J3vbandClaude Opus 5 2a37f386f9 B1-3: repository hygiene gates (RL-19 / L-13, S-05) (#1414)
* chore(format): one Prettier config at the repository root

Every formatting rule in this repository lived under Client/ and covered
exactly two globs: Client/src/**/*.ts and Client/tests/**/*.ts. Root Markdown,
all of docs/, every YAML and JSON, all CSS, the root scripts and
tools/mcp-introspect were formatted by nothing. There was no .editorconfig.

The obvious fix -- a second Prettier config at the root for "everything else"
-- gives two configs and two ignore files that can silently disagree about the
same file. So the root takes ownership instead: config, ignore file and gate
move up, and Client/ folds in. Client's inline "prettier" block, its
.prettierignore, its format/format:check scripts and its now-unused prettier
devDependency are all deleted; knip would have failed client-check on that last
one.

The .prettierrc.json values are lifted byte-for-byte from Client/package.json,
which is what keeps the reformat commit free of client TypeScript churn: 87
tracked files need reformatting and not one of them is under Client/src or
Client/tests.

.prettierignore carries only what .gitignore does not. Prettier 3 reads the
root .gitignore by default, so node_modules/, dist/, coverage/,
Client/src/generated/ and docs/security-findings/ need no entry. It does NOT
read nested .gitignore files, which is why .remember/ is listed explicitly --
38 untracked per-machine scratch files were otherwise able to turn a shared
gate red. graphify-out/ is listed because its seven files are tracked and
.graphify_labels.json is signed byte-for-byte by its .sig, so formatting it
would silently invalidate the signature.

check:hygiene is registered in scripts/run.mjs and folded into check and
release:preflight. It deliberately contains no `gofmt -l` step: gofmt -l prints
offenders and still exits 0, so it cannot fail a build. Go formatting is
enforced separately.

shellcheck and actionlint take their file lists from `git ls-files`, never a
filesystem glob -- .claude/worktrees/ holds a gitignored pre-flatten copy of
the tree with three .sh files a glob would happily lint.

This commit leaves the tree non-conformant on purpose. The reformat is the next
commit, so the 87-file diff is reviewable separately from the rule that caused
it.

Not included: editorconfig-checker. .editorconfig is the editor baseline the
audit asked for; Prettier, gofmt and rustfmt already fail CI on the same
indentation and newline rules, so a fourth tool checking them again is a gate
with no failure mode of its own.

Verified: `npx prettier --check .` names 87 tracked files and zero untracked
ones; the same command listed 38 .remember/ scratch files before the ignore
entry and none after. `node scripts/run.mjs --list` resolves check:hygiene to 8
shell targets and 4 workflow targets. Both package.json files parse.

* chore(format): reformat the tree to the repository Prettier rules

Mechanical. This commit is `npx prettier --write .` and nothing else -- the
rule that caused it landed in the previous commit so this diff can be reviewed
as a transformation rather than as 84 files of hunks.

84 tracked files: 54 Markdown, 7 .mjs, 7 JSON, 6 YAML, 4 .js, 3 CSS, 2
TypeScript (the two Playwright configs at Client's root, which the old
Client/src + Client/tests globs never covered). No file under Client/src or
Client/tests moves, because .prettierrc.json carries Client's former inline
values byte-for-byte.

Prettier rewrote 87 files, not 84. The three in .github/ISSUE_TEMPLATE/ had
CRLF on disk and differ only in line endings, which .gitattributes
(`* text=auto eol=lf`) already normalises, so their committed blobs are
unchanged. Worth knowing before someone reconciles the two numbers.

The largest single diff is .superpowers/findings-ledger.json at 7976 lines
rewritten. That is safe to format: nothing writes the ledger programmatically
-- render-ledger.mjs reads it and writes only FINDINGS.md -- so no tool will
fight Prettier over its style on the next hunt. FINDINGS.md itself is ignored
as generated.

Verified: `npx prettier --check .` reports "All matched files use Prettier code
style", so the pass is both complete and idempotent. All 7 reformatted JSON
files were parsed before and after and compared as values: semantically
identical, zero content changes. `node .superpowers/render-ledger.mjs --check`
still reports 348 valid findings and leaves FINDINGS.md untouched.
`node scripts/check-doc-counts.mjs` still passes its selftest and still agrees
on 27 claims across 9 watched documents -- table realignment did not break the
patterns it matches on. `node scripts/run.mjs --list` still parses.

* chore(lint): enforce Go formatting in the Server linter

S-05: repository-wide Go formatting was not a required gate. The only gofmt
enforcement anywhere was .githooks/pre-commit, which is opt-in per clone
(`npm run hooks:install`), only sees staged files, and warns-and-skips when
gofmt is off PATH.

The obvious fix -- a `gofmt -l` step in CI -- does not work: `gofmt -l` prints
its offenders and still exits 0, so the step passes no matter what it finds.
scripts/run.mjs has the same problem, which is why check:hygiene has no Go step
either.

So gofmt goes where it can actually fail something: Server/.golangci.yml. The
file was already `version: "2"` but had no `formatters:` block at all, so the
19 enabled linters ran with zero formatters. In v2 gofmt/gofumpt/goimports
moved out of `linters.enable` into their own section with its own exclusions.
Adding it there means the gate reports through the Lint step of "Server Build &
Test", which is already pinned as required on dev -- no new job and no new pin.
Every tracked .go file is under Server/ (551 of them, one go.mod), so
Server-scoped is repository-wide here.

One file was genuinely misformatted: a one-space struct field alignment in
Server/admin/handlers_users_broadcast_test.go, fixed in the same commit because
a single line does not need its own reformat commit.

Trap worth recording: `gofmt -l .` on a Windows working tree lists every file
that has CRLF on disk, because gofmt normalises line endings. That reported 18
offenders here, 17 of them ghosts. The blobs are all LF -- .gitattributes
forces `eol=lf` -- so CI never saw them, and the honest test is to run gofmt
over `git show HEAD:<file>` rather than the working copy. Doing that across all
551 tracked Go files found exactly the one real offender above.

Verified both directions with golangci-lint v2 locally: `golangci-lint run
./...` reports 0 issues on the formatted tree; appending a misformatted
function to Server/auth/constants.go produces 2 gofmt findings; appending the
same misformatted function to Server/db/dbgen/admin.sql.go produces 0, so the
exclusion holds. Both files restored and verified clean afterwards.

* fix(scripts): escape the NUL separator instead of embedding one

The `tracked()` helper added earlier in this branch splits `git ls-files -z`
output on NUL. The separator was written as a literal NUL byte rather than the
two-character JavaScript escape, so scripts/run.mjs became a binary file: `git
diff` refused to show it, `grep` reported "Binary file matches" instead of the
line, and `* text=auto` in .gitattributes stops normalising line endings for a
blob it detects as binary.

The code worked -- splitting on a raw NUL and splitting on "\0" are the same
operation -- which is exactly why this is worth fixing before it is inherited.
A source file that tooling classifies as binary is a file nobody can review.

Verified: zero NUL bytes remain, `grep -n "split("` now prints line 50 instead
of "Binary file matches", `node scripts/run.mjs --list` still resolves the same
8 shell and 4 workflow targets, and prettier still reports the file clean.

* chore(lint): enforce Rust formatting

Rust had no formatting gate of any kind: no rustfmt.toml, no `cargo fmt`
anywhere in CI, in scripts/run.mjs, in the Makefile or in the git hooks. Clippy
was the only Rust gate, and clippy does not check layout.

`cargo fmt --all -- --check` now runs in the rust-tests job, ahead of clippy: a
formatting failure is cheap to produce and cheap to fix, and there is no reason
to spend a clippy pass to surface one. The stable toolchain in that job
requested `components: clippy` only, so rustfmt is added there.

Only that job. ci.yml has a second, byte-identical `Install Rust` block in
tauri-build; it stays clippy-only, because a full desktop build is the wrong
place to discover a misplaced brace.

No rustfmt.toml. The default profile is the point of a baseline -- a config
file here would be a second opinion about style with nothing to say.
Client/src-tauri is a single `[package]`, not a workspace, so `--all` is a
safeguard against a future member rather than a fan-out today.

Verified: `node scripts/run.mjs --list` resolves check:rust to three steps with
`cargo fmt --all -- --check` first, `npm run format` now also runs `cargo fmt
--all`, and prettier reports ci.yml, run.mjs and the ci-check skill clean.
`cargo fmt --all -- --check` currently fails on 13 files -- that is the
reformat, and it is the next commit.

* chore(format): reformat the Rust crate to rustfmt defaults

Mechanical. This commit is `cargo fmt --all` and nothing else; the gate that
demands it landed in the previous commit so this diff is reviewable on its own.

13 of the 17 tracked .rs files, +343/-164. The crate had never been formatted,
so the changes are the usual first-run set: aligned trailing comments collapsed
to single spaces, single-element slice literals folded onto one line, long
method chains broken across lines, closure bodies expanded into blocks.

Verified: `cargo fmt --all -- --check` is clean, so the pass is complete and
idempotent. `cargo clippy --all-targets -- -D warnings` finishes with no
warnings, and `cargo test --lib` reports 115 passed / 0 failed -- identical to
before the reformat, which is what "mechanical" has to mean for a commit that
touches this much of the crate.

* fix(scripts): make the root facade actually run on Windows

Adding the first gate that a contributor would run from the repository root
exposed two bugs in the facade, both of which made it silently wrong on the
platform this project is developed on.

1. Every npm and npx step failed. bin() appends `.cmd` on Windows, but Node
   refuses to spawn a .cmd or .bat with shell:false -- the CVE-2024-27980
   mitigation -- and fails with EINVAL and a *null* exit status. run.mjs only
   special-cased ENOENT, so the result was `FAILED: npx prettier --check .
   exited null` with nothing to explain it. check:client has three npm steps and
   has never been able to run here.

   Fixed by spawning only the npm shims through a shell. They are concatenated
   into a single command string rather than passed as an args array, because
   shell:true plus a separate array is deprecated (DEP0190) and prints a warning
   on every invocation; no argument in this file contains a space.

2. Every optional() step was skipped, always. onPath() shelled out to
   `where` on Windows, but where.exe lives in C:\WINDOWS\System32, which a Git
   Bash PATH does not necessarily contain -- on this machine PATH carries
   System32\Wbem, System32\WindowsPowerShell\v1.0 and System32\OpenSSH but not
   System32 itself. The probe could not start, `probe.status === 0` was false,
   and golangci-lint and sqlc reported as "not installed" while installed.

   Fixed by resolving against PATH and PATHEXT directly. No subprocess, and no
   dependency on which directories happen to be on PATH.

A spawn error other than ENOENT now reports its code instead of surfacing as a
null exit status.

Verified: before, `node scripts/run.mjs check:hygiene` died with "exited null"
and both optional steps printed SKIP with the tools present on PATH. After, the
same command runs prettier, shellcheck and actionlint and prints
"check:hygiene: passed", with no deprecation warning. `golangci-lint` is
detected by the new onPath where the old one missed it.

* chore(format): ignore build output that nested gitignores hide

Prettier honours the root .gitignore and no other. Every build and scratch
directory in this repository is ignored by a *nested* one -- Client/.gitignore,
.serena/.gitignore, .superpowers/sdd/.gitignore -- so none of them were
excluded from the new repository-wide gate.

The effect is not subtle. Running `cargo test` once drops roughly 850
formattable files into Client/src-tauri/target/, and the hygiene gate goes from
clean to "Code style issues found in 939 files". CI never sees it, because a
fresh checkout has no build output; every contributor sees it on their second
command.

Mirrors the three nested files rather than inventing a list: dist, coverage,
playwright-report, test-results, .vite, src-tauri/target and src-tauri/gen from
Client/.gitignore, plus .serena/ and .superpowers/sdd/. node_modules needs no
entry -- Prettier ignores it by default.

Verified: `npx prettier --check .` reports "All matched files use Prettier code
style" with a fully populated Client/src-tauri/target/ present on disk, and
still names README.md when a misformatted table is appended to it.

* chore(ci): shellcheck, actionlint, and a repository hygiene job

The last two gates RL-19 asks for. Neither existed: the shell scripts were
never linted, the workflows were never syntax-checked, and .githooks/pre-commit
carried hand-written `# shellcheck disable=` directives that nothing had ever
read.

New `hygiene` job, ubuntu-only and root-scoped, modelled on docs-consistency
for the same reason: every gate in it is platform-independent text analysis,
and .gitattributes pins eol=lf so a second OS would only re-prove line endings.
It runs `npm run check:hygiene` -- the same entry point a contributor runs, not
a parallel copy of the commands.

shellcheck ships in the runner image. actionlint does not, so it is pinned by
version and verified by sha256: an installer script piped from a branch would
be the one unverified download in a workflow file that pins every action by
commit SHA.

Prettier's step moves here from client-check, where it no longer belongs.

Both linters found real defects.

shellcheck, 3 findings in 8 scripts. Two are SC1125 errors in
.githooks/pre-commit: `# shellcheck disable=SC2086 - repo paths contain no
spaces` is not a valid directive. Trailing prose makes shellcheck discard the
rest of the line, so neither suppression was ever in effect -- and one of the
two was written earlier in this same branch, which is a fair demonstration of
why the gate is worth having. The prose moves to its own line above. The third
is SC2015 in start-server.sh, rewritten as an explicit if.

actionlint, 5 findings, all inside `run:` blocks it shellchecks once shellcheck
is on PATH. Three SC2015 in load-baseline.yml, rewritten as explicit ifs. Two
SC2035 in release.yml, where `sha256sum *` should not become `sha256sum ./*`:
the comment four lines above records that ParseChecksumFile exact-matches the
last field, so a "./" prefix would strand every deployed server exactly as a
"windows/" prefix would. `sha256sum -- *` satisfies the linter and leaves the
output bytes identical.

Verified all three gates in both directions with shellcheck 0.10.0 and
actionlint 1.7.7 on PATH. Passing: `node scripts/run.mjs check:hygiene` prints
"check:hygiene: passed" with all three steps run, not skipped. Failing:
appending `bait_fn() { cat $1; }` to Server/scripts/voice-test.sh fails on
SC2086; changing a runs-on to `ubunt-latest` fails on runner-label; appending a
misformatted table to README.md fails prettier. All three files restored and
confirmed clean afterwards. actionlint validates the new job in ci.yml itself.

* docs(plans): record B1 progress through B1-3

The header still read "B1-0 is complete; B1-1 is the next step" three merged
phases later. A plan that misstates where it is costs a reader the same
confusion whether it is stale by one phase or three.

B1-0 (#1410), B1-1 (#1411), B1-2 (#1412) and B1-3 (this branch) are done; B1-4,
dependency automation, is next.

Verified: `node scripts/check-doc-counts.mjs` still agrees on 27 claims across
9 watched documents -- this file is one of them -- and prettier reports it
clean.

* chore(ci): pin Repository Hygiene as a required check on dev

The second half of S-05. Its acceptance criterion is "tree is formatted AND a
fast required gate fails future drift" -- a check that runs but is not pinned
lets a formatting regression merge, so the gate is not a gate until this lands.

The name was read off PR #1414 with `gh pr checks` after the job reported
`pass` in 26s, not copied out of ci.yml. That order matters: the B0 script
records that three pinned names exist in no workflow file at all, and that a
required check which never reports blocks every PR forever.

Extends the existing script rather than adding a second one, per the B1 plan.

Also records, in the "deliberately NOT pinned" list, that Docs & Ledger
Consistency reports and passes on a dev PR yet is unpinned. That reads as an
oversight from the 2026-08-25 pass rather than a decision, but it belongs to
G-04, so it is documented here and not changed.

NOT APPLIED YET. Running this script now would pin a check that PR #1413 cannot
report -- its branch predates the hygiene job, so the job does not exist in its
workflow file and the check would never arrive. Run it after #1414 merges;
#1413 needs a rebase onto dev regardless.

Verified: shellcheck clean, the embedded JSON parses, and `check:hygiene`
passes with prettier, shellcheck and actionlint all running.

Contributing

How to set up the development environment and contribute to OwnCord.

Development Setup

Prerequisites

Platform Server Client
Windows 10+ x64
Linux x64
Linux ARM64 (CI only)
  • Go 1.26+ (server)
  • Node.js 24+ (client) — pinned in Client/.nvmrc; engine-strict makes a wrong major a hard failure, not a warning
  • Rust / Cargo (Tauri client — not needed for server-only work)
  • Docker + Compose v2 (optional — alternative to building the server locally)

Available Commands

Root facade — one entry point

From the repository root. These orchestrate the per-stack commands below; they are a convenience, not a replacement. Nothing here needs make, and everything works the same on Windows, macOS and Linux.

Command Description
npm run bootstrap npm ci in all three package roots
npm run check Everything CI gates on: server, client, Rust
npm run check:server Server only — build variants, vet, race, deadlock, lint, generated-output drift
npm run check:client Client only — typecheck, lint, format, unit + integration tests
npm run check:rust Tauri backend — cargo test --lib and clippy
npm run check:docs Fail if a watched document states a finding count the ledger contradicts
npm run format Prettier over the client, gofmt -w over the server
npm run generate Regenerate protocol constants and the sqlc query layer
npm run release:preflight check plus a client production build
node scripts/run.mjs --list Print the exact command every task runs, and where

Tools CI installs but you may not have — golangci-lint, sqlc — are skipped with a printed reason rather than failing the run.

Working on the server only? You never need Node. The facade prints each command it runs and the directory it runs it in; those are the commands in the next section, and using them directly is equally correct.

Server (Go)

Command Description
go build -o chatserver.exe -ldflags "-s -w" . Build server binary (Windows)
CGO_ENABLED=0 go build -o chatserver -ldflags "-s -w" . Build server binary (Linux)
go build -tags otel . Build with OpenTelemetry SDK (requires go get first — see Phase B)
go build -tags wazero . Build with Wazero plugin runtime (requires go get first — see Phase C)
go test ./... Run all server tests
go test ./... -cover Run server tests with coverage
go test -race ./... Run server tests with race detection

Make targets (run from Server/):

Command Description
make test Run the test suite the way CI does (-race, 20 min timeout)
make test-deadlock Run the deadlock-detection pass CI also runs (-tags deadlock)
make cover Per-package coverage (what CI uploads) + a function summary
make cover-all Cross-package coverage — the honest number (also lists 0.0% functions)
make sqlc-install Install the pinned sqlc version into $GOBIN
make sqlc-generate Regenerate the type-safe Go query layer (db/dbgen/, SQLite engine)
make sqlc-verify Fail if the committed dbgen output is stale (used by CI)
make protocol-generate Regenerate the WS message-type constants (Go + TS) from docs/protocol-schema.json
make protocol-verify Fail if the committed protocol constants are stale (used by CI)
make otel-up Start Jaeger (traces) + Prometheus (metrics) via Docker for local OTel development
make otel-down Stop and remove the OTel dev containers

Client (Tauri v2)

Build & dev

Command Description
npm run dev Start Vite dev server with hot reload
npm run build TypeScript check + Vite production build
npm run tauri dev Launch Tauri app in dev mode
npm run tauri build Build release installer (NSIS on Windows, AppImage+deb on Linux)

Tests

Command Description
npm test Run all tests (vitest)
npm run test:unit Unit tests only
npm run test:integration Integration tests only
npm run test:e2e Playwright E2E (mocked Tauri)
npm run test:e2e:native Playwright E2E (real Tauri exe + CDP)
npm run test:e2e:prod Playwright E2E (prod build)
npm run test:e2e:ui Playwright UI mode
npm run test:watch Vitest watch mode
npm run test:coverage Coverage report
npm run test:mutate Stryker mutation testing
npm run test:mutate:dry Stryker dry-run (no mutations applied)
npm run test:browser Vitest browser-mode tests

Type checking, linting & formatting

Command Description
npm run typecheck Full typecheck (all sources)
npm run typecheck:build Typecheck build config only
npm run lint oxlint + ESLint check (src/)
npm run lint:fix ESLint auto-fix
npm run lint:ox oxlint only (fast correctness checks)
npm run format Prettier format (src/ + tests/)
npm run format:check Prettier check only (no writes)
npm run knip Dead code and unused export detection

Committed hooks in .githooks/ catch the most common CI failures locally. Enable once per clone (from the repo root):

npm run hooks:install    # = git config core.hooksPath .githooks
Hook What it runs
pre-commit gofmt + go vet (when Go files staged), oxlint + prettier + tsc --noEmit (when client TS staged), sqlc-verify / protocol-verify (when their inputs staged)
pre-push Server build in all build-tag variants, client typecheck + type-aware ESLint. Set OWNCORD_PREPUSH_TESTS=1 to also run go test -race ./...

Bypass with --no-verify or OWNCORD_SKIP_HOOKS=1 when needed — CI still enforces everything.

Neither hook needs make, and neither needs Node for the Go checks.

core.hooksPath is exclusive. Once set, Git resolves every hook against .githooks/ and never looks in .git/hooks/ again. .githooks/ holds only pre-commit and pre-push, so hooks:install silently disables any other hook you installed there (post-commit, post-checkout, ...). Nothing warns you. Put it under .githooks/ instead (untracked, so it stays yours), or skip hooks:install and use npm run check before pushing.

Plugin Development

Plugins are WASM modules loaded at runtime when the server is built with -tags wazero. See Server/plugin/examples/hello/README.md for the full plugin ABI and build instructions.

Toolchain requirements for building .wasm plugins with TinyGo:

Tool Version Notes
TinyGo 0.40.1 Supports Go 1.191.25 only
Go SDK 1.25.x Install alongside the system Go via go install golang.org/dl/go1.25.3@latest && go1.25.3 download
wasm-opt Binaryen 129 Required by TinyGo for the wasi target; download from Binaryen GitHub releases

Any WASM toolchain (Rust/wasm32-wasi, AssemblyScript, etc.) that exports the five ABI functions is equally valid — TinyGo is just the example toolchain used by examples/hello/.


Branch and PR model

This section is the single source of truth for the branch model. Everywhere else -- the root README.md, CLAUDE.md, the PR template -- summarises it and links here rather than restating it.

  • dev -- the integration branch. All contributions target dev.
  • main -- releases only. dev is merged to main for a release, and release tags are cut from main.

dev is protected and PR-only: direct pushes are rejected, ten status checks are required, required_approving_review_count is 0, and the rule is enforced on admins. So a PR is self-mergeable once CI is green, but no commit reaches dev without CI having run on it. Settings and rationale live in docs/plans/b0-dev-branch-protection.sh.

Two consequences worth knowing before you open a PR:

  • The Docker and Tauri Full Build jobs are gated on main and report as skipped on a PR into dev. That is expected, not a failure.
  • Squash merge, and a conventional commit subject on the squashed commit.

Branch Naming

  • feature/<name> -- new features
  • fix/<name> -- bug fixes
  • docs/<name> -- documentation changes

Commit Format

Use conventional commits:

feat: add thread support to channels
fix: prevent duplicate WebSocket connections
refactor: extract permission checks into middleware
docs: update quick-start guide
test: add integration tests for invite flow
chore: bump Go dependencies
perf: cache role permissions in memory
ci: add lint step to GitHub Actions

Pull Request Process

See Branch and PR model above for what to branch from and target.

  1. Branch from dev
  2. Open the PR against dev
  3. All ten required checks must pass -- dev is protected, so a red PR cannot merge
  4. Request code review
  5. Squash merge, conventional commit subject

Testing

The client suite enforces 70% coverage thresholds in vitest.config.ts; the Go suite has deliberately no floor (T-2026-07-25-19) — use make cover-all to see the honest cross-package number. Follow a test-driven workflow and never lower a threshold to make a change fit.

Code Style

  • TypeScript: See Client Architecture
  • Go: gofmt + golangci-lint, standard library preferred
  • Rust: cargo fmt + cargo clippy, minimal code (native APIs only)

Dependency Policy

The policy behind what the lockfiles already enforce (decided 2026-08-05, closing audit findings 2026-04-07 #8 / DC-11):

  • Lockfiles are authoritative. package-lock.json, go.sum and Cargo.lock pin every transitive dependency; CI installs only from them (npm ci, module/registry verification — never a bare npm install in CI or hooks). package.json keeps ordinary caret ranges: exact-pinning it would duplicate what the lockfile does while making every security patch a manual edit.
  • Upgrades arrive as reviewed PRs, not ambient drift. Dependabot runs weekly per ecosystem (.github/dependabot.yml) with semver-major updates ignored across the board — majors are adopted deliberately, by a human, reading the changelog. Peer-coupled groups (vitest/@vitest/*, @stryker-mutator/*) update as one PR so exact peer pins cannot wedge.
  • Security gates run on every PR: npm audit --omit=dev --audit-level=high (shipped deps only — dev-tooling advisories are triaged in the workflow comment instead of blocking on unfixable pins), govulncheck for Go, cargo audit for Rust, and knip refuses unused client dependencies outright.
  • Version skew is pinned at the toolchain level too: Client/.nvmrc, every actions/setup-node in CI, and an engines block in all three package.json files say Node 24 — with engine-strict=true in each package's .npmrc, so a wrong major fails the install instead of warning. Server/sqlc.version pins sqlc, Go pins via go.mod (GOTOOLCHAIN=auto), and GitHub Actions are SHA-pinned with Dependabot bumping the pins.
