+# Evidence statement for Pre-Standard physical references
+
+This table is a public index of positive creator-supplied associations between recordings and physical drawings. Its source recordings resolve at Hub revision `275fef5594ae6302af4f6ee4edaa9d5b6f724e83`. Private review records retain the evidence bindings and underlying creator statements. The private photographs and their identifiers are not included here, so readers cannot independently authenticate the visual match from this release.
+
+The 84 photograph-to-frame rows comprise 82 creator-attested decisions in the private comparison gallery, one earlier checksum-bound pilot, and one later creator-identified drawn-front photograph outside the prepared suggestions. In the pilot, the creator directly answered “they are the same” after a side-by-side comparison at 53.60 seconds. For the later photograph, the creator identified the same physical drawing at the selected 357.60-second frame. Where multiple gallery decisions concern one recording, this table uses one accepted decision.
+
+Eight additional frame-specific rows rest on direct in-hand checks of the physical sheets' drawn fronts. The creator answered yes or same when asked whether each front matched its selected recording frame. For `tla-b614c69d069ceb33`, the creator answered “same” to a direct question about the physical sheet's drawn front and the selected p99 frame at 82.10 seconds. For one frame containing two drawings, the creator specified the larger angular drawing below the small upper-left drawing; for another, the creator identified the angular drawing on the right. Each `review_frame_region` limits the assertion to that drawing and makes no claim about another drawing visible in the frame. The earlier indexed private photographs are not claimed to depict the drawing visible in those frames. For `tla-b614c69d069ceb33`, the earlier photograph's depicted side remains unverified and it does not supply drawn-front visual proof or a finish date. The in-hand observations are not reproducible from this public table. Both frame-specific types refer to sampled encoded-video states, not necessarily final drawing states.
+
+The 36 record-level rows have positive creator-reported recording-to-physical-photo associations without a supported public frame locator: 19 from an earlier owner-confirmed private index, 16 from later creator-supplied physical links, and one with an earlier owner-confirmed association whose later comparison note does not support a frame-specific claim. That record remains absent from the frame-specific classes.
+
+This relationship layer contains 128 linked Pre-Standard recordings: 84 photograph-to-frame links, eight in-hand front-to-frame links, and 36 record-level associations. No recording is omitted for lack of a positive physical link. The table does not assign work IDs, merge drawings across recordings, determine whole-MP4 membership, verify endpoints or final state, or establish finish dates. Assistant visual suggestions and candidate rankings do not count as creator confirmation.
+
+The public validator checks structure and pinned-source consistency. It does not re-perform the private visual or in-hand review. Corrections and later identifications should be appended through a new version of this relationship layer, preserving the earlier version as an archival state.

+# Pre-Standard recording to physical drawing references
+
+## Scope
+
+`record_physical_links.csv` records creator-supplied links between a Pre-Standard recording and a physical drawing. Join `record_id` to `Pre_Standard_Time_Lapses/metadata.csv` at the exact `source_hub_revision`. Each row concerns one recording and a privately retained evidence anchor. It is a positive relationship assertion at the scope stated by `relationship_type`, not a claim about every image or drawing in the recording.
+
+The source photographs, their filenames, paths, and digests are omitted from the public dataset. Private review material retains those bindings and the creator's direct in-hand check where applicable. A public reader can verify the recording ID and revision, but cannot independently repeat the private comparison or in-hand check from this table.
+
+This relationship layer does not alter `Physical_References/endpoint_references.csv` or assign a `work_id`. `Work_Identity` remains the authority for recording-to-work membership. The 128 Pre-Standard records have blank `work_id` values in the pinned source metadata.
+
+## Fields
+
+| Field | Meaning |
+| --- | --- |
+| `record_id` | Existing canonical recording ID; unique in this table. |
+| `source_hub_revision` | Full 40-character Hub commit resolving the recording and its pinned metadata. |
+| `review_frame_seconds` | For either frame-specific row, the selected encoded playback position rounded to two decimal places. Blank for a record-level association. This is an evidence locator, not a finish time or endpoint. |
+| `review_frame_region` | Optional location within the selected frame when more than one drawing is visible. Blank by default and for record-level rows. `lower_angular_hourglass_drawing` identifies the larger angular drawing below the small upper-left drawing in the selected frame for `tla-3071851986af09ee`. `right_angular_drawing` identifies the angular drawing on the right in the selected frame for `tla-9aaeea5ca3fc05c8`. Neither token identifies another drawing visible in its frame. |
+| `relationship_type` | One of the three evidence scopes below. |
+| `owner_confirmation_state` | `owner_confirmed` means the creator supplied a positive identification; it does not mean independent verification. |
+| `evidence_access` | `private_photo_not_bundled` means the supporting photograph is retained privately. `private_in_hand_check_not_reproducible` marks a direct creator check of the physical sheet's drawn front against a selected frame; the private evidence and check cannot be repeated from this release. |
+
+### Relationship scopes
+
+| Value | Supported public claim |
+| --- | --- |
+| `owner_confirmed_same_drawing_visible_at_frame` | The creator identified the drawing visible at the specified recording frame with the same physical drawing shown in a selected private photograph. |
+| `owner_confirmed_same_drawing_visible_at_frame_by_in_hand_check` | The creator inspected the physical sheet's drawn front in hand and identified it as the same drawing visible at the specified recording frame. The earlier indexed private photograph is not itself asserted to show visual correspondence with the frame. |
+| `owner_reported_physical_reference_for_record` | The creator associated a retained photograph of a physical drawing with this recording, but the evidence used for this row does not establish a specific reviewed frame. |
+
+The record-level value includes earlier owner-confirmed photo associations and later creator-supplied record/photo links. A blank `review_frame_seconds` is intentional and must not be filled from a candidate rank or a sampled frame without a separate creator confirmation. The in-hand value uses `private_in_hand_check_not_reproducible`; the other two values use `private_photo_not_bundled`.
+
+An in-hand frame link is supported by the creator's direct comparison of the physical sheet's drawn front with a selected recording frame. An earlier indexed private photograph need not show that front and does not by itself verify the depicted side or a drawing finish date. The in-hand link for `tla-b614c69d069ceb33` uses the selected p99 frame at 82.10 seconds; its `review_frame_region` is blank because only one drawing is visible in that frame.
+
+## Claim limits
+
+None of these values establishes that the whole MP4 concerns one drawing, that the recording is complete or gapless, or that the identified drawing is the final state at the video's endpoint. None establishes a drawing finish date, physical dimensions, sequence boundary, or a `work_id`. The table does not identify a named photograph's front/back role. Nearby filenames, visual ranking, and assistant-only comparison do not create a row. A missing row means no accepted public link in this release; it is not a negative identity finding.
+
+For the frame-specific values, `review_frame_seconds` is encoded playback time. It is not the wall-clock time at which a mark was drawn. Frame positions are rounded for navigation; the checksum-bound private review material retains the exact sampled-frame details. `review_frame_region` narrows a frame-level assertion to one drawing within a frame; it does not establish identity for another drawing visible in that frame, a whole recording, or the final physical state. The controlled tokens `lower_angular_hourglass_drawing` and `right_angular_drawing` are permitted only for `tla-3071851986af09ee` and `tla-9aaeea5ca3fc05c8`, respectively, in this release.
+
+## Validation
+
+From a checkout containing the pinned `Pre_Standard_Time_Lapses/metadata.csv`, run:
+
+```text
+python tools/validate_pre_standard_record_physical_links.py --root .
+```
+
+The validator checks table structure, byte hashes, the pinned metadata join, evidence-scope syntax, and public privacy exclusions. It cannot authenticate the private photographs or repeat the creator's identification.
