Fixes #728's acquired-address collision and saved SITE-free aggregate publication/reload. Exact qualified head 2f4c68ff05876efb48e14743ac8027064b1b09ab is now installed/public accepted on a distinct original receiving13 case. This is synthetic engineering acceptance, not biological accuracy or every checkpoint-metadata contract.

Existing owners and deleted competing decisions

• RuntimeArtifactMaterialization no longer addresses a record by shared memory location. Artifact-named output consumes its full original runtime scope; explicitly source-named writers retain original source identity.
• PlateImageInventory no longer overwrites admitted source metadata with filename coordinates. SITE-free source metadata survives saved inventory and streaming; ordinary unbound files still use their original filename parser.
• No duplicate publisher, identity store, codec, fixture-name workaround or guard relaxation. The source repair deletes six net production lines.

Normal integration includes main1715215f8 and merged743/744/753/759. The two repaired source owners are unchanged from the106-control checkpoint. No unmerged Root ancestry or private runtime stack is delivered through this PR.

Source evidence

106 affected source controls pass:79 materialization/address-family and27 inventory/reload, both SITE insertion orders, automatic/default and explicitly source-named writers, saved values, real TIFF loading, SITE absence, spacing and contributors. Focused before/after AST covers14 related owners/consumers,28 ASTs, no parse omissions; no global R1 claim. Original receiving12 failures remain intact.

Actual ordinary installed public path

Receiving13 original compilejob1 c141b006-4713-44ff-846f-357f8b7b0b0f, executejob2 4ffd2a7a-c02c-4590-b906-bcd2dfd4ed95: COMPLETE/errors[], allfour steps succeed. Original read-only installed checker3135 terminated0; actual exported typed runtime/artifact addresses and saved CSVs reconcile:

• Four acquired SITE1/3 × CHANNEL1/2 records preserve distinct CSV paths/full scopes and exact4×6 raw pixels.
• Default and explicit aggregate images preserve each channel's4×12/48pixels, address-bound table rows, true SITE1/3 contributors, Y.25/X.5µm calibration and absence of scalar SITE.
• The SAME owned viewer's ordinary saved image stream admits both channel images/errors[]. Actual native samplers prove all48pixels per channel11/13 and21/23, uint16 and SITE-free metadata/calibration.
• First saved screenshot retained as unsuitable because an older acquired route remained selected. Supported isolation selected selected_images CHANNEL2; Dewey and Planck personally opened the positive native screenshot with both halves and no saved scalar SITE. Older mounted acquired routes retain their genuine SITE axis independently.

Explicit limit: acquired checkpoint source_voxel_spacing is empty in this case. Aggregate calibration passes, but we do not claim every acquired checkpoint passed spacing. That separate pass-through gap is not hidden or repaired by this PR.

Exact native3293555/create1791205633.28 and viewer3510427/create1791207058.28 public close acknowledgments report all required closure fields true/errors[], independent PIDs/endpoints absent. Original MCP invocation inactive/dead. Post-writer complete journals are sealed; no execution or UNKNOWN replay, frozen output edits or substitute client.

Original failed receiving12 case remains COMPLETE execution but failed publication/reload, with its original logs/closures untouched. Current scientific prefixes/skill bundles are unchanged. #748's automatic fractional-Z point/volume-label case and Singer522 selected-source navigation remain separate. Hosted CI is deferred by the user; local/source and real affected installed path are demonstrated.

Retained assisted saved-label triage is published at c2dbfdf in the existing receiving receipt. Exact native6013.log43–58 names FIELD site5 labels, not the stitched mosaic. Original saved metadata declares SOURCE_BINDING with two DAPI/FITC source planes, empty contributors and no scalar CHANNEL; manual reopening preserves that plane domain and scalar-layer route construction refuses it. This does not establish that732 fixes saved-label reopening:732 scopes genuine contributor reduction at the publication adapter; the manual path bypasses it.407 is presentation-only. Existing152 producer-family ownership is coordinated directly with Planck/Dewey; Singer retains receiving integration. No competing patch, live replay, science mutation or guard weakening. The tiny saved-label control is a separately pinned producer acceptance alongside the shared receiving packet, not a new732 merge hold. Production/source41 qualification unchanged;732 ordinary installed default-publication acceptance remains pending.
