 # Changelog
 
+## v3.3.0.1 (2026-08-05)
+
+To get this fix: `cd` into your idstack clone, then `git pull && ./setup`. Restart Claude Code afterward — plugins load at session start.
+
+### Fixed — skills no longer suggest commands that don't exist
+
+- **Welcome-back and next-step messages named unrunnable commands.** v3.3.0.0 banned bare `/skill` references because they resolve in neither CLI, and fixed them in `bin/idstack-status`. The guard enforcing it matched only backticked refs, so three plain-prose examples in the preamble's context-recovery section survived — and the preamble is spliced into all 22 skill files. The model copied their shape and told users things like "Based on your progress, /assessment-design is the natural next step." Typing that does nothing. Landing inside the context-recovery message v3.3.0.0 had just repaired made it the first thing a user saw once welcome-back messages started working again. Now namespaced; on Codex the existing translation rule renders them as `$<skill>`.
+
+### For contributors
+
+- The smoke-test guard now matches a bare `/skill` in any command position, not only inside backticks, and scans skill bodies with frontmatter still exempt (`description:` is picker prose, not a command). Suite count unchanged at 371.
+- `test/mutation-test.sh` gained a case that reintroduces an unbackticked bare reference into the preamble and asserts smoke-test fails: 14 mutations, 14 guarded.

 - course-quality-review, course-export, and learning-objectives now write their manifest sections through `bin/idstack-manifest-merge` (atomic, section-scoped, preserves every other section). needs-analysis and course-import keep the Read-modify-Write path — both write several co-owned sections in one pass, which whole-section merge cannot express — and each now documents why.
 - `bin/idstack-migrate --init` creates a canonical manifest with every section at its default. Three skills told the user to run `idstack-migrate` to create one when running standalone; it was a no-op on a missing file, so the merge that followed died with exit 4 and standalone results were silently never persisted. The skeleton comes from running the existing migration chain over a minimal seed, so there is no second definition of "canonical".
 - learning-objectives reports gained the required "Top recommendations" section; `[Alignment-1]` is now correctly cited as T5.
-- Logic that was duplicated or inlined and therefore untestable now lives in `bin/lib/` and is sourced by its callers: `version-classify.sh` (shared by `setup` and `bin/idstack-doctor`) and `plugin-status.sh` (the `claude plugin list` parser). Their unit tests exercise the shipped code rather than a copy — the version classifier had drifted across three PRs while a mirrored test passed green.

 The audit found the test suite had never run automatically, and that some of it was not testing what it appeared to test. Both are fixed:
 
-- **CI.** New GitHub Actions `test.yml` runs all seven suites on push and PR (ubuntu + macos, Python 3.9 + 3.12 — 3.9 is the leg that catches the context-recovery class of bug). `release.yml` refuses to publish unless the tag, `VERSION`, `plugin.json`, and `CHANGELOG.md` agree and the smoke test passes.
-- **`./setup` is now tested** — 16 behavioral tests covering flag parsing, scope selection, all three legacy-cleanup shapes, and failure handling, run against a repo copy with a fake `$HOME` and a stub `claude`. It previously had no coverage at all while the smoke test spent 14 assertions on landing-page CSS.

 - **A mutation suite proves the guards work.** `test/mutation-test.sh` reintroduces each of the 13 defects fixed here into a throwaway copy and asserts the guarding test fails. This is what was missing: the version-classifier suite passed green while testing a local copy of the classifier rather than the shipped code, and `gen-skills` counted a placeholder-less template as neither generated nor failed.
 - smoke-test grew from 272 to 371 assertions (version agreement, canonical section names, `/idstack:` namespacing, resolve-snippet lockstep, v1.1 migration, `bash -n` on every script) and prints failure diagnostics instead of a bare FAIL; integration-test proves it leaves the working tree untouched.
