Verbatim Provenance Archive (#7) Implementation Plan
For agentic workers: REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (
- [ ]) syntax for tracking.
Goal: Add an append-only, immutable raw_archive that stores the full untruncated verbatim source of each harvest item, linked from the frames it produced via frame.metadata.archiveUid, with a reconstructSource(frameId) audit query.
Architecture: New substrate table raw_archive (in @waggle/hive-mind-core) with ai_interactions-style append-only DDL triggers; a RawArchive store class; one wiring point in the server harvest route's per-item loop. No change to search.ts/scoring.ts or the memory_frames schema — the link rides the existing metadata JSON column. Spec: docs/plans/2026-06-30-verbatim-provenance-archive-design.md.
Tech Stack: TypeScript, better-sqlite3, node:crypto, Vitest. Monorepo packages hive-mind-core, core, server.
Global Constraints
- No retrieval-path edits. Do not touch
mind/search.ts,mind/scoring.ts, ormemory_framescolumns. 87.66% LoCoMo SOTA must remain regression-locked. - Substrate lands in
packages/hive-mind-core/first (CLAUDE.md §7.5).raw_archiveis OSS-bound (generic provenance, likeai_interactions) — do NOT edit the OSS mirror; flag for the next regeneration. - Append-only is enforced at the DB layer via
BEFORE UPDATE/DELETEtriggers. Inserts MUST useINSERT OR IGNORE(neverOR REPLACE— that DELETEs + INSERTs and trips the no-delete trigger). - Zero-loss forensic semantics: archive content is stored verbatim even when injection-flagged (the row is never fed to an LLM). raw-turns drops; the archive flags-but-keeps.
- No new dependencies. Use
node:cryptocreateHash(already used bycontent-hash.ts). - Conventional-commit messages, scoped, no attribution trailers (repo convention).
- Verify after touching
packages/server:npx tsc --noEmit --project packages/server/tsconfig.json(the sidecar runs via tsx and is NOT typechecked by the web build — CLAUDE.md §2).

Task 1: raw_archive schema + migration
Files:
- Modify:
packages/hive-mind-core/src/mind/schema.ts(append toSCHEMA_SQL, before the closing`) - Modify:
packages/hive-mind-core/src/mind/db.ts(insiderunMigrations(), after theai_interactionstriggers block ~line 299) - Test:
packages/hive-mind-core/tests/mind/raw-archive.test.ts
Interfaces:
-
Produces: a
raw_archivetable with columns(id, archive_uid UNIQUE, source, source_ref, title, content, content_sha256, injection_flagged, injection_flags, source_timestamp, created_at), indexesidx_raw_archive_source_ref/idx_raw_archive_created, and triggersraw_archive_no_update/raw_archive_no_delete. Created on both fresh DBs (SCHEMA_SQL) and existing DBs (runMigrations). -
Step 1: Write the failing test
Create packages/hive-mind-core/tests/mind/raw-archive.test.ts:
import { describe, it, expect, beforeEach, afterEach } from 'vitest';
import { MindDB } from '../../src/mind/db.js';
describe('raw_archive schema', () => {
let db: MindDB;
beforeEach(() => { db = new MindDB(':memory:'); });
afterEach(() => { db.close(); });
it('creates the raw_archive table with the expected columns', () => {
const raw = db.getDatabase();
const cols = (raw.prepare("PRAGMA table_info('raw_archive')").all() as { name: string }[])
.map(c => c.name);
expect(cols).toEqual(expect.arrayContaining([
'id', 'archive_uid', 'source', 'source_ref', 'title', 'content',
'content_sha256', 'injection_flagged', 'injection_flags', 'source_timestamp', 'created_at',
]));
});
it('rejects UPDATE and DELETE (append-only triggers)', () => {
const raw = db.getDatabase();
raw.prepare(
`INSERT INTO raw_archive (archive_uid, source, content, content_sha256)
VALUES ('uid1', 'claude', 'hello', 'uid1')`
).run();
expect(() => raw.prepare("UPDATE raw_archive SET content = 'x' WHERE archive_uid = 'uid1'").run())
.toThrow(/append-only/);
expect(() => raw.prepare("DELETE FROM raw_archive WHERE archive_uid = 'uid1'").run())
.toThrow(/append-only/);
});
});
- Step 2: Run test to verify it fails
Run: npx vitest run packages/hive-mind-core/tests/mind/raw-archive.test.ts
Expected: FAIL — no such table: raw_archive.
- Step 3: Add the DDL to
SCHEMA_SQL
In packages/hive-mind-core/src/mind/schema.ts, insert this block immediately before the closing ` that ends SCHEMA_SQL (after the memory_frame_chunks block, ~line 303):
-- Verbatim Provenance Archive (#7, 2026-06-30): append-only, immutable, full-fidelity
-- copy of each harvested source item. Distilled/imported frames link back via
-- memory_frames.metadata.archiveUid. NOT part of the retrieval corpus (no FTS/vec) —
-- audit/reconstruction only. Append-only triggers mirror ai_interactions (Layer 7).
CREATE TABLE IF NOT EXISTS raw_archive (
id INTEGER PRIMARY KEY AUTOINCREMENT,
archive_uid TEXT NOT NULL UNIQUE,
source TEXT NOT NULL,
source_ref TEXT,
title TEXT,
content TEXT NOT NULL,
content_sha256 TEXT NOT NULL,
injection_flagged INTEGER NOT NULL DEFAULT 0,
injection_flags TEXT NOT NULL DEFAULT '',
source_timestamp TEXT,
created_at TEXT NOT NULL DEFAULT (datetime('now'))
);
CREATE INDEX IF NOT EXISTS idx_raw_archive_source_ref ON raw_archive (source, source_ref);
CREATE INDEX IF NOT EXISTS idx_raw_archive_created ON raw_archive (created_at DESC);
CREATE TRIGGER IF NOT EXISTS raw_archive_no_update
BEFORE UPDATE ON raw_archive
BEGIN SELECT RAISE(ABORT, 'raw_archive is append-only (verbatim provenance archive)'); END;
CREATE TRIGGER IF NOT EXISTS raw_archive_no_delete
BEFORE DELETE ON raw_archive
BEGIN SELECT RAISE(ABORT, 'raw_archive is append-only (verbatim provenance archive)'); END;
- Step 4: Add the idempotent migration for existing DBs
In packages/hive-mind-core/src/mind/db.ts, inside runMigrations(), immediately after the ai_interactions append-only trigger this.db.exec(...) calls (~line 299) and before this.backfillKgEntityFrames();:
// #7 (2026-06-30): verbatim provenance archive — append-only, immutable.
// Idempotent; SCHEMA_SQL carries the same DDL for fresh DBs. Not in the
// retrieval corpus (no FTS/vec). Append-only triggers mirror ai_interactions.
this.db.exec(`
CREATE TABLE IF NOT EXISTS raw_archive (
id INTEGER PRIMARY KEY AUTOINCREMENT,
archive_uid TEXT NOT NULL UNIQUE,
source TEXT NOT NULL,
source_ref TEXT,
title TEXT,
content TEXT NOT NULL,
content_sha256 TEXT NOT NULL,
injection_flagged INTEGER NOT NULL DEFAULT 0,
injection_flags TEXT NOT NULL DEFAULT '',
source_timestamp TEXT,
created_at TEXT NOT NULL DEFAULT (datetime('now'))
);
CREATE INDEX IF NOT EXISTS idx_raw_archive_source_ref ON raw_archive (source, source_ref);
CREATE INDEX IF NOT EXISTS idx_raw_archive_created ON raw_archive (created_at DESC);
`);
this.db.exec(
"CREATE TRIGGER IF NOT EXISTS raw_archive_no_update BEFORE UPDATE ON raw_archive BEGIN SELECT RAISE(ABORT, 'raw_archive is append-only (verbatim provenance archive)'); END"
);
this.db.exec(
"CREATE TRIGGER IF NOT EXISTS raw_archive_no_delete BEFORE DELETE ON raw_archive BEGIN SELECT RAISE(ABORT, 'raw_archive is append-only (verbatim provenance archive)'); END"
);
- Step 5: Run test to verify it passes
Run: npx vitest run packages/hive-mind-core/tests/mind/raw-archive.test.ts
Expected: PASS (2 tests).
- Step 6: Commit
git add packages/hive-mind-core/src/mind/schema.ts packages/hive-mind-core/src/mind/db.ts packages/hive-mind-core/tests/mind/raw-archive.test.ts
git commit -m "feat(hive-mind-core): raw_archive append-only schema + migration (#7)"
Task 2: RawArchive store
Files:
- Create:
packages/hive-mind-core/src/mind/raw-archive.ts - Modify:
packages/hive-mind-core/src/index.ts(add export near the FrameStore export, ~line 20) - Test:
packages/hive-mind-core/tests/mind/raw-archive.test.ts(extend)
Interfaces:
-
Consumes:
MindDB(from./db.js),scanForInjection(from../injection-scanner.js),FrameStore(test-only, for the round-trip). -
Produces:
class RawArchive { constructor(db: MindDB); append(input: ArchiveInput): { archiveUid: string; created: boolean }; getByUid(archiveUid: string): RawArchiveRow | undefined; reconstructSource(frameId: number): RawArchiveRow | undefined; list(opts?: { limit?: number; offset?: number; source?: string }): RawArchiveRow[]; count(): number }interface ArchiveInput { source: string; sourceRef?: string; title?: string; content: string; sourceTimestamp?: string }interface RawArchiveRow { id: number; archive_uid: string; source: string; source_ref: string | null; title: string | null; content: string; content_sha256: string; injection_flagged: 0 | 1; injection_flags: string; source_timestamp: string | null; created_at: string }function hashRaw(content: string): string(sha256 hex over the raw content)
-
Step 1: Write the failing tests
Append to packages/hive-mind-core/tests/mind/raw-archive.test.ts:
import { RawArchive } from '../../src/mind/raw-archive.js';
import { FrameStore } from '../../src/mind/frames.js';
import { SessionStore } from '../../src/mind/sessions.js';
describe('RawArchive store', () => {
let db: MindDB;
let archive: RawArchive;
beforeEach(() => { db = new MindDB(':memory:'); archive = new RawArchive(db); });
afterEach(() => { db.close(); });
it('append inserts a row and returns created:true with a stable sha256 uid', () => {
const r = archive.append({ source: 'claude', sourceRef: 'item-1', content: 'hello world' });

expect(row?.content_sha256).toBe(r.archiveUid);
});
it('append is idempotent on identical content (one row, created:false on repeat)', () => {
const a = archive.append({ source: 'claude', content: 'same body' });
const b = archive.append({ source: 'gemini', content: 'same body' });
expect(a.archiveUid).toBe(b.archiveUid);

expect(archive.getByUid(r.archiveUid)!.content.length).toBe(25_000);
});
it('reconstructSource round-trips frame.metadata.archiveUid → row; undefined when unlinked', () => {
const sessions = new SessionStore(db);
sessions.ensure?.('harvest', 'harvest', 'test') ?? sessions.create();
const frames = new FrameStore(db);
const r = archive.append({ source: 'claude', sourceRef: 'c1', content: 'the source text' });
const f = frames.createIFrame('harvest', 'distilled summary', 'normal', 'import');
frames.setMetadata(f.id, JSON.stringify({ sourceId: 'c1', archiveUid: r.archiveUid }));

archive.append({ source: 'claude', content: 'c' });
expect(archive.list({ source: 'claude' }).length).toBe(2);
expect(archive.list({ limit: 1 }).length).toBe(1);
});
});
Note: the round-trip test uses the
harvestsession (frames FK tosessions(gop_id)).SessionStore.ensure('harvest', …)is the harvest-route pattern; ifensureis unavailable in the test build, fall back tosessions.create()and pass the returnedgop_idtocreateIFrame.
- Step 2: Run tests to verify they fail
Run: npx vitest run packages/hive-mind-core/tests/mind/raw-archive.test.ts
Expected: FAIL — Cannot find module '../../src/mind/raw-archive.js'.
- Step 3: Implement
raw-archive.ts
Create packages/hive-mind-core/src/mind/raw-archive.ts:
/**
* raw-archive.ts — #7 Verbatim Provenance Archive (2026-06-30).
*
* Append-only, immutable store of the FULL verbatim source of each harvested
* item. Distilled/imported frames link back via memory_frames.metadata.archiveUid;
* reconstructSource(frameId) resolves that link for audit / EU-AI-Act reconstruction.
*
* NOT part of the retrieval corpus (no FTS/vec, never fed to an LLM) — so unlike
* raw-turns (which DROPS injection payloads because they feed recall), this store
* keeps flagged content verbatim and records the flag. Idempotent on content sha256.
* Append-only is enforced by DDL triggers; inserts use INSERT OR IGNORE (OR REPLACE
* would DELETE+INSERT and trip the no-delete trigger).

Task 3: @waggle/core re-export + server harvest wiring
Files:
- Modify:
packages/core/src/index.ts(substrate re-export block, ~lines 16–106) - Modify:
packages/server/src/local/routes/harvest.ts(import ~line 21; instantiate afterframeStore~line 412; per-item loop ~lines 455–474) - Test:
packages/server/tests/local/harvest-provenance.test.ts
Interfaces:
-
Consumes:
RawArchive(from@waggle/coreafter the re-export),FrameStore,personalDb(the route'sMindDB). -
Produces: every harvested frame on the server route carries
metadata.archiveUidresolving to its immutableraw_archiverow. -
Step 1: Write the failing integration test
Create packages/server/tests/local/harvest-provenance.test.ts:
import { describe, it, expect, beforeEach, afterEach } from 'vitest';
import { MindDB, FrameStore, SessionStore, RawArchive } from '@waggle/core';
// Mirrors the harvest route's per-item persistence: archive the full verbatim,
// create the (truncated) summary frame, stamp metadata.archiveUid alongside sourceId.
function persistHarvestItem(
db: MindDB,
item: { source: string; id: string; title: string; content: string },
) {
const archive = new RawArchive(db);
const frames = new FrameStore(db);
const { archiveUid } = archive.append({
source: item.source, sourceRef: item.id, title: item.title, content: item.content,
});
const frame = frames.createIFrame('harvest', `${item.title}\n\n${item.content.slice(0, 10_000)}`, 'normal', 'import');
frames.setMetadata(frame.id, JSON.stringify({ status: 'unreviewed', sourceId: item.id, archiveUid }));
return { archive, frame };
}
describe('harvest provenance archive', () => {
let db: MindDB;
beforeEach(() => {
db = new MindDB(':memory:');
new SessionStore(db).ensure('harvest', 'harvest', 'test');
});
afterEach(() => { db.close(); });
it('a harvested frame links to its full immutable raw_archive row', () => {
const big = 'A'.repeat(25_000);
const { archive, frame } = persistHarvestItem(db, { source: 'claude', id: 'c1', title: 'T', content: big });
const src = archive.reconstructSource(frame.id);
expect(src?.content.length).toBe(25_000); // full source survived (frame is capped at 10K)
expect(frame.content.length).toBeLessThanOrEqual(10_000 + 4);
});
it('re-importing the same item does not duplicate the archive row', () => {
const item = { source: 'claude', id: 'c2', title: 'T', content: 'same content' };
const { archive } = persistHarvestItem(db, item);
persistHarvestItem(db, item);
expect(archive.count()).toBe(1);
});
});
- Step 2: Run test to verify it fails
Run: npx vitest run packages/server/tests/local/harvest-provenance.test.ts
Expected: FAIL — RawArchive is not exported from @waggle/core.
- Step 3: Add the
@waggle/corere-export
In packages/core/src/index.ts, inside the export { … } from '@waggle/hive-mind-core'; block, add to the FrameStore line (~line 25) — append on its own line within the block:
RawArchive, hashRaw,
type RawArchiveRow, type ArchiveInput,
(Place alongside the existing FrameStore, stripHmPrefix, hashFrameContent, entry so it stays inside the single re-export block that ends } from '@waggle/hive-mind-core';.)
- Step 4: Run the integration test to confirm the export resolves the failure
Run: npx vitest run packages/server/tests/local/harvest-provenance.test.ts
Expected: PASS (both tests — the test's persistHarvestItem helper already exercises the wiring shape).
- Step 5: Wire the live harvest route
In packages/server/src/local/routes/harvest.ts:
(a) Add RawArchive to the import at line 408:
const { FrameStore, SessionStore, RawArchive } = await import('@waggle/core');
(b) Instantiate after const frameStore = new FrameStore(personalDb); (line 412):
const rawArchive = new RawArchive(personalDb);
(c) In the per-item loop, BEFORE the createIFrame call (~line 455), archive the full verbatim and capture the uid (best-effort — a failure must not abort the item):
let archiveUid: string | undefined;
try {
archiveUid = rawArchive.append({
source: item.source,
sourceRef: item.id,
title: item.title,
content: item.content,
sourceTimestamp: providedTimestamp,
}).archiveUid;
} catch (err) {
request.log.warn(
{ source: item.source, itemId: item.id, err: err instanceof Error ? err.message : 'unknown' },
'[harvest] raw_archive append failed — frame persists without provenance link',
);
}
(d) Add archiveUid to the existing metadata stamp (~lines 467–474), so the object becomes:
if (!frame.metadata || frame.metadata === '{}') {
frameStore.setMetadata(frame.id, JSON.stringify({
kind: importItemTypeToMemoryKind(item.type),
confidence: harvestConfidence(item),
status: 'unreviewed',
sourceId: item.id,
...(archiveUid ? { archiveUid } : {}),
}));
}
- Step 6: Typecheck the server (sidecar is NOT covered by the web build)
Run: npx tsc --noEmit --project packages/server/tsconfig.json
Expected: 0 errors.
- Step 7: Run both new test files + the existing harvest tests
Run: npx vitest run packages/hive-mind-core/tests/mind/raw-archive.test.ts packages/server/tests/local/harvest-provenance.test.ts packages/server/tests/local/harvest-runs.test.ts packages/server/tests/local/import.test.ts
Expected: PASS (no regression in existing harvest tests).
- Step 8: Commit
git add packages/core/src/index.ts packages/server/src/local/routes/harvest.ts packages/server/tests/local/harvest-provenance.test.ts
git commit -m "feat(server): wire raw_archive provenance into harvest route (#7)"
Self-Review
Spec coverage:
- raw_archive table + append-only triggers → Task 1. ✓
- RawArchive store (append idempotent, injection-flag-keep, getByUid, reconstructSource, list/count) → Task 2. ✓
- frame link via metadata.archiveUid, no memory_frames migration → Task 3 (d). ✓
- Wiring at server harvest route only; full content vs 10K frame cap → Task 3. ✓
- Idempotency by content_sha256 / INSERT OR IGNORE → Task 1 (constraint) + Task 2 test. ✓
- Zero search/scoring touch → no task edits them (Global Constraints). ✓
- Error handling: append best-effort, reconstructSource returns undefined → Task 2 + Task 3 (c). ✓
- Tests: all 8 unit + 2 integration → Tasks 1–3. ✓
- OSS-bound note, MCP/pipeline follow-ups → spec §8/§9 (no task; documented non-goals). ✓
Placeholder scan: none — all code blocks are complete; the one fallback note (SessionStore.ensure vs create) is an explicit either/or, not a TBD.
Type consistency: append returns { archiveUid, created } everywhere; ArchiveInput/RawArchiveRow fields match the SQL columns and the test assertions; reconstructSource(frameId: number) consistent across store + integration test; barrel exports name RawArchive, hashRaw, RawArchiveRow, ArchiveInput in both hive-mind-core and core. ✓
