Ships the request side of joining a gated scope, completing the §22.8 pair
(S4 shipped the invite half). A user who knows a project/collection exists
asks to join it naming a desired role; the request fans out to that scope's
Owners across the subtree (the cross-collection inbox, §22.11), who accept
(writing the memberships row via memberships.grant) or decline. Built by
analogy to §28 contribution_requests + the S4 memberships surface.
Backend
- migration 032: join_requests (scope_type ∈ {project,collection}, scope_id,
requester, requested_role, message, status, granted_role); one-open-per
(scope, requester) partial unique index. Additive — no rebuild.
- api_join_requests.py: GET join-target / POST join-requests / POST
{id}/accept / {id}/decline under /api/scopes/{scope_type}/{scope_id}/.
Accept grants via memberships.grant; the request POST does not require the
scope be readable (that is how one joins a gated scope).
- notify: fan_out_join_request (subtree-Owner enumeration via
_scope_owner_user_ids), notify_join_decided, 3 render_summary cases.
- auth.effective_role_at_scope — scope-grain twin of effective_scope_role,
folding global → project for a project target.
- api_collections: viewer.can_request_join on the project + collection blocks.
Frontend
- api.js join verbs; JoinRequestModal; "Request to join" affordance in the
collection directory + catalog footer; JoinRequestRow in the inbox.
Tests: backend test_join_requests_vertical (11) + test_migration_032 (5);
frontend api.joinrequests + CollectionDirectory cases. 546 backend / 36
frontend green.
Per docs/design/2026-06-05-three-tier-projects-collections.md Part E (S6) and
SPEC.md §22.8 / §22.11. Closes the request-to-join item flagged open at
0.45.0; per-type surfaces (§22.4a items 1 & 3) remain the last S6 item.

The Owner-only scope-role grant surface (Part E S4 / Part C.2). An Owner
grants {owner, contributor} at a scope their reach covers — the project or
one collection within it — to an existing account looked up by email; the
grant writes a `memberships` row immediately and §15-notifies the grantee
(direct grant, no accept round-trip — the C.2 scenarios name existing
accounts and write the row directly).
- auth.can_invite_at_project / can_invite_at_collection — the Owner-reach
invite gates (is_project_superuser / is_collection_superuser).
- memberships.py — grant (with the C.2.6 broader-supersedes-narrower prune,
preserving a stronger child grant — no negative override), revoke, list,
user_by_email.
- api_memberships.py — GET/POST/DELETE /api/projects/:id/members, the single
POST keying on optional collection_id so the invite UI's one control maps
to one endpoint; reach bounded by the inviter's Owner reach (C.2.3);
contributors refused (C.2.4); a pending grantee's row is recorded but
confers no write (C.2.7, the §6 floor).
- notify.notify_scope_role_granted + render_summary — the §15 personal-direct
notification naming the project and role.
- api_collections — surface viewer capabilities (can_create_collection,
can_invite, can_contribute, role) on the project/collection GETs to drive
the C.3 role-aware empty states.
Acceptance: test_s4_invitations_vertical.py covers C.2.1–C.2.7 over the HTTP
surface + resolver, plus the C.3 (@S4) capability flags. Full suite green
(504 passed).

Extends the v0.26.0 (#28 Part 1) read-time scanner into three buckets in
one pass — active link (Part 1), pending-RFC contribute offer (Part 3),
create-RFC offer (Part 2) — precedence active > pending > candidate. The
backend still emits only structured segments (never HTML), so the surface
stays XSS-safe by construction.
Part 2 — create-RFC offers: a multi-word tag from the #27 taxonomy with no
defining RFC renders, for a create-rights viewer, as an inline "+ create
RFC" affordance that opens the propose modal pre-filled (?propose=<term>;
ProposeModal gained initialTitle). Conservative multi-word gate; broader
heuristics + the Haiku path are deferred.
Part 3 — contribute-to-pending offers: a term matching a super-draft
renders, for a signed-in non-owner, an "ask to contribute" affordance with
the owner's display name. It opens a 3-field request form (who/why/optional
use-case); submitting lands a contribution_requests row (migration 024) and
one actionable §15 notification per owner (new kind
contribution_request_on_pending_rfc, personal-direct). The owner's inbox
shows who/why/use-case inline with Accept/Decline. Accept fires #12's
owner-invite flow with the requester as invitee and echoes a notification
back; decline notifies the requester. Pre-merge idea PRs are out of scope.
New endpoints: GET /api/rfcs/{slug}/contribution-target,
POST /api/rfcs/{slug}/contribution-requests,
.../{id}/accept, .../{id}/decline. The invite issue path was refactored
into one reusable api_invitations.issue_invitation(...) chokepoint shared
by the manual invite endpoint and Part 3's accept.
Tests: 9 new (3 scanner-bucket unit + 6 e2e). Full suite 374 passing.

Roadmap item #3. An RFC's main view now carries a discussion surface
distinct from PR comments and from branch chat. The substrate is the
existing threads/thread_messages tables — rows with branch_name IS NULL
scope to the RFC's main view; the schema already permitted that shape,
v0.5.0 is the first build to write it. Five new endpoints under
/api/rfcs/<slug>/discussion/..., a new RFCDiscussionPanel right-column
component used when branchParam === main, SPEC §10.10 settling
discussion-vs-contribution, and §17 listing the new routes. Notification
routing reuses the existing chat_message_in_participated_thread /
chat_reply_to_my_message event kinds with branch_name=null on the
fan-out row; a distinct event_kind is a §19.2 candidate. Anonymous
viewers can read; writes require contributor — v0.6.0's item #4 will
harden adjacent gates. No schema migration; minor bump, no operator
action required beyond rebuild and restart.
