+# Harness CLI Workbench — Feature Plan
+
+Finalized 2026-07-29. Execution begins after PR #37 (knowledge layer M1–M4) merges. The live execution plan for the current phase is the single dated file under `docs/plans/` (Phase 1: `2026-07-29-harness-cli-phase1-core.md`); this document is the durable contract the phase plans derive from.
+
+## TL;DR
+
+The concrete target is five releases: **CLI modes → knowledge navigation → governed execution → durable runs/TUI → resource and plugin system**.
+
+The new command families are: `search`, `lookup`, `tree`, `checks`, `exec`, `bash`, `run`, `config`, `trust`, `resources`, `plugin`, and `tui`.
+
+## Boundary and invariants
+
+Harness owns deterministic capabilities; the host owns LLM reasoning. Constraints that bind every phase:
+
+- **CLI never calls an LLM.** An LLM host consumes Harness; Harness never consumes a model.
+- **Knowledge-layer invariants (settled on PR #37, do not re-litigate):** read paths never create the learnings store; the ops-JSON sole writer is `consolidate --apply`; the store lives at `~/.harness/knowledge/<repo-id>/` (local git, never pushed); promoted learnings are immutable targets in both lanes; human authority derives from on-disk verified evidence and must be at least as recent as any recorded governance decision.
+- **Search, lookup, and tree comply with the read-path rule** — navigation never creates or mutates the store.
+- **Resources and plugins never write the learnings store, the run journal, or evidence.** Plugins may contribute knowledge *sources*; ingestion still flows through the consolidation loop.
+- **Gate (vocabulary):** a gate is the existing plan/verification gate mechanism (`lib/gate.mjs`) that blocks lifecycle transitions until named checks and evidence pass. Later phases expose and record gates; they do not reinvent them.
+- **Enforcement classes:** every control in this plan is one of — **enforced** (blocks pre-execution), **detect-and-block** (best-effort detection that halts on trip), or **audit-only** (recorded, never blocks). Each control names its class where it is specified; "governed" always means at least detect-and-block.
+- **TUI boundary:** the TUI consumes the kernel in-process through the same command registry as the CLI — one behavior path, no separate implementation, no CLI shell-out requirement. This is the settled answer to the earlier SDK question; the CLI JSON/JSONL contracts serve out-of-process consumers on their program side (CI, hooks, Copilot, Codex) — the model side of any host consumes the agent lane per the output-lanes contract below.
+- **Three output lanes, produced at the source:** every command renders its one canonical result as ledger (human), envelope (programs/TUI), and agent (LLM) lanes — deterministically, never via a model pass, and never by converting one lane into another. See "Output lanes" below.
+
+## Output lanes: the three-audience contract
+
+Every workbench-dispatched command renders one canonical result three ways. All three
+renderings are deterministic CLI work — never a model pass. No output is ever converted
+from one audience's format into another's; each lane is produced at the source.
+
+| Lane | Audience | Format | Contract |
+|---|---|---|---|
+| Ledger | Human | Styled ledger rows (`lib/style.mjs` conventions: glyph/key/value, truecolor → 256 → ASCII degradation) | What the TUI panes and plain terminal output render |
+| Envelope | Programs / TUI | Versioned JSON envelope; JSONL streaming for long-running operations | Summary scalars first, detail arrays after, so one payload serves both a one-line footer and an expanded view. Long operations stream row-per-event with distinct `cancelled` vs `timed-out` terminal outcomes |
+| Agent | LLM | Budgeted plain text | Token/byte-capped at the source; injection-hardened; byte-metered |
+
+### Agent-lane requirements
+
+1. **Budgeted at the source.** Every agent rendering carries a hard local cap, following
+   the existing harness precedents: 2048-byte context pack, 220-token plan slice,
+   bounded `harness get` excerpts (40 lines / 2048 bytes), 1000-token repo map.
+   Truncation happens at item boundaries; the reported size never exceeds the budget.
+2. **Deterministic.** Produced by the CLI from the canonical result — never by asking a
+   model to summarize the envelope. This preserves the system-wide guarantee that
+   `orient`/`recall` and every read surface involve no model, network, or embedding call.
+3. **Hardened.** Wherever the content is retrieved text (knowledge, search hits, doc
+   excerpts), the rendering passes the existing data boundary: data-not-instructions
+   preamble framing, `inertLine` neutralization, and secret redaction.
+4. **Metered.** Rendered bytes are measured and emitted with the command's event so
+   `harness report` token/utilization SLOs account for the agent lane's real cost.
+
+### The consumption rule
+
+Agents consume the agent lane, never the envelope. JSON is token-inefficient and its
+arrays are unbounded, so envelope output must never enter model context. The envelope
+belongs to the TUI and tooling; the ledger belongs to humans. This is what makes the
+dual human/LLM promise real: zero tokens are ever spent translating tool output.
+
+### Boundary with the harness-evolution track
+
+The workbench defines the registry, envelope schema, and run-journal contracts; the
+harness evolution blueprint (`knowledge/proposals/harness-evolution-blueprint.md`, §9)
+commits its new surfaces (`knowledge status/promote/prune`, `index --structural`, the
+structural query) to being conforming citizens of them — registry-dispatchable,
+envelope-emitting, streaming-capable, and shipping an agent rendering per this contract.
+
+## Final command surface
+
+### Knowledge and workspace navigation
+
+```text
+harness index [--status]
+harness search <query>
+harness lookup <kind> <identifier>
+harness tree <workspace|knowledge|run|resources>
+harness get --docid <id> | --path <path>
+harness orient --query <task>
+```
+
+#### `search`
+
+```text
+harness search "lease fencing" \
+  --scope code,knowledge,plans \
+  --match ranked \
+  --explain
+```
+
+Features:
+
+- Scopes:
+  - `code`
+  - `knowledge`
+  - `learnings`
+  - `plans`
+  - `skills`
+  - `checks`
+  - `events`
+  - `runs`
+  - `all`
+- Match modes:
+  - `ranked`: BM25/knowledge ranking
+  - `literal`: exact content search
+  - `regex`: regex content search
+  - `path`: file/path discovery
+  - `symbol`: indexed symbol search
+- Filters:
+  - path/glob
+  - collection
+  - result type
+  - minimum score
+  - limit
+- Pagination cursor
+- Snapshot-specific search
+- Retrieval explanation
+- Explicit partial-result handling
+- Source, freshness, score and provenance in every result
+- Empty search returns success with zero results
+
+This command incorporates ranked search, grep-like content search, find-like path search, and symbol lookup without creating separate public commands for each tool.
+
+Federation semantics (`--scope` with multiple sources or `all`) are deterministic: per-source scores are normalized before merging; result identity for dedup is (source, entity id); ordering ties break stably by (score, source, id); cursors remain valid across sources; a failed source is reported explicitly in the result envelope, never silently dropped.
+
+#### `lookup`
+
+```text
+harness lookup <kind> <identifier>
+```
+
+Supported kinds:
+
+```text
+file | symbol | document | plan | skill | check | run | event | resource | learning | episode
+```
+
+Features:
+
+- Exact entity retrieval
+- Metadata and source provenance
+- Bounded content preview
+- Related entities
+- Current index generation
+- Structured not-found error
+
+`get` remains the document/file compatibility command; `lookup` handles the broader entity model. `lookup learning` and `lookup episode` are read-only views over the knowledge store and respect the read-path invariant.
+
+#### `tree`
+
+```text
+harness tree workspace [path] --depth 3
+harness tree knowledge [collection]
+harness tree run <run-id>
+harness tree resources
+```
+
+Features:
+
+- Workspace hierarchy respecting ignore rules
+- Knowledge collections, documents, and the learnings store (episodes → learnings → primitives, with provenance and governance state)
+- Run lifecycle and evidence hierarchy
+- Resource origin and override hierarchy
+- Depth, type and path filters
+- Human, JSON and TUI rendering
+
+`tree` is the single navigation verb: `harness tree resources` is canonical, and the resources family does not carry a duplicate `resources tree` subcommand.
+
+### Checks and execution
+
+```text
+harness checks list
+harness checks show <name>
+harness checks run <name>
+
+harness exec [options] -- <program> <args...>
+harness bash [options] -- <script>
+harness verify --plan <path>
+```
+
+#### `checks`
+
+Features:
+
+- List configured named checks
+- Inspect command, timeout, network and evidence policy
+- Run one named check directly
+- Stream output
+- Cancel execution
+- Show previous result and duration
+- Record diagnostic results
+
+Only `verify` binds check results to a plan and produces completion evidence.
+
+#### `exec`
+
+```text
+harness exec \
+  --cwd packages/harness \
+  --timeout 120s \
+  --network deny \
+  -- npm test
+```
+
+Features:
+
+- Safe argv execution without shell interpretation
+- Working-directory containment (enforced)
+- Configurable timeout (enforced)
+- Environment allowlist (enforced)
+- Network policy (enforced via the isolation backend; degrades to detect-and-block where the platform lacks isolation primitives, and the degradation is recorded in the audit event)
+- Streaming stdout/stderr
+- Ctrl-C cancellation
+- Descendant-process termination
+- Redacted terminal output (enforced)
+- Full-output artifact when output is truncated
+- Execution identity and audit event (audit-only)
+- Side-effect classification
+
+#### `bash`
+
+```text
+harness bash \
+  --cwd packages/harness \
+  --timeout 60s \
+  --network deny \
+  -- "git status --short"
+```
+
+Features:
+
+- Explicit shell interpretation
+- Same containment, redaction, timeout, cancellation and audit controls as `exec`
+- Clearly identified as shell execution in events and evidence
+- Policy can separately allow or deny Bash (enforced)
+
+The isolation backend defines per-platform behavior explicitly — which shell `bash` resolves to on Windows hosts and how descendant-process termination is implemented there — since the primary consumption platforms are Windows-based.
+
+### Runs and evidence
+
+```text
+harness run list
+harness run show <run-id>
+harness run resume <run-id>
+harness run tree <run-id>
+
+harness events [filters]
+harness report [filters]
+```
+
+Features:
+
+- Stable run IDs
+- Append-only run journal
+- Command start/progress/result entries
+- Plan and gate entries
+- Execution and mutation entries
+- Verification and evidence entries
+- Cancellation and timeout entries
+- Run status:
+  - running
+  - succeeded
+  - failed
+  - inconclusive
+  - blocked
+  - cancelled
+  - timed out
+- Resume from an explicitly safe boundary
+- No automatic replay of interrupted commands
+- Evidence freshness against repository and plan digests
+- Query runs by status, command, host, plan and date
+- Redacted output and configurable retention
+
+### Configuration and trust
+
+```text
+harness config show [--effective]
+harness config get <key>
+harness config set <key> <value> --scope user|project
+harness config validate
+
+harness trust status
+harness trust approve
+harness trust revoke
+```
+
+Features:
+
+- User and project configuration
+- Effective-value display with source provenance
+- Schema validation
+- Atomic configuration updates
+- Project identity and trust status
+- Explicit trust approval and revocation
+- Project resources and execution policies load only after trust (enforced)
+- Trust changes recorded in events
+
+### Resource management
+
+```text
+harness resources list
+harness resources show <resource-id>
+harness resources add <bundle>
+harness resources update <bundle>
+harness resources enable <resource-id>
+harness resources disable <resource-id>
+harness resources remove <bundle>
+harness resources reload
+```
+
+Supported resource types:
+
+```text
+skill | prompt | instruction | check | policy | preset | theme
+```
+
+Features:
+
+- Bundle manifests
+- Local, project and configured sources
+- Resource provenance
+- Deterministic precedence
+- Version and integrity pinning
+- Capability declarations
+- Explicit trust
+- Enable/disable controls
+- Recoverable updates
+- Reload without reinstalling Harness
+- Resource visibility from CLI and TUI (`harness tree resources`)
+
+Resource management **extends the existing hydration machinery** (`harness install`/`harness upgrade`, `retired.json` retirement) rather than introducing a parallel mechanism: bundles are the packaging and trust layer on top of the same discovery, precedence, and retirement pipeline.
+
+### Plugin management
+
+```text
+harness plugin list
+harness plugin show <plugin>
+harness plugin add <source>
+harness plugin enable <plugin>
+harness plugin disable <plugin>
+harness plugin update <plugin>
+harness plugin remove <plugin>
+```
+
+Plugin contributions:
+
+- Commands
+- Search scopes
+- Knowledge sources
+- Named checks
+- Policies
+- Event handlers
+- Output renderers
+- TUI panels
+- Provider and host adapters
+
+Plugin controls:
+
+- Out-of-process JSON/JSONL protocol
+- Protocol version negotiation
+- Manifest-declared capabilities
+- Explicit capability approval
+- Network and environment policy
+- Timeout and cancellation
+- Crash isolation
+- Redacted communication
+- No direct policy, journal, evidence, or learnings-store mutation (contributed knowledge sources flow through the consolidation loop)
+

+- ASCII fallback for limited terminals
+
+## Implementation sequence
+
+Prerequisite: PR #37 merges first. Phase 1 begins from the post-merge `main` so the registry migration covers the M1–M4 knowledge commands (`remember`, `learnings`, `learning …`, `consolidate`, `knowledge`, `eval-knowledge`) in one pass instead of racing them.
+
+## Phase 1 — CLI core and modes
+
+Implement:
+
+- Central command registry
+- Strict argument parser
+- Human output mode
+- Versioned JSON result mode
+- Versioned JSONL streaming mode
+- Agent-lane renderer: budgeted, hardened, metered plain-text rendering per command (see "Output lanes")
+- Unified error and status model, including distinct `cancelled` and `timed out` terminal outcomes with stable exit codes
+- Central event registry
+- Secret redaction
+- Async process runner
+- Timeout and cancellation
+- Actor and execution metadata
+- Migrate all existing commands to the new command registry — including the M1–M4 knowledge commands; `.github/skills/references/harness-tool-contract.md` and the existing JSON shapes are the compatibility fixtures
+
+Done when every current command supports consistent ledger, envelope, and agent output, and `verify` can stream and cancel.
+
+## Phase 2 — Knowledge operator
+
+Implement:
+
+- `search`
+- `lookup` (including `learning` and `episode` kinds)
+- `tree workspace`
+- `tree knowledge` (collections, documents, learnings store)
+- Enhanced `get`
+- Enhanced `orient`
+- Content-addressed indexes
+- Search snapshots
+- Ranked/literal/regex/path/symbol modes
+- Multi-source federation with the deterministic merge semantics above
+- Pagination and filters
+- Retrieval explanations
+- `recall` compatibility migration
+- Surface deferred M4 polish where it naturally lands (e.g., quarantined-learnings visibility in search/tree results)
+
+Done when code, knowledge, learnings and plans can be searched, exactly retrieved and structurally navigated through the CLI.
+
+## Phase 3 — Governed execution and control
+
+Implement:
+
+- `checks list/show/run`
+- `exec`
+- `bash`
+- Streaming `verify`
+- Configuration commands
+- Project trust commands
+- Environment allowlisting
+- Network policy
+- Isolation backend (with explicit per-platform behavior, Windows included)
+- Redacted output artifacts
+- Host hook enforcement
+- CI completion enforcement
+- Per-command-family authorization: which actors (user, CI, hook, LLM host, plugin) may invoke each family, recorded in policy
+- Cross-host validation through Copilot CLI and Codex CLI
+
+Done when hosts and users can execute commands through Harness with consistent policy, cancellation, evidence and audit behavior.
+
+## Phase 4 — Durable runs and TUI
+
+Two release boundaries inside one phase:
+
+**4a — Durable runs (ships first):**
+
+1. Append-only run journal
+2. `run list/show/resume/tree`
+3. Evidence and event queries
+4. Safe interruption recovery
+
+**4b — TUI:**
+
+5. TUI shell and command palette
+6. Search, plans and checks views
+7. Streaming execution and cancellation
+8. Runs, events and evidence views
+9. Resource inspection view
+
+Done when the TUI can perform the same search, lifecycle and execution operations as the CLI without implementing a separate behavior path.
+
+## Phase 5 — Resources and plugins
+
+Implement:
+
+- Resource manifests and bundles, extending the existing hydration/retirement machinery
+- Resource list/show/add/update/enable/disable/remove/reload and `tree resources`
+- Trust and integrity validation
+- Out-of-process plugin protocol
+- Plugin lifecycle commands
+- Extension commands, search sources, checks and policies
+- Extension TUI panels
+- Provider and host adapters through the plugin protocol
+
+Done when an external plugin can add one command, one search scope, one named check, and one TUI panel without modifying Harness core.

+
+# Phase 1 — CLI core: command registry, output modes, async runner
+
+## Overview
+
+First phase of the Harness CLI Workbench plan (`docs/architecture/harness-cli-workbench.md`): turn the CLI's dispatch, output, error, and process layers into the kernel every later phase (knowledge operator, governed execution, TUI) builds on. Behavior-compatible for all current consumers.
+
+## Context
+
+- **Prerequisite:** PR #37 (knowledge layer M1–M4, branch `feat/knowledge-layer`) merges first. This plan starts from post-merge `main` so the registry migration covers the knowledge commands in one pass. Do not start while #37 is open.
+- Current state: `packages/harness/bin/harness.mjs` dispatches via a hard-coded switch; process execution is blocking (`execSync`/`spawnSync`); JSON output shapes are ad-hoc per command.
+- Compatibility fixtures: `.github/skills/references/harness-tool-contract.md` (SSOT for orient/recall/get result shapes) plus the existing test suite (post-#38 main) and the `prompt-contracts` named check.
+- Knowledge-layer invariants bind this phase too: read paths never create the store; CLI never calls an LLM; redaction runs before persistence/emission.
+- Work happens in a worktree on a fresh branch per repo convention.
+
+## Intent Contract
+
+- **Goal:** every harness command dispatches through one registry with consistent human/JSON/JSONL output, a unified error/status model (distinct `cancelled` and `timed out` outcomes), secret redaction, and an async cancellable runner — with zero consumer breakage.
+- **Expected outputs:** see frontmatter `expected_outputs`.
+- **Success criteria:** AC1–AC9.
+- **Verification checks:** `harness-tests`, `prompt-contracts`, `build-assets` (`.github/harness/checks.yaml`).
+- **Organizational objective:** foundation for the five-release Harness CLI Workbench sequence; prerequisite for making the harness public.
+
+## Memory Cards
+
+- Knowledge-layer settled decisions and invariants — source: `docs/brainstorms/2026-07-26-knowledge-layer-design.md`
+- Harness design-system total coverage (all output through `lib/style.mjs`) — source: `docs/architecture/harness-cli-workbench.md` (TUI section) and `packages/harness/lib/style.mjs`
+- Tool contract SSOT — source: `.github/skills/references/harness-tool-contract.md`
+
+## Acceptance Criteria
+
+- [ ] **AC1** Every existing command — including `remember`, `learnings`, `learning …`, `consolidate`, `knowledge`, `eval-knowledge` — dispatches through the central registry; no hard-coded command switch remains in `bin/harness.mjs`.
+- [ ] **AC2** Strict argument parsing: unknown flags are rejected with a structured error; help output is consistent and registry-generated.
+- [ ] **AC3** Every command emits human output and a versioned JSON envelope (schema-version field); JSONL streaming exists where streaming is useful (at minimum `verify`); existing JSON shapes are preserved or explicitly versioned per the tool contract, with `prompt-contracts` green.
+- [ ] **AC4** Unified error/status model with stable exit codes, including distinct `cancelled` and `timed out` terminal outcomes.
+- [ ] **AC5** Blocking process execution is replaced by an async runner with timeout, Ctrl-C cancellation, and descendant-process termination.
+- [ ] **AC6** A secret-redaction pass runs on command output before emission and before any persistence (events, artifacts).
+- [ ] **AC7** Lifecycle events flow through a central event registry carrying actor and execution metadata.
+- [ ] **AC8** `harness verify` streams check output and can be cancelled mid-run, recording the `cancelled` outcome.
+- [ ] **AC9** Full regression: all existing tests pass and `build-assets` succeeds; no hydrated-skill caller of `orient`/`recall`/`get` observes a shape change without a version bump.
+- [ ] **AC10** Every registry command ships an agent-lane rendering per the output-lanes contract (`docs/architecture/harness-cli-workbench.md`): hard local budget with item-boundary truncation, deterministic (no model pass), `inertLine` + redaction hardening on retrieved text, and rendered bytes emitted with the command's event; envelope output never enters model context.
+
+## Technical Notes
+
+- Registry entries declare: name, args schema, side-effect class, required capabilities, output modes. This metadata is what Phase 3 policy and Phase 4 journal consume — design it as data, not convention.
+- Envelope versioning: single `schema` field on the JSON envelope; JSONL events carry `event` + `schema`. Deprecation policy lives in the tool contract.
+- Redaction: registered-secret masking (env-derived + configurable patterns); applies to terminal, JSON, JSONL, and events.
+- Keep `lib/style.mjs` as the sole renderer for human output (design-system total-coverage rule).
+
+## Plan
+
+- [ ] **P1.1** Registry + args schema + help generation; migrate 3 pilot commands (one simple, one JSON-heavy e.g. `orient`, one knowledge command e.g. `learnings`).
+- [ ] **P1.2** Output layer: versioned JSON envelope (summary scalars first, detail arrays after), JSONL writer, error/status model with exit-code table (incl. cancelled/timed-out), and the agent-lane renderer with per-command budgets, `inertLine` hardening, and byte metering.
+- [ ] **P1.3** Async runner (spawn-based) with timeout, cancellation, descendant termination; wire into `verify` streaming.
+- [ ] **P1.4** Secret redaction module; apply at emission and persistence boundaries.
+- [ ] **P1.5** Event registry with actor/execution metadata; migrate existing event writes.
+- [ ] **P1.6** Migrate all remaining commands; delete the switch; regenerate help; update tool contract with envelope versioning note.
+- [ ] **P1.7** Regression + contract pass (AC9), fixture updates where shapes were versioned.
+
+## Research Notes
+
+- Existing arg/flag helpers: `lib/argv.mjs`, `lib/flags.mjs`; command wiring in `lib/commands.mjs` — evaluate promote-vs-replace during P1.1.
+- `lib/events.mjs` is the current event write path; the 200-event cap/retention question belongs to Phase 4a, not this phase.

+/**
+ * Async process runner — spawn-based replacement for the blocking
+ * `execSync`/`spawnSync` call sites in this package (see verify.mjs,
+ * plan-scope.mjs, knowledge/store.mjs, etc.). Those stay on spawnSync for
+ * now; this module is additive and wired in by a later task.
+ *
+ * Contract: `runProcess` never rejects for process outcomes — it always
+ * resolves with `{ status, exitCode, signalName, durationMs, stdout,
+ * stderr, truncated }`. `status` is one of:
+ *   - 'ok'        exited zero, not cancelled or timed out
+ *   - 'failed'    exited non-zero, or died some other way we didn't ask for
+ *   - 'cancelled' the caller's AbortSignal fired
+ *   - 'timed-out' `timeoutMs` elapsed first
+ * 'cancelled' and 'timed-out' are reported regardless of the exit code the
+ * killed tree happens to produce — they must never collapse into 'failed'.
+ *
+ * Descendant termination: spawned detached (own process group) on POSIX so
+ * a negative pid signals the whole group (SIGTERM, escalating to SIGKILL
+ * after a grace period). On win32, process groups don't work the same way,
+ * so termination shells out to `taskkill /T /F` for the pid's whole tree.
+ *
+ * Injectable deps (spawnFn, now, platform, killFn) follow createStyle's
+ * pattern in style.mjs: real implementations by default, override any of
+ * them for deterministic tests.

+/**
+ * Deterministic secret redaction.
+ *
+ * A pure, offline masking pass over text and JSON-shaped values — no
+ * network, no model, no filesystem. This module only produces masked
+ * strings/structures; it does not decide WHERE those get applied. Wiring it
+ * into the actual emission/persistence boundaries (stdout, event log,
+ * telemetry, `harness report`, etc.) is later work (P1.5/P1.6) — this task
+ * only builds the redactor itself.
+ *
+ * Two independent masking layers, both applied by `redactText`:
+ *
+ *   1. Env-derived: the VALUE of any environment variable whose NAME looks
+ *      secret-shaped (`TOKEN`/`SECRET`/`KEY`/`PASSWORD`/`CREDENTIAL`/`AUTH`)
+ *      is masked wherever it appears verbatim OR percent-encoded
+ *      (`encodeURIComponent`) in text, keyed by that variable's name
+ *      (`«redacted:env:GITHUB_TOKEN»`). This catches secrets the process
+ *      actually holds, even when their shape doesn't match any known token
+ *      pattern (an internal API key, a raw password) — including when that
+ *      secret is embedded in a URL (a git remote, a webhook, a query
+ *      string) and therefore percent-encoded.
+ *   2. Pattern-derived: common credential SHAPES (GitHub tokens, AWS access
+ *      keys, JWTs, PEM key blocks, bearer headers, key=value secrets, …) are
+ *      masked wherever they appear, independent of the environment
+ *      (`«redacted:jwt»`). This catches secrets pasted into text that the
+ *      process never held as an env var (a leaked token in a log line).
+ *
+ * The mask format `«redacted:<kind>»` is fixed-width per kind, not a
+ * function of the matched secret's length — a masked value can't be used to
+ * infer how long the real secret was.
+ *
+ * This module composes with the existing `inertLine` data-boundary idiom
+ * (see `lib/commands.mjs` / `lib/context-pack.mjs`) rather than replacing
+ * it: `inertLine` neutralizes control characters so untrusted text can't
+ * forge structure at a render boundary; `redactText`/`redactValue` mask
+ * secret-shaped content so it never reaches that boundary in the first
+ * place. Deliberately independent of both those files (and of
+ * `lib/secret-scan.mjs`, the earlier best-effort screen used by knowledge
+ * capture) — no imports from any of them, so this module can be wired in
+ * wherever it's needed without pulling in unrelated subsystems.
+ *
+ * Regex-grade by design, same caveat as every credential screen in this
+ * codebase: best-effort shape matching, not a cryptographic guarantee.
+ *
+ * Known limitations (encoding transforms): env-derived masking defeats the
+ * raw value and its single-pass `encodeURIComponent` form only. It does NOT
+ * detect a secret hidden behind any OTHER transform — base64/base64url- or
+ * hex-encoding the whole value, double URL-encoding, case-folding, or a
+ * secret split across chunks/lines (streamed output that breaks a token
+ * mid-string across two `write()` calls, for instance) all pass through
+ * unmasked. Pattern-derived masking has the same "single literal shape"
+ * ceiling. None of this is a regression from a naive implementation — a
+ * fully transform-proof screen would need semantic/entropy analysis, out of
+ * scope for a deterministic, regex-grade module — but it is a real gap
+ * worth knowing before treating this module's output as a hard guarantee.
+ */
+
+// Env var NAME shape that reads as secret-carrying. Deliberately broad (no
+// word boundaries) per the accepted false-positive/false-negative trade —

+// only carve-outs.

+// SSH_AUTH_SOCK, CREDENTIAL_FILE, TOKEN_DIR are all "where the secret lives",
+// not the secret. Suffix-anchored so this only excludes vars that legitimately
+// END in one of these words — GITHUB_TOKEN_PATH_OVERRIDE (mid-string) still
+// gets screened.
+const ENV_BENIGN_SUFFIX_RE = /_(PATH|FILE|DIR|SOCK)$/i;

+/**
+ * Common credential SHAPES, independent of environment. Each entry's `re`
+ * does not need a `g` flag — normalizePattern adds one. `mask` is optional;
+ * when present it receives the same (match, ...capturedGroups) arguments

+ * the full replacement string (used by kv-secret/bearer-token to keep a
+ * readable prefix instead of swallowing it). When absent, the ENTIRE match
+ * is replaced by the fixed `«redacted:<kind>»` marker.
+ *
+ * Ordered most-specific-shape first, most-generic (kv-secret) last, so a
+ * narrowly-shaped secret (a JWT, a GitHub token) is classified by its own
+ * kind before the generic key=value sweep would otherwise claim it.
+ *
+ * Upper bounds on every quantifier are a deliberate perf/safety margin
+ * (req #4 2 MiB / req #3 never-throw-on-hostile-input): they cap the work a

+//   on exit. A true cycle (a node that is its own ancestor) is caught
+//   because the ancestor is still in `seen` while its own descendants are
+//   being walked.
+// - `memo` (a WeakMap) is the SHARING guard — every node whose redaction has
+//   already been FULLY computed, keyed to its finished result. Consulted
+//   before `seen`/depth, so once a node's subtree is done, every OTHER path
+//   that reaches the same node reuses the cached result in O(1) instead of
+//   re-walking it. Safe because `redactText`/`walk` are pure and
+//   deterministic — the same input node always produces the same output.
+//
+// Both are required together, not either alone:
+//   - `seen` alone (round 1 of this fix) correctly redacts a shared,
+//     non-cyclic node on every occurrence, but re-WALKS it from scratch each
+//     time — fine for a handful of duplicate references, but a diamond-
+//     shaped DAG (a node reachable via 2^k distinct paths at depth k, e.g.
+//     `{left: shared, right: shared}` nested k times) turns that repeated
+//     work exponential: measured ~34ms at depth 15 → ~7.8s at depth 23 on
+//     this module's own dev machine, effectively a hang, and well below
+//     MAX_WALK_DEPTH — an input-shaped denial-of-service that violates the
+//     "never throw/hang on hostile input" guarantee just as much as an
+//     uncaught exception would. Fixed per review round 2.
+//   - `memo` alone, without `seen`, would treat "currently being computed"
+//     (not yet in the memo) the same as "never seen" and recurse forever on

+ * Event registry — the central event emitter for the harness dispatch
+ * pipeline (Phase 1 task P1.5, see
+ * .superpowers/sdd/2026-07-29-harness-cli-phase1-core/task-5-brief.md).
+ * `lib/registry.mjs`'s `dispatch`/`dispatchLane` (the NEW envelope/agent
+ * output lanes from P1.2) call `emit`/`withCommand(...).emit` here instead
+ * of reaching into `lib/events.mjs` directly, so every event this module
+ * produces carries the SAME actor/execution metadata and is redacted BEFORE
+ * it ever reaches the injected `writeEvent` sink (AC6/AC7).
+ *
+ * `createEventRegistry({ writeEvent, redactor, actor, clock, pid,
+ * harnessVersion }) -> { emit(type, payload), withCommand(command) }`
+ *
+ *   - `writeEvent(payload)` — REQUIRED, single-argument sink. The caller
+ *     (bin/harness.mjs — "registry construction plumbing") binds this to
+ *     the real `lib/events.mjs` `writeEvent(workspace, flags, payload)` for
+ *     one resolved workspace/flags pair. Tests inject a spy instead. This is
+ *     deliberately NOT the 3-arg `lib/events.mjs` signature itself — it is
+ *     also the exact shape `lib/agent-lane.mjs`'s `recordAgentLaneBytes`
+ *     already expects from an `eventsApi` (`eventsApi.writeEvent(record)`),
+ *     so this registry composes with that existing, unmodified contract.
+ *   - `redactor` — defaults to the REAL `createRedactor()` (lib/redact.mjs),
+ *     secure by default; inject a marker/spy redactor to prove redaction
+ *     ran before persistence (AC6).
+ *   - `actor` — defaults to `detectActor()` (below), evaluated once per
+ *     `createEventRegistry(...)` call — the harness CLI calls this exactly
+ *     once per process (bin/harness.mjs), so actor detection happens once
+ *     per process as required (AC7 #2).
+ *   - `clock` — defaults to `() => new Date().toISOString()`; injectable
+ *     for deterministic tests. Note: when the injected `writeEvent` is the
+ *     REAL `lib/events.mjs` sink, that function stamps its own wall-clock
+ *     `ts` and ignores whatever `ts` arrives on `payload` (untouched,
+ *     off-limits legacy behavior — see the module doc there) — the
+ *     injected clock's determinism is therefore observable on the event
+ *     OBJECT this module constructs and passes to `writeEvent`, which is
+ *     what every test in test/event-registry.test.mjs asserts against.
+ *   - `pid`/`harnessVersion` — the `execution` block stamped on
+ *     `command.start` events ONLY, never on every event (AC7 #2).
+ *     `harnessVersion` defaults to this package's own package.json version.

+**Envelope versioning (Phase 1 workbench, additive).** Every registry-migrated command now also accepts `--output json-envelope\|agent\|jsonl` (`--output=value` works too): `json-envelope` wraps the same result data in a versioned `{schema, command, status, ...}` envelope, `agent` renders a budgeted plain-text summary for LLM callers, and `jsonl` (currently `verify` only) streams row-per-event with a terminal `result` row. `status` in all three uses one shared vocabulary — `ok\|failed\|cancelled\|timed-out`, plus `blocked` where gate-like semantics already use it. These are opt-in, additive lanes: every legacy shape documented below (the default ledger render and `--json`) is **unversioned and unchanged** — no `schema` field, no wrapper, byte-identical output. Do not rely on `--output` unless a command's help (`harness help <command>`) or this doc documents it for that command.

 ## Command catalog
 
 This table tracks only what differs in runtime character across commands — which turn a command runs on, whether it writes a lifecycle event, whether it mutates anything. Sigs and flags: `harness help <command>` (the CLI CATALOG is the single source of truth).

It does NOT mean these four commands are exempt from footnote ² below — the dispatch-level `command.start`/`command.result` bracketing still writes to `events.jsonl` for all four, just not under `init_repo`/`recall`/`validate_plan`/`index`.

+² **Every registered command dispatch (P1.6, `lib/registry.mjs`) is bracketed with `command.start`/`command.result` telemetry, independent of the domain-specific "Events" column above** — this is a dispatch-pipeline concern, not a per-command opt-in, so it applies uniformly regardless of whether that column says "writes" or "none". The one exception is `events` itself (footnote ³). A real, observable side effect: running ANY registered `harness` command — including ones whose Events column says "none", like `recall`, `get`, `learnings`, `report`, or `eval-knowledge` — creates/appends `.harness/events.jsonl` under whatever `--workspace` resolves to (default: the current directory), in ANY cwd, even one with no other `.harness/` state. Opt out with `--no-events`, `--dry-run`, or `HARNESS_NO_EVENTS=1` (all three short-circuit `lib/events.mjs#writeEvent` before anything is written, for both the domain-specific events above and this dispatch-level bracketing).
+
+³ `events` itself is the one command excluded from footnote ² (`entry.instrument === false`, `lib/registry.mjs`): its own handler's job is reading and summarizing everything already in `events.jsonl`, so bracketing its own dispatch would append that very invocation's own `command.start` to the file an instant before the handler reads it back — a self-referential read-your-own-write that would inflate `harness events`'s own totals on every call.
 
 **Query construction (deterministic-retrieval discipline):** build `--query` from the user's salient nouns and identifiers **verbatim** (e.g. `SYSTEM-OVERRIDE`, `payment`, `token`) — do not paraphrase intent into synonyms. The retrieval tokenizer normalizes identifier formats and morphology, but it cannot recover a term the query never contained. Passing the literal request terms is what keeps recall stable across phrasings.

 ## Acceptance Criteria
 
-- [ ] **AC1** Every existing command — including `remember`, `learnings`, `learning …`, `consolidate`, `knowledge`, `eval-knowledge` — dispatches through the central registry; no hard-coded command switch remains in `bin/harness.mjs`.
-- [ ] **AC2** Strict argument parsing: unknown flags are rejected with a structured error; help output is consistent and registry-generated.
-- [ ] **AC3** Every command emits human output and a versioned JSON envelope (schema-version field); JSONL streaming exists where streaming is useful (at minimum `verify`); existing JSON shapes are preserved or explicitly versioned per the tool contract, with `prompt-contracts` green.
-- [ ] **AC4** Unified error/status model with stable exit codes, including distinct `cancelled` and `timed out` terminal outcomes.
-- [ ] **AC5** Blocking process execution is replaced by an async runner with timeout, Ctrl-C cancellation, and descendant-process termination.
-- [ ] **AC6** A secret-redaction pass runs on command output before emission and before any persistence (events, artifacts).
-- [ ] **AC7** Lifecycle events flow through a central event registry carrying actor and execution metadata.
-- [ ] **AC8** `harness verify` streams check output and can be cancelled mid-run, recording the `cancelled` outcome.
-- [ ] **AC9** Full regression: all existing tests pass and `build-assets` succeeds; no hydrated-skill caller of `orient`/`recall`/`get` observes a shape change without a version bump.
-- [ ] **AC10** Every registry command ships an agent-lane rendering per the output-lanes contract (`docs/architecture/harness-cli-workbench.md`): hard local budget with item-boundary truncation, deterministic (no model pass), `inertLine` + redaction hardening on retrieved text, and rendered bytes emitted with the command's event; envelope output never enters model context.

Existing JSON shapes byte-preserved, `prompt-contracts` green. *(Scope amended at final review 2026-08-06 — original text said "every command"; delivered surface + explicit-error behavior recorded honestly.

+
+## Primitive Governance
+
+This plan modifies one existing primitive — the `harness-tool-contract.md` reference — so the create-primitive governance applies (skill read; recorded in `skills_used`):
+
+- Primitive classification: reference (dense supporting material under `.github/skills/references/`); this plan modifies the existing harness tool contract in place and creates no new primitive.
+- Overlap analysis: none introduced — the edit corrects the existing SSOT reference itself (registry replaces the retired CATALOG as help truth, Events columns made accurate, envelope note scoped to lane-bearing commands); no new artifact overlaps existing capability.
+- Artifact structure: unchanged — a single markdown reference at `.github/skills/references/harness-tool-contract.md`, keeping its table-plus-footnotes layout.
+- Trigger and negative-trigger implications: none — references load on demand from their owning skills; no trigger surface changes.
+- Verification expectations: the `prompt-contracts` named check pins the tool-contract truths, with `harness-tests` covering the behavior the doc describes; both green in this plan's evidence.
+- Registry and documentation impact: the edit is itself the documentation impact (envelope-versioning note, registry-as-truth wording, accurate event columns and opt-outs); no capability-registry entries change.

Subject: [PATCH 09/23] fix: make secret redaction universal across all
 emission and persistence boundaries

Close two rounds of external adversarial review: route every machine and
human output sink (legacy --json, JSONL, events log incl. metadata, ledger,
debug stack, telemetry sync) and the toJSON serialize path through one
redacting boundary; honor the -- literal argument boundary in every flag
read; settle runner cancellation only after the process group is reaped;
map verify timeout to exit 8; stream and redact check output live; fix
JSONL backpressure and quadratic UTF-8 clipping.

+## External Review (Codex) — hardening rounds
+
+Two Codex adversarial reviews after the internal final review found real gaps the in-house chain missed (root cause: redaction was wired per-new-output-lane; no component made it universal, and the legacy `--json`/JSONL serializers plus the event-metadata path leaked). All findings across both rounds are fixed and internally verified:
+
+- **Round 1 (3 Critical + 8):** legacy `--json`/JSONL/events-sink redaction, object-key redaction, `--` boundary in `parseFlags`, timeout→exit 8, runner PID-guard + grandchild escalation, `report` self-instrumentation, verify live-streaming, agent-lane fence/metering. Codex round-2 confirmed 8/11 fixed.
+- **Round 2 (3 partial + 7 new):** `--` missing-value/top-level edges, SIGKILL group-settlement race, agent-lane fence injection, multi-line PEM streaming leak, human/ledger + debug-stack leak (now in scope per user decision — AC6 is an absolute guarantee), `toJSON` redaction bypass (closed with a final serialize-then-`redactText` string pass), `report --sync` re-persistence, `__proto__` byte-identity, JSONL backpressure, quadratic UTF-8 clip. All 10 fixed with 22 net-new regression tests and per-finding evasion probes; suite 919/919.
+
+**Verification status (honest):** all headline bypasses re-verified by the controller (`toJSON`, `--`-boundary, `bogus -- --json`, ledger `--why` secret, `__proto__` survival, secret-free byte-identity) and by the implementer's own evasion probes. The **third** independent Codex certification could not run — the Codex CLI's OAuth token expired (401) mid-session. The last independent third-party confirmation is Codex round 2 (8/11); the round-2 residuals + new findings are controller-verified, not Codex-re-certified. Re-run `codex login` then a third Codex pass to close that gap if independent certification is required before merge.
+
 ## Technical Notes
 
 - Registry entries declare: name, args schema, side-effect class, required capabilities, output modes. This metadata is what Phase 3 policy and Phase 4 journal consume — design it as data, not convention.

Subject: [PATCH 10/23] fix: redact JSON at value level so masking can never
 corrupt escaping

The serialize-then-mask pass could consume a JSON escape backslash when a
secret-shaped value preceded an escaped quote, terminating the string early
and emitting unparseable JSON from every machine sink. Mask through a
stringify replacer instead: it still runs after toJSON, and the serializer
owns escaping.

Subject: [PATCH 11/23] fix: classify missing required arguments as usage
 errors

recall, get, and plan-new reported a harness fault (E_UNEXPECTED, exit 1)
when invoked without a required argument, so callers could not distinguish
misuse from breakage. Enforce the requirement declaratively in the registry
and raise the standard usage error instead; the guidance messages are
unchanged.

Subject: [PATCH 12/23] docs: plan the remaining workbench releases through
 phase 5

Records scope, acceptance criteria, verification, and risks for the
knowledge operator, governed execution, durable runs, TUI, and plugin
releases, carries every phase 1 deferral to the phase that inherits it,
and keeps the settled TUI design direction with the work it belongs to.

+# Harness CLI Workbench — Delivery Plan, Phases 2–5
+
+Companion to `harness-cli-workbench.md` (the contract: boundary, invariants, output lanes, command surface). That document says *what* the workbench is; this one says *how the remaining releases get built* — scope, acceptance criteria, verification, risks, and what each phase inherits from the one before.
+
+Phase 1 (CLI core) shipped the kernel: command registry, three output lanes, async cancellable runner, universal secret redaction, event registry. Everything below builds on those seams.
+
+**Plan-file convention.** This repository keeps at most one dated plan under `docs/plans/` at a time (enforced by the `prompt-contracts` check). Each phase gets its own dated plan file when its PR opens, derived from the corresponding section here, and that file is removed after merge. This document is the durable source those transient plans are cut from.
+
+## Sequence and dependencies
+
+```text
+Phase 1 ✅ CLI core ──▶ Phase 2 knowledge operator ──▶ Phase 3 governed execution
+                                                              │
+                                            Phase 4a durable runs ──▶ Phase 4b TUI
+                                                              │
+                                                    Phase 5 resources & plugins
+```
+
+Phase 3 depends on Phase 1's runner and side-effect metadata, not on Phase 2. Phase 4a depends on Phase 1's event registry. Phase 4b depends on 4a (run views need the journal) and reads better after Phase 3 (execution views need something to execute). Phase 5 depends on the existing hydration pipeline plus Phase 1's registry.
+
+## Debt carried out of Phase 1
+
+These are the deferred items whose natural home is a later phase. Each phase's plan must pick up the ones assigned to it.
+
+| Item | Origin | Assigned |
+|---|---|---|
+| Expand `resultOf` producers to all commands (reverses the AC3 lane-scope amendment) | P1.2 / final review | Phase 2 |
+| Surface quarantined learnings in search/tree results | P1.4 / M4 backlog | Phase 2 |
+| ~20 legacy `writeEvent` call sites bypass the event registry (no actor metadata) | P1.5 review, deferred with ruling | Phase 4a |
+| `events.jsonl` 200-event cap and retention contract | P1.5 brief (explicitly out of scope) | Phase 4a |
+| `legacyResultForStatus` maps cancelled/timed-out to `warn`, hiding them from `--failures` | P1.5 review | Phase 4a |
+| `learningsResultOf` duplication with `cmdLearnings` | P1.6 judgment call | Phase 2 |
+| Redaction residuals: glued-secret `\b` boundaries, base64/split-transform env values | P1.4 reviews | Phase 3 |
+| Cycle-guard returns masked sentinel — revisit if untrusted cyclic input ever reaches redaction | P1.4 round 2 | Phase 3 |
+
+## Phase 2 — Knowledge operator
+
+**Goal.** Code, knowledge, learnings, and plans become searchable, exactly retrievable, and structurally navigable through the CLI — on the substrate the merged knowledge layer (M1–M4) already provides.
+
+**Scope.** `search` (ranked, literal, regex, path, symbol match modes; scopes incl. `learnings`), `lookup` (all entity kinds incl. `learning`/`episode`), `tree workspace|knowledge`, enhanced `get`/`orient`, content-addressed indexes, search snapshots, deterministic multi-source federation, pagination and filters, retrieval explanations, `recall` compatibility migration with deprecated aliases.
+
+**Acceptance criteria (draft — refine when the plan file is cut).**
+1. `search` implements all five match modes with the documented scope list; empty result exits 0 with an empty result set.
+2. Every result carries source, scope, location/entity id, relevance score, index generation, and retrieval reason under `--explain`.
+3. Federation across scopes is deterministic: normalized scores, stable tie-break, cursor validity across sources, explicit partial-source failure reporting.
+4. `lookup` resolves every declared kind and returns a structured not-found error.
+5. `recall`/`get` continue to work via deprecated aliases; `harness-tool-contract.md` and every hydrated skill caller are updated in the same phase.
+6. Read paths never create the knowledge store (Phase 1 invariant holds under the new commands).
+7. All three output lanes work for every command this phase adds or touches, closing the AC3 lane-scope amendment.
+
+**Verification.** `harness-tests`, `prompt-contracts`, `build-assets`, plus new index/federation determinism tests (same query + same snapshot ⇒ byte-identical results).
+
+**Risks.** Index generation identity must be stable enough to make results replayable; federation scoring is the most likely source of nondeterminism; the `recall` migration touches hydrated skills, so contract drift is the recurring Phase 1 failure mode to watch.
+
+## Phase 3 — Governed execution and control
+
+**Goal.** Hosts and users execute commands through Harness with consistent policy, cancellation, evidence, and audit.
+
+**Scope.** `checks list/show/run`, `exec` (argv-only), `bash` (explicit, separately policy-gated), streaming `verify` (already delivered in Phase 1 — extend, don't rebuild), `config` (user/project scopes, effective values with provenance, schema validation, atomic writes), `trust` (project identity, approve/revoke, policy-and-resource loading gated on trust), environment allowlisting, network policy, isolation backend, redacted output artifacts, host-hook and CI completion enforcement, per-command-family authorization, cross-host validation on Copilot CLI and Codex CLI.
+
+**Acceptance criteria (draft).**
+1. Every control declares and honors its enforcement class: enforced, detect-and-block, or audit-only.
+2. `exec` never invokes a shell; `bash` is separately allowed or denied by policy; both are identified distinctly in events and evidence.
+3. Working-directory containment, timeout, environment allowlist, and network policy are enforced; where the platform lacks isolation primitives the degradation is recorded in the audit event.
+4. Per-platform behavior is explicit — which shell `bash` resolves to on Windows and how descendant termination works there.
+5. Command and mutation audit entries are written for every execution, redacted before persistence.
+6. Trust gates project resource and policy loading; trust changes are recorded.
+7. The same representative workflow runs through two named hosts using only documented CLI contracts.
+
+**Verification.** `harness-tests`, `prompt-contracts`, `build-assets`, plus isolation-backend tests per platform and a cross-host validation run.
+
+**Risks.** This is the phase where genuinely untrusted output flows through the redaction layer — the Phase 1 residuals in the debt table land here, and the redaction test surface should grow with adversarial fixtures. Windows behavior is the least-covered area in the current suite.
+
+## Phase 4a — Durable runs
+
+**Goal.** Run history becomes queryable and resumable; ships before any TUI work starts.
+
+**Scope.** Append-only run journal with stable ids, `run list/show/resume/tree`, evidence and event queries, safe-boundary resume with no automatic replay of interrupted commands, evidence freshness against repository and plan digests, retention and redaction policy for durable output.
+
+**Acceptance criteria (draft).**
+1. Every run carries a stable id; the journal is append-only and never rewritten.
+2. Journal entries cover command start/progress/result, plan and gate, execution and mutation, verification and evidence, cancellation and timeout.
+3. Run status uses the unified vocabulary incl. `cancelled` and `timed out` as distinct terminal states.
+4. `resume` restarts only from an explicitly safe boundary; interrupted commands are never auto-replayed.
+5. Runs are queryable by status, command, host, plan, and date.
+6. The ~20 legacy `writeEvent` call sites migrate onto the event registry, gaining actor metadata (Phase 1 deferral closed).
+7. Retention replaces the current 200-event cap with a stated policy; `--failures` surfaces cancelled and timed-out runs correctly (Phase 1 deferral closed).
+
+**Verification.** `harness-tests`, `prompt-contracts`, plus journal-integrity tests (crash mid-run leaves a readable journal; resume lands on a safe boundary).
+
+**Risks.** The current `.harness/` state is gitignored and explicitly ephemeral; making it durable changes that contract and needs a migration story for existing workspaces.
+
+## Phase 4b — TUI
+
+**Goal.** `harness tui` performs the same search, lifecycle, and execution operations as the CLI, through one kernel and one behavior path.
+
+**Design direction (settled).** Session Ledger — the flow-document form: a scrolling transcript in the terminal's main buffer (scrollback preserved; alt-screen a config, not a default), persistent chrome limited to a two-hairline editor and one dim status line, block meaning carried by faint background tints rather than boxes, near-monochrome with the harness v0.1 palette doing the semantic work, views dissolved into commands that print blocks, markdown plans rendered inline, ephemeral overlays for the command palette and run tree, editor border reflecting gate state, consequence context in the hint row, and an exit ritual that prints the closing tally and resume command into scrollback. Reference mock and research: the design session under `~/.gstack/projects/*/designs/harness-tui-*`.
+
+**Scope.** TUI shell and command palette; search, plans, checks views; streaming execution with cancellation; runs, events, evidence views; resource inspection view; ASCII fallback for limited terminals; all rendering through the existing design system.
+
+**Acceptance criteria (draft).**
+1. Every TUI operation dispatches through the same command registry as the CLI — no second behavior path, no shell-out.
+2. Scrollback, text selection, and terminal search keep working in the default mode.
+3. Streaming output renders without flicker; cancellation is available from every long-running view.
+4. All six state tokens render through `lib/style.mjs`, degrading to ASCII on limited terminals.
+5. The TUI performs search, plan inspection, check execution, and run navigation without a capability the CLI lacks.
+
+**Verification.** `harness-tests` plus TUI component tests; a rendering-golden approach for the ledger grammar.
+
+**Risks.** Terminal compatibility is the classic sink (every surveyed tool was forced to ship both buffer modes); budget for it rather than discovering it. Keep the kernel dependency one-directional — the TUI consumes the registry, never the reverse.
+
+## Phase 5 — Resources and plugins
+
+**Goal.** An external plugin can add one command, one search scope, one named check, and one TUI panel without modifying Harness core.
+
+**Scope.** Resource manifests and bundles extending the existing hydration/retirement machinery (`install`/`upgrade`/`retired.json`) rather than a parallel mechanism; `resources list/show/add/update/enable/disable/remove/reload` and `tree resources`; provenance, deterministic precedence, version and integrity pinning, capability declarations, explicit trust; out-of-process plugin protocol with version negotiation, manifest-declared capabilities, explicit capability approval, network and environment policy, timeout and cancellation, crash isolation, redacted communication.
+
+**Acceptance criteria (draft).**
+1. Bundles ride the existing hydration pipeline; no parallel install path exists.
+2. Resource precedence is deterministic and inspectable, with provenance shown per resource.
+3. Distributed bundles require integrity pinning and explicit trust before loading.
+4. Plugins run out-of-process over versioned JSON/JSONL, with capabilities approved explicitly.
+5. Plugins never mutate policy, the run journal, evidence, or the learnings store; contributed knowledge sources flow through the consolidation loop.
+6. A crashing plugin cannot take down the host process.
+
+**Verification.** `harness-tests`, `prompt-contracts`, `build-assets`, plus a fixture plugin exercising all four contribution types end to end.
+
+**Risks.** This is the largest trust-boundary expansion in the roadmap; the Grok Build telemetry incident is the cautionary case — local-first defaults and explicit approval are the posture, and the security review for this phase should be adversarial from the start.
+
+## How each phase gets executed
+
+1. Cut the dated plan file for the phase from its section here (`docs/plans/<date>-<slug>.md`, plan schema v1, named checks in `verification.required`, review roster in `reviews.required`).
+2. Work in a worktree on a branch off current `main`; open a draft PR early with the workstream checklist.
+3. Implement in reviewable workstreams, each landing as one commit after its own review pass.
+4. Close with the full suite, the named checks, `harness verify --plan` for the evidence artifact, and a whole-branch review — including a cross-model pass, which is what caught the systemic redaction gap in Phase 1.
+5. After merge, delete the dated plan file and promote anything durable into `docs/architecture/` or `knowledge/solutions/`.

Subject: [PATCH 13/23] ci: exercise the harness CLI on a real Windows runner

The primary consumption platform is Windows, but every check ran on Linux,
leaving the win32 branches untested: descendant termination via taskkill,
LOCALAPPDATA path resolution, console glyph degradation, and the .cmd shim.
Captures console output verbatim as an artifact.

Subject: [PATCH 14/23] docs: specify the command palette as a registry index,
 not a second grammar
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Settles the TUI command surface against ground truth read from eight
installed agent CLIs (pi, Claude Code, Codex, Cursor, Grok, Amp, Warp,
Gemini) — binaries, bundles, settings schemas and shell completions.

The CLI grammar does not change. An earlier proposal to collapse 91
command-specific flags into subcommands and a config store is rejected:
it paid a full migration cost to serve one of three audiences. Models
read a tool description per call; shell users have --help and completion;
only the TUI lacked a discovery affordance, and an index supplies it.

Contract additions:
- palette is a flat searchable index over commands, verbs and skills
- no "--" is ever typed in the TUI; noun+verb resolves to argv internally
  and the resolved command is echoed into the ledger
- ":" namespaces (skill:consolidate), whitespace separates
- sigils are /, @, !, !!; entry on / and Ctrl-P, never Ctrl-K
- side-effect class shown per row

Phase 2 picks up the registry metadata that feeds it: enumerate ~18
prose-only verbs, tag all 98 options verb/prompt/cli-only, add surfaces
and userInvocable. Standalone value ahead of any TUI — richer help, and
it closes a strict-validation gap where an option declared on a parent
validates against a verb that cannot accept it.

Phase 4b gains bidirectional assertions so the index cannot drift from
dispatch — the failure mode every surveyed tool has already shipped.

+## Settled decisions — command surface
+
+Recorded so they are not re-litigated. Each was decided against ground truth read from eight agent CLIs installed locally (pi 0.82.1, Claude Code 2.1.220, Codex 0.146.0, Cursor Agent 2025.09.18, Grok 0.2.67, Amp, Warp v0.2026.08.04, Gemini) — binaries, bundles, settings schemas, and shell completions, not documentation.
+
+**1. The CLI grammar does not change.** No flag is removed, renamed, or deprecated; no subcommand migration; no `config` store replacing configuration flags. An earlier proposal to collapse 91 command-specific flags was rejected: it paid a full migration cost — every hydrated skill calling `harness recall --collection …` breaks — to serve one of three audiences. The model reads a tool description per call and has no memory burden. A person in a shell has `--help` and completion. Only the TUI user lacked a discovery affordance, and an index supplies it without touching the grammar.
+
+**2. The palette is an index, not a grammar.** One flat namespace over commands, their verbs, and skills — currently 24 + 98 + 25 = 147 entries. Reaching a capability never requires knowing its parent.
+
+**3. No `--` is typed in the TUI.** Universal across all eight tools surveyed: not one accepts flag syntax inside a slash command. The palette presents noun + verb and resolves to argv internally, echoing the resolved command into the ledger.
+
+**4. `:` namespaces; whitespace separates.** No surveyed tool uses `:` as a command/subcommand separator. Three use it for namespace or scope (pi `/skill:name`, Grok `/local:commit`, Warp's palette filter prefixes). Claude Code stores `:` in the registered name and accepts a space on the input line — the pattern adopted here. This also resolves the live collision in this repository, where `/consolidate` and `/recall` exist both as harness commands and as prompt-library skills.
+
+**5. Sigils are `/`, `@`, `!`, `!!`.** The surveyed vocabulary converged on `/`, `@`, and a shell escape; `#` and `>` are dispatched by nobody. The `!`/`!!` split (output in context vs. private) is pi's, and is better than the single `!` that Claude Code, Codex, Cursor, and Grok ship.
+
+**6. `Ctrl-P`, not `Ctrl-K`.** Warp binds `Ctrl-K` to `kill_to_line_end` and Grok to scroll-up, both deliberately — it belongs to readline. `Cmd-K` aliases on macOS only.
+
+**7. The handler lives in the registry entry.** Pi keeps a data-only command table with dispatch in a separate branch chain, and the two have already drifted — three commands are dispatched but absent from the table, making them undiscoverable. A registry that does not own dispatch will drift the same way.
+
+**8. Side-effect glyphs in the palette are ours alone.** No surveyed tool can show what a command will do before it runs, because none declares a side-effect class per command. Harness already does, on every entry.
+
 ## Phase 2 — Knowledge operator
 
 **Goal.** Code, knowledge, learnings, and plans become searchable, exactly retrievable, and structurally navigable through the CLI — on the substrate the merged knowledge layer (M1–M4) already provides.
 
 **Scope.** `search` (ranked, literal, regex, path, symbol match modes; scopes incl. `learnings`), `lookup` (all entity kinds incl. `learning`/`episode`), `tree workspace|knowledge`, enhanced `get`/`orient`, content-addressed indexes, search snapshots, deterministic multi-source federation, pagination and filters, retrieval explanations, `recall` compatibility migration with deprecated aliases.
 
+**Plus: the command index (registry metadata).** The palette ships in 4b, but the metadata it reads belongs here — it is the same idea as the rest of this phase (make things findable) applied to commands, and it carries standalone value two phases before any TUI exists: richer `harness help`, and a strict-validation gap closed. Today `harness knowledge status --branch x` validates, because `--branch` is declared on the parent and nothing knows it is meaningless for that verb.
+
+Three registry additions, all internal and additive:
+
+- **Enumerate prose-only verbs.** `learning <retire|dispute|confirm|promote>`, `knowledge <on|suggest|off|freeze|capture-only>`, and `plan-new`'s risk tiers exist only inside `usage:` strings — roughly 18 working subcommands invisible to any index. Move them into data. Behavior is unchanged: `harness learning retire abc --reason "…"` runs identically before and after.
+- **Tag every option with a TUI disposition** — `verb` (its own palette row, ~19), `prompt` (a picker after the verb is chosen, ~34), or `cli-only` (never shown, ~45). Dependent options declare `requires:` so they attach to a parent verb instead of floating in as nonsense rows.
+- **Add `surfaces` and `userInvocable` per entry.** Warp's settings schema tags each of its 219 keys with the renderers that consume it; this is the command-side equivalent, and `userInvocable` is the field this repository's skills already carry.
+
 **Acceptance criteria (draft — refine when the plan file is cut).**
 1. `search` implements all five match modes with the documented scope list; empty result exits 0 with an empty result set.
 2. Every result carries source, scope, location/entity id, relevance score, index generation, and retrieval reason under `--explain`.

 5. `recall`/`get` continue to work via deprecated aliases; `harness-tool-contract.md` and every hydrated skill caller are updated in the same phase.

+8. Every verb reachable on the CLI is enumerable from the registry — no capability exists only inside a `usage:` string. A test asserts the count against a fixture so a new prose-only verb fails the build.

+**Risks.** Terminal compatibility is the classic sink (every surveyed tool was forced to ship both buffer modes); budget for it rather than discovering it. Keep the kernel dependency one-directional — the TUI consumes the registry, never the reverse. The bidirectional assertion in AC7 is the specific guard against the failure every surveyed tool has shipped: a palette list and a dispatcher that drift until commands become unreachable or undiscoverable.

+### Command palette
+
+The palette is a **searchable index over the command registry**, not a second command grammar. It is the TUI's only command-entry surface.
+
+**The CLI grammar does not change to accommodate it.** Every flag the CLI accepts today it still accepts; nothing is removed, renamed, or deprecated. The model invokes `harness <command> --flags` through the agent lane and never sees the palette; a person in a shell keeps `--help` and shell completion. The palette exists because the TUI is the one surface with neither.
+
+**No `--` is ever typed in the TUI.** The index contains options so a capability can be *found*; it must never require one to be *written*. The palette presents **noun + verb**, and the registry maps the verb onto the argv the CLI already accepts:
+
+```text
+index structural      →  harness index --structural
+index status          →  harness index --status
+learnings why         →  harness learnings --why <id>
+knowledge promote     →  harness knowledge promote --branch <key>
+```
+
+The left column is the TUI's entire vocabulary. The resolved argv is echoed into the ledger after the run, so the surface stays auditable and the shell form is learned by observation rather than by being typed.
+
+Contract:
+
+- **One flat namespace.** Commands, their verbs, and skills are sibling entries — reaching a capability never requires knowing its parent. `structural` resolves without the user knowing it lives under `index`.
+- **Skills are namespaced with `:`.** `/consolidate` is the deterministic command; `/skill:consolidate` is the workflow that calls it. The command owns the bare name; the qualified form is the escape hatch.
+- **Ranking is word-boundary weighted**, not substring. Exact match preselects; declared aliases outrank prefix matches.
+- **Values come from pickers.** A verb needing a value opens a chooser populated from live state (branch keys, learning ids, plan paths) — never a typed flag.
+- **Dependent options are refinements, not entries.** An option valid only alongside another (`--since` requires `--structural`) attaches to its parent verb and is offered after selection, never listed independently.
+- **Every row carries its side-effect class** — `read`, `mutate`, `execute` — so the consequence of a command is visible before it runs. This is possible because the registry already declares it per command.
+- **Availability is explained, not hidden.** A command that cannot currently run stays listed and greyed, carrying its reason (`no plan under docs/plans/`).
+- **Entry points:** `/` at line start, plus a configurable chord defaulting to `Ctrl-P` (`Cmd-K` aliased on macOS). `Ctrl-K` is reserved for readline's kill-to-line-end.
+- **Composer sigils:** `!` runs a shell command and puts its output in context, `!!` runs it privately, `@` completes file paths. No other sigil dispatches.

Subject: [PATCH 15/23] feat(harness): registry schema for verbs, TUI
 dispositions, and surfaces

Adds the metadata the command palette reads, with no behavior change for
any existing entry:

- SURFACES / TUI_DISPOSITIONS constants and registration-time validation
- entry.verbs[] so subcommands stop living only inside usage: prose
- per-flag tui disposition, requires[], and verbs[] scoping
- entry.surfaces and entry.userInvocable, defaulted to visible

Defaults are asymmetric on purpose. A command defaults to all three
surfaces, so forgetting to annotate leaves it discoverable rather than
silently dropping it from the palette. An option defaults to cli-only,
because a wrongly-hidden option is still reachable from the CLI while a
wrongly-shown one puts flag syntax in front of a TUI user.

validateArgs now enforces flag dependencies and verb scoping once every
flag is known to be declared, closing the gap where an option declared on
a parent validated against a verb that cannot accept it.

Subject: [PATCH 16/23] feat(harness): annotate every command with verbs,
 dispositions, and surfaces
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Enumerates 15 subcommands that previously existed only as prose inside
usage: strings — knowledge (11) and learning (4) — so the palette can see
them. plan-new declares none: its green|amber|red alternation is the
--risk flag's value enum, not a verb set, and 'plan-new green' was never
legal.

All 98 flag slots carry an explicit disposition: 12 verb, 55 prompt,
31 cli-only. learnings --why is a verb despite taking a value, because it
selects what the command does rather than parameterizing what it would do
anyway.

Adds flag dependencies (index --since needs --structural; consolidate
--apply needs --ops) and verb scoping (knowledge --branch to promote and
prune, --merged/--stale/--yes to prune, learning --to to promote).
--reason stays unscoped: all four learning actions record it.

install, upgrade, uninstall, init-repo, and resolve are cli-only surfaces;
resolve is additionally not user-invocable, since its output is a path
meant as input to a wrapper.

Subject: [PATCH 17/23] feat(harness): build the flat command index and expose
 it on the envelope lane
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

buildCommandIndex() projects the registry into the one flat namespace the
palette renders: commands, their verbs, verb-dispositioned flags, and
user-invocable skills, 50 rows on the current tree.

Every row carries the argv it resolves to as structured tokens rather than
a string to be munged at render time, so resolveArgv(row, values) produces
the exact command for the ledger echo. Value-taking flags become slots;
dependent options attach as refinements instead of appearing as rows.

A verb-dispositioned flag scoped to declared verbs emits one row per verb
carrying the subcommand token, so knowledge prune merged resolves to
['knowledge','prune','--merged'] rather than a form the handler ignores.

Skill names that collide with command names keep both rows — the command
owns the bare label, the skill is always skill:<name> — and the overlap is
reported rather than left implicit. A repo with no .github/skills yields
commands only; read paths create nothing.

+/**
+ * Command index — the flat, searchable index the TUI command palette renders
+ * (docs/architecture/harness-cli-workbench.md §"Command palette").
+ *
+ * The palette is an index OVER the registry, never a second command grammar:
+ * this module reads lib/registry.mjs's entries and projects them into rows,
+ * and the CLI grammar is untouched. Three properties of that contract drive
+ * every decision below.
+ *
+ * 1. ONE FLAT NAMESPACE. A command, each of its verbs, and each user-invocable
+ *    skill are sibling rows. Reaching a capability never requires knowing its
+ *    parent — `structural` is findable without knowing it lives under `index`.
+ *    That is why this is a flat array and not a tree keyed by command.
+ *
+ * 2. NO `--` IS EVER TYPED. The index carries options so a capability can be
+ *    *found*; it must never require one to be *written*. Hence `argvTokens`:
+ *    every row states, as data, the argv the CLI already accepts. The palette
+ *    resolves a row by walking those tokens (`resolveArgv`), never by parsing
+ *    its own label back into flags — a label is a display string, and
+ *    reconstructing argv from it at render time would put the palette's
+ *    formatting in the dispatch path.
+ *
+ * 3. ANNOTATION IS OPTIONAL, NOT ASSUMED. `verbs`, `surfaces`, `userInvocable`
+ *    and the per-flag `tui`/`requires`/`verbs` metadata are being populated
+ *    entry by entry. Every read here is defensive (`entry.verbs || []`), and
+ *    an un-annotated command still yields a row — the registry's own default
+ *    is "discoverable", and forgetting to annotate must never silently remove
+ *    a capability from the palette.
+ *
+ * Purity: same registry + same skills directory ⇒ byte-identical index. No
+ * model call, no network, and — per the harness read-path invariant — no
+ * directory or file is ever created. Filesystem enumeration order is never
+ * trusted; skill directories are sorted explicitly before any row is built.

Subject: [PATCH 18/23] fix(harness): keep a verb reachable when its dependency
 is its own parameter
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

isVerbFlag treated any tui:'verb' flag carrying requires as a refinement,
but requires points in two directions and only one of them means that.

--since requires --structural points up at another verb flag, so since is
correctly a refinement of index structural. --apply requires --ops points
down at its own prompt parameter — apply IS the capability and --ops is
the value to ask for. Treating them alike dropped consolidate apply out of
the index entirely, leaving it findable only by knowing to look under
consolidate, which is exactly what the flat namespace exists to avoid.

A verb flag's own requirements are now hoisted to the front of its prompts
and marked required, so the picker asks for --ops before dispatching a
combination validateArgs would reject.

Subject: [PATCH 19/23] test(harness): prove the command index cannot drift
 from dispatch

44 tests across four files covering AC8, AC9, and AC10.

The load-bearing one sweeps every row on every surface and asserts the
argv round-trip in both directions: each row's argv[0] is a registered
command, the bare template validates unless it carries an unmet requires
dependency, and the fully-answered argv always validates. Counters assert
non-vacuity so the sweep cannot pass by covering nothing.

AC8 re-derives capabilities from each entry's usage: prose and fails when
one is not also declared as data, so a new prose-only verb breaks the
build. AC9 asserts every rejection carries E_USAGE and exit 2 rather than
merely throwing, and pins that commands declaring no verb metadata still
validate exactly as before. AC10 pins envelope key order and asserts the
CLI branch output parses and matches the in-process envelope.

Also covered: determinism via serialized comparison, no label containing
flag syntax, collision policy for consolidate/recall, degradation when
.github/skills is absent, and that a read creates nothing on disk.

+/**
+ * AC9 — applicability. `validateArgs` must reject an option applied to a verb
+ * that does not accept it, and a dependent option whose requirement is absent.
+ *
+ * Both are the parser half of the palette contract: the index only offers
+ * combinations the CLI accepts (asserted in command-index-contract.test.mjs),
+ * and this file asserts the CLI actually refuses the combinations the index
+ * declines to offer. Every rejection is the `E_USAGE`/exit-2 class — "you
+ * called it wrong" — never a bare Error that bin/harness.mjs would misreport
+ * as a harness fault, so the code AND the exit are asserted, not just that
+ * something threw.
+ *
+ * Also covers `registerCommand`'s registration-time validation of the same
+ * metadata: a `requires` or `verbs` scope naming something undeclared can
+ * never fire, so it is a typo and must fail at registration rather than
+ * silently never applying.

Subject: [PATCH 21/23] fix(harness): show each palette row's own consequence,
 not its policy maximum
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A command's sideEffect is the maximum across every form it can take, which
policy must assume — report is mutate because --sync writes. The palette
inherited that verbatim, so index status rendered as a write despite its
own description saying 'read-only ... never rebuilds', and bare report and
consolidate did the same.

The glyph is the one claim this palette makes that no surveyed agent CLI
can: see what a command does to your repo before running it. It is worth
nothing if it over-warns, because a glyph that cries wolf stops being read.

Adds bareSideEffect on an entry and sideEffect on a flag, both validated,
both optional, both defaulting to the existing classification. Annotates
the five read-only forms that were mispainted. Policy classification is
untouched.

The accompanying test asserts both directions and fails any row that reads
weaker than its command without the registry explicitly declaring it — the
asymmetry matters, since under-warning is a safety bug where over-warning
is only a trust one.

Subject: [PATCH 22/23] fix(knowledge): stop CRLF silently erasing learning
 frontmatter
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

parseLearningFrontmatter's opening match tolerates CRLF, so a CRLF file
gets past it and then loses every scalar field: the block is split on '\n',
leaving a trailing carriage return on each line that the scalar matcher
cannot match, since '.' excludes \r and '$' without the m flag is
end-of-input.

The loss is silent. A learning still lists, because its id comes from the
path — but status, source, trigger, schema and episode citations are all
gone, so a retired learning reads back as active and the next write commits
that loss.

On Windows it fires after any store rollback (git reset --hard) or residue
discard (git checkout -- <path>), because the store repo is created with
git init inheriting ambient config and core.autocrlf=true is the
Git-for-Windows default. Reproduced by parsing the same frontmatter with
both line endings.

Splits on /\r?\n/ and pins the store repo to LF at creation. The pin is
config-only: a .gitattributes would need the lock-protected writeStoreFile
path, and the parse fix already stands alone.

The repository gains a .gitattributes pinning eol=lf. Every tracked text
file is already LF in the index, and production code defends with \r?\n in
14 places — that defensive pattern is the symptom of the missing pin.

Subject: [PATCH 23/23] fix(harness): close the Windows and adversarial-review
 defects
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Windows (from a real windows-latest run, 21 failures):

- the cancellation probe never tested cancellation. Its child used Windows
  timeout, which exits instantly when stdin is redirected, so it settled at
  75ms against a 1200ms abort and the runner correctly reported failed. The
  probe now uses node for both platforms, spawns a real grandchild, and
  asserts the settle time and the grandchild's death so an instant exit can
  never pass again. No runner bug existed.
- git-context compared a short 8.3 path against git's long form; realpath
  does not expand 8.3 names, so both spellings survived unchanged.
- a 228-character branch name exceeded MAX_PATH, git checkout failed, and
  the helper ignored the exit status, so layer routing silently ran on the
  default branch. The helper now asserts the checkout.
- SIGINT is not deliverable to a child on win32; the test now reproduces
  the in-process dispatch a real Ctrl-C performs and keeps every assertion.
- a path containing " -> " cannot exist on Windows; the mis-split rule
  stays covered by the parser test on every platform.
- explicit env is not merged by the harness — libuv copies a fixed list
  into the child. The assertion now uses a sentinel that no platform
  injects, so a real merge still fails everywhere.

Adversarial review (Codex):

- a row labelled read could resolve to a write: an orphan refinement
  attached --apply to bare consolidate. Orphans are now only flags with no
  row anywhere, and refinements carry their own side effect.
- required positionals never reached rows, so learning confirm and knowledge
  commit could not be completed into a runnable command.
- the round-trip test checked only the metadata that generated the row; it
  now runs dispatch's requireArgs gate and proves each downgrade is
  justified rather than merely declared.
- --apply=false was newly rejected; presence detection now agrees with how
  handlers actually read booleans.
- registration now rejects any side-effect override above its entry's class.
