Same enforcement model as the local hook, but unbypassable per PR. +Requires implementing the `--changed-vs ` mode (small extension of +`--staged`; same awk parser, different diff command). + +**Stage 3 (optional):** Either (a) clean the existing violations and add a +full-repo audit as a CI gate, or (b) snapshot a baseline file +(`scripts/.allowed-domains-baseline`) and run the full-repo audit with +baseline subtraction. Stage 3 is not committed-to in this design; the +decision can be made after Stages 1 and 2 are stable. ## Open Questions From cb89715d4c545331919900fdd2d405666599436b Mon Sep 17 00:00:00 2001 From: Aram Grigoryan <132480+aram356@users.noreply.github.com> Date: Mon, 18 May 2026 13:12:20 -0700 Subject: [PATCH 03/57] Pivot check-domains spec to Rust + gitoxide - Implementation moves from bash + ripgrep + awk to a new ts CLI subcommand: ts lint domains [--staged | --changed-vs | ...] - Lives in crates/trusted-server-cli (hard dep on PR #669). - All git operations go through gitoxide (gix), no subprocess to git. Staged mode and --changed-vs mode use gix-diff blob hunks; full-repo walks the gix index; merge-base via gix-revision. - Hook installer is itself a ts install-hooks subcommand (uses gix to write .githooks/pre-commit and to set core.hooksPath), so no shell script in scripts/. - Standard regex crate (no fancy-regex): URL patterns rely on host character classes to bound the match rather than lookahead. - Tightened suppression marker regex to require start-of-line or whitespace before the comment introducer, closing the bypass route via URLs that literally contain allow-domain in the path. - Tests use gix::init for temp repos; verifies the binary works under env -i PATH= to prove no git binary is required. - Trade-offs updated: new top-level gix dependency, no shell. Addresses third-review feedback findings 1, 5; supersedes earlier bash design. --- .../specs/2026-05-18-check-domains-design.md | 992 +++++++++++++----- 1 file changed, 732 insertions(+), 260 deletions(-) diff --git a/docs/superpowers/specs/2026-05-18-check-domains-design.md b/docs/superpowers/specs/2026-05-18-check-domains-design.md index 9ef320a9..63e1b657 100644 --- a/docs/superpowers/specs/2026-05-18-check-domains-design.md +++ b/docs/superpowers/specs/2026-05-18-check-domains-design.md @@ -1,109 +1,226 @@ -# `check-domains` Pre-Commit Linter — Design +# `ts lint domains` — Design **Date:** 2026-05-18 -**Status:** Draft (revised after first review) +**Status:** Draft (revised after third review — pivoted to Rust / `ts` CLI) ## Goal -Fail commits that introduce new URLs to non-allowlisted domains in source, -config, or documentation files.

The - subdomain rule means listing `privacy-center.org` would allow *every* - subdomain. -4. **Source-code reference hosts are allowed everywhere** (not split between - docs and code). Listing `github.com` allows it in `.rs`, `.md`, `.toml` - alike — splitting by file type is more complexity than it's worth. - -Changes to `ALLOWED_HOSTS` must be reviewed as part of the PR; reviewers -should verify the integration actually exists in the registry and the host -is the one being proxied/called. +1. **Vendor + integration**: the entry must correspond to a named + integration or a well-known reference/doc host. No personal + preferences, no test domains, no speculative entries. +2. **Justification in a `//`-comment** above the entry, naming the + integration and role. +3. **Narrowest workable host**: prefer the subdomain + (`api.privacy-center.org`) over the apex (`privacy-center.org`). +4. **Exact by default**: new vendor entries go into + `EXACT_HOSTS`. Move to `SUBDOMAIN_HOSTS` only when the vendor uses + multiple subdomains in real traffic and we accept trusting all of + them. +5. **Source-code reference hosts are allowed everywhere** (not split + between docs and code). + +Changes to either array must be reviewed as part of the PR. ### Per-Line Suppression -Some legitimate uses are not part of any integration — most notably security -tests that use `evil.com` and similar attacker-controlled placeholders -(real example: `crates/trusted-server-core/src/integrations/google_tag_manager.rs:838`). -To allow these without polluting the global allowlist, the linter -recognizes the literal token `allow-domain` anywhere on the same source -line: +Some legitimate uses are not part of any integration — most notably +security tests using attacker-controlled placeholders.

For each `Modified` / `Added` / `Renamed` change: + - Load the **old blob** from the HEAD tree (empty for additions). + - Load the **new blob** from the index. + - Run a **blob diff** using `gix-diff::blob` (which wraps + `imara-diff`, the Myers diff implementation `gix` uses + internally). + - Walk the resulting hunks; for each hunk's **post-image (new) line + range**, emit `DiffLine { path, line_no, content }` for each added + line. +6.

From 19c25ad8b32940bad1a7b4c655e3165bd546dcc7 Mon Sep 17 00:00:00 2001 From: Aram Grigoryan <132480+aram356@users.noreply.github.com> Date: Mon, 18 May 2026 13:25:07 -0700 Subject: [PATCH 04/57] Fix check-domains spec issues from fourth review - Unify suppression regex: both occurrences now use the bypass- resistant (?:^|\s) anchor. - Fix the jsdoc/block-comment test case so it actually matches the marker regex (marker must be adjacent to the comment introducer). - Add cdn.permutive.com to exact-match allowlist; add edge.permutive.app to subdomain-permitting allowlist (Permutive formats {org}.edge.permutive.app at runtime). - Drop .md from scanned extensions to avoid doc-host noise (docs.github.com, www.fastly.com, manage.fastly.com, vitepress.dev, keepachangelog.com, semver.org, grafana.com, docs.prebid.org all appear in real markdown files). Doc-link allowlist still applies to /// comments in .rs and # comments in .toml. - Reframe *-lock.json exclusion as a supply-chain trade-off rather than dependency noise. - Pre-commit hook now embeds the absolute path of the ts binary (resolved via std::env::current_exe at install time) instead of relying on PATH, fixing GUI git-tool fragility. - ts install-hooks now refuses to overwrite an unmanaged pre-commit hook; --force backs up and replaces. Managed hooks carry a '# ts-install-hooks: managed' marker for detection. - Tighten gix Cargo features (drop the worktree-mutation placeholder); document that config read/write is part of gix's default repository API surface. - Mark the gix index-vs-tree / tree-vs-tree / blob-diff helper APIs as prototype-required, with explicit list of conceptual operations the implementation commits to. Real entry points pinned during implementation pass. - Full-repo audit explicitly documented as scanning working-tree content (not committed state); --at deferred as Open Question. - Explicit-path mode now honours the extension filter (skips with stderr warning); --force-scan deferred as Open Question. - Defer exit-code wiring to whatever convention PR #669 establishes for the trusted-server-cli crate. - Expanded Open Questions with: gix API entry points, gix version pin, install-hooks clobber detection, --force-scan, --at . --- .../specs/2026-05-18-check-domains-design.md | 373 ++++++++++++++---- 1 file changed, 287 insertions(+), 86 deletions(-) diff --git a/docs/superpowers/specs/2026-05-18-check-domains-design.md b/docs/superpowers/specs/2026-05-18-check-domains-design.md index 63e1b657..cd8c5eb2 100644 --- a/docs/superpowers/specs/2026-05-18-check-domains-design.md +++ b/docs/superpowers/specs/2026-05-18-check-domains-design.md @@ -57,12 +57,12 @@ ts lint domains [--staged | --changed-vs | ...] Modes (mutually exclusive): -| Invocation | Behavior | -|---|---| -| `ts lint domains` | Full-repo audit.

Instead: - Markdown files are scanned; fenced code blocks are scanned too, matching the user's policy decision (config snippets and shell examples are exactly where accidental real hosts can land). - Introduce a third allowlist array REFERENCE_HOSTS for well-known documentation and specification sources (github.com, docs.rs, developer.fastly.com, iabtechlab.com, in-toto.io, etc.), curated from the actual .md files in the repo. - Extend the IANA reserved-TLD rule to cover all four RFC 2606 TLDs: .example, .test, .invalid, .localhost. - Add example.net and example.org to SUBDOMAIN_HOSTS (assets.example.net appears in real docs; both are RFC 2606 reserved). - Tighter allowlist maintenance policy with separate bars for the three arrays. - Add 9 Markdown-specific test cases: allowed reference link, disallowed link target, autolink form, HTML-comment suppression, multiple links on one line, fenced-code-block scanning (both disallowed and allowed), reference-list syntax, image link. - Renumber environment cases (35-38 -> 44-47). Full-repo audit remains diagnostic-only in Stage 1 — existing docs contain many violations that will be cleaned/suppressed incrementally. --- .../specs/2026-05-18-check-domains-design.md | 215 +++++++++++++----- 1 file changed, 157 insertions(+), 58 deletions(-) diff --git a/docs/superpowers/specs/2026-05-18-check-domains-design.md b/docs/superpowers/specs/2026-05-18-check-domains-design.md index 4e6be1ff..b1f8857c 100644 --- a/docs/superpowers/specs/2026-05-18-check-domains-design.md +++ b/docs/superpowers/specs/2026-05-18-check-domains-design.md @@ -142,41 +142,76 @@ No changes to `trusted-server-core` or `trusted-server-adapter-fastly`. ## Allowlist (Rust constants) -Two arrays as `const &[&str]` at module top of `dev/lint/domains.rs`. +Three arrays as `const &[&str]` at module top of `dev/lint/domains.rs`: +`EXACT_HOSTS` (integration proxies + loopback), `SUBDOMAIN_HOSTS` +(allow `*.host`), and `REFERENCE_HOSTS` (well-known doc/spec +sources, exact-match, allowed everywhere).

Policy: prefer rewriting illustrative placeholders to RFC 2606 reserved names; add legitimate integration/vendor hosts to allowlists; suppress per-line only for true one-offs. - Soften the REFERENCE_HOSTS curation claim — seed list, expected incomplete; final list driven by Stage 1 cleanup output. - Document policy on multi-line fenced-block suppression: rewrite to reserved hosts rather than per-line suppress. No new block-level suppression mechanism. - Spec suppression-regex captured-group handling: split on comma, trim each, drop empty, lowercase. Add tests for trailing-space before --> and multi-host with whitespace. - Tighten the absolute-URL regex to require an alphanumeric leading character, rejecting Markdown placeholders like https://... - Add backtick, {, [, ], , to the protocol-relative URL boundary class for JS template literals and JSON object contexts. Explicit note: : intentionally excluded to avoid double-matching absolute URLs. - Fix the lockfile exclusion list: enumerate lockfiles by exact basename (package-lock.json, pnpm-lock.yaml, pnpm-lock.json, yarn.lock, npm-shrinkwrap.json) instead of *-lock.json glob, which missed pnpm-lock.yaml while .yaml is in scope. - Replace the in-memory config_snapshot_mut() sketch with a concrete gix-config file-write plan (read .git/config via gix_config::File::from_path_no_includes, set_raw_value_by, write atomically). Documented as the durable, subprocess-free path. - Replace exec {:?} with a real POSIX single-quote shell-escape function and add tests for paths with spaces, single quotes, $, backticks, backslashes. Finding 10 (revert to top-level ts lint domains) rejected by spec owner: keep ts dev lint domains and ts dev install-hooks.

From 7f9bcb8d9c36070c32aacdbfea3db75fb556ed87 Mon Sep 17 00:00:00 2001 From: Aram Grigoryan <132480+aram356@users.noreply.github.com> Date: Mon, 18 May 2026 14:36:50 -0700 Subject: [PATCH 08/57] Address sixth-review findings; add Implementation Readiness section MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit High-priority fixes: - Add explicit gix-config dependency to the Cargo deps sketch and delete the misleading note that config write is available via Repository::config_snapshot/_mut. The hook installer's persistent config write goes through gix-config::File directly. - Specify base-ref resolution order for --changed-vs in CI: try , refs/heads/, refs/remotes/origin/, refs/tags/. Naive find_reference("main") on a fresh GH Actions checkout would fail because only origin/main exists locally. Failure mode prints all four candidates tried. - Add Implementation Readiness section with explicit start conditions (PR #669 merged, dev refactor agreed, gix version resolves cleanly) and a suggested first-implementation order that front-loads the gix feasibility spike. Medium-priority fixes: - Full-repo audit now explicitly handles tracked-but-missing files, symlinks (skip with warning, not followed), non-regular files, binary files. Five cases enumerated with their warn-and-continue behavior; pseudocode rewritten to show the metadata + read_to_string error handling. - Tighten fenced-Markdown suppression guidance: use the fenced language's native comment syntax (# for bash/sh/toml, // for rust/ts/js), NOT HTML comments (which would be displayed as literal HTML comments inside shell snippets and confuse readers). HTML comments reserved for prose Markdown outside fences. Added a marker-syntax-by-language table. Low-priority fixes: - Remove stale Open Questions: - Q3 (docs.github.com is exact-only) — docs.github.com is now in REFERENCE_HOSTS, so the concern is resolved. - Q5 (Next.js boilerplate URLs) — verified the URLs are only in package-lock.json (excluded), not in package.json. - Renumber remaining Open Questions to close the gaps. --- .../specs/2026-05-18-check-domains-design.md | 244 ++++++++++++++---- 1 file changed, 194 insertions(+), 50 deletions(-) diff --git a/docs/superpowers/specs/2026-05-18-check-domains-design.md b/docs/superpowers/specs/2026-05-18-check-domains-design.md index 9e524fb4..9701562f 100644 --- a/docs/superpowers/specs/2026-05-18-check-domains-design.md +++ b/docs/superpowers/specs/2026-05-18-check-domains-design.md @@ -30,6 +30,58 @@ This design **depends on PR #669** (`Add the Trusted Server CLI`, branch command-surface conventions this design extends.

The refactor is a structural rename, not a behavior change. - Test case 25 (non-UTF-8 staged paths) now explicitly documents the intentional difference from full-repo mode. Staged scans extract hosts from blob content via gix and report normally with a stderr warning about lossy-UTF-8 display; full-repo mode skips because scanning happens through the working-tree read path. Implementers warned not to generalize the full-repo skip rule.

From 00dbb490eda5b370cc8f9fa3f8730d557884a656 Mon Sep 17 00:00:00 2001 From: Aram Grigoryan <132480+aram356@users.noreply.github.com> Date: Mon, 18 May 2026 22:02:48 -0700 Subject: [PATCH 16/57] Address twelfth-review findings on the plan doc High: - Task 1.2: fix config::load_and_validate -> load_validated_config. The current CLI's actual function is load_validated_config; the old name would have failed to compile at the first refactor step. - Phase 4: Move integration-style tests from crates/trusted-server-cli/tests/lint_*.rs into inline #[cfg(test)] mod blocks inside dev/lint/domains.rs. lib.rs declares mod dev; (private), so integration tests under tests/ cannot reach trusted_server_cli::dev::lint::domains::staged_added_lines and similar paths. Added Task 4.0 introducing dev/lint/test_support.rs (cfg(test) pub(crate)) with shared git-fixture helpers; production functions are pub(crate) instead of pub. End-to-end tests via assert_cmd stay in tests/ where they belong (they only need the binary surface). - Phase 5.3: replace raw println!/serde_json::to_string in emit_human/emit_json with the existing crate output helpers write_stdout_line / write_json. Added an explicit note that warn_skip/warn_skip_bytes in Phase 4 must also use write_stderr_line, not eprintln!, matching the existing CLI convention. Medium: - Phase 9.1 clippy: replace 'cargo clippy --workspace --all-targets --all-features' with the two-lane split per CLAUDE.md (--workspace --exclude trusted-server-cli for the wasm-runtime lane; --package trusted-server-cli --target host-target for the CLI lane). The old single-command form misses the host-target CLI warnings. - Task 6.3 test: replace .unwrap() with .expect("should read written file") because workspace clippy denies unwrap_used. Added an inline note warning implementers not to use unwrap() elsewhere either. Low: - All spike-test expect() strings rewritten to follow the 'should ...' convention from CLAUDE.md (e.g., expect("should init gix repo") instead of expect("gix init")). Now consistent with how the rest of the CLI crate writes test expectations. --- .../plans/2026-05-18-ts-dev-lint-domains.md | 260 ++++++++++++++---- 1 file changed, 202 insertions(+), 58 deletions(-) diff --git a/docs/superpowers/plans/2026-05-18-ts-dev-lint-domains.md b/docs/superpowers/plans/2026-05-18-ts-dev-lint-domains.md index 71029b7d..e149296a 100644 --- a/docs/superpowers/plans/2026-05-18-ts-dev-lint-domains.md +++ b/docs/superpowers/plans/2026-05-18-ts-dev-lint-domains.md @@ -202,7 +202,7 @@ fn run_dev(command: dev::DevCommand) -> Result<(), Report> { } fn run_dev_serve(args: &dev::ServeArgs) -> Result<(), Report> { - let validated = config::load_and_validate(args.config.as_deref())?;

Phase 5.3's domains::run consumes both fields and emits a stderr warning for each unused-suppression entry. Added four new TDD tests in Phase 3.7: multi-host suppression applied to violations, partial-match warning, jsdoc/* form suppression, and the no-marker-no-warning case. - Staged non-UTF-8 path handling explicitly specified. Spec test 25 requires staged paths to be REPORTED (not skipped), with lossy display + stderr warning — differs from full-repo mode which skips. Added the path-conversion strategy in Task 4.1 (try from_utf8; fall back to from_utf8_lossy + warn), and a new inline test asserting non-UTF-8 staged paths are surfaced with their blob content intact. Medium: - scan_line tests now cover the spec's multi-host suppression surface (both full match and partial match with warning) and the '* allow-domain:' jsdoc/block-continuation form. Parser tests already cover parsing; these confirm the scanner correctly APPLIES the parsed result. - test_support helper now mandates a fixed gix Signature for all commits, with explicit name/email/time. Avoids dependence on ambient user.name / user.email config so tests pass on clean machines and CI runners without git config. - Task 9.2 self-dogfood now acknowledges 'exit 1 is the success condition' and uses (cmd || true) | jq pipelines so a pipefail-enabled shell doesn't abort on the (expected) exit-1 from the linter. Low: - Task 6.6 step 5 smoke-test now uses 'git init' only (gix is a Rust dep, not a shell command). Removes the misleading 'gix init or use git init' phrasing. - Task 1.2 step 4 replaces the byte-for-byte diff of --help output with semantic grep-based assertions on flag presence and defaults, plus a functional passthrough test via --skip-build. The byte-diff was too brittle (clap can legitimately reformat headings between leaf and child commands); the flag contract is what matters. --- .../plans/2026-05-18-ts-dev-lint-domains.md | 358 ++++++++++++++++-- 1 file changed, 324 insertions(+), 34 deletions(-) diff --git a/docs/superpowers/plans/2026-05-18-ts-dev-lint-domains.md b/docs/superpowers/plans/2026-05-18-ts-dev-lint-domains.md index e149296a..5d6c46d1 100644 --- a/docs/superpowers/plans/2026-05-18-ts-dev-lint-domains.md +++ b/docs/superpowers/plans/2026-05-18-ts-dev-lint-domains.md @@ -221,13 +221,53 @@ fn run_dev_serve(args: &dev::ServeArgs) -> Result<(), Report> { Run: `cargo check --package trusted-server-cli --target "$(rustc -vV | sed -n 's/^host: //p')"` Expected: PASS. -- [ ] **Step 4: Verify the `dev serve --help` output matches the captured baseline** - -Run: `cargo run --package trusted-server-cli --target "$(rustc -vV | sed -n 's/^host: //p')" -- dev serve --help 2>&1 > /tmp/ts-dev-serve-help-after.txt` - -Run: `diff <(sed 's/Usage: ts dev/Usage: ts dev serve/' /tmp/ts-dev-help-before.txt) /tmp/ts-dev-serve-help-after.txt` - -Expected: no output (files identical apart from the `Usage:` line, which legitimately gained the `serve` token).

Low: - Phase 7.2 spec case 25 (non-UTF-8 staged path) now includes an explicit predicates::str::contains stderr assertion for the lossy-path warning. Inline test (Task 4.1) proves the path is not skipped; the E2E test locks the user-facing warning string so it cannot silently disappear. - Phase 5.3 step 3 smoke test switched from 'stage a file in the real repo and re-run' (easy to forget to revert) to a self-cleaning mktemp -d throwaway repo with explicit tempdir cleanup.

Spec §'Per-Line Suppression' says the marker suppresses violations; a listed host that wouldn't have been a violation (already allowed, or not on the line) is unused. Previous logic treated 'host is in extracted set' as 'not unused', which missed the https://example.com // allow-domain: example.com case. Added an explicit test for an already-allowed listed host (11 scan_line tests now, up from 10). - Phase 4 collectors return Report but the call to write_stderr_line (which returns Report) would have failed to compile under '?'. Added DomainsLintError::WriteWarning variant and an in-module warn() helper that wraps write_stderr_line with change_context. Tasks 4.1 / 4.3 / 4.4 now use warn() instead of write_stderr_line directly. Phase 5.3 note clarifies which layer can use which helper.

[PATCH 24/57] Spike: staged-diff gix entry points pinned (gix-only, no shell) Proves the conceptual operation for --staged mode end-to-end against a tempfile-built repo: - Repository init via gix::init - Blob creation via repo.write_blob - Tree construction via repo.edit_tree + editor.upsert + editor.write (requires the tree-editor feature, now enabled) - Commit via repo.commit_as with a fixed test signature - Index construction via gix::index::State + dangerously_push_entry - HEAD tree traversal via tree.traverse().breadthfirst.files() - Index entries via repo.index()?.entries() - Per-blob line diff via gix::diff::blob (imara-diff) Algorithm::Myers + Diff::compute, walking each hunk's `after` range to extract new-side line numbers and content No subprocess, no git binary on

The speculative DomainsLintError::InvalidMode variant is dropped (clap's conflicts_with_all enforces mode exclusivity, so it is never built).

Components: - shell_quote: POSIX single-quote escaping for the ts path embedded in the hook. - render_hook: emits the hook script with the absolute ts path and the `# ts-install-hooks: managed` marker. - is_managed: detects a previously-installed hook by the marker. - write_atomic: temp-file + rename, used for the hook and config. - read/set_local_config_value: gix-config File read/write of /.git/config. - install_hooks: foreign-core.hooksPath preflight (refuse unless --force, then surface the displaced value), unmanaged-hook clobber refusal (back up under --force), executable bit on Unix. Wired as DevCommand::InstallHooks + dev::install_hooks::run, which maps every failure to CliError::EnvironmentError (exit 2). 23 tests: shell_quote escaping, render_hook, is_managed, write_atomic, config round-trip, and seven install_hooks end-to-end scenarios (fresh / idempotent / managed-overwrite / unmanaged-clobber-refusal / force-backup / foreign-hooksPath refusal / force-override). Smoke-tested: hook is executable, carries the marker, git config --local core.hooksPath reads .githooks. --- .../src/dev/install_hooks.rs | 498 ++++++++++++++++++ crates/trusted-server-cli/src/dev/mod.rs | 12 + crates/trusted-server-cli/src/lib.rs | 1 + 3 files changed, 511 insertions(+) create mode 100644 crates/trusted-server-cli/src/dev/install_hooks.rs diff --git a/crates/trusted-server-cli/src/dev/install_hooks.rs b/crates/trusted-server-cli/src/dev/install_hooks.rs new file mode 100644 index 00000000..4388b5c7 --- /dev/null +++ b/crates/trusted-server-cli/src/dev/install_hooks.rs @@ -0,0 +1,498 @@ +//! `ts dev install-hooks` — installs the pre-commit hook that runs +//! `ts dev lint domains --staged`. +//! +//!

A pure rename (or rename + edit) therefore reported every line of the renamed file as added — including pre-existing violations the author never touched. Switch to gix's tree-vs-tree diff with rename tracking (`track_rewrites` with 50% similarity threshold). For staged mode the index is first materialised as a tree via the tree editor, then the same `collect_added_from_trees` path serves both modes. Adds regression tests for pure rename, rename+edit, deletion, multi-hunk same-file edits, and unrelated staged change against a pre-existing violation. Fixture helpers (`stage_all`) now preserve raw bytes on Unix so non-UTF-8 paths reach gix unchanged — the previous `to_string_lossy()` conversion silently replaced invalid bytes, masking spec test case 25. --- .../src/dev/lint/domains.rs | 428 ++++++++++++++---- .../src/dev/lint/test_support.rs | 23 +- crates/trusted-server-cli/tests/common/mod.rs | 23 +- 3 files changed, 379 insertions(+), 95 deletions(-) diff --git a/crates/trusted-server-cli/src/dev/lint/domains.rs b/crates/trusted-server-cli/src/dev/lint/domains.rs index 0d81217e..1f2c404e 100644 --- a/crates/trusted-server-cli/src/dev/lint/domains.rs +++ b/crates/trusted-server-cli/src/dev/lint/domains.rs @@ -3,7 +3,9 @@ //!

The previous `url` field misnamed a full-line excerpt as if it were just a URL. - read_local_config_value now distinguishes "config missing" from "config unreadable", so the foreign-`core.hooksPath` preflight can no longer silently misread a real config. - --help on `ts dev lint domains` notes that the no-args full-repo mode reads working-tree content (may diverge from CI). - New E2E tests: pure rename / deletion / multi-hunk / unrelated staged change against pre-existing violation; --verbose per-file progress; --changed-vs exits 2; full JSON output shape (path, line_no, host, line). - Rename misnamed `markdown_allowed_reference_link_passes` test to `markdown_allowed_inline_link_passes`. --- .../src/dev/install_hooks.rs | 15 +- crates/trusted-server-cli/src/dev/lint/mod.rs | 8 +- .../tests/lint_domains_cli.rs | 176 +++++++++++++++++- 3 files changed, 192 insertions(+), 7 deletions(-) diff --git a/crates/trusted-server-cli/src/dev/install_hooks.rs b/crates/trusted-server-cli/src/dev/install_hooks.rs index 7ef9c61b..2503693a 100644 --- a/crates/trusted-server-cli/src/dev/install_hooks.rs +++ b/crates/trusted-server-cli/src/dev/install_hooks.rs @@ -129,16 +129,21 @@ fn write_atomic(path: &Path, content: &[u8]) -> Result<(), Report Result, Report> { let config_path = repo.git_dir().join("config"); - let file = match GixConfigFile::from_path_no_includes(config_path, gix_config::Source::Local) { - Ok(f) => f, - Err(_) => return Ok(None), - }; + if !config_path.exists() { + return Ok(None); + } + let file = GixConfigFile::from_path_no_includes(config_path, gix_config::Source::Local) + .change_context(InstallHooksError::ConfigWrite)?; Ok(file .raw_value(dotted_key) .ok() diff --git a/crates/trusted-server-cli/src/dev/lint/mod.rs b/crates/trusted-server-cli/src/dev/lint/mod.rs index 9dd11f5d..7da70a59 100644 --- a/crates/trusted-server-cli/src/dev/lint/mod.rs +++ b/crates/trusted-server-cli/src/dev/lint/mod.rs @@ -19,6 +19,11 @@ pub(crate) mod test_support; #[derive(Debug, Subcommand)] pub enum LintCommand { /// Lint URL hosts in source/config/docs. + /// + /// With no flags or paths, scans every tracked file's *working-tree* + /// content (includes unstaged edits, so a local audit may diverge + /// from CI on the same commit).

Update spec and plan to match the implemented shape: `path, line_no, host, line`. The new names describe what the fields contain. - Stale resolved-gix section: spec previously declared "No tree-vs- tree Platform machinery is used" and prescribed manual path-to- blob map walking. That approach silently broke renames, so the implementation now uses `old_tree.changes()` with `track_rewrites` and `for_each_to_obtain_tree`. Update the spec to describe the current approach and explain why the earlier resolution was reversed. Also refresh the staged/changed-vs pseudocode sketches. - Spec case 28 coverage gap: add an E2E test for the "feature branch behind base" topology where merge-base(base, HEAD) == HEAD, so the diff is empty even when the base ref has introduced a violation. --- .../tests/lint_domains_cli.rs | 73 ++++++++++ .../plans/2026-05-18-ts-dev-lint-domains.md | 7 +- .../specs/2026-05-18-check-domains-design.md | 133 +++++++++--------- 3 files changed, 141 insertions(+), 72 deletions(-) diff --git a/crates/trusted-server-cli/tests/lint_domains_cli.rs b/crates/trusted-server-cli/tests/lint_domains_cli.rs index c923d059..2a63625c 100644 --- a/crates/trusted-server-cli/tests/lint_domains_cli.rs +++ b/crates/trusted-server-cli/tests/lint_domains_cli.rs @@ -306,6 +306,79 @@ fn changed_vs_reports_feature_branch_lines() { .stdout(predicate::str::contains("disallowed host test.com")); } +/// Spec case 28: when HEAD is behind the base ref, the merge-base +/// is HEAD itself and the diff is empty — so no violations are +/// reported even if the base ref has introduced one.

Both the absolute and protocol-relative regexes now skip an optional `(?:[^/?\s#]+@)?` userinfo group before capturing the host. Same fix for `//github.com@evil/x`. - Explicit absolute path bypassed self-exclusion: the old check compared the user's path string against the repo-relative `SELF_PATH`, so `ts dev lint domains /abs/.../domains.rs` scanned the linter's own source. `path_is_scanned` now uses `Path::ends_with(SELF_PATH)`, which is component-aware and works for both repo-relative and absolute path forms. A guard test confirms a substring match like `notrusted-server-cli/.../domains.rs` is NOT excluded. - Hook backups can collide within one second: `--force` named backups `pre-commit.bak.`, so two forced installs in the same second clobbered each other.

Future agents reading the spec or scaffolding code from the plan would have re-introduced the bypass. Updated both regex blocks in the spec and both scaffold snippets in the plan to match the implementation, with the why-userinfo-is-skipped rationale alongside. - E2E matrix had four remaining spec gaps. Added: * html_file_outside_fixtures_is_scanned — spec case 32 positive half: a `.html` file under crates/trusted-server-core/src/ (NOT a fixtures path) is scanned. * integration_test_fixture_tsx_is_scanned — spec case 33: proves the `**/fixtures/**` blanket exclusion was removed by scanning a `.tsx` under crates/integration-tests/fixtures/... * markdown_fenced_block_with_allowed_reference_passes — spec case 41: a fenced block referencing `https://docs.rs/clap` is a REFERENCE_HOSTS allow and exits 0. * full_repo_in_bare_repo_exits_two — spec case 45: bare repo (no workdir) yields exit 2 in full-repo mode. --- .../tests/lint_domains_cli.rs | 91 ++++++++++++ .../plans/2026-05-18-ts-dev-lint-domains.md | 12 +- .../specs/2026-05-18-check-domains-design.md | 134 ++++++++++-------- 3 files changed, 173 insertions(+), 64 deletions(-) diff --git a/crates/trusted-server-cli/tests/lint_domains_cli.rs b/crates/trusted-server-cli/tests/lint_domains_cli.rs index 60c829bb..69bc3362 100644 --- a/crates/trusted-server-cli/tests/lint_domains_cli.rs +++ b/crates/trusted-server-cli/tests/lint_domains_cli.rs @@ -544,6 +544,97 @@ curl https://test.com/foo } } +/// Spec case 32 (positive half): an `.html` file outside the +/// integrations-fixtures exclusion is scanned normally. +#[test] +fn html_file_outside_fixtures_is_scanned() { + let temp = tempfile::tempdir().expect("should create tempdir"); + let repo = common::init_repo(temp.path()); + + let nested = temp.path().join("crates/trusted-server-core/src"); + std::fs::create_dir_all(&nested).expect("nested dir"); + std::fs::write( + nested.join("html_processor.test.html"), + "x\n", + ) + .expect("write html"); + + common::stage_all(&repo); + common::commit_all(&repo, "seed html"); + + ts_in(&temp) + .args(["dev", "lint", "domains"]) + .assert() + .code(1) + .stdout(predicate::str::contains( + "html_processor.test.html:1: disallowed host test.com", + )); +} + +/// Spec case 33: proves the `**/fixtures/**` blanket exclusion was +/// removed.

Tightening the regex to avoid this would also weaken the userinfo-bypass protection — `//github.com@evil.example` at end of line could slip through. Preserving the bypass protection takes priority; this is a known limitation users can suppress per-line with `// allow-domain: test.com`. Adds a behavior-locking acceptance test and a spec bullet under the protocol-relative regex's Known limitations. --- .../src/dev/lint/domains.rs | 14 +++ .../specs/2026-05-18-check-domains-design.md | 112 +++++++++--------- 2 files changed, 71 insertions(+), 55 deletions(-) diff --git a/crates/trusted-server-cli/src/dev/lint/domains.rs b/crates/trusted-server-cli/src/dev/lint/domains.rs index cc990e00..e72e2123 100644 --- a/crates/trusted-server-cli/src/dev/lint/domains.rs +++ b/crates/trusted-server-cli/src/dev/lint/domains.rs @@ -515,6 +515,20 @@ mod protocol_relative_tests { vec!["evil.example"] ); } + + /// Documents an accepted limitation: a `//email@domain` token in + /// a code comment is indistinguishable from a protocol-relative + /// URL with userinfo, and so is reported.
