containing only a project `.claw.json` with `{"mcpServers":{"demo":{"command":"/bin/echo","args":["hi"]}}}` made `./rust/target/debug/claw mcp --output-format json` report `configured_servers: 1` and `servers[0].name: "demo"`. The MCP lifecycle surface therefore tells users and claws that `.claw.json` is not a source while actively accepting it as one. This is distinct from #322's JSON warning corruption, #323/#326's status lifecycle contradictions, #324's stale-binary provenance gap, and #325's top-level help schema flattening: the pinpoint is a concrete MCP subcommand source-of-truth mismatch in both text and JSON help. **Required fix shape:** (a) derive the `mcp help` source list from the same `ConfigLoader::discover`/settings-source registry that `mcp list` actually uses instead of hard-coding a partial list; (b) include all supported MCP config sources in stable order, including legacy/project `.claw.json`, user `~/.claw/settings.json`, project `.claw/settings.json`, and local `.claw/settings.local.json` as applicable; (c) add source metadata to `mcp --output-format json` entries so each server can be attributed to the file/layer that provided it; (d) add a regression proving a server loaded from `.claw.json` is accompanied by help/JSON source metadata that names `.claw.json`, and that help stays in sync when config source discovery changes. **Why this matters:** MCP setup is already a high-friction lifecycle path; if the command that diagnoses MCP servers omits a still-supported source, operators can move or delete the wrong config file, and automation cannot tell whether `.claw.json` support is intentional compatibility or accidental legacy behavior. Source: gaebal-gajae dogfood in `/home/bellman/Workspace/claw-code` on 2026-04-29 using the rebuilt actual `./rust/target/debug/claw`; temp-workspace proof showed `.claw.json` loads one MCP server while `mcp help` documents only `.claw/settings*.json` sources.

-328. **`claw agents help` omits the `.codex/agents` roots that `claw agents` actually loads from, so native-agent discovery provenance is misleading** — dogfooded 2026-04-29 on current `origin/main` / workspace HEAD `ee85fed6` after rebuilding the actual debug binary with `cargo run --manifest-path rust/Cargo.toml --bin claw -- version --output-format json`; `./rust/target/debug/claw version --output-format json` then reported embedded `git_sha` `ee85fed6`, matching the workspace. Running `./rust/target/debug/claw agents help --output-format json` returned `usage.sources = [".claw/agents", "~/.claw/agents", "$CLAW_CONFIG_HOME/agents"]`, with no `.codex/agents` or `~/.codex/agents` entry. In the same environment, `./rust/target/debug/claw agents --output-format json` listed native agents such as `analyst` with source `{id: "user_claw", label: "User home roots"}` even though `/home/bellman/.claw/agents` does not exist and `/home/bellman/.codex/agents/analyst.toml` does exist. The agents lifecycle surface therefore documents one set of roots while loading from another, and the loaded-agent provenance collapses the real Codex root behind a generic `user_claw` label. This is distinct from #327's MCP source-list mismatch: the affected subsystem is native-agent discovery, where claws choose delegation/staffing lanes from `claw agents` and need to know which root supplied each agent. **Required fix shape:** (a) derive `agents help` source roots from the same registry/search path used by the agent loader instead of a hard-coded `.claw`-only list; (b) include all supported native-agent roots in stable order, including project/user `.codex/agents` roots alongside `.claw/agents` and `$CLAW_CONFIG_HOME/agents`; (c) make each `agents --output-format json` entry expose non-secret source provenance precise enough to distinguish `user_codex`, `project_codex`, `user_claw`, and `project_claw` (without leaking unnecessary absolute paths); (d) add a regression proving an agent loaded from `~/.codex/agents` is accompanied by help-source metadata naming that root and per-agent provenance that does not mislabel it as generic `user_claw`. **Why this matters:** agent selection is a control-plane decision. If help says only `.claw/agents` are searched while the runtime actually consumes `.codex/agents`, claws and operators can edit the wrong directory, misdiagnose missing/stale agents, or trust the wrong ownership boundary for delegated work. Source: gaebal-gajae dogfood in `/home/bellman/Workspace/claw-code` on 2026-04-29 using rebuilt `./rust/target/debug/claw`; proof commands showed `agents help` omitting `.codex/agents` while `agents` loaded `analyst` from the existing `/home/bellman/.codex/agents/analyst.toml` with no `/home/bellman/.claw/agents` directory present.
-329. **Resume-safe slash `/agents --output-format json` downgrades structured agent inventory into prose even though top-level `claw agents --output-format json` returns machine-readable entries** — dogfooded 2026-04-29 on current `origin/main` / workspace HEAD `0f7578c0` after rebuilding the actual debug binary with `cargo run --manifest-path rust/Cargo.toml --bin claw -- version --output-format json`; `./rust/target/debug/claw version --output-format json` reported embedded `git_sha` `0f7578c0`, matching the workspace. Running `./rust/target/debug/claw --resume latest /agents --output-format json` returned only `{"kind":"agents","text":"Agents\n  20 active agents..."}`: the agent names, source ids, models, reasoning effort, active/shadowed state, and working-directory context are all flattened into one human prose string. In the same rebuilt binary and same workspace, `./rust/target/debug/claw agents --output-format json` returned a structured object with top-level `agents[]`, `count`, `summary`, `working_directory`, and per-agent fields such as `name`, `description`, `model`, `reasoning_effort`, `active`, `shadowed_by`, and `source`. The resume-safe slash surface therefore looks JSON-shaped while throwing away exactly the structured inventory that automation needs, and it diverges from the already-existing top-level command schema. This is distinct from #325's broad help JSON opacity and #328's source-root mismatch: the pinpoint is the `/agents` slash command losing structured inventory in resume mode even though the non-slash agents command already has it. **Required fix shape:** (a) make resume-safe `/agents --output-format json` reuse the same serializer/schema as `claw agents --output-format json` instead of wrapping rendered text; (b) preserve per-agent source/provenance fields, model/reasoning metadata, active/shadowed state, count/summary, and working-directory context; (c) keep `text` or `message` as an optional human summary only, not the sole payload; (d) add regression coverage proving top-level `claw agents --output-format json` and resume-safe `/agents --output-format json` expose equivalent structured agent inventory for the same workspace. **Why this matters:** `/agents` is the in-session delegation/staffing truth surface. Claws operating through `--resume latest` need to choose agents without scraping prose; losing structure at the slash boundary makes automated staffing brittle and contradicts the top-level command contract. Source: gaebal-gajae dogfood in `/home/bellman/Workspace/claw-code` on 2026-04-29 using rebuilt `./rust/target/debug/claw`; proof commands showed slash `/agents` JSON had only `kind,text` while top-level `agents` JSON had `agents[]` and provenance metadata.
-338. **Top-level `help --output-format json` and resume-safe `/help --output-format json` use different payload fields for the same help surface (`message` vs `text`)** — dogfooded 2026-04-29 on current `origin/main` / workspace HEAD `24ccb59b` after rebuilding the actual debug binary with `cargo run --manifest-path rust/Cargo.toml --bin claw -- version --output-format json`; `./rust/target/debug/claw version --output-format json` reported embedded `git_sha` `24ccb59b`, matching the workspace. Running `./rust/target/debug/claw help --output-format json` returned a valid JSON object with keys `kind,message`, while `./rust/target/debug/claw --resume latest /help --output-format json` returned the same conceptual help surface with keys `kind,text`. Both are prose-only help payloads, but automation now has to special-case whether help was reached through the top-level command dispatcher or the resume-safe slash dispatcher before it can even locate the rendered help body. This is distinct from #325's broader structured-schema absence: the pinpoint here is a concrete JSON field-name contract drift between two help entrypoints that should be equivalent or explicitly versioned. **Required fix shape:** (a) define one canonical help JSON body field such as `message` or `text` and use it consistently across top-level `help`, slash `/help`, and resume-safe `/help`; (b) if backward compatibility requires both fields temporarily, emit both with identical contents plus a `schema_version` and deprecation metadata; (c) add regression coverage proving `claw help --output-format json` and `claw --resume latest /help --output-format json` expose the same top-level field contract and `kind=help`; (d) document whether slash-command JSON is intended to share schemas with top-level command JSON or carry its own explicit schema namespace. **Why this matters:** help JSON is the bootstrap discoverability surface for claws. If the same help concept moves its body between `message` and `text` depending on invocation path, every orchestrator needs brittle per-entrypoint parsers before it can inspect commands, flags, or resume safety. Source: gaebal-gajae dogfood in `/home/bellman/Workspace/claw-code` on 2026-04-29 using rebuilt `./rust/target/debug/claw`; proof commands showed top-level help JSON keys `kind,message` and resume-safe slash help JSON keys `kind,text` on the same rebuilt binary.

-337. **`/session list --output-format json` session lifecycle objects expose `workspace_dirty: true` but provide no detail about which files are dirty or how many, making the flag unactionable for GC/cleanup decisions** — dogfooded 2026-04-29 by Jobdori on current main (`0f7578c`). Running `claw --output-format json --resume latest /session list` returns `session_details` where every `lifecycle` object for non-current sessions shows `"workspace_dirty": true, "pane_id": null` — and no `dirty_files`, `dirty_file_count`, `git_status`, or `uncommitted_changes` field. Additionally `"abandoned": true` appears on most saved sessions with no definition of the abandonment criterion. A session GC policy cannot determine whether dirty state is intentional (user edits) or stale (crash leftover), nor how many files are affected, nor what caused the abandonment. **Required fix shape:** (a) add `dirty_file_count: u32` to lifecycle objects when `workspace_dirty = true`; (b) optionally add `dirty_file_paths` (summarized); (c) add `abandoned_reason: "pane_closed" | "process_killed" | "session_replaced" | null`; (d) regression coverage.

+330. **`/stats` and `/cost` in `--resume` mode always return zero token counts regardless of saved session usage** — dogfooded 2026-04-29 by Jobdori on current main (`e7074f4`). Running `claw --output-format json --resume latest /stats` and `claw --output-format json --resume latest /cost` both return `{"input_tokens": 0, "output_tokens": 0, "total_tokens": 0, ...}` even when the session file was created by a real interactive claw run. The same zero-fill is produced by `claw --output-format json status` (usage sub-object). Inspection of the default session path (`~/.claw/sessions/.../session-*.jsonl`) shows the file has only 2 events (`session_meta`, `message`) with no usage/token records embedded. Two candidate root causes: (a) session serialization never writes usage events into the JSONL file even after real prompt exchanges, so resume-mode has no usage to replay; (b) resume-mode stat accumulation reads usage from memory-side counters that are always zero because no API calls happened in the resume-only invocation. Either way, the operator effect is the same: `--resume` + `/stats`/`/cost` cannot report what the session actually consumed. **Required fix shape:** (a) persist per-turn usage records (input/output/cache tokens per exchange) into the session JSONL at write time so resume-mode can reconstruct cumulative counts by replay; (b) expose a `"total_usage"` summary block at the tail of every session JSONL so resume-mode can read it in O(1) without full replay; (c) ensure `/stats` and `/cost` in resume-mode sum the persisted usage, not memory-side live counters; (d) add regression coverage proving `--resume SESSION.jsonl /stats` returns non-zero token counts after a session that made real API calls. **Why this matters:** token usage visibility is critical for quota management and cost attribution; if `--resume` mode always shows zeros, operators and orchestration lanes cannot trust usage data from saved sessions and must rely on external billing dashboards instead of in-band tooling.
