# Rebuilding Leo's Knowledge Database
## Outcome
Leo should improve by compiling durable source material and reviewed changes
into Postgres. Repeatedly changing prompts or retraining the chat behavior is
not the knowledge system.
There are two different rebuilds:
1. **Exact recovery** restores the current canonical database from a verified
snapshot. This is working now.
2. **Semantic recompilation** starts from the retained source corpus and the
reviewed change ledger, then reproduces the canonical rows. This is partly
recoverable but is not yet complete.
## Exact Recovery: Working
Run:
```bash
.venv/bin/python ops/run_local_canonical_postgres_rebuild.py \
--dump /private/path/teleo-canonical.dump \
--source-manifest /private/path/source-manifest.jsonl \
--output /tmp/teleo-canonical-rebuild-receipt.json
```
The 2026-07-13 live canary restored a fresh, network-isolated Postgres in 3.81
seconds and then removed it. The restored target matched the source across all
39 manifest tables and all 52,164 rows, with no schema, data, constraint, role,
or performance mismatch. Key rows included:
- 1,837 claims;
- 4,145 sources;
- 4,670 claim-evidence links;
- 4,916 claim edges;
- 17 reasoning tools;
- 26 proposals.
This is the fastest disaster-recovery path. It does not require Leo to
re-extract or relearn the corpus.
## Source Recompilation: Current Evidence
Read-only VPS inspection found two retained June import runs. Both point to the
Forgejo-era workspace at `/opt/teleo-eval/workspaces/main` and retained
inventory JSONL files under `/opt/teleo-eval/kb-import/`.
The database still retains:
- `kb_stage.import_runs` for the two inventories;
- staged claims, sources, claim-source links, and claim edges;
- `kb_stage.canonical_mappings` from legacy keys to canonical UUIDs;
- mappings for 1,807 of 1,837 canonical claims;
- mappings for all 4,145 canonical sources.
For the 1,807 mapped claims, current canonical type, text, status, confidence,
tags, and creator match the retained staged rows exactly. Creation timestamps
also follow a recoverable rule: use the legacy timestamp when present and the
mapping timestamp for the eight rows that had no legacy timestamp.
The simple retained-row joins currently reproduce:
- 4,254 of 4,670 canonical evidence links;
- 4,878 of 4,916 canonical edge rows can be accounted for by a staged relation;
historical duplicate multiplicity still needs an explicit replay rule.
The remaining gaps are concrete rather than mysterious:
- 30 claims were created after or outside the mapped import;
- 284 mapped source rows do not have a matching retained `staged_sources` row
and need the original source-synthesis rule or an explicit genesis record;
- 416 evidence links need source-synthesis or later-change provenance;
- 38 edge rows need later-change receipts or explicit replay records;
- old applied proposal rows do not describe every historical canonical write.
This proves that most of the initial database came from the retained file-KB
import path. It does not yet prove a clean blank-database recompile.
## Target Compiler
The durable rebuild model is:
```text
immutable source corpus + file hashes
-> deterministic inventory and classification
-> staged claims, sources, evidence links, and edges
-> stable canonical ID mapping
-> review decisions
-> append-only accepted apply payloads and receipts
-> canonical Postgres
-> render/sync/restart
-> answer benchmark
```
Use the current verified snapshot as **genesis epoch 1**. Preserve its dump,
manifest, source commit, inventory files, mappings, and aggregate rebuild
receipt. Every accepted change after that epoch must carry a replayable strict
apply payload and row-level postflight receipt. This prevents the historical
gap from growing while the old import rules are reconstructed.
The existing local ingestion canary already proves one hash-bound document
fixture can become a normalized `pending_review` proposal without touching
canonical rows. The existing full-data clone canary proves a reviewed packet
can create source, claim, evidence, and edge rows and affect later reasoning.
The next capability is to join those into a corpus runner and replay ledger.
## Definition Of Working
Semantic recompilation is complete only when all of these pass:
1. A command creates a blank database from the retained source corpus plus the
reviewed ledger.
2. Schema, constraints, roles, table counts, row hashes, and key query results
match the canonical manifest.
3. Every canonical row traces to a genesis import record or a reviewed apply
receipt.
4. A new document can be hash-captured, extracted into grounded candidates,
deduplicated, staged, reviewed, applied in a disposable clone, and read back.
5. After render/sync and restart, Leo answers the related broad question using
the new rows and cites the source chain.
Until then, exact snapshot recovery is production recovery; source
recompilation is an active build capability, not a finished claim.

# Local Canonical Postgres Rebuild Canary
Generated UTC: `2026-07-13T08:34:54.016399+00:00`
Status: **pass**
## Result
- Total command time: `3.809726s`
- Named database ready: `0.781077s`
- `pg_restore`: `1.026398s`
- Manifest capture and parity comparison: `1.229484s`
- Cleanup: `0.088110s`
- Dump bytes: `13,462,116`
- Dump SHA-256: `8a217e32bf6c83cb2b629e5ca5f91fc57f759e5010d9c40babe0d13c9a450822`
- Source manifest SHA-256: `d077f859b5f8ece908c61958a90914272ddc6fb9930df3b97d2ad2ac85b8e39a`
## Parity
- Manifest tables: `39/39`
- Total rows: `52,164/52,164`
- Table mismatches: `0`
- Column, constraint, function, index, policy, schema, sequence, trigger,
type, and view hash mismatches: `0`
- Application role mismatches: `0`
- Performance threshold failures: `0`
Key restored rows:
| Object | Rows |
|---|---:|
| `public.claims` | 1,837 |
| `public.sources` | 4,145 |
| `public.claim_evidence` | 4,670 |
| `public.claim_edges` | 4,916 |
| `public.reasoning_tools` | 17 |
| `kb_stage.kb_proposals` | 26 |
## Isolation And Cleanup
- Docker image: `postgres:16-alpine`
- Network mode: `none`
- Postgres data directory: `tmpfs`, no persistent Docker volume
- Named-database readiness used an actual `psql -d teleo` connection
- Production database touched: `false`
- Container absence after cleanup: `true`
- Independent label-filtered orphan check: no containers found
## Command
```bash
.venv/bin/python ops/run_local_canonical_postgres_rebuild.py \
--dump /private/path/teleo-canonical.dump \
--source-manifest /private/path/source-manifest.jsonl \
--output /tmp/teleo-canonical-rebuild-receipt.json
```
This proves fast exact recovery from the canonical snapshot. It does not claim
that the whole database can yet be semantically recompiled from raw documents
and reviewed change records alone.
