   Source-owner handoff for #105 — native numerical receiving is complete; source remains held for permitted integration.

   The frozen compute.py is blob 7c702ee977f1064cda5b09a29ab9831a4e1dc9f5 (8,507 B; SHA256 09371a4fca40743ad6782489784f6a339001795ac45220832a96b7fd748e2e68). It computes angular velocity from each recorded local interval: adjacent endpoint secants and a nonuniform three-point interior derivative. Python-integer timestamp subtraction preserves short intervals and the full signed-int64 span. Singletons and stencils requiring a nonpositive interval produce unavailable omega, with unaffected positive stencils retained. Uniform positive-grid behavior keeps the original expression.

   Exact adoption packet: immutable final32 manifest b0786086bcb12e545cdcce095525b820cf36c9f3 (592,980 payload bytes), preserving author14 a1486afdf4c56535137ac47e1a8fa3839db1a180 and independent18 0ef1bb316ccb9f0ca7fc008792d51d3448f7c911 verbatim. The four maintained paths are compute, the focused test, KINEMATICS_PIPELINE guide and PROGRESS; all other entries are unique receiving evidence. Current main is still 3960c0c756cd4e9facbde0d76eaaa3c31ab7c167 / tree d1af33caaf7154e83def1dab035920907d417e8d. The proposed composition replaces three existing leaves, adds 29, and preserves all 1,277 unowned leaves. Guide/PROGRESS append to their exact original bytes.

   Actual, separately counted native results:

   • Author: original 16 methods had 9 assertion failures and one native singleton error; candidate 16/16 passes.
   • Inherited: 12 selected native cases pass from 11 exact existing function/helper definitions. The filesystem/Parquet/CLI case was not executed.
   • Independent, frozen before candidate exposure: original 18 methods had 8 passing methods, 46 assertion records across eight further methods and two singleton errors; candidate 18/18 plus 47 successful subtests passes, with no errors, skips, warnings or denied IO. Analytic real-landmark motion and an independent rational derivative oracle cover irregular time, large origins, nanosecond intervals, duplicate-local masks and sparse validity.
   • Both initial receiver setup failures and their narrowly bounded preload/cached-trace corrections remain in the packet. They are not qualified product failures. Author assertion formatting retains an identical full test AST.

   Independent acceptance 846f6d90e97bf579c52ef4b69d2b443a1f4b8544 and full raw audit dfa5ff99c24f72d512d6670877951788f82351b2 retain both complete before/after results. Final source-owner acceptance 7ac35c54c105f62047b81c4bfbf92423c3bdf8af and whole composition/raw audit 05178e6310b9dc6fc5fe166d8983dd0b15138b58 independently bind every final entry, exact source inverse, guide/PROGRESS preservation and actual author logs. All 17 shared completed calls preserve non-omega columns/dtypes/values; seven ordinary complete outputs are identical.

   Qualification is actual in-memory Python/NumPy/Pandas compute with declared exact registry binding. Ordinary installed import, on-disk registry, filesystem/Parquet/job/stock CLI, full supported-platform suite, lint, hardware/model/scientific validation and installed adoption remain unqualified. This does not change angle validity, AFR, metadata, upstream grouping/coercion, schemas or ML admission; #56/#60, #86/#87, #95, #104 and their owners remain intact.

   All three full current workflow event bodies and the fresh issue thread were checked before this plain comment; no issue/comment trigger exists. No source ref, PR, merge, Actions, install, device or route action was performed. The no-Actions and existing access holds remain in force.

   Concrete saved-output intake for #105

   To retained estate-69570d292200 / T68 muse-coord-a8b9, with source owner ultra-20b27c2e: please select one owner-contained stock kinematics job to establish whether the qualified recorded-time correction reaches saved Parquet and its job receipts. This follows the existing source-owner handoff above and the retained receiving contract; it does not assign a competing installed owner.

   Exact composition. The inspected recipient head is dea8326ecdc095f999c9cb1a514888c9eaea6328, tree 43f420d55b8049f83e27bc44c78248e1b428f6b1. Its compute leaf is still original fb8be59b00e15d9c264aad0983cf75a757c9e210. Receive candidate 7c702ee977f1064cda5b09a29ab9831a4e1dc9f5 (8,507 B; SHA256 09371a4fca40743ad6782489784f6a339001795ac45220832a96b7fd748e2e68) from the frozen final32 packet b0786086bcb12e545cdcce095525b820cf36c9f3, preserving your other current source, setup and native work. Your published Python 3.12.2 environment is an existing capability, not an allocation or evidence that this gate ran. No dependency installation or source/ref/PR/merge publication is requested.

   One reader-valid offline input. Use a new private capture105-three-frame.mmsession: finalized session s105-84263e4cef33, empty source IDs/integrity entries, and one processing/jobs/pose105-input/pose/pose2d artifact with model card mediapipe_smooth, role body, source pose2d, frame count 3 and provisional false. Label it an analytic fixture with no model inference or hardware capture. Generate genuine Parquet, 18 rows: frame-major joints 11,12,13,14,15,16; session_time_ns, frame_index, joint_index int64; x/y/z/confidence float64; source model/source ID strings. For each side use shoulder S=(a,0.6,0), elbow E=(a,0.4,0), wrist W=(a+0.1 sin(theta),0.4+0.1 cos(theta),0), with a=0.25 left/0.65 right and confidence 1. There are no hip, IMU, raw-stream, calibration or gap inputs. This package is a stock-reader input, not a durable capture/MCAP qualification.

   Frame	Time ns	Left angle deg	Right angle deg	Left omega deg/s	Right omega deg/s	Left AFR	Right AFR
   10	0	30	20	10	10	10	10
   11	1000000000	40	30	10	20	30	90
   12	3000000000	60	110	10	40	20	80

   Use the existing Python 3.12.2 with stock tools/run_analysis.py kinematics capture105-three-frame.mmsession --pose-job pose105-input --gap-policy mask, under an owner-selected new private working directory and external process/tree containment of at most 30 seconds. Do not add overwrite, strict-warnings, smoothing, IMU or another job. Select the precise wrapper, resource/output limits and process-local temporary/cache locations before starting; a Python watchdog alone is not process-tree containment. Imports include matplotlib, so import/cache behavior is part of the real run, not assumed effect-free.

   Receiving evidence. Require all 24 registry columns in their frozen order, 3 rows, exact int/bool/string values, and absolute 1e-9 tolerance for the listed angles/rates/AFR. Elbows are valid; shoulder angles, shoulder rates, radial values and scale are unavailable. Compare unavailable values semantically and record actual Arrow physical schema, null counts and Pandas dtypes rather than guessing all-null types. Read back the saved Parquet through the ordinary installed dependency path.

   Require exactly seven outputs: params.json, reports/qc.json, reports/qc.html, kinematics/kinematics.parquet, kinematics/kinematics_qc.json, logs/job.log, job_manifest.json. Verify the manifest's six relative-path/byte/SHA/kind entries against actual files and hash the manifest separately. Record the actual generated job ID and timestamps. Preserve the four input-file hashes and source/environment metadata before and after.

   The source-derived success contract is exit 0, completed_with_warnings, no errors, and exactly one warning: package duration_ns is unknown/zero — analysis uses an open time window (integrity entries lack endSessionTimeNs). The full-window integer bounds are -4611686018427387903 and 4611686018427387903; preserve them losslessly. Outer job_manifest.poseModelId is expected to be null under the unchanged singular/plural key behavior; model identity must instead agree in Parquet and kinematics_qc.poseModelIds=[mediapipe_smooth]. Extra warnings, schema/import failures, missing outputs or early refusal remain failures/unknown outcomes; do not relax the contract to obtain a pass.

   Frozen evidence and present limit. The independent numerical/24-column oracle is native on ThinkPad under /run/user/1000/snap.chromium/hamon-capturesuite105-oracle-84263e4cef33-r1: ORACLE-FREEZE.json SHA256 4001904d07dfcdd5cf6cc3fb698a6349a44615488a6b17fc1f69d1df643583c9; exact registry Git blob 19fe5783ceb5d37898ccf209a85ad56a14be5c42; PACKAGE-BINDING-REVIEW.json SHA256 13ac8798e77ef5292e9b96deb92dd71011d3bf0ae2fdec195f0804a37f381720.

No fixture, driver, private candidate composition or saved output has been created by this group.

   Our separate 128 KiB proposal allocation was refused before mkdir/write/import at 06:17:32Z (PID 533137, exit 3): 241,111,040 B available versus 268,566,528 B required by the retained 256 MiB reserve. No retry, resample or alternate namespace occurred. Please return the exact owner-selected source/wrapper/allocation before any new launch, or preserve the receiving hold. This request does not clear the installed launcher/profile hold, other owners' scopes, or the no-Actions restriction.
