From 4920952f783a67c19730fbcead82769fd095c5f9 Mon Sep 17 00:00:00 2001 From: Matt <47545907+SoundMatt@users.noreply.github.com> Date: Wed, 29 Jul 2026 08:55:28 -0700 Subject: [PATCH] fix: bump rsfusa to v0.3.14 and make the safety-analysis pipeline real MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The rust-FuSa CLI (rsfusa) was pinned to a stale v0.3.10 while the config schema, HARA schema, and stub-detection rules it enforces had moved on several releases (v0.3.11-v0.3.14). Every core safety command in CI was failing on a config parse error and being masked green by `|| true` on every step, so the "ASIL-B safety (rust-FuSa)" job had been running none of its actual workload for some time. - Bump the rsfusa pin to v0.3.14 (current latest release) in both ci.yml and the new release.yml. - Fix .fusa.json to the current config schema (configVersion/project object/standard) so rsfusa can parse it at all (#13, #19). - Rewrite .fusa-hara.json to the current operationalSituations/hazards/ safetyGoals schema, with ASIL letting the tool derive it from S/E/C against the literal ISO 26262-3 Table 4 rather than a hand-typed value (several hazards' previously-claimed ASIL-B did not actually match their own S/E/C under the real table) (#14). - Add the 15 REQ-VIRT-013..019 / REQ-MASTER-006..013 requirement IDs that were tagged in code/tests but missing from .fusa-reqs.json and requirements.json (#18). - Remove `|| true` from every safety-job step now that its root cause (the config parse failure) is fixed, so a real regression fails CI instead of being silently swallowed (#13). - Fix real `check --strict` findings the newer rsfusa content-quality rules surface instead of suppressing them: replace production-code .unwrap() with .expect("..."), replace test-code .unwrap() with .expect() carrying a rationale (rule LINT002's own remediation), reduce several genuine nesting-depth hot spots (rule ANA002) by extracting helper functions, add `#![forbid(unsafe_code)]` (LINT006), and annotate/fix the truncating-cast sites the tool flags (ANA005) — including making an LDF frame-ID parse fail cleanly instead of silently truncating out-of-range IDs. - Add the missing `rsfusa coupling` step (ISO 26262-6 §6.4.4 evidence the gap report requires but CI never generated). - Gate CI on `rsfusa safety-case`'s missing-required-evidence warning and on `rsfusa qualify`'s qualification badge, and reorder the safety job so qualify/release run before safety-case/iso26262 (both check for qualify-report.json/sbom.json's presence) (#15). - Supply `rsfusa qualify` real qualification metadata (--qualification-method self --qualifier ... --record-uri ...) so the badge reflects the project's actual self-qualification process instead of always reading "unqualified" regardless of pass rate (#15). - Fix the coverage step's broken percentage extraction and turn the claimed "must be >= 90%" comment into a real gate at the current ~85% baseline, to be ratcheted up over time (#16). - Keep `rsfusa verify` non-blocking (a real upstream rust-FuSa bug: it invokes `cargo test -- --test-output=immediate`, a libtest flag that does not exist) but make the skip loud via a `::warning::` annotation instead of a silent `|| true` (#13). - Fix a doc comment in integration_test.rs whose literal `//fusa:test` substring was being parsed by `rsfusa trace` as a malformed annotation. - Add release.yml: attach sbom.json/provenance.json/artifact-manifest.json to the GitHub Release on publish, so supply-chain evidence is discoverable per-release instead of only inside an ephemeral CI workflow-run artifact bundle (#17). - Update tool-qualification/rsfusa-tql2.md's version/qualification-method claims to match reality. Closes #13, #14, #15, #16, #17, #18, #19, #21.
