TypeScript builds a synthetic signature for every JSX intrinsic element and
computes a module specifier for @types/react (index and jsx-runtime) per
importing file. computeModuleSpecifiers visits every symlinked location of
that file and scans all 491 tsconfig paths for each; pnpm gave 65 packages
their own node_modules/@types/react link. Client test-aggregate Check
followed 26.9 + 0.494 * N seconds for N locations.
- Remove @types/react and @types/react-dom from all 67 workspace manifests
and declare them once in the root devDependencies; packages keep declaring
the react and react-dom they import (ui-slots gains react).
- verify-package-dependencies rejects either package in any workspace
manifest and requires the root declaration, so a new package cannot add
the link back.
- packages/client/AGENTS.md states the rule.
Client aggregate Check 59.1 s -> 26.5 s; the 76 client-only package
projects 54-57 s -> ~44 s wall. File set (2,613) and diagnostics unchanged.

Merge master 62b700bba7bb71e66d2d5a3b850ba8f4dd0fd6b4 into release/session-log-v4 at 4825bc01a999f564e79172a6af28e34fc757c540. Preserve this pinned integration checkpoint before any later upstream movement so the dependent session-format repairs have an immutable rebase base.
Keep release projection-backed child catalogs, independent Session references, exact fork behavior, V4 writer, and existing migration data. Adapt the incoming subagent sidebar chat to refreshProjections rather than the removed dedicated catalog API, preserve title projections in complete projection fixtures, and retain both sidebar actions and release lineage/status behavior. Remove the duplicate SessionProjectionMap import introduced by automatic merging.
Preserve both disjoint archive seals without changing any existing hash. Regenerate current Cordis and documentation catalogs from the combined source, retaining release session methods plus master slot factories. The frozen V0-V3 runtime paths are unchanged. Initial validation passed the full build, 93 focused Client tests, and all 1905 archived artifact seals; remaining integration and snapshot checks follow on this checkpoint.
