From edc479d15e799345f6cc05eb5e89d63b9b9b7f6e Mon Sep 17 00:00:00 2001 From: matedev01 Date: Fri, 7 Aug 2026 16:33:31 +0200 Subject: [PATCH] feat: persistent agent memory + review-policy migration; openvang rebrand Second slice of the local branch (runtime landed in the prior PR). Three coherent-but-interwoven changes that touch the same core files and so land together: - Persistent memory: benchmark/memory.py + source_memory.py + memory_coverage.py + ablation.py, threaded through agent/context.py, benchmark/runner.py, and scripts/run_eval.py, with a receipt-safe memory_commitment bound into benchmark/attestation.py (never binds raw recalled content). Memory-coverage and ablation protocols + their CLIs and tests. - Review-policy migration: REVIEW.md + CONTRIBUTING.md content moves into specs/009-agent-review; CODEOWNERS, the PR template, and the review scripts (agent/review.py, review_pr.py, benchmark_pr_policy.py, pr_reopen_policy.py) updated to match. - Identity: pyproject authors + URLs move gittensor-vanguard -> openvang, completing the org transfer. Blog posts are kept (only spec-driven-development.md is content-updated). Rebased onto the runtime PR's test; inherits its cryptography CI install. --- .github/CODEOWNERS | 2 +- .github/PULL_REQUEST_TEMPLATE.md | 13 +- .github/workflows/agent-benchmark-smoke.yml | 4 +- .github/workflows/pr-limit.yml | 2 +- .github/workflows/pr-target-check.yml | 4 +- AGENTS.md | 96 +- CHANGELOG.md | 6 - CONTRIBUTING.md | 142 --- README.md | 81 +- REVIEW.md | 172 --- ROADMAP.md | 217 ++-- agent/context.py | 150 +++ agent/decider.py | 22 +- agent/philosophy.py | 14 +- agent/planner.py | 12 +- agent/review.py | 4 +- benchmark/ablation.py | 327 +++++ benchmark/attestation.py | 28 +- benchmark/memory.py | 1208 +++++++++++++++++++ benchmark/memory_coverage.py | 97 ++ benchmark/memory_quality_protocol.json | 21 + benchmark/runner.py | 88 +- benchmark/source_memory.py | 232 ++++ benchmark/tee_validator_archive.py | 1 + blog/spec-driven-development.md | 26 +- docs/architecture.md | 291 ++--- docs/attested-image-publishing.md | 4 +- docs/memory-ablation.md | 76 ++ docs/persistent-memory.md | 96 ++ docs/spec-driven-development.md | 8 +- pyproject.toml | 8 +- scripts/benchmark_pr_policy.py | 4 +- scripts/leaderboard_feed.py | 12 +- scripts/pr_reopen_policy.py | 2 +- scripts/review_pr.py | 2 +- scripts/run_attested_eval.py | 75 +- scripts/run_eval.py | 59 + scripts/run_memory_ablation.py | 167 +++ scripts/run_memory_coverage.py | 85 ++ scripts/score_pr_delta.py | 6 +- specs/009-agent-review/spec.md | 4 +- specs/011-miner-manifest/spec.md | 2 +- tests/test_context.py | 22 + tests/test_leaderboard_feed.py | 29 + tests/test_memory_ablation.py | 120 ++ tests/test_memory_coverage.py | 49 + tests/test_persistent_memory.py | 401 ++++++ tests/test_run_attested_eval.py | 40 + tests/test_run_eval.py | 91 ++ tests/test_run_memory_ablation.py | 111 ++ tests/test_run_memory_coverage.py | 46 + tests/test_runner.py | 93 ++ tests/test_source_memory.py | 153 +++ tests/test_spec_008_philosophy.py | 2 +- tests/test_spec_075_attestation.py | 2 +- vanguarstew_agent_files.json | 2 +- 56 files changed, 4189 insertions(+), 842 deletions(-) delete mode 100644 CONTRIBUTING.md delete mode 100644 REVIEW.md create mode 100644 benchmark/ablation.py create mode 100644 benchmark/memory.py create mode 100644 benchmark/memory_coverage.py create mode 100644 benchmark/memory_quality_protocol.json create mode 100644 benchmark/source_memory.py create mode 100644 docs/memory-ablation.md create mode 100644 docs/persistent-memory.md create mode 100644 scripts/run_memory_ablation.py create mode 100644 scripts/run_memory_coverage.py create mode 100644 tests/test_memory_ablation.py create mode 100644 tests/test_memory_coverage.py create mode 100644 tests/test_persistent_memory.py create mode 100644 tests/test_run_memory_ablation.py create mode 100644 tests/test_run_memory_coverage.py create mode 100644 tests/test_source_memory.py diff --git a/.github/CODEOWNERS b/.github/CODEOWNERS index 0485efa6..44ff1837 100644 --- a/.github/CODEOWNERS +++ b/.github/CODEOWNERS @@ -1,2 +1,2 @@ -# Default reviewer for all changes.

Use the exported -`EXAMPLE_REPO_SET` to load the shipped example explicitly. - -```python -from benchmark.repo_set import CURATED_REPO_SET, EXAMPLE_REPO_SET, load_repo_set -rs = load_repo_set(CURATED_REPO_SET) # operational vetted set -# rs = load_repo_set(EXAMPLE_REPO_SET) # schema starter only -tuned = [e.source for e in rs.tuned()] -heldout = [e.source for e in rs.held_out()] -``` - -CLI replay from a repo set (clone listed repos locally, or use https sources to auto-clone): - -```bash -VANGUARSTEW_OFFLINE=1 python -m scripts.run_eval \ - --repo-set benchmark/repo_sets/curated.json --tasks 2 --horizon 5 - -# held-out slice only (--held-out is shorthand for --repo-set-partition held_out) -python -m scripts.run_eval --repo-set benchmark/repo_sets/curated.json --held-out --tasks 2 --horizon 5 - -# every entry in the config -python -m scripts.run_eval --repo-set benchmark/repo_sets/curated.json --repo-set-partition all --tasks 2 --horizon 5 +) ``` -The runner loads the config through `load_repo_set()`, replays the selected slice, and applies -each entry's `freeze_window` hints (`recent_bias`, `rotation_seed`, `after`, `before`, -`min_history`) to task selection. The checked-in `example.json` remains schema-valid but -**must** fail at execution time because its `OWNER/...` sources are placeholders, not vetted repos. -## Leakage defenses - -Because the reference is public GitHub history, the benchmark actively resists leakage: - -- **No internet in the sandbox** beyond the managed inference proxy. -- **Knowable-at-T only** — the frozen context is built from commits/issues/PRs/releases that - existed at T; nothing created (or a release published) after T is included. -- **As-of-T reconstruction of mutable fields** (`benchmark/github_context.py`) — some GitHub - fields the live REST snapshot exposes are mutable and would otherwise leak present-day state: - - *Milestone state* is derived from `created_at`/`closed_at` (`_milestone_at`) — `"closed"` - only when it was already closed by T. - - *Issue/PR label membership* is reconstructed by replaying the item's timeline - `labeled`/`unlabeled` events up to T (`_labels_at`); when the timeline can't be read - (offline, rate-limited, or no label events), labels are **omitted** (`labels_as_of_t: - false`) rather than copied live — fail-closed, never leak. Consumers must treat - `labels` as historically exact **only when** `labels_as_of_t` is true; `labels_as_of_t: - false` means "label history unavailable", not "this item had no labels at T". The - agent-facing prompt view follows that contract by omitting `labels` on such items. - - *Intentionally omitted* (not reconstructable from a cheap as-of-T source): the repo-wide - label catalog, milestone `due_on` and `title`, and the release display `name` are dropped - from the enriched context rather than copied live — milestones and releases expose no edit - stream to replay, so a post-T retitle would leak future direction (only the immutable - milestone `number` and release `tag`/`published_at` are kept). -- **Forward-reference scrubbing** (`benchmark/leakage.py`) — even within knowable-at-T text, - issue/PR back-references (`#N`), GitHub issue/PR/commit links, and raw SHAs are masked, so a - commit subject or README can't cross-reference the future. -- **As-of-T field guards** (`benchmark/github_context.py`) — mutable API fields such as - milestone `state` are derived from timestamps (`closed_at` vs. T), not copied from the live - response. Fields the REST API cannot time-filter (the repo label catalog, milestone - `due_on`/`title`, release `name`) are omitted from the frozen context rather than carried - as present-day snapshots. -- **Recent-window + rotation** freeze-point selection (`benchmark/taskgen.py`) — prefer recent - points (past a model's training cutoff) and rotate deterministically so answers aren't reused. -- **Judge-order telemetry** (`benchmark/judge.py`, `benchmark/runner.py`) — replay artifacts - persist each row's `judge_order` plus aggregate `judge_order_stats`, including - `disagreement_rate` when dual-order judging is enabled. If that rate rises, treat it as - a judge-stability warning worth inspecting for prompt/model drift or noisier scoring, not - as evidence that challenger and baseline are necessarily converging. -- **Repo diversity / held-out repos** (M3) — generalization is scored on unseen repos. - -### Forward-reference scrubbing policy - -`strip_forward_refs()` (`benchmark/leakage.py`) neutralizes future-pointing references in the -free-text fields of the frozen context (commit subjects, issue/PR titles, README excerpt, -release/milestone names). It masks exactly three things: - -- **Issue/PR back-references** — `#123` → `#ref`. -- **GitHub deep links** — `https://github.com/owner/repo/{issues,pull,commit,compare}/…` → ``. -- **Raw commit SHAs** — a 7–40 char hex token → ``, **but only when it contains a hex - letter (`a`–`f`)**. - -**Why bare numeric tokens are preserved:** a SHA's alphabet `[0-9a-f]` is a superset of the -digits, so an all-numeric token (a count, a percentage, a year like `2024`, a version part) is -indistinguishable from a short hex SHA by shape alone. Masking those would corrupt legitimate -numeric content the agent needs, so `_looks_like_sha()` requires at least one `a`–`f` letter -before a token is treated as a SHA. The trade-off is deliberate: an all-numeric SHA-shaped -token is left intact rather than risk shredding real numbers — masking is scoped to tokens that -are *unambiguously* hex. - -This policy is pinned by regression tests in `tests/test_leakage.py`: -`test_strip_forward_refs_masks_refs_links_and_shas`, -`test_strip_forward_refs_preserves_plain_numbers`, and -`test_strip_forward_refs_still_masks_hex_shas_among_plain_numbers` (hex SHAs are still masked -even when surrounded by plain numbers). Changes to the masking behavior should update these -tests and this note together. - -## Principle - -Create a new repo only when it has real content to hold.
