Unify current photograph selections and regenerate access views

Publish one authoritative work-level selection registry for the existing 435 selected fronts, with exact source/download/display identities. Rebuild the work table, recording-photo tables and download indexes; preserve all existing photograph choices, original media and Work_Images authority. Current views cover 1,256 linked recordings; 183 unlinked rows retain null images. Companion and browser refresh follow the accepted source revision. Visual-quality review remains separate.

 The [October 26, 2026 verification record](verification/2026-10-26/README.md) extends the earlier 557-renamed-file check to the explicitly inventoried public archive destinations across the canonical archive and its two linked access repositories. It includes current media, Parquet access containers, declared historical media links, candidate sources, and sealed source-index destinations at their documented revisions.
 
 The repeatable [checker](../tools/verify_public_access.py) and dated receipts retain failures, retries, exclusions and source pins. This is maintainer-run access and identity-metadata verification. Bounded byte delivery does not establish complete large-file fixity, playback, capture dates, temporal alignment or relationship truth. Proposed and candidate evidence remains qualified.

+The generated-access-table receipt and its path-only validator preserve the

+tools/build_photo_selection_views.py --check. Hash-addressed display JPEGs in

-
-This source-resolution master download set covers **all 435 active registered works** after the [direct creator confirmation of the July 25 drawing](../../Work_Identity/Confirmations/2026-10-25-july-25-two-stages.md). The two July 25 recordings show the same physical drawing in two stages. The 10:17 work ID remains active; the 19:16 ID is retained as superseded. Both recordings and their history remain preserved. These are work-level photograph counts, not counts of recordings.
-
-The prior 431-entry master index contributes 430 unchanged entries after retiring the duplicate July 25 entry. Five newly owner-confirmed front photographs complete the 435-work set; those additions cover 51 associated recordings. Every current master row has a distinct work ID, image path and JPEG SHA-256. The redundant current JPEG path is removed; its exact source binding, previous row and surviving photograph are retained in the retirement receipt and immutable repository history. Original photographs remain unchanged.
-
-Resolution classes are **159 native-resolution JPEGs**, **274 limited-resolution JPEGs**, and **2 supplied-source-resolution JPEGs**. Completing work coverage does not make all photographs native high resolution. Native pixel dimensions do not guarantee fine-detail legibility or calibrated color. Limited-resolution files without a color profile are interpreted as assumed sRGB; this is an explicit interpretation, not measured source calibration. Embedded profiles remain authoritative when present.
-
-The 430 surviving earlier entries keep their source/display hashes and download URLs unchanged. They reuse 355 previously published images and 75 JPEGs already in this directory. The five new 6048 × 8064 rendered JPEGs are bound to exact DNG source hashes and the creator's A–E confirmation. Their HF small-display derivatives have not been generated, so display_sha256 is null/blank for those five. The separate small-display companion has its own selection and regeneration lifecycle: after the identity correction it covers 430 active works, with those five still absent.
-
-## Revision resolution
-
-The 430 surviving earlier CSV URLs remain pinned to media commit 07df3064092099b5c97c8a4f54685b1a931d9f22. The five new URLs use versioned release ref master-fronts-435-2026-10-25, which must resolve to the same single commit containing these files and indices. The release receipt records its exact commit SHA. Publish the commit and matching ref together; do not move the ref after release. This avoids a second indexing commit and does not apply the old media commit to files that were absent there.
-
-The downloads.json schema version 2 resolves each row with row.media_revision when supplied, otherwise the top-level historical media_revision. Top-level selection_projection_sha256 and source_photo_revision retain their historical 431-row scope, prior to the July 25 correction. The current registry population is the pinned base plus the separate checksum-bound creator correction, identified by registry_base_revision and registry_correction_confirmation. The five additions use the separate exact-hash owner receipt linked above. CSV download URLs are complete per-row resolutions.
-
-## Representation and evidence
-
-The new images preserve their source JPEG codestreams, scan data and Display P3 color profiles without resizing, cropping, enhancement or RAW development. DNG/MPO containers supply their existing primary rendered JPEG; these downloads do not include RAW samples or auxiliary images. The two earlier supplied JPEGs remain labeled available source resolution, without a claim of original camera resolution. Other limited sources remain explicitly limited.
-
-Original source filenames and SHA-256 identities are retained in SOURCE_BINDINGS.json and the retirement receipt; originals remain unchanged and separately preserved. Public JPEG metadata follows the existing JFIF/ICC/necessary-Orientation allowlist. Download orientation follows the source; separately approved small-display rotations retain their own scope.
-
-The master index joins the exact source photograph and existing work ID. The July 25 creator confirmation explicitly establishes that the master photograph and all four reviewed preview frames represent the same physical drawing. Neither decision establishes a recording endpoint, finish state, time, sequence or process completeness. Historical work correspondence confirmations and separately inferred larger-source connections keep their distinct scopes. The separate 435-row photograph manifest, historical 415-work status table and Work_Images pilot retain their pinned scope and bytes.

+The selected-front registry in this main Hugging Face archive is the common
+source for work-level photograph choices, downloadable JPEG representations and
+bounded browsing images. The root work table, recording-photo projection,
+companion photograph dataset and GitHub browser consume that selection.
+
+Source, download and display hashes have different meanings. Existing native-,
+limited- and supplied-source-resolution classes remain unchanged. A download
+role does not guarantee fine detail, calibrated color or a completed drawing
+state. Download dimensions describe the effective EXIF-oriented image; display
+dimensions describe already-normalized pixels.
+
+The [work-table manifest](../../drawing_photographs.manifest.json) and
+[recording-photo manifest](../../viewer/recording_physical_references.manifest.json)
+provide current coverage and output identities. Every active work is either
+selected or explicitly unselected. Confirmed recording membership does not
+require a photograph: an unselected work retains true null images.
+
+## Preserved evidence
+
+The [five-front owner confirmation](Confirmations/2026-10-25-five-master-fronts.json)
+and [July 25 retirement receipt](Retirements/2026-10-25-july-25-duplicate.json)
+retain their original scope. The two July 25 recordings depict stages of one
+drawing; its surviving work ID is selected once. Superseded identities,
+recordings and earlier selections remain available in immutable history.
+
+The 430 surviving earlier HF displays and five already published browser
+displays are imported byte-for-byte. Consolidation performs no new orientation
+correction, RAW development, cropping or enhancement. Existing source filenames,
+container identities, JPEG codestream/profile observations and access boundaries
+retain their documented scope.
+
+Identity evidence, display-selection authority and derivation evidence remain
+separate. Follow the registry's revision-pinned predecessors for the exact
+photograph. Publishing a private input's hash does not make that input publicly
+inspectable. A selected drawing photograph does not establish each recording's
+endpoint, final physical state, finish time or process completeness.
+
+## Maintenance
+
+Update this authoritative registry, validate it, regenerate all source views,
+and refresh the companion/browser from the accepted immutable source revision.
+Do not edit their photo choices independently. Per-row media revisions remain
+authoritative for downloads. Work_Images primary grants and exact derivatives
+keep their separate authority; registry references must match its active manifest
+and confirmation events exactly.

+# Selected-front registry schema
+
+Schema: photo_selections_v1. The authoritative current selection is
+[selections.json](selections.json). Download indexes, work tables, recording-photo
+tables and browser data are generated access views.
+
+The selected works and explicit unselected_work_ids together cover the active
+work registry, without duplication. Superseded IDs cannot be current selections.
+New confirmed works can remain unselected; neither a work link nor a missing
+photograph justifies inventing an image or repeating an owner confirmation.
+
+| Field | Meaning |
+| --- | --- |
+| work_registry, recording_links | Exact current source paths and hashes used to validate population and confirmed joins. |
+| migration | Exact historical import receipt. Its original population and authority are preserved. |
+| unselected_work_ids | Explicit active works with no selected photograph. |
+| source_photograph_sha256 | Selected source identity, which may identify a DNG/MPO container. |
+| source_reference | Separately supported source URL/resolution, or nulls. A rendered JPEG is not substituted for an unavailable source container. |
+| download | Exact JPEG path/hash/size, effective EXIF-oriented dimensions, resolution class and immutable URL/media revision. |
+| display | Exact bounded JPEG path/hash/size, normalized pixel dimensions and orientation 1. |
+| evidence | Work-specific migration entry and revision-pinned predecessor/confirmation locations, with their limits. |
+| work_image_assets, work_image_authority | Optional references checked against the active Work_Images manifest, current grant/replacement events and confirmation hashes. They do not override the browsing selection. |
+
+Display JPEGs are at most 1024 pixels on the long edge and 512 KiB. EXIF
+Orientation is absent or 1; consumers apply no additional rotation. Downloads and
+displays may differ from the source container. Their hashes are not interchangeable.
+Native dimensions do not establish sharpness, calibrated color or suitability.
+
+The migration receipt binds the 430 surviving HF display selections and five
+already published additional displays. GitHub supplies exact derivative bytes
+for import; source associations and five-front identity authority come from the
+main archive. This adds no new identity or per-image derivation assertion.
+
+## Rebuild
+
+From the source repository root:
+
+    python tools/photo_selections.py --root .
+    python tools/build_photo_selection_views.py --root . --source-revision SOURCE_COMMIT --output /fresh/output
+    python tools/build_photo_selection_views.py --root . --check
+
+When work membership or the active population changes, prepare an explicit
+registry proposal that retains every photograph choice and marks new works
+without photographs unselected:
+
+    python tools/photo_selections.py --root . --sync-work-population /fresh/selections.json
+
+Review and install that proposal with the current source indexes, then regenerate
+the work table, recording-photo tables/CSV, manifests and download indexes together.
+Routine recording refresh consumes the same registry. A photograph-only refresh
+also updates the native Viewer manifest while retaining all four recording
+Parquet payloads. Follow the existing ingest workflow for new video rows.
+
+The complete checksum scope is this directory except SHA256SUMS itself.
+An unchanged JPEG represented locally by a Git LFS pointer retains its ordinary
+object SHA-256, not the pointer-file hash. Root MP4/ZIP and Work_Images scopes
+remain separate. Hash/size checks on a pointer establish metadata identity;
+materialized bytes and hosted delivery are reported separately.
