Follow-up review pass on #884.
- add `Case.missing_status` so a permissive missing-name position asserts the
status it should actually get (404, or 200 for the no-op removal) instead of
`!= 422`, which also passed on a 5xx — the same hole already closed in the
squatter assertion
- require it whenever `refuse_missing` is False, and require its absence when
True, so the policy table can't drift from the assertion
- repoint a stale allow-reason at POST /scopes/{scope_id}/sessions/list; the GET
it named was removed
- document the membership list's ordering under `reverse`
Review response for #884.
Security:
- gate `SessionCreate.scopes` behind a workspace-level key; the session-create
route is self-authorizing, so a peer- or session-scoped token could mint scope
peers and join sessions to scopes it had no access to via `POST /scopes`
- refuse a reserved-but-nonexistent name in two observed positions that used the
permissive guard: chat `target` and session-context `peer_target`. Both let a
caller act on `scope.X` before it existed, then create the scope
Facade:
- exclude scope peers from `GET /sessions/{id}/peers` and refuse the membership
-config read for a real scope, matching its write side
- replace `GET /scopes/{id}/sessions` with `POST /scopes/{id}/sessions/list`
returning `Page[Session]`; the add route now returns 204. Membership was
unbounded on both, while every other list surface paginates
- rename `crud.get_scope` to `get_scope_or_raise`
Tests:
- add a missing-name axis to the route-policy table (`Case.refuse_missing`), which
is what surfaced the two guard gaps above
- delete 14 hand-written tests the table now enumerates; 52 -> 39 functions in
test_scopes.py with more cases covered
- tighten the squatter assertion from `!= 422` to `< 400`, which was passing on 5xx
- assert the FastAPI-internals traversal still derives positions, so a framework
upgrade can't silently empty the suite
Docs:
- drop internal ticket and RFC references from the published OpenAPI descriptions
and surrounding comments; state the behavior instead
- move implementation reasoning out of the `PUT /peers/{id}` docstring, which
FastAPI publishes, into a comment
Three coupled changes to the scopes facade.
1. `PeerCreate` no longer gates internal lookups. It exists to validate a new,
user-supplied peer id at the API boundary, but crud used it as a DTO for
names that already exist, so any name outside RESOURCE_NAME_PATTERN raised a
raw pydantic ValidationError — which is not a HonchoException, so it fell
through to the catch-all handler as an HTTP 500. Adds `PeerSpec` (same
fields, no charset pattern) as `PeerCreate`'s base, widens
`get_or_create_peers` to accept it, and changes `get_peer` to take a plain
str. All 13 construction sites converted; the create route keeps full
validation.
This unbreaks the Dreamer: DreamScheduler passes `collection.observer`
straight into the specialist preflight, and scope peers have
`observe_others=true`, so every `(scope.x, peer)` dream died there — the
feature scopes exist to enable. It also fixes a pre-existing bug unrelated
to scopes: a peer named `alice.smith` (legal before d429de0e5338, which
validated names by length alone) 500s on message create, session peer add,
and peer update.
2. The `kind` flag moves from `configuration` to `internal_metadata`.
`configuration` is user-writable — `PeerCreate`/`PeerUpdate` accept a
free-form dict and `update_peer` replaces it wholesale — so a legitimate
`{"observe_me": true}` update silently dropped the flag, and a forged
`{"kind": "scope"}` injected an ordinary peer into `POST /scopes/list`.
`internal_metadata` appears in no API schema. `observe_me: false` stays in
`configuration`, where it belongs.
3. Scope identity requires prefix AND flag, via `is_scope_peer()` and
`scope_peer_clause()`. Neither half is forgeable: the prefix sits outside
RESOURCE_NAME_PATTERN, `internal_metadata` is unreachable. Usage-site guards
become flag-based so a legacy peer merely occupying the namespace keeps
working rather than 422-ing on its own traffic; peer create and update stay
name-based, since those must stop new names entering the namespace.
`update_peer` now returns 422 instead of 500.
Also swaps the reserved prefix from `scope__` to `scope.`: `_` is inside
RESOURCE_NAME_PATTERN, so any tenant could already own a `scope__x` peer.
No DB migration — `internal_metadata` already exists on `peers`, and no scope
peers exist in any deployment yet.

New /v3/workspaces/{workspace_id}/scopes facade (workspace-level auth;
peer- and session-scoped keys are rejected):
POST "" create-or-get (201/200)
POST /list paginated scope list
GET /{scope_id} single scope
POST /{scope_id}/sessions add memberships
DELETE /{scope_id}/sessions/{session_id} remove membership
GET /{scope_id}/sessions list member session ids
- crud/scope.py: get_or_create_scopes stamps the backing peer with
{"kind": "scope", "observe_me": false} and refuses to adopt a
legacy peer occupying the reserved name without the flag (409)
- memberships are session_peers rows with observe_others=true /
observe_me=false — identical to a hand-built observer peer
- SessionCreate.scopes: create-or-get each scope peer and add the
membership at session creation (the no-backfill common path)
- crud/session.py: public upsert_session_peers wrapper so the facade
bypasses the route-level guardrails without reaching into privates
Backfill of pre-existing documents and reconciliation on removal land in
DEV-1999; membership only affects messages ingested after the change.
Part of DEV-1997 (Scopes RFC DEV-1970).
