   This shipped already, so there is nothing new to build. Verified against main (973bad0); closing as completed.

   Where it landed. PR #53 (feat/issue-3-per-phrase-difficulty-tiers, merge 145b28b), commits 1ec8384 (pure planner), f8773e1 (command + keybind), with review follow-ups 32bdf23 / bb73aa3 / cdebe79. git merge-base --is-ancestor 1ec8384 origin/main → true.

   Acceptance criteria

   Criterion	Where
   Strictly simpler lower tier, full tier untouched	planTierSimplification in src/tiers.js:457 derives a rung one difficulty below the current floor; the top tier stays the editable flat chart (src/tiers.js:539-586). Thinning is deriveSimplifiedNotes (src/tiers.js:215: drop hammer_on/pull_off chains, strip bend/slide/tap to load defaults and null bend curves, drop positive sustains under half a local beat) plus deriveSimplifiedChords (src/tiers.js:283: dense chords thin).
   Undoable	SimplifyPhraseCmd (src/input.js:946) is executed through S.history.exec and holds the prior tiers/max_difficulty by reference for a verbatim rollback; the runner is _editorSimplifyPhraseAtCursor (src/input.js:1013). Refusals are statuses only and never enter the history.
   Tests cover the thinning rules on a fixture	tests/tier_simplify.test.mjs (planner refusals/sourcing), tests/phrase_tier_commands.test.mjs (exec/undo/redo), tests/test_phrase_tier_authoring.py.

   Verification run just now on HEAD

   • node --test tests/tier_simplify.test.mjs tests/phrase_tier_commands.test.mjs → 36 pass / 0 fail.
   • python3 -m pytest tests/test_phrase_tier_authoring.py tests/test_phrase_tiers.py → 29 passed.

   User-facing surface. Alt+P / Add ▸ Markers "Simplify phrase at cursor" (src/shortcuts.js:169, src/menu-bar.js:103), documented in README.md:132-138, docs/USER-GUIDE.md:404-407, and CHANGELOG.md:126-149.

   One scope bullet here — "choose the target tier (and see which tiers exist) from the phrase's context" — is not in this command: it always mints the next rung below the floor. That selection/listing UI is explicitly the subject of the still-open sibling 3/4 #35 ("Switch the editing view between a phrase's tiers", "Show which tiers a phrase has"). The acceptance criteria for this issue are fully met.
