…cript Collects every public API break between release-v14 and master into ai-docs/v15-breaking-changes.md (77 entries with evidence, coverage map and notes for the migration guides) and adds scripts/api-surface.mts (yarn api-surface dump/diff/check) to re-run the surface diff and the coverage gate against later release candidates.

Review comments at @scripts/api-surface.mts:
- Around line 780-782: Update the check logic to inspect result.moved and
require each moved export’s name to be mentioned in the audit document; add an
uncovered moved export to missing with its source and destination entrypoints,
alongside the existing removed-export checks.
- Around line 1087-1090: Update the package coverage loop in check to avoid
substring matches against the entire doc: require whole-word matches for package
names, and for changed entries require the package name and new value to appear
together in the same section. Keep the existing handling of added entries
unchanged.

… words check ignored exports that moved to another entry point, and matched package names with a plain substring search, so names like stream-chat passed against any migration doc. Moved exports must now be named next to their new import path, removed packages must appear as a whole word, and a changed range must be stated with its new value next to the package name.

Require the destination for moves to the root entry point.
When m.to is ., target is undefined. A section that only names the export then passes, even if it does not state that consumers must import it from stream-chat-react. Match the root package specifier in that branch.

Normalize export entry points before coverage matching.
dump records export keys such as ./obsolete, and diff emits them as exports:./obsolete. The check then searches for the literal ./obsolete, so documentation that names stream-chat-react/obsolete can be reported as missing.

Goal
v15 moves message, thread, composer and configuration state into
stream-chatv10, and much of the v14 public API changed or went away along the way. Before the stable release we need one audited list of every break in the public surface (exported components, hooks, contexts, utilities and types, plus package, behavior, CSS and i18n changes) to serve as the source of truth for the migration guides and the docs update.This is the base of a stack: the migration-guide alignment PR builds on it, and the dead-surface cleanup PR builds on that.
Implementation details
ai-docs/v15-breaking-changes.md: 77BC-###entries in the same format as the v13 -> v14 audit (ai-docs/breaking-changes.md), grouped by area. Each entry has the old API, the replacement, evidence (release-v14:andmaster:file and line, commit / PR, corpus errors) and docs impact. It also has a coverage map (every diff item, corpus error, guide heading and!commit mapped to an entry or ruled out), a pending section for feat: adopt TS generator changes #3306, the v14 fix that was never ported (fix: put unread separator above system messages and stop scrolling the host page on scroll to a message #3305), and notes on inaccuracies in the existing guides.scripts/api-surface.mts(yarn api-surface dump | diff | check): dumps every export of everypackage.jsonentry point from a checkout (kind, signatures, props and members with a fingerprint of referenced types, prop defaults, literal constant values, package metadata, CSS classes and custom properties), diffs two dumps, and checks that every gated change is mentioned in the doc. Re-run it against later release candidates; the doc's "How To Re-run" section has the commands.release-v14vsmaster), the 564 code blocks of the v14 docs plus the v14 examples typechecked against v14 and v15 (only errors new under v15 count), every commit and PR description since the branch point, and source review for behavior changes. Drafting was split by area, and every entry then went through an independent adversarial verification pass against both branches.api-surface checkreports every gated change covered, every "After" snippet in the doc typechecks against v15 in strict mode (apart from placeholder variables), andyarn types:scriptspasses.stream-chat(LLC) changes are out of scope and are listed as ruled out with a pointer.UI Changes
None. Docs and a dev script only.
