+# REL-02 checkpoint: register the 21 library build candidates
+
+All 21 libraries now have actual target-major tarballs and build evidence in
+`refactor/release-ledger.json`. They were prepared from committed source
+`1b8188834768605f312a5ed14dab52d75b9c880c`, after the validation-input and Yarn
+directory fixes. VitePress still has no site candidate. This checkpoint does
+not complete REL-02 or authorize publication.
+
+The 20-package `yarn test:package --browser` preparation passed in 103.26
+seconds. It built in a separate snapshot and verified archive contents,
+isolated installation and a frozen consumer lock. Its actual fixture scope
+was core/Chapter (36 runtime checks, 5 legacy and 8 accurate type modes) plus
+Audio/HLS installed type fixtures. Thumbnail 5.0.0 was built separately and
+its historical/candidate 12-case installed type command passed in 12.32
+seconds. The historical Thumbnail workspace fixture is not a recovered npm
+archive and does not close the missing rollback distribution.
+
+The candidate provenance collection checked 1,918 library input files against
+the before/after reports and current raw bytes, 1,041 retained build snapshot
+files against the normalized input hashes, and all 299 tarball members against
+their recorded hashes and build files. The 20-package installed copies were
+also compared with their archive members. No library fingerprint changed
+during these builds. Each candidate records its exact path, version, SHA-512,
+source commit and input fingerprint; the build envelopes retain the actual
+reports, logs, frozen locks and archive hashes.
+
+The actual installed browser map then passed 36 focused tests in 51,651.034 ms
+with zero failures, skips or retries: 24 Danmuku native sampling/eligibility
+cases and 12 Audio held-switch cases. Observed desktop engines on Windows were
+Chromium 153.0.8010.12, Firefox 155.0 and WebKit 26.6. Their reports and input
+map were archived before another run could overwrite them. This focused run
+does not close native starvation, full package combinations or physical Safari
+and mobile-device requirements.
+
+See [candidate preparation](../baselines/major-candidate-preparation.json)
+for exact inputs, candidates and browser evidence, and the `major-candidate-build/`
+directory for each build envelope. A fresh ledger calculation accepted all
+21 candidates and build envelopes with no stale fingerprints or candidate
+errors. Strict preflight for core still exited 1 with 28 blockers, as expected:
+registering build evidence does not bypass the remaining gates.
+
+The local registration check is retained at
+`refactor/.cache/release-ledger-eKfUln/report.json`; the strict core rejection is
+at `refactor/.cache/release-ledger-EG5WGs/report.json` with its command log in
+`refactor/.cache/rel02-registered-preflight.log`. These are observed checks of
+this binding state, not promises that future input changes remain accepted.
+
+Only the build gate is registered. Earlier package-specific type/runtime
+reports remain scoped observations; they were not copied into gate envelopes
+to imply complete validation of these exact tarballs. The remaining runtime,
+types, combinations, browser, devices, licenses, rollback, remote CI and three
+formal review gates stay explicit. Formal reviews wait for the user's direction.
+
+To continue, use the registered archive paths and the 20-package browser map
+in the preparation record. Preserve the ignored cache directories referenced
+by the envelopes: losing or changing them invalidates the bindings. Source,
+validation input or dependency changes require fresh candidate preparation;
+do not patch fingerprints onto old reports. The existing old-version rollback
+records remain unchanged. Reverting this checkpoint removes the local candidate
+bindings and build envelopes without changing any package implementation.
+
+No production source, public declaration, dependency or npm entry changed in
+this registration checkpoint. No push, remote dispatch, deployment or npm
+publication occurred. REL-02 remains doing; complete combinations and actual
+candidate rollback still require work.
