From 2835e7ca12209fe20d9cfe2936d49621d8c40ec7 Mon Sep 17 00:00:00 2001 From: Kadir Eren Altintas Date: Fri, 25 Sep 2026 00:02:37 +0300 Subject: [PATCH 1/6] M4: deterministic risk tiers, zero-call and single-pass review, per-tier budgets Add a PR-level change/risk classifier (patchfrog.change_risk) that sorts a diff into no_ai/tiny/normal/elevated/high_risk from deterministic signals only (docs/comment/generated/lockfile-only, size, cross-module, manifests, CI, public interface, schema, migrations, security-sensitive paths, static findings). Comment detection is conservative and verified exactly with the Python tokenizer when file content is available. With the cost-aware strategy (operator default via PATCHFROG_REVIEW_STRATEGY): - no_ai runs make zero provider calls but are still persisted SUCCEEDED with a reason, and the check run explains the deterministic result; - tiny/normal/elevated/high-risk runs make one single-pass UNIFIED call per candidate batch with shared, de-duplicated context, then escalate sequentially to a Security/Correctness specialist only with a typed reason; the unchanged validation/critic/confidence pipeline decides what survives; - per-tier provider-call ceilings sit on the existing ReviewBudget ledger, with a verification reserve so review work can never starve a mandatory critic call (tiny = one reviewer call plus a critic-only reserve); - tiny/normal runs narrow context and never expand adaptively; - the cost policy fingerprint joins run identity, and --force / force_review bypasses exact-head reuse. Risk tier, signals, escalation reasons, context cost and budget status are persisted (migration 0033), exported in telemetry (schema v12), exposed as Prometheus counters, and summarized by ReviewRunSummary.cost_report(). The pre-M4 specialist fan-out is kept as ReviewStrategy.SPECIALIST_FANOUT and remains the service's behavior when no cost policy is passed. --- apps/worker/tasks/publish_review.py | 9 +- apps/worker/tasks/review_pull_request.py | 8 + .../versions/0033_review_cost_engine.py | 52 ++ patchfrog/change_risk/__init__.py | 37 + patchfrog/change_risk/classifier.py | 334 +++++++ patchfrog/change_risk/comments.py | 168 ++++ patchfrog/change_risk/domain.py | 175 ++++ patchfrog/change_risk/paths.py | 181 ++++ patchfrog/config/settings.py | 34 + patchfrog/indexing/inventory.py | 8 + patchfrog/ops/metrics.py | 9 + patchfrog/persistence/models/review.py | 15 + .../persistence/repositories/review_run.py | 13 + patchfrog/publishing/checks.py | 18 + patchfrog/review/agents/evidence.py | 22 + patchfrog/review/agents/roles.py | 7 + patchfrog/review/budget.py | 26 +- patchfrog/review/config.py | 24 +- patchfrog/review/cost_policy.py | 228 +++++ patchfrog/review/critic.py | 1 + patchfrog/review/domain.py | 58 ++ patchfrog/review/orchestration.py | 212 ++++- patchfrog/review/prompt.py | 90 ++ patchfrog/review/service.py | 875 +++++++++++++++--- patchfrog/review/single_pass.py | 250 +++++ patchfrog/telemetry/collector.py | 29 + patchfrog/telemetry/domain.py | 36 +- tests/integration/test_review_cost_engine.py | 401 ++++++++ tests/unit/test_change_risk_classifier.py | 267 ++++++ tests/unit/test_m4_cost_engine_versioning.py | 43 + .../test_production_execution_versioning.py | 7 +- tests/unit/test_review_cost_policy.py | 98 ++ tests/unit/test_review_single_pass.py | 154 +++ .../latest-summary.md | 161 ++++ 34 files changed, 3927 insertions(+), 123 deletions(-) create mode 100644 migrations/versions/0033_review_cost_engine.py create mode 100644 patchfrog/change_risk/__init__.py create mode 100644 patchfrog/change_risk/classifier.py create mode 100644 patchfrog/change_risk/comments.py create mode 100644 patchfrog/change_risk/domain.py create mode 100644 patchfrog/change_risk/paths.py create mode 100644 patchfrog/review/cost_policy.py create mode 100644 patchfrog/review/single_pass.py create mode 100644 tests/integration/test_review_cost_engine.py create mode 100644 tests/unit/test_change_risk_classifier.py create mode 100644 tests/unit/test_m4_cost_engine_versioning.py create mode 100644 tests/unit/test_review_cost_policy.py create mode 100644 tests/unit/test_review_single_pass.py create mode 100644 validation/m4_m5_cost_engine_dependency_discovery/latest-summary.md diff --git a/apps/worker/tasks/publish_review.py b/apps/worker/tasks/publish_review.py index 0e63ad2..6cdd1c9 100644 --- a/apps/worker/tasks/publish_review.py +++ b/apps/worker/tasks/publish_review.py @@ -50,6 +50,7 @@ ReviewCheckState, ReviewCheckUpdate, github_check_publisher, + no_ai_check_detail, ) from patchfrog.publishing.config_resolution import resolve_repository_publication_config from patchfrog.publishing.domain import ( @@ -165,7 +166,13 @@ async def _publish_review( update=ReviewCheckUpdate( state=check_state, accepted_findings=len(findings), -

Committed result: evaluation_baselines/m4_cost_benchmark.{json,md} -- 23 -> 10 provider calls, every target met, no finding lost. It measures call shape and cost, never model quality. - The evaluation runner evaluates the production cost-aware path by default; `eval run --review-strategy specialist_fanout` keeps the pre-M4 arm. EvaluationIdentity records the strategy. The oracle answers for every target in a multi-target prompt. Tests that exercise per-role provenance now request the specialist strategy explicitly. - CLI review wires the operator cost policy, adds --force, and prints a cost line; --dry-run prints the risk tier and reasons. - docs/cost-aware-review.md documents tiers, budgets, the verification reserve, escalation reasons and observability. --- docs/cost-aware-review.md | 164 +++++++ evaluation_baselines/m4_cost_benchmark.json | 427 ++++++++++++++++++ evaluation_baselines/m4_cost_benchmark.md | 19 + patchfrog/cli.py | 92 +++- patchfrog/evaluation/cost_benchmark.py | 420 +++++++++++++++++ patchfrog/evaluation/domain.py | 5 + patchfrog/evaluation/oracle.py | 18 +- patchfrog/evaluation/runner.py | 23 +- pyproject.toml | 6 +- .../cost_benchmark/base_repo/README.md | 3 + .../cost_benchmark/base_repo/app/__init__.py | 0 .../base_repo/app/api/__init__.py | 0 .../base_repo/app/api/handlers.py | 15 + .../base_repo/app/auth/__init__.py | 0 .../base_repo/app/auth/session.py | 14 + .../base_repo/app/billing/__init__.py | 0 .../base_repo/app/billing/calc.py | 14 + .../base_repo/app/billing/invoice.py | 23 + .../cost_benchmark/base_repo/app/models.py | 16 + .../base_repo/app/notifications/__init__.py | 0 .../base_repo/app/notifications/email.py | 11 + .../migrations/versions/0001_initial.py | 11 + .../base_repo/tests/test_calc.py | 9 + tests/fixtures/cost_benchmark/scenarios.yaml | 153 +++++++ tests/integration/test_cost_benchmark.py | 62 +++ .../test_evaluation_runner_end_to_end.py | 36 +- 26 files changed, 1517 insertions(+), 24 deletions(-) create mode 100644 docs/cost-aware-review.md create mode 100644 evaluation_baselines/m4_cost_benchmark.json create mode 100644 evaluation_baselines/m4_cost_benchmark.md create mode 100644 patchfrog/evaluation/cost_benchmark.py create mode 100644 tests/fixtures/cost_benchmark/base_repo/README.md create mode 100644 tests/fixtures/cost_benchmark/base_repo/app/__init__.py create mode 100644 tests/fixtures/cost_benchmark/base_repo/app/api/__init__.py create mode 100644 tests/fixtures/cost_benchmark/base_repo/app/api/handlers.py create mode 100644 tests/fixtures/cost_benchmark/base_repo/app/auth/__init__.py create mode 100644 tests/fixtures/cost_benchmark/base_repo/app/auth/session.py create mode 100644 tests/fixtures/cost_benchmark/base_repo/app/billing/__init__.py create mode 100644 tests/fixtures/cost_benchmark/base_repo/app/billing/calc.py create mode 100644 tests/fixtures/cost_benchmark/base_repo/app/billing/invoice.py create mode 100644 tests/fixtures/cost_benchmark/base_repo/app/models.py create mode 100644 tests/fixtures/cost_benchmark/base_repo/app/notifications/__init__.py create mode 100644 tests/fixtures/cost_benchmark/base_repo/app/notifications/email.py create mode 100644 tests/fixtures/cost_benchmark/base_repo/migrations/versions/0001_initial.py create mode 100644 tests/fixtures/cost_benchmark/base_repo/tests/test_calc.py create mode 100644 tests/fixtures/cost_benchmark/scenarios.yaml create mode 100644 tests/integration/test_cost_benchmark.py diff --git a/docs/cost-aware-review.md b/docs/cost-aware-review.md new file mode 100644 index 0000000..41442fb --- /dev/null +++ b/docs/cost-aware-review.md @@ -0,0 +1,164 @@ +# Cost-Aware Review (M4 — Ultra-Low-Cost Review Engine) + +PatchFrog's product direction is dependency/API compatibility +(see `docs/architecture.md`).

Provider-agnostic domain: ExternalDependency, DependencyProvider, DependencyVersion (declared/resolved), DependencyUsageSite (file, line, enclosing symbol from the index's own parser), DiscoveryEvidence, DependencyContract/ContractSource/ContractFingerprint, confidence. - DependencyProviderAdapter interface; OpenAI, Stripe and GitHub are declarative ProviderSpecs of one adapter (a new provider is one spec), plus a generic OpenAPI adapter and generic declared packages. - OpenAPI 3.x/Swagger 2.0 normalization (paths, methods, parameters, bodies, responses, security, components) with fingerprints that ignore format/order/prose but change on real path/schema/auth changes. - Secret-value discipline: secret-store-like files are never opened, only tracked files are read in a git checkout, env values and literal defaults are never captured, URLs keep host + sanitized path only, and URL-shaped version specs are reduced to url:. - Dependency graph on the existing GraphNode/RepositoryEdge primitives, and text/JSON inventory reports. - Fixture repositories (mixed multi-provider demo, false-positive traps) and tests for versions, scanners, no-secret handling, fingerprints and provider extensibility. --- patchfrog/dependencies/__init__.py | 17 + patchfrog/dependencies/adapters.py | 352 ++++++++++++++ patchfrog/dependencies/discovery.py | 334 ++++++++++++++ patchfrog/dependencies/domain.py | 265 +++++++++++ patchfrog/dependencies/files.py | 117 +++++ patchfrog/dependencies/graph.py | 82 ++++ patchfrog/dependencies/manifests.py | 257 +++++++++++ patchfrog/dependencies/openapi.py | 273 +++++++++++ patchfrog/dependencies/openapi_adapter.py | 179 ++++++++ patchfrog/dependencies/report.py | 146 ++++++ patchfrog/dependencies/scan.py | 428 ++++++++++++++++++ patchfrog/intelligence/graph.py | 12 + .../false_positive_repo/README.md | 1 + .../false_positive_repo/ci_helpers.py | 5 + .../false_positive_repo/github.py | 5 + .../dependencies/false_positive_repo/main.py | 13 + .../dependencies/false_positive_repo/web.js | 7 + .../dependencies/mixed_repo/app/__init__.py | 0 .../mixed_repo/app/ai/__init__.py | 0 .../dependencies/mixed_repo/app/ai/chat.py | 18 + .../mixed_repo/billing/checkout.js | 16 + .../mixed_repo/config/__init__.py | 0 .../mixed_repo/config/settings.py | 7 + .../mixed_repo/integrations/__init__.py | 0 .../mixed_repo/integrations/github.py | 15 + .../dependencies/mixed_repo/openapi.yaml | 64 +++ .../dependencies/mixed_repo/package-lock.json | 9 + .../dependencies/mixed_repo/package.json | 7 + .../dependencies/mixed_repo/requirements.txt | 2 + .../mixed_repo/services/__init__.py | 0 .../mixed_repo/services/inventory.py | 16 + .../mixed_repo/workers/__init__.py | 0 .../mixed_repo/workers/summarize.py | 9 + .../integration/test_dependency_discovery.py | 164 +++++++ .../test_dependency_manifests_and_scan.py | 158 +++++++ .../unit/test_openapi_contract_fingerprint.py | 142 ++++++ 36 files changed, 3120 insertions(+) create mode 100644 patchfrog/dependencies/__init__.py create mode 100644 patchfrog/dependencies/adapters.py create mode 100644 patchfrog/dependencies/discovery.py create mode 100644 patchfrog/dependencies/domain.py create mode 100644 patchfrog/dependencies/files.py create mode 100644 patchfrog/dependencies/graph.py create mode 100644 patchfrog/dependencies/manifests.py create mode 100644 patchfrog/dependencies/openapi.py create mode 100644 patchfrog/dependencies/openapi_adapter.py create mode 100644 patchfrog/dependencies/report.py create mode 100644 patchfrog/dependencies/scan.py create mode 100644 tests/fixtures/dependencies/false_positive_repo/README.md create mode 100644 tests/fixtures/dependencies/false_positive_repo/ci_helpers.py create mode 100644 tests/fixtures/dependencies/false_positive_repo/github.py create mode 100644 tests/fixtures/dependencies/false_positive_repo/main.py create mode 100644 tests/fixtures/dependencies/false_positive_repo/web.js create mode 100644 tests/fixtures/dependencies/mixed_repo/app/__init__.py create mode 100644 tests/fixtures/dependencies/mixed_repo/app/ai/__init__.py create mode 100644 tests/fixtures/dependencies/mixed_repo/app/ai/chat.py create mode 100644 tests/fixtures/dependencies/mixed_repo/billing/checkout.js create mode 100644 tests/fixtures/dependencies/mixed_repo/config/__init__.py create mode 100644 tests/fixtures/dependencies/mixed_repo/config/settings.py create mode 100644 tests/fixtures/dependencies/mixed_repo/integrations/__init__.py create mode 100644 tests/fixtures/dependencies/mixed_repo/integrations/github.py create mode 100644 tests/fixtures/dependencies/mixed_repo/openapi.yaml create mode 100644 tests/fixtures/dependencies/mixed_repo/package-lock.json create mode 100644 tests/fixtures/dependencies/mixed_repo/package.json create mode 100644 tests/fixtures/dependencies/mixed_repo/requirements.txt create mode 100644 tests/fixtures/dependencies/mixed_repo/services/__init__.py create mode 100644 tests/fixtures/dependencies/mixed_repo/services/inventory.py create mode 100644 tests/fixtures/dependencies/mixed_repo/workers/__init__.py create mode 100644 tests/fixtures/dependencies/mixed_repo/workers/summarize.py create mode 100644 tests/integration/test_dependency_discovery.py create mode 100644 tests/unit/test_dependency_manifests_and_scan.py create mode 100644 tests/unit/test_openapi_contract_fingerprint.py diff --git a/patchfrog/dependencies/__init__.py b/patchfrog/dependencies/__init__.py new file mode 100644 index 0000000..219e979 --- /dev/null +++ b/patchfrog/dependencies/__init__.py @@ -0,0 +1,17 @@ +"""External dependency discovery + contract registry (M5). + +Given a repository, identify which external APIs/SDKs it depends on -- +with package/version evidence, usage sites and normalized contract +fingerprints -- from static repository evidence only, never reading a +secret value.

Mon Sep 17 00:00:00 2001 From: Kadir Eren Altintas Date: Fri, 25 Sep 2026 00:11:00 +0300 Subject: [PATCH 4/6] M5: persistent contract registry, dependencies CLI and architecture docs - external_dependencies / external_dependency_usage_sites / external_contract_snapshots (migration 0034, all cascading from repositories): latest state per dependency, current usage sites, and a contract history with one row per distinct fingerprint. - DependencyRegistry.record_inventory is idempotent (identical re-discovery writes no rows), updates versions/contracts in place while adding a new snapshot, marks vanished dependencies removed and reactivates them, rewrites usage sites only when they change, and serializes per-repository writes with an advisory lock. - `python -m patchfrog.cli dependencies discover [--json] [--persist --full-name owner/repo] [--all] [--output]`. - docs/architecture.md: the new product architecture (discovery -> registry -> [M6] upstream change detection -> impact -> migration -> verification -> PR), with generic review marked secondary and M6+ marked future. docs/dependency-discovery.md, roadmap and cost-guard cross-links updated. ---

Beyond the stricter result typing (fixed in the previous commit), 2.1 moved aiosqlite onto the generic asyncio cursor adapter, which keeps cursors open until soft-close. Under the shared-connection StaticPool SQLite test fixture, concurrent review sessions then hit "cannot commit transaction - SQL statements in progress" (4 integration tests). Production (asyncpg, real pool) is unaffected, but a runtime-behavior minor bump must be an explicit change, not resolver drift. --- pyproject.toml | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) diff --git a/pyproject.toml b/pyproject.toml index ed123ea..abc5e81 100644 --- a/pyproject.toml +++ b/pyproject.toml @@ -9,7 +9,11 @@ dependencies = [ "uvicorn[standard]>=0.32,<1.0", "pydantic>=2.9,<3.0", "pydantic-settings>=2.6,<3.0", - "sqlalchemy[asyncio]>=2.0,<3.0", + # Capped below 2.1: 2.1 reworked the aiosqlite cursor lifecycle, which + # breaks the shared-connection (StaticPool) SQLite test fixture under + # concurrent sessions.
