## §2 — Workflow file inventory
### `.github/workflows/mind-parity-check.yml` (NEW)
**Trigger:** PR + push to main, paths-filtered to
`packages/core/src/mind/**`, `packages/core/src/harvest/**`,
`packages/core/tests/mind/**`.
**Steps:**
1. Checkout waggle-os + hive-mind master (separate paths)
2. Setup Node 20 (matches existing waggle-os ci.yml convention)
3. Cache npm
4. Install waggle-os dependencies
5. Run **baseline** waggle-os mind/ tests (regression catch-net)
6. **Inject** latest hive-mind tests under `-hive-mind.test.ts`:
- Skip if listed in `.parity-allowlist`
- **Keep if already committed** (Step 2 port preserves bespoke header
comments + waggle-os-side adaptations)
- Otherwise copy with sed-adapted import paths
7. Run **combined** suite (waggle-os baseline + injected)
8. Emit informational diff of shared substrate file sizes (not a gate)
**Failure semantics:**
- Baseline failure → regular regression, blocks merge
- Combined-suite failure on a `-hive-mind.test.ts` → either:
- waggle-os has a real bug (fix + re-push), OR
- hive-mind tests an intentionally divergent behavior — add to
`.parity-allowlist` with documented reason
### `.github/workflows/sync-mind.yml` (NEW)
**Trigger:** push to main, paths-filtered to
`packages/core/src/mind/**`, `packages/core/src/harvest/**`.
**Steps:**
1. Checkout waggle-os with full history
2. Verify `HIVE_MIND_SYNC_TOKEN` secret present (fail fast if absent)
3. Compute filtered diff:
- Range = `${{ github.event.before }}` → `${{ github.sha }}`
- Fall back to `HEAD~1` for first-push edge case
- Apply EXTRACTION.md "NOT extracted" filter:
```
packages/core/src/mind/vault.ts
packages/core/src/mind/evolution-runs.ts
packages/core/src/mind/execution-traces.ts
packages/core/src/mind/improvement-signals.ts
packages/core/src/compliance/**
```
- Skip workflow entirely if filter empties the diff
4. Checkout marolinik/hive-mind master (using HIVE_MIND_SYNC_TOKEN)
5. Apply patch via `git apply --3way` on a new branch
`auto-sync/waggle-os-`
6. Push branch + open PR via `gh pr create` with structured body
including originating commits, source SHA, NOT-extracted filter list,
and review checklist
7. Upload patch artifact as debug aid (30-day retention)
**Kill switches:**
- `MIND_SYNC_ENABLED` repo variable (set to `'true'` to enable; otherwise
workflow's `if:` skips the entire job)
- Token absent → fail fast with structured error message pointing at
`.github/sync.md` setup section
### `.parity-allowlist` (NEW)
Single-entry initial state:
```
db-hive-mind.test.ts
```
Reason documented inline in the file: hive-mind's `db.test.ts` asserts
proprietary tables MUST BE ABSENT (its OSS-scrub guarantee); waggle-os
legitimately carries them per EXTRACTION.md. The waggle-os adaptation
lives in committed `db.test.ts` (no suffix) which splits the assertion
into "OSS shared must exist" (verbatim) + "Waggle-specific must exist"
(inverted). Cross-references EXTRACTION.md and Step 2 results memo.
### `.github/sync.md` (NEW, ~165 lines)
Operating manual covering:
- TL;DR table mapping common dev actions to workflow outcomes
- Why the sync system exists (audit context)
- Per-workflow design + failure modes + recovery procedures
- `.parity-allowlist` add/remove policy
- Direction note: this PR ships ONLY waggle-os → hive-mind direction;
the empirically PRIMARY direction (hive-mind → waggle-os) requires a
workflow living in the hive-mind repo and is intentionally deferred
to a sibling PR after Step 3 ratification (out of CC-2 scope)
- `HIVE_MIND_SYNC_TOKEN` setup instructions for Marko
- Bidirectional bug-fix protocol (3 steps for waggle-os-originated, 3
steps for hive-mind-originated)
### `CLAUDE.md` Section 7.5 (NEW, between Security and Already-Built sections)
Concise pointer for any future contributor working on
`packages/core/src/mind/` or `packages/core/src/harvest/`. Highlights:
- Sync workflows exist; consult `.github/sync.md` first
- Adding a new "stays in waggle-os" file requires updating BOTH
`sync-mind.yml`'s `excluded_paths` AND hive-mind's EXTRACTION.md in
the same PR
### `scripts/parity-check.sh` (NEW)
Local-dev wrapper that mirrors the CI `mind-parity-check` job's logic.
Lets a developer run the same parity check before pushing.
Usage:
```bash
scripts/parity-check.sh # run + clean up
scripts/parity-check.sh --keep-injected # leave injected files for inspection
```
Locates hive-mind via `HIVE_MIND_PATH` env var, falls back to
`D:/Projects/hive-mind` (Windows default) or `~/Projects/hive-mind`
(Unix default).

## §3 — Verification done in CC-2 session
1. **YAML syntax validation** — both workflow files parse cleanly via
`python yaml.safe_load`. No structural issues.
2. **Parity-check inject-logic dry-run** (sandbox first, then real
`tests/mind/` folder with cleanup tracking):
- Allowlist correctly skips `db-hive-mind.test.ts`
- 14 injection candidates from hive-mind master
- 8 already-committed (Step 2 ports) → kept untouched
- 6 NEW under suffix names → injected with sed-adapted imports
- Combined suite: 34 files / **410 tests PASS**
- Cleanup removes the 6 injected files; baseline restored
3. **Skip-if-committed safety** — first dry-run iteration of the script
incorrectly OVERWROTE the 8 Step 2 committed `-hive-mind` files,
silently dropping the bespoke header comments documenting port
provenance + adaptation rationale. Caught by reviewing
`git status --short`. Restored via `git checkout HEAD --` and
updated BOTH the local script AND the workflow YAML to skip-if-file-
exists. Updated `.github/sync.md` to document this rule explicitly.
Re-ran dry-run: zero modifications to committed files, 410/410 pass.
4. **Filter-list correctness** — manually traced
`excluded_paths` array in `sync-mind.yml` against EXTRACTION.md
"NOT Extracted" section. All 5 paths present:
- `packages/core/src/mind/vault.ts` ✓
- `packages/core/src/mind/evolution-runs.ts` ✓
- `packages/core/src/mind/execution-traces.ts` ✓
- `packages/core/src/mind/improvement-signals.ts` ✓
- `packages/core/src/compliance` (and subpaths) ✓

## §4 — Verification deferred to Marko's environment
These steps need Marko's GitHub admin access + a real test branch push.
None blocking on Step 3 brief authoring or memo close-out.
1. **`HIVE_MIND_SYNC_TOKEN` secret creation:**
```bash
gh secret set HIVE_MIND_SYNC_TOKEN --repo marolinik/waggle-os
gh variable set MIND_SYNC_ENABLED --body 'true' --repo marolinik/waggle-os
```
Until done, `sync-mind.yml` job evaluates its `if:` to false and
skips entirely. `mind-parity-check.yml` doesn't need the token at
all — it works immediately on PR.
2. **Synthetic test branch end-to-end:**
- Create branch `test/parity-check-smoke` off main
- Touch `packages/core/src/mind/frames.ts` trivially (whitespace)
- Push and open PR → `mind-parity-check.yml` should run + pass
- After PR merge to main → `sync-mind.yml` should fire and open a
real PR on `marolinik/hive-mind` (assumes secret + variable set)
- Close the auto-PR on hive-mind side without merging (it's a smoke
test — production adopt would happen on real next mind/ change)
3. **Hive-mind side workflow** (the empirically primary direction —
hive-mind → waggle-os auto-PR): per Step 1 §3 + Step 2 §5 finding,
hive-mind is the more active substrate repo, so the
hive-mind-originated direction carries the heavier production
burden. Sibling PR to hive-mind after Step 3 ratification will add
the symmetric workflow there. Out of CC-2 scope per brief.

## §5 — Halt-and-ping triggers — none fired
| Trigger | Status |
|---------|--------|
| (1) Workflow YAML / GitHub Actions concept reveals constraint | ✅ NOT FIRED — both files validate; paths-filter at `on:` level + `if:` conditions handle all cases |
| (2) Parity-check reveals false-positive failures | ✅ NOT FIRED — overwrite bug caught + fixed before any committed file lost |
| (3) `HIVE_MIND_SYNC_TOKEN` secret unavailable | ⚠ Anticipated, not blocking. Workflow fails fast with clear error pointing to setup instructions in `.github/sync.md`. Not a halt — just a deferred operator action. |
| (4) Cumulative time > 5h on Step 3 | ✅ NOT FIRED — Step 3 completed in ~2h 30m CC-2 work |
---
## §6 — Files added/modified
```
.github/workflows/mind-parity-check.yml NEW
.github/workflows/sync-mind.yml NEW
.github/sync.md NEW
.parity-allowlist NEW
scripts/parity-check.sh NEW (executable)
CLAUDE.md MODIFIED (added Section 7.5)
```
No source code under `packages/core/src/` modified. No test files
modified (the temporary corruption from dry-run was reverted before
commit).
---
## §7 — Rollback procedure (if Step 3 needs to be unwound)
```bash
# Disable both workflows without deletion (preserves history).
gh variable set MIND_SYNC_ENABLED --body 'false' --repo marolinik/waggle-os
# Comment out trigger paths in mind-parity-check.yml or delete file
git rm .github/workflows/sync-mind.yml
git rm .github/workflows/mind-parity-check.yml
# Or hard rollback (after PM approval):
git revert
# Step 1 + Step 2 commits are independent — sync workflow rollback
# does NOT undo the substrate fixes (timestamp persist + preview cap
# raise) or the test ports. Those remain in main on their own merits.
```

## §8 — Aggregate Memory Sync Repair status
| Step | Status | Files | Tests | Memo |
|------|--------|-------|-------|------|
| 1 — Forward port + bidirectional audit | ✅ closed | 4 | 480/480 + 30/30 frames + 23/23 server harvest + 8/8 GEPA | step1 results |
| 2 — Test port (15 hive-mind tests) | ✅ closed | 14 | 111/111 + 480/480 regression | step2 results |
| 3 — CI/CD sync workflow | ⏸ awaiting PM ratification | 6 | parity-check 410/410 dry-run | this memo |
| **Total** | | **24** | | |
Substrate parity is **empirically + structurally + procedurally**
verified across the three steps:
- **Empirically (Step 1+2)**: zero bugs, zero API drift, all 591 mind/
tests pass against waggle-os substrate
- **Structurally (Step 3.1)**: parity-check workflow blocks merge if
drift appears in the future
- **Procedurally (Step 3.2)**: sync workflow auto-opens hive-mind PR
on every relevant waggle-os main push, propagating fixes
automatically through human-reviewed PRs
---
## §9 — Open questions for PM
1. **Confirm Step 3 CLOSED:** ratify all 6 deliverables + accept the 2
deferred-to-Marko verification items as non-blocking?
2. **`MIND_SYNC_ENABLED` initial value:** start as `false` (workflows
shipped but inactive until manually flipped) or `true` (active
immediately on Marko setting the secret)?
3. **Hive-mind side workflow:** authorize CC-2 to author the sibling
PR for the hive-mind → waggle-os auto-sync direction in the
hive-mind repo, or punt to a separate session/task?
4. **Memory Sync Repair closure ceremony:** all 3 steps closed, do you
want a final consolidated memo `2026-04-27-memory-sync-repair-CLOSED.md`
that pulls together the 3 step memos + lessons learned + runbook
for ongoing maintenance, or keep the per-step memos as the
audit trail?
---
## §10 — Status: AWAITING PM RATIFICATION
Step 3 complete. 6 deliverables shipped, dry-runs green, no halt-triggers
fired. CC-2 session standing GREEN, halted before final sign-off.
**PM action required:** confirm Step 3 CLOSED → optional follow-ups per
§9 questions.
