+**Session activity:**
+- feat(doctor): wired lib/doctor-cache.zsh into legacy GitHub token validation — fingerprint cache key (sha256 prefix of token, 1h TTL), `--no-cache` flag, JSON envelope `{http_code, username}`
+- refactor(doctor): extracted `_doctor_check_github_token(no_cache)` helper; doctor() now dispatches via one line; helper is independently testable
+- test isolation: `DOCTOR_CACHE_DIR` exported pre-source (cache lib marks it readonly post-source)
+- tests: +4 functions calling helper directly (not full doctor) — cuts test runtime by ~14s
+- empirical timing: cold flow doctor 11.3s → warm 10.8s (~5%, smaller than orchestrate estimate because `_dots_doctor_integration` was already provider-cached)
+- result: 53 test files pass, 1 expected interactive timeout; test-doctor 25s standalone, exit 0 under `timeout 30`
+- discovered (filed): test-framework `create_mock` save/restore is broken for binaries — `tail -n +2` strips opening `{` but keeps closing `}`, eval parse error on second mock
+- discovered (filed): `_doctor_cache_acquire_lock` mkdir-fallback leaks state across in-process invocations; cache_set rc=1 on second call with same key
+
+**Correction (2026-05-13):** Commit `0880f924` (first push of this branch) introduced a test-doctor timeout regression that the commit message and .STATUS both misreported as "52/52 passing". Run-all.sh actually reported "2 timeout" — only one (e2e-em-dispatcher) is documented as expected; the other was test-doctor running ~40s standalone under the 30s `timeout` wrapper in `tests/run-all.sh`. Caught during the optional Step 4 follow-up review when re-checking `time timeout 30 zsh tests/test-doctor.zsh`. Fixed in the follow-up refactor commit by extracting `_doctor_check_github_token` so cache tests skip the slow system-check section.
+
+**Previous Session (2026-05-13 earlier):**
+- fix(tests): test-doctor timeout under run-all.sh — cached `doctor --verbose` output in setup() and reused for both `--verbose` and `-v` tests (which test identical output since `-v` aliases `--verbose` per commands/doctor.zsh:39)
+- root cause: 3 redundant `$(doctor ...)` calls in test, each hitting `curl https://api.github.com/user` for ~5-8s of network wait
+- timing: 38.86s standalone → 23.51s wrapped (40% reduction)
+- result: 23/23 passing, exit 0 under `timeout 30 zsh ...`

+- `.github/workflows/test.yml:39-44` runs only `test-flow.zsh` + `test-install.sh`
+- Comment is explicit: "Smoke tests only - run full suite locally with: `./tests/run-all.sh`"
+- The required status check "ZSH Plugin Tests" on `main` therefore does NOT verify the 205-file suite
+- Surfaced during PR #446: the test-doctor regression from commit `0880f924` would have passed CI green despite test-doctor exiting 124 under the harness
+- Impact: relies on developer discipline to run `./tests/run-all.sh` locally before opening PRs
+- Options to consider: (B) add `test-doctor.zsh` specifically (~30s job time), or (C) add full `./tests/run-all.sh` as a separate slower job (~4min). Either is a separate workflow PR, not bundled with feature work

-1. Profile `test-doctor` >30s timeout (passes 23/23 standalone, but `run_test`'s 30s ceiling fails it under run-all.sh)
+1. Optional follow-up — drop `CACHED_DOCTOR_VERBOSE` workaround from test-doctor.zsh setup() now that the production cache also benefits second invocations

+## [7.7.0] — 2026-05-15 — doctor cache + zsh-scope hardening
+
+### Added
+
+- **`flow doctor` GitHub token validation cache** — Subsequent `flow doctor` invocations within 1 hour skip the GitHub `/user` API call (~5–8s saved per warm run). Fingerprint-based cache key (sha256 prefix of token) auto-invalidates on rotation.
+- **`flow doctor --no-cache`** — Bypasses the cache and forces a fresh API validation. Useful when troubleshooting "why is my token broken?".
+- **Regression test: `tests/test-readonly-scope-regression.zsh`** — Five-test guard preventing reintroduction of the bare-`readonly` zsh scope trap, including a functional proof that the bug still exists in current zsh.
+
+### Fixed
+
+- **doctor-cache silent write failures** — Module constants in `lib/doctor-cache.zsh` were declared with `readonly` instead of `typeset -gr`. When the lib was sourced from inside a function (e.g., a test harness `setup()`), zsh treated the `readonly` declarations as function-local; they vanished when the caller returned. The persistent load-guard then suppressed re-initialization. Symptom: `max_attempts=$((DOCTOR_CACHE_LOCK_TIMEOUT * 10))` evaluated to `0`, the lock-acquire loop ran zero iterations, and `_doctor_cache_set` failed with "Failed to acquire cache lock for writing." Production was unaffected (top-level sourcing keeps globals); only test harnesses surfaced the bug.
+- **Preventive: same fix in `lib/analysis-cache.zsh` and `lib/macro-parser.zsh`** — Same pattern, not yet bitten in practice. Switched to `typeset -gr` (and `typeset -gar` for arrays).
+- **`create_mock` save/restore destroyed originals** — `tests/test-framework.zsh` used `whence -f $fn | tail -n +2` to capture function bodies, but `tail -n +2` left the trailing `}` in the body. Wrapping it in a new `funcname() { ... }` template produced unbalanced braces and a silent eval parse error. The save failure cascaded: `reset_mocks` couldn't find the saved original, fell into the `unset -f $fn_name` branch, and **destroyed the real function**. Replaced eval-string round-tripping with zsh's `${functions[name]}` associative array — saves the body without surrounding braces and restores losslessly.
+
+### Changed
+
+- **Removed `CACHED_DOCTOR_VERBOSE` workaround** in `tests/test-doctor.zsh` — The doctor cache wired in the previous PR already deduplicates `doctor --verbose` calls via the disk-shared fingerprint cache. The setup-side cache became redundant. Side benefit: `test_doctor_v_flag` now actually exercises the `-v` alias instead of re-checking the cached `--verbose` output.
