DFX7xxx — Provenance, drift and lint

9 codes in this family (4 error, 5 warning). The message is the format string as the compiler holds it: %s, %d and %c are substituted at runtime.

DFX7001

Cause. The asset carries no provenance stamp: it was never generated from this source, or it was built by hand.

Fix. Run the build. If the asset is hand-built and should stay that way, do not point a .dfs at its path -- a build would overwrite it.

DFX7002

Cause. The asset was generated from a different revision of this source. This is the case nobody notices on their own: someone edited a .dfs, did not rebuild, and committed both. A build alone would pass, because a build fixes it.

Fix. Run the DreamFX build and commit the asset with the source.

DFX7003

Cause. The asset was generated by an older generator. The same text can lower to a different asset after a generator change, so the stamp records the version.

Fix. Rebuild.

DFX7004

Cause. -Verify found no asset at all for this source.

Fix. Run the build.

DFX7005

Cause. R7 drift. The source did not change and the asset did not change, but a module they both depend on now exposes a different version -- so the asset was built against a different module than the one this build would use. Nothing in the source or the asset says anything about it, which is why the stamp records module versions.

Fix. Rebuild to adopt the new version, or pin the module with @<version> to have the mismatch reported at the call site. A warning by default because an engine upgrade hits every source at once and a rebuild resolves it; -StrictVersions makes it an error, for a release gate.

DFX7101

Cause. A GPU emitter cannot read its own particle positions back to compute bounds, so without a fixed box it gets a default one and vanishes the moment the camera looks at it from the wrong angle.

Fix. Set FixedBounds = box(...) on the emitter or the system.

DFX7102

Cause. Rate-based spawning has no ceiling of its own: a long-lived emitter with an automatic allocation estimate keeps reallocating, and a runaway rate has nothing to stop it.

Fix. Set AllocationMode = Fixed; and PreAllocationCount to cap the particle count.

DFX7103

Cause. Randomness without a fixed seed means the effect differs every play. Fine for ambience, wrong for anything a cinematic or a test compares against.

Fix. Add Determinism = true; and a RandomSeed if reproducibility matters.

DFX7104

Cause. The renderer has no material and DreamFX knows no engine default for its type, so it draws nothing at all.

Fix. Set Material = "...";
