In +both, the reviewed diff is benign; the payload lives one hop away. OSV/GHSA +classify new malware on the order of ~3 days (28-day NVD median), so advisory +gating alone misses the window. The exploitable invariant: a reference whose +resolution happens on the victim machine is neither reviewed nor pinned. + +Rulings (locked, no re-litigating): + +1. Recursion lives in the ENGINE, not the CLI. `evaluate_with_registry` gains + a threaded review context (depth, visited set, delivery chain, shared + registries); every entry point — CLI `review`/`install`/`ci`, MCP + `review_install` — inherits it with no surface-specific code. +2. Reference surfaces in v1: (a) npm manifest lifecycle scripts + (`preinstall`/`install`/`postinstall`/`prepare`) invoking a package + manager (`npm/npx/pnpm/yarn/bun` + `install/i/add/exec/x/dlx/run`) — the + Shai-Hulud/TanStack lane; (b) PKGBUILD npm/bun delivery — the existing + R23 scan, extended to yield the parsed spec; (c) wheel `.data/scripts` + and entry-point-adjacent payloads scanned statically for pip/npm + invocations. Entry points that reference the distribution's OWN modules + are not recursion triggers (they execute deferred, but reference nothing + installable; R02 already covers them). +3. Non-registry references (`git:`, URLs, `file:`) are NOT recursively + reviewed in v1 — resolving arbitrary git hosts is a new trust surface. + They keep their existing findings (R04 family) and the card discloses + that referenced non-registry installs were not reviewed. No silent gap. +4. New rules: `R24_LIFECYCLE_INSTALL_REF` (HIGH) for a package-manager + install invoked from an npm lifecycle script, with MEDIUM variants for an + unpinned spec (mutable payload) and an unresolvable spec; dynamic/ + unparseable specs (command substitution etc.) surface as MEDIUM + "unparseable install reference" — never guessed at. `R25_RECURSION_DEPTH` + (HIGH, fail closed: the cap is stated, never silent) and + `R26_RECURSION_CYCLE` (HIGH). Roll-up finding `R27_SECOND_ORDER` carries a + child finding that meets the policy threshold into the parent verdict. +5. R23 graduates Low → MEDIUM: with recursion covering what it points at, + the delivery line is a real second-order install signal; the INFO band + existed only because nobody resolved the reference. +6. Policy (`[recursion]` in blueline.toml): `max_depth` default 3, + `max_child_reviews` default 8 (bounds CI/fan-out cost; exceeding either + emits R25, fail closed), `child_block_band` default `"high"` — a child + finding at or above the band escalates the parent verdict; ambiguity + resolves to block. +7. Cache/memo: a session-scoped driver holds one registry instance per + ecosystem (today each `evaluate_package` call builds a fresh one) and a + bounded in-memory tarball memo keyed `(ecosystem, name, version)`, cleared + on overflow like the AUR `clone_cache`. The visited set is both cycle + detection and the no-re-review memo. Store schema UNTOUCHED. +8. Children are never approved, never marked clean; `record_verified` + evidence rows only. The parent decision decides; interactive approval + happens once, on the parent. +9. Verdict JSON grows `recursive: Vec` (skipped when empty) + where `ChildReview = { chain: Vec, name, version, ecosystem, band, + risk_score, findings }`. Per D7 the CLI card, CI report, and MCP + structuredVerdict all inherit it. The card renders the delivery chain + ("delivered via: pkgbase → npm:package@ver"). +10. `extract.rs` untouched (scanning happens post-extract on the extracted + root and manifest views).

R23 graduates to MEDIUM The review card renders each child review's delivery chain, band, and worst findings (bounded, never silent). R23_NPM_DELIVERY graduates from INFO now that recursion resolves what delivery lines point at, with the three benign-corpus electron fixtures pinned as true positives.

Hooks are +repo-committable config and themselves an attack vector — recipes must +live in USER-level settings, not the repo, and say so. + +Rulings (locked, no re-litigating): + +1. Primary surface: `blueline agent ` — no interactive prompt ever, + single-line JSON verdict on stdout (the D7 schema), deterministic exit + codes (0 approve/Low, 2 blocked/refused, 1 error), human hints on + stderr only. Approval is policy-bound: the verdict band decides, the + same blueline.toml thresholds/allowlists apply. +2. Second surface: `blueline agent gate` — the hook binding. Input: the + command line to police via `--command`, or hook stdin (Claude Code + PreToolUse JSON and Cursor beforeShellExecution JSON are both accepted; + the command string is extracted). Output via `--format claude|cursor| + plain` in each product's native decision shape; plain (default) uses + exit codes only. The command string is scanned with the SAME + install-reference scanner as reviews (install_ref::scan_line) — one + parser, one grammar, no second opinion to drift. Package operands are + reviewed via the recursive engine; bare installs (no operands) are + ALLOWED with a stderr note pointing at `blueline ci` (a bare install + pulls the manifest's deps — policed by CI, disclosed honestly). +3. Backstop: `blueline shim install + [--dir ]` (and `blueline shim uninstall`) writes bash shims into + a user-chosen dir. Shims extract specs from the invocation, run + `blueline agent` per spec, and exec the REAL package manager (absolute + path resolved at install time, PATH fallback excluding the shim dir) + only when every verdict is Low. Fail closed everywhere: blueline + missing, errored, or refusing ⇒ the install does not run. pip flags + that name non-registry sources (-r/-e/--constraint/--target/...) are + refused with a pointer to `blueline ci` rather than guessed at. + `yay/paru -S` with operands reviews each AUR spec; update runs without + operands pass through and are disclosed as a bypass in the docs. +4. The bypass list is documented on the card of truth (README): absolute + binary paths, `command npm`, `env -i`, direct npm-cli.js, npx resolving + from node_modules/.bin, PATH reordering, hook config tampering in + repo-committable settings. No security theater: the shim is + defense-in-depth for the terminal, hooks for the agent, CI for the + manifest — the campaign says so in writing. +5. Audit: every `agent` decision writes the existing audit_log with + `decided_by = "agent:"`; identity comes from process env + (CLAUDECODE/CLAUDE_CODE_ENTRYPOINT → claude-code, CURSOR_* → cursor, + CODEX_* → codex, else unknown-agent) and lands in `notes` (env names + only, never values — no telemetry beyond the local store, D8 holds). +6. Codex CLI has no hook process: the recipe is a Starlark `prefix_rule` + set to `prompt` for install verbs plus instructions to route installs + through `blueline agent` — stated as advisory in the docs, not sold as + enforcement. +7.

Surface veto-worthy decisions instead of +guessing. **Ask first** on any dependency or any change to `extract.rs` / +`store.rs`. + +## Campaign 1 — Recursive review (close the delivery loop) + +Today blueline reviews one release delta. Both documented attacks (TanStack +worm, Atomic Arch) delivered through a *second-order* install nobody reviewed. +Fix that. + +- Implement the deferred `R23_NPM_DELIVERY` follow-up from `TODO.md`: when a + review discovers an install reference, pipe that referenced spec through the + npm review engine rather than only naming it. +- **Generalize** into a recursive review pass: any install reference found in + a reviewed payload — npm lifecycle script invoking a package manager, + PKGBUILD `npm install`/`bun install` delivery, wheel entry points and + `.data/scripts` — triggers a recursive blueline review of the referenced + package, with: + - a depth cap (fail closed, stated on the card, never silent); + - cycle detection (A → B → A); + - re-use of the existing cache machinery so referenced packages are not + re-downloaded; + - roll-up of child findings into the parent verdict (a HIGH finding in a + referenced package must be able to BLOCK the parent — policy decides the + threshold, fail closed when ambiguous). +- The review card renders the delivery chain ("delivered via: pkgbase → + npm:package@ver"), the JSON verdict schema grows a recursive-findings field + (it is the single source of truth per D7 — CLI, CI, and MCP all get it). +- Rules R23 (npm delivery) and friends graduate from INFO to their earned + bands once recursive review covers what they point at. + +## Campaign 2 — Agent-native enforcement + +ARCHITECTURE.md marks the "invasive PATH shim" as secondary. Promote it: the +MCP `review_install` tool is what a well-behaved agent calls; the shim is what +makes bypass impossible. + +- Non-interactive `--agent` mode: policy-bound approval (no interactive + prompt), machine-readable verdict on stdout, exit codes CI and hooks can + branch on, and an audit-log entry that records the invoking agent context. +- PATH-shim routing: installable shims that route `npm`, `npx`, `pip`, + `cargo install`, and (where applicable) `yay`/`paru` invocations through + blueline before the real package manager runs. Every shim is fail closed: + if blueline errors or the policy cannot be resolved, the install does not + run. Document every known bypass honestly on the card/docs (e.g. direct + binary invocation, version flags that skip scripts) — no security theater. +- First-class integration recipes: Claude Code hook config, Cursor and Codex + CLI equivalents — copy-paste configs like the yay `AURPreInstall` recipe in + the README. +- Keep "no default telemetry" (D8): agent audit trails stay local unless the + user explicitly opts in. +- Rework cli to be slightly more simple for an external agent who may be using it. +## Campaign 3 — Recall / revocation index + +The one unchecked box in README and ROADMAP ("Revocation index and recall +API"), motivated by the TanStack-worm lag window in OSV. + +- Build it **local-first and self-hostable**: an index service (in-repo, + respecting the dependency rule) serving curated revocations; a client sync + path in blueline that folds index hits into the existing advisory/revocation + engine (`src/advisory.rs`) and the verdict as a BLOCK-class finding. +- Fail closed on sync failure that matters: a stale-beyond-threshold index is + disclosed on the card, and a policy flag can make staleness BLOCK. +- Seeding: blueline's own audit log (approvals, holds, blocks) can export + candidate revocations for human curation — the curation workflow is part of + this campaign, even if minimal. +- Hosted deployment, tokens, and any paid-tier gating (D6) are **out of scope + until the user approves** — the service must run end-to-end locally first. + +## Campaign 4 — Dogfood & distribution + +D9 says "we audit supply chains — we must eat our own dog food." Make it true. + +- Fill the gaps in `packages/` so the npm shim is genuinely installable; + verify `npx blueline` works from a cold environment. +- Ship the CLI for real distribution paths: crates.io publish config, Homebrew + formula, and blueline itself packaged for the AUR (reviewed by its own AUR + reviewer, of course). +- Gate blueline's own supply chain with blueline: run `blueline ci` against + this repo's `Cargo.lock` and `package-lock.json` on every PR, and review + every blueline dependency delta before release. +- Signed, provenance-attested release binaries per D9 (wire into + `release.yml`; npm publishing already uses `--provenance`). +- **Any external publish (npm, crates.io, AUR, Homebrew) requires explicit + user confirmation — run `--dry-run`/packaging checks first and present the + result.** Publishing is outward-facing; never auto-publish. +- Add as much dog-fooding as possible. + +## Per-slice loop (inside every campaign) + +A **slice** is one PR-shaped, reviewable unit from the campaign's brief +(e.g. Campaign 1 might be: slice 1 = install-reference detection + data +plumbing; slice 2 = recursive engine + caps/cycles; slice 3 = card/JSON/ +policy roll-up; slice 4 = corpus + fuzz targets). + +After **every** slice: + +1. Run the full CI gate; fix before proceeding. +2. Dispatch **subagents in parallel** (Agent tool, `Explore`/`general-purpose` + as appropriate) for three independent reviews: + - **Adversarial security reviewer:** walk every new parse/extract/verify + boundary as hostile input. Hunt for: anything executed or sourced that + should only be parsed, missing bounds/caps, silent truncation, unwrap on + untrusted data, shell injection in any subprocess invocation (argv-only, + never a shell), fail-open paths. + - **Test auditor (non-bloat):** tests must pin behavior and kill mutants — + no snapshot theater, no redundant fixtures, no tests that pass under + mutation. Flag BOTH gaps in coverage AND bloat; recommend deletions + where a test adds nothing. + - **Fresh-eyes code reviewer:** module boundaries vs ARCHITECTURE.md, + error surfacing with `{e:#}`, naming, dead code, comment discipline. +3. Fix every P1/P2 finding, then **re-dispatch the reviewers** on the fixed + diff. Repeat until clean. A slice is not done until reviewers pass it. +4. Add the CHANGELOG `[Unreleased]` entry and commit in small commits (3–4 + changes each). + +## After each campaign — use the thing (use-it skill) + +After each campaign passes review, use the `use-it` skill to actually use +what you built, end to end, in this environment. Reading the code is not +using it. + +1. **Recursive review:** build an adversarial fixture registry where package + A's lifecycle script references package B whose delta contains a backdoored + script — the real CLI must surface the recursive finding and BLOCK without + executing anything. Also run a real `blueline --ecosystem aur review` + against a PKGBUILD with npm delivery and confirm the chain renders. +2. **Agent enforcement:** install the shim in a sandboxed project, run a real + `npm install` through it (approved version passes, unapproved blocks, audit + trail written), and wire a Claude Code hook config and trigger it. +3. **Recall index:** run the service locally, seed one human-verified + revocation, query it from the client, and verify: hit → BLOCK, stale index + → disclosed, service down → fail-closed behavior per the brief. +4. **Distribution:** install the artifact through the real channel in a clean + environment (or dry-run equivalent pending publish approval) and re-run the + Campaign 1–3 verifications against the distributed binary, not the local + build.
