+### 2026-04-24 — cluster 17 tell semantics (blocked, reverted)
+- Attempted: drop the `me` shadow from `tell X` compile so `add .bar to me` preserves original and `put your innerText into me` writes to original. Fixed tests 2 and 3 but regressed 4 others (`restores a proper implicit me`, `works with an array`, `establishes a proper beingTold symbol`, `ignores null`) which require bare commands like `add .bar` (no explicit target) to use the told as default. Reverted per abort rule. Proper fix needs a distinct `beingTold` symbol with compiler rewriting bare commands to target `beingTold-or-me` while leaving explicit `me` alone — >30min cluster budget.

 ### 2026-04-24 — cluster 15 transition query-ref + multi-prop (partial +2)
 - **3d352055** — `HS: transition query-ref + multi-prop (+2 tests)`. Three parts: (a) parser `collect-transitions` recognises `style` tokens (`*prop`) as a continuation, so `transition *width from A to B *height from A to B` chains both transitions instead of dropping the second. (b) Mock `El` class gets `nextSibling`/`previousSibling` (+ `*ElementSibling` aliases) so `transition *W of the next <span/>` can resolve the next-sibling target via host-get. (c) Generator pattern for `const X = await evaluate(() => { const el = document.querySelector(SEL); el.dispatchEvent(new Event(NAME, ...)); return ... })`; optionally prefixed by destructuring and allowing trailing `expect(...).toBe(...)` junk because `_body_statements` only splits on `;` at depth 0. Remaining `initial` test needs `on click N` count-filtered events. Suite hs-upstream-transition: 13/17 → 15/17. Smoke 0-195: 162/195 unchanged.
