From d2bbf75cac791983e2cc58d89727d216c15f8cb8 Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 23 May 2026 18:57:48 +0000 Subject: [PATCH 01/13] fix(matcher): scorecard findings unreachable due to language gate MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Recipe matcher rejected every scorecard-source finding (~310 ecosystem- wide), routing them to :control "no safe fix available" advisories. Root cause: `lib/recipe_matcher.ex` filtered candidate recipes with `"*" in langs or language in langs`. Two failure modes: 1. 12 recipes declared `languages: ["any"]` — never matched, since `"any"` is not a sentinel the filter recognises and no repo has `"any"` as its primary language. 2. 8 scorecard / workflow-file recipes declared `languages: ["yaml"]` — never matched, since yaml is a workflow-file type, not any repo's primary language. So `recipe-pin-dependencies`, `recipe-fix-workflow-permissions`, etc. were unreachable for SC013/ SC018 findings — the exact rule families dominating the daily remediation sweep. Fix: - `langs_match?/2` private helper accepts `"*"` and `"any"` as synonymous language-agnostic sentinels. - `effective_language_for/2` remaps the lookup language to `"yaml"` for patterns whose `source` is `"scorecard"` or whose `category` names a known workflow-file rule family (DependencyPinning, TokenPermissions, DangerousWorkflow, etc.). The repo's primary language is irrelevant for workflow-file findings. - Applied to `best_recipe/2`, `category_match_recipe/2`, and `fuzzy_match_recipe/2`. Tests pin all three invariants. All 22 scorecard recipe `fix_script` references already exist on disk in `scripts/fix-scripts/` — the bug was purely in matcher reachability, not missing fix implementations. Closes the dispatcher half of the "no security stuff being sorted" symptom. Remaining M7 work (PAT for cross-repo dispatch, push fixes to remotes) still needs operator action, but the manifests will now carry populated fix_script fields for scorecard findings. --- lib/recipe_matcher.ex | 42 ++++++++++++++++++++++++++----- test/recipe_matcher_test.exs | 48 ++++++++++++++++++++++++++++++++++++ 2 files changed, 84 insertions(+), 6 deletions(-) diff --git a/lib/recipe_matcher.ex b/lib/recipe_matcher.ex index 21c1d618..748fe50e 100644 --- a/lib/recipe_matcher.ex +++ b/lib/recipe_matcher.ex @@ -32,8 +32,7 @@ defmodule Hypatia.RecipeMatcher do def best_recipe(pattern_id, language) do find_recipes(pattern_id) |> Enum.find(fn recipe -> - langs = Map.get(recipe, "languages", []) - "*" in langs or language in langs + langs_match?(Map.get(recipe, "languages", []), language) end) end @@ -140,12 +139,12 @@ defmodule Hypatia.RecipeMatcher do # Match recipe by target_categories field -- most reliable match defp category_match_recipe(pattern, language) do category = Map.get(pattern, "category", "") + effective_language = effective_language_for(pattern, language) all_recipes() |> Enum.filter(fn recipe -> cats = Map.get(recipe, "target_categories", []) - langs = Map.get(recipe, "languages", []) - lang_ok = "*" in langs or language in langs + lang_ok = langs_match?(Map.get(recipe, "languages", []), effective_language) lang_ok and category in cats end) |> Enum.sort_by(fn r -> Map.get(r, "confidence", 0) end, :desc) @@ -155,6 +154,7 @@ defmodule Hypatia.RecipeMatcher do defp fuzzy_match_recipe(pattern, language) do pa_rule = Map.get(pattern, "pa_rule", "") description = Map.get(pattern, "description", "") |> String.downcase() + effective_language = effective_language_for(pattern, language) # Skip if no PA rule to match against if pa_rule == "" do @@ -162,8 +162,7 @@ defmodule Hypatia.RecipeMatcher do else all_recipes() |> Enum.filter(fn recipe -> - langs = Map.get(recipe, "languages", []) - lang_ok = "*" in langs or language in langs + lang_ok = langs_match?(Map.get(recipe, "languages", []), effective_language) recipe_pattern_ids = Map.get(recipe, "pattern_ids", []) @@ -196,6 +195,37 @@ defmodule Hypatia.RecipeMatcher do end end + # Both "*" and "any" are language-agnostic sentinels.

A fresh scan against the current tree finds 35 findings, all medium-or-lower: - 32 low (code_safety hot-path expects, ncl_docker_not_podman, workflow_audit missing-workflow, structural_drift, etc.) - 3 medium (git_state transient + structural_drift) - 0 critical, 0 high Most old baseline entries are either: - fixed in code (e.g. the believe_me at src/abi/RuleEngine.idr is now inline-suppressed with a documented `-- hypatia: allow` directive), - migrated/refactored (e.g. lib/direct_github_pr.ex no longer exists), - or were covered by the new total-Python-ban / scanner-soundness wave. Net effect: every gate threshold of "fail on critical|high above baseline" now starts from an empty critical/high ledger — net-new critical or high findings will stand out, which is what the baseline is supposed to enable. Generated with the canonical Elixir escript pipeline against this tree (no rule changes, just a snapshot refresh). Severity threshold "low" so the snapshot reflects the full advisory surface, not just gates. --- .hypatia-baseline.json | 502 ++++++++++------------------------------- 1 file changed, 125 insertions(+), 377 deletions(-) diff --git a/.hypatia-baseline.json b/.hypatia-baseline.json index c3277c30..3ef7458f 100644 --- a/.hypatia-baseline.json +++ b/.hypatia-baseline.json @@ -1,499 +1,247 @@ [ { -

Adds two new rule modules mirroring the DependabotAlerts shape: lib/rules/secret_scanning_alerts.ex (SSA001-SSA004) SSA001 — Open leaked-secret alerts (always :critical; staleness surfaced in the reason for triage prioritisation). SSA002 — Repo-level meta-finding when any open alert exists. SSA003 — Stale open alerts past the 7-day rotation threshold. SSA004 — Resolved alerts with no documented resolution vocabulary (anything outside revoked/used_in_tests/pattern_deleted/ pattern_edited). lib/rules/code_scanning_alerts.ex (CSA001-CSA004) CSA001 — Open code-scanning alerts (CodeQL + third-party SARIF including Hypatia's own `hypatia` category). Severity mapped from `security_severity_level`/`severity` onto the canonical four-bucket scale. CSA002 — Severity summary (any critical, ≥5 high, or ≥10 total). CSA003 — Stale open alerts (3/7/30/90 days by severity bucket). CSA004 — Dismissed without documented reason. Wires both into `Hypatia.CLI`: - registered in `@all_rule_modules` so the default scan includes them, - scan blocks emit normalised findings alongside the rest, - `format_module_name/1` gives them display names, - usage strings updated to list the new --rules tokens. Workflow comment in `.github/workflows/hypatia-scan.yml` updated to note that the existing `security-events: write` grant now covers all three alert APIs, not just Dependabot. No new permissions needed. Tests pin token-absent behaviour and the non-GitHub-remote error path for each module's helpers. --- .github/workflows/hypatia-scan.yml | 8 +- lib/hypatia/cli.ex | 62 +++- lib/rules/code_scanning_alerts.ex | 449 +++++++++++++++++++++++++++ lib/rules/secret_scanning_alerts.ex | 336 ++++++++++++++++++++ test/code_scanning_alerts_test.exs | 68 ++++ test/secret_scanning_alerts_test.exs | 69 ++++ 6 files changed, 988 insertions(+), 4 deletions(-) create mode 100644 lib/rules/code_scanning_alerts.ex create mode 100644 lib/rules/secret_scanning_alerts.ex create mode 100644 test/code_scanning_alerts_test.exs create mode 100644 test/secret_scanning_alerts_test.exs diff --git a/.github/workflows/hypatia-scan.yml b/.github/workflows/hypatia-scan.yml index cd38e6ce..c632a707 100644 --- a/.github/workflows/hypatia-scan.yml +++ b/.github/workflows/hypatia-scan.yml @@ -21,9 +21,11 @@ permissions: contents: read # security-events: write serves two purposes (write implies read): # 1. read — lets the built-in GITHUB_TOKEN query this repo's own - # Dependabot alerts via the Hypatia DependabotAlerts rule - # (DA001-DA004).

"No findings" looks identical whether the code is clean or the rule is broken — that ambiguity is the soundness gap. Closes it with the simplest possible mechanism: for every rule the scanner is supposed to detect, keep a known-bad sample on disk, and assert in CI that the rule fires on its sample at the expected severity. A rule that goes silent (regex drift, file pruning, packaging regression, module rename) breaks the build instead of silently weakening the estate's security posture.

The outcomes log had no way to answer "what fraction of this recipe's 'successes' were actually verified clean by post-fix re-scan?" That's the closed-loop metric this commit adds. lib/outcome_tracker.ex record_outcome/4,5 Optional `metadata` map merges into the record (under the canonical fields so a caller can't overwrite recipe_id/repo/file/outcome/ timestamp/bot by accident). record_and_verify/5 Now persists the verification verdict on every branch: verified -> success record with "verification" = "verified" still_present -> success record with "verification" = "still_present" PLUS a follow-up :false_positive record (caused_by = "post_fix_rescan") scan_failed -> success record with "verification" = "scan_failed" verify: false -> outcome record with "verification" = "unverified" The distinction between "scan_failed" and "unverified" matters: a recipe is not penalised for being run in environments without panic-attack. verification_rate/2 For a recipe_id, returns counts {verified, still_present, scan_failed, unverified} and a rate = verified / (verified + still_present). scan_failed and unverified records are excluded from the denominator so a low-verification-attempt environment doesn't artificially deflate the rate. Returns :insufficient_data below min_attempts. recipe_health/1 Aggregates across every recipe with recorded outcomes. Returns a list of maps with dispatches / successes / failures / FPs / success_rate / verification breakdown / status, sorted so the most actionable rows (quarantine_candidate, degraded) surface first. Configurable thresholds. lib/mix/tasks/hypatia.recipe_health.ex mix hypatia.recipe_health [--format json] [--only-actionable] Prints the report in a human-readable table or JSON. test/recipe_health_test.exs Pins the rate calculation (verified/still_present ratio, scan_failed + unverified excluded), the insufficient_data threshold, and the healthy/degraded/quarantine_candidate status mapping. Hand-run against the current outcomes log: 4 recipes found, all flagged :insufficient_data because the historical log was written before the verification marker existed. From the next `record_and_verify`-enabled dispatch onwards, recipes will accumulate verification data and migrate to :healthy / :degraded / :quarantine_candidate based on real evidence. --- lib/mix/tasks/hypatia.recipe_health.ex | 185 +++++++++++++++++++ lib/outcome_tracker.ex | 239 ++++++++++++++++++++++++- test/recipe_health_test.exs | 138 ++++++++++++++ 3 files changed, 556 insertions(+), 6 deletions(-) create mode 100644 lib/mix/tasks/hypatia.recipe_health.ex create mode 100644 test/recipe_health_test.exs diff --git a/lib/mix/tasks/hypatia.recipe_health.ex b/lib/mix/tasks/hypatia.recipe_health.ex new file mode 100644 index 00000000..74d4a9b1 --- /dev/null +++ b/lib/mix/tasks/hypatia.recipe_health.ex @@ -0,0 +1,185 @@ +# SPDX-License-Identifier: MPL-2.0 +# Copyright (c) 2026 Jonathan D.A.

OutcomeTracker.record_outcome_for_fix/4,5 Auto-derives `category` from the recipe registry (target_categories field) and `repo_path` from $HYPATIA_REPOS_DIR/. Always attempts re-scan verification on :success. Falls back gracefully to "verification = scan_skipped" if the recipe isn't found, so the outcome is still recorded and the gap is auditable. mix hypatia.record_outcome CLI wrapper for the bash dispatch-runner. Exit-code contract: 0 — recorded, verified-clean or scan_unavailable 2 — recorded but re-scan still finds the weak point (the runner SHOULD treat the batch as failed and consider rollback) 1 — bad arguments / unrecoverable error The non-zero exit on still_present is what lets bash notice a false-fix without parsing JSON. In-tree callers of record_outcome/4,5 stay as-is: learning_scheduler's fleet-outcome replay and batch_rollback's mark-as-false-positive are both legitimately unverified paths.

Builds the escript fresh, scans the fixtures tree with the built binary, asserts every manifest entry fires at the expected severity. Catches the failure mode where rule sources are correct but the escript build/packaging drops them. The gate caught a latent bug on its first end-to-end run: lib/hypatia/cli.ex:726 @language_extensions was missing .agda, .zig, .thy, .fst/.fsti, .adb/.ads. The patterns_for_language/1 dispatcher in lib/rules/code_safety.ex defines rules for agda/zig/isabelle/ fstar/ada — but because the CLI's directory walker had no extension-to-language mapping for those files, the rules NEVER FIRED on real scans. This is the exact PR #278 class: the engine knows the rule, the rule's regex works, but the wiring never gives the rule any input. Added all 7 missing language → extension mappings. Re-run shows agda_postulate and zig_ptr_cast (previously silent) now flag at the expected severity. test/soundness/run-escript-soundness.sh Builds escript, scans test/soundness/fixtures, asserts every manifest entry fires. Exits non-zero on the first regression with a "PR #278 class" diagnostic message pointing the reader at the escript build (mix.exs:escript, hypatia-cli.sh). .github/workflows/tests.yml New step "Escript packaging soundness" on the e2e-elixir job, after the existing E2E test suite. Re-uses the same setup-beam + cache + deps.get, no extra runtime cost beyond the escript build. Hand-run on the current tree: 14/14 fixtures fire at expected severity on the built escript. --- .github/workflows/tests.yml | 9 ++ lib/hypatia/cli.ex | 6 ++ test/soundness/run-escript-soundness.sh | 138 ++++++++++++++++++++++++ 3 files changed, 153 insertions(+) create mode 100755 test/soundness/run-escript-soundness.sh diff --git a/.github/workflows/tests.yml b/.github/workflows/tests.yml index 18311f19..33517e61 100644 --- a/.github/workflows/tests.yml +++ b/.github/workflows/tests.yml @@ -51,6 +51,15 @@ jobs: - name: Run E2E test suite run: bash tests/e2e.sh + - name: Escript packaging soundness + # PR #278 documented that the rule definitions can be correct + # but the *packaged escript* can silently drop entire rule + # families.

The dispatcher now consults the verification rate before auto-executing and downgrades to :review (rhodibot PR for human inspection) if the recipe is unhealthy. OutcomeTracker.quarantined?/2 Cheap predicate derived from existing verification data — no new GenServer or state. Returns true iff: - verification rate < :threshold (default 0.30), AND - verifiable-outcomes count >= :min_attempts (default 5) Honours HYPATIA_RECIPE_QUARANTINE_DISABLE=true env override (logged when used so audit history captures the bypass). Recipes with no verification data are NOT quarantined — gating them would create a chicken-and-egg where new recipes can never accumulate the data needed to leave quarantine. fleet_dispatcher.ex do_eliminate_dispatch(:auto_execute, ...) now checks quarantined? before dispatching to robot-repo-automaton. On quarantine, it recurses with :review so rhodibot opens a PR instead. The fix gets surfaced for human review; it doesn't get suppressed. test/recipe_health_test.exs Three new tests pin the invariants: - quarantined? returns true on rate < 0.30 with >= 5 verifiable - quarantined? returns false on insufficient data (chicken-and-egg) - HYPATIA_RECIPE_QUARANTINE_DISABLE env override is honoured Net effect: once `record_outcome_for_fix` is wired into the dispatch- runner and verification data starts flowing, any recipe that drifts toward false fixes silently becomes "review-only" without operator intervention.

Whole-tree scanning of the fixtures directory can't surface these — workflow_audit doesn't recurse into subdirs looking for .github/. Needs per-fixture scan-root. git_state, honest_completion Transient / git-state dependent — hermetic fixtures are hard. dependabot_alerts, secret_scanning_alerts, code_scanning_alerts GitHub API queries — no "known-bad sample on disk" model applies.

README updated with a per-family table and a suggested Phase 2 design (extend manifest with `scan_root` field, scan per-fixture-directory instead of one tree-scan).

Eight events covering every observable decision in the pipeline: :scan, :complete (duration_ms, finding_count) :dispatch, :decision (strategy, tier, recipe_id, repo) :outcome, :recorded (recipe_id, repo, outcome, verification) :verification, :result (recipe_id, repo, verdict) :quarantine, :triggered (kind, id, reason, level) :rate_limit, :exceeded (bot, scope) :neural, :cycle (duration_ms) :soundness, :violation (rule_module, rule_id) Hand-written emit helpers per event (not meta-programmed) so each call site shows what it's saying. `:telemetry.execute/3` is wrapped in `safe_execute/3` so a missing `:telemetry` module (escript-only builds, stripped releases) is a no-op rather than a crash — instrumentation must never break the host. `all_events/0` exposes the full list so the watcher / Prometheus exporter / alerting layer can subscribe via attach_many. Instrumented sites: lib/hypatia/cli.ex — scan_complete with elapsed time lib/fleet_dispatcher.ex — dispatch_decision on each tier (+ quarantine_triggered + downgrade marker when auto_execute degrades to review) lib/outcome_tracker.ex — outcome_recorded on every write, verification_result on every verify_fix, quarantine_triggered when recipe crosses verification-rate threshold No new runtime dependency: :telemetry is already a transitive dep of phoenix + bandit. Calls are no-ops when no handler is attached, so this commit on its own changes nothing about runtime behaviour — it just makes the upcoming watcher (commit 2/4), JSON API endpoint (commit 3/4), and `mix hypatia.watch` TUI (commit 4/4) possible. Refactored OutcomeTracker.verify_fix into a public telemetry-emitting wrapper around the original `do_verify_fix` private impl, so the verification event fires regardless of caller and the implementation stays unchanged. --- lib/fleet_dispatcher.ex | 22 +++++++ lib/hypatia/cli.ex | 7 +++ lib/hypatia/telemetry.ex | 125 +++++++++++++++++++++++++++++++++++++++ lib/outcome_tracker.ex | 28 +++++++++ 4 files changed, 182 insertions(+) create mode 100644 lib/hypatia/telemetry.ex diff --git a/lib/fleet_dispatcher.ex b/lib/fleet_dispatcher.ex index a092828f..5812060a 100644 --- a/lib/fleet_dispatcher.ex +++ b/lib/fleet_dispatcher.ex @@ -279,8 +279,30 @@ defmodule Hypatia.FleetDispatcher do # so rhodibot opens a PR for human inspection.

No external deps — uses IO.ANSI for cursor positioning so it works over plain SSH with zero terminfo/curses requirements. Two operating modes: Local attaches to Watcher in the same BEAM (default) Remote polls http://127.0.0.1:9090/api/status (via --url) Modes are interchangeable — same snapshot shape from either source. --url makes it possible to watch a remote Hypatia via an SSH tunnel without spinning up a local node. Display (refresh every 2s by default): - Uptime - Event counts in the 5min + 1hr windows, sorted by count - GenServer queue depths (yellow > 10, red > 100) - Dropped-event warning when back-pressure has kicked in - Last-updated timestamp Flags: --interval SECONDS refresh rate (default 2) --url URL poll HTTP /api/status instead of local --once render once and exit (good for cron) --plain suppress ANSI cursor (pipe-safe) test/watch_task_test.exs Three tests via ExUnit.CaptureIO: - render/3 produces dotted-string event names in the output - :unavailable snapshot shows the actionable error message - dropped_events > 0 fires the back-pressure warning render/3 is exposed publicly (was defp) so the test can exercise the formatting end-to-end without going through Mix.Task plumbing. Smoke-tested against a real Watcher with all 5 instrumented event kinds; output renders cleanly with bold headers, dim dividers, aligned counters, and the expected colour coding. This closes Phase 1 of the watcher / supervision plan: 1/4 ✓ telemetry instrumentation (d0ddd2f) 2/4 ✓ Watcher GenServer + ETS aggregator (3b4379e) 3/4 ✓ /api/* loopback-only endpoints (30ced35) 4/4 ✓ mix hypatia.watch CLI (this commit) Phase 2 (web dashboard + SSE stream + Prometheus endpoint) and Phase 3 (alerts + persistence + anomaly detection) remain. --- lib/mix/tasks/hypatia.watch.ex | 214 +++++++++++++++++++++++++++++++++ test/watch_task_test.exs | 66 ++++++++++ 2 files changed, 280 insertions(+) create mode 100644 lib/mix/tasks/hypatia.watch.ex create mode 100644 test/watch_task_test.exs diff --git a/lib/mix/tasks/hypatia.watch.ex b/lib/mix/tasks/hypatia.watch.ex new file mode 100644 index 00000000..9cfd8eda --- /dev/null +++ b/lib/mix/tasks/hypatia.watch.ex @@ -0,0 +1,214 @@ +# SPDX-License-Identifier: MPL-2.0 +# Copyright (c) 2026 Jonathan D.A.
