AI can generate an SPFx project. That is not the same as proving the project is ready.

The latest `spfx-factory`

release adds an evidence ledger around the existing generation workflow:

`SCAFFOLD`

— whether the official scaffold completed;`CODEX`

— whether implementation was requested and completed;`POLICY`

— whether static policy checks passed;`LOCAL`

— whether requested local npm checks passed;`ASSURANCE`

— whether an independent `spfx-assurance`

check ran;`TENANT`

— always explicitly `not-tested`

.Every check reports one of:

`verified`

;`warning`

;`blocked`

;`not-tested`

.The existing factory report status remains backward compatible. Evidence is recorded in a parallel `evidence`

field rather than silently changing the old contract.

The factory can invoke `spfx-assurance`

when it is already available through `SPFX_ASSURANCE_BIN`

or `PATH`

.

It does not:

`npx`

;When the checker is absent, the result is `not-tested`

with an actionable explanation.

```
spfx-factory inspect --output ./generated
spfx-factory inspect --output ./generated --json
```

The inspection command is read-only. It reads the existing `factory-report.json`

, prints the evidence, and does not rerun generation or verification.

Warnings do not break an otherwise green run by default. Teams that want warning-gating can opt in:

```
spfx-factory generate \
  --spec specs/document-review.json \
  --output ./generated \
  --fail-on warning
```

This is local evidence, not tenant validation. A green local report does not prove:

That limitation is part of the report, not a footnote hidden outside it.

The useful product boundary for AI-assisted SPFx development is not “the model wrote code.” It is:

The system cannot call the work complete without showing what was checked, what passed, and what remains unknown.

The project is open source:

The release adds an evidence layer to the factory while preserving its existing generation and policy behaviour.
