## Summary
Add `buzz repos default-branch get/set` and the relay operation it
needs. Git push changes branch tips but cannot select the server's
symbolic HEAD. This selects an existing branch without deleting
branches, moving refs, or changing packs.
- Reuse immutable Git manifests and captured-ETag CAS; concurrent
pushes/default changes conflict, including stale no-ops.
- Require request-specific NIP-98, body binding, fail-closed replay
protection, host tenancy, current channel membership and
repository-management authority. Push/project roles alone are
insufficient.
- Send the CLI mutation once, without redirects; ambiguous delivery
retains the observed digest and is non-retryable.
- Document the narrow HTTP exception to Nostr-first, delegation scope
and admission-time ACL revocation. Kind:30618 remains derived; the
manifest CAS is authoritative.
- Register the Postgres/Redis/MinIO route and fresh-clone tests in the
existing Backend Integration lane.
## Review fixes — `7457bda50afa6b52e36315572fa96928b2e21db6`
- Reject signed valueless `payload` tags when verifying a body; preserve
the shared verifier's intentional absent-payload compatibility. The real
settings route now proves 401, unchanged manifest pointer, and unchanged
kind:30618 event IDs for malformed and other invalid credentials.
- Require a nonempty returned branch and `head == refs/heads/{branch}`;
SET additionally requires the returned branch to equal the attempted
branch. Malformed/mismatched mutation responses remain non-retryable
`DeliveryUnknown`, retaining the attempted branch and original digest.
Invalid reads fail before any POST.
- Strengthen the later-push/fresh-clone regression to select
`release/v1` while `main` exists.
## Verification
At `7457bda50afa6b52e36315572fa96928b2e21db6`:
- Full pre-push passed (all 14 Rust test groups, serialized Tauri
tests/clippy, file-size and branch-skew gates; 522 seconds). No hooks
disabled.
- All four isolated Postgres/Redis/MinIO settings tests pass, including
real Smart HTTP `ls-remote --symref` and fresh clone on `release/v1`.
- All 15 focused NIP-98 verifier tests and three default-branch CLI
tests pass; malformed credentials and missing-branch responses were
reproduced failing before the fixes.
- Five targeted mutants are killed: restoring the valueless-payload
bypass, weakening canonical HEAD validation, accepting an empty branch,
dropping requested-branch confirmation, and omitting hydrated HEAD for
the selected non-main branch. Mutations ran in a separate worktree and
target directory; original patch bytes were verified restored.
- `cargo clippy -p buzz-auth -p buzz-cli -p buzz-relay --all-targets --
-D warnings`, formatting, diff and file-size checks pass on the fixed
tree.
Earlier validation at `bb195b140`: seven Git authorization database
regressions and 28 existing transport tests passed (three infrastructure
cases in that module not selected); four mutations killed
management/replay/CAS/redirect regressions. Full pre-push passed with
`RUST_TEST_THREADS=1` (all 14 Rust groups, Tauri clippy and 3,173 tests,
size/branch-skew gates). Serial execution avoids an unrelated
process-global Desktop discovery counter flake; no hooks disabled or
Desktop changes.
Carl and Jude's review findings are addressed in the new head; **fresh
reviewer and exact-head security confirmation remain required**. The
earlier source review is not approval of this revision. No claim of
green new-head CI.
## Rollout
Merge and **deploy the relay support first**, then build/use the updated
CLI and explicitly set/verify the desired default. No schema migration.
This PR does not deploy anything or change a live repository.

## Why
NIP-29 membership authorization for kinds 9000, 9001, and 9022 was
embedded in a large async handler, requiring Postgres and Redis to test
and repeating the last-owner rule across five call sites. This addresses
[TheSentinel454/buzz#24](https://github.com/TheSentinel454/buzz/issues/24)
without adding the broader state/repository abstraction suggested there
because HTTP and WebSocket writes already share ingestion.
## What
- Extract pure, typed membership authorization decisions while leaving
database reads and mutations in `validate_admin_event`.
- Preserve existing client-visible errors and independent database
last-owner safeguards.
- Collapse five last-owner policy restatements into one predicate and
share the identical self-departure policy.
- Include the relay decision modules in `just test-unit`, so these tests
execute in CI.
## Risk Assessment
Medium-low. This touches production relay authorization, but
intentionally preserves wire behavior and database defense in depth;
exhaustive decision tables and relay-backed tests cover the affected
paths.
## Simplification
This removes repeated policy from the orchestration path and makes the
rule set directly testable without introducing a repository trait or
second transport path.
## Verification
Verified at `15255a090797f85874921120003c645962fefaed`:
- `just test-unit` — all 10 package summaries passed. An initial run hit
two unrelated timing-sensitive `buzz-acp` failures; the complete retry
passed 905/905 in that package.
- `cargo fmt --all -- --check`
- `cargo clippy --workspace --all-targets -- -D warnings`
- `just file-size-check` — 10/10 policy tests passed.
- `just security-review-check` — 13/13 tests passed.
- Push preflight — `push-head-scope`, `branch-skew`, `file-size-check`,
`rust-tests`, and `desktop-tauri-checks` passed.
- Blox Postgres relay lane — 84/84 at the byte-identical source patch;
full live `e2e_relay` behavior matched the clean base (45 pass and the
same pre-existing kind:9002 failure on each).

## Why
The monolithic CI workflow is a frequent merge-conflict hotspot.
Splitting cohesive domains into same-repository reusable workflows keeps
one centrally filtered entry point while letting Rust, desktop,
relay/PostgreSQL, client, and security CI evolve independently.
## What
- Keep `ci.yml` as the only push/pull-request orchestrator with
unchanged concurrency and path detection.
- Move 18 execution jobs into five `workflow_call`-only domain workflows
without changing their runners, steps, matrices, caches, artifacts,
permissions, or timeouts.
- Keep the relay artifact producer with desktop integration, the
complete PostgreSQL lane, and relay E2E consumers.
- Preserve all 12 existing required GitHub Actions contexts through
lightweight top-level compatibility gates, so the repository ruleset
does not need to change.
- Update the Rust-cache contract to follow Unit Tests into
`_ci-rust.yml`.
## Risk Assessment
CI-only change with moderate workflow-orchestration risk. The main risks
are reusable-workflow output propagation, skip behavior, and visible
check naming; the old required names remain explicit top-level jobs, and
the draft will stay open until an exact-head GitHub Actions run and
independent review are complete.
