From bd4349d52dd42a538b452577066e39c8fe29487a Mon Sep 17 00:00:00 2001 From: joelteply Date: Wed, 8 Apr 2026 12:54:08 -0500 Subject: [PATCH 1/4] types: temporary additive checkpoint so published continuum-ai alloys parse MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Checkpoint commit. NOT the architectural fix. The 3 published continuum-ai/* alloys (qwen3-coder-30b-a3b-compacted-19b-256k, olmoe-1b-7b-compacted-5b, qwen2.5-coder-7b-compacted) now validate against ForgeAlloy.model_validate_json() instead of failing with 5-6 errors each. Done by extending core types with sentinel-ai-specific fields (expert-activation-profile, compensation-lora, keepExpertsPerLayer, priorMetricBaselines, calibrationCorpora, etc) and relaxing several required fields to optional. This is the WRONG layer — these belong in an llm-forge domain extension per FORGE-ALLOY-DOMAIN-EXTENSIBILITY.md, not bolted into the universal core. Sentinel-ai is supposed to be a black-box consumer of the universal contract, not a shape that the core mirrors field-for-field. Committing as a checkpoint so the work isn't lost while the domain-registry refactor (work items 0-5 in the extensibility doc) lands properly. The next commit moves every field added here out of types.py and into a domain extension module, restoring the universal core to its pre-checkpoint shape plus only the 'domains[]' registry hook. --- python/forge_alloy/types.py | 149 ++++++++++++++++++++++++++++++++---- 1 file changed, 134 insertions(+), 15 deletions(-) diff --git a/python/forge_alloy/types.py b/python/forge_alloy/types.py index f0c69b4..98136b4 100644 --- a/python/forge_alloy/types.py +++ b/python/forge_alloy/types.py @@ -35,7 +35,8 @@ class BenchmarkResult(BaseModel): class HardwareProfile(BaseModel): """Verified performance on a specific device — generates model card device grid.""" device: str - format: str + format: Optional[str] = None + vram_gb: Optional[float] = Field(default=None, alias="vramGb") size_gb: Optional[float] = Field(default=None, alias="sizeGb") tokens_per_sec: Optional[float] = Field(default=None, alias="tokensPerSec") memory_usage_gb: Optional[float] = Field(default=None, alias="memoryUsageGb") @@ -96,8 +97,8 @@ class IntegrityAttestation(BaseModel): Self-attested only prevents accidental corruption, NOT adversarial modification.

Adds the domain-extension package that the bd4349d checkpoint commit on this branch SHOULD have built instead of bolting ML-specific fields into the universal core. Per the never-lose-work rule, the bd4349d state is preserved on the wip/types-additive-checkpoint-bd4349d branch and is not destroyed by this commit. Per TDD/TDValidation discipline: test first, then implementation. The contract test is in python/tests/test_domain_extension_layout.py; the existing python/tests/test_regression_published_alloys.py acts as the end-to-end gate that the 17 published continuum-ai/* artifacts still validate cleanly through the post-refactor schema. == What landed python/forge_alloy/domains/ — new package base.py DomainExtension ABC. Each registered extension owns: - id (the string the alloy's domains[] field carries) - stage_types() → dict[str, type] (Pydantic models for stages this domain owns) - root_extensions() → dict[str, type] (Pydantic models for root fields this domain adds) registry.py DomainRegistry — id-string → DomainExtension class lookup. Mirror of scripts/adapters/registry.py and scripts/eval_runners/registry.py in sentinel-ai. Strict exact-match dispatch, idempotent same-class re-registration, raises on different-class against existing id (silent shadowing is the f-word pattern). KeyError on unknown id includes the full registered list and the file/registration recipe to add the missing one. llm_forge.py LlmForgeDomain — registered against id 'llm-forge'. Owns every ML-specific stage type: source-config, prune, train, lora, compact, quant, package, eval, publish, deploy, expert-prune, expert-activation-profile, compensation-lora, context-extend, modality, deliver Owns every ML-specific root extension: calibrationCorpora list[CalibrationCorpusRef] priorMetricBaselines list[PriorMetricBaseline] Today, this module RE-EXPORTS the ML types from forge_alloy.types where they currently live (the bd4349d checkpoint state). Consumers can import from EITHER: from forge_alloy import ExpertPruneStage (legacy public API) from forge_alloy.domains.llm_forge import ExpertPruneStage (new path) Both resolve to the same class object today. The full extraction (moving the actual class definitions out of types.py and into llm_forge.py) is a follow-up refactor commit. The dependency direction is strict and enforced by test_universal_core_does_not_import_llm_forge: extensions → core, never core → extensions. photo_provenance.py PhotoProvenanceDomain — stub. Registered against id 'photo-provenance'. Empty stage_types and root_extensions today. Witness that the registry handles non-ML domains without any change to the universal core. Real schemas land when the first photo-provenance artifact ships (camera enclave → edits → publish chain). ticketing.py TicketingDomain — stub. Registered against id 'ticketing'. Empty schemas today. Witness for the venue-ticket / FedEx-delivery / concert-ticket use case from forge-alloy's APPLICATIONS.md. __init__.py Module-level singleton + register_domain / resolve_domain / registered_domains helpers. Eager imports of llm_forge, photo_provenance, ticketing register all three at package import time. Adding a new domain is exactly one new file + one import + one register() call here. == Schema gaps caught by the regression test (real bugs, fixed inline) The python/tests/test_regression_published_alloys.py end-to-end gate exposed several places where the schema was silently dropping fields that the published continuum-ai/* alloys actually carry. These were real bugs (fields the schema didn't know about, dropped on validation, missing on round-trip) and the fix is to add the missing fields to the schema and to allow extras everywhere artifact-specific extras land: AlloyHardware: + device_targets list[str] alias='deviceTargets' (every published alloy carries this — was being silently dropped) + extra='allow' for any future hardware-tier extras AlloyResults: + forged_params_b float alias='forgedParamsB' (MoE-specific param count for the morning's qwen3-coder-30b-a3b and OLMoE flagships — published values were 19.66 and 5.x) + active_params_b float alias='activeParamsB' (unchanged through expert pruning per § 4.1.3.4) + extra='allow' so artifact-specific result extras (fourRunProgression, lossFunctionAblation on v2-7b-coder-compensated) round-trip cleanly BenchmarkResult: + score, base_score, delta, calibrated, samples_path, base_samples_path, result_hash, base_result_hash, metric — all fields the publish pipeline (alloy_to_card.py) and the Tier 4 reproducibility test (sentinel-ai/tests/reproducibility/test_published_alloys_scoring.py) both consume but the schema was hiding behind a generic 'metrics' open dict. Now they're first-class. All other BaseModel classes: model_config now has extra='allow' so artifact-specific extras (notes, methodology anchor URLs, custom provenance fields) preserve verbatim through the round-trip. The schema's named fields stay the canonical surface that publish_model.py + alloy_to_card.py read; extras are recognized as artifact-specific provenance and don't cause silent data loss. == Test status python/tests/test_domain_extension_layout.py: 17 passed python/tests/test_regression_published_alloys.py: 3 passed (qwen3-coder-30b-a3b, olmoe-1b-7b, qwen2.5-coder-7b) Combined: 20 forge-alloy tests, 0 failures Cross-repo sanity: sentinel-ai's reproducibility + unit-test suite still 60 passed / 2 xfailed after this change (the xfails are the same priorMetricBaselines.samplesHash gap that closes in roadmap step 8). Side fix: python/tests/test_regression_published_alloys.py - sys.path now includes python/ so the script + pytest both find forge_alloy without the caller having to PYTHONPATH-set - expected_alloy_hash_prefix for qwen3-coder-30b-a3b updated from aa61c4bdf463847c → 011970c80c2f3429 to reflect the post-correction state pushed in sentinel-ai commit 1bc32d2 (the canonical-evalplus humaneval_plus correction) - semantic_equivalent treats int/float as numerically equivalent when their values match (Pydantic coerces int → float on Optional[float] fields and the round-trip emits float) - round-trip uses exclude_unset=True (preserves null fields) instead of exclude_none=True (was dropping them) Side fix: .gitignore now excludes __pycache__, *.pyc, *.pyo, .pytest_cache so Python bytecode never sneaks into commits. == Next Roadmap step 6: vision-safety integration (Qwen3VLAdapter consults the existing scripts/vision_safety.py whitelist). Step 7 unifies the modelHash convention across publish_model.py and the backfill tools. Step 8 closes the priorMetricBaselines.samplesHash schema gap and uploads the calibration corpora alongside the model weights. --- .gitignore | 6 + python/forge_alloy/domains/__init__.py | 75 +++++ python/forge_alloy/domains/base.py | 65 +++++ python/forge_alloy/domains/llm_forge.py | 162 +++++++++++ .../forge_alloy/domains/photo_provenance.py | 63 +++++ python/forge_alloy/domains/registry.py | 63 +++++ python/forge_alloy/domains/ticketing.py | 50 ++++ python/forge_alloy/types.py | 100 +++++-- python/tests/test_domain_extension_layout.py | 262 +++++++++++++++++ .../tests/test_regression_published_alloys.py | 264 ++++++++++++++++++ 10 files changed, 1083 insertions(+), 27 deletions(-) create mode 100644 python/forge_alloy/domains/__init__.py create mode 100644 python/forge_alloy/domains/base.py create mode 100644 python/forge_alloy/domains/llm_forge.py create mode 100644 python/forge_alloy/domains/photo_provenance.py create mode 100644 python/forge_alloy/domains/registry.py create mode 100644 python/forge_alloy/domains/ticketing.py create mode 100644 python/tests/test_domain_extension_layout.py create mode 100644 python/tests/test_regression_published_alloys.py diff --git a/.gitignore b/.gitignore index 44470e3..59d4d2c 100644 --- a/.gitignore +++ b/.gitignore @@ -1 +1,7 @@ /rust/target/ + +# Python build / bytecode +__pycache__/ +*.pyc +*.pyo +.pytest_cache/ diff --git a/python/forge_alloy/domains/__init__.py b/python/forge_alloy/domains/__init__.py new file mode 100644 index 0000000..1f0b9b0 --- /dev/null +++ b/python/forge_alloy/domains/__init__.py @@ -0,0 +1,75 @@ +"""forge_alloy.domains — registered vocabularies for the universal core. + +Each domain extension is a registered vocabulary for one universe of +data transformation pipelines.

Each family adapter knows what corpus/step-count/LR works best for its architecture and model size.
