PCE Sync - V2 Team Knowledge Synchronization

Synchronize durable pce-memory knowledge across team members. v2 sync preserves memory_type and follows layer-aware export/import rules.

Argument Parsing

Parse $ARGUMENTS:

• push → Export local knowledge
• pull → Import team knowledge
• status → Check sync state
• No arguments → Run status and guide

Operations

Push (Export)

Export syncable durable knowledge to .pce-shared/.

pce_memory_sync_push()

• Export target: $PCE_SYNC_TARGET_DIR (default: .pce-shared/)
• If PCE_SYNC_AUTO_STAGE=true, auto git add
• Scope filter: Restrict with PCE_SYNC_SCOPE_FILTER
• memory_type is exported with each durable claim
• Session/micro content is excluded
• Rolled-back or tombstoned durable claims are excluded
• promotion_queue is local review state and is never exported

Pull (Import)

Import team knowledge from .pce-shared/.

pce_memory_sync_pull()
// Or dry-run to preview
pce_memory_sync_pull({ dry_run: true })

• CRDT (G-Set) based merge: additions only, no deletions
• Boundary promotion: public < internal < pii < secret (upgrade only)
• memory_type is preserved on import and backfilled onto existing claims only when the receiver is missing it
• Session/micro artifacts remain local-only and are not reconstructed from sync
• promotion_queue stays local-only because it represents review/rollback governance state
• Conflicts: boundary upgrades auto-resolve, entity/relation diffs are still skipped for manual review

Status

pce_memory_sync_status()

Returns:

• Local and remote claim counts
• Unsynced claim count
• Last sync timestamp
• Conflict presence

Git Hooks Integration

Setup

# Install hooks
./scripts/git-hooks/install-hooks.sh

# Set environment
export PCE_SYNC_ENABLED=true

Flow

git commit → pre-commit hook → sync push (auto export)
git pull   → post-merge hook → sync pull (auto import)

Layer-Aware Rules

• micro / session: never sync by default
• meso / project: default sync surface
• macro / principle: sync only after reviewed durable promotion
• promotion_queue: local-only review queue, excluded from Git sync

CRDT Merge Strategy

See crdt-merge-guide.md.

Troubleshooting

• sync push fails: Check state with pce_memory_state. Durable claims must exist before export
• missing session notes after pull: Expected. Session/micro observations do not sync
• rolled-back claim missing from export: Expected. Rolled-back durable memory is excluded
• memory_type differs across peers: Pull backfills missing memory_type, but does not overwrite an existing receiver value unless other merge rules apply
• many unsynced: Check with sync status, then sync push -> git commit -> git push
