Summary

  • reserve kind 30179 for owner-private managed-agent aggregates
  • define the fail-closed owner-self NIP-44 v2 envelope and versioned payload codec
  • bind runnable identity/configuration to complete signed 30175/30177 recovery projections
  • validate NIP-OA owner→agent attestations and reject self-attestation
  • document NIP-PMA authority, migration prerequisites, privacy, and deployment order
  • keep generic relay ingest closed until private storage and atomic aggregate CAS exist

Safety boundary

This is the inert protocol/codec slice only. It does not publish secrets, change agent authority, migrate local records, or enable kind 30179 ingestion. The relay regression test proves generic EVENT ingest still rejects the kind.

The finalized migration plan adds later prerequisites for relay-private storage/CAS, runtime lease/fencing, Desktop cutover, and harness authentication. Those belong in staged follow-up PRs rather than expanding this inert foundation.

Validation

At commit 67f0ea4ebb8d3ccba3a3eb9374e89a7178913f74:

  • cargo test -p buzz-core — 246 unit + 2 doc tests passed
  • cargo test -p buzz-relay private_managed_agent_kind_remains_rejected_until_atomic_ingest_exists — passed
  • push hooks: Rust tests and desktop checks passed (2145 desktop tests passed, 14 ignored)
  • cargo fmt --all -- --check
  • git diff --check

Review

Princess Donut cleared security/data integrity with no remaining high/medium findings. Mongo cleared migration compatibility and wire grammar. The later runtime lease/fencing protocol was also adversarially cleared as a plan; implementation slices still require independent evidence before activation.

Deterministic plaintext/signed-projection/auth-tag interoperability vectors remain a valuable follow-up, not an S0 merge gate; random NIP-44 ciphertext is intentionally not snapshotted.

Reserve the owner-private managed-agent event kind and define its
fail-closed NIP-44 envelope, aggregate payload, projection recovery
bindings, NIP-OA validation, and protocol contract. Keep generic relay
ingest closed until privacy storage and atomic CAS are implemented.

Pass the serialized payload directly to NIP-44 encryption so current
Clippy does not reject the needless generic-argument borrow.

Keep Debug available for aggregate diagnostics while replacing private
identity and configuration contents with explicit redaction markers.
Add coverage proving keys, auth tags, environment values, and backend
secrets cannot leak through the enclosing payload formatter.

## What

Relay-only carve-out of the ingest half of #4999: generic EVENT ingest
now accepts kind:30179 (NIP-PMA private managed-agent config). One file,
`crates/buzz-relay/src/handlers/ingest.rs`, 16 insertions / 15
deletions; **two semantic lines**, byte-identical to the ingest hunk of
#4999 at `6f486e88`:

1. `required_scope_for_kind`: 30179 requires `Scope::UsersWrite` — same
arm as its public sibling 30177 and the other owner-authored NIP-AP
kinds.
2. `is_global_only_kind`: 30179 is owner-global, keyed `(pubkey, kind,
d-tag)`; a stray `h` tag must not channel-scope it.

The rest is import reflow plus replacing the guard test with a positive
one (`private_managed_agent_kind_is_owner_scoped_global_user_data`:
asserts UsersWrite scope, global-only, no h-channel scope).

## Why the guard test can be retired

The removed test
(`private_managed_agent_kind_remains_rejected_until_atomic_ingest_exists`)
pinned a stated precondition: *"must not enter generic EVENT ingest
before privacy and aggregate CAS deploy."* Both halves are resolved:

- **Privacy** — the author-only read gates for 30179 shipped to main
with #4593: `AUTHOR_ONLY_KINDS` membership, `req.rs` pre-filter + result
gates, `count.rs`, `event.rs` fanout, and the bridge pre-filter
(`bridge.rs:999-1000` returns `restricted: author-only kinds require
authors=[self]` / 403). Only the author can read the event back.
- **Aggregate CAS** — #4999 settled generation as **advisory**: the `g`
tag is shape-validated, never relay-enforced. Last-write-wins per
coordinate is the contract of record (see the kind:30179 contract blurb
in #4999), so no CAS mechanism is pending on the relay side.

## Why this is inert to existing relays and clients

- No production desktop code on main authors kind:30179 — the codec
(`private_managed_agent.rs`) has zero non-test callers. This PR accepts
a kind nobody can produce yet.
- Content is opaque NIP-44 ciphertext to the relay; the relay never
decrypts it.
- Reads remain author-only via the already-shipped gates above.
- Storage is the standard parameterized-replaceable path already
exercised by kinds 30175–30178. No schema, config, or migration changes.

## Testing

- Full `buzz-relay` package suite at this commit: 859 passed, 1 failed —
`api::mesh_demo::tests::demo_join_forwarded_arm_round_trips_echo` (504
vs 200), which **reproduces identically on clean main `769ac70b`** with
this change stashed; pre-existing/environmental, not introduced here.
- New positive ingest test passes.
- Pre-push hooks green (branch-skew, rust-tests, desktop-tauri-checks).

## Relationship to #4999

#4999 (relay-primary agent config, desktop half) stays DO-NOT-MERGE
pending live relay receipts + real CI; once this lands and deploys, its
live test simplifies to plain `desktop-standalone` against the real
relay, and #4999 rebases to drop its now-duplicate ingest hunk
(identical bytes → trivial rebase).

Originating thread:
buzz://message?channel=06f13ed3-0557-4ac2-922c-1545dd00bf97&id=2a43b3b4933a2ea78b77088619251c061355f9b7b6dc29ea0d702193f2344149


## Brownfield FTS note (review findings, operator-ruled non-blocking for
this PR)

Max and Sami independently identified that the FTS privacy skip-set is
regime-dependent: migration 0008 installs the positive allowlist (`kind
IN (0, 9, 40002, 45001, 45003)`) **only on an empty events table**; an
already-populated database keeps the 0001/0005 negative skip-list
(wrapped by 0014 to add 30350), which omits 30179 — so on such an
installation this PR admits 30179 rows whose NIP-44 ciphertext gets
indexed by `to_tsvector`. Sami measured both regimes against real
Postgres (brownfield: 30179 INDEXED; fresh: NULL) and demonstrated the
existing drift test only exercises the fresh regime.
`schema/schema.sql:222`'s canonical literal is also the negative list
and omits 30179. Migration dates put any relay deployed with data before
0008 landed (2026-07-13) in the brownfield class.

**Scope of exposure (Sami's trace):** not a content leak —
`event_visible_to_reader` / `is_author_only_event` gates hold on both
search surfaces (`req.rs:725`, `bridge.rs:1770`), so foreign readers
receive nothing. Lost is the storage-level NULL-tsv backstop plus FTS
page budget burned on post-filtered hits.

**Operator ruling (Tyler, events `1472e5b6`, `cbd368ed`):** ship this PR
without an exclusion migration. Safety argument that makes this sound
rather than merely accepted: main has **zero non-test 30179 writers**
until #4999's desktop half deploys — no 30179 rows can exist, so nothing
can be indexed in any regime while this PR is the only half live.



**Additional review characterizations (Sami, non-blocking, on the
record):**
- *Behavioral delta enumerated:* routing triple
(`required_scope_for_kind` / `is_global_only_kind` /
`requires_h_channel_scope`) compared for all 65,536 kinds at base
`769ac70b` vs head `77eeba6e` — exactly one row differs (30179). No
other kind or client changes behavior.
- *"SQL visibility before LIMIT" (NIP-PMA step 2):* no
`AUTHOR_ONLY_KINDS` pushdown clause exists in `buzz-db` (only
`SHARED_GATED_KINDS` has one). Author-only kinds are protected by the
pre-filter (`author_only_filters_authorized`) plus post-filter omission;
mixed-kind filters can burn candidate-page budget on discarded rows.
Pre-existing and identical for 30300/30350 — not introduced here; noted
so the NIP's step-2 checkbox is not read as fully ticked.
- *Envelope validation gap:* 30179 is the only parameterized-replaceable
kind at ingest with no per-kind envelope validator (codec grammar checks
run in the desktop writer, not the relay). Generic limits only (256 KiB,
±15 min, pubkey==identity, d-tag bound). Self-inflicted footgun bounded
to the author's own coordinate — candidate companion to the exclusion
migration in the #4999 rebase, deliberately not added here.

**Bound follow-up (required before/with the #4999 desktop half):** a
0014-shape additive migration (`pg_get_expr` capture + `CASE WHEN kind =
30179 THEN NULL ELSE (<existing>) END` wrap), add 30179 to the
`schema/schema.sql:221` literal, and a brownfield-regime variant of the
FTS drift test, per Sami's finding. Deploy-time spot check if ever
wanted: `SELECT pg_get_expr(d.adbin, d.adrelid) FROM pg_attrdef d JOIN
pg_attribute a ON a.attrelid = d.adrelid AND a.attnum = d.adnum WHERE
d.adrelid = 'events'::regclass AND a.attname = 'search_tsv';`
