…port) Public port of the private v1 hardening rounds (scope enforcement, orphan/quiz hardening, fan-out integrity), adapted to the kit's signed-receipt architecture. Bob stays the full 10-step pipeline; none of this weakens or replaces it. Run scope (mandatory, fail-closed): - BobRun.start requires a declared scope (the files/dirs/globs the run is FOR); run_bob generates content first and declares the test+impl files automatically. A no-scope start refuses; a scope stripped from run.json afterwards authorizes NOTHING at the gate. - The gate rejects staged files OUTSIDE the declared scope, so a run opened for module A cannot smuggle in edits to module B. Bob's own machinery (.agent-ultra/*) is exempt. - scope-add is the only expansion path: validated, appended to run.json, durably recorded in scope-log.jsonl (new CLI verb). - Enforcement infrastructure (.git/hooks, .agent-ultra) is rejected as a scope entry at start and at scope-add, always. - operator_unbounded=True is the explicit unbounded escape: Python-API parameter only (no CLI flag), rejected for a scoped start, loudly announced, durably logged. Lifecycle (no silent orphaning): - start(force=True) — CLI renamed --force -> --operator-force (BREAKING) — now leaves a durable abandonment record instead of silently superseding the unproven run. - New `bob abandon --operator-abandon [--reason]`: the only sanctioned explicit drop; refused without the flag; logs to .agent-ultra/bob/abandoned.jsonl + abandoned.json, loud on stderr. - The command broker classifies --operator-abandon/--operator-force/ --operator-unbounded as DANGEROUS, so a broker-mediated agent shell cannot auto-run the operator escapes. - (Already present, kept: a marker naming a deleted run dir is a tampering sentinel that fails the gate closed; quiz outcome 'passed' requires a captured operator response — self-graded quizzes never counted here.) Fan-out integrity: - cloned_fanout_error: a step-6/7 ultracode run whose completed agents ALL produced identical output (per-agent output_sha256 in the run receipt) is one review wearing N hats — the gate blocks it. Demo mode (--allow-mock) is exempt: the offline mock answers every agent identically by design, and mock evidence is only acceptable there. Also fixed in passing: test_edited_ultracode_receipt_breaks_fingerprint tampered the SHARED module-scoped ultracode receipt and never restored it (latent fixture pollution exposed by the new pass-expecting tests). Trust boundary unchanged and stated plainly: everything here is tamper-EVIDENT under a same-user attacker, not tamper-proof — the real boundary is the privilege-separated attestor (v2), out of scope. Tests: 184 passed (12 new: scope mandatory/infra/matching/staged in+out/expansion-logged/stripped-scope-fails-closed/unbounded-explicit/ no-CLI-flag; abandon operator-only+logged; CLI abandon flag required; broker denies operator flags; cloned fan-out). Doctor: 14 pass / 0 warn / 0 fail. Mock demo: gate PASSED, 9 receipts. Leak sweep: no private strings or paths in the diff. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…ic port) Public, stdlib-only port of the surgical lane. It NARROWS Bob, it never replaces it: every surgical check is a harder, smaller constraint than full mode, and anything code-shaped routes to the FULL gate. The lane (agent-ultra bob surgical "<task>" --files ...; run_surgical from Python; --mock for the offline demo): - a real two-lens review fan-out (accuracy + safety) as an ultracode workflow, fingerprint-pinned and workflow-name-bound exactly like steps 6/7 — a claimed-but-never-run review blocks; - an operator quiz: 'passed' requires the captured operator answer; an unanswered quiz is honestly 'skipped'; self-graded does not count; - its own fail-closed gate: HMAC receipt chain, staleness (an edit after the review blocks), declared-files-only staged set, and a 100-line / 256-KiB text-only diff budget (binary rejected, git errors fail closed). Entry criteria (objective, validated at start — bob/surgical.py): - inert types only: prose + known-inert dotfiles auto-qualify; structured config (yaml/json/toml/ini/cfg) is dual-use and needs the operator's explicit AGENT_ULTRA_SURGICAL_ALLOW_CONFIG=1 AND a clean denylist pass; - the denylist is executable-by-context files (CI workflows, git-hook managers, task runners, IaC/deploy, container files, package manifests, tool configs) matched by exact basename, basename prefix, path prefix, and SHAPE (<tool>.config.<ext>, .<tool>rc[.<ext>]) — never substring, so a doc ABOUT Dockerfiles stays a doc; - enforcement infrastructure (.git, .agent-ultra) is never surgical-editable; - a surgical run's scope IS its declared files; scope-add refuses risky/non-inert expansion; operator_unbounded is rejected outright. C1 mode-downgrade defense: run.json's mode field is a REQUEST the gate verifies, never a trusted assertion. gate_check routes to the surgical gate ONLY when the actual staged set independently qualifies (all inert, none denied, all declared) — flipping a run's mode to surgical with code staged gets the FULL gate and its full receipt-chain demands. A full-mode run never auto-downgrades, even with only inert files staged: surgical is opt-in at start. Tests: 202 passed (18 new in tests/test_bob_surgical.py: entry criteria incl. config opt-in + doc-about-tools non-matches; start rejections; scope binding; mock lane end-to-end; review-missing / self-graded-quiz / undeclared-risky-staged / post-review-staleness / oversized-diff blocks; forged-mode-routes-to-full; full-never- downgrades). Doctor: 14 pass / 0 warn / 0 fail. Live demo: bob surgical --mock gate PASSED, 2 receipts. Leak sweep: clean. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Added in ef8e56c: the surgical lane — public, stdlib-only port of the lightweight tier for inert doc/config edits.
202 tests passing (18 new) · doctor 14/14 · mock surgical demo gate PASSED · leak sweep clean. |
safe_rel judged absoluteness only under the NATIVE Path flavor, so on Linux "C:/Windows/x" has no drive/anchor and slipped through as a relative name (becoming a literal "C:" directory inside the workspace). Judge under BOTH flavors (native Path + PureWindowsPath): a model-authored Windows-absolute name is rejected everywhere. Fixes the ubuntu-latest CI legs, which have been red on main since the bob pipeline landed (test_safe_rel_rejects_absolute_and_traversal only passed on Windows runners). 202 tests pass locally.

Path Traversal (CWE-22): Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Reachability: External · Exploitability: Moderate
Validate declared surgical files at start. Reject each entry unless it resolves to an existing regular file inside the workspace, then store the validated relative paths in meta["surgical_files"]. Raw ../ entries reach _excerpt and can expose out-of-workspace content; missing entries reach sha256_file and raise an unhandled FileNotFoundError during run.write.
