 - The T3 steps that read a thread or list threads state their own start, `limit` and `maxCharsPerItem`, so they read the same on T3 builds that differ in order and defaults (a read with no `afterPosition` returns the oldest items first on older builds and the newest first on newer ones; pingdotgg/t3code #33428): `rules/references/multi-agent.md` (the child check, the progress and end-of-thread reads, a finished child's result) and `hr-handoff`'s `references/successor-thread.md` (the header read for `projectId`, the list and the read-back after a settle). A header-only read is `limit: 1`, `maxCharsPerItem: 1`, `runLimit: 1`; the end of a thread is read from `afterPosition` max(0, `itemCount` minus 60), highest `position` newest.
 - `hr-sqlite`'s `references/evidence.md` adds a rerun of three measured rows (planner statistics after `PRAGMA optimize`, `synchronous` FULL against NORMAL, and `backup()` against `VACUUM INTO`) on Node 26.13.1 with SQLite 3.54.1. The first figures stay with their versions; the section says the new host, disk and data differ, so the gaps are not attributable to Node or SQLite. Planner statistics still fixed the query (20.4, 6.7 and 8.3 ms to 0.0059 ms); the `synchronous` gap is 7.5 times on this disk, not 87.
 - `hr-diagnosing-bugs`' `references/evidence-discipline.md` adds three rules for a chain of causes: label each claim measured, derived or inferred (an inference names the observation or report it rests on), test each causal link on timing, mechanism, magnitude and necessity (a case where the trigger fired without the cause, or a probe that removes it) and treat a refuted link as a dead theory unless a second cause could produce the same effect, and re-measure inherited numbers, with claims about people or ownership held to the same evidence as claims about systems. `SKILL.md` adds a stop rule for tracing a failure back cause by cause: stop at the step that names something you can change that would have prevented it (what produced a state that should never exist, or the code that mishandles a legitimate one), and merge steps past about seven.
+- The `hr-better-*` skills and `hr-explain-interface` move to jakubkrehel/skills `a72290d` (each upstream hunk judged): accessibility words the 2.2.2 timer rule as upstream does (auto-updating content needs a control however long it runs), keeps WCAG's limit to content shown alongside other content and its exemption for essential updates, and says a custom dialog must render outside the `inert` container; colors' `@supports` example uses the same `oklch` value as the first; typography's `text-box` examples name both edges (`trim-start cap text`, `trim-end text alphabetic`), because a one-edge `cap` or `alphabetic` value is dropped. Left out: upstream's `100dvh` keyboard note in layout (its "stable chrome" advice conflicts with the sticky-footer recipe here, which the keyboard still covers on iOS Safari), upstream's `hit-areas.md` label rule (already here) and its `explain-interface` token recipe (this fork reads themed and computed values its own way).

+- **Visible controls on anything that runs on its own** (2.2.2). Moving, blinking or scrolling content that lasts more than 5 seconds needs a pause, stop or hide control, muted looping hero videos included. Auto-updating content needs one however long it runs, and a frequency control satisfies it. Both apply to content shown alongside other content; an essential update, such as a progress indicator on a screen with nothing else, is exempt.
 - **Explicit dismissal over timers.** Auto-dismissal suits low-stakes confirmations and nothing else. A toast carrying an action, an error or information the user may need stays until dismissed.
 - **Pause on attention.** Where a toast must time out, give it at least 5 seconds, and pause the timer while it is hovered or focused.
 - **Never put critical information only in a timed element.** A vanished toast with the only link to an undo action is data loss on a schedule.
