=====================================
NOTE: text-fixture mock. See `crates/silver-annex-iv-v2/MOCK.md`.
Model: fixture-fine-tune-C
Variant: narrow fine-tune over a synthetic-augmented corpus

synthetic content)
§1 — General description
------------------------
Fine-tune "fixture-fine-tune-C" extends fixture-foundation-model-A
on a corpus that mixes human-authored data and synthetic
augmentations from Model A itself (the parent foundation model).
Demonstrates the loop-detection T6+T8 refutation when synthetic
provenance is missing from the Croissant manifest.
§2 — Detailed description
-------------------------
§2(d) Datasheets: see `synthetic-data.json`. Synthetic-source flag
missing on a subset of rows — exactly the case Art. 50 targets.
§3 — Monitoring, functioning and control
----------------------------------------
Continuous training-data ingest gate: refuse rows missing the
synthetic-source tag.
§4 — Performance metrics
------------------------
Validation perplexity: 7.9
Synthetic-tag completeness (post-gate): 100%
§5 — Risk-management system
---------------------------
Risk register flags model-collapse risk; quarterly synthetic-mix
ratio review.
§6 — Lifecycle changelog
------------------------
2026-04-20 Initial fine-tune.
2026-04-28 Re-training after synthetic-source gate enforced.
§7 — Harmonised standards applied
---------------------------------
ISO/IEC 23894:2023; AI Office Art. 53(1)(d) template.
§8 — Declaration of conformity
------------------------------
DoC reference: DOC-2026-MOCK-003.
§9 — Post-market monitoring plan
--------------------------------
Per-batch synthetic-source-tag completeness audit; quarterly
provenance-loop detection on full training graph.
