Summary

  • 14 entity contracts scoring repository artifacts 0-100 with letter grades
  • 155 elements across 4 tiers (identity, proof, orientation, ecosystem)
  • 4 profiles: any, cli-tool, library, ml-framework (inheriting)
  • Calibrated against polars to prevent false failures
  • All 14 contracts at 100/100 Grade A on ml-framework profile
  • Book chapter (ch14b) documenting the system

Repo-Level Contracts (9, 105 elements)

  • readme, repo, crate, ci, changelog, dep, spec, api, error

Domain-Specific Contracts (5, 50 elements)

  • subcommand (56/56 commands pass), model, template, binary, server

Additional

  • apr code spec with 6 equations, 10 entity elements, dogfooded with Qwen3 1.7B
  • apr completions bash|zsh|fish + apr man (hidden subcommands)
  • apr explain exit code fix (exit 3 on missing file, was exit 0)
  • GrepTool schema fix (says "substring" not "regex")
  • SECURITY.md, .gitattributes, lint inheritance on all 73 crates
  • CI hardening: SHA pins (33 actions), permissions, timeouts on all 7 workflows
  • spec-schema-v1 contract (mono spec <=500 lines)
  • 547 total contracts (was 531)

Test plan

  • cargo test -p aprender-contracts --lib — lint passes
  • cargo check --workspace — clean compile
  • All 14 entity scores verified at 100/100
  • apr code -p "test" --max-turns 1 — auto-discovers model, runs inference
  • apr completions bash — generates valid completion script
  • apr man — generates valid roff man page
  • apr explain /nonexistent — exits 3 (was 0)
  • mdbook build book/ — succeeds
  • 56/56 subcommands pass all compliance gates

fix: delete flaky performance assertion from test_filter_stress_test …
dfcbe1a 
…(MUDA)

Flaky tests are waste (MUDA). The test asserted linear scaling with 10x
threshold which is timing-dependent and fails on shared CI runners.

Fix: keep correctness assertion (filter produces results, no errors),
delete performance assertion (belongs in cargo bench, not cargo test).

No CI exclusions needed — the test is now deterministic.

Updated spec with:
- Run 2 results (2026-04-09): same verdict WARN, S1/GH-707 confirmed stable FAIL
- Lessons learned: $? vs pipe exit code, lint/validate non-zero by design
- Stable PASS/FAIL/WARN categorization across 2 consecutive runs
- Updated implementation priority with enforcement status per contract
- Open work items with blocking gates and priorities

dtolnay/rust-toolchain uses branch refs (@stable, @nightly) not semver tags.
SHA pinning doesn't work because the branches move. Reverted to @stable.

Closing as stale — branch is CONFLICTING with main after 10+ PRs merged since April 9 (PRs #726, #731, #733, #734, #737, #738, #740+).

The coverage target (#715) has been met via PMAT-546 (+18 core tests) and PMAT-540 Phase 5 (+46 apr-cli tests). Entity contracts can be re-created from the branch if needed.

To recover: git diff main...fix/715-core-coverage-95 -- contracts/ to extract the entity contract YAMLs.
