bfc3848558 fix(desktop): shared npub identity foundation (canonicalNpub, PubKey gate, strict parser) (#7488)
🤖
## Summary

Identity keys in the desktop app are displayed as raw 64-character hex.
A person's key shows up as something like `953d3363…` — unreadable,
impossible to recognize as the same identity on another screen, and a
hazard when copied by hand. Nostr (the protocol Buzz runs on) has a
human-readable spelling for identity keys — the `npub1…` form — but the
desktop app did not use it consistently.

This is the foundation of the desktop npub changes: it adds the shared
pieces every identity surface builds on, and two follow-up slices stack
directly on this branch — #7489 converts the identity controls (profile,
settings, allowlist, workflow key fields) and #7495 converts the
everyday display surfaces (mentions, member lists, sidebar, and other
name fallbacks).

After this change:

- The shared identity widget shows the compact npub form —
`npub1j57...fjmv` — instead of a hex prefix, everywhere it renders (for
example the owned-agent public-key row on a profile). Copying it puts
the full npub on the clipboard.
- Copy is a real interaction, verified end-to-end: both popover variants
put the exact canonical npub on the actual clipboard — never the raw hex
the popover also lists, never a truncation — and a portaled popover's
clicks no longer steal focus from the new-DM To-field mid-copy. Pointer
copy, a natural Space-then-Enter path, and inner/outer Escape are
covered.
- Anything that isn't a valid identity key fails neutrally: short or
corrupt values — including degenerate values that technically encode to
a checksum-valid npub but aren't real identity keys — show "Unavailable"
with no copy button, instead of a misleading value.
- Both valid npub spellings display: all-lowercase `npub1…` and
all-uppercase `NPUB1…` (Bech32, npub's encoding, permits either casing)
both render the same canonical lowercase npub. Mixed case is rejected by
the display path as written — `canonicalNpub` and the widget don't
case-normalize input — while input parsing (`parsePubkeyInput`) keeps
its trim-and-lowercase normalization and accepts mixed-case npubs; both
paths require the decoded payload to be exactly a 64-character identity
key.
- Identity-key input is strict on payload: an npub whose decoded payload
isn't exactly a 64-character identity key is rejected, matching the
validation the app's Rust side already applies to agent allowlists.

Intentional scope boundary: only surfaces that render through the shared
widget change here. Outer profile copy, settings identity cards, the
respond-to allowlist, and workflow key fields still show hex — they move
to npub in the controls follow-up (#7489). Nothing else changes identity
representation: display names, private keys, event IDs, and the hex the
app stores, sends, and matches internally are untouched; only the
user-facing spelling of an identity key changes.

## Details

- `desktop/src/shared/lib/pubkey.ts` — `canonicalNpub()`: strict
canonical full-npub helper (64-char hex in any case, or a
checksum-validated npub, returns the canonical npub; anything else
returns `null`); `truncateNpub()`: the compact display form; existing
exports unchanged.
- `desktop/src/shared/ui/PubKey.tsx` — the shared widget's identity gate
validates through `canonicalNpub`; the popover copies the npub only.
- `desktop/src/shared/lib/nostrUtils.ts` — `parsePubkeyInput` rejects
npubs whose payload is not exactly a 64-character identity key.
- `desktop/src/features/messages/ui/NewMessageScreen.tsx` — the To-field
focuses its search input only for clicks that land inside the field
itself, so portaled recipient popovers keep their focus while open (a
popover click previously dismissed it mid-copy).
- Unit suites cover the helper, widget, and parser (including the
degenerate-encode and uppercase regressions); the e2e specs that render
these rows assert the npub display.

### Related issue

- Fixes: N/A. Searched existing issues/PRs for npub identity display —
no existing match.
- Stack: #7489 is based on this branch and builds on these primitives;
it does not stand alone on main.

### Testing

At head `b3310c248` (base: main `44316ff72`; 12 files, +440/−39):

- Focused unit suites (pubkey, PubKey, parsePubkeyInput): 20/20 green;
mutation-checked — removing the decoded-length predicate fails the
short/empty checksum-valid-npub assertions in `canonicalNpub` and the
widget, and a wrong-identity clipboard value fails the new copy
assertions.
- `pnpm typecheck` and `pnpm check`: pass; full desktop unit suite
6459/6459 at this exact head.
- Targeted e2e at this exact head: 8/8 across the two specs that own the
clipboard flows — `agent-access-warning.spec.ts` (compact variant,
agent-access owner hint) and `pubkey-display-screenshots.spec.ts` (full
variant, new-DM recipient verification: pointer copy, popover surviving
the copy, inner/outer Escape, Space-then-Enter).
- No Rust-side or build files change in this PR, so those results are
unaffected.

f716eef437 fix(desktop): enforce shared agent access across devices (#6086)
## Summary

- discover shared managed agents from authenticated relay directory
records instead of treating channel membership as sufficient proof
- publish and refresh access-policy changes immediately so running
clients converge across machines without a restart or five-minute poll
- route profile edits through the exact managed instance and
stop/restart runtimes around access changes so unrelated edits cannot
silently widen access
- keep mention send-time revalidation and Block owner-only build
enforcement fail closed
- explain invalid custom provider/model configuration instead of leaving
Save silently disabled

### Related issue

Fixes #3204

### Known residuals

- a brand-new remote agent's first policy record can wait for the
bounded directory poll when no authenticated directory coordinate exists
yet; send-time mention revalidation remains fail closed
- a failed remote-provider policy redeploy is recorded but cannot
undeploy the older provider instance until the provider protocol gains
the destructor tracked by #5570

### Testing

- full Desktop unit suite: 4,961 tests passed
- focused profile editor Playwright workflow passed, including Customize
access edits and prompt-only edits after tightening an instance
- Desktop TypeScript, Biome formatting, file-size ratchet, Tauri checks,
and pre-push suites passed
- independently reviewed for authenticated directory trust, live
subscription teardown, runtime revocation ordering, fail-open edit
paths, and per-agent provider deployment serialization

7fb008f934 fix(desktop): explain open agent access (#2561)
## Why

Hack-day feedback exposed a dangerous mismatch between the UI and the
underlying access model. The `Anyone` respond-to mode appeared as a
neutral dropdown choice, while a Buzz agent may act with the files,
accounts, and tools available on the machine where it runs.

People reasonably read this as sharing a bot in a channel. The current
UI did not explain that it can also share the agent's available access.

## What

- Reframes `respond-to` as **agent access** in user-facing UI.
- Uses plain audience labels: **Only me**, **Anyone**, and **Selected
people**.
- Warns for **both** sharing modes, not just `Anyone` — `Selected
people` also hands host access to someone other than the owner, so only
the audience phrase differs:
> Anyone can use this agent to access your computer, including files,
accounts, and connected tools.

> Selected people can use this agent to access your computer, including
files, accounts, and connected tools.
- Names the machine the agent actually runs on. A provider-backed
(remote) agent reads:
> Anyone can use this agent to access the server it runs on, including
any accounts and tools available there.

The remote wording deliberately omits the owner's files — those aren't
theirs to describe on a host they don't own.
- Places the warning below the selector for `Anyone`, but **after** the
people picker for `Selected people`, so it never sits between the user
and the selection they came to make.
- Removes Nostr, harness, pubkey, and `!shutdown` jargon from the
primary decision copy. Direct pubkey entry remains available as an
advanced path.
- Replaces the green open-access avatar dot with an amber warning marker
and accessible text. Selected access uses a separate blue status.
- Aligns the sidebar action and profile field with the same language.
- Records the shared-field disclosure contract in
`desktop/src/features/agents/AGENTS.md` so future surfaces do not
silently omit it.

## Design decisions

**Persistent inline warning, not a confirmation modal.** The setting
does not autosave; the consequence remains visible beside the selection
until the person chooses **Save access**. This gives the information
before commitment without adding a dismiss-and-confirm ritual that would
repeat in every create/edit surface.

**An unknown run location falls back to the local wording.** It does not
hedge with "computer or server". A remote host requires an installed
`buzz-backend-*` provider, and without one `WhereToRunSection` never
renders — so "server" would name a concept the owner has never been
shown. When it *is* remote, they picked that host from the selector
themselves. Surfaces never synthesize a run location they don't have.

**One resolution site, published through context.** `AgentDialog`
resolves the run location (`runLocationForBackend` from
`ManagedAgent.backend`, `runLocationForRunOn` from the create flow's
`WhereToRunDraft`) and publishes it via `AgentRunLocationContext`. It is
not threaded as a prop through `AgentDefinitionDialog` (1047 lines) or
`AgentInstanceEditDialog` (1228 lines) — neither uses the value, and
both are already over the file-size ceiling. Surfaces outside that tree
(`EditRespondToDialog`) pass the prop directly.

The copy follows the writing system's guidance for high-sensitivity
decisions: lead with the material consequence, use plain actor/action
language, keep helper text adjacent and persistent, and never rely on
color alone.

## Scope

Desktop only. The web and mobile clients do not currently expose this
setting. No protocol, gate, runtime, persistence, or backend behavior
changes.

This does not add team-scoped remote agents. It makes the current
local-or-remote access model honest while that product work remains
separate.

## Validation

- `pnpm exec biome check` and `pnpm exec tsc --noEmit` — clean
- `lib/agentAccessWarning.test.mjs` (8/8) — every mode × run-location
copy variant, both resolvers, unknown-reads-as-local, blank `runOn` is
not a provider
- `ui/respondToFieldContract.test.mjs` (8/8) — plain labels, both
warning positions, source-order guard that the `allowlist` warning
follows the picker, helper-not-inline-copy guard
- `agent-access-warning.spec.ts` (3/3) — native local, provider-backed
remote (asserts the server sentence and *not* "your computer"),
persona-backed edit; includes a bounding-box check that the `Selected
people` warning renders below the picker
