📝 Walkthrough

Walkthrough

The repository shifts from Go scaffolding to a Bun and TypeScript project. It adds a Bun CLI, filesystem and devcontainer discovery APIs, schema validator generation, schema provenance, and schema-drift automation. CI and project configuration now use Bun tooling.

Changes

Bun and TypeScript project transition

Layer / File(s) Summary
Bun project setup and CLI
.github/workflows/ci.yaml, .gitignore, .golangci.yml, .prettier*, .vscode/*, CLAUDE.md, Makefile, README.md, bunfig.toml, cmd/dcx/main.go, go.mod, index.ts, package.json, tsconfig.json
The package manifest, TypeScript settings, Bun CLI, formatting and editor configuration, and Bun CI commands are added. The Makefile and Go build and lint configuration are removed. The README and Bun guidance describe Bun commands and usage.
Filesystem contract and implementations
src/vfs/*
A FileSystem contract, BunFS, and OverlayFS are added. Tests cover file operations, metadata, symlinks, sorted listings, and overlay behavior.
Devcontainer discovery
src/discovery/*
discoverDevcontainer handles file targets and searches preferred configuration paths and immediate .devcontainer subdirectories. Tests cover lookup order, missing targets, searched paths, and overlay buffers.
Schema provenance and drift automation
.github/workflows/schema-drift.yaml, .gitmodules, devcontainer-spec, schemas, scripts/build-validators.ts, src/schema/*
The schema submodule and schema symlink are added, with provenance records and a script that generates Ajv validators. Tests cover validator behavior and provenance. The workflow checks upstream for schema changes and opens a pull request when the pinned commit differs.
Go implementation and documentation removal
docs/DESIGN.md, extensions/vscode/.gitkeep, pkg/*, testdata/.gitkeep
The Go design document, package declarations and documentation, and position implementation and related test and fixture content are removed.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to 21818

The move to Bun is mostly in place. The main CI test job still fails on a fresh checkout because the schema submodule is not fetched, so the schema tests cannot find the schema files. Several earlier concerns also remain open: the CLI exits successfully for commands it does not implement, and the generated validator ignores URI format constraints. Fix these, or explicitly accept them, before merging.

In @.github/workflows/ci.yaml:
- Line 41: The Build step is empty because `run: bun ci` starts a separate step.
Update the workflow step structure so the Build step runs `bun run build`, and
place `bun ci` in its own step.
- Line 42: Update the build step in the CI workflow to pass each build leg’s
matrix target to `bun run build`, mapping `amd64` to Bun’s `x64` target name
while preserving other target names.
- Line 67: Add `bun ci` after Bun setup in the test job so its fresh checkout
installs dependencies before `bun run format:check` runs.
- Line 71: Update the condition on the bun test step so it runs on the Ubuntu
coverage matrix entry even when race is true, ensuring coverage/lcov.info exists
for the following Codecov step; preserve the existing behavior for other matrix
entries.

In @.vscode/extensions.json:
- Line 2: Update the recommendations list in the VS Code extensions

In `@package.json`:
- Around line 14-17: Add a typecheck script alongside the build script in
package.json that runs tsc --noEmit, then invoke that script in the CI workflow
after dependency installation.

In `@scripts/build-validators.ts`:
- Line 42: Add ajv-formats as a dependency and register it on ajv2019 before
compiling baseSchema in scripts/build-validators.ts, so the generated base
validator enforces its format: "uri" constraints. Keep the registration scoped
to the base validator; do not change feature schema validation.

In `@src/schema/schemas.test.ts`:
- Line 25: Update the schema file discovery in schemas.test.ts to handle a
missing schemas submodule before calling readdirSync, using the same skip

Give the Build step a command.

Line 41 starts a new step. The preceding - name: Build is therefore an empty step, which makes the workflow invalid before any job runs. Attach run: bun run build to the named step, and give bun ci its own step. The supplied actionlint result identifies the same error. (docs.github.com)

Compile for the target named by each build leg.

Every build leg uses ubuntu-latest, and bun run build supplies no --target. All six legs therefore compile for the Linux runner instead of validating their named OS and architecture. Map amd64 to Bun’s x64 target name and pass the matrix target to the build command. (bun.sh)

Install dependencies in the test job.

Each test leg has a fresh checkout, but only the build job runs bun ci. The format step invokes the locally declared Prettier executable before any test-job install, so it cannot rely on node_modules/.bin/prettier. Add bun ci after Bun setup in this job. (bun.sh)

Run the configured TypeScript check in CI.

bun run build bundles index.ts but does not type-check it or the new modules under src/. Add a typecheck script that runs tsc --noEmit, then invoke it in CI after dependency installation. Bun explicitly does not use its bundler as a TypeScript type checker. (bun.sh)

Based on learnings, confirm a clean TypeScript compiler run before treating TypeScript changes as complete.

Register URI format validation for the base schema.

The base schema applies format: "uri" to $schema and secret documentationUrl. The generated base validator checks only that these values are strings because ajv-formats is not registered. Therefore, a valid image such as {"image":"example","$schema":"not a uri"} can pass validation.

Add ajv-formats to the dependencies and register it on ajv2019 before compiling the base schema. Scope this change to the base validator; the feature schema’s documentationURL and licenseURL fields are string-only and do not use format: "uri".

Sensitive Data Exposure

Reachability: External
Exploitability: Moderate
CWE: CWE-522 — Insufficiently Protected Credentials

Disable persisted checkout credentials in all three jobs.

actions/checkout@v4 persists the read-scoped token before these jobs run dependency installation and repository code. Set persist-credentials: false on each checkout step. The workflow commands, package scripts, and lockfile do not require authenticated Git access.

Disable credential persistence
       - uses: actions/checkout@v4
+        with:
+          persist-credentials: false

Apply this change to all three checkout steps.

each of the three actions/checkout@v4 steps in the workflow, ensuring none of
the jobs retain the checkout token before running dependency installation or

Initialize the schema submodule before running tests.

actions/checkout@v4 does not fetch submodules by default. The tracked schemas symlink points into devcontainer-spec, but src/schema/schemas.test.ts calls readdirSync(schemasDir) without a skip condition. The test job therefore fails on a fresh checkout; the current Ubuntu and macOS checks report a failure at that read. Add submodules: true to this job’s checkout step. (github.com)

In @.github/workflows/ci.yaml at line 38, Update the test job’s
actions/checkout@v4 step to fetch submodules by enabling submodule checkout, so
the schemas symlink target exists when bun test runs.
