# Workspace preprocessing CLI contract
`thothctl` is the only supported host entrypoint for workspace preprocessing.
## Invocation
```text
thothctl --installation <absolute>/thothii-installation.yaml workspace inspect
--workspace <id> [--json]
thothctl --installation <absolute>/thothii-installation.yaml workspace preprocess dwh
--workspace <id> [--resume <32hex>] [--json]
thothctl --installation <absolute>/thothii-installation.yaml workspace schema suggest-fks
--workspace <id>
[--from-sql <regular-file>]... [--assume <column=table>]...
[--output <new-file>] [--json]
thothctl --installation <absolute>/thothii-installation.yaml workspace schema check
--workspace <id>
[--annotations <regular-file> --reviewed-candidates <sha256:hex>]
[--json]
thothctl --installation <absolute>/thothii-installation.yaml workspace schema accept
--workspace <id> --run <32hex> --yes [--json]
thothctl --installation <absolute>/thothii-installation.yaml workspace index-schema
--workspace <id> [--json]
thothctl --installation <absolute>/thothii-installation.yaml workspace preprocess evidence
--workspace <id> [--dry-run] [--resume <32hex>] [--json]
thothctl --installation <absolute>/thothii-installation.yaml workspace preprocess run
--workspace <id> [--resume <32hex>] [--json]
thothctl --installation <absolute>/thothii-installation.yaml workspace vector inspect
--workspace <id> [--json]
thothctl --installation <absolute>/thothii-installation.yaml workspace vector rebuild
--workspace <id> --collection <name> --confirm <name> --destroy [--json]
```
## Qdrant collection lifecycle (P4)
- `workspace vector inspect` reports the descriptor-owned Qdrant collection contract
(name, dimensions, distance, keyword indexes) **without mutation**.
- `workspace vector rebuild` deletes and recreates the descriptor-owned collection
with the exact contract (1024 dimensions, cosine distance, the 8 required keyword
payload indexes) under guards:
- `--collection <name>` must equal the descriptor's `semantic_index.vector_store.collection`;
- `--confirm <name>` must equal `--collection` (exact repetition);
- `--destroy` is required to confirm the destructive operation;
- the operator refuses any other combination with exit code 2 (usage).
- Self-heal at session admission: a missing collection is created and missing
keyword indexes are added by the shared collection manager; incompatible
dimensions/distance/index types are never mutated (`semantic_index_incompatible`).
- The operator path (`workspace-maintenance.js vector-inspect|vector-rebuild`)
performs the guarded rebuild; rebuild state is written before deletion and the
collection is verified after recreation. No prefix matching or global Qdrant
mutation is performed.
```
## Curated FK annotations (P5)
- The canonical curated annotations file is `<workspace-id>/schema/annotations.yaml`, a regular
Git blob at the same commit as the descriptor. Absence is compatible (empty canonical set +
warning); symlinks, trees/gitlinks, oversized (>16 MiB), non-UTF-8, and malformed objects are
refused at activation.
- Activation synchronizes the blob to the immutable revision-qualified root
`/data/sessions/<id>/revisions/<commit>/artifacts/mschema/annotations.yaml` with a restrictive
mode and an adjacent ownership manifest `{ workspace, commit, blobId, contentDigest,
destination }`. Pinned runtimes resolve annotations from `paths.annotations_root`.
- `workspace schema accept --run <id> --yes` is the only human FK review primitive: after
commit/push/pull, it reads the current synced blob, validates it with the harness parser against
the physical schema and the recorded candidate digest, and records
`{ reviewedCandidatesDigest, annotationsDigest, workspaceRevision, blobId }`. `--yes` is
required; an empty file, an unknown run, a malformed blob, or a non-matching candidate fails
closed without recording a review. `schema check` alone is not evidence of human review.
- `preprocess run` continues only with the exact accepted blob digest and a compatible reusable
DWH binding; otherwise it records a new review checkpoint.
## Validation
- `--installation` is mandatory and absolute.
- `--workspace` is mandatory exactly once and must match `[a-z][a-z0-9-]{2,62}`.
- `--resume` values must be 32 lowercase hex characters.
- `--json` may be supplied once.
- `schema suggest-fks`
- allows at most 32 `--from-sql` files;
- each SQL file must be a canonical regular file, UTF-8, non-symlink, max 1 MiB;
- total SQL ingress must not exceed 16 MiB;
- allows at most 256 `--assume` values, each `column=table`, max 256 bytes;
- `--output` must name a new canonical path; existing targets are refused.
- `schema check`
- `--annotations` and `--reviewed-candidates` are all-or-nothing;
- annotations must be UTF-8, canonical, non-symlink, max 16 MiB;
- `--reviewed-candidates` must match `sha256:<64 lowercase hex>`.
- `schema accept`
- `--run` is mandatory and must be 32 lowercase hex characters;
- `--yes` is mandatory and may be supplied once;
- `--annotations`/`--reviewed-candidates`/`--from-sql`/`--assume` are not accepted.
- Unknown flags, passthrough separators, and shell fragments are rejected before Docker runs.
## Container boundary
`thothctl` resolves the selected `core` image from the rendered installation, converts it to an immutable local image ID, writes a one-shot final override that pins both `core` and `workspace-maintenance` to that ID with `pull_policy: never`, and runs only:
```text
docker compose run --rm --no-deps --no-TTY --name <owned-name> workspace-maintenance <fixed-command>
```
The request is streamed as one schema-versioned JSON document over stdin. Public stdout is always one schema-versioned JSON result; human mode is rendered from an allowlisted subset of that same result.
## Public JSON result
```json
{
"schemaVersion": 1,
"status": "succeeded|unchanged|dry_run|blocked|failed",
"code": "ok|workspace_not_found|workspace_not_activatable|binding_missing|preprocessing_conflict|preprocessing_resume_mismatch|manual_review_required|evidence_materialization_required|effective_config_mismatch|semantic_index_incompatible|annotation_invalid|egress_policy_refused",
"workspaceId": "abc",
"workspaceRevision": "1234567890abcdef1234567890abcdef12345678",
"descriptorBlob": "sha256:<64 lowercase hex>",
"operation": "inspect|preprocess-dwh|schema-suggest-fks|schema-check|index-schema|preprocess-evidence|preprocess-run",
"runId": "<optional 32hex>",
"childRuns": {"stage": "<optional 32hex>"},
"completedStages": ["stage"],
"counts": {"name": 1},
"artifactIdentities": [{"kind": "fk_candidates", "digest": "sha256:<64 lowercase hex>"}],
"warnings": ["safe warning"]
}
```
`thothctl --json` parses the operator stdout strictly and re-encodes only the public fields above.
## Exit codes
- `0`: `succeeded`, `unchanged`, or `dry_run`
- `3`: `blocked`
- `2`: host-side grammar or local file safety failure
- `1`: operational failure or operator-reported `failed`
