Canvas union a57c334 source-review archive
This immutable source-review snapshot supports combined source commit a57c334b302eb13352b4bb65df1c75d94d002348, selectively integrating 42 source files in the isolated canvas worktree. Baseline: 32334c66317692befb6517a917dc7ae90641c11a with production 865483b4c66361a01fe0d9e731859220bafb4136. Peer: a31b40d0f8551ed87c8cd66250b9afb4809b3a79.
The seven payloads preserve six private source/review reports plus the frozen build-input manifest. manifest.json maps every original main-checkout private path to its archive path, byte size, original SHA256 and copied SHA256. Original report text and private references remain unchanged; use that mapping to resolve archived references without assuming private files exist on another host. readback.json independently rereads originals and copies and records the second comparison.
Root reported verify-head PASS at 2026-09-11 19:44:32 UTC: all 529 raw input files, 9,712,849 bytes, matched a57c334 Git bytes. The archived inputs.json SHA256 is 47FEC9CADC0E7FAE99D789376C111C02EEAAB7FAC3740DE48174A06F61FE16B3. Its original capture at 19:42:03 UTC describes an uncommitted candidate; that historical wording is preserved. The later root equality result establishes the commit mapping. This archiver verified the manifest payload and its 529-entry/byte totals; it did not independently rerun the source-to-Git equality check.
Review order and scope:
next-integration-865483b-review.md: historical preflight, exact peer/source boundaries and risks. Later work supersedes its pending integration status.canvas-prerequisite-union-report.md: implemented App/chooser/form/session/workflow union, preserving child-work and corrected source cards.canvas-pan-independent-review.md: independent pre-implementation transform and clipping obligations; not a final-candidate verdict.canvas-renderer-union-report.md: B4/pan implementation and preservation checks; its pending-review wording predates the final reviews.canvas-root-prerequisite-final-review.md: no actionable finding in the reviewed App/root prerequisite union; exact source hashes.canvas-renderer-final-review.md: no material finding in three frozen renderer files, preserving the distinction between arithmetic/Program tests and native pixel evidence.
Peer a31's 729 tests and strict Clippy were already closed; they validate a31, not this union. Root separately reports newer allocation-planner 29 tests passed, with its UI still unaccepted; that separate contribution is not accepted by this archive. Other historical preflight readiness statements remain scoped to their observation time.
This is source evidence only. At handoff, focused Windows compilation was running and no combined test result existed. Root will archive closed gates and add the source-version record separately. No build, test, compiler, GUI, WSL, Git/index or Gitea operation was performed to create this archive. Raw-input ZIPs, temporary source reconstructions, live logs, binaries, package payloads and unrelated private work are excluded.
