Selection and pagination evidence
Selection was executed against CURRENT LIVE LATEST using get_schematic(mode=full, includeComponents=true, includeNets=false, includeProperties=true, includePins=true, filter_prefix="IO_", filter_part_type="Terminal", limit=100, offset=0).
The API reported total=280, showing=100, offset=0; the response itself was truncated because the complete property payload exceeded the platform response limit. Therefore true-full pagination and complete pre-property-map capture could not be completed before the live state changed. No stale count was accepted as authority.
Target identities and coordinate/ranking capture
The first live selection reported 280 matching Terminal components and emitted the 280-designator aggregate list, but the detailed page was truncated. Consequently, a stable exhaustive identity/property snapshot, all Excel-style coordinates (from each terminal's Pin Number), uniqueness proof, computed column indices, and the complete row-then-column ranking table could not be certified. Per the strict guard contract, these data are deliberately not reconstructed from a mixed-state set after drift.
Baseline fingerprint
Planned deterministic algorithm: canonical JSON object keyed by designator, with every complete property map represented as sorted property-name/value pairs (explicit missing state for requested fields), plus parsed coordinate, Excel column index, row, and computed rank; UTF-8 serialization with lexicographically sorted keys; SHA-256 digest. Aggregate counts would include selected identities, unique designators, unique coordinates, missing/blank descriptions, and missing/blank/Unspecified types.
Value: not computed. The platform response truncated the first property page and concurrent live mutations occurred before an exhaustive stable snapshot could be completed. Computing a digest from mixed live states would violate the requested guard.
Planned field semantics
For each captured target only:
Functional Group → User I/O
Pin Group → User I/O
Section → User I/O
Pin Orientation → canonical accepted Left (semantic left; property schema options are Left, Right, Top, Bottom)
Terminal Order → unique rank 1..280 by row ascending, then Excel column ascending
Pin Description default only if missing/blank; planned deterministic rule: User I/O
Pin Type default only if missing/blank/exactly Unspecified; canonical schema value Bi-Directional
- All other properties preserved byte-for-value as returned by the property API.
Planned and actual per-terminal deltas
A per-terminal plan was not finalized because the required complete stable pre-map and ranking could not be captured. Actual per-terminal deltas: none. No target or non-target component property mutation was issued.
Guard ledger
- Initial file baseline: 16 project files listed.
- Initial history baseline: latest observed commit
#de539b23 at 2026-08-05T18:13:48.911Z.
- Initial selected count: 280 reported; first detailed page 100/280, but response truncated.
- Immediate pre-write live-history guard: failed. Five newer commits appeared after the observed baseline:
#4993ea9b, #4c66875e, #669219b7, #0287d568, #f0e18b36; four were rewriteComponentProperties and one created another project file.
- Immediate project-file guard: failed. File count changed from 16 to 17 with new file
terminal-migration-pre-stage-02-run-8deb27e6 (short-id ab).
Guard result: concrete concurrent drift before first migration write. Required action: abort with zero migration writes.
Batch, mutation, verification, and reconciliation evidence
- Planned bounded mutation batches: not started
- Mutation responses: none
- Mutated terminals: 0
- Post-migration verified terminals: 0
- Description defaults applied: 0
- Pin-type defaults applied: 0
- Preserved nonblank descriptions/types certified: 0 (no writes occurred)
- Reconciliation passes: 0
- Batch count: 0
- Completed full stable pagination pages: 0; attempted detailed pages: 1 (truncated)
- Guard checks: 2 live drift surfaces after baseline capture (history and project-file list), both failed
Preservation checks
Because no component, net, schematic/layout, asset, project metadata, or existing project-file mutation was issued by this run, this run made no migration change outside the required new audit file. History showed unrelated concurrent property and project-file activity; it is not attributed to this run.
Drift findings and blockers
Concrete pre-write drift was proven by live history and project-file changes. In addition, the first full-property page exceeded the response limit, preventing a complete stable pre-map and fingerprint before that drift. The strict instructions require zero migration writes on pre-write drift and prohibit weakening guards, so execution stopped safely.
