+# REL-02 checkpoint: refresh candidates after shared tooling changes
+
+Rebuilt and packed all 21 libraries from clean commit
+96962a69a4faaecd986387efadb54c5623a23f2c after the Markdown chunking fix and its
+regression tests invalidated shared input fingerprints. The site candidate is
+still separate and absent. Previous archives, build envelopes and reports remain.
+
+The normal package runner prepared 20 libraries in a new build snapshot and
+installed their actual tarballs outside the workspace. Thumbnail was separately
+rebuilt and checked by its existing installed-package runner. No publication,
+remote workflow, dependency or additional source change occurred.
+
+## Evidence
+
+- Strict toolchain check: Node 24.21.0, Yarn Classic 1.22.22, 22 workspaces,
+  40 pinned tools and 1472 dependency selectors. No root lockfile change.
+- 1918 unique library inputs match before/after reports and current raw bytes;
+  1041 copied snapshot inputs also match their normalized source hashes.
+- All 299 archive members match the fresh build and isolated installed copies.
+  Compared with the previously registered candidates, no shipped member changes.
+  Target major versions and CHANGELOG files were checked individually.
+- The 20-package run passes 36 runtime observations for core/Chapter, five root
+  declaration compiler modes and eight accurate-runtime compiler modes. Installed
+  Audio/HLS fixtures pass their five compiler modes with negative-use checks.
+  Runtime/type checks for core/Chapter do not stand in for every plugin's behavior.
+- Thumbnail passes seven candidate compiler modes and root/legacy CJS/ESM import
+  checks. Five frozen-workspace cases retain expected missing-declaration errors;
+  that fixture is not the unavailable original npm archive or a rollback pass.
+- Both consumer flows complete offline installation followed by a frozen install
+  without changing their consumer locks. Package run:123.16s. Thumbnail production
+  build:4.22s; installed consumer runner:13.87s.
+- The registration check accepts all 21 new build envelopes, with zero stale
+  build fingerprints. Other release gates remain blocked. Old browser reports
+  were not reattached to the new candidate bindings, even with identical members.
+
+See [preparation](../baselines/shared-tools-candidate-refresh.json) and
+[registration check](../baselines/shared-tools-candidate-refresh-check.json).
+The proof records each prior and replacement candidate/build reference, exact
+file hashes, compiler observations and retained input/install logs. Ignored cache
+artifacts must remain available for those references to validate.
+
+REL-02 stays doing; totals224/22/39 remain unchanged. Continue remaining core
+documentation/implementation checks and package-specific release blockers.
+Formal REVIEW-01/02/03 remains user-directed. Revert this checkpoint to restore
+the previous ledger references; their pre-tooling input fingerprints stay stale.
