# Contributing to `@waggle/hive-mind-core`
This package is the substrate of the Waggle OS memory layer + the Apache 2.0 OSS subtree-split target. Contributions are welcome from anyone — the substrate is built to be a standalone OSS library, not a Waggle-only artifact.
This package is the canonical private-monorepo source for Waggle OS's memory
substrate and its maintainer-curated Apache-2.0 OSS distribution. Contributions
are welcome, but the private tree also contains Waggle-only material and must
never be published directly.
## How the package is distributed
## Distribution and trust boundary
`@waggle/hive-mind-core` lives in the `marolinik/waggle-os` monorepo at `packages/hive-mind-core/`. From there, `git subtree split` periodically emits the contents to a public OSS repo at `github.com/marolinik/hive-mind`.
- Canonical source: private `marolinik/waggle-os`, under
`packages/hive-mind-core/`.
- Public contribution surface: `github.com/marolinik/hive-mind`.
- Distribution mechanism: a reviewed, maintainer-curated forward-port that
adapts layout/imports and removes every private exclusion.
- `scripts/oss-subtree-split.sh` produces local inspection refs only. Raw refs
are never publication sources.
If you're reading this on **github.com/marolinik/hive-mind** (the OSS mirror): file issues + PRs against THAT repo. The maintainer (Egzakta Group) periodically merges accepted upstream changes back into `marolinik/waggle-os` via the inverse subtree-pull.
The public export excludes:
If you're reading this on **github.com/marolinik/waggle-os** (the canonical monorepo): file issues + PRs directly here. Changes ship to OSS via the next `subtree split` cycle.
- `src/mind/evolution-runs.ts`
- `src/mind/execution-traces.ts`
- `src/mind/improvement-signals.ts`
- private vault/compliance surfaces outside this package
- interleaved `install_audit` DDL and migration logic inside
`src/mind/{schema,db}.ts`
The OSS-export filter excludes Waggle-proprietary files documented in `EXTRACTION.md` (when present) — currently `vault.ts`, `evolution-runs.ts`, `execution-traces.ts`, `improvement-signals.ts`, and `compliance/**` stay in `@waggle/core`, not `@waggle/hive-mind-core`. PRs touching those files belong on the waggle-os monorepo only.
A file filter cannot enforce the interleaved exclusion.
## Direction of development (maintainers — ratified 2026-06-11)
## Direction of development
**The monorepo is the sole source of truth. Maintainers must not author features directly on the OSS mirror.** This invariant broke once: the cross-encoder reranker was written directly on `marolinik/hive-mind` during a benchmark arc and existed only there until a recon pass found it and reverse-ported it (waggle-os `f47ee8f`). The rules that prevent a repeat:
The private monorepo is the sole source of truth. Maintainers must not author
features only in the public mirror.
1. Substrate changes are authored in `waggle-os/packages/hive-mind-core/` first; the mirror is regenerated via `scripts/oss-subtree-split.sh` afterward.
2. Work done in a scratch `hive-mind` checkout (benchmarks, experiments) must be reverse-ported into the monorepo in the same work arc — never left to accumulate on the mirror.
3. Run `scripts/oss-drift-check.sh` before every OSS release push and after any arc that touched a hive-mind checkout. It file-diffs the mapped source trees and flags ONLY-IN-OSS files (the reverse-port failure mode), ONLY-IN-MONO files (pending export), and divergent edits.
4. External contributor PRs against the OSS repo are welcome (see above) — the maintainer merges accepted changes back into the monorepo via subtree-pull, then re-splits.
1. Author substrate changes in `waggle-os/packages/hive-mind-core/` first.
2. Reverse-port accepted public contributions into the private monorepo before
the next curated export.
3. Run `scripts/oss-drift-check.sh` before every OSS release and after any arc
that touched a Hive Mind checkout. The thin shell entrypoint delegates to
the cross-platform Node 20 checker, which validates
`scripts/oss-drift-baseline.json` without updating or accepting it. Separate
sections identify reviewed adaptations, intentional private exclusions,
known reviewed blockers, unreviewed differences, forbidden whole-file
leaks, and any interleaved `install_audit` marker, including comments.
4. Treat exit `1` as release-blocking source drift and exit `2` as an
untrustworthy setup/configuration result. Exit `0` means the mapped bytes
exactly match the reviewed clean baseline; it is not a substitute for
maintainer review of a new forward-port.
## Setting up the dev environment
## Development setup
### External contributors
Use the public mirror; private Waggle OS access is neither required nor
expected.
```bash
# Clone the monorepo
git clone https://github.com/marolinik/waggle-os.git
cd waggle-os
# Install workspace deps (registers all packages including hive-mind-core)
git clone https://github.com/marolinik/hive-mind.git
cd hive-mind
npm install
# Build the substrate
cd packages/hive-mind-core
npx tsc --build
# Run hive-mind-core's tests in isolation
npx vitest run
# Run the full repo test suite
cd ../..
npm run build
npm run test
npm run lint
```
Node.js >= 20 required. macOS and Linux work natively. Windows works with the postinstall override that `@waggle/hive-mind-cli` provides — see `packages/hive-mind-cli/docs/WINDOWS-QUIRKS.md`.
Open branches, issues, and pull requests against `marolinik/hive-mind`.
### Maintainers with private access
```bash
git clone https://github.com/marolinik/waggle-os.git
cd waggle-os
npm install
npx tsc --build packages/hive-mind-core/tsconfig.json
npx vitest run packages/hive-mind-core/tests
```
After the canonical change lands, prepare a separate curated forward-port in a
clean public-mirror branch and review the complete export diff.
Node.js 20 or newer is required. Public contributors should use the public
mirror README and issues for current platform support. Maintainers working in
the private monorepo can additionally consult
`packages/hive-mind-cli/docs/WINDOWS-QUIRKS.md`.
## Code style
- TypeScript strict mode (the monorepo `tsconfig.base.json` enables `strict: true`, `noImplicitAny`, `noUnusedLocals`, `noUnusedParameters`)
- ESM modules — `.js` extensions on all relative imports for runtime resolution after tsc emit
- No `any` in application code — use `unknown` + narrowing
- Public API methods + exported functions get explicit return types
- Internal class methods can rely on type inference
- TypeScript strict mode; avoid `any` in application code.
- ESM modules with `.js` extensions on relative imports where required by the
emitted runtime.
- Explicit return types for exported functions and public API methods.
- Follow the repository-root ESLint configuration.
The repository uses ESLint at the workspace root — run `npm run lint` from the repo root.
## Pull request checklist
## Pull request guidelines
1. Work in the repository you are authorized to access: external contributors
use `marolinik/hive-mind`; maintainers use the private canonical monorepo.
2. Name branches `feat/<short-description>` or `fix/<short-description>`.
3. Add or extend tests for every non-trivial change.
4. Run that repository's build, tests, and lint before opening the PR.
5. In the PR body, explain the change, list verification, and state whether the
curated OSS surface is affected.
1. **Fork** the canonical waggle-os repo (or work on a branch in your local clone if you have direct push access).
2. **Create a branch** named `feat/<short-description>` or `fix/<short-description>`.
3. **Test first** — for any non-trivial change, add or extend a test in `packages/hive-mind-core/tests/`. Existing tests are organized by substrate area (`tests/mind/`, `tests/harvest/`).
4. **Run the full suite** — `npm run test` from the repo root. Failing tests block the PR. (Some env-dependent tests are expected to fail without local Postgres + Redis — they're marked in the `marketplace` + `server` packages, not in `hive-mind-core`.)
5. **tsc must compile clean** — `npx tsc --build` from the package root.
6. **Open the PR** against `main` of waggle-os. Include in the PR body:
- What changed + why
- Test plan (which test files added/modified)
- Whether the change affects the OSS subtree-split surface (i.e., introduces new public exports, changes existing public types, deprecates surface)
Maintainers reverse-port accepted public changes into the canonical monorepo
before preparing the next curated export.
Maintainer review aim: 2 business days for triage, additional time for substantial changes.

## Status
Migrated from `marolinik/hive-mind` repo into `marolinik/waggle-os` monorepo at `packages/hive-mind-core/` per CC Sesija B brief 2026-04-30. Future development happens in this monorepo; `git subtree split` periodically emits `packages/hive-mind-core/` to `marolinik/hive-mind` for OSS distribution.
Migrated from `marolinik/hive-mind` into the canonical `marolinik/waggle-os` monorepo at `packages/hive-mind-core/` on 2026-04-30. Future development happens here. `scripts/oss-subtree-split.sh` is an inspection/curation starting point only; the public mirror is updated through a reviewed, curated forward-port.
