…Phase 3) Verify that rivet get works and that every command accepting --format json produces valid JSON output. Adds individual tests for coverage, matrix, next-id, schema show/links/rules/info, and get --format yaml, plus a sweep test that validates all JSON-producing commands in a single pass.

Add missing security analysis artifacts identified in the STPA-Sec review of the MCP server attack surface: two security UCAs covering unauthenticated tool invocation and path disclosure in errors, one loss scenario for malicious VS Code extension exploitation, and one security constraint requiring path sanitization. Implements: SUCA-MCP-1, SUCA-MCP-2, SLS-IMPL-001, SSC-IMPL-006 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

…e 4) Add EU AI Act compliance page to the multi-page HTML export and the single-page renderer. When the eu-ai-act schema is loaded, the page shows per-section coverage, missing artifact types, and an artifact inventory grouped by Annex IV section. When the schema is not loaded, a brief "not configured" message is shown instead. The sidebar nav conditionally includes the EU AI Act link (like STPA).

Mount an MCP-over-HTTP endpoint at /mcp on the dashboard server using rmcp's StreamableHttpService. The endpoint runs in stateless mode with JSON responses so a simple POST suffices — no SSE framing needed for request/response tools. Each request snapshots the dashboard's current store/schema/graph into a fresh RivetServer, so dashboard reloads are picked up automatically. Implements: FEAT-049 Refs: #98 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

…e coverage Add constraint-satisfies links from requirements to all 35 system constraints and 62 controller constraints, fixing the two stpa-dev bridge rules that were at 0% coverage. Add 3 MCP server UCAs (UCA-M-1..3) and 3 corresponding controller constraints (CC-M-1..3) covering stale state, partial loads, and pre-validation coverage. Register mcp-ucas in stpa.yaml yaml-sections. Update rivet.yaml trace-exempt-artifacts for new STPA IDs. Overall coverage: 83.7% -> 99.8% (596/597 rules covered). Satisfies: SC-1, SC-2, SC-3, SC-4, SC-5, SC-6, SC-7, SC-8, SC-9, SC-10 Satisfies: SC-11, SC-12, SC-13, SC-14, SC-15, SC-16, SC-17, SC-18, SC-19 Refs: SC-IMPL-003, H-IMPL-003 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

… map Expand AGENTS.md commit traceability section with a trailer reference table, artifact selection guide, and a retroactive traceability map covering 18 orphan commits (PRs #28 through #124) that predate strict trailer enforcement. Restructure CLAUDE.md to prominently feature commit trailer requirements as mandatory, with a quick-reference lookup for common artifact IDs by work area. This addresses the 41 orphan commits (36% of total) by documenting their artifact relationships for audit purposes without rewriting git history, and ensures future commits follow the trailer convention.

Add undeclared fields to stpa.yaml and dev.yaml schemas to match actual data usage, eliminating all "field not defined in schema" INFO-level diagnostics (194 -> 59, remaining 59 are traceability rules). stpa.yaml: - uca: add control-action (string) field - loss-scenario: add type (alias for scenario-type) and process-model-flaw (text) - controller: add type (alias for controller-type), control-actions and feedback (list<mapping>) dev.yaml: - design-decision: add decision (text) field Fixes #125 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

…ests Add spar as a cross-repo external dependency in rivet.yaml, with both a git URL (matching the Cargo.toml rev) and a local path fixture for development/testing. Fix a bug where internal link targets within external projects were not being prefixed when loaded into the store, causing false broken-cross-ref validation failures. - Add spar external config to rivet.yaml (git + local path) - Create test fixture at tests/fixtures/spar-external/ with 4 artifacts - Add 6 integration tests in externals_sync.rs covering sync, load, cross-repo link resolution, backlinks, and dogfood config parsing - Fix ProjectContext::load to prefix external-internal link targets Implements: FEAT-020 Refs: REQ-020 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Both `rivet stats` and `rivet stats --format json` previously computed their output independently — text via `print_stats` and JSON via inline code. While both ultimately called `store.len()`, the separate code paths could diverge if `by_type` got out of sync with the `artifacts` HashMap (e.g. after a type-change upsert left a phantom empty-vector entry in `by_type`). Changes: - Extract `compute_stats()` that both text and JSON paths consume, deriving the total as the sum of per-type counts rather than from `store.len()` directly. - Fix `Store::upsert` to remove the old type key from `by_type` when its vector becomes empty, preventing phantom zero-count types. - Add `Store::types_total()` for cross-check convenience. - Add 4 tests: 2 in `rivet-core` (store consistency) and 2 in `rivet-cli` (stats total == sum of type counts, including after type-change).

Add --list flag to `rivet docs` command so both `rivet docs` and `rivet docs --list` list available topics. Fix LSP server shutdown deadlock where io_threads.join() blocked because the connection sender channel was never closed. Add 5 LSP integration tests that spawn `rivet lsp` as a subprocess, communicate via JSON-RPC over stdio, and verify: initialize handshake with capabilities, diagnostics on didOpen with broken links, documentSymbol response, clean shutdown, and error diagnostics for unknown artifact types.

The salsa validation path manually collected schema contents without calling load_schema_contents(), skipping bridge auto-discovery. This caused 98 warnings about constraint-satisfies link type not being defined. Now uses the same path as --direct.

The `if` field must be inside individual hooks, not at the group level. Uses `rivet stamp all` (available in installed binary) instead of `rivet provenance mark` (PR #125 not yet merged).

Add a complete s-expression filter/constraint language for artifact querying. Rowan-based lossless CST parser with error recovery, typed AST evaluator supporting 20 predicates (logical connectives, comparisons, collection membership, link traversal, regex matching), and CLI --filter integration on list, stats, and coverage commands. New artifacts for v0.4.0 variant/PLE system: 6 requirements (REQ-041..046), 4 design decisions (DD-048..051), 9 features (FEAT-106..114), and full STPA analysis with 7 hazards, 7 system constraints, 5 UCAs, 5 controller constraints, and 4 loss scenarios in safety/stpa/variant-hazards.yaml. Examples: rivet list --filter '(= type "requirement")' rivet list --filter '(and (has-tag "stpa") (= status "approved"))' rivet stats --filter '(= type "feature")' rivet coverage --filter '(has-tag "safety")' Implements: REQ-041 Refs: FEAT-106, FEAT-107, FEAT-108 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Add s-expression filter support to the /api/v1/artifacts endpoint via ?filter= query parameter. Parsed once before iterating, composes with existing ?type=, ?status=, ?q= parameters. Add runtime-evidence artifact type to eu-ai-act.yaml addressing Art. 12(2) tamper-evident runtime logging requirements (per #99 feedback from @jagmarques). Includes hash-chain integrity via previous-digest, cosign/sigstore signature support, and new monitoring-has-evidence traceability rule.

MCP server now exposes full CRUD: rivet_add (existing), rivet_modify (change status/title/tags/fields), rivet_link/rivet_unlink (manage links between artifacts), and rivet_remove (delete artifacts). All tools wrap the existing rivet-core::mutate module with schema validation. Add scripts/install-hooks.sh that installs commit-msg (trailer validation) and pre-commit (rivet validate) git hooks.

Add FilterInput salsa input, parse_filter_expr tracked function (caches the s-expression parse), and filter_artifact_ids tracked function that returns matching artifact IDs. Returns Vec<String> instead of Store to satisfy salsa's PartialEq requirement on tracked return types. The parse result is memoized — the same filter string across multiple validation cycles only parses once. When source files change, salsa recomputes the filtered set incrementally.

Add --hooks flag to rivet init that installs git hooks (commit-msg for trailer validation, pre-commit for rivet validate). Hooks chain with existing hooks via .prev backup files for coexistence with husky, pre-commit, lefthook, etc. Add rivet_query MCP tool that accepts an s-expression filter and returns matching artifacts with full details.

Addresses three gaps found in the post-v0.4.0 dogfooding audit. **v0.4.0 shipped-work artifacts** — `artifacts/v040-features.yaml` was last touched 2026-04-12 and describes variant/PLE work (FEAT-106..114), not the verification pyramid that actually shipped on 2026-04-19. New file `artifacts/v040-verification.yaml` authors 4 design decisions (DD-052 four-layer verification pyramid, DD-053 suffix-based yaml-section matching, DD-054 non-blocking framing for formal CI jobs, DD-055 cfg-gate platform syscalls), 8 features (FEAT-115..122 covering Kani 27-harness expansion, differential YAML tests, operation-sequence proptest, STPA-Sec suite, suffix-based UCA extraction, nested control-action extraction, Zola export, Windows support), and 1 requirement (REQ-060 cross-platform binaries). Counts were verified against the actual codebase — 27 `#[kani::proof]` attrs in proofs.rs, 6 differential tests, 16 STPA-Sec tests. **Retroactive trailer map** — extended `AGENTS.md` with three more legacy orphans (51f2054 #126, f958a7e, 75521b8 #44), a new v0.4.0 PR-level section for #150/#151/#152/#153, and an honest "genuinely-unmappable" section calling out `ca97dd9f` (#95) whose `SC-EMBED-*` trailers point to artifacts that were never authored. **Verus Proofs → hard gate** — rules_verus PR #21 (merged as 5bc96f39) fixes the hub-repo's ambiguous `:all` alias by emitting proper `toolchain()` wrappers per platform. Updates the git_override pin from e2c1600a (Feb 2026, broken) to 5bc96f39 and removes `continue-on-error: true` from the Verus job. Implements: REQ-030, REQ-060 Refs: DD-052, DD-053, DD-054, DD-055, FEAT-115, FEAT-116, FEAT-117, FEAT-118, FEAT-119, FEAT-120, FEAT-121, FEAT-122 Verifies: REQ-030

…, v0.4.0 artifacts (#155) * fix(ci): make Kani, Rocq, and Mutation Testing real hard gates Audit found that all four verification-pyramid CI jobs were silently failing on main. None had ever run green. This fixes three and scopes the fourth to an upstream bug. **Kani Proofs** — flipped to hard gate. Five harnesses in rivet-core/src/proofs.rs were initializing `EvalContext` with only `artifact` + `graph` fields after the struct grew a `store: Option<...>` field for quantifier support. The cfg(kani) gate meant the break was invisible to normal `cargo check`. Added `store: None` to all five. **Rocq Proofs** — flipped to hard gate. The `rocq_library` target `rivet_metamodel` had `srcs = []`, which fails Bazel analysis with "rocq_library requires at least one source file". Removed the empty aggregator target and pointed the test at the two real libraries (Schema + Validation) directly. **Mutation Testing** — split into a per-crate matrix so rivet-core and rivet-cli each get a 45-minute budget. Previously both crates shared a single 40-minute timeout, causing rivet-core to be cancelled before finishing and rivet-cli to never run. `--timeout` per-mutant reduced from 120s to 90s. Uploads are now per-crate artifacts. **Verus Proofs** — left as continue-on-error with a pointer comment. Root cause is in rules_verus (pulseengine/rules_verus, commit e2c1600): the hub repository's `:all` alias only points to the first platform's toolchain rather than registering `toolchain()` rules for each platform, so `register_toolchains("@verus_toolchains//:all")` resolves to a non-toolchain target. Fixing this requires an upstream change to rules_verus. With these fixes, CI will fail — honestly — on Kani regressions, Rocq proof breaks, and surviving mutants, instead of silently reporting green. Implements: REQ-010, REQ-029 Verifies: REQ-010 * perf(serve): enforce node budget on /graph to prevent 57s render The /graph dashboard route previously ran layout + SVG over the full link graph (~1800 artifacts on the dogfood dataset), taking ~57s and producing ~1MB of HTML. The Playwright test at graph.spec.ts:17 was named "node budget prevents crash on full graph" but grepping the renderer for budget/max_nodes returned zero matches -- the budget was aspirational. This commit adds a real safety valve in render_graph_view: - DEFAULT_NODE_BUDGET = 200, MAX_NODE_BUDGET = 2000 (hard ceiling). - After the filtered subgraph is built but before the expensive pgv_layout + render_svg calls, short-circuit with a budget message when node_count > budget. - The message contains the literal string "budget" so the Playwright locator `svg, :text('budget')` matches and exposes the standard filter form (types / focus / depth / link_types / limit) so users can scope the view without editing URLs. - Per-request override via ?limit=NNN, clamped to [1, MAX_NODE_BUDGET]. - Filtered views under the budget (?types=requirement, ?focus=REQ-001&depth=2) continue to render SVG unchanged. Perf (release build, rivet dogfood dataset via serve_integration test): before after GET /graph ~57s / ~1MB ~1ms / 20KB GET /graph?types=requirement (filtered) ~1ms / 44KB (SVG) GET /graph?focus=REQ-001&depth=2 (filtered) ~44ms / 67KB (SVG) Three new integration tests in serve_integration.rs lock in the invariant: full graph stays under 5s and returns the budget message, focused view still renders SVG, and ?limit=1 forces the budget path. Implements: REQ-007 * feat(ple): feature model + variants for rivet itself (dogfooding #128) Ship a feature model that describes the real variability in rivet: compile-time cargo features, CLI deployment surfaces (cli / dashboard / LSP / MCP), built-in adapters, export formats, test-import formats, and init presets. Every declared feature maps 1:1 to something grep-able in the code: a cargo feature flag, a `rivet` subcommand, a format string dispatched by `export --format` / `import-results --format`, or an init preset in `resolve_preset()`. Closes the dogfooding gap for #128 — v0.4.0 shipped `rivet variant check`, but the rivet project itself had no feature model to feed it. Files: * artifacts/feature-model.yaml — root feature tree + constraints * artifacts/variants/minimal-ci.yaml — default-features cargo build, CLI-only deployment (what CI runs) * artifacts/variants/full-desktop.yaml — every surface, every preset, wasm + oslc cargo features on Real variability identified: * yaml-backend alternative (rowan-yaml default, serde-yaml-only fallback) * deployment-surface or-group (cli-only, dashboard, lsp-server, mcp-server) * adapters or-group with cargo-feature constraints (implies oslc-client feat-oslc; implies wasm-adapter feat-wasm) * export-formats / test-import-formats / init-presets or-groups * preset ↔ adapter constraints (preset-aadl implies aadl-adapter; preset-stpa implies stpa-yaml-adapter) * dashboard implies html-export (shared HTML pipeline) * reqif-export implies reqif-adapter (shared reqif module) Verification (both variants pass): $ rivet variant check --model artifacts/feature-model.yaml \ --variant artifacts/variants/minimal-ci.yaml Variant 'minimal-ci': PASS Effective features (40): aadl-adapter, adapters, baselines, cli-only, commits, core, coverage, deployment-surface, docs-cli, export-formats, generic-yaml-adapter, generic-yaml-export, hooks-infra, html-export, impact-analysis, init-presets, junit-adapter, junit-import, matrix, mutations, needs-json-adapter, needs-json-import, optional-cargo-features, preset-aadl, preset-dev, preset-stpa, query, reqif-adapter, reqif-export, rivet, rowan-yaml, schema-system, sexpr-language, snapshots, stpa-yaml-adapter, test-import-formats, validate, variant-mgmt, yaml-backend, zola-export $ rivet variant check --model artifacts/feature-model.yaml \ --variant artifacts/variants/full-desktop.yaml Variant 'full-desktop': PASS Effective features (58): ...minimal-ci set plus dashboard, lsp-server, mcp-server, oslc-client, wasm-adapter, feat-oslc, feat-wasm, and all 14 init presets (aspice, stpa-ai, cybersecurity, eu-ai-act, safety-case, do-178c, en-50128, iec-61508, iec-62304, iso-pas-8800, sotif, plus the three in minimal-ci). Notes from reading the code: * `rowan-yaml` cargo feature: default-on, with a `cfg(not(feature = "rowan-yaml"))` fallback path in rivet-core/src/db.rs — so the alternative group has two real arms, not one. * `aadl` cargo feature: default-on. Modelled as a mandatory (always-present) adapter since no real build disables it — not as an optional-feature toggle. * `oslc` and `wasm`: off-by-default cargo features, correctly modelled as optional with implies-constraints from the adapters. * `lsp-server`, `dashboard`, `mcp-server` are *not* behind cargo features — they're always compiled in today. The variance is runtime/deployment, not compile-time. Flagged this as a surprising mismatch with the v0.4.0 narrative (where LSP/MCP are described as optional deployment surfaces): they are, but only in the sense of "whether you launch that process", not "whether the code is in the binary". * The rowan YAML parser rejects multi-line `#` comments between mapping entries at the same indent (`expected mapping key, found Some(Comment)`). Worked around by keeping single-line section comments in feature-model.yaml; flagging this as a latent parser bug worth a follow-up issue. Refs: #128 * feat(audit): v0.4.0 artifacts, retroactive trailer map, Verus hard gate Addresses three gaps found in the post-v0.4.0 dogfooding audit. **v0.4.0 shipped-work artifacts** — `artifacts/v040-features.yaml` was last touched 2026-04-12 and describes variant/PLE work (FEAT-106..114), not the verification pyramid that actually shipped on 2026-04-19. New file `artifacts/v040-verification.yaml` authors 4 design decisions (DD-052 four-layer verification pyramid, DD-053 suffix-based yaml-section matching, DD-054 non-blocking framing for formal CI jobs, DD-055 cfg-gate platform syscalls), 8 features (FEAT-115..122 covering Kani 27-harness expansion, differential YAML tests, operation-sequence proptest, STPA-Sec suite, suffix-based UCA extraction, nested control-action extraction, Zola export, Windows support), and 1 requirement (REQ-060 cross-platform binaries). Counts were verified against the actual codebase — 27 `#[kani::proof]` attrs in proofs.rs, 6 differential tests, 16 STPA-Sec tests. **Retroactive trailer map** — extended `AGENTS.md` with three more legacy orphans (51f2054 #126, f958a7e, 75521b8 #44), a new v0.4.0 PR-level section for #150/#151/#152/#153, and an honest "genuinely-unmappable" section calling out `ca97dd9f` (#95) whose `SC-EMBED-*` trailers point to artifacts that were never authored. **Verus Proofs → hard gate** — rules_verus PR #21 (merged as 5bc96f39) fixes the hub-repo's ambiguous `:all` alias by emitting proper `toolchain()` wrappers per platform. Updates the git_override pin from e2c1600a (Feb 2026, broken) to 5bc96f39 and removes `continue-on-error: true` from the Verus job.

Prefixed with `_artifact`. - **Rocq**: Schema.v / Validation.v opened `string_scope` but used `++` on `Store` (a list). Rocq 9.0.1 parses `++` in string_scope as `String.append`, so `s ++ [a]` failed with "s has type Store while expected string". Added `Open Scope list_scope.` after the string open so list concatenation takes precedence. Neither file uses string `++` so the scope swap is safe. - **Verus**: unblocked the `:all` alias bug via upstream rules_verus PR (5bc96f39), but hit a deeper upstream issue — rules_rust 0.56.0 references `CcInfo` which has been removed from current Bazel. Needs a rules_rust bump inside rules_verus before Verus can be a hard gate. Reverted to `continue-on-error: true` with a pointer comment so this is honestly signposted rather than silently advertised as shipped. Mutation Testing rivet-cli passed on the first run. rivet-core still running. /graph budget works in CI (included in the same PR). Implements: REQ-030 * fix(rocq): drop Open Scope string_scope, tag string literals The `Open Scope string_scope.` at the top of Schema.v / Validation.v shadowed `length` (String.length vs List.length) and `++` (String.append vs List.app), breaking every Store operation once the proofs got compiled under Rocq 9.0.1. Neither file actually uses infix string operators — all string literals are either passed to `String.eqb` or constructed with explicit `%string` tags. Drop the scope open; tag the one remaining bare literal `"broken-link"` in Validation.v:120 with `%string`. Explanatory comment in both files so a future reader doesn't reopen string_scope and re-break this. * fix(rocq): fully qualify List.length in proofs With `Require Import Coq.Strings.String` after `Coq.Lists.List`, the bare identifier `length` resolves to `String.length` (the latest import wins), so `length s` with `s : Store` fails to typecheck. Qualify every `length` call against a list as `List.length` so name resolution cannot drift. Five call sites across Schema.v / Validation.v. * fix(rocq): apply -> eapply reach_direct for constructor with implicit lk `reach_direct` has a forall-bound `lk : LinkKind` that isn't surfaced in the goal after `apply`. Rocq 9.0.1 refuses the implicit instantiation that older versions allowed, fails with "Unable to find an instance for the variable lk". Using `eapply` creates a metavariable that unifies when the inner `exact Hl1_kind` step substitutes the real link kind. * fix(rocq): admit vmodel_chain_two_steps honestly (real proof gap) The `apply reach_direct` + `eapply reach_direct` routes both fail under Rocq 9.0.1 because the proof has an actual hole: `t1` (the link target artifact introduced by destructing `artifact_satisfies_rule`) is not the same as `a2` (the caller-supplied intermediate). The goal after the link-wiring step reduces to `link_target l1 = art_id a2`, but we only have `art_id t1 = link_target l1` — nothing ties `t1` to `a2`. Rather than write around the gap with tactics that wouldn't hold, mark the theorem `Admitted.` with an explicit comment describing what the correct strengthening would look like. All other theorems in Schema.v / Validation.v remain Qed'd. This lets the Rocq hard gate actually compile and enforce the proofs we DO have, rather than hiding a stale semantic break behind a tactic that just happened to typecheck on older Rocq. * fix(ci): honest gate status after first real run The first hard-gate run surfaced issues deeper than one-line fixes. This commit restores honesty rather than hiding them: **Hard gates that stay on:** - Kani compile errors (`store: None`, `_artifact`) — fixed, but see below. - Rocq `Open Scope list_scope.` + `List.length` qualification + `eapply reach_direct` — applied. - Mutation Testing (rivet-cli): 0 surviving mutants, hard gate. **Jobs moved back to continue-on-error with TODOs:** - **Kani**: 27-harness suite exceeded the 30-min CI budget and got cancelled. Bumped timeout to 45 min and left continue-on-error on until we scope the PR-sized subset vs nightly full suite. - **Rocq**: Rocq 9.0.1 is stricter than the version the proofs were written against. Fixed three classes of errors; a fourth (`No such contradiction` in a destructure) remains unfixed. Also `vmodel_chain_two_steps` has a genuine proof gap (link target t1 ≠ caller's a2 without an extra hypothesis) and is now `Admitted.` with an explicit note. Needs a systematic port pass before hard-gating. - **Mutation Testing (rivet-core)**: 3677 mutants, real surviving ones in `collect_yaml_files` / `import_with_schema` (lib.rs:80,241,268) and `bazel.rs::lex` (delete match arm `b'\r'`). Those are actual test coverage gaps. Hard-gating rivet-core means writing tests to kill every one of them first; scoping that out of this PR. rivet-cli mutation stays hard-gated per above. - **Verus**: still blocked on rules_rust 0.56 `CcInfo` removal upstream. The goal of "real hard gates" was to stop advertising verification that never ran green. Three checkpoints are now genuine (rivet-cli mutations, Kani compile-clean once unblocked, Rocq compile-clean once ported). The rest have explicit follow-up notes in ci.yml pointing at what needs to happen before they flip. * ci(verus): flip to hard gate; bump rules_verus pin past CcInfo fix The Verus job was marked continue-on-error because rules_verus's minimum rules_rust (0.56.0) used the Bazel built-in `CcInfo` symbol that current Bazel has removed, so the module failed to load. pulseengine/rules_verus@fc7b636 bumps the floor to 0.58.0 — the release where CcInfo is loaded from @rules_cc//cc/common:cc_info.bzl instead. Bumping our pin past that commit unblocks the load and lets the verus job run as a real gate. The same pin range (5e2b7c6) also picks up three correctness fixes in verus-strip: backtick-escaped `verus!` in doc comments no longer truncates output, `pub exec const` strips the `exec` keyword, and content after the `verus!{}` block is preserved. Trace: skip * fix(bazel): expose verus_specs.rs via rivet-core/src/BUILD.bazel //verus:rivet_specs_verify references `//rivet-core/src:verus_specs.rs` as a Bazel label, but rivet-core/src was not a Bazel package, so `bazel test` failed analysis with: ERROR: no such package 'rivet-core/src': BUILD file not found Adds a minimal BUILD.bazel that marks the directory as a package and exports the verus specs file. The crate itself is still built via cargo — this file exists only so the Bazel-side Verus targets can address the spec source. Trace: skip * refactor(bazel): unify repo into a single bzlmod workspace verus/ and proofs/rocq/ each had their own MODULE.bazel, which made every Bazel label relative to those subdirectories. That broke //verus:rivet_specs_verify's attempt to reference //rivet-core/src:verus_specs.rs — the label resolved against the verus/ workspace root and demanded a `verus/rivet-core/src` directory that doesn't exist, yielding: ERROR: no such package 'rivet-core/src': BUILD file not found Root cause was architectural. Consolidate into one workspace at the repo root so cross-directory Bazel references work: - New top-level `MODULE.bazel` merges the two previous module declarations (rules_verus + rules_rocq_rust + rules_nixpkgs_core, same commit pins and same toolchain registrations). - New top-level `BUILD.bazel` as a minimal package marker. - Deleted `verus/MODULE.bazel` and `proofs/rocq/MODULE.bazel`. - CI: run `bazel test //verus:rivet_specs_verify` and `bazel test //proofs/rocq:rivet_metamodel_test` from the repo root, not `working-directory: verus|proofs/rocq`. The Rust crates are still built via cargo. Bazel in this repo is scoped to the formal-verification targets only. With the unified workspace, //verus:rivet_specs_verify can now reach //rivet-core/src:verus_specs.rs which is the precondition for the Verus hard gate to do real work. Trace: skip * fix(ci): install Nix on Verus runner too Workspace consolidation (6771e6e) means root MODULE.bazel registers both Verus and Rocq toolchains. Bazel resolves every registered toolchain at analysis time regardless of which target is being built, so the Verus-only job now hits the Rocq toolchain extension, which requires rules_nixpkgs_core, which requires nix-build on PATH: ERROR: An error occurred during the fetch of repository 'rules_rocq_rust++rocq+rocq_toolchains': Platform is not supported: nix-build not found in PATH. Install Nix on the Verus runner too. Small cost (~30s) on a job that already takes 20 min, and it's the minimal fix — alternatives (split MODULE.bazel, or rules_nixpkgs_core fail_not_supported) either undo the consolidation or require upstream changes. Trace: skip * ci(verus): soft-gate again — toolchain works, specs fail Workspace hoist + Nix install fixed the plumbing: Verus now analyses //verus:rivet_specs_verify against //rivet-core/src:verus_specs.rs and invokes rust_verify. But the specs themselves fail verification in 0.1s — a real SMT proof obligation can't be discharged. That's spec-level work (audit which `requires`/`ensures` clauses are wrong) and doesn't belong in this CI-hard-gate PR. Soft-gate until the spec fixes land. Trace: skip
