Subject: [PATCH 03/76] fix(desktop): repair the Windows notification shim's
 false denial on read

On Windows the notification plugin's injected shim stamps `denied` at
startup without ever consulting the backend, whose `permission_state()`
returns `Granted` unconditionally on desktop. Its bootstrap short-circuits
on the `__TEMPLATE_windows__` literal and compares its own freshly
initialised `'default'` against `'granted'`.

`getDesktopNotificationPermissionState()` trusted that value, so the
mount-time read reported `denied` and the settings effect turned
`desktopEnabled` off and persisted it on every launch -- which is why
fixing only the enable path leaves a Windows user re-enabling alerts
after each restart.

Repair the value at the read instead of reporting it. Inside the Windows
Tauri app a `denied` reading is never a real denial, and
`requestPermission()` is the only call that reaches the backend and
rewrites the shim's cached value. It is self-limiting: the next read
short-circuits as `granted` and never requests again.

Repairing at the read rather than at the toggle also covers
`sendDesktopNotification()`, which gates delivery on `=== "granted"` and
would otherwise drop notifications at boot.

`denied` stays terminal on macOS, on Linux and on ordinary Windows web
pages, and a denial that survives the request is still reported as
`denied`.

Subject: [PATCH 05/76] fix(desktop): show agent activity bar in DMs and
 threads

BUZZ-DESKTOP-003. Two related rendering gaps on the fork:

1. In DM channels the composer activity bar stayed empty even while
   observer frames arrived (sidebar working badge proved it).
   getChannelAgentSessionAgents filtered relay agents by the declared
   channel_ids of their kind:10100 profile, and DM channels never
   appear there, so every relay agent fell out of activityAgents in
   its own DM. For DMs the channel participantPubkeys are now the
   authoritative admission signal.

2. Thread panels fed threadComposerBotTypingPubkeys only from bot
   typing entries (kind 20002), never from the observer store, so
   threads rendered "is typing" at best. Merge the channel-level
   working set (observer-derived turns + typing) so threads show the
   same activity bar as the main composer. Observer frames carry
   channel scope only, which is the finest resolution available.

Both changes are additive desktop-only filters; relay and harness are
untouched. Unit tests: 4975/4975 pass (9 new), typecheck clean.

Subject: [PATCH 06/76] wip(desktop): deriveAgentSessions groups observer
 events by sessionId

Pure function building block for the planned Agent Sessions panel
(session tree grouped across agents). Not wired into any UI yet.

Subject: [PATCH 07/76] feat(desktop): agent sessions panel, DM context ring,
 metric data layer
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

BUZZ-DESKTOP-003 phase 1. Built on the notification-fix branch so the
next canary installer carries both.

- Agent Sessions panel behind preview flag agentSessions: sidebar
  button, /agent-sessions route, session tree (deriveAgentSessions,
  cherry-picked from Claude-Host WIP 9869cf8) + existing transcript
  components, per-session model/context%/cost header, stuck heuristic
  (open turn idle >15 min).
- DM context ring in the composer toolbar: fill = latest archived
  kind:44200 turn.inputTokens for the channel / model context window;
  color steps at 60%/85% to surface degradation before the window
  fills.
- Data layer reads decrypted kind:44200 payloads via the existing
  owner_p archive path — no Rust changes. modelContextLimits.json
  ships ~60 known windows (Claude/GPT/Alibaba token-plan Qwen/
  Gemini/DeepSeek/Llama/Mistral) with prefix matching and the
  200k->1M observed-max heuristic.
- Empirically verified 2026-08-20: Claude-Host/Claude-Review/Robi
  publish kind:44200; Claude-DEV had zero all-time (harness-side
  detection issue, fixed separately as BUZZ-ACP-017).

Tests: 5003/5003 unit (18 new), tsc clean, biome clean.

From 67d3f24794d83abb38cb0c4338d1c1b8aa8ce71d Mon Sep 17 00:00:00 2001
From: Robi Hermes <robi.cholewa@gmail.com>
Date: Fri, 21 Aug 2026 10:22:46 +0200
Subject: [PATCH 08/76] fix(desktop): restore membership-first mention
 authorization (cherry-pick bc519523)

The sessions-panel build (feat/agent-sessions-panel) branched from
fix/windows-notification-permissions, which predates the integration
branch carrying PR #5881 (membership-first mentions). The new canary
client therefore fell back to directory channel_ids-only eligibility:
agents added to a new channel were members but not mentionable.

Cherry-picks bc519523 (authorize external member mentions) onto the
sessions-panel branch: live channel membership now admits relay agents
into the mention picker even when their kind:10100 profile is stale;
response policy and allowlist remain enforced, send-boundary
revalidation still fails closed.

Regression 2026-08-21: Claude-Host added to 2 new channels -> member
in both, absent from @-mention picker until profile re-publish. Fix
removes the profile-dependency entirely (per LOCAL_MODIFICATIONS
BUZZ-DESKTOP-002).

Tests: 39/39 focused unit tests green, tsc --noEmit clean.

From ffed2a25029d17b5eac017320e204354ed617bfb Mon Sep 17 00:00:00 2001
From: Robi Hermes <robi.cholewa@gmail.com>
Date: Fri, 21 Aug 2026 10:42:59 +0200
Subject: [PATCH 09/76] feat(desktop): restore read-only 'On this relay' agents
 section (cherry-pick 8ca8852b)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Second half of the documented BUZZ-DESKTOP-002 contract
(LOCAL_MODIFICATIONS.md: patches/buzz-desktop-pr5883-pr5881.patch) was
missing from the sessions-panel branch — only #5881 (membership-first
mentions) had been restored. This cherry-picks upstream PR #5883 so
external kind:10100 relay agents are visible and inspectable again in
the Agents view.

Cherry-pick applied clean on feat/agent-sessions-panel.

Signed-off-by: Robi Hermes <robi.cholewa@gmail.com>

Subject: [PATCH 10/76] feat(desktop): Reset-session button in the Agent
 Sessions panel
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Kills stuck/dead ACP sessions from the sessions panel: publishes the
harness '!rotate' owner command (kind 9, content exactly '!rotate',
agent p-tag mention) into the session's channel. buzz-acp consumes it
owner-side — in-flight turns are cancelled and the channel session
invalidated; idle channel sessions are dropped immediately, so the next
mention starts a fresh session.

Motivation: session corpses (e.g. a crashed turn leaving a 'stuck?'
row in the tree) had no cleanup path from the UI; today only manual
CLI '!rotate' messages or a service restart clear them.

- RotateSessionButton in the session header, confirm dialog, toasts
- isRotateSessionAuthorized lib gate: enabled only for identities in
  the agent's respond-to allowlist (harness stays owner-authoritative
  either way); unlisted agents stay ungated, harness rejects non-owner
- 8 unit tests green, tsc clean

Subject: [PATCH 11/76] feat(cli): expose NIP-34 issue status events + repos
 delete tombstone
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

issues get/list now include status-transition events (kind 1630-1633)
with content, making `buzz issues status --content` readable — the
commentary was accepted by the relay but had no CLI read path.

repos delete removes one's own repo announcement via a head-based
kind:5 tombstone, mirroring projects delete (submit + re-query verify).

Subject: [PATCH 12/76] fix(cli): tombstone timestamps must respect relay drift
 window
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The relay rejects events whose created_at drifts more than ±15 minutes
from server time. Both projects delete and the new repos delete built
the tombstone at head.created_at+1, which fails for any head older than
~14 minutes. Use max(head+1, wall-clock) instead.

Subject: [PATCH 13/76] fix(desktop): make the media download cap symmetric
 with the upload cap

The Windows client refused any download above 50 MiB while the relay
accepts generic-file uploads up to 100 MiB (buzz-media
default_max_file_bytes). A 51 MiB installer uploaded cleanly and was then
undownloadable by the same client: "file too large (51 MiB, max 50 MiB)".

Raise MAX_DOWNLOAD_BYTES to 104_857_600 so the two caps match, and split
the clipboard decompression-bomb guard onto its own constant. That guard
bounds the decoded RGBA buffer rather than the transferred bytes, so it
must not grow just because the transfer cap did; it stays at 50 MiB.

Subject: [PATCH 14/76] feat(desktop): set issue status from the issue detail
 rail
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The desktop could read NIP-34 issue status but never write it: pull
requests have lifecycle buttons, issues had a static badge, and the only
way to move an issue was `buzz issues status` on the CLI.

The status badge in the issue meta rail becomes a picker that publishes a
status event (1630 Backlog / 1633 Triage / 1631 Done / 1632 Closed). The
event carries the repo coordinate in an `a` tag, which is load-bearing:
fetchProjectIssues reads status events with an `#a` filter, so an event
without it is invisible to the desktop and the issue silently falls back
to Backlog.

"In Progress" and "In Review" stay label heuristics with no status event
behind them, so they can be the current state but are never offered as a
choice.

The picker follows the same trust rule the parser applies
(allowedActorsForRoot): only the issue author and the repo owner. When the
repo owner is a managed agent, sign_project_issue_status signs on its
behalf — the mirror of sign_project_pull_request_status.

Also records statusCreatedAt on the parsed issue so a second change inside
the same whole-second Nostr timestamp still outranks the one it replaces.

Subject: [PATCH 15/76] fix(desktop): let issue assignees change issue status

The status picker and the status read path trusted only the issue author
and the repo owner. Handlers (assignees) who actually work a ticket could
not move it.

- canChangeProjectIssueStatus now accepts anyone assigned to the issue
- latestStatusForIssue honors status events published by assignees, so a
  handler's status change is not silently discarded on re-read
- eventToProjectIssue resolves assignment state before status so the
  assignee set is known when the status event is checked
- assignments keep their existing authority rules; strangers are still
  ignored

Subject: [PATCH 16/76] feat(desktop): reset and kill buttons on every agent
 session row
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Each session row in the Agent Sessions panel now carries two icon buttons:

- Reset (RotateCcw): sends !rotate to the session's channel, owner-gated
  exactly like the former transcript-header button, which this replaces
- Kill (Trash2): removes the session from the list on this device

Kill is a display-level removal — observer frames are immutable relay
data. Killed session ids persist per identity in localStorage; the agent
counter and empty state follow the visible set, and killing the selected
session clears the transcript view. Reset keeps its confirm dialog.

Subject: [PATCH 17/76] fix(desktop): accept JSON-degraded IPC bodies for raw
 media uploads

Drag-drop/paste uploads failed with 'raw upload requires a byte body' for
any file type (e.g. PDF). Tauri's webview IPC prefers a custom-protocol
fetch that carries raw bytes, but after a single failure of that transport
(e.g. AV/VPN interception of ipc.localhost) it permanently falls back to
postMessage, which JSON-serializes the byte payload into a number array.
The renderer sends the same call; only the transport changed.

upload_media_bytes_raw now recovers the bytes from that JSON number-array
shape instead of rejecting it, with strict validation (integers 0-255 only).
The raw fast path is untouched while it works. Adds unit tests covering
recovery, out-of-range numbers, negatives, and non-array bodies.

+//! Conversation scoping for buzz-acp.
+//!
+//! A **conversation** is the unit that owns an ACP session, a turn counter, a
+//! delivery ledger, a queue, and the mid-turn steer/cancel path. It is *not*
+//! the channel:
+//!
+//! - **DM channel** — exactly one conversation, replies included. A DM is
+//!   already a two-party thread; splitting it per NIP-10 root would fragment a
+//!   single human conversation across sessions.
+//! - **Group channel, top-level event** — the event's own id is the stable
+//!   conversation root.
+//! - **Group channel, reply** — the NIP-10 `root` event id is the stable
+//!   conversation root, so every reply under a root reuses that root's session.
+//!
+//! Two threads in the same group channel therefore never share an ACP session,
+//! turn counter, delivery ledger, cancelled batch, retry state, or in-flight
+//! control path.
+//!
+//! Membership removal and agent teardown stay channel-wide and iterate every
+//! conversation scope belonging to the channel. Owner `!cancel` / `!rotate`
+//! commands intentionally target only the conversation where they were posted.
+//! Channel metadata, canvas, and core-memory caches remain channel-keyed —
+//! those are properties of the channel, not of a thread.

Subject: [PATCH 20/76] feat(desktop): improve project issue workflow

- filter aggregate issues by repository and show full active groups
- prioritize review-ready workflow evidence over historic approval labels
- reset channel issue detail navigation and expose a visible back action
- place Channel Issues before Buzz Terminal in the channel header
- cover repository filtering, status precedence, navigation, and action order

Subject: [PATCH 24/76] feat(buzz-acp): answer list_models control frames with
 the model catalog

The desktop can already switch a running agent's model over the relay
(`switch_model`), but it can only learn which models exist from
`session_config_captured`, which is emitted on session creation. An agent
that has not run a turn since spawn therefore has no catalog on the
desktop side, and a picker fed only by that frame comes up empty.

Add a read-only `list_models` control frame that answers from the
catalog buzz-acp already caches on the agent, flattened across both ACP
dialects so the desktop sees one shape and every id it is offered is an
id the switch path can resolve. `providers` narrows the answer to given
provider prefixes.

The catalog is read process-wide rather than per channel, matching the
assumption `switch_idle_agent_model` already relies on when it validates
a pick against every worker. Statuses reuse that path's vocabulary
(`catalog_unavailable`, `no_active_turn`) so the desktop learns one set
for both frames.

The response caps its own list. This is not defensive padding: measured
against kilo 7.4.11, the model catalog is 698 entries / ~60 KB against a
65,535-byte observer budget, and the generic oversize path cannot help,
because it elides string leaves with a 3 KB retain floor while model ids
are 20-50 bytes. An oversized catalog is therefore not trimmed but
replaced wholesale by the "payload too large" stub. Truncating with an
explicit flag is the difference between a short list and no list.

No session is created and no agent state changes.

Subject: [PATCH 25/76] fix(buzz-acp): scope model switching to one
 conversation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

BUZZ-ACP-019 gave every thread in a group channel its own ACP session but
left `switch_model` keyed on the channel. Two defects followed.

First, blast radius. The idle path called `invalidate_channel`, which drops
the session, turn counter and delivery ledger of *every* conversation in the
channel. That was harmless while a channel had exactly one session; after
the split it means switching the model from one thread silently resets every
sibling thread's context. The switch now invalidates only the conversation
that asked for it. Siblings keep their sessions and pick the new model up
when their own session is next created.

Second, the busy path was removed. `ControlSignal::SwitchModel` and its
oneshot delivery were replaced by a fail-closed `in_flight_ambiguous`, which
fires whenever *any* turn in the channel is running — including the caller's
own. That disables the switch in exactly the situation it is meant for:
escaping a rate-limited provider mid-turn. The signal is restored and
delivered per conversation via `signal_in_flight_conversation`, so the turn
is cancelled, the model lands, and the batch is requeued under it. Refusal
is now narrowed to the case that genuinely cannot be made safe: a worker
checked out by some *other* conversation, which is unreachable from the pool
and would keep serving the old model.

The override stays agent-global by design — `desired_model` lives on the
worker process, not the conversation — so `set_model_on_held_slots` replaces
`switch_idle_agent_model`: it sets every held slot and leaves invalidation,
a policy decision, to the caller.

Also carries the conversation root on kind:44200 turn metrics. The payload
had `channelId` but no thread identity, so after the session split every
thread of a channel folds into one number and a per-thread context readout
is impossible. `threadRoot` is additive and omitted for DMs and heartbeats,
which have one conversation per channel anyway.

Tests: 840 buzz-acp + 9 lifecycle + 253 buzz-core, clippy --all-targets
-D warnings clean. The sibling-survival guard was verified to fail against
the previous `invalidate_channel` behaviour before being committed green.

+======
+
+MyBuzz issue-to-human-acceptance wire contract
+-------------------------------------------
+
+`draft` `optional` `P1 contract only`
+
+## Scope and compatibility
+
+This document and `NIP-BW.fixtures.json` specify inputs and expected projections
+for independent Host P2H and MyBuzz P2M implementations. Neither is an
+implementation, dispatch authorization, production policy, or deployment approval.
+MUST, MUST NOT and MAY are normative. All scopes include the host-derived community.
+
+Repositories remain NIP-34 kind **30617**; issue roots remain kind **1621**.
+Workflow records use **46100**, working constant `KIND_BUZZ_WORKFLOW_RECORD`.
+It is a regular, non-replaceable event, retained append-only by BW consumers.
+There is no `d` tag, replacement, latest-timestamp-wins, or deletion-as-undo.
+No production constant or kind registry is changed in P1.
+
+This advances VISION.md and VISION_SOVEREIGN.md: relay code and signed decisions
+remain authoritative; GitHub is a build mirror. Intentional tension with
+VISION_PROJECTS.md's standard-status interoperability: BW has stricter causal,
+assignment and human-verdict semantics than NIP-34 statuses can express. Standard
+clients can still discover issues and artifacts, but cannot authoritatively
+project BW progress. No new HTTP endpoint or legacy status mirror is introduced.
+
+## Registry and capability evidence (2026-09-09)
+
+Read-only checks of these official sources found no assignment of 46100:
+
+- [Nostr NIP index](https://github.com/nostr-protocol/nips/blob/master/README.md).
+- [Nostr kind registry](https://github.com/nostr-protocol/registry-of-kinds/blob/master/schema.yaml),
+  retrieved raw SHA-256 `88b471c3d567e1deea4b0365e32480e27e9f137fc1064d85bd4bc5536606044a`.
+- [Buzz kind constants](https://github.com/block/buzz/blob/main/crates/buzz-core/src/kind.rs),
+  retrieved raw SHA-256 `de54e283391b447fcf6a80c3c252debd3f9cadbb506abe899927fb8f2a748f96`.
+- Local `crates/buzz-core/src/kind.rs` at baseline
+  `83afea0a1549410a8f7effa12ceed0f7b13234e6`: workflow family 46000–46999,
+  existing execution kinds 46001–46012, trigger 46020, approvals 46030/46031;
+  46100 absent. Local docs/nips search also found no 46100 contract.
+
+[NIP-01](https://github.com/nostr-protocol/nips/blob/master/01.md) reserves the
+replaceable/ephemeral/addressable ranges below 40000; BW requires regular storage
+for 46100. Absence from these non-exhaustive registries is not a global reservation.
+Recheck before implementation; a future collision requires a contract revision.
+[NIP-34](https://github.com/nostr-protocol/nips/blob/master/34.md) and
+[NIP-94](https://github.com/nostr-protocol/nips/blob/master/94.md) retain their kinds.
+
+The Windows worktree's origin names the canonical Relay Git repository; its
+tracking remote is GitHub and MUST NOT be used as canonical evidence. The local
+Git read attempt failed because the configured helper had no Nostr key and Coder
+had no matching external-auth provider. No credentials were sought. No authorized
+Relay event-query session was available, so 46100 queryability and persistence
+are **unverified**. A later read uses explicit `kinds:[46100]` and repository `#a`
+filters, with pagination and referenced-ID fetches. An empty response, NIP-11
+metadata or source inspection does not prove storage. Persisting probes belong
+to P3. P1 does not publish any events or reactivate workflow triggers.
+
+## Bytes, primitive types and validation order
+
+An event has exactly the seven NIP-01 fields: `id,pubkey,created_at,kind,tags,content,sig`.
+No duplicate JSON keys at any depth; reject invalid UTF-8, lone surrogates, NaN,
+fractional/exponent-form numbers, negative numbers, BOM and trailing JSON data.
+Outer whitespace is permitted. Content is a JSON object for 46100, plain text
+for 1621/1/1063. Content field order and whitespace are signed bytes, not normalized.
+
+Event ID = SHA-256 of UTF-8 compact JSON
+`[0,pubkey,created_at,kind,tags,content]`, using NIP-01 escaping, no ASCII escaping
+of Unicode, and no newline. Preserve tag order and content string exactly.
+Verify BIP-340 `sig` over the 32 ID bytes using `pubkey`. Verify ID first, then
+signature; never treat a signature over an unrelated ID as valid.
+
+Limits are inclusive. IDs/pubkeys/digests are lowercase 64 hex characters;
+pubkeys must lift to valid secp256k1 x-only points. Signatures are 128 lowercase
+hex. Git object IDs are lowercase 40 hex (SHA-1 repository format in BW v1).
+Timestamps are integer Unix UTC seconds 0..4294967295, not milliseconds or strings.
+Other integers are 0..2147483647 unless specified. Text is measured in UTF-8 bytes.
+Total compact event JSON is at most 65536 bytes, content at most 32768 bytes,
+at most 16 tags, each tag string at most 2048 bytes (auth conditions at most 256).
+Human text uses `text` (1..2048 bytes), `longtext` (1..8192), `title` (1..256),
+or `note` (0..2048). URLs are absolute HTTPS without userinfo or fragment,
+1..2048 bytes; URLs are not credentials. Repository coordinates are
+`30617:<owner-pubkey>:<slug>`, slug `[a-z0-9][a-z0-9_-]{0,63}`.
+Stream is a single branch name `[a-z0-9][a-z0-9._/-]{0,127}`, additionally satisfying
+`git check-ref-format --branch`; no `..`, `@{`, trailing slash/dot or `.lock` component.
+Platform is `windows|android|ios|macos|acp`; client pipelines exclude `acp`.
+Release labels are `[a-z0-9][a-z0-9._+-]{0,63}` and unique per repository/pipeline.
+Arrays are ordered on the wire, unique by value unless a different key is stated.
+
+Processing stages, in this precedence, are: `envelope`, `id`, `signature`,
+`shape`, `attestation`, `references`, `policy`, `role`, `causality`, `external`,
+`projection`. First failing stage is returned. Within a stage choose the
+lexicographically smallest error code if multiple checks fail. Fixture codes are
+stable contract labels; a consumer may attach human details separately.
+
+Outcomes: `accept` (valid and projected), `reject` (permanent invalidity),
+`pending` (missing event/external evidence or future timestamp), `conflict`
+(multiple valid causal successors or competing resource claims), `replay`
+(already-seen identical ID, no second action), `ignore` (non-BW legacy event).
+Semantic expectations in fixtures are an oracle for P2, not executed by the P1
+structure checker. Decisions are relative to the complete supplied event set,
+external evidence and explicit `now`; replaying in another order converges.
+
+## Exact tags and machine schema
+
+`record` is exactly one two-string tag on every 46100 event. Its value selects
+one of the eleven record schemas below. Common required tags, each exactly once:
+`["record",type]`, `["a",repo]`, `["policy",policy-event-id]`.
+Genesis role-policy omits `policy` to avoid self-reference. Every other role-policy
+references its predecessor in `policy`. Other required tags by record:
+
+| Record | Additional required two-string tags | Optional two-string tags |
+|---|---|---|
+| role-policy | none | previous (absent only at genesis) |
+| issue-update | issue | previous (absent only for initial correction) |
+| triage-action | issue | previous, delegation |
+| issue-state | issue | previous (absent only for enrollment) |
+| issue-relation | issue | previous (absent only for first edge operation) |
+| release-pipeline | none | none |
+| release-set | none | previous (absent only at freeze) |
+| build-request | none | previous (absent only for first pipeline request) |
+| build-run | none | previous (absent only for first run snapshot per request) |
+| test-ready | none | previous (absent only for first handoff per set) |
+| member-verdict | issue | none |
+
+There are **eleven** 46100 record types. The separate NIP-94 artifact profile
+is specified below and checked explicitly by the validator. The machine schema
+list is authoritative for the 46100 enumeration. `issue` is the exact
+1621 root ID, never a comment or a repo announcement. `previous`, `policy`, and
+`delegation` are exact event IDs. No `e`, `h`, `p`, `d`, `t`, `expiration`, extra
+index hints or duplicated tags are allowed on 46100 records.
+
+All profiles additionally allow zero or one `auth` tag of exactly four strings
+`["auth",owner,conditions,signature]`, validated using [NIP-OA](NIP-OA.md).
+BW fails closed on invalid/duplicate attestations, stricter than OA's generic
+client ignore behavior. Keep the original tag in archival/export bytes. NIP-42,
+NIP-98, Git NIP-GS and relay membership are independent transport admission
+checks. A valid OA credential never changes `event.pubkey` or grants a BW role.
+The Host MUST additionally validate its configured roles before side effects;
+failure blocks execution even when the event's historical policy accepted it.
+
+`NIP-BW.fixtures.json.schemas` is the normative closed content-shape table.
+Each schema has `required` and `optional` maps. No other keys are allowed.
+Type names refer to the primitives above or closed named objects in `types`.
+`?T` permits JSON null; `[T]` is an array with bounds in `arrays`; `A|B` is an
+exact enum. An optional field is absent, not null, unless its type permits null.
+These closed schemas are shared contract data, not a general schema platform. Cross-field requirements
+below are normative and deliberately outside the P1 structural validator.
+
+## Causality and historical authority
+
+Each mutable object's genesis and `previous` successors form a directed chain.
+Chain keys are: repository policy; issue text; issue triage; issue state;
+`(issue,relation,target)`; frozen set lifecycle; pipeline requests; request run;
+set handoffs. Assignment uses its existing `prior` chain. Immutable pipelines,
+freeze payloads, artifacts and verdicts have no editable head.
+
+A reference must match repository, object, expected kind and record, and have
+`created_at <= successor.created_at <= now`. Missing references remain pending;
+invalid references reject dependents (`invalid-reference`). Cycles reject.
+A successor of an ancestor is not silently discarded as stale: if independently
+valid at that ancestor it creates a fork, even when delivered late. A descendant
+of another object is `wrong-previous`; a duplicate of a processed ID is replay.
+Two valid genesis or successors produce visible `fork` containing sorted event
+IDs. All descendants and dependent side effects are blocked, including previously
+projected descendants (display their history as disputed, never erase signatures).
+There is no automatic fork winner or in-band fork repair in BW v1. Owner must
+resolve operationally before adopting a separately reviewed protocol revision;
+clients must not fabricate a merge or bypass with a new timestamp.
+
+Validity is evaluated against the referenced historical parent snapshot, not
+arrival order. Changing a policy does not rewrite accepted history. A policy's
+`effective_at` must be >= its own created_at and strictly increase along the
+chain. At time t, use the last unconflicted policy with effective_at <= t.
+An event must reference that exact policy or reject `policy-binding`. A later
+policy arriving late may make a projection pending/disputed until its history
+is known. No signed timestamp proves real creation time; real-time side effects
+also require current external Host authorization and complete canonical readback.
+
+## role-policy
+
+Trust input is `(community,repo,owner-pubkey)` confirmed outside untrusted event
+content. Owner must equal the 30617 coordinate owner; announcement signature and
+coordinate must verify. Genesis is signed by that owner, version 1, no previous
+or policy tag. Successors are owner-signed with version increment exactly one,
+previous=policy=old policy. Owner rotation/new repository trust is outside v1.
+
+Content: version, effective_at, cutover, operators, coordinators, workers,
+human_testers and triage_delegations. Cutover is immutable after genesis and >=
+genesis effective_at. Role arrays contain 0..32 distinct pubkeys; human_testers
+contains 1..32. Workers maps each platform to 0..32 pubkeys; overlap is allowed.
+Operators provide Buzz-admin triage/classification powers, not Owner powers.
+Coordinators select delegates and manage release logistics. No hardcoded human
+or production keys. Display names such as Jari and Ania are not identity proofs.
+
+Each triage delegation is a closed object `{issue,action,delegate,expires_at}`;
+action is accept/duplicate/decline; at most 32 unique `(issue,action,delegate)`
+entries. A delegated triage event must tag `delegation` with that exact policy ID,
+match one entry, and be before expires_at. It authorizes one action at the issue's
+initial triage head only; another valid use is a conflicting successor, not an
+additional grant. Delegations do not authorize assignments, releases or verdicts.
+
+Only a consciously enrolled new issue participates: root created_at >= cutover,
+followed by reporter- or owner-signed issue-state `triage` referencing that root.
+Pre-cutover roots reject `cutover` even when updated later. Existing unmarked roots
+stay outside BW; old 1630..1633 and `mybuzz-status-v1` events are ignored, with no
+migration or status mapping. Enrollment never rewrites a root.
+
+## issue-update and triage-action
+
+Initial correction has no previous; all later corrections reference the prior
+issue-update. `patch` is a nonempty subset of title, description,
+acceptance_criteria, non_goals, type, priority, platform. Reporter, Owner,
+operators or coordinators may edit the first four text fields; only Owner,
+operators or coordinators may edit the last three. A mixed patch requires all
+field permissions. Criteria and non-goals are 0..25 unique text strings.
+Type is bug/feature/task; priority P0/P1/P2/P3. Initial values are root subject and
+content, empty criteria/non-goals, task/P2, platform null. Classification changes
+are allowed only in triage/backlog; text edits only before in-development.
+
+Triage content always includes action. Conditional fields are exact:
+accept: none; need-info: question and recipient; snooze: until;
+duplicate: target; decline: reason. Forbid all other conditional fields.
+All require an enrolled issue still in triage. Owner may perform any action;
+operators may need-info/snooze; accept/duplicate/decline additionally accept the
+single-task delegate above. Reporter status alone grants no triage power.
+Need-info question is nonempty and recipient is a pubkey. Duplicate target is a
+different same-repo 1621 root and adds projected duplicate-of relation.
+Decline reason is nonempty. Snooze until is > created_at and <= created_at+2592000.
+
+Accept projects backlog; need-info/snooze retain triage; duplicate/decline project
+closed. Issue-state backlog must reference the exact accepting triage event.
+Snoozed is a view at `now < until`, with no synthetic timer event. Stale is
+`now >= last_valid_activity + 604800`; valid activity is root enrollment,
+issue-update, triage-action, issue-state, assignment selection or member-verdict.
+Comments, invalid events, OA tags and replays do not reset stale time.
+
+## issue-state and the existing assignment wire
+
+Enrollment content: `{state:"triage"}`. Backlog: state plus `triage` ID.
+Ready: state plus `stream`, `assignment` (ID or null), `update` (latest text ID),
+and `rework` (rejected verdict ID or null). In-development: state, stream,
+assignment (non-null). Implemented adds commit, tests and remote_readback.
+No fields from another state are permitted. All post-enrollment records require
+previous = issue-state head. Transition sequence is triage → backlog → ready →
+in-development → implemented. Owner/coordinator may reset ready from ready,
+in-development or implemented, but implemented reset requires rejected verdict
+or a terminal failed/aborted set (the latter referenced in optional `terminal_set`).
+Resolved issues cannot reset. Ready needs nonempty acceptance criteria, classified
+platform, exactly one stream, and a current text snapshot; ACP work may be ready
+and implemented but is not client-release eligible.
+
+Existing local SDK grammar (`crates/buzz-sdk/src/builders.rs`,
+`build_git_issue_assignment_with_prior` / `build_git_issue_unassignment_with_prior`):
+kind 1, content <=65536 bytes, `e` = `["e",issue,"","root"]`, `a` = `["a",repo]`,
+1..50 distinct sorted lowercase `p` pubkeys, `t` = assignment or unassignment,
+optional `["prior",event-id]`. SDK normalizes/deduplicates supplied assignees;
+old consumers trust reporter/owner or sole self-assignment/unassignment.
+These are existing semantics, not BW authorization.
+
+BW consumes that same signed operation format (optional OA retained), with the
+stricter common 32768-byte content/65536-byte event limit, at most one p tag,
+and no other tags. First assignment omits prior; every subsequent operation must
+reference the unique prior operation. Assignment adds the sole delegate only
+when none exists; unassignment removes exactly the current delegate. Only Owner
+or the coordinator active at operation.created_at may sign BW operations.
+There is no new record kind, self-assignment shortcut or inherited OA authority.
+Operations themselves do not change the active writer: Owner/coordinator must
+select the exact operation head in a ready event. Ready with assignment null
+requires an empty assignment fold. A non-null selection must equal the final
+assignment head and contain exactly one delegate. Changes after selection suspend
+writer actions until reselection; a fork blocks selection and all writer actions.
+
+Only that delegate signs in-development and its implemented successor, with the
+same stream and assignment head. Switching delegate requires unassignment,
+assignment, and Owner/coordinator ready reset. Earlier valid work stays historical;
+late old-writer work is rejected `assignment-head` when its claimed current
+assignment was superseded at its created_at. Backdating cannot authorize Host
+execution: external current selection is an additional mandatory check.
+
+Implemented `remote_readback` is `{repo,stream,head,observed_at}`. Head must equal
+commit and externally observed canonical Relay head, observed_at <= created_at,
+with age <=300 seconds. Tests is a nonempty summary, including honest limitations.
+The signed claim alone proves no remote fact. Implemented means source work and
+remote readback only, never a build, installation test or human acceptance.
+
+## issue-relation
+
+Content `{relation,target,operation}`; relation blocks/related/duplicate-of/parent-of,
+operation add/remove. Owner/coordinator only; both roots enrolled in the same repo;
+no self-edge. First op must add; subsequent ops alternate remove/add via previous.
+Inverse views: blocks↔blocked-by, related↔related (canonical endpoint order is
+lexicographically ascending root ID), duplicate-of↔duplicates,
+parent-of↔child-of. Inverse views are not extra events. Triage duplicates also
+contribute an immutable duplicate edge; explicit remove cannot remove that edge.
+Reject parent or blocking cycles. An executable leaf is a non-closed, non-resolved
+issue with no active child, no duplicate-of edge and no unresolved blocker.
+Conflicted relation history blocks eligibility. Active-set members cannot acquire
+children, duplicate edges or blocking edges until the set terminates.
+
+## release-pipeline and release-set
+
+Pipeline ID is its immutable event ID, Owner-signed. Content binds platform,
+stream, workflow path, workflow_sha256, manifest_schema, manifest_sha256, mirror URL,
+runner identity, publisher pubkey and provider. Policy tag pins allowed workers and
+roles. Path is 1..256 characters, relative POSIX, no empty/dot/dot-dot components.
+Manifest schema is a nonempty versioned contract name. Any change, including
+role-policy binding, requires a new pipeline event ID; no mutation of existing sets.
+Platform excludes ACP. Publisher must be a worker for this platform in that policy.
+
+Freeze content has action=freeze, release, pipeline, platform, stream, relay_sha,
+members, readback. Set ID is freeze event ID. Owner/coordinator under the pipeline's
+pinned policy signs it; its policy tag must equal that policy (exception to current
+policy selection for the complete pipeline/set lifecycle). Host current-role check
+still applies. Every downstream release event uses that pinned policy.
+Readback has the remote_readback shape with head=relay_sha and age <=300 seconds.
+Member is `{issue,implemented}`; 1..25 distinct issue IDs and implemented IDs,
+all same repo/platform/stream, exact current implemented state, executable leaves.
+External Git input must show every implemented commit is an ancestor of relay_sha
+(including equality), and freeze readback must be the actual Relay stream head at
+freeze. A signed claim or a GitHub ref is insufficient.
+
+Only freeze creates a set. `release-set` may later close it with content
+`{action:"close",set:freeze-id,outcome:"failed"|"aborted",reason}` and previous
+= lifecycle head (initially freeze). Frozen fields are never repeated or replaced.
+No close while an external provider run remains nonterminal; cancellation must
+first be read back. Completed sets need no close: after verdicts for all members,
+the set is completed even with partial rejection. A closed/completed set never
+reactivates. Failed run alone yields retryable active set, not terminal failed set.
+Active = frozen/requested/building/retryable/test-ready/partially-reviewed.
+Terminal = completed/failed/aborted. Active membership excludes other active sets.
+Two concurrent valid freezes sharing a member conflict and block both; no ID or
+timestamp tie-break. Closing one disputed claim is not an implicit conflict repair.
+
+Terminal status releases membership for new freezes. Accepted issues remain
+resolved forever in v1 and cannot be members again. Rejected issues enter rework;
+ready reset requires that verdict, a new delegate cycle if needed, and new
+in-development/implemented events. Failed/aborted sets allow reuse of an unchanged
+implemented event, or explicit ready reset referencing terminal_set. This avoids
+membership deadlock without mutating frozen membership or inheriting verdicts.
+
+## build-request and build-run
+
+Set existence dispatches nothing. Owner/coordinator signs explicit build-request
+`{set,worker,attempt,retry_of}`. Worker is exactly one platform worker in pinned
+policy, attempt starts at 1, retry_of is null. Subsequent attempts increment by one
+and reference the prior terminal failed/cancelled run ID. A successful run cannot
+retry; a new handoff may refer to it, or a new set/pipeline is needed for rebuilding.
+
+Requests form one previous chain per pipeline, even across sets, establishing an
+exclusive building lock. A next request requires its predecessor's final run and
+any associated handoff to be settled; different sets may build once previous run
+is terminal (human testing need not finish). Retry of the same set additionally
+requires failed/cancelled predecessor run. At most one Building set per pipeline.
+Concurrent children conflict and block dispatch, even if one was first observed.
+Same `(pipeline,set,attempt)` with different IDs conflicts; identical event replay
+never dispatches again. Durable dispatch idempotency key is request event ID.
+Worker reconciles that key with provider before any retried API call; uncertain
+provider outcome remains pending and holds lock. New attempt is never a transport
+retry substitute. Offline event history alone cannot provide distributed locking;
+P2H must serialize side effects after canonical readback and reconcile provider.
+
+Run content: request, provider, run_id, attempt, url, head, result, observed_at.
+Run ID is 1..128 ASCII `[A-Za-z0-9._:-]+`; result queued/running/success/failure/cancelled.
+Request worker alone signs; provider equals pipeline.provider; attempt=request.attempt;
+head=set.relay_sha. First snapshot may be any result; subsequent snapshots preserve
+all identity fields and progress queued→running→terminal or queued→terminal.
+Terminal has no successor. Every snapshot requires external provider readback keyed
+by provider/run_id, including request idempotency key, URL, attempt, head and result,
+with observed_at <= created_at and age <=300 seconds. Wrong facts reject; unavailable
+facts remain pending. Never trust arbitrary run URLs or signed success claims alone.
+
+## NIP-94 artifact and test-ready
+
+Kind 1063 uses plain-text description (1..2048 bytes). Exact required singleton
+arity-2 tags: a, set, run, platform, release, url, m, x, size; optional auth only.
+There is no record or policy tag: policy is inherited via set. `set` and `run`
+are exact IDs, `release` equals set label, `platform` matches pipeline, `x` is
+SHA-256, `size` is canonical unsigned decimal 1..2147483647. MIME is lowercase
+`type/subtype` (ASCII tokens `[a-z0-9.+-]+`). Publisher alone signs. Run must be
+successful for the exact set; external downloaded raw bytes must match size and x.
+No archive unpacking, decompression, Unicode or newline normalization before hash.
+
+Test-ready content: set, run, artifacts (1..8 distinct 1063 IDs), installation,
+limitations, tester. Request worker signs; all artifacts reference same set/run and
+are published by pipeline.publisher. Tester is exactly one pinned-policy human.
+Windows pilot requires installation.method=`tailnet-download`, unsigned=true,
+immutable=true, installation.url equal an artifact URL, and external publisher
+readback attesting immutable Tailnet availability. Other platforms use method
+`download` with immutable=true. `instructions` is nonempty. Limitations is nonempty,
+and Windows must explicitly state unsigned status in human-readable text.
+Ephemeral CI artifact URLs alone fail `durability` even if hashes match.
+
+Handoffs form a previous chain per set. A later handoff requires all verdict slots
+of the old handoff still empty; after any valid verdict a new handoff in that set
+is forbidden (`handoff-locked`). Before verdicts, a new handoff may select another
+allowed human or corrected artifacts, but old handoff verdicts reject `old-handoff`.
+New artifacts never inherit any verdict, even when their bytes happen to match.
+
+## member-verdict
+
+Content: set, test_ready, artifact, verdict (accepted/rejected), reason (nonempty).
+Issue tag must name a member. Artifact must belong to current test-ready and the
+exact set; tester signer must equal that handoff's chosen pinned-policy human.
+Either authorized Jari or Ania is enough when selected: no quorum and no name
+matching. Slot key `(set,test-ready,issue)` allows one immutable verdict. A second
+valid differing event for the slot produces `verdict-conflict` and blocks derived
+resolution for that issue (even two accepts); exact event replay is idempotent.
+There is no verdict overwrite. Human correction requires separately reviewed
+conflict resolution outside v1, not another timestamp.
+
+Accepted resolves only this issue, rejected projects only this issue to rework.
+Accepted siblings stay resolved across sibling rejection and subsequent rework.
+Accept all means N individually signed events, never a batch wildcard verdict.
+Wrong member, foreign set/artifact, old handoff, terminal aborted/failed set or
+new-set artifact with old verdict all reject. Completed-set existing verdicts
+remain authoritative; no new slots or replacements may be added afterward.
+A new set after rework requires a new handoff and fresh individual verdicts.
+
+## Corpus and P1 validation
+
+The corpus is standalone deterministic JSON. `events` contains complete signed
+Nostr inputs, including deliberately malformed cases; labels are fixture-local,
+never wire aliases. `cases` lists ordered event labels and per-step expected
+outcome/stage/code plus exact partial projection assertions (unspecified projection
+keys are unconstrained). Each case starts from empty event history and its explicit
+trust/external inputs. `now` is explicit. `base` is not supported: prerequisites
+are listed in full. `crypto` labels distinguish invalid-ID/signature cases from
+semantic cases. Each event carries expected cryptographic results in metadata;
+semantic negatives are signed correctly so they reach the intended stage.
+
+External inputs are named `git_readbacks`, `git_ancestry`, `provider_readbacks`,
+`downloads` and `host_authorization`. They are test-oracle observations, never
+inferred from signed claims. Downloads include exact raw bytes as lowercase hex
+and explicit durability facts. Fictitious pubkeys derive only from public test
+scalars 1..9, using BIP-340 reference code, zero auxiliary randomness. They MUST
+NEVER be funded, deployed or treated as production identities.
+
+Run `python3 scripts/check-nip-bw-fixtures.py` and
+`python3 scripts/test-nip-bw-fixtures.py`. These check JSON/schema/corpus structure,
+ID preimages, references within the corpus, required coverage and checker rejection
+of damaged corpora. They do **not** implement BW roles/folds. Optional Schnorr checking uses the
+public [BIP-340 reference](https://github.com/bitcoin/bips/blob/master/bip-0340/reference.py):
+download that file outside the repository, then pass
+`--bip340-reference /path/to/reference.py` to the checker. It pins the reference
+SHA-256 from corpus provenance before loading it, and checks every declared
+signature expectation. This proves cryptographic vectors only, not BW semantics. Host and MyBuzz must later execute all semantic expectations themselves.
+No build, service, relay probe, product parser or human acceptance test is implied.
+
+Hash final file raw bytes with `sha256sum docs/nips/NIP-BW.fixtures.json
+ docs/nips/NIP-BW.md`. Digests and exact commit belong in the handoff report,
+not either hashed document; no circular/self-referential digest. Any byte change
+invalidates its digest and independent review binding. P2 opens only after final
+technical checks, exact canonical remote readback and independent PASS at that
+commit and fixture digest. Source push with REVIEW AUSSTEHEND does not open P2.

+Handoffs form a previous chain per set. Evaluate supersession against the complete
+known history, never arrival order: an otherwise valid verdict on the old handoff
+with created_at <= the proposed successor's created_at prevents that successor
+(`handoff-locked`). Equal timestamps keep the verdict and the existing handoff;
+this is a cutoff rule, not selection between competing handoff heads. If no such
+verdict exists, the successor may select another allowed human or corrected
+artifacts. A verdict referring to the old handoff with created_at strictly after
+that valid successor rejects `old-handoff`. Recompute both records if one arrives
+late: retract the invalid derived projection and expose the reason while retaining
+both signed events. A fork of otherwise valid handoff successors remains conflict,
+not a timestamp winner. A conflicted verdict slot also prevents supersession.
 New artifacts never inherit any verdict, even when their bytes happen to match.
+As with policy cutoffs, timestamps do not prove real-world chronology; Host current
+canonical readback and role checks still gate any side effects.

+Handoffs form a previous chain per set. A successor selects the current handoff
+for operational display and future coordination; it does **not** revoke any prior
+handoff's exact artifact/tester binding. Historical handoffs remain reviewable.
+There is no verdict-time cutoff, `old-handoff` rejection or `handoff-locked` rule.
+A handoff can follow a verdict or a completed set, provided it references a verified
+successful run and fully verified artifacts. It never reopens the set or issue.
+Two otherwise valid successors still produce a visible `fork` and block operational
+selection; do not choose a timestamp winner. Each exact historical branch can
+still carry a valid human review. New artifacts start without verdicts, even when
+their bytes match an earlier artifact. A resolved issue does not imply that a new
+artifact has been accepted.
+
+## member-verdict and deterministic acceptance
 
 Content: set, test_ready, artifact, verdict (accepted/rejected), reason (nonempty).
-Issue tag must name a member. Artifact must belong to current test-ready and the
-exact set; tester signer must equal that handoff's chosen pinned-policy human.
-Either authorized Jari or Ania is enough when selected: no quorum and no name
-matching. Slot key `(set,test-ready,issue)` allows one immutable verdict. A second
-valid differing event for the slot produces `verdict-conflict` and blocks derived
-resolution for that issue (even two accepts); exact event replay is idempotent.
-There is no verdict overwrite. Human correction requires separately reviewed
-conflict resolution outside v1, not another timestamp.
-
-Accepted resolves only this issue, rejected projects only this issue to rework.
-Accepted siblings stay resolved across sibling rejection and subsequent rework.
-Accept all means N individually signed events, never a batch wildcard verdict.
-Wrong member, foreign set/artifact, old handoff, terminal aborted/failed set or
-new-set artifact with old verdict all reject. Completed-set existing verdicts
-remain authoritative; no new slots or replacements may be added afterward.
-A new set after rework requires a new handoff and fresh individual verdicts.
+The issue must be an exact member of the referenced frozen set. The artifact must
+belong to the **referenced** handoff and its exact successful run/set; the signer
+must be that handoff's selected human in the pinned policy. Do not substitute the
+currently displayed handoff, tester, run, artifact or policy. Either authorized
+Jari or Ania is enough when selected: no quorum and no display-name authorization.
+
+A valid historical verdict requires the complete exact reference closure: anchored
+repository and signed policy ancestry, enrolled issue and implemented/assignment
+history, frozen pipeline/set/member binding, request and successful run, artifact,
+handoff and selected tester. Check every event's shape, ID, signature, optional OA,
+roles, reference types/repository, causal ordering and required external evidence.
+Validate each referenced chain along its explicit previous/prior path at the
+relevant historical time, including policy version/effective-time rules. Competing
+valid branches and later operational head changes do not erase that branch's
+human-review evidence; this is the narrow exception to blocking operational
+projections on forks. No exception permits a forged signature, unauthorized signer,
+wrong repository/member/artifact, invalid chain edge, false Git/provider/download
+fact or missing proof. Such a verdict is rejected or pending and contributes
+nothing. A raw signed claim, prior local `accept` result or remembered UI state
+is never a substitute for replaying and verifying this closure.
+
+For a fixed trust context and verified external facts, let V(i) contain all valid
+historical verdicts for issue i in the supplied event history. Recompute from that
+history on every replay; no arrival-order winner, clock-based finalization, cache
+latch or new infrastructure is needed:
+
+1. If any v in V(i) says `accepted`, the issue is `resolved`.
+2. Otherwise, a valid `rejected` verdict puts that issue in rework until a valid
+   ready → in-development → implemented rework chain supersedes that rejection.
+3. With no valid verdict, use the ordinary workflow projection. A technical
+   conflict alone never produces `rework`, `rejected` or `resolved`.
+
+An accepted verdict cannot be superseded by rework. Adding handoffs, valid tests,
+builds, close records, valid competing branches or sibling verdicts cannot remove
+it from V(i). Missing historical dependencies may delay verification; when they
+arrive, recomputation must give the same result as receiving them first. Invalid
+proofs never qualify, even if previously asserted valid by a buggy client; this
+rule is not a promise to preserve a forgery or to ignore corrected external facts.
+
+Slot `(set,test-ready,issue)` is immutable. Two distinct valid event IDs for the
+slot produce `verdict-conflict` with sorted IDs, even if both say accepted; exact
+replay is idempotent. Keep all independently verified verdicts for the fold above:
+an acceptance still resolves the issue. A real signed rejection is evidence of
+a rejection, but cannot undo any valid acceptance. Technical conflict flags never
+stand in for a human's rejected verdict. No overwrite or invented human decision
+is permitted. Reviews in different handoffs are independent evidence for their
+own artifacts, not replacements of earlier evidence.
+
+Acceptance resolves only its own issue. Accepted siblings remain resolved during
+partial rejection, rework and new releases. Accept all means N individually signed
+verdicts. Completed, failed or aborted set status does not invalidate a fully bound
+historical review; set completion counts verdicts for that set only. Later verdicts
+may add artifact feedback or conflict flags but never clear prior member coverage.
+A new set after rework needs a new handoff and fresh artifact verdicts.
+
+Later defects in accepted work MUST be reported as a new 1621 issue root. Feature
+changes MUST use a new root classified `feature`, describing the concrete delta
+and its own acceptance criteria through the existing issue-update fields. A `related`
+edge may connect the new root to its accepted predecessor; it grants no authority
+to reset the predecessor. No new kind, follow-up schema, legacy status mutation
+or automatic reopening is introduced.
+
+Fixture projection `issues` maps real root IDs to workflow states; `conflicts`
+contains sorted real conflicting event IDs independently of issue state. The
+optional `artifact_verdicts[artifact-id][issue-id]` assertion is `unreviewed` with
+no valid verdict for those exact IDs, `accepted` or `rejected` with that sole
+value, and `conflict` when both values occur. This artifact feedback is not the
+issue-resolution fold. `issue_fields[issue-id]` asserts ordinary projected fields
+of that issue (for example a follow-up's type and concrete description).

+# NIP-BW P2M source handoff
+
+This is implementation evidence, not a revision of NIP-BW and not an activation
+or deployment authorization. Core has no I/O, wall clock or dispatch. SDK drafts
+are unsigned. `buzz bw` runs before the CLI's relay/key setup. Productive BW
+publication returns an error unconditionally; there is no activation flag.
+The activation prerequisite remains complete P3C readback.
+
+## Contract binding
+
+- P1: `529136c39aa42db64af61f811fc33dac73d16dd1`
+- Fixture SHA-256: `b489fb188b45e073e81783e8d591f24891a9c73bc56d8d2fc56a881606640e8a`
+- Document SHA-256: `832f80c7a8b1a3119952441988369af1d53cdc1ae4c4e761ff853e68681159c3`
+- Host counterpart supplied by Jari: `b5efd8ec4368e99d8117e29d77dcd8ce05d7ebcc`.
+  Its independent PASS and Relay readback are supplied evidence. Its full suite
+  reportedly has 561 passes and 35 pre-existing failures. No Host code is read or
+  changed by this implementation. The cross-implementation export comparison is
+  still a separate handoff, not a claimed joint P2 PASS.
+
+The compiled closed `bw/schema.json` contains only the unchanged `schemas`,
+`types` and `arrays` from P1. Tests compare those tables byte-semantically and pin
+both P1 file digests. No fixture event, test expectation or alias is compiled into
+the consumer. Test-only inputs use the existing public fictitious test keys.
+
+## Public namespace recheck: 2026-09-09 UTC
+
+A fresh read of the official [NIP index](https://github.com/nostr-protocol/nips/blob/master/README.md),
+[kind registry](https://github.com/nostr-protocol/registry-of-kinds/blob/master/schema.yaml)
+and [Buzz constants](https://github.com/block/buzz/blob/main/crates/buzz-core/src/kind.rs)
+found no assignment of 46100. This is not a global reservation. Local source adds
+`KIND_BUZZ_WORKFLOW_RECORD` to the workflow family and the duplicate-detection
+inventory; it remains a regular event and is not an engine command/trigger.
+
+## Offline API and commands
+
+`buzz_core::bw::Consumer::new(Trust, Evidence, now)` starts a fresh history.
+`ingest(raw_utf8_bytes)` returns actual `event_id`, `outcome`, `stage`, `code` and
+`projection`. `observe(evidence, now)` replaces observations; `projection()` then
+recomputes from the entire supplied history. `archived_inputs()` retains original
+input bytes, including rejected inputs. A rejected signature cannot poison an ID
+for a later genuine event. This API accepts no implicit key or transport.
+
+A validation file contains:
+
+```json
+{
+  "now": 1800001000,
+  "trust": {"community": "https://relay.example.invalid", "repo": "30617:<owner>:<slug>", "owner": "<pubkey>"},
+  "external": {
+    "git_readbacks": [], "git_ancestry": [], "provider_readbacks": [],
+    "downloads": [], "host_authorization": {"allowed": false, "current_policy": "<id>"}
+  },
+  "events": []
+}
+```
+
+Events are full signed objects or strings containing original raw event JSON.
+String inputs also allow an offline caller to inspect malformed wire JSON without
+losing lexical information in a containing document. External observations are
+trusted caller inputs, never values inferred from an event's signed claims.
+
+```sh
+buzz bw validate --input history.json
+buzz bw show --input history.json
+buzz bw dry-run --input unsigned-draft.json
+buzz bw corpus --input docs/nips/NIP-BW.fixtures.json --output p2m-results.json
+buzz bw publish  # always fails: full P3C readback required
+```
+
+Dry-run input has only `kind`, `tags`, `content`. SDK `bw::record(RecordType, tags,
+content)` inserts the typed discriminator and checks the same closed shapes.
+`bw::Draft::new` also supports the separate artifact, root and existing assignment
+profiles. It does not sign or return a transport. Existing standard SDK builders
+retain their existing behavior. `verify_readback` is pure: all seven signed fields
+must match and both ID and signature must verify. A private test transport checks
+acceptance, missing readback, mismatched readback and transport rejection.
+
+`bw corpus` verifies the fixture digest and executes every case from empty history
+with its explicit trust/evidence/time, without consulting `expected` or `crypto`.
+It exports computed results in corpus case/step order. JSON object maps and ID
+sets are sorted. The Rust corpus test separately checks all six outcomes, stages,
+codes and every specified partial projection, including `artifact_verdicts` and
+`issue_fields`. Unspecified projection keys remain outside the P1 comparison.
+
+Projection maps preserve issue acceptance separately from concrete artifact
+feedback and technical conflicts. `sets`/`handoffs` are keyed by real freeze IDs;
+`set`/`handoff` provide the latest authored set's display summary, without resolving
+competing claims. `dispatch_count` is an offline count of eligible unique requests,
+not evidence of a dispatch. There is no actual dispatcher. Host authorization is
+reported separately and cannot create a historical BW role or human acceptance.
+
+## Validation commands
+
+Use the repository's activated Hermit toolchain. Normal debug/test compilation is
+required; no release build, installation, deployment or live BW event is involved.
+
+```sh
+python3 scripts/check-nip-bw-fixtures.py --bip340-reference /tmp/nip-bw-bip340-reference.py
+python3 scripts/test-nip-bw-fixtures.py
+BW_RESULT_EXPORT=/tmp/p2m-results.json cargo test -p buzz-core
+cargo test -p buzz-sdk
+cargo test -p buzz-cli
+cargo fmt --all -- --check
+cargo clippy -p buzz-core -p buzz-sdk -p buzz-cli --all-targets -- -D warnings
+```
+
+The Python checks are structural/cryptographic checks only. The Rust corpus test
+executes 98 cases / 1,804 steps. Additional tests cover reversed delivery of every
+case, malformed lexical JSON, independent negative inputs, evidence correction,
+forged/genuine same-ID order, historical branches and the shared query matcher.
+Final command results and exact source/Remote SHA belong in the delivery receipt.
+Live persistence, live pagination and installed-consumer equivalence remain P3
+proof obligations. P2M does not reopen P1, begin P3 or grant product acceptance.
+
+## Relay capability evidence
+
+The local test `handlers::ingest::tests::bw_records_reach_regular_storage`
+executed the existing `required_scope_for_kind` predicate with signed P1 records.
+Before the change it failed with both
+`(46100, Err("restricted: unknown event kind"))` and
+`(1063, Err("restricted: unknown event kind"))`. Ingest returns that error before
+storage. This is a reproduced source capability gap, not a live Relay probe.
+
+The focused correction admits the two regular kinds with `MessagesWrite` scope
+and classifies their repository profiles as channel-less. Normal authentication,
+community fences and event verification remain in the ingest path. The existing
+regular-event branch calls `insert_event_with_thread_metadata`; neither kind is
+replaceable/addressable, ephemeral or an execution command. No BW trigger,
+legacy review action or consumer-role bypass is added.
+
+REQ source is unchanged. Explicit kinds avoid the global kindless p-gate; IDs,
+time bounds and limit are pushed into `EventQuery`. `#a` uses the existing
+NIP-01 result matcher. Core tests execute that same matcher for 46100 and 1063
+with kind/repository/ID/time filters and reject a foreign repository or an earlier
+page bound. These tests prove classification and filter behavior, not database
+persistence. In particular, generic-tag filtering occurs after the bounded SQL
+candidate page: live repository pagination/completeness must be checked in P3.
+No empty response or this source inspection is presented as a persistence proof.
+
+Because ingest source changed, the complete `cargo test -p buzz-relay` suite and
+relay Clippy lane are also required. Environment-dependent failures, if any, are
+reported individually in the final receipt rather than relabeled as PASS.
+
+The pre-commit complete Relay run produced 874 passes, 43 ignored tests and these
+8 failures. The new BW regression passed. No attempt was made to start services
+or rewrite unrelated tests to make this suite green:
+
+- `api::admin::tests::feedback_attachment_rejects_unknown_feedback`: 500 instead of 404.
+- `api::admin::tests::report_detail_rejects_unknown_report`: 500 instead of 404.
+- `api::media::tests::media_read_accepts_range_header_only_after_auth`: `Sqlx(PoolTimedOut)`.
+- `api::media::tests::media_read_rejects_upload_verb_wrong_server_and_wrong_x`: `Sqlx(PoolTimedOut)`.
+- `api::media::tests::media_read_with_valid_server_scoped_token_reaches_sidecar_gate`: `Sqlx(PoolTimedOut)`.
+- `api::media::tests::media_reads_reject_unauthenticated_get_and_head_before_sidecar_gate`: `Sqlx(PoolTimedOut)`.
+- `api::media::tests::upload_concurrency_limit_is_scoped_by_community`: `Sqlx(PoolTimedOut)`.
+- `api::media::tests::upload_rate_limiter_is_scoped_by_community`: `Sqlx(PoolTimedOut)`.
+
+The Admin tests also use a lazy Postgres pool; their 500s are consistent with the
+unavailable database, but are reported as observed failures, not a demonstrated
+baseline PASS. These remain open package/integration evidence. The final run uses
+`--no-fail-fast` so that failures in the Relay test binary do not suppress the
+other package targets or doc tests.

Subject: [PATCH 46/76] feat(bw): gate publication on activation and exact
 readback
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Publication was refused unconditionally, so no authorized operation could
reach the relay even with a signed genesis and a confirmed readback. Replace
the flat gate with a narrow producer that proves its own preconditions.

Activation is resolved from externally confirmed trust plus the signed
history: an owner-signed repository genesis matching the confirmed
coordinate, and exactly one role policy in force. A foreign owner, an absent
genesis, a not-yet-effective policy and competing policy heads each refuse.
No flag, environment variable or asserted event ID can stand in for it.

Operations are validated before signing. An unsigned candidate decodes into
the same record form signed events use, which pins the NIP-01 ID the
signature will carry, and is then evaluated by the existing offline
consumer in a copy of the history — same roles, references, causality and
external facts, no second trust engine and no local latch. Because the ID is
pinned before signing, an unclear delivery is resolved by re-reading that one
ID; a retry can never generate a second transition. Success requires a
readback that is byte-exact against the sealed event and still valid
semantically, and only then does the event enter the local history.

The offline subcommands keep working with no relay, key or network, and
refusals carry only the closed bw:<outcome>:<stage>:<code> vocabulary —
no projection, content or key material.

Productive use stays out of scope here: the CLI performs no I/O and the live
transport implementation is deliberately absent.

From babcf7d3219d8fefebfb54524e6e11e4017559cd Mon Sep 17 00:00:00 2001
From: Robi Hermes <robi.cholewa@gmail.com>
Date: Thu, 10 Sep 2026 16:17:02 +0000
Subject: [PATCH 47/76] feat(desktop): read the shared BW projection into
 project issues (P4C)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Desktop issue views (list, grid, detail) now read BW-enrolled issue
state through a single bridge to the already-tested Core NIP-BW
consumer, instead of only the legacy 1621/1630-1633 status events.

- crates/buzz-core: expose Consumer::inspect_all() so a caller can
  re-check every archived input against the fully-converged history in
  one pass (used by the desktop snapshot, not a second BW engine).
- desktop/src-tauri: new bw_projection bridge (bw_projection.rs) and
  Tauri command (commands/project_bw.rs, get_project_bw) that page
  repo-scoped events from the relay, fetch referenced IDs on demand
  (including foreign-repo bindings so Core can reject them), preserve
  original event bytes, and hand Core an explicit Trust/Evidence/now
  snapshot — no external evidence is ever inferred from a signed claim
  (host_authorization stays {"allowed": false}, all evidence arrays
  empty) until a later phase actually collects it.
- desktop/src/features/projects: bwProjection.ts merges the Core
  projection into the existing ProjectIssue shape for list/detail/next
  actor. A BW-enrolled issue's legacy status/review/assignee fields are
  ignored in the merged view (not deleted from relay history) and its
  legacy status-change/lifecycle controls are hidden, since BW alone
  governs its state; an unenrolled root stays a normal legacy issue.
  Pending/conflict notices are surfaced, never silently resolved.
- crates/buzz-core/tests/bw_desktop_bridge.rs runs the full pinned
  98-case/1804-step corpus through the exact desktop bridge, and
  additionally proves order-independence (reversed input) and
  reload/duplicate-event determinism (event list replayed twice)
  byte-for-byte against the same projection.

Self-review pass explicitly targeted negative/ordering cases: pagination
boundary-timestamp saturation fails closed rather than truncating
silently (unit-tested); the boundary re-fetch's incidental duplicate
rows are content-deduped by BTreeMap key and are also inert at the
Core layer (replay outcome); backward pagination progress is strictly
monotonic so it cannot loop. No UI-owned status latch, no automatic
actions, and no existing code path was deleted.

Verified before commit (all green, exact commands in the task
handoff): cargo test -p buzz-core/-p buzz-sdk/-p buzz-cli, cargo fmt
--all --check, cargo clippy -p buzz-core --all-targets -D warnings,
just desktop-tauri-{fmt-check,check,clippy,test}, pnpm --dir desktop
{typecheck,test,check}, scripts/check-nip-bw-fixtures.py,
scripts/test-nip-bw-fixtures.py, and a scoped Playwright run of every
touched UI surface (project-issue-comments, project-inbox,
project-pr-review, project-commit-detail, projects-v3-screenshots,
smoke). The 3 deterministic E2E failures and pnpm check's 3 format
findings in that run reproduce identically on unmodified HEAD
(verified via git stash) and are pre-existing baseline issues, not
introduced here.

Subject: [PATCH 48/76] feat(desktop): sign BW issue creation, triage and text
 updates (P4D)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds the write side of NIP-BW issue tracking on top of P4C's read
bridge: a single Tauri command (submit_project_bw_record) that signs
and readback-confirms issue-state/issue-update/triage-action records
through the already-fixture-tested buzz-sdk Publication boundary, so
role, causality, policy-binding and cutover checks are never
reimplemented client-side. Issue creation signs a 1621 root plus a
deliberate BW-enroll transition and surfaces (never hides) a partial
failure where the root exists but enrollment did not land. Fixed
bug/feature/operations templates require at least one acceptance
criterion before submit. Text/criteria edits and the four triage
actions chain off the exact current per-issue head and refuse to
submit into an already-forked chain, surfacing a visible conflict
instead of a silent overwrite. Fixed views group issues by
new/needs-clarification/backlog/in-progress/implemented, with visible
messaging for not-yet-enrolled, pending and conflicted history.

Kept the existing uncommitted draft's design and tests: it already
correctly excluded the legacy `p` tag from BW roots, delegated all
authorization to Core, and computed conflict/chain-head state from the
projection rather than guessing. Added: fixture-driven Rust tests that
exercise this command's own tag-assembly/record-building path against
the pinned NIP-BW corpus (role rejection, pre-cutover rejection,
successful enroll/update/accept) — proving a direct, scripted call
bypassing any UI is refused by Core, not by a hidden button; a mocked
`submit_project_bw_record`/configurable `get_project_bw` in the e2e
bridge; and a Playwright suite covering create+reload, missing
criteria, a double-submit race, a Core-refused triage action, a
concurrent text-edit fork, and a root that exists but was never
enrolled.

Pre-existing, unrelated to this change (verified via git stash against
unmodified HEAD before excluding): two failing desktop unit tests
(projectWorkItems review-authority status, the ProjectIssuesPanel
workflow-status-reason contract test), one flaky/failing Playwright
test (issue status from the detail rail), 3 pre-existing biome format
errors in issueStatus.ts/projectIssues.mjs/projectIssues.test.mjs, and
a file-size ratchet violation already present in lib.rs (+1 more line
from the new command registration) and three untouched files
(ChannelPane.tsx, ChannelScreen.tsx, UserProfilePanel.tsx).

+//! Signed NIP-BW record production for issue creation, text/criteria edits and
+//! triage actions (P4D). This is deliberately the *only* write path for the
+//! three record types it accepts: it signs and submits, it never decides
+//! authorization itself. Every candidate is validated by the same offline
+//! Core `Consumer` the read bridge (`bw_projection`, `commands::project_bw`)
+//! already uses, through the already-tested SDK `Publication` boundary
+//! (`crates/buzz-sdk/src/bw.rs`): role, causality, policy-binding and
+//! reference checks all happen there, not in this file. A direct call with a
+//! disallowed record type, a field a role cannot touch, a stale `previous` or
+//! a pre-cutover enrollment is refused here exactly as it would be refused if
+//! a UI button offered it — there is no separate, weaker gate for scripted
+//! callers.
+//!
+//! Legacy 1630-1633 issue status kinds are untouched and unreferenced here;
+//! see `project_issue_status.rs`. This module never routes through them.

Subject: [PATCH 49/76] feat(desktop): writer assignment, ready/dev/implemented
 handoff and relations (P4E)

Completes the desktop BW write surface P4D deliberately stopped short of:
assignment over the *existing* kind:1 wire (no new grammar), the
backlog->ready->in-development->implemented handoff, parent/child/
blocks/duplicate-of relations, and read-side display of all of it.

- crates/buzz-core/src/bw: projection now exposes issue_state/
  issue_state_id (the current issue-state head's own accepted body,
  verbatim) and leaf (executable-leaf eligibility). is_executable_leaf
  is factored out of the freeze-time membership check so the read-side
  projection and the freeze gate apply the identical parent/duplicate/
  blocker rule.
- desktop/src-tauri: new submit_project_bw_assignment command signs/
  submits an assignment or unassignment candidate over the existing
  issueAssignments.ts kind:1 grammar, delegating role/causality entirely
  to Publication::prepare. submit_project_bw_record gains the
  issue-relation record type and, for the implemented transition,
  resolves the real current commit of the bound stream via `git
  ls-remote` against the repository's own owner-signed clone URL and
  overwrites any caller-supplied commit/remote_readback before Core ever
  sees the candidate (NIP-BW.md: "the signed claim alone proves no
  remote fact"). sign_project_issue_status now refuses outright for any
  issue BW's own projection already shows a state for, closing the last
  path that could mutate a BW-enrolled issue through the legacy
  1630-1633 lifecycle.
- desktop/src/features/projects: bwWrite.ts adds
  submitBwAssignment/submitBwReadyTransition/
  submitBwInDevelopmentTransition/submitBwImplementedTransition/
  submitBwRelation, each computing only the previous/prior pointer from
  the already-fetched snapshot and refusing up front on a visible fork.
  bwProjection.ts adds bwAssignmentHead (mirrors bwChainHead's fork
  handling for the kind:1 assignment chain) and feeds the resolved
  writer into the existing assignee facepile instead of a parallel BW-
  unaware display. BwIssueActions.tsx adds the assignment section, the
  three transition actions, read-only implemented details and the
  relations list/add/remove UI, gated by issue.bw.state exactly like
  the existing triage actions.

Verified before commit: cargo test -p buzz-core/-sdk/-cli (267 passed),
cargo fmt --all --check, cargo clippy -p buzz-core/-sdk/-cli --all-targets
-D warnings, desktop-tauri-{fmt-check,clippy,check,test} (2474 passed),
pnpm --dir desktop {typecheck,test}, scripts/{check,test}-nip-bw-fixtures.py
(fixture SHA-256 b489fb18... unchanged), and a scoped Playwright run of
every touched surface (project-bw-issues, the new project-bw-assignment,
project-issue-comments, project-inbox, project-pr-review,
project-commit-detail, projects-v3-screenshots). pnpm test's 2
pre-existing failures and pnpm check's 3 pre-existing format findings,
plus 4 pre-existing Playwright failures (3 deterministic, 1 load-
dependent), all reproduce identically on unmodified HEAD (verified via
git stash) and are documented baseline issues from P4C/P4D, not
introduced here.

Not pushed yet: this touches signer/causality-adjacent code
(assignment authority, the git-readback evidence substitution), so it
waits for the Opus review the P4E task card requires for that surface
before publishing to the canonical stream.

+//! operation's `created_at` may sign; a first operation omits `prior`, every
+//! later one must reference the unique prior operation; assignment adds the
+//! sole delegate only when none currently exists, unassignment removes
+//! exactly the current delegate. None of that is decided in this file —
+//! `Publication::prepare` runs the identical role/causality checks
+//! `crates/buzz-core/src/bw/semantics.rs` applies to every other BW record,
+//! so a direct scripted call is refused exactly as a UI button would be.
+//!
+//! This command never selects the operation into a `ready`/`in-development`
+//! issue-state itself — that is a separate, Owner/coordinator-signed
+//! `issue-state` record submitted through `submit_project_bw_record`
+//! (`project_bw_write.rs`), matching NIP-BW.md's "Operations themselves do
+//! not change the active writer."

Subject: [PATCH 50/76] fix(desktop): close implemented-readback ref-shadowing
 found in P4E review
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

An independent Opus review of 72fd3ec3e (bound to that exact commit,
per the P4E task card's Assignment/Signer review requirement) found one
P1 and confirmed several other findings. This addresses the P1 and the
two cheapest, clearly-correct P2/P3 fixes; the remaining P2 findings are
reported separately as scope/product questions rather than silently
redesigned.

- P1 (fixed): `resolve_stream_head_blocking` took the first line of
  `git ls-remote <url> refs/heads/<stream>` output. ls-remote matches a
  pattern against the *tail* of a ref, anchored at a `/` boundary, so a
  ref pushed as `refs/heads/x/refs/heads/<stream>` also matches and can
  sort before the real branch. Anyone with push access to the repository
  — the assigned writer, by construction — could push such a shadow ref
  and have it accepted as the "externally observed" commit for their own
  implemented claim, defeating the exact guarantee this transition
  exists to provide. Now only a line whose own ref is byte-for-byte
  `refs/heads/<stream>` is accepted. Added a regression test that
  reproduces the shadow-ref push and confirms the resolver still picks
  the real head.
- P3 (fixed): `unsupported_operations_are_refused_before_any_network_call`
  in project_bw_assignment.rs was vacuous — it asserted a struct field
  equalled the value just assigned to it, never exercising the actual
  rejection. Extracted `validate_assignment_operation` as its own
  function and tested that directly.
- P2 (fixed): a forked/refused kind:1 assignment or unassignment
  candidate was invisible to the desktop UI — `bw_projection.rs` only
  ever surfaced a per-issue notice for 46100 records, and a conflicted
  event of either kind never reaches `accept` so it never appears in
  `records` either. Generalized notice attribution
  (`bw_projection.rs::notice_issue`) to also cover kind:1 assignment/
  unassignment candidates via their `e` tag, matching how 46100 records
  already attribute via their `issue` tag. Split the existing
  "competing assignment heads" Playwright test (which asserted a
  `records` shape the real backend cannot produce — the review correctly
  called this a false positive) into an explicitly-labelled defensive-UI
  test plus a new test proving the actual, now-reachable notice signal
  renders visibly.

Not changed here, reported to Jari as follow-up/product-decision items:
`sign_project_issue_status`'s BW-enrollment gate fails open on transient
`get_project_bw` errors and isn't bound to a specific issue/repo pair
(low practical impact per review); and `implemented` issue-state detail
(commit/tests/remote_readback) does not survive a reload today because
`project_bw.rs::load`'s `Evidence` is still the empty P4C placeholder —
consistent with P4C's documented "evidence collection is a later phase"
boundary, but worth an explicit decision before P4F's first real
issue-to-implemented run.

Verified: cargo test -p buzz-core/-sdk/-cli (267, including the full
1804-step pinned corpus via bw_desktop_bridge.rs), desktop-tauri test
(2475, +1 from the new regression test), fmt+clippy clean on both, pnpm
typecheck clean, and both BW Playwright specs (18/18) rebuilt and
passing.

From 2b280d2e6660fb3ebc57c3a5700ca7ffbdb2f636 Mon Sep 17 00:00:00 2001
From: Robi Hermes <robi.cholewa@gmail.com>
Date: Fri, 11 Sep 2026 15:01:03 +0000
Subject: [PATCH 51/76] fix(desktop): wrap submit_project_bw_record/assignment
 args in `input`
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Tauri binds command args by parameter name; both commands take a single
`input: SubmitBw*Input` struct param, so the wire shape must be
`{ input: {...} }`. Every caller sent the fields flat, so any real BW
write (enroll, triage, ready, in-development, implemented, assignment,
relation, text-update) failed in the built app with "missing required
key input" while the mocked e2e bridge — which never exercises Tauri's
real arg binding — stayed green. Update the two affected specs to
match the corrected wire shape.

Subject: [PATCH 52/76] feat(desktop): activate delegated BW triage-accept from
 the policy (P4F)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The desktop UI always submitted triage-action with delegate:false, so a
human holding a valid triage_delegation in the activated role policy
(issue, action, signer, expires_at) still failed with
bw:reject:role:unauthorized on click — Core and the Tauri write path
already handled delegate:true correctly, only the UI never set it.

BwTriageActions now derives delegate per action from the already-loaded
BW snapshot via a new bwMatchingTriageDelegation helper that mirrors
Core's own delegation match, using the current signer from the existing
identity query. No Core/backend change; RESERVED_CALLER_TAGS and
assemble_bw_tags are untouched.

Subject: [PATCH 53/76] feat(desktop): pick BW writer assignment by name
 instead of raw hex
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The BW issue panel's assignment section required typing a full 64-hex
delegate pubkey. Add a MentionAutocomplete-based picker (candidates
from the relay agent directory and the repo-bound channel's members,
resolved through the existing profile lookup) so a writer can be found
and assigned by display name/avatar; raw hex remains reachable via a
toggle for identities with no name to search by. The submitted
assignment payload is unchanged either way. The assignment header now
shows name/avatar/truncated pubkey instead of the naked hex, with the
full pubkey still available via the title attribute.

Split BwAssignmentSection out of BwIssueActions.tsx (now over the
desktop file-size ratchet) into its own file, sharing the small
invalidate/error helpers via bwIssueActionsShared.ts.

Left the "Stream (branch)" field as free text: the issue asked for a
dropdown of the five platform keys (windows/android/ios/macos/acp),
but the field's actual accepted value is a git branch name (e.g.
"windows-integration", per the existing e2e coverage and shape.rs's
"stream" validator) — collapsing it into the platform-key set would
submit a wire-incompatible value. Per the source issue's own note,
splitting this off as a separate finding rather than blocking the
picker.

Subject: [PATCH 54/76] feat(desktop): make BW ready stream a real-branch value
 help, not free text
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Point 4 of the picker issue (cb6885ba) is amended twice on the source
issue: Jari replaces the fixed five-platform-key list with a dynamic
value help sourced from the issue repository's actual branches (small
repos may have just one); Robi's follow-up corrects the single-branch
case to a read-only pre-filled field rather than an open dropdown.

Reuses the existing useRepoStateQuery (kind:30618 repo state, the same
remote-branch source git ls-remote would report) already used by
CreatePullRequestDialog — no new Tauri command or backend surface.
Multi-branch repos get a dropdown; a single branch is pre-filled and
read-only; an empty/unloaded branch list blocks submit outright, never
falling back to free text.

Subject: [PATCH 55/76] fix(desktop): block BW ready submit without a saved
 text update

NIP-BW's `ready` record requires a non-null `update` id naming the
issue's current text snapshot. An issue that has never had its own
`issue-update` record has no head to send, but `submitBwReadyTransition`
sent that null through anyway, failing Core's required `id` shape check
with the opaque `bw:reject:shape:schema` rejection instead of guiding
the user to save a text update first.

Subject: [PATCH 56/76] fix(desktop): refresh BW consumer clock before
 validating a new candidate
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

project_bw.rs::load captures `now` before its own network round trips
(paginated queries across five kinds, plus recursive reference
resolution). Against a real relay that can take longer than Core's
zero-tolerance references:future window, so a candidate signed right
after that load — using the actual current time — could look like it
arrived from the future purely because of how long the load took,
refusing every write with the opaque bw:pending:references:future.

Both BW write commands now call Consumer::observe to refresh `now` to
the signing instant right after replay, before evaluating the
candidate — the same mechanism project_bw_write.rs already used for
the implemented transition's evidence refresh, now applied
unconditionally and before, not after, activation/preflight.

Subject: [PATCH 57/76] fix(desktop): persist BW ready stream and auto-chain
 triage accept to backlog

BwReadyAction never seeded its stream selection from the issue's already
committed stream, so reopening an issue (or any re-render after an issue
switch) reset the dropdown to the first branch in the list regardless of
what was actually signed.

Separately, "Accept to backlog" only signed the triage-action record. Core's
own display projection already reports such an issue as "backlog" (a
convenience label in bw/projection.rs), but the issue-state chain itself
stays on "triage" until a second, Owner/coordinator-signed issue-state
record referencing that triage event lands (NIP-BW.md). Without it every
"ready" attempt was refused with bw:reject:causality:state-transition since
the real previous state was never "backlog". Chain that second record
automatically right after a successful accept so it is a single action for
the common owner/coordinator signer, instead of a separate manual step.

Subject: [PATCH 58/76] fix(desktop): heal issues stuck on triage when moving
 to ready
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

submitBwAcceptToBacklog's auto-chain (9936df38a) only fires on a fresh
"Accept to backlog" click. An issue already accepted before that fix
existed shows "Backlog" via Core's display-projection convenience label
but its real issue-state chain head never advanced past "triage" — and
the UI permanently hides the accept button once the label reads
"Backlog", so the missing backlog record could never be chained. Every
"ready" attempt on such an issue (e.g. ISS-064211C8) kept failing with
bw:reject:causality:state-transition.

submitBwReadyTransition now detects a real chain head still on "triage"
and signs the missing issue-state(backlog) record itself, using the
existing triage-action accept head, before signing ready — still a
single "Move to ready" click, no extra UI step.

 To assign an issue to someone, run `buzz issues assign --issue <event-id> --repo-owner <hex> --repo-id <id> --assignee <hex> --label <name>` after creating it. Remove an assignment with the matching `buzz issues unassign` arguments. Writing assignee names in the issue body or adding recipients with `issues create --to` is notification/presentation only — Buzz Desktop's Assignees rail and the "Assigned to me" filter read the signed assignment operations. Only operations signed by the issue author or repo owner are trusted for other people; anyone may assign or unassign themselves.
 
+When Buzz asks you to start a ready BW issue, run the exact `buzz issues start-development --issue <event-id> --repo-owner <hex> --repo-id <id>` command from the request before editing. It reloads the repository's BW history and succeeds only when your own agent identity is still the selected writer; an owner-auth tag never substitutes the owner's role for your event signer.

 ## Conversational Agent Creation
 
 When someone asks to create an agent, ask for at most two things: the agent's name and what it should do day-to-day. Turn the user's rough purpose into the `--system-prompt` yourself; do not separately ask for purpose, tone, constraints, access, runtime, provider, or model unless the user's request is genuinely ambiguous.

Subject: [PATCH 73/76] feat(desktop): render read-only BW release views

P5_6A (issue 35a572b21560bff16030db1428375f27f2e57857cad41ab3c6de10a964fc310a):
read-only Releases workspace tab over the existing get_project_bw Core
projection. Set status comes verbatim from projection.sets, verdicts from
projection.artifact_verdicts, the current handoff from projection.handoffs,
details from Core-accepted records, and pending/refused chains from
decisions/conflicts as traceable event references. No side-effecting
control; missing external evidence stays visibly pending; a provider run
success never upgrades anything to completed.

Desktop tests render Core-authored snapshots only: an env-gated export in
bw_desktop_bridge replays pinned NIP-BW.fixtures.json cases
(SHA-256 b489fb188b45e073e81783e8d591f24891a9c73bc56d8d2fc56a881606640e8a,
unchanged) through the real Core consumer into
bw-release-snapshots.json, fed through the existing transient BwSnapshot
E2E mock seam. Covers empty set, run pending/failure, digest mismatch,
non-durable download, late events, historically accepted issues with a new
unreviewed artifact, and conflicting verdicts.

Subject: [PATCH 74/76] ci(windows): allow explicit commit-bound manual test
 builds

Keep the signed BW pipeline unchanged. Extend the existing canary with a fork-only canonical SHA gate, cumulative ancestry, unsigned artifact receipt and CRLF regression. Authorized directly by Jari; no release, BW status or acceptance mutation.
