Typed contract
The frozen A04 API exposes inspect, import, mutate, export, and verify for editable PPTX templates, stable source-bound slide/object locators, designated text/brand slots, safe opaque preservation, and explicit v1 exclusions.

Gate record
What each gate checked, in the verifier’s words.
These summaries were written when the gate closed and are stored with the release. They are not marketing copy and they are not regenerated.
Fixtures red before implementation
Sixteen fixture classes cover minimal, corporate, 55-slide, unrelated, structural boundary, hostile, known-bad, determinism, round-trip, and composition behavior. The pre-implementation suite exited 1 because the module did not exist; the implemented dangling-relationship gate returns FAIL while ZIP integrity alone passes.
PASSFocused correctness
W03 independently reproduced 84 focused template/archive/editability/structural tests, typecheck, build, lint (zero errors; five pre-existing warnings), and the clean packaging gate. From an offline frozen-lockfile install with packages/protocol/dist absent, the core build rebuilt @runstamp/protocol and pack:check passed; its packed public declarations contain no forbidden private @runstamp/protocol import.
PASSSemantic safety
The API preserves rich existing corporate fixtures with multiple themes/masters/layouts, charts, tables, media, notes, comments, relationships, and opaque parts; rejects encryption, macros, OLE, malformed XML, unsafe paths, dangling relationships, budget overruns, unknown slots, and cancellation; and never fetches external targets.
PASSDeterminism and declared loss
Two clean processes emitted byte-identical 55-slide source and mutated outputs. Output SHA-256 is b15a2e6f7c2f7679cdf1a4a4336c22c25485601deb2b4e650dd8b3e36988758d; animation, external-target, and unsupported-slot limits are stable PPTX_* losses.
PASSReference application validation
PowerPoint 16.111.3 opened and rendered all 55 slides without a repair dialog, exported a 55-page PDF, and saved a PPTX copy that retained 55 objects/slots and passed 833 structural checks. LibreOffice 26.2.2.2 exported 55-page source/output PDFs and a re-exported PPTX that passed verification. PowerPoint visual MAE was 0.00232203 on the declared changed slide and 0 on the unchanged slide, below 0.025/0.005 thresholds.
PASSIndependent reproduction
W03 independently used an offline frozen-lockfile install and reproduced the fresh clean-build pack:check gate, focused hostile/known-bad semantic rejection, two-process byte determinism, 55-slide/55-object/55-slot verification, artifact hashes, and 55-page PowerPoint/LibreOffice reference PDF checks. The known-bad ZIP passes CRC but verifyPptxTemplate returns FAIL with PPTX_RELATIONSHIP_TARGET_MISSING; all required gates pass.
PASSTyped invocation
One operation contract across API, SDK and MCP.
Every registered operation is reachable at the same URL shape, with the same envelope: the value, the loss ledger, the diagnostics and the provenance receipt.
