) Fixes #942. ## The bug A job calling a reusable workflow cannot itself carry an `environment:` key ([GitHub's supported-keywords list](https://docs.github.com/en/actions/reference/workflows-and-actions/reusing-workflow-configurations) omits it, and the combination is a hard workflow-syntax error), but the documented `deploy-site.yml` caller stub bound one on the same job as `uses:` anyway. As documented, the stub would fail to even parse. ## No redesign needed `deploy-site-task.yml`'s own `deploy` job already binds `environment: ${{ inputs.environment }}` on itself, an ordinary job (not a `uses:` job). Per GitHub's documented cross-repository behavior (the `github` context, and an OIDC token's `sub` claim, always attribute the environment to the *caller*), that already resolves against the caller's own GitHub Environment store. The caller's `secrets: DEPLOY_SSH_PRIVATE_KEY: ${{ secrets.DEPLOY_SSH_PRIVATE_KEY }}` mapping exists only to put the name in the task's reach and evaluates empty at the caller; the task's own environment binding overrides that empty value with the real one. ## Confirmed with a live run Dispatched `deploy-site-task.yml` cross-repository from `ptr727/Blog`, caller job carrying no `environment:` key, targeting Blog's real `staging` environment: `DEPLOY_SSH_PRIVATE_KEY` resolved (masked, non-empty), and only the separately-tracked `SITE_BASE_URL` naming mismatch was reported missing. Run: https://github.com/ptr727/Blog/actions/runs/32618245296 ## What changed - `docs/reusable-workflows.md`: drop the job-level `environment:` line from the caller-stub example, correct the surrounding prose's false premise, tick the Stage 5 rollout checklist item with the run URL as evidence. - `.github/workflows/deploy-site-task.yml`: correct the same false premise in the job's own comment (no functional change - the job's `environment:` binding was already right). - `spec/files.json`: drop the `"\n environment:"` token from `deploy-site.yml`'s interface contract, which mechanically required the now-known-invalid shape. - `spec/audit.py`: fix the `deploy_stub`/`deploy_contract` self-test fixture to match, drop the case whose premise the fix inverts. `python3 spec/audit.py --selftest` passes. 🤖 Generated with [Claude Code](https://claude.com/claude-code) <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Documentation** * Clarified deployment environment and secret handling in reusable workflows. * Added guidance for cross-repository deployments, required configuration, hooks, environment variables, verification tokens, and references. * **Bug Fixes** * Corrected environment settings for reusable deployment tasks. * Removed unsupported caller-level environment configuration. * Preserved validation for secret mapping and required permissions. * Improved audit feedback for invalid deployment configuration. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
Enforce shfmt and Broaden Shell-Script Discovery in the Lint Gate Fixes #950. ## The gap `validate-task.yml`'s shell step ran shellcheck only, and both it and `docker_lint.py`'s `shellcheck` linter discovered targets from a bare `*.sh` glob. CODESTYLE.md's Shell section and the `shell-codestyle` Skill never named shfmt at all, so nothing documented or enforced the formatter half of the shell clean-compile, and a tracked script meant to run as a bare command (no extension, shebang only) was invisible to both the glob and, before this change, to shfmt. ## The fix - `.github/workflows/validate-task.yml`: the shell step now also runs `mvdan/shfmt:latest -d`, and its target list is the `*.sh` glob plus every tracked, extensionless file whose shebang names bash or sh. - `scripts/docker_lint.py`: added a `shfmt` linter entry (shares the shellcheck image's target-discovery shape) and a `discover_shebang` field on `Linter` that both shellcheck and shfmt set, backed by a new `extensionless_shell_scripts()`/`has_shell_shebang()` pair so the local wrapper matches CI exactly. Tests added in `scripts/tests/test_docker_lint.py`. - `.agents/skills/shell-codestyle/SKILL.md` (regenerated into `.github/skills/` and `.claude-plugin/` via `build_dist.py`), `CODESTYLE.md`, `GOVERNANCE.md`, and the two `host-setup/*/README.md` files: document the shellcheck-plus-shfmt clean-compile and the broadened discovery. ## Verified Full doc-lint set (`markdownlint`, `cspell`, `actionlint`, `editorconfig-checker`), `shellcheck`, `shfmt`, and `PSScriptAnalyzer` all pass clean via `scripts/docker_lint.py` with no `--linter` filter. `scripts/repo_gate.py`, `scripts/prose_lint.py --diff origin/develop`, and the full `scripts/tests/` suite (790 tests) all pass. Confirmed the extensionless-script gap directly: reproduced Blog's `ops/vps-backup-pull` shape in a scratch repo, showed `docker_lint.py` missed a real shfmt formatting violation in it before this change and catches it after. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **New Features** * Shell validation now includes `.sh` files and extensionless Bash/sh scripts identified by their shebang. * Validation runs both ShellCheck and shfmt in CI and local tooling. * **Documentation** * Updated shell coding, governance, and setup guidance for the expanded validation workflow. * **Refactor** * Standardized shell formatting across setup and configuration scripts without changing behavior. * **Tests** * Added coverage for script discovery, formatting arguments, and non-shell file exclusion. <!-- end of auto-generated comment: release notes by coderabbit.ai -->

Walk env's Full Argument Grammar, Fix read's EOF Quirk Fixes 2 real findings from qodo-code-review on PR #952 (the develop -> main promotion PR carrying #951's shell-lint-gate work), both reproduced before the fix. ## env NAME=VALUE and operand-taking flags Both shebang parsers only walked past simple boolean flags before `env`'s command, so `#!/usr/bin/env FOO=1 bash` (a real pattern: environment assignments before the command) fell through as unclassified, while `#!/usr/bin/env -u bash python` (a real pattern: `-u NAME` unsets an env var, taking `bash` as -u's operand rather than naming the interpreter) was misclassified as a bash script. - `scripts/docker_lint.py`: `shell_shebang_interpreter` now walks past `NAME=VALUE` assignments (`_is_env_assignment`) and past `env` options that consume a separate operand token (`-u`/`--unset`, `-C`/`--chdir`), in addition to `-S`/`--split-string` and plain boolean flags. - `.github/workflows/validate-task.yml`: `is_shell_shebang` gained the same walk. ## A no-trailing-newline shebang silently skipped in CI `IFS= read -r first_line < "$file"` returns non-zero at EOF even after correctly filling `first_line`, so the CI step's `... && IFS= read -r first_line < "$file" && is_shell_shebang ...` chain short-circuited before the shebang check ever ran, for a tracked extensionless script whose shebang line is also its last line with no trailing newline. `docker_lint.py`'s `readline()` has no such quirk, so this was a real CI/local divergence, not a difference in what was being checked. - `.github/workflows/validate-task.yml`: reads into `first_line` first, tolerates `read`'s own EOF exit code with `|| true`, then checks the content regardless. ## Verified Reproduced both false-positive/false-negative shebang cases and the no-trailing-newline case end to end, in a scratch repo, through the CI step's exact commands and through `docker_lint.py`. Added `test_shell_shebang_interpreter_walks_past_env_grammar` and `test_extensionless_shebang_script_with_no_trailing_newline_is_picked_up` to `scripts/tests/test_docker_lint.py`. Full test suite (795 tests), ruff, mypy, actionlint, `repo_gate.py`, `prose_lint.py --diff origin/develop`, and the complete `docker_lint.py` run (all 7 linters) all pass clean. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Bug Fixes** * Improved detection of extensionless shell scripts, including files without a final newline. * More accurately recognizes shell interpreters in complex shebang commands using environment assignments, options, argument separators, and split-string syntax. * Validation now more reliably identifies Bash and sh scripts, reducing incorrect linting results. * **Tests** * Added coverage for trailing-newline omissions and expanded shebang parsing scenarios. <!-- end of auto-generated comment: release notes by coderabbit.ai -->

Reject Symlinks From Shebang Discovery, Propagate read Failures Fixes 2 findings from coderabbitai on PR #952 (the develop -> main promotion PR carrying #951's shell-lint-gate work), both reproduced before the fix. ## A tracked symlink could read an arbitrary host file The extensionless-shebang scan opens each candidate file to check its first line, host-side, before Docker ever starts. `[ -f "$file" ]` and Python's `Path.open()` both follow a symlink, so a tracked symlink pointing outside the checkout (`ops/evil -> /etc/shadow`, or anywhere else the CI runner or a dev's own machine can read) had its target's first line read on the host as part of merely checking whether it looks like a shell script. Reproduced: a symlink to a file containing `TOP SECRET` content was read through `read <` on the CI side and `Path.open()` on the Python side. - `.github/workflows/validate-task.yml`: added `[ ! -h "$file" ]` (checks the tracked path itself via `lstat`, never follows it) alongside the existing `-f` check, before any read. - `scripts/docker_lint.py`: `has_shell_shebang` now checks `is_symlink()` first and returns `False` without ever opening the path. - `scripts/tests/test_docker_lint.py`: added `track_symlink()` and two regression tests proving a symlinked extensionless script is excluded from discovery and never opened. This matches established fleet precedent: `build_dist.py`, `skills_install.py`, and `carry.py` (`spec/`) already reject symlinks for the same reason, confirmed by their own existing test suites passing unaffected. ## `read`'s `|| true` masked a genuine read failure too `IFS= read -r first_line < "$file" || true` (landed in #953) tolerated the harmless no-trailing-newline EOF case, but the same `|| true` also swallowed a genuine read failure (permission denied, file removed mid-run), silently skipping a tracked script CI should have linted. - `.github/workflows/validate-task.yml`: replaced the `read`/`|| true` pair with `first_line="$(head -n 1 -- "$file")"`, which reads a no-trailing-newline file cleanly (exit 0) while still failing loudly on a genuine read error, per CodeRabbit's own verified reproduction. ## Verified Reproduced all three cases end to end in a scratch repo: a tracked symlink to a file containing secret content is excluded from discovery on both the CI step's exact commands and `docker_lint.py` (and never opened, confirmed via the new Python test), a no-trailing-newline script is still discovered and read correctly, and a genuine permission-denied read aborts the script instead of being silently skipped. Full test suite (797 tests), ruff, mypy, actionlint, `repo_gate.py`, `prose_lint.py --diff origin/develop`, and the complete `docker_lint.py` run (all 7 linters) all pass clean. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Bug Fixes** * Shell linting now excludes symbolic links from shell-script checks. * Symlink targets are no longer inspected when detecting shell scripts. * Shell-script discovery now handles candidate shebangs more reliably. * **Tests** * Added coverage for extensionless symlinks and symlink shebang detection. <!-- end of auto-generated comment: release notes by coderabbit.ai -->

#956) Propagate has_shell_shebang's Read Failures Instead of Swallowing Them Fixes one real finding from coderabbitai on PR #952 (declines the other; see below). ## Propagate shell-file read failures `has_shell_shebang` caught every `OSError` from `path.open()`/ `readline()` and returned `False`, the same value it returns for a file that legitimately isn't a shell script. Unlike the CI bash side (where `read` fails at true EOF even after filling the variable), Python's `readline()` never raises for EOF, an empty read is just `b''` with no exception, so every `OSError` this caught was a genuine failure (permission denied, the file vanishing between `git ls-files` and the read, disk I/O). Swallowing it meant a tracked file this couldn't open silently dropped out of the lint target list, and `lint()` could report success having never actually checked it. - `scripts/docker_lint.py`: `has_shell_shebang` now raises `CommandFailed` on a genuine read `OSError`, matching the pattern `ls_files` already uses for its own I/O failures. The deliberate `False` cases (a symlink, invalid UTF-8) are unchanged. - `scripts/tests/test_docker_lint.py`: added `test_has_shell_shebang_raises_rather_than_swallowing_a_read_failure`, confirming a mocked `PermissionError` surfaces as `CommandFailed` instead of a silent `False`. ## Declined: reject symlinks in every shell-discovery path The `*.sh`-glob-matched branch (`ls_files(root, linter.patterns)`) never reads file content on the host at all, before or after this chain's own symlink fix (#955): it only builds a path list and passes it to `docker run ... -- files`. Confirmed empirically that a symlink processed *inside* the container cannot escape to the host filesystem regardless of target: `docker run -v "$PWD":/mnt alpine sh -c 'cat /mnt/link-to-etc-shadow'` reads the container's own `/etc/shadow` (byte-identical to reading it directly), and a symlink to a real host tmp file that exists on the host but not in the container's own filesystem tree fails with "No such file or directory" (i.e., the container's own root, not the host's, is what a bind-mounted symlink resolves against). The host-side read this chain actually guards against is specific to `extensionless_shell_scripts`' shebang peek, which already rejects symlinks (#955); the glob-matched branch has no equivalent host-side read to guard. ## Verified Full test suite (798 tests), ruff, mypy, `repo_gate.py`, `prose_lint.py --diff origin/develop`, and the complete `docker_lint.py` run (all 7 linters) all pass clean. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Bug Fixes** * Improved handling of symbolic links during shell-file detection. * File read failures now report a clear error with the affected path instead of being silently ignored. * **Tests** * Added coverage to verify that permission-related read failures are surfaced correctly. <!-- end of auto-generated comment: release notes by coderabbit.ai -->

## Summary Five `host-setup/` sites converted a precondition-check failure into an empty or apparently-safe result with `|| true` or `2>/dev/null`, then proceeded into a download, package install, sudoers-file write, or release upgrade as if the check had passed. This is a recurring CodeRabbit finding, raised across PR #951 and PR #952 and correctly declined both times as pre-existing and out of scope for those PRs. Per `pr-review-conduct`'s outcome 5 ("keeps recurring, so fix the class, not the instance"), this PR fixes the class. ## Per-site disposition Four sites now distinguish "the check ran and legitimately found nothing" from "the check itself failed to run," and fail closed before the mutation they guard: - `host-setup/linux/install-tools.sh` `apt_install_displacing()`: a failed `apt-get -s install` simulation now aborts instead of reading as "no removals" before the real install runs. - `host-setup/linux/install-tools.sh` sudoers scan: `grep` exit 1 (no matches, the ordinary case) still proceeds; any higher exit now aborts before writing or deleting sudoers files. - `host-setup/linux/upgrade-host.sh` `release_preconditions()`: a `dpkg --audit` that fails to run now aborts instead of reading as "no half-configured packages" before the release upgrade. - `host-setup/linux/upgrade-host.sh` `upgradable_count()`: this one only ever backs a `--status` report line, nothing downstream mutates on the strength of it, so a failed `apt list` now reports "unknown" rather than a misleading `0`. `host-setup/bootstrap.sh` `resolve_ref()` stays lenient, now with an inline comment explaining why: it gates no mutation. `download_tree` falls back to fetching `$REF` by name when resolution fails, exactly as it would if `resolve_ref` did not exist, and it has its own `die` on a real download failure. ## Verification - Docker-based `shellcheck` (`koalaman/shellcheck:stable`) and `shfmt -d`: both clean on the three changed files, and via `scripts/docker_lint.py --linter shellcheck --linter shfmt --linter cspell` across the whole repo. - `python3 -m unittest scripts.tests.test_bootstrap scripts.tests.test_host_gate`: 104 tests, all pass. - Live-exercised each fixed function's logic on this Linux host (real run plus a simulated-failure case for each), confirming the real case is unaffected and the simulated failure now fails closed rather than silently proceeding. Fixes #954 🤖 Generated with [Claude Code](https://claude.com/claude-code) <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Bug Fixes** * Improved host setup reliability by detecting and reporting package simulation failures instead of continuing with incomplete results. * Prevented potentially unsafe configuration changes when system scans encounter errors. * Improved upgrade status reporting by distinguishing failed checks from systems with no available updates. * Preserved and reported package audit failures during release readiness checks. * Clarified behavior when requested revisions cannot be resolved, while allowing download errors to be reported separately. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
