 identity. Planck has the exact743 source/packet and closure handoff for the next
 ordinary whole candidate; immutable receiving12 must not be used as743 proof.

+Receiving13 ordinary prepared-source adjustment
+-----------------------------------------------
+
+Original95 source-plan refusal required writable plate_path; no compile or
+execution was submitted by that rejected request. Dewey staged three physical
+436-byte TIFF copies, byte-identical to the immutable original acquisition, at
+the already declared public01/execution-acquisition root. The successful normal
+source plan reports all three exact virtual/source mappings, aliases/channels,
+SITE1/Z1/T1 and relative1,1. It does not claim staged paths are original paths.
+Original complete replies remain in receiving13/public95/ADMIN743_95/
+author-workspace/output/runtime/mcp.stdout, including the refusal.
+
+The existing checker now takes the source plan's declared execution acquisition
+root as its fourth argument AFTER target/forwardVALUES/reverseVALUES. It hashes
+BOTH original and staged files against the same frozen three SHA256 values,
+checks native physical filter paths through SourceMetadataFields' original
+typed projection, and keeps exact native virtual-source/CSV identity checks.
+Receipt serialization uses the existing to_jsonable owner. No alternate codec,
+forged original paths, weaker numerical checks or product change is introduced.
+The complete pipeline documents and all expected numeric/source/coordinate
+relations are unchanged. This fixture-only adjustment does not require a new
+wheel or a repeat of source controls.
+
+Final original installed receiving13 acceptance
+----------------------------------------------
+
+This supersedes the earlier source-only disposition, without replacing original
+failures. The ordinary whole candidate source is2f4c68ff05876efb48e14743ac8027064b1b09ab,
+wheel SHA26cdc93a5a5fa5d4357e4e22f7592851a418c2b17abf253eaa6e20b0e221ec54,
+at /home/ts/wt/openhcs-issue-batch-20260929/engineering-pre-first-routing-20261004/receiving13.
+Planck's original READY/freeze qualifies the entire package; it is not a three-file
+overlay. Later invocation changes use the existing RuntimeSliceProjection owner,
+so whole invocation.py byte equality to historical484639 is not claimed.

+Process/Nuclear contributors, the original twelve-pixel values430/255 and889/255,
+their mean/max checks, exact native-to-CSV source names/channel/paths and relative
+1,1 calibration. Mask remains the separate image source. No common channel is
+fabricated. Both original and staged inputs match their frozen hashes.

+Dewey's exact native2674387/create1791202626.62 closed with typed ACK,
+endpoint_terminated/process_exited/succeeded true, errors[], and independent PID
+absence. No viewer started. Original sole client97761 EOF terminal1 is preserved:
+the existing shell aggregates earlier invalid-query/read-only workspace refusals;
+no later native/close failure is recorded. All three journals are sealed. The
+lease is returned for repaired732's separate incarnation, not silently reused.
+
+This closes743's installed/public scalar provenance boundary. The parent's
+distinct twenty-pixel case remains distinct, and neither case is biological
+accuracy or arbitrary heterogeneous stack acceptance. PR743 and issue742 were
+already merged/closed; this is durable receiving evidence, not another feature
+merge request. No package, test, native/client or scientific operation was rerun.
