Bounded new Platform review of source candidate manifest `8d345bb2bde3efce4d0cc99dfc2f883a64f79c42d2cd4abb288229a995e9ad66`: official zlib package/index provenance, exact current763c base and minimal layer/runtime changes, local scan/SBOM proof, source-pinned ownerCI publication/credential boundaries. Distinct from completed purpose-actuator RPF-IN-0007 and its approvedR2 trial. No native rollout/data action, owner source write, registry publish or carried-forward human approval. Native763c still has disclosed inheritedMEDIUM/T05 dueOct18; source candidate is unpublished. This owner work record precedes formal review.
## Completed initial source review
Initial technical review `RPF-REVIEW-20261011-INFD-ZLIB-CANDIDATE-R1` validates exact27-path8d345 source/localproofs and publication owner boundary. Source proof helper must refuse optimized Python before artifact IO; directory coverage verified independently for current artifacts and required on actual published readback. Four source methods pass; raw scans confirm base1MED/candidate0 on stated DB. Current local candidate remains unpublished; no native authorization transferred. Review refinement remains in promoted INFD-WP-0009-T05, separate from unpromoted verifier residual and completed IN7. Completed owner work record precedes formal entry.
## Completed amended-source review preparation
Same bounded review completed against the amended source. Exact initial conditional source review and four-file workrecord/probe snapshot are archived under `initial-380c6172`; initial failed optimized-proof boundary remains historical. Seven maker tests and independent optimized/deletion boundary probes reviewed. This completed workrecord is staged before the final formal review. Published-image readback and separate native authorization remain outside this source review.
## Completed final exact-source review
Final frozen66-path source `3e41ab391cda26f09a556fecef8a17c2759ef2899e43eb136b25ef4b3fde23a0` completed after optimization, directory metadata and whiteout-boundary refinements. Eight maker tests and five independent synthetic boundary probes pass. All66 hashes match. Actual existing local candidate remains unpublished with unchanged two-file delta,313 directory records and stated scan snapshot. This workrecord update precedes the formal narrow-source agreement; original380c conditional and645 failed proof-boundary evidence remain archived. No native result, approval, publication or T05 completion is recorded.
## Completed lower-layer-only whiteout refinement review
Same IN8 preparation trial completed against frozen74-path source `724aa4777eb1c8976d868e5f504473f4b6d58f13d750d87aefa5c8d5ca0747ec`. Whiteout markers now mask prior-layer state before merging current additions. Nine maker tests and thirteen independent CLI probes pass, including eight root/nested regular/opaque whiteout order variants that check the actual emitted replacement-file hash. All74 hashes match; existing local candidate remains unchanged/unpublished. Exact preceding16-file agreement snapshot and manifest/map are archived at `accepted-66-6af44c10` before supersession. This completed anchor precedes formal review and does not create a new success or native authority.
