Sync with NVIDIA/SkillSpector 2.12.0

Merges upstream/main at 5edc347 into the fork: 805 commits, 192 on upstream's mainline, version
2.9.6 → 2.12.0. Eighteen files conflicted. After this merge
git rev-list --count $(git merge-base upstream/main HEAD)..upstream/main is 0.

Important

Merge this with a merge commit. Do not squash. A squash keeps the tree and drops the second
parent, so the merge-base does not advance and the next sync re-measures all 805 commits as drift.
Every other PR in this repository is squashed on purpose; this is the one exception.

Warning

Every committed Behavior Snapshot moved, and nine are new. In this repository a snapshot diff
normally means a regression. Here it is the expected result of an upstream merge, and the ledger
below names the upstream commit behind each delta.

Closes #136.

What a user of the fork will notice

These are upstream's behaviors, taken as they are. Each one replaces something the fork had
documented or tested differently.

Change	Before	After	Upstream commit
`--recursive` threshold	needed two immediate child skills	engages on one; only zero falls through	`ed787e9` (NVIDIA#429)
`--recursive -f sarif` / `-f markdown` with no `--output`	wrote nothing to stdout	prints the report, like `json` and `terminal`	`20fdba7` (NVIDIA#565) for SARIF, `fcfbcd8` (NVIDIA#576) for Markdown
A failing child scan under `--recursive`	the exception text in the report and on stderr	one fixed sentence, so no path or secret leaks	`fcfbcd8` (NVIDIA#576)
`skillspector baseline`	fingerprinted the reported findings	refuses a failed scan, warns on a partial one, fingerprints every occurrence	`e5ceb61` (NVIDIA#637), `9108009` (NVIDIA#657)
Transitive resolver failure	exit `0`	exit `2`	`fcfbcd8` (NVIDIA#576)
`codex_cli` provider	usable	registered but disabled	`d3b8590` (NVIDIA#737)
Combined JSON (`--recursive` and `--repo-scan`)	—	gains `risk_severity` and `skills_output_omitted`	`fcfbcd8` (NVIDIA#576)

Two resolutions that are the fork's choice, not upstream's

A reviewer should look at these two first. Both are reversible in cli.py alone.

Stream routing stays the fork's. Upstream now routes progress lines by format: stdout for
--format terminal or when --output is given, stderr otherwise. The fork's documented contract
is stricter — the report owns stdout, everything else goes to stderr in every format — and it
keeps stdout clean in every case upstream's rule protects. I kept the fork's rule by binding
upstream's progress_console to the fork's stderr console. Cost: one upstream test now reads
result.stdout instead of the folded result.output.
One builder for the combined JSON. Upstream builds the --recursive object inline; the fork
builds it through _combined_json_report, shared with --repo-scan. I kept the shared builder
and extended it with upstream's two new keys, so both discovery modes still answer in one shape.
Verified with a real scan: both modes emit the same fifteen keys in the same order.

Where upstream's zero-children warning and the fork's fall-through advisory now describe the same
case, both are printed, upstream's first. That keeps upstream's own tests unmodified.

Conflict resolution

File	Kept
`nodes/analyzers/__init__.py`	Upstream's whole. Its discovered registry (`837d100`, #74) registers the four fork Analyzers through the `ANALYZER_ID` and `node` they already expose. The fork no longer edits this file.
`cli.py`	Upstream's logic; `--repo-scan`, `--spec-checks` and the fall-through advisory re-applied on top. `spec_checks` threads through upstream's new `_run_graph_scan_for_source` with `partial`, the way upstream binds its own optional arguments.
`meta_analyzer.py`, `llm_analyzer_base.py`, `build_context.py`, `report.py`, `state.py`, `static_yara.py`, `pattern_defaults.py`, `mcp_server.py`	Disjoint hunks; both sides kept.
`README.md`	Fork sections above the marker. Upstream's text below it; pattern counts recounted from the table rows (95 → 97: `SC10`, `EA5`).
`pyproject.toml`, `uv.lock`	Upstream's version and three new dependencies plus the fork's; lockfile regenerated with `uv lock`, not merged.
`THIRD_PARTY_NOTICES.md`	Both sides, plus entries for `pywhatwgurl` and `regex` (see Open questions).
`.gitignore`, test files	Both sides.

Fork tests rewritten because upstream changed the behavior they pinned: the one-child threshold
(two tests), recursive SARIF/Markdown on stdout, the sanitized child error (two tests), two
LangChain4j AR1 counts, and the ledger-exception expectation. Three upstream tests were adapted to
fork contracts: _parse_manifest returning a tuple, the strict AnalyzerStatus constructor, and
result.stdout.

Both vocabulary guards gained paths and deny as homonyms: upstream's OpenCode provider and its
bundled-permission Analyzer write both as their own configuration keys.

Snapshot ledger

In every one of the 38 existing snapshots

Delta	Upstream commit
New `bundled_execution_surface` row in `analyzer_statuses`	`ed787e9` (NVIDIA#429)
`start_column` / `end_column` on findings, `end_line` populated, SARIF `columnKind` and region columns	`d0b446f` (NVIDIA#409), `0f176d5` (NVIDIA#584)
SARIF `security-severity` on rules and results	`00c2d99` (NVIDIA#621)
`match_fingerprint` values	`d0b446f` (NVIDIA#409)

No existing analyzer's status, reason or planned work changed, and the order of analyzer_statuses
is unchanged. I checked this by analyzer id, not by position.

Finding-level deltas

Snapshot	Delta	Upstream commit
`langchain4j_shell_skill`	+3 `AR1` (a second distinct match on three lines)	`d0b446f` (NVIDIA#409), `7805bb9` (NVIDIA#462)
`langchain4j_tool_mode`	+1 `AR1`, same cause; risk 54 → 63	same
`malicious_skill`	+1 `P5` at line 38, same cause; risk 93 → 100	same
`sdi/sdi2_inappropriate`	−1 `PE2` on `chmod 644`; risk 31 → 20, `CAUTION` → `SAFE`	`2cd8e87` (NVIDIA#678)
`sqp/sqp1_clean`	`reference_unresolved` ledger exception gone; `is_complete` false → true	`f161b70` (NVIDIA#451)
MCP fixtures (`LP1`–`LP4`)	`finding` and `pattern` populated; `LP3` remediation reworded	`d051d28` (NVIDIA#641), `05d7882` (NVIDIA#685)
One `TM1` finding	`context` / `code_snippet` window	`dd95368` (NVIDIA#578)

The AR1 and P5 additions are not new detections. Each line already produced one finding;
upstream stopped folding two distinct matches on one line into the first.

Nine new snapshots

Upstream added nine fixture skills beside the fixes they regression-test. They join the corpus
(38 → 47): as3_self_reference, pe3_bare_keyring, tp4_markdown_fenced_code,
sqp/sqp2_tool_catalog_clean, sqp/sqp2_tool_descriptive_step, sqp/sqp2_tool_instructed,
sqp/sqp3_forced_language, sqp/sqp3_plain_english_clean, sqp/sqp3_plain_english_override.

Limit of this ledger

104 upstream commits touch analyzer, context, state or report code. Most are narrow false-positive
fixes with no fixture in this corpus, so they move nothing here. I confirmed the reverse direction
only for the commits that should reach fork fixtures: NVIDIA#409/NVIDIA#462 (the AR1 deltas above), NVIDIA#584
(columns on every L4J-* and DA-* finding) and NVIDIA#429 (the new status row in every fork fixture).

Verification

Run on the merge commit's tree:

make test-unit: 14635 passed, 1 failed. The one failure was the corpus-count literal (38 → 47);
after fixing it tests/behavior and the touched file pass (644 passed).
make lint, make format-check: clean.
make update-snapshots: leaves the tree clean.
CLI stream tests re-run under a long TMPDIR: 147 passed.
Real scans of a two-skill directory with --recursive in all four formats: report on stdout,
summary table on stderr.

Not verified locally: CI's new test-opencode job. It needs Node 22.20; this machine has
22.11, which lacks registerHooks. The files it runs are byte-identical to upstream's.

Found while syncing, and fixed here

The weekly drift workflow had never run. .github/workflows/upstream-drift.yml carried a
comment inside a run: block that spelled the Actions expression syntax with nothing between the
braces. GitHub expands expressions in comments too and rejects an empty one, so the file was
invalid: 26 pushes recorded a failed run with zero jobs, and the schedule never fired. That is why
no Upstream drift: issue existed when this sync started 805 commits behind. The comment is
reworded and a test now fails on an empty expression. The first scheduled run can only happen once
this is on main; workflow_dispatch from the Actions tab confirms it sooner.

A path-scoped rule was steering work against the code. .claude/rules/allowed-tools-separator.md
said allowed-tools is split on commas only and must not be fixed. Upstream 1b87593 (NVIDIA#330) made
both parsers accept the space-separated form. The rule, the design document and the README now say
the separator is closed, and keep the half that is still true: scoped syntax such as
Bash(git:*) maps to no capability.

Also corrected: make test-provider accepts gemini; the analyzers rule now says upstream's
registration walkthrough is stale; CLAUDE.md names the Node extension tests that neither pytest
nor make runs.

License audit, and what is still open

/license-audit was run on this branch. 369 header-carrying files: 63 fork-authored, 35
inherited and modified, 271 inherited and untouched. All four set-membership checks are empty,
LICENSE is identical to upstream's, and upstream ships no NOTICE. 116 files lack the Apache
boilerplate paragraph; every one is upstream's own omission and was left alone.
regex is Apache-2.0 AND CNRI-Python. Its LICENSE.txt names the CNRI license without
carrying it, so the maintainer chose to reproduce the text in THIRD_PARTY_NOTICES.md, taken
verbatim from SPDX.
The "five hashed fields" claim may now be six. Upstream's meta stage can also fill
code_snippet, which the fingerprint hashes. The claim appears in README.md,
docs/SUPPRESSION.md, docs/MULTI_FRAMEWORK_SKILL_ANALYSIS.md, CLAUDE.md and
suppression.py. It needs measuring under A v2 baseline fingerprint is bound to --no-llm: the meta stage rewrites five hashed Finding fields #124; this PR does not change it.
fix/report-writer-fidelity (JSON report drops a Finding's message, so every instance-specific rule message is invisible to JSON consumers #117, SARIF rule shortDescription is the first Finding's message, not a description of the rule #118, JSON and SARIF carry no signal that an advisory conformance finding was reported without being scored #125) needs a rebase after this lands. Upstream
rewrote parts of report.py under it.

A non-root owner can only assign groups it belongs to, so regenerating a baseline whose group it is not a member of (for example a file created under /tmp with group wheel and then moved) failed with EPERM and exited 2, where main rewrote the file in place. Fall back to the shared-writer path in that case: rewrite the already validated inode through its locked descriptor, keeping its owner, group, mode and ACLs. Move that path into a helper used by both callers.

A cooperating writer that atomically publishes between those steps made the other writer fail with "Baseline output changed while opening". The concurrent writer test hit this about once per 100 runs of 8 writers. Start validation again from lstat when the path changed before anything was written, up to two passes. The replacement gets the same regular file, writability, descriptor identity and lock checks. A path that keeps changing still fails closed, and nothing is written to an unvalidated inode.

A window for a call whose direct candidate was folded into an identical same-line call still reports that call. - A call-anchored window for a longer true-prefixed name (`true_value`) used its raw text as identity, so the raw and normalized security views of one call did not collapse, and reconciliation then moved both to the call. The window now takes its identity from the normalized view text, as the direct owner already does.

The later source-decoding pass then decoded it correctly, but the artifact stayed FAILED with a fatal event and 0% coverage. Waive the generic UTF-8 rejection when the bytes classify as Python and decode under their declared encoding; an unknown codec or bytes invalid for the declared codec remain fatal, and format checks (BOMs, archives, NUL density) are unchanged.

…sions-20261007 fix(pi): require confirmation for external scan inputs

…content-cache fix(suppression): separate local and transitive content caches

Merges upstream/main at 5edc347: 805 commits, 192 on the mainline, taking the version from 2.9.6 to 2.12.0. Eighteen files conflicted. Resolution, by whose intent was kept: - nodes/analyzers/__init__.py: upstream's whole. Its discovered registry (837d100) picks up the four fork Analyzers through the ANALYZER_ID and node they already expose, so the fork no longer edits this file. - cli.py: upstream's logic, with the fork's extensions re-applied on top (--repo-scan, --spec-checks, the fall-through advisory). Two decisions are the fork's and are stated in the pull request: every non-report line stays on stderr in every format, where upstream routes by format and --output; and both discovery modes keep building their combined JSON through one helper, which now carries upstream's risk_severity and skills_output_omitted. - baseline command, recursive error text, the one-child --recursive threshold, exit 2 on a transitive resolver failure: upstream's. - meta_analyzer.py, llm_analyzer_base.py, build_context.py, report.py, state.py, static_yara.py, pattern_defaults.py: disjoint hunks, both kept. - README.md: the fork's sections above the marker; upstream's text below it, with the pattern counts recounted from the tables (97). - pyproject.toml: upstream's version and dependencies plus the fork's; uv.lock regenerated rather than merged. THIRD_PARTY_NOTICES.md gains pywhatwgurl and regex, which upstream declares without an entry. Both were read from the installed dist-info (pywhatwgurl 0.1.1, regex 2026.5.9), each inside its declared pin. Every committed Behavior Snapshot moved, and nine are new. The pull request body carries the ledger that attributes each delta to an upstream commit.

The entry written during the 2.12.0 sync said the CNRI-Python terms ship in the distribution's own LICENSE.txt. They do not: that file names "CNRI's Python 1.6 license" on its second line and then carries the Apache-2.0 text alone. Read from the installed regex 2026.5.9 dist-info, which is the version pyproject.toml pins. Whether the CNRI text has to be reproduced here is left open in the pull request; this only stops the entry from claiming it is somewhere it is not.

regex is Apache-2.0 AND CNRI-Python, and the notices file reproduces the text of every other license it cites. Its own LICENSE.txt names CNRI's Python 1.6 license without carrying it, so the text is taken from SPDX (https://spdx.org/licenses/CNRI-Python.json, licenseText, verbatim and unwrapped as published) rather than from the installed dist-info, which has nothing to read it from. The maintainer chose to reproduce it; the audit had left it as an open question.

The path-scoped rule for build_context.py and mcp_least_privilege.py told a reader that allowed-tools is split on commas only and must not be fixed. Upstream 1b87593 (NVIDIA#330) made both parsers accept the space-separated form, and the 2.12.0 sync took it, so the rule was steering work against the code. Measured: "Read Write Bash" now derives file_read, file_write and shell. The rule keeps the half that is still true -- scoped syntax such as Bash(git:*) maps to no capability -- and the design document and README say the separator is closed rather than deliberately unfixed. Riding along, each exposed by the same sync: - test-provider accepts gemini; CLAUDE.md and the tests rule listed three. - The analyzers rule called DEVELOPMENT.md's registration steps an omission. They are upstream text that contradicts the discovered registry, and the rule now says which side wins. - CLAUDE.md names the Node extension tests, which neither pytest nor make runs, and the Pi extension rule also loads for .opencode/tools.

A comment inside the measurement step's run block named the Actions expression syntax literally, with nothing between the braces. GitHub expands expressions in comments too and rejects an empty one, so the whole file was invalid: every push recorded a failed run with zero jobs (26 of them, back to the commit that added the workflow) and the weekly schedule never fired once. That is why no "Upstream drift:" issue existed when this sync started 805 commits behind. The file is valid YAML, so nothing local noticed; the new test fails on the old comment and passes on the reworded one.

PR #142 was squashed, so main carries the 2.12.0 sync's tree with a single parent and the merge-base never advanced: step 1 of the sync measured 805 commits of drift on a tree that already contains them. This merge uses the ours strategy against upstream 5edc347, the commit the sync merged. It changes no file -- the tree is identical to d7a593a -- and only records the second parent, which takes the measured drift to zero.

) * docs(claude): move single-scope guidance out of the root CLAUDE.md The root file was 277 lines against a 200-line limit, and about a third of its Applied Learning bullets apply to one file pattern each while loading in every session. - Thirty-six bullets move to path-scoped rules, unchanged: the snapshot and fixture ones to a new behavior-gate rule, the vocabulary guard, tree-sitter and detection ones to a new framework-parsers rule, and five CLI and fake traps into the existing tests rule. - Four bullets are deleted because a rule already states them: the fingerprint invariant, the meta stage's rewritten fields, the per-skill baseline, and the discovered analyzer registry. - Four clusters of near-duplicates become one bullet each: gh body edits, CRLF noise, Ticket PR checks, and mutation testing. The three corpus-count bullets become one line in the behavior-gate rule. - The bullet saying no test covers the vocabulary_sweep role maps was wrong; contrib/vocabulary_sweep/tests/test_readers.py does, outside make test. - The Spec execution workflow moves to docs/agents/spec-workflow.md, the drift schedule's two human steps move into the upstream-sync skill, and Code search shrinks to what the user's global instructions do not already say. The root is now 186 lines. No instruction was dropped: every original bullet is present verbatim in the root or a rule, or is one of the merges and deletions listed above. Signed-off-by: Rodrigo França <20980109+rodrigorjsf@users.noreply.github.com> * docs(sync): repair a squashed sync against the commit it merged The upstream-sync skill and an Applied Learning bullet both gave the repair as 'git merge -s ours upstream/main'. That is right only while upstream has not moved. Once it has, the ours merge records commits nobody integrated as already merged, and the next sync skips them without a conflict to reveal it. The command now names the synced commit, the verification says what the drift count should be when upstream has moved, and the section records how the repair lands: a fast-forward push the maintainer approves, since a pull request goes back through the buttons that removed the parent. PR #142 was squashed despite the warning at the top of its body, which is the second time.
