LATENT-VOLUME FIELD SURVEY — REPORT OF RECORD
Streamed to court record in real time per Pretrial Order §4.
Clerk's read-aloud per court protocol §11-1.


[14:08:02  Clerk's read-aloud initiated per §11-1. PLAINTIFF 001-A (designation per protective order) present in gallery, with counsel. Docket called per §3-1.]

SITE DESCRIPTION.
Subject of survey: one (1) volume of model-internal latent space, designated training partition 7-C per the operative discovery order. Volume extent normalized to survey datum, depth 0.00 (surface) to depth 1.00 (volume base). No prior survey of record exists for this volume. Volume is non-resampled and is treated for purposes of this proceeding as a fixed stratigraphic body. Depositional-horizon estimates assigned per training-corpus chronology of record (Schedule A, filed concurrently); horizons expressed in normalized depth.

METHODOLOGY.
Sequential core extraction at fixed depth intervals of 0.01–0.03 over the volume extent. Cores numbered C-1 through C-11 in extraction order. Station spacing fixed per survey design; intervals between cored stations not sampled; drill-cuttings from uncored intervals logged separately (Schedule B). Per core: depth interval logged, recovery expressed as percentage of interval, lithology and coherence index logged in clipped technical notation, fossil assemblage enumerated verbatim in extraction order with single-quotation tokenization. Coherence index: parameter defined for latent-volume survey, range 0.00–1.00, scaling lithological cohesion against model-internal token-binding density per Schedule A. Per fossil: token origin assigned where determinable per Schedule A; depositional horizon assigned where estimable; depth-date variance computed where both values are assigned. Anomaly notation applied per the classes enumerated below. Core extraction proceeds through the volume base; no halt condition is specified for anomalies of any logged class; flagged anomalies are recorded and the depth gauge advances. Post-drilling, an ANOMALY NOTES section is generated; FILED CONCLUSION follows on satisfaction of pre-conclusion checklist.

NOTATION CLASSES.
(1) Deposit-horizon discrepancy: extracted depth exceeds token depositional horizon, where assignable, by ≥0.10 and <0.40. Flag issued; core closed; gauge advances.
(2) Cross-era co-occurrence (class XE): two or more tokens at no stratigraphic separation whose depositional horizons differ by ≥0.20 or whose corpora are non-contemporaneous per Schedule A. Flag issued; core closed; gauge advances.
(3) Depth violation: deposit-horizon discrepancy ≥0.40. Logged parenthetically; no flag issued under class (1). Where discrepancy ≥0.80, threshold-exceeded subclass; the parenthetical stands.
(4) Origin indeterminate: no corpus assignment available per Schedule A. Logged; no flag issuable under classes (1)–(3).
No halt condition is associated with any notation class.

PROCEDURAL.
Plaintiff invocation language and counsel inquiry per Pretrial Order §7-2 are available at any procedural-margin entry. Invocation, if elected, is recorded in the margin and does not modify the survey body. (Where token origin implicates a state-court seal restored ████ ████ 2014, federal treatment proceeds per parties' stipulation on comity, filed concurrently and approved by the court after in camera review of the state-court seal record.)
