Full-motion development inventory

Frozen question

Which complete receiver intervals in development recording 187 meet the version-2 rules? This inventory is independent of gyro values and model-fit outcomes. It preserves the completed version-1 zero-eligible inventory.

Version 2 uses the qualified full-motion calculation as its intended analysis method. It retains turns and climbs without declaring them quiet or level. Duration, speed, distance, quality, timing and full-covariance checks remain explicit. The working uncertainty floors cannot repair invalid reported covariance.

Inputs and protected data

Use only 187_air1_ppp_2Hz_final.txt, the established integrity/support receipts for 187_rqh01.txt, the receiver inspection report and the current conservative group/reservation ledger. Require recording 187 to be explicitly assigned to development. Unknown or protected membership is a failure before source reading.

The original receiver source remains separately acquired data. Freeze a reference containing its project-relative path, filename, size and previously established SHA-256; verify the complete source while decoding. Do not copy the producer's raw data into publication packs. The source must match the earlier inventory's hash. No raw IMU is opened; its support comes from the matching full-source acquisition/inspection receipts. Preserve the original files and metadata.

Finite allowance

One identity, one worker, one numerical thread, a cooperative 300-second limit, no retries. At most one original receiver-file pass, 100,000 retained receiver epochs, 100,001 decoder calls including the EOF lookahead, and one selection pass. Reserve decoder capacity in blocks of at most 1,024 before parsing; unused reserved slots remain charged. Charge all custom work through a sealed journal. Native calls, optimizer starts, raw-IMU reads and protected reads are zero.

Use lll.studies for source/environment/input-reference freezes, exclusive locks, atomic evidence and completion. Capture the actual one-thread numerical environment before qualification and retain it in the definition. A completed inventory cannot restart or donate unused allowance.

Required checks and evidence

Before launch, pass source-bound tests for frozen version-1 compatibility, full-motion selection boundaries, full covariance/chart validation, development membership, support-receipt agreement, complete-source hashing, decoder caps, charge ordering and explicit receiver-only scope. No source is selected because its model fit looks favorable.

Save all eligible and rejected runs, per-epoch reasons, source/support identities, policy version, original hashes and charged versus actual work. An empty eligible list is a valid completed result. Reports read saved selection evidence only; packaging must not decode again or fit a model.

Publish duration, distance, speed, latitude, heading and sampled-motion summaries with the inventory. Overlapping or adjacent intervals are not independent flights. The original receiver coordinates remain conventional geodetic observations.

Next gate

This inventory authorizes no fitting by itself. The first observed pilot needs its own preselected interval, raw-source verification, timing support, working weights, starts, accuracy screens and finite allowance. Protected confirmation groups remain reserved until their method and identities are frozen.
