+# Cached Repository State Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Make `no-mistakes status` always render cached, local-only repository branch evidence without adding a pipeline or network operation.
+
+**Architecture:** `internal/cli/status.go` already obtains `branchsync.State` through `InspectCached`. Add one small presenter for that state and render it unconditionally after repository discovery. Include the rendered cached summary in the existing status telemetry fingerprint so sampled status events correspond to visible state.
+
+**Tech Stack:** Go, Cobra, existing `branchsync.Service`, existing CLI test helpers.
+
+---
+
+## File structure
+
+- Modify: `internal/cli/status.go` - render cached evidence and fingerprint it.
+- Create: `internal/cli/status_test.go` - table tests for the pure cached-state presenter and fingerprint coverage.
+
+### Task 1: Write the failing presenter test
+
+**Files:**
+
+- Create: `internal/cli/status_test.go`
+
+- [ ] **Step 1: Define clean, dirty, and unavailable cases**
+
+```go
+func TestCachedBranchSummary(t *testing.T) {
+    tests := []struct { name string; state branchsync.State; want string }{
+        {"clean branch", branchsync.State{State: branchsync.StateSynchronized, Local: branchsync.LocalState{Branch: "feature/state", Head: "0123456789abcdef", Clean: true}}, "cached: feature/state 01234567 (clean; already synchronized with the pipeline-pushed head)"},
+        {"dirty branch", branchsync.State{State: branchsync.StateDirty, Local: branchsync.LocalState{Branch: "feature/state", Head: "fedcba9876543210", Reason: "uncommitted changes"}}, "cached: feature/state fedcba98 (dirty: uncommitted changes; dirty)"},
+        {"unavailable", branchsync.State{State: branchsync.StateAmbiguousContext}, "cached: unavailable (ambiguous context)"},
+    }
+    for _, tt := range tests { t.Run(tt.name, func(t *testing.T) {
+        if got := cachedBranchSummary(tt.state); got != tt.want { t.Fatalf("cachedBranchSummary() = %q, want %q", got, tt.want) }
+    }) }
+}
+```
+
+- [ ] **Step 2: Verify red**
+
+Run: `go test ./internal/cli -run '^TestCachedBranchSummary$'`
+
+Expected: compile failure because `cachedBranchSummary` does not exist.
+
+### Task 2: Add the local-only presenter and render it
+
+**Files:**
+
+- Modify: `internal/cli/status.go`
+- Test: `internal/cli/status_test.go`
+
+- [ ] **Step 1: Implement the presenter**
+
+```go
+func cachedBranchSummary(state branchsync.State) string {
+    summary := humanSyncSummary(state)
+    if state.Local.Branch == "" || state.Local.Head == "" { return "cached: unavailable (" + summary + ")" }
+    head := state.Local.Head[:minLen(len(state.Local.Head), 8)]
+    cleanliness := "clean"
+    if !state.Local.Clean { cleanliness = "dirty"; if state.Local.Reason != "" { cleanliness += ": " + state.Local.Reason } }
+    return fmt.Sprintf("cached: %s %s (%s; %s)", state.Local.Branch, head, cleanliness, summary)
+}
+```
+
+- [ ] **Step 2: Replace the conditional cached-state rendering**
+
+```go
+syncState := (&branchsync.Service{DB: d, Repo: repo, WorkDir: "."}).InspectCached(cmd.Context())
+cachedSummary := cachedBranchSummary(syncState)
+fmt.Fprintf(w, "\n  %s  %s\n", sDim.Render("local state:"), cachedSummary)
+```
+
+- [ ] **Step 3: Verify green**
+
+Run: `go test ./internal/cli -run '^TestCachedBranchSummary$'`
+
+Expected: PASS.
+
+### Task 3: Keep telemetry aligned with rendered evidence
+
+**Files:**
+
+- Modify: `internal/cli/status.go`
+- Modify: `internal/cli/status_test.go`
+
+- [ ] **Step 1: Add a failing fingerprint regression test**
+
+```go
+func TestStatusFingerprintIncludesCachedSummary(t *testing.T) {
+    run := &db.Run{ID: "run-1", Branch: "feature/test", Status: "running", HeadSHA: "head-one"}
+    before := statusFingerprint("repo", "running", run, "cached: main 01234567 (clean; synchronized)")
+    after := statusFingerprint("repo", "running", run, "cached: main 89abcdef (dirty; dirty)")
+    if before == after { t.Fatal("changing displayed cached evidence must change the status fingerprint") }
+}
+```
+
+- [ ] **Step 2: Verify red**
+
+Run: `go test ./internal/cli -run '^TestStatusFingerprintIncludesCachedSummary$'`
+
+Expected: compile failure until `statusFingerprint` accepts the cached summary.
+
+- [ ] **Step 3: Update signature and call site**
+
+```go
+fingerprint := statusFingerprint(repo.ID, daemonState, activeRun, cachedSummary)
+```
+
+Build the fingerprint from repository id, daemon state, cached summary, and
+the existing active-run fields. Update the existing active-run-head test with
+the fourth argument.
+
+- [ ] **Step 4: Verify focused tests**
+
+Run: `go test ./internal/cli -run 'Test(CachedBranchSummary|StatusFingerprint)'`
+
+Expected: PASS.
+
+### Task 4: Validate and prepare review
+
+**Files:**
+
+- Modify: `internal/cli/status.go`
+- Create: `internal/cli/status_test.go`
+
+- [ ] **Step 1: Add command-level status coverage**
+
+Use `setupTestRepo`, `executeCmd("init")`, and `executeCmd("status")` to
+assert the clean and a newly dirty worktree both retain `repo`, `daemon`, and
+`no active run` output and always include `local state:  cached:`. The clean
+case must include `(clean;`; the dirty case must include `(dirty:`.
+
+Run: `go test ./internal/cli -run '^TestStatusAlwaysRendersCachedLocalState$' -count=1`
+
+Expected: PASS.
+
+- [ ] **Step 2: Format and run full gates**
+
+Run: `gofmt -w internal/cli/status.go internal/cli/status_test.go && make lint && go test -race ./... && go build -o ./bin/no-mistakes ./cmd/no-mistakes`
+
+Expected: each command exits 0.
+
+- [ ] **Step 3: Inspect the review diff**
+
+Run: `git diff --check && git diff -- internal/cli/status.go internal/cli/status_test.go`
+
+Expected: no whitespace errors and no source file outside the planned scope.
+
+- [ ] **Step 4: Commit after fresh evidence**
+
+```bash
+git add internal/cli/status.go internal/cli/status_test.go
+git commit -m "feat(status): show cached repository state"
+```
+
+### Task 5: Review-remediation safety proof
+
+**Files:**
+
+- Modify: `internal/cli/status_test.go`
+- Modify: `docs/src/content/docs/reference/cli.md`
+
+- [x] **Step 1: Add a command-level cached-only safety regression**
+
+Run `status` after `init` through a test-local Git wrapper that records any
+`fetch` or `ls-remote` invocation. Snapshot `.git/FETCH_HEAD`, `.git/index`,
+refs, worktree state, and the gate database before and after the command.
+Assert that the command renders cached state, makes no remote Git call, and
+does not change any snapshot.
+
+- [x] **Step 2: State the user-facing freshness boundary**
+
+Document that the always-rendered cached local-state line is local evidence,
+does not fetch or query remotes, and does not assert remote freshness.
+
+- [x] **Step 3: Run focused and full verification**
+
+Run:
+
+```bash
+gofmt -w internal/cli/status_test.go
+go test ./internal/cli -run 'TestStatus' -count=1
+make lint && go test -race ./... && go build -o ./bin/no-mistakes ./cmd/no-mistakes && git diff --check
+```
+
+Expected: each command exits 0 before updating the PR.

+# Cached Repository State Design
+
+## Intent
+
+Rebuild the legitimate portion of the old fork's diagnostics intent on current
+`upstream/main`: make `no-mistakes status` always show the already-available
+local branch evidence that an agent needs before starting work.
+
+## Scope
+
+`status` will call the existing `branchsync.Service.InspectCached` once and
+render a clearly labelled cached summary containing the local branch, a short
+HEAD, clean/dirty state, any local reason, and the existing human branch-sync
+summary. Its telemetry fingerprint will include that rendered evidence so a
+meaningful displayed state change is observable by the sampled read surface.
+
+## Safety contract
+
+`InspectCached` is the data source because it explicitly does not fetch,
+contact a remote, alter refs, alter the index, alter the worktree, create a
+pipeline run, or mutate the database. The output must say `cached`; it must
+not claim current remote freshness.
+
+## Non-goals
+
+- No new pipeline step, daemon behaviour, schema, gate, worktree inventory,
+  remote inspection, or direct process execution.
+- No recovery or synchronization action from `status`.
+- No recovery of the fork's unregistered pipeline experiment or tracked binary.
+
+## Acceptance criteria
+
+1. A registered repository's `status` output always includes cached local
+   branch evidence, including an explicit unavailable form when Git evidence is
+   absent.
+2. A clean and a dirty local state render distinguishable, actionable text.
+3. A change to rendered cached state changes the status telemetry fingerprint.
+4. Existing status behaviour for repo identity, daemon, and active-run display
+   remains intact.
+5. `gofmt -w .`, `make lint`, `go test -race ./...`, and
+   `go build -o ./bin/no-mistakes ./cmd/no-mistakes` succeed before review.
