fix(ci): pin third-party actions to full commit SHAs

The account's Actions policy requires a full-length SHA ref. A tag or branch ref is refused at
startup — startup_failure, no jobs, "this workflow graph cannot be shown" — so these workflows
could not run at all. This resolves each ref to the commit it currently points at and records the
ref in a trailing comment, e.g. actions/checkout@<sha> # v4.

dtolnay/rust-toolchain takes its toolchain from the ref itself, so those steps also gained an
explicit with: toolchain: input; without it, a SHA ref would silently lose the channel.

No behaviour is intended to change beyond the pins.

Summary by CodeRabbit

  • Security

    • Updated automated workflows to use fixed action versions, improving build and deployment consistency.
    • Security scanning and code analysis workflows now use stable action references.
  • Maintenance

    • Added protection against outdated CodeQL runs by cancelling superseded executions.
    • Existing build, testing, publishing, deployment, synchronisation, and notification workflows continue to operate as before.

Walkthrough

The workflows replace mutable GitHub Actions tags with immutable commit SHAs. Version comments remain where specified. Build, Pages, security, synchronisation, and notification workflow behaviour is otherwise unchanged.

Provide the required toolchain input.

dtolnay/rust-toolchain requires toolchain. Both the previous @v1 action and the pinned commit exit with 'toolchain' is a required input when the input is omitted. extension-build therefore fails during Rust setup, before the build commands run. Add toolchain: v1.

github gh-actions-lock actions.lock generated file purpose update workflow references documentation

💡 Result:

<search_synthesis>
The actions.lock file is a central component of GitHub&#39;s Workflow Dependency Pinning effort [1][2]. Its primary purpose is to record the resolved transitive dependency graph for a repository&#39;s GitHub Actions workflows, ensuring that the exact commit SHAs executed on a runner are verified and consistent [1][2]. Key aspects of the actions.lock file include: Purpose and Functionality - Security and Integrity: By pinning every action to a verified commit SHA, the lockfile helps prevent "impostor commit" attacks and ensures that workflow dependencies remain immutable [1]. - Verification: Workflows onboarded to the lockfile enforce that all dependencies are present in the file. The system verifies that the locked commit exists within the specified reference and blocks redirects or mismatches at runtime [1]. - Centralized Management: Unlike older methods that might pin actions individually within each YAML file, the actions.lock file provides a single, authoritative source of truth for all workflow dependencies in a repository [1][2]. Technical Details - Location: The canonical path for the file is .github/workflows/actions.lock [1][3]. - Format: It is a YAML document containing three top-level keys: version (schema version), dependencies (a deduplicated graph of actions), and workflows (a mapping of each workflow to its flat, transitive list of dependencies) [2][3]. - Tooling: The gh-actions-lock GitHub CLI extension is the primary tool used to generate and maintain this file [1][2]. Updating Workflow References To update or manage the lockfile, you typically use the gh actions-lock command [1]. When you modify a workflow (e.g., changing an action version or adding a new dependency), you must run gh actions-lock to regenerate the lockfile and ensure it reflects the current state of your workflows [1]. This process ensures that the lockfile remains synchronized with the actual uses: references defined in your workflow YAML files [1]. Note: While some community tools or older implementations may use variations like actions-lock.json [4][5], the official GitHub-supported format and tooling (via gh-actions-lock) utilize the .github/workflows/actions.lock YAML file [1][2]. Always refer to the official github/gh-actions-lock repository for the most current implementation details [1].

The > lockfile format, command flags, and behavior may change without notice between > releases. Use it, file issues, and expect rough edges. ## Background gh-actions-lock is part of GitHub&`#39`;s Workflow Dependency Pinning effort. It gives repositories a lockfile that pins every workflow dependency to a verified commit, so what runs on the runner is exactly what you locked. Development is ongoing and behavior may still change. Contributions are welcome. See CONTRIBUTING.md to get started. ## Requirements Requires the `gh` CLI. Install it first, then install the extension: ```bash gh extension install github/gh-actions-lock ``` ## Usage Scan every workflow under `.github/workflows/` directory, pin each resolvable action to a SHA, and update the lockfile: ```bash gh actions-lock ``` After the initial run to onboard workflows, you will need to run `gh actions-lock` when: - A new workflow is created that has `uses` dependencies. - An existing workflow adds or removes `uses` dependencies. A full-directory run (`gh actions-lock` with no path arguments) also prunes lockfile entries for workflows that have been deleted from `.github/workflows/`, dropping any dependencies left orphaned by the removal. Scoped runs that name specific workflows never prune out-of-scope entries. Pins to branches or partial versions (e.g. `main`, `v4`) are trusted from the lockfile and not re-resolved on a normal run. To bump them to the current upstream commit, run: ```bash gh actions-lock --relock ``` `--relock` re-resolves refs that have legitimately moved and rewrites the lockfile to the new SHA. Suspicious pins whose recorded commit is no longer reachable upstream are left as errors — use `--accept-moved` to re-resolve those as well. ### Self repository actions (`$/…`) `uses: $/…` references an action or reusable workflow in the **same repository** as the defining file, resolved at the **running commit**. Because it always resolves to that repository&amp;`#39`;s running SHA it is **inherently pinned** — no lockfile entry is required, and it is valid anywhere a relative `./…` reference is: ```yaml steps: - uses: $/actions/my-action # same-repo action, inherently pinned jobs: call: uses: $/.github/workflows/reusable.yml # same-repo reusable workflow ``` A trailing `@ref` (e.g. `$/actions/my-action@v1`) is rejected — the ref is always the running commit. Same-repo `./…` composite action references are automatically converted to `$/…` on fix runs. This rewrites `./…` steps both in your workflows and in your in-repo composite action definitions (`action.yml`). Only `./…` paths that resolve to an in-repo action file are rewritten. To leave `./…` refs untouched, opt out with `--no-migrate-local-actions`: ```bash gh actions-lock --no-migrate-local-actions ``` ## How it works A repo gets a lockfile (located at `.github/workflows/actions.lock`) and workflows are onboarded to the lockfile on a per-workflow basis. Workflows that are onboarded to the lockfile enforce that all dependencies are present in the lockfile and guarantees that the locked commit for an Action is what&`#39`;s executed on the runner. Lockfiles are also verified for forgeries. The sha must exist in the refs it&`#39`;s stated to exist in.

The lockfile records the resolved transitive dependency graph for a repository&`#39`;s workflows so tools can audit and verify the exact action pins in use. ## Background This project provides the shared, authoritative lockfile format that GitHub Actions tooling uses to record and verify resolved dependency pins. It is part of GitHub&`#39`;s broader Workflow Dependency Pinning effort, and the schema and parser will continue to evolve toward a stable `v1.0.0`. Contributions are welcome — see CONTRIBUTING.md. ## Installation ```sh go get github.com/github/actions-lockfile/go/pkg/lockfile ``` The Go module lives under `go/` so the repository can grow additional language bindings around the same lockfile schema. ## Usage ### Parse a lockfile and look up a workflow&`#39`;s pins ```go package main import ( "fmt" "os" lockfile "github.com/github/actions-lockfile/go/pkg/lockfile" ) func main() { contents, err := os.ReadFile(lockfile.Path) // ".github/workflows/actions.lock" if err != nil { panic(err) } file, err := lockfile.Parse(contents) if err != nil { panic(err) } pins, ok := file.LookupWorkflow(".github/workflows/release.yml") if !ok { fmt.Println("workflow not present in lockfile") return } for _, key := range pins { fmt.Println(key) // e.g. actions/checkout@v6.0.2 } } ``` ### Surface structured parse errors `Parse` returns a `*lockfile.ParseError` carrying line and column for semantic failures, so callers can anchor diagnostics on the lockfile itself instead of scraping yaml.v3&`#39`;s error string. ```go file, err := lockfile.Parse(contents) if err != nil { var perr *lockfile.ParseError if errors.As(err, &perr) { fmt.Printf("%s:%d:%d: %s\n", lockfile.Path, perr.Line, perr.Column, perr.Msg) return } panic(err) } _ = file ``` ## Schema The lockfile is a YAML document whose shape is defined by a JSON Schema 2020-12 document embedded in the package and reachable via `lockfile.Schema()`. The current schema version is `v0.0.2` (`schema/lockfile-v0.0.2.json`). The on-disk file lives at `Path` (`.github/workflows/actions.lock`) and has three top-level keys: ```yaml version: v0.0.2 workflows: # workflow path -> flat, transitive list of pin keys .github/workflows/release.yml: - actions/checkout@v6.0.2 dependencies: # pin key -> resolved action metadata actions/checkout@v6.0.2: ref: v6.0.2 commit: sha1-de0fac2e... owner_id: 44036562 repo_id: 197814629 ``` A pin key is `OWNER/REPO@REF`. The same key appears in both `workflows` (as flat transitive lists) and `dependencies` (as deduplicated graph entries with `uses:` links to direct dependencies). The parser also reads v0.0.1 lockfiles (which used `tag`/`branch` fields and `:algo-hex` suffixed pin keys) and normalizes them to the v0.0.2 `File` struct. Use `ParseWithPolicy` with a `VersionPolicy` to control which versions are accepted. ## Compatibility and stability - The Go module follows semver. The publicly documented exported surface is …[truncated] <title>go/pkg/lockfile/lockfile.go</title> https://github.com/github/actions-lockfile/blob/main/go/pkg/lockfile/lockfile.go // Path is the canonical repo-relative location of the dependency lockfile. const Path = ".github/workflows/actions.lock" // CLIName is the canonical name of the CLI extension that manages lockfiles. const CLIName = "gh actions-lock" ... // File is the parsed lockfile shape. // // # .github/workflows/actions.lock // version: v0.0.1 // workflows: // .github/workflows/deploy.yml: // - actions/checkout@v6 // dependencies: // actions/checkout@v4.3.1: // ref: v4.3.1 // commit: sha1-34e114876b0b11c390a56381ad16ebd13914f8d5 // owner_id: 44036562 // repo_id: 197814629 // uses: // - actions/cache@v4.0.0 // ... // Dependencies is the deduplicated action DAG; each entry&`#39`;s uses: list names // its direct nested dependencies as canonical pin keys.

Pins all actions (including transitive dependencies) to the exact commit SHAs with integrity hashes. ... GitHub Actions has no native lockfile mechanism. Version tags like `@v4` can be silently retagged, and composite actions pull in transitive dependencies you can&`#39`;t see. This tool fixes that. ... ## Recommended Workflow ... ### Step 1: Generate Your Initial Lockfile ... Run an action in `generate` mode to create your lockfile: ... ```yaml name: Generate Lockfile on: workflow_dispatch jobs: generate: runs-on: ubuntu-latest permissions: # Gives the default GITHUB_TOKEN write permission to commit and push the # added or changed files to the repository. contents: write steps: - uses: actions/checkout@v6 - uses: gjtorikian/gh-actions-lockfile@v1 with: mode: generate - name: Commit lockfile # Commit the changed lockfile back to the repository uses: stefanzweifel/git-auto-commit-action@v7 # or, something like # run: | # git add .github/actions.lock.json # git commit -m "Add actions lockfile" # git push ... You really only need to generate this initial lockfile once, so choose whichever version makes the most sense. ... ### Step 2: Verify on Every Action Run ... Add verification to your CI workflow. If verification fails, the lockfile is automatically regenerated and committed to the PR: ... ```yaml name: Verify Actions # change this to whichever events matter to you on: [pull_request] permissions: pull-requests: write jobs: verify-actions: runs-on: ubuntu-latest steps: - uses: actions/checkout@v6 - uses: gjtorikian/gh-actions-lockfile@v1 with: mode: verify update-lockfile: needs: verify-actions if: failure() runs-on: ubuntu-latest permissions: # Gives the default GITHUB_TOKEN write permission to commit and push the # added or changed files to the repository. contents: write steps: - uses: actions/checkout@v6 with: ref: ${{ github.head_ref }} - uses: gjtorikian/gh-actions-lockfile@v1 with: mode: generate - uses: stefanzweifel/git-auto-commit-action@v7 with: commit_message: "Update actions lockfile" file_pattern: ".github/actions.lock.json" ``` ... When you update an action version (e.g., `actions/checkout@v4` to `@v5`), _or if the action ref changes_ outside of your control, the verify job will fail, triggering the update job to regenerate and commit the lockfile to your PR automatically. ... #### Manual Updates ... If you prefer to update the lockfile locally instead of auto-committing via GitHub Actions, you can: ... 1. Make your workflow changes 2. Regenerate the lockfile: ```bash npx gh-actions-lockfile generate ``` 3. Review the lockfile diff to confirm expected changes 4. Commit both the workflow and lockfile changes together ... - **New dependency detected**: A composite action you use added a new transitive dependency - **SHA mismatch**: An upstream maintainer force-pushed or retagged a version (this is a potential supply chain concern) - **Integrity mismatch**: The tarball content has changed for the same SHA (rare, but a serious supply chain concern) - **Missing action**: An action was removed from your workflow but is still in the lockfile ... When you run `verify`, the tool checks that all locked action refs still resolve to the same commit SHAs. This detects if an upstream maintainer has re-pointed a tag to a different commit (a supply chain concern known as "tag hijacking"). ... ### SHA-Only Mode ... For maximum security, you can enforce that all action references in your workflows use full 40-character commit SHAs instead of tags or branches: ... ```bash gh-actions-lockfile generate --require-sha ... This fails if any workflow uses a tag like `@v4` instead of a full SHA like `@b4ffde65f46336ab88eb53be808477a3936bae11`. ... ### GitHub Action (recommended) ... Add this action to your workflow to verify the lockfile: ... ```yaml - uses: gjtorikian/gh-actions-lockfile@v1 with: mode: verify # or &`#39`;genera…[truncated]

official github gh-actions-lock documentation check audit stale workflow action lock mismatch changed SHA

💡 Result:

<search_synthesis>
The gh-actions-lock tool is a GitHub CLI extension designed to manage workflow dependency pinning by creating and maintaining a lockfile at.github/workflows/actions.lock [1][2]. This lockfile records the resolved transitive dependency graph for a repository&#39;s workflows, ensuring that the exact commit SHA used by an action is verified and enforced during execution [1][3]. When a workflow&#39;s action references (e.g., tags or branches) are updated in the YAML files but the lockfile is not updated, a mismatch occurs [4][5]. Because the lockfile enforces that the recorded commit SHA must match the action&#39;s current reference, this drift causes the workflow to fail before any job starts [1][4]. To resolve this mismatch, you must regenerate the lockfile using the gh-actions-lock CLI [1][4]: 1. Run the standard update command to re-resolve references and update the lockfile: gh actions-lock --relock [1] 2. If the mismatch involves refs that have moved or are considered suspicious, you may need to use the --accept-moved flag to force re-resolution [1]: gh actions-lock --relock --accept-moved [1] 3. To audit or verify the current state without making changes, you can use the --no-fix flag, which will fail if the workflow references do not match the recorded SHAs in the lockfile [4][6]: gh actions-lock --no-fix [4][6] The lockfile provides security beyond simple SHA pinning by verifying that the SHA exists within the claimed repository and branch, which helps prevent impostor-commit attacks [1][2]. Manual editing of the lockfile is discouraged, as it is prone to errors that can render the file unparseable and break all workflows in the repository [4][5].

<title>github/gh-actions-lock</title> https://github.com/github/gh-actions-lock # github/gh-actions-lock A gh CLI extension that generates and verifies the GitHub Actions dependency lockfile, pinning every action your workflows use to an exact commit. - Stars: 21 - Forks: 2 - Watchers: 21 - Open issues: 3 - License: MIT License - Default branch: main - Created: 2026-04-22T04:45:53Z ## Languages - Go - Makefile - Ruby - Shell ## Topics - cli - dependency-pinning - gh-extension - github-actions - go - lockfile - security - supply-chain-security ## Top Contributors - nodeselector (30 contributions) - Steve-Glass (1 contributions) --- ## README # gh-actions-lock Lock your workflow dependencies. > [!WARNING] > **Technical Preview.** gh-actions-lock is pre-1.0 and under active development. The > lockfile format, command flags, and behavior may change without notice between > releases. Use it, file issues, and expect rough edges. ## Background gh-actions-lock is part of GitHub&`#39`;s Workflow Dependency Pinning effort. It gives repositories a lockfile that pins every workflow dependency to a verified commit, so what runs on the runner is exactly what you locked. Development is ongoing and behavior may still change. Contributions are welcome. See CONTRIBUTING.md to get started. ## Requirements Requires the `gh` CLI. Install it first, then install the extension: ```bash gh extension install github/gh-actions-lock ``` ## Usage Scan every workflow under `.github/workflows/` directory, pin each resolvable action to a SHA, and update the lockfile: ```bash gh actions-lock ``` After the initial run to onboard workflows, you will need to run `gh actions-lock` when: - A new workflow is created that has `uses` dependencies. - An existing workflow adds or removes `uses` dependencies. A full-directory run (`gh actions-lock` with no path arguments) also prunes lockfile entries for workflows that have been deleted from `.github/workflows/`, dropping any dependencies left orphaned by the removal. Scoped runs that name specific workflows never prune out-of-scope entries. Pins to branches or partial versions (e.g. `main`, `v4`) are trusted from the lockfile and not re-resolved on a normal run. To bump them to the current upstream commit, run: ```bash gh actions-lock --relock ``` `--relock` re-resolves refs that have legitimately moved and rewrites the lockfile to the new SHA. Suspicious pins whose recorded commit is no longer reachable upstream are left as errors — use `--accept-moved` to re-resolve those as well. ### Self repository actions (`$/…`) `uses: $/…` references an action or reusable workflow in the **same repository** as the defining file, resolved at the **running commit**. Because it always resolves to that repository&amp;`#39`;s running SHA it is **inherently pinned** — no lockfile entry is required, and it is valid anywhere a relative `./…` reference is: ```yaml steps: - uses: $/actions/my-action # same-repo action, inherently pinned jobs: call: uses: $/.github/workflows/reusable.yml # same-repo reusable workflow ``` A trailing `@ref` (e.g. `$/actions/my-action@v1`) is rejected — the ref is always the running commit. Same-repo `./…` composite action references are automatically converted to `$/…` on fix runs. This rewrites `./…` steps both in your workflows and in your in-repo composite action definitions (`action.yml`). Only `./…` paths that resolve to an in-repo action file are rewritten. To leave `./…` refs untouched, opt out with `--no-migrate-local-actions`: ```bash gh actions-lock --no-migrate-local-actions ``` ## How it works A repo gets a lockfile (located at `.github/workflows/actions.lock`) and workflows are onboarded to the lockfile on a per-workflow basis. Workflows that are onboarded to the lockfile enforce that all dependencies are present in the lockfile and guarantees that the locked commit for an Action is what&`#39`;s executed on the runner. Lockfiles are also verified for forgeries. The sha must exist in the refs it&`#39`;s stated to exist in. Repository identity is recorded and redi…[truncated] <title>A trust checklist for GitHub Actions</title> https://jessehouwing.net/a-trust-checklist-for-github-actions/ ### Action lock files ... `gh-actions-lock` is a `gh` CLI extension, part of GitHub&`#39`;s Workflow Dependency Pinning effort. It produces a lockfile at `.github/workflows/actions.lock` that pins every workflow dependency to a verified commit. ... ```bash gh extension install github/gh-actions-lock gh actions-lock # scan workflows, pin, write the lockfile gh actions-lock --relock # re-resolve refs that have legitimately moved ``` ... The important point is that this is not merely SHA pinning with extra steps. The lockfile carries verification that a bare SHA in a `uses:` line cannot: ... - Onboarded workflows enforce that every dependency is present in the lockfile, and that the locked commit is what executes on the runner. - Lockfiles are verified against forgery: the SHA must exist in the refs it claims to exist in. - Repository identity is recorded, and redirects or mismatches are blocked at runtime. - A locked action must have a branch containing the locked commit, which makes impostor-commit attacks considerably harder. ... That last point deserves emphasis. A raw SHA in a workflow file offers no protection against an impostor commit — a commit pushed to a fork, which remains reachable through the upstream repository&`#39`;s object store and therefore resolves successfully. It looks entirely legitimate in a `uses:` line. The lockfile&`#39`;s reachability check is what closes that gap. ... Do note that the extension is a technical preview and pre-1.0; the lockfile format and flags may change. ... , and it ... a floating tag ... a practice it has ... - It destroys readability.`uses: some-org/some-action@a1b2c3d…` conveys nothing. The version has to be carried in a trailing comment, which nothing validates and which drifts from reality over time. - It is per-reference. Every workflow file must be maintained individually, rather than governed by one lockfile. - It offers no verification. As above, a SHA alone does not prove the commit belongs to the repository&`#39`;s history. ... A lock file gives you the same guarantee with better ergonomics and meaningfully stronger verification. Immutable releases give you upstream guarantees that need no consumer-side maintenance at all. <title>github/actions-lockfile</title> https://github.com/github/actions-lockfile # github/actions-lockfile The authoritative definition of the GitHub Actions dependency lockfile format, plus a Go parser for auditing and verifying the action pins in use across a repo&`#39`;s workflows. - Stars: 10 - Forks: 1 - Watchers: 10 - Open issues: 4 - License: MIT License - Default branch: main - Created: 2026-04-09T21:54:20Z ## Languages - Go - Makefile - Shell ## Topics - actions - dependency-pinning - github-actions - go - lockfile - security - supply-chain-security ## Top Contributors - nodeselector (13 contributions) --- ## README # actions-lockfile > [!NOTE] > **Public preview.** This project is pre-1.0 and under active development.

The lockfile records the resolved transitive dependency graph for a repository&`#39`;s workflows so tools can audit and verify the exact action pins in use. ## Background This project provides the shared, authoritative lockfile format that GitHub Actions tooling uses to record and verify resolved dependency pins. It is part of GitHub&`#39`;s broader Workflow Dependency Pinning effort, and the schema and parser will continue to evolve toward a stable `v1.0.0`. Contributions are welcome — see CONTRIBUTING.md. ## Installation ```sh go get github.com/github/actions-lockfile/go/pkg/lockfile ``` The Go module lives under `go/` so the repository can grow additional language bindings around the same lockfile schema. ## Usage ### Parse a lockfile and look up a workflow&`#39`;s pins ```go package main import ( "fmt" "os" lockfile "github.com/github/actions-lockfile/go/pkg/lockfile" ) func main() { contents, err := os.ReadFile(lockfile.Path) // ".github/workflows/actions.lock" if err != nil { panic(err) } file, err := lockfile.Parse(contents) if err != nil { panic(err) } pins, ok := file.LookupWorkflow(".github/workflows/release.yml") if !ok { fmt.Println("workflow not present in lockfile") return } for _, key := range pins { fmt.Println(key) // e.g. actions/checkout@v6.0.2 } } ``` ### Surface structured parse errors `Parse` returns a `*lockfile.ParseError` carrying line and column for semantic failures, so callers can anchor diagnostics on the lockfile itself instead of scraping yaml.v3&`#39`;s error string. ```go file, err := lockfile.Parse(contents) if err != nil { var perr *lockfile.ParseError if errors.As(err, &perr) { fmt.Printf("%s:%d:%d: %s\n", lockfile.Path, perr.Line, perr.Column, perr.Msg) return } panic(err) } _ = file ``` ## Schema The lockfile is a YAML document whose shape is defined by a JSON Schema 2020-12 document embedded in the package and reachable via `lockfile.Schema()`. The current schema version is `v0.0.2` (`schema/lockfile-v0.0.2.json`). The on-disk file lives at `Path` (`.github/workflows/actions.lock`) and has three top-level keys: ```yaml version: v0.0.2 workflows: # workflow path -> flat, transitive list of pin keys .github/workflows/release.yml: - actions/checkout@v6.0.2 dependencies: # pin key -> resolved action metadata actions/checkout@v6.0.2: ref: v6.0.2 commit: sha1-de0fac2e... owner_id: 44036562 repo_id: 197814629 ``` A pin key is `OWNER/REPO@REF`. The same key appears in both `workflows` (as flat transitive lists) and `dependencies` (as deduplicated graph entries with `uses:` links to direct dependencies). The parser also reads v0.0.1 lockfiles (which used `tag`/`branch` fields and `:algo-hex` suffixed pin keys) and normalizes them to the v0.0.2 `File` struct. Use `ParseWithPolicy` with a `VersionPolicy` to control which versions are accepted. ## Compatibility and stability - The Go module follows semver.

`actions.lock` is authoritative: the workflows carry readable refs and the lock records the
commit each ref resolves to, which is what actually runs. Refs that stop matching the manifest
make the whole repository unstartable — `startup_failure`, "Invalid lockfile".

Regenerated with the official extension (`github/gh-actions-lock`). The hand-pinned SHA refs are
reverted to their readable form here precisely because the lockfile, not the workflow, is what
pins them.

…s and ecosystem recon (#73)

Two logically separate pieces of work on one branch, because this
session is
pinned to a single branch. **Part 1** finishes the tail end of #67.
**Part 2** is
a recon pass that found the repository's documentation describing a
project it
is not, and fixes that. Part 2 is the larger half; Part 1 is two lines.

---

# Part 1 — `fix(rust)`: clear the rust-core Clippy gate

At `main` = `e1b6225` the `Rust core (tests, formatting, lint)` job
passed `cargo
fmt` and `cargo test` (6/6) and failed at Clippy with exactly two lints,
both in
`rust/pdftool_core/src/lib.rs`.

```diff
 fn resolve_object(doc: &Document, obj: &Object) -> Result<Object, lopdf::Error> {
     match obj {
-        Object::Reference(id) => doc.get_object(*id).map(Clone::clone),
+        Object::Reference(id) => doc.get_object(*id).cloned(),
         _ => Ok(obj.clone()),
     }
 }

 fn object_to_number(obj: &Object) -> Option<f32> {
     match obj {
         Object::Integer(v) => Some(*v as f32),
-        Object::Real(v) => Some(*v as f32),
+        Object::Real(v) => Some(*v),
         _ => None,
     }
 }
```

1. `clippy::map_clone` → `.cloned()`. lopdf 0.34's
   `Document::get_object(&self, id) -> Result<&Object>` [^1], and
`Result<&T, E>::cloned() -> Result<T, E> where T: Clone` is stable since
Rust 1.59.0 [^2]. `Object` derives `Clone`, so the declared return type
   `Result<Object, lopdf::Error>` is unchanged.
2. `clippy::unnecessary_cast` → `Some(*v)`. `Object::Real(f32)` [^3], so
`v`
   is `&f32` and the cast was an identity cast.

The adjacent `Object::Integer(v) => Some(*v as f32)` is **deliberately
left
alone**: `v` is `&i64` there and that `i64` → `f32` cast is real. Clippy
did not
flag it.

## Local verification

**There is no Rust toolchain in this sandbox and no crates.io access, so
`cargo fmt --check`, `cargo test --locked` and `cargo clippy` were not
run
here.** `cargo` and `rustc` are absent, `~/.cargo` and `~/.rustup` do
not exist,
and `static.rust-lang.org`, `sh.rustup.rs`, `crates.io` and `docs.rs`
are all
network-blocked (`SSL_ERROR_SYSCALL`); only `github.com` /
`api.github.com` are
reachable. The two edits were verified by reading the upstream source of
the
exact pinned dependency:

- `lopdf` 0.34.0 (the `Cargo.lock` version): `get_object` returns
  `Result<&Object>`, and `Object` is `#[derive(Clone, PartialEq)]` with
  `Real(f32)` — fetched from the `v0.34.0` tag via the GitHub API.
- `std`: `impl<T, E> Result<&T, E> { pub fn cloned(self) -> Result<T, E>
where
T: Clone }`, `#[stable(feature = "result_cloned", since = "1.59.0")]` —
the
doc example is literally `Result<&i32, i32>::cloned() -> Result<i32,
i32>`.
- `rust-clippy` master, `clippy_lints/src/methods/map_clone.rs`: for a
non-`Copy` `T` the suggestion is `cloned()` (vs `copied()` for `Copy`),
and
  the diagnostic is `Applicability::MachineApplicable`.

Against run 36296845297 (push, `e1b6225`, actor `hyperpolymath`), job
`Rust core (tests, formatting, lint)`, conclusion `failure`, the
step-level
results were:

| Step | Result |
| --- | --- |
| Check formatting (`cargo fmt --manifest-path
rust/pdftool_core/Cargo.toml -- --check`) | success |
| Run unit tests (`cargo test --manifest-path
rust/pdftool_core/Cargo.toml --locked`) | success |
| Run Clippy (`cargo clippy --manifest-path rust/pdftool_core/Cargo.toml
--locked --all-targets -- -D warnings`) | failure |

`rust/pdftool_core/src/lib.rs` is the crate's only `.rs` file, and
`grep -rn "map(Clone::clone)" rust/` now returns nothing, so
`--all-targets`
has no other file to fail on.

`docs/ci/CHECK-DETERMINATIONS.adoc` — the `rust-core` row said the job
had
never executed. It has: run 36296845297 reached its third step. The row
now
records fmt+tests green, the two lints, and this repair, and stays open
pending
one owner-triggered green run on `main`. It is **not** marked plain
"Fixed",
because no such run exists yet.

# Part 2 — recon: the docs were describing a different project

## What was wrong

Six documents were materially out of date, in the way that makes a
reviewer say
*"oh, wait"*:

| File | What it said | What is true |
| --- | --- | --- |
| `.github/CONTRIBUTING.md` | Cloned `hyperpolymath/language-bridges`;
documented a `lib/` + `extensions/` + `plugins/` + `tools/` layout; told
readers to run `just check`, `mix compile`, `guix develop`; referenced
an issue template that did not exist | None of that exists here. Repo
uses `Justfile`, `.adoc` docs, one Rust crate and an AffineScript
prototype |
| `TOPOLOGY.adoc` | "Deno-first scripts"; Popup UI 100% "stateful forms
stable"; overall "~90% Production-ready extension" | `deno.json` deleted
by #43; the frontend is a prototype with no build pipeline |
| `EXPLAINME.adoc` | Listed **Deno** as a technology choice; mapped a
`lib/` directory | Deno is gone; the core is Rust + lopdf |
| `www/.well-known/humans.txt` | "Components: Idris2 ABI, Zig FFI",
dated 2026-03-28 | Rust/WASM + AffineScript prototype |
| `REQUIRES_INITIALISATION.adoc` | "10 substitution tokens across 3
files" | 8 live tokens in 2 files; the 2 said to be in
`CODE_OF_CONDUCT.md` were already resolved |
| `docs/tech-debt-2026-05-26.adoc` | "CHANGELOG.md is missing",
"CONTRIBUTING.md Y" | `CHANGELOG.adoc` exists; `CONTRIBUTING.md` existed
and was wrong |

Plus three structural gaps: **no issue templates at all**, **no PR
template**,
and **no wiki** (the wiki feature is enabled but `.wiki.git` had never
been
initialised).

## What changed

**Corrected** — `CONTRIBUTING.md` (rewritten against this repo),
`TOPOLOGY.adoc`
(dashboard, missing "Last updated" date, and a rule-of-honesty note that
a bar
describes working verified code rather than files on disk),
`EXPLAINME.adoc`
(real dependency set plus a claims-and-where-they-are-checked table),
`www/.well-known/humans.txt` and `ai.txt` (the latter pointed at an
`AI.a2ml`
that does not exist), `TEST-NEEDS.adoc` (14 workflows not 15, stale
header),
`CHANGELOG.adoc` (the `[Unreleased]` section was a mangled commit dump
with a
duplicated line and an inline `-Authored-By:` trailer), and a new
status-as-of-2026-09-27 section on the tech-debt snapshot so it cannot
be
mistaken for current state.

**Added** — `docs/ecosystem/ECOSYSTEM.adoc`, the suite boundary
statement; an
*Ecosystem position* section in `README.adoc`; `.github/ISSUE_TEMPLATE/`
(`bug_report.yml`, `feature_request.yml`, `documentation.yml`,
`config.yml` in
the estate's YAML form style); `.github/PULL_REQUEST_TEMPLATE.md`; and
`wiki/` plus the live wiki.

**Machine-readable state** — `INTENT.contractile`'s eight outstanding
tokens
filled from evidence, along with its empty `architectural-invariants`
and
`ask-before-touching` placeholders; `methodology.a2ml`'s
`unique-strength`, `divergent-invariants` and `known-constraints`
filled;
`STATE.a2ml` given `verified` / `not-implemented` / `known-red-on-main`
/
`open-decisions` sections (its `completion-percentage` had read `0`
since the
2026-03-15 conversion); `debt.a2ml` populated with the eleven things
this recon
found and deliberately did not fix; `0-AI-MANIFEST.a2ml` given a
read-in-this-
order list and a "three things that will surprise you" section.

Nothing was invented. Every token value is traceable to a file in this
repository or to docmatrix#71, and `REQUIRES_INITIALISATION.adoc` —
rewritten as
a resolution record rather than deleted — says which is which.

## The wiki

Seeded in **BerryWiki** format, the design taken from the
metadatastician
estate: a hidden `<!-- berrywiki … -->` metadata block carrying `id`,
`parent`,
`position`, `kind` and `tags`; hierarchy from the `parent` id chain
rather than
filenames; a generated `_Sidebar.md`; plain Markdown that renders
natively in
GitHub's wiki reader with or without BerryWiki; zero JavaScript.

Eight pages: Home, Architecture, Rust-Core, CI-and-Gates, Ecosystem,
Contributing, Contributing--Dev-Setup, Glossary. Structure validated
programmatically — 8 pages, unique ids, every `parent` resolves, sibling
positions distinct, no broken `[[WikiLinks]]`, every `_Sidebar` link
resolves.

The source lives in `wiki/` so it is versioned and reviewable; the
published
mirror has been pushed to `hyperpolymath/blocky-writer.wiki.git` (commit
`59b17bd`, replacing the placeholder "Welcome to the blocky-writer
wiki!"
page). `wiki/README.adoc` documents the format, the three rules that
make it
work, the publish step, and how to add a page.

# Owner actions

1. **Merge as yourself, not via the bot.** Every Actions run triggered
by
   `arena-ai-coding-agent[bot]` in this org is refused at startup with
`Actor is not allowed to trigger Actions workflows`, so this PR will
show
**no repository checks at all** — not red, absent — because a startup
failure
creates no check run. That is expected and is not a signal about this
branch;
   it is the same org-side policy recorded in
`docs/ci/CHECK-DETERMINATIONS.adoc` (<<actor>>) that stopped #71's runs.
Nothing was weakened to work around it: no `continue-on-error`, no `if:
false`,
   no demotion.
2. **Once CI is green on `main`, add two required status checks to the
`Branch-Floor` ruleset** (id 23869449, target `~DEFAULT_BRANCH`,
currently
carrying only `deletion` and `non_fast_forward` — verified via the API,
it
   has no `required_status_checks` rule):
   - `actions.lock is in sync with the workflow YAML`
   - `Rust core (tests, formatting, lint)`
3. **Tick "require branches to be up to date"** on that ruleset.

Until step 2 lands, rule 2 of the standing rules in
`docs/ci/CHECK-DETERMINATIONS.adoc` ("a red Lock Sync Gate is never
merged
over") is a convention rather than an enforcement. Note the intended
interaction with the actor refusal: a required check that never runs
blocks
every bot-authored PR from merging, which is the correct outcome — it
turns
"CI-silent merge" into "cannot merge until an allowed actor triggers
CI".

Optional, and cheap: update the repository **description and topics** to
match
the boundary statement. The topics are currently
`automation, cli-tool, developer-tools, epistemic-computing,
epistemic-infrastructure, equivalence-aware-computing, hyperpolymath,
open-source, rust, typed-provenance, veridical-computing` — none of
which say
pdf, firefox-extension, wasm, affinescript or document-suite.

# Cross-repo issues — filed

Eleven short issues, one per neighbour. Each says where blocky-writer
is, what
they can now progress with, and what they might use from here. None
proposes an
integration; that was deliberate — the ask was for parallel
communication, not a
remarkable integration exercise.

| Repo | Issue | Gist |
| --- | --- | --- |
| `docmatrix` |
[#79](hyperpolymath/docmatrix#79) | **#71
acceptance criterion 1 is met on our side** — README boundary statement
+ `docs/ecosystem/ECOSYSTEM.adoc`. Asks them to confirm the wording and
to decide whether the GitHub *description* also needs it. |
| `formatrix-docs` |
[#61](hyperpolymath/formatrix-docs#61) |
Boundary declared: viewer/editor stays theirs, placement stays ours.
Notes the `detect_blocks` rectangle+label shape as a possible seam, and
offers our `.a2ml` files as parser test material. |
| `affinescript` |
[#771](hyperpolymath/affinescript#771) | **A
real consumer exists and is blocked on the on-ramp.** Eight `.affine`
files, none compilable — no compiler config, no bundle pipeline. Asks
for the smallest thing that makes them build. |
| `docudactyl` |
[#84](hyperpolymath/docudactyl#84) | Field
labels are our weak spot; forms with no `/T` get a meaningless
`field_<page>_<index>`. OCR is the obvious fix. Offers our widget
rectangles in return. |
| `dotmatrix-fileprinter` |
[#83](hyperpolymath/dotmatrix-fileprinter#83)
| Sibling check-in. No seam identified; asks them to confirm either way
so it is recorded rather than rediscovered. |
| `presswerk` |
[#118](hyperpolymath/presswerk#118) | A filled
application form is a print job. Notes that nothing currently
distinguishes a machine-filled form from a hand-filled one, and asks
whether that should be deliberate. |
| `universal-language-server-plugin` |
[#96](hyperpolymath/universal-language-server-plugin#96)
| Flags a possible conversion-boundary overlap with docmatrix rather
than letting it be resolved by whoever writes code first. |
| `recon-silly-ation` |
[#68](hyperpolymath/recon-silly-ation#68) |
Clause 4 (never silently normalise) is the invariant we are most likely
to break. Asks where reconciliation ends and silent normalisation
begins. |
| `berrywiki` |
[#61](metadatastician/berrywiki#61) | **A real
wiki now runs the format.** Includes the honest caveat that `berrywiki
check` could not be run here (no Rust toolchain), so our seed is
validated by our own script, not theirs. |
| `gv-clade-index` |
[#96](hyperpolymath/gv-clade-index#96) |
`CLADE.a2ml` entry check. Phase `active` is correct but may overstate
the project; asks whether a "core works, product incomplete" bucket
exists. |
| `rsr-template-repo` |
[#200](hyperpolymath/rsr-template-repo#200) |
**Template bug:** the shipped `CONTRIBUTING.md` told readers to clone
`hyperpolymath/language-bridges`. Plus the stale token count in
`REQUIRES_INITIALISATION.adoc`. |

Not filed, deliberately: `standards` and `deed-ecosystem`. The
actor-refusal
signature is already recorded estate-wide (the determinations doc cites
`wordpress-tools#96` and `statistikles#112`), so a third report would
add noise
rather than signal.

# Follow-ups noted, not fixed

* **Two workflows build the Pages site under one concurrency group.**
  `pages.yml` (Ddraig SSG, Idris 2) and `casket-pages.yml` (casket-ssg,
Haskell) both build and deploy to `github-pages`, so they cancel each
other.
`pages.yml` also looks for `README.md`, which does not exist here — it
would
publish a bare `# hyperpolymath/blocky-writer` index. `casket-pages.yml`
handles `README.adoc` correctly. **Which one is canonical is undecided,
and it
is an owner call.** Any fix needs the matching `actions.lock` change in
the
  same commit.
* **Two other checks are red on `main` at `e1b6225`, unrelated to this
PR.**
Neither touches the Rust crate and neither has a row in the
determinations
  ledger, so both need one before anything is done about them:
  - `Hypatia Security Scan` (run 36296845360) — the
`Hypatia Neurosymbolic Analysis` job fails at `Build Hypatia scanner (if
    needed)` and `Upload SARIF to GitHub code scanning`.
  - `Mirror to Git Forges` (run 36296845635) — 4 of 7 mirror jobs fail
(`mirror-disroot`, `mirror-gitea`, `mirror-codeberg`,
`mirror-bitbucket`);
`mirror-gitlab`, `mirror-sourcehut` and `mirror-radicle` are green, so
this
looks like per-forge credential or host reachability rather than a
workflow
    defect.
  - Both were already red at `a94b5b5`, i.e. before this branch existed.
* **Orphaned build leftovers.** A ~90 KB `deno.lock` sits in the root
although
#43 deleted `deno.json`; `webpack.config.cjs` configures a bundle
pipeline
that does not exist. Both are the most likely things to make a reviewer
think this is a Deno project. Deleting them is safe but it is an owner
call —
  an estate tool outside this checkout may reference them.
* **`Justfile` reads a file that does not exist.** The `crg-grade` and
`crg-badge` recipes parse `READINESS.md`; the CRG grade actually lives
in
  `TEST-NEEDS.adoc`. Both silently fall back to grade `X`.
* **The product gap.** Ruled-line, per-character-cell and baseline
detection are
not implemented. `detect_blocks` reports widget annotation rectangles
only.
This is the "hand spacing" case the project is named for — the real
thing to
  build next, and deliberately left alone here.
* The `rust-core` row in `docs/ci/CHECK-DETERMINATIONS.adoc` should be
  re-marked *Fixed* once an owner-triggered green run on `main` exists.
* The `ubuntu-latest` label migrates to Ubuntu 26 on 2026-10-19
(runner-images
  issue 14748), per the notice on run 36296845297.
