## Problem
`common_binary_paths()` probes mise shims, `~/.local/bin`, volta, asdf,
and (further down `resolve_command_uncached`) nvm's default bin dir —
but not bun's global bin directory, `~/.bun/bin`.
bun's installer appends its bin dir to `~/.zshrc` / `~/.bashrc`, which
are **interactive**-only. A login shell never sources them, so
`find_via_login_shell()` can't recover the path either. That's the same
failure mode already called out in this file for nvm:
```rust
// Check nvm's default Node.js bin directory — nvm initializes via
// ~/.zshrc (interactive) which is not loaded by a login shell, so
// `node`, `npm`, and npm-global shims installed there are otherwise
// invisible.
```
So for a GUI-launched desktop app, every rung of the resolution ladder
misses a bun-installed CLI:
1. workspace dev dirs — no
2. `command_looks_like_path` — no, presets use bare names
3. Buzz-managed npm/node dirs — no
4. current process PATH — launchd's minimal PATH on a Finder launch
5. `find_via_login_shell` — `.zshrc` not sourced
6. `common_binary_paths()` — **`~/.bun/bin` absent**
7. nvm default bin — no
This matters because bun is a common install route for the agent CLIs
Buzz targets. Kimi Code in particular ships as an npm package
(`@moonshot-ai/kimi-code`), so `bun add -g` puts it at `~/.bun/bin/kimi`
— exactly where discovery doesn't look.
## Reproduction
On macOS with `codex` and `kimi` installed via bun, launching Buzz from
Finder:
- Kimi Code shows **"CLI needed"**
- both CLIs run fine in an interactive terminal
Probing the way `find_via_login_shell` does, in a clean environment:
```console
$ env -i HOME=$HOME /bin/zsh -l -c 'command -v -- codex; command -v -- kimi'
(nothing)
```
Launching the app with the bun dir on PATH resolves both immediately:
```console
$ env PATH="$HOME/.bun/bin:$PATH" /Applications/Buzz.app/Contents/MacOS/buzz-desktop
```
## Change
One entry appended to the home-relative list in `common_binary_paths()`.
It goes **last** so it cannot shadow a directory that already resolves —
the change can only add resolutions, never alter existing ones.
## Testing
`cargo fmt --check` passes.
I was not able to run the full `just ci` gate locally: `ring 0.17.14`
fails to build in this environment against the macOS 26.2 SDK (`cc`
error compiling `p256-nistz.c`), which is unrelated to this change.
Relying on CI for the rest — the diff adds one `PathBuf` to an existing
`Vec<PathBuf>` and introduces no new API.
## Notes
- Related to #3084, which adds `~/.kimi-code/bin` for the same class of
GUI-launch discovery failure. That covers Kimi's standalone installer;
this covers the bun/npm-global install route. They're complementary —
I've left a note on that PR.
- Only `~/.bun/bin` is added. bun's global packages live under
`~/.bun/install/global/node_modules` but are symlinked into
`~/.bun/bin`, so the single directory is sufficient.
- Worth noting `~/.bun/bin` contains no `node`/`npm`/`npx`, so appending
it can't shadow a system Node toolchain.

## Summary
Agent-authored mentions currently depend on matching visible `@Name`
text to channel profiles. That makes notification delivery ambiguous
when names collide or profiles change, and it encourages an extra
post-send lookup just to confirm that the intended `p` tags were
emitted.
This change makes `buzz messages send` mirror Desktop's existing model:
the message keeps a readable name in its content while the recipient
pubkey is supplied separately.
```bash
buzz messages send \
--channel <UUID> \
--content '@Alice could you review this?' \
--mention <alice-hex-or-npub>
```
`--mention` is repeatable. The CLI normalizes and deduplicates explicit
pubkeys, merges them with any names it can resolve from the channel, and
gives explicit identities priority under the existing 50-mention limit.
Before uploading attachments, signing, or publishing, the command checks
every resulting pubkey against the channel's current membership:
- Members are mentioned normally.
- Non-members stop the send and produce an actionable error.
- `--allow-non-member-mentions` deliberately sends notifying `p` tags
without adding anyone to the channel.
Sending a message never changes membership. On success,
`mention_pubkeys` is read from the exact signed event and returned with
the relay response, so callers can verify the emitted recipients without
another query.
Managed-agent guidance teaches this single-command mention flow. Desktop
mention behavior and the Nostr event schema are unchanged. Forum
guidance is intentionally handled separately in #3596.
### Related issue
None found. This replaces the earlier guidance-only approach in this PR
with the underlying CLI behavior it required.

## Summary
Fixes two distinct fidelity failures in direct agent sharing:
- The sender now puts the same effective avatar shown on the agent card
into People-share and file-export snapshot PNGs, including
profile/kind:0 fallback avatars.
- The importer now persists the visible PNG body as the portable avatar
instead of ignoring it in favor of sender-local manifest references.
- Export materializes inherited runtime, provider, and model identifiers
verbatim, while preserving explicit definition values. It does not
translate or substitute configuration for a different recipient setup.
- Sharing waits for a profile-only fallback avatar query, preventing an
early-click race.
The PNG import path keeps the existing safety invariant: decode is
capped at 2048×2048 / 32 MiB and re-encoded avatars above the 2 MiB
inline limit fall back to the manifest reference. The exact transparent
1×1 no-avatar placeholder is ignored.
The original Tyler↔Wes screenshot demonstrates both stages: Wren's
attachment had an avatar that disappeared after **Add agent**
(receiver/import failure), while Pinky's attachment was already blank
(sender/projection failure).
### Related issue
N/A — reported and traced in the linked Buzz conversation.
### Testing
- `cargo test --manifest-path desktop/src-tauri/Cargo.toml
commands::personas::snapshot` — 57 passed
- `pnpm exec tsc --noEmit`
- Biome check on changed frontend/E2E files
- Pre-push hooks:
- desktop check
- desktop tests
- desktop Tauri tests — 1853 passed, 14 ignored
- file-size ratchet
The People-share E2E regression asserts that a profile-only avatar
reaches `avatarPngDataUrl` in the real encode command payload.

The codex adapter version gate accepted any `major >= 1`, so a 1.x
`codex-acp` older than the version that fixes outbound relay access for
`buzz` CLI subprocesses classified as `Available` and was never offered
a reinstall. Only the 0.16.x `@zed-industries/codex-acp` adapter — which
fails `--version` outright — was caught.
`probe_codex_acp_version` now returns the full `(major, minor, patch)`
triple and `codex_adapter_availability` compares it against a new
`MIN_CODEX_ACP_VERSION` floor of `1.1.7`, the current npm latest. An
adapter below the floor classifies as `AdapterOutdated`, which routes it
through the existing uninstall-then-install reinstall plan.
The parse requires exactly three numeric dot-separated components.
Partial versions (`1.2`) and prerelease tags (`1.2.0-rc1`) return `None`
and therefore classify as `AdapterOutdated` — a version Buzz cannot
compare against the floor fails closed, offering a reinstall rather than
running an adapter of unknown vintage. Both the floor's bump policy and
the strict-parse behavior are stated in doc comments rather than left
implicit.
Supersedes [#3097](https://github.com/block/buzz/pull/3097) by
@Bharathchinneni, whose semver floor and behavior tests this carries.
That PR could not land as written: the two
`probe_codex_acp_major_version` compatibility wrappers it kept had no
non-test callers, which is a hard `clippy -D warnings` failure. The
wrappers are deleted here and their call sites collapsed onto
`probe_codex_acp_version`.

Goose's pre-[#2680](https://github.com/block/buzz/pull/2680) Windows
installer unpacked the CLI to `%USERPROFILE%\goose\goose.exe`. That
directory is on no standard `PATH`, and `common_binary_paths()` never
probed it, so users who installed Goose with the legacy installer stayed
permanently undiscovered — the residual half of #2239.
`resolve_command_uncached` finds binaries outside `PATH` only by
scanning `common_binary_paths()`, so adding the directory there is the
whole fix: Windows basename expansion already supplies
`goose.exe`/`.cmd`/`.bat`, and discovery, readiness probes, and spawn
all route through the same shared resolver. No Goose-specific resolution
path is introduced. The entry sits beside the existing Codex
`%LOCALAPPDATA%\Programs\OpenAI\Codex\bin` probe in the same
`#[cfg(windows)]` block.
The regression test is `#[cfg(windows)]` and is CI-reachable, not dead
code — the `desktop-build-windows` job runs `cargo test --manifest-path
desktop/src-tauri/Cargo.toml --target $env:TARGET` on `windows-latest`.
It asserts the probe list rather than planting a binary:
`common_binary_paths` is a process-lifetime `OnceLock`, so a test cannot
deterministically re-seed `USERPROFILE`, and planting an executable
under the real user profile is not an acceptable side effect. Verified
locally by widening the `cfg` to build on macOS — the test passes with
the probe and fails without it.
The `check-file-sizes.mjs` override for `managed_agents/discovery.rs`
moves 1835 → 1841, the exact post-`cargo fmt` gate count. Verified both
directions: 1841 passes, 1840 fails.

## Problem
User report:
```
Buzz Node mismatch: Buzz supplies Node 24.14.0; OpenClaw requires >=24.15.0. All 10 ACP workers immediately crash.
```
Buzz supplies Node to agent processes from two places, and both were
below OpenClaw's floor:
| Supply path | Was | Now |
|---|---|---|
| hermit dev env (`bin/.node-*.pkg`) — the 24.14.0 in the report |
24.14.0 | **24.15.0** (newest hermit publishes; satisfies `>=24.15.0`) |
| Desktop managed runtime (`managed_node.rs` / `managed_node_paths.rs`)
| v24.11.0 | **v24.18.0** (current latest v24) |
The managed runtime sits **first** on the worker PATH
(`managed_agents/runtime/path.rs`), so a user-installed newer Node can't
mask a stale managed one — the pin itself has to move.
## Verification
- SHA-256 digests for all six platform artifacts taken from
`https://nodejs.org/dist/v24.18.0/SHASUMS256.txt`; darwin-arm64
independently re-verified by downloading the tarball (hash match),
extracting, and running `bin/node --version` → `v24.18.0`.
- All artifacts within `MANAGED_NODE_MAX_BYTES` (largest linux-x64 at 57
MB < 90 MB cap); tar.gz layout keeps the `node-vX-platform/bin/node`
shape `verify_node_tree` expects.
- `cargo test --lib` in `desktop/src-tauri`: **1801 passed, 0 failed**
at this commit; `cargo fmt --check` + `cargo clippy --lib -D warnings`
clean.
- Existing readiness check (`node --version == MANAGED_NODE_VERSION`)
makes upgrade automatic: installed v24.11.0 trees fail readiness and the
installer stages v24.18.0 atomically (rename with `.old` rollback —
existing logic, unchanged).
Note: CI `node-version: 24.14.1` pins in
`release.yml`/`windows-canary.yml` are build-env only (already `>=`
nothing OpenClaw touches) and left alone to keep this minimal.

## Problem
Part of #2423 (renaming personal agents desynchronises identity).
Renaming an agent definition (persona) propagates the new display name
to its
linked agent instances (`propagate_persona_name_rename` in
`desktop/src-tauri/src/commands/personas/mod.rs`) and saves
`managed-agents.json` — but, unlike the instance-rename path
(`update_managed_agent`), it never re-retains the renamed instances'
kind:30177
managed-agent identity records. `record.name` is part of the published
identity
projection (`agent_event_content`), so after a persona rename:
- `managed-agents.json` says the NEW name,
- the retained kind:30177 row (retention.db → relay flush loop) still
carries
the OLD name, with the OLD `created_at`.
The stale identity record stays live on the relay until the next app
launch,
when the boot-time reconcile (`reconcile_agents_in_dir`) finally notices
the
content diff and republishes. Until that restart, any surface that
resolves
agents from kind:30177 records (second desktop of the same owner, CLI,
other
NIP-AP clients) sees the OLD name bound to the agent pubkey while the
kind:0
profile already shows the NEW one — the name→identity binding desync
described
in #2423, and consistent with the report's observation that repairing
state
required "a separate restart".
## Fix
- Extract the per-record retain body of the boot reconcile into
`managed_agents::reconcile::retain_agent_record(conn, keys, record) ->
Result<bool, String>`
— one shared content-diff + monotonic-`created_at`-bump engine (returns
whether a row was rewritten). `reconcile_agents_in_dir` now calls it per
record (behavior unchanged; existing reconcile tests still pass).
- `commands::agents::retain_managed_agent_pending` delegates to the
shared
engine instead of carrying a duplicate implementation (same semantics:
projection-equality no-op guard, monotonic bump, `pending_sync = 1`).
- `update_persona` (Phase 1, still under the store lock, after
`save_managed_agents`): call `retain_managed_agent_pending` for every
record
the rename propagated to — mirroring `update_managed_agent`. Avatar-only
edits are deliberately excluded (the avatar is not part of the
kind:30177
projection; retaining would be a guaranteed no-op).
No new events, kinds, or APIs — this uses the existing signed-event
retention
and flush pipeline, per CONTRIBUTING's guidance to prefer a signed Nostr
event
and the existing ingest path over endpoint-specific JSON APIs.
## Out of scope (deliberately)
- Rename → runtime restart is #1823, fixed by open PR #2507
(spawn_hash).
- Surfacing kind:0 relay profile-sync failures on rename is PR
#2302/#2279
territory (and largely superseded by the merged rollback in #2258).
- Mention-picker UX (owner/status disambiguation) and channel-membership
repair for stale identities: TS-side, noted in #2423, not touched here.
## Test evidence
Two new unit tests in
`desktop/src-tauri/src/managed_agents/reconcile/tests.rs`
(same harness as the existing reconcile tests — tempdir + retention.db +
fresh
keys, no AppHandle):
- `rename_re_retains_identity_record_with_new_name` — retain "Fizz",
confirm
flush, rename to "Spark", re-retain: row keeps the pubkey coordinate,
carries the new name only, is `pending_sync`, and its `created_at` is
strictly past the retained head (replaceable-event acceptance).
- `retain_agent_record_is_noop_when_unchanged` — an unchanged projection
does
not rewrite the row and produces zero `pending_sync` churn.
Ran scoped per CONTRIBUTING build discipline (from `desktop/src-tauri`):
```
cargo fmt -p buzz-desktop # applied, clean
cargo clippy -p buzz-desktop --lib --tests -- -D warnings # exit 0, no warnings
cargo test -p buzz-desktop --lib # full lib suite
```
Full `buzz-desktop` lib suite: **1562 passed, 0 failed, 13 ignored** —
including all 12 `managed_agents::reconcile` tests (10 pre-existing, all
unmodified in behavior, plus the 2 new regression tests above).

## Reproduction steps
1. Open Settings → Agents and inspect Agent runtimes; ready, signed-out,
installable, and setup-required runtimes should have stable rows and
explicit actions.
2. Open Add runtimes and browse the Setup and Installed groups; select
entries to see sourced guidance and a pinned Install or Setup guide
action.
3. Select Custom harness, create a runtime, then edit and delete it;
verify required-field gating and the blast-radius confirmation.
4. Exercise a signed-out runtime and connect it; the row should move
from Sign-in needed to Ready without reordering.
5. Resize the window and switch themes to verify responsive layout and
adaptive bundled marks.

## Problem
On Windows, Projects **Remote** view shows an empty file tree and
Sync/Clone fails with a mangled credential-helper path, for example:
```
C:\Users\<user>\AppData\Local\Buzz\git-credential-nostr.exe get: line 1:
C:Users<user>AppDataLocalBuzzgit-credential-nostr.exe: command not found
fatal: could not read Username for 'https://<relay>/git/...': terminal prompts disabled
```
Buzz injects an absolute path into `credential.helper` via
`Path::display()`. On Windows that yields backslashes. Git for Windows
runs credential helpers through MinGW bash, which treats `\` as escapes
and destroys the path, so NIP-98 auth never runs and the blobless temp
clone behind Remote view fails.
macOS/Linux are unaffected (paths already use `/`).
This is unrelated to shipping a stub helper - the bundled
`git-credential-nostr.exe` is a real binary. User `~/.gitconfig`
workarounds also cannot help here because Projects git sets
`GIT_CONFIG_GLOBAL=/dev/null` and injects its own helper.
Closes#3025
## Fix
Normalize the helper path to forward slashes before writing
`GIT_CONFIG_VALUE_*`:
- `desktop/src-tauri/src/commands/project_git_exec.rs` (Projects Remote
/ Sync)
- `desktop/src-tauri/src/managed_agents/runtime.rs` (agent spawn git
auth)
Forward slashes are accepted by Git on every platform; on macOS/Linux
the replace is a no-op. No `cfg(windows)`, packaging, or libgit2
changes.
## How to reproduce (before)
1. Install Buzz on Windows with Git for Windows
2. Connect to a relay that has a repository with at least one pushed
branch
3. Open **Projects** -> select the repo -> **Remote**
4. Observe empty tree; Sync/Clone shows the mangled-path / `command not
found` error above
## Test plan
- [x] Unit: `cargo test --manifest-path desktop/src-tauri/Cargo.toml
credential_helper_config_value` (formatter covered on all platforms;
no-op for Unix-style paths)
- [x] Local Windows NSIS build + install of this branch
- [x] Projects -> Remote / Sync against a Buzz relay repo succeeds on
Windows after the fix

ACP harnesses that name a session from the first text they receive all
land in the same place: every managed Buzz agent opens with the
identical `[Base] You are operating inside the Buzz platform…` framing,
so the harness session list shows a wall of indistinguishable rows.
Because sessions are keyed per channel, one agent active in several
channels produces several of them.
This sends the name out of band instead. `session/new` carries
`_meta.sessionTitle` with `Agent · #channel`, composed from the agent's
`display_name` (or its unique `name` handle) and the channel it is
serving. The prompt is untouched — no tokens spent, no perturbation of
the prompt contract, and nothing new for the desktop observer's section
parsing to handle.
The mechanism is harness-agnostic: Buzz sends the field on every ACP
`session/new` regardless of which harness is behind it, and adapters
that don't read it ignore it per spec.
## Inert until a consuming adapter ships
ACP adapters ignore `_meta` members they do not recognize, so against an
adapter with no reader a Buzz session gets no title and nothing else
changes. Three adapter halves consume it — Codex, Goose, and Claude Code
(linked below); this half and each reader are only useful together, and
each reader lands independently.
No version floor is added. `codex_adapter_is_outdated_with_path` already
gates codex-acp on major version `>= 1`
(`desktop/src-tauri/src/managed_agents/discovery.rs:1276-1284`) and this
feature needs nothing above that — an older adapter is not broken by the
extra member, it simply ignores it.
## What changes
**`crates/buzz-acp`** owns sanitization and composition.
`sanitize_session_title` collapses whitespace, drops control characters,
and caps at `SESSION_TITLE_MAX_CHARS` (80) by character, not byte, so a
multi-byte character cannot be split. `compose_session_title` truncates
only the channel part against that cap, so the agent name always
survives; when the agent name alone fills the cap the channel is dropped
rather than the name. `session_new_full` sets `_meta.sessionTitle` when
a title exists and omits `_meta` entirely when it does not, since an
adapter may distinguish an absent member from a null one.
**`desktop/src-tauri`** only resolves and exports.
`resolve_session_title` picks `display_name` or falls back to `name`,
and `spawn_agent_child` writes it to `BUZZ_ACP_SESSION_TITLE` — or
removes the variable when neither candidate yields anything printable.
DMs, unresolved channels, and heartbeat sessions get the bare agent name
with no channel suffix.
## Four properties that are easy to remove by accident
**Control characters are stripped at the desktop boundary, not in the
harness.** An interior NUL cannot cross the environment boundary at all
— `Command::env` fails the entire spawn rather than passing it through.
Deferring the strip to `buzz-acp` would let a corrupted display name
turn display chrome into a spawn failure. A display name that is *only*
control characters falls back to `name`.
**The title is hashed into `spawn_config_hash`.** Without it, renaming
an agent left the running process with a stale title and no restart
badge. The hash runs the same `resolve_session_title` the spawn writes,
and skips it when a user env override shadows `BUZZ_ACP_SESSION_TITLE` —
spawn writes the title *before* the layered user env, so the override is
what actually runs, and it already reaches the hash through
`descriptor.env`. Hashing the record-derived value under an override
would badge a rename that changes nothing.
**One channel resolve serves both consumers.**
`resolve_new_session_channel_context` returns `(is_dm, title_channel)`
from a single metadata lookup, feeding both the canvas block's DM check
and the title. `ChannelInfoResolver` caches only `Some`, so two
independent calls against an unresolvable channel pay the full
`fetch_channel_info` retry sequence twice — two timeouts plus a retry
delay each — directly in front of `session/new`, precisely when the
relay is already degraded.
**The `"unknown"` channel name is treated as absent.**
`fetch_channel_info` substitutes the literal `"unknown"` for a metadata
event with no `name` tag. Composing that sentinel would title every
unnamed channel `Agent · #unknown`, reintroducing the exact collision
the suffix exists to remove while naming a channel something it isn't.
The startup cache already refuses `channel_type == "unknown"` for the
same reason.

Harnesses became per (agent, relay) pair in #2122 and now write
`agents/logs/{pubkey}__{sha256(relay_url)}.log` via
`managed_agent_runtime_log_path`. `get_managed_agent_log` was never
updated and still read the legacy `agents/logs/{pubkey}.log`, so agent
profile → Runtime → Harness Log froze at each agent's last
single-runtime line while live output accumulated in files the reader
never opened.
The reader now resolves the log through `latest_managed_agent_log_path`,
which picks the most recently modified file belonging to the agent —
pair-scoped `{pubkey}__*.log` or legacy `{pubkey}.log` — and falls back
to the legacy path when the agent has no log on disk at all. Agents that
have not restarted since the update keep working, and the panel follows
whichever harness is currently writing. The response already carried
`log_path`, so the panel header names the file being shown.
Selection is deterministic: equal mtimes break toward the higher
filename, and files belonging to other agents or without a `.log`
extension are never candidates.
`storage.rs`'s inline test module moves to a `#[path]`-included sibling
`storage_tests.rs`, matching the existing pattern in `teams.rs` and
`archive/mod.rs`. This drops both halves under the desktop file-size
limit (1383 → 826 / 701), so the ratchet entries tighten instead of
growing.

Uses MeshLLM built-in `mesh` collective intelligence / Mixture of Agents
when Buzz Auto sees two or more distinct physical models. With zero or
one model, Auto remains ordinary `auto`. This is an alternative way to
improve tool responses, accuracy, and resistance to hallucination when a
high-latency distributed mesh contains diverse models.
Models and members may come and go: collective routing enables only
after stable capacity, drops on confirmed contraction, and can recover
later. Mesh-specific failures retry once through ordinary Auto.
This update also pins MeshLLM to a v0.73.1-compatible backport of
[MeshLLM #1074](https://github.com/Mesh-LLM/mesh-llm/pull/1074), so
client-only Buzz nodes cannot enter model election or download a remote
provider model. Buzz preserves the selected local sharing model and
switches an existing client to sharing across a controlled app restart,
retaining one runtime and one `:9337` / `:3131` pair per machine.
Validation:
- Full local `just ci` passes on the cleaned branch.
- MeshLLM host-runtime suite: 1,568 passed, 0 failed; strict Clippy
passes.
- Buzz desktop Tauri suite with `mesh-llm`: 1,721 passed, 0 failed;
strict feature Clippy passes.
- Playwright covers client-to-share using the saved local model and no
destructive stop.
- Packaged two-machine testing proved single-model routing, dual-model
collective routing, tool-markup fallback, and runtime reuse.
- Packaged client-only recheck routed a real Mini Buzz turn through M5
while Mini stayed `is_client=true`, `is_host=false`, hosted no models,
and created no Gemma cache.
Builds on the recovery work merged in #2823; this PR does not duplicate
it.

## What
One-line default change: `DEFAULT_AGENT_PARALLELISM` 24 → 10
(`desktop/src-tauri/src/managed_agents/types.rs`), requested by Tyler in
[buzz-generic-acp-harnesses](buzz://message?channel=d6d84fdc-47fe-4e41-acf5-a08a4a013e6b&id=a047ead3a34ba804c376bf79f29e355d304162a88c7b2a7121e092547c572022).
## Why
Each unit of parallelism is a **full agent subprocess** per agent ×
community pair, spawned eagerly and serially at create/start before the
harness connects to the relay:
- At 24, a desktop with a few dozen agent×community pairs carries >1,000
potential idle subprocesses.
- Slow-starting harnesses (OpenClaw measured at 4–10s per worker) take
minutes to create, and messages sent during that window can be
permanently missed (the startup watermark is captured only after eager
pool init).
- Parallelism is per-channel concurrency — a channel never uses more
than one worker — so 10 still covers concurrent-channel fan-out for
typical agents.
Context: verified RCA + live 1-worker/3-mention experiment in the same
thread. Demand-driven pool growth (seed 1, grow on contention up to the
cap) is agreed as a follow-up; this is the interim risk reduction.
## Scope / blast radius
- Existing agent records keep their persisted `parallelism` value — only
new records and unset defaults change.
- Per-agent override unchanged (1..=32 via agent editor /
`BUZZ_ACP_AGENTS`).
- Readers of the constant (`team_snapshot`, `personas/snapshot/import`,
`commands/agents` mint path) all take the new default transitively; no
other code pins 24.
- `activeAgentTurnsStore.test.mjs` comments updated so the 24-turn
eviction case is framed against the harness cap (32) instead of the
default — coverage unchanged, no assertion touched.
## Verification
At 63bb0c1c4, same shell: desktop Rust `cargo test --lib` 1693/0 (14
ignored) · JS suite 3523/3523 · tsc clean · biome clean on touched file
· cargo fmt clean.

## Summary
Introduces a single effective-config resolver that makes agent
definitions authoritative for model, provider, system prompt, and
relay-mesh routing on linked instances. Stale materialized record bytes
are never consulted at spawn, deploy, readiness, hash, card summary, or
mesh preflight.
**Resolution semantics (field-specific):**
- **model/provider (linked):** definition → global. `None` = inherit
global default. Record value never consulted.
- **model/provider (definition-less):** instance → global.
- **system_prompt (linked):** strictly from definition; blank = no
prompt. No global tier for prompt.
- **system_prompt (definition-less):** from the instance.
- **relay-mesh preflight (both):** driven by the same
`resolve_effective_config` resolution spawn's mesh env consults. For a
linked instance the record's own `provider`/`model`/`relay_mesh` bytes
are never consulted; for a definition-less instance with no provider of
its own, the legacy marker and env preset are the last fallback (see
below).
- **Orphaned (linked record, definition missing):** spawn, deploy, and
mesh preflight blocked with actionable user-facing error.
**Changes:**
- New `effective_config` resolver module with `ConfigSource` metadata
(`definition`, `global`, `instance_legacy`)
- All consumers routed through the single resolver: local spawn, deploy,
readiness, spawn hash, card summary, relay-mesh preflight (interactive
start and restore-on-launch)
- `apply_persona_snapshot` no longer preserves stale record
model/provider when definition is blank
- Backend `update_managed_agent` blocks model/provider/prompt writes for
linked records
- Frontend omits model/provider/systemPrompt submission for linked
instances; system prompt override hidden
- `model_source` field added to `ManagedAgentSummary` so card labels
distinguish inherited (`Default model (X)`) from explicit
- Spawn hash now digests resolved model/provider (not raw record fields)
so global default changes trip the restart badge even for runtimes
without `model_env_var`
- Orphan spawn/deploy/mesh-preflight blocked with jargon-free error
("This agent's configuration is missing — it may still be syncing or was
deleted on another device")
- `EffectiveAgentConfig::relay_mesh_model_id()` and
`resolve_effective_relay_mesh_model_id()` added; both mesh preflights
(`start_local_agent_with_preflight`, `restore_managed_agents_on_launch`)
call this instead of the deleted
`relay_mesh_config`/`relay_mesh_model_id` record-byte sniffs
- Legacy relay-mesh records keep their mesh routing. Two shipped
generations predate `provider: "relay-mesh"` and are never rewritten on
load: the typed `relay_mesh` marker (added when `ManagedAgentRecord` had
no `provider` field), and before it the mesh preset written directly
into `env_vars`. `resolve_definition_less` falls back to the marker,
then to the env preset, so these records still resolve to mesh instead
of silently misrouting to an unrelated provider while their stale env
bytes reach the child. The fallback is skipped when the record carries
an explicit `provider` — that states current intent, including a switch
away from mesh — and `resolve_linked` has no legacy fallback at all
- The env discriminator accepts both spellings of the two sentinels
renamed in the Jun-11 window without a record migration: the provider
env key (`BUZZ_AGENT_PROVIDER`, previously `SPROUT_AGENT_PROVIDER`) and
the api-key value (`buzz-mesh-local`, previously `sprout-mesh-local`).
Each is independent, since a record can straddle the window; the current
provider-key spelling wins when both are present
- Dead `persona_field_with_record_fallback` and wrapper
`persona_snapshot_with_agent_config_fallback` deleted; callers use
`persona_snapshot` directly
- New resolver/deploy/hash/write-guard/mesh-preflight tests, including
switch-away and global-inheritance regressions for both mesh preflight
call sites, per-class legacy-mesh resolution (typed marker and env
preset, in every rename-window spelling combination), and the paired
assertions that a linked instance's legacy mesh bytes stay inert

Ubuntu Doctor reports `Install failed at verify: The installer finished,
but Buzz still could not use claude-code (observed: CLI missing)` while
the `cli` step shows success. The `cli` step is lying.
## The masking
Every CLI install command is a pipe — `curl -fsSL
https://claude.ai/install.sh | bash`
(`managed_agents/discovery.rs:109`), `… | sh` for Codex (`:141`), `… |
CONFIGURE=false bash` for Goose (`:75`). `install_shell_command` ran
them through `bash -l -c` with no `pipefail`, so the pipeline's exit
status was the **right-hand** side's. A `curl` that fails — or that
isn't on the child's PATH at all — feeds `bash` an empty stdin, and
`bash` with nothing to run exits 0:
```
$ /bin/bash -l -c 'curl -fsSL https://nonexistent.invalid/x.sh | bash'; echo $?
curl: (6) Could not resolve host: nonexistent.invalid
0
$ PATH=/tmp/empty /bin/bash -l -c 'curl -fsSL https://claude.ai/install.sh | bash'; echo $?
bash: line 1: curl: command not found
0
```
`run_install_command` records exit 0 as `success: true`, the adapter
step then installs fine (it uses Buzz's own bundled Node, no system PATH
needed), and `post_install_verification` correctly reports the CLI is
absent. The user is handed a `verify` riddle instead of curl's error,
which is why diagnosing this required three rounds of guessing.
Install commands now run under `set -o pipefail`, so the left-hand
side's failure is the step's failure and `InstallStepResult.stderr`
carries the vendor's own message. `SHELLOPTS` is not exported by either
shell, so the piped-to vendor script still runs with its default
options. The Windows PowerShell install path
(`install_powershell_command`) bypasses this shell and is untouched.
## The PATH collapse it was hiding
`install_shell_command` composes the child's PATH and calls
`cmd.env("PATH", …)`, which **replaces** rather than extends.
`should_use_inherited` was `is_windows && !had_shell_path &&
has_local_context`, so on Unix the inherited process PATH was never
appended. When `login_shell_path()` returns `None` — a login shell that
exits non-zero or prints nothing, which a GUI-launched process can
easily hit via `~/.profile` — the child's entire PATH becomes Buzz's two
managed Node dirs. There is no `curl`, `sh`, `sha256sum`, or `tar` in
either, so every curl-pipe install fails, and before this PR it failed
invisibly.
The `is_windows` requirement is dropped: the inherited PATH is the floor
whenever no login-shell PATH was obtained, on every OS. Both existing
suppressions are kept — a login-shell PATH present still suppresses it
(no doubling), and no home/exe context still suppresses it (never
manufacture a PATH from ambient state alone). Inherited entries stay
**last**, so managed dirs keep precedence.
The other caller, `build_augmented_path` (`runtime/path.rs:148`, feeding
agent spawns and CLI probes), reads correctly under the new rule for the
same reason: it only gains the inherited PATH in the case where it would
otherwise hand a child a PATH with no native entries. When a login-shell
PATH exists — the normal case on macOS and Linux — its output is
unchanged, which `unix_shell_path_suppresses_inherited_fallback` pins.
## Scope
This fixes the reporting defect and the PATH floor. The specific
environment failure on the affected Ubuntu box is still being diagnosed
and is deliberately not addressed here; the point of this change is that
the next attempt produces the real error instead of a `verify` riddle.
One interaction worth noting: `install_failure_is_retryable` retries any
failure that carries an exit code, so a pipefail-surfaced curl failure
now gets 3 attempts with backoff — correct for transient network blips,
and harmless for hard failures.
`desktop/scripts/check-file-sizes.mjs` ratchets the `agent_discovery.rs`
ceiling 1836 → 1895 for the added tests.

## Summary
- split the managed-agent runtime warehouse into cohesive modules for
process ownership/termination, orphan sweeping, dead-instance reaping,
lifecycle synchronization, and runtime metadata
- preserve the existing `runtime` API through narrow re-exports; helper
bodies and platform `cfg` branches are unchanged apart from
module-qualified visibility
- reduce `runtime.rs` from 2,220 lines on `main` to 908 lines and remove
its temporary file-size override, restoring the standard 1,000-line
ceiling
## Why
`main` failed after stale successful PR checks allowed independent
growth to combine above `runtime.rs`'s 2,216-line override. The earlier
fix in #2974 extracted only 55 lines and left the monolith on a special
ratchet. This replacement includes that extraction but establishes
responsibility boundaries and removes the exception entirely.
## Module boundaries
- `process.rs` — process identity, ownership markers, receipt
validation, and termination primitives
- `orphan_sweep.rs` — same-instance orphan discovery and cleanup
- `instance_reaper.rs` — foreign/dead desktop instance detection and
agent reaping
- `lifecycle.rs` — tracked runtime synchronization and stale record
cleanup
- `metadata.rs` — model/provider metadata resolution
- `runtime.rs` — summary/config/spawn orchestration and composition
## Validation
At `a824fda31eff6ecc0d39ca1b8ea5602a108897e6`:

## Why
The Codex adapter install-plan test depended on the process-global
login-shell PATH cache, making it flaky under concurrent or loaded CI
runs.
## What
- Thread an explicit probe PATH through adapter install planning
- Use a controlled PATH in Codex install-plan tests
- Update the existing desktop file-size allowance for the focused seam
## Risk Assessment
Low — production behavior keeps using the same augmented PATH; only
dependency injection and deterministic tests change.

## Why
Installing the Codex, Claude, or Goose desktop app does not install the
command-line harness Buzz needs. The current UI makes that distinction
unclear, links some missing-CLI states to adapter documentation, and can
report a successful install from the installer exit code even when
runtime discovery still fails. On Windows, Buzz also invokes Goose's
Bash installer, which writes the executable somewhere Buzz does not
discover.
## What
- distinguish missing vendor CLIs from missing or outdated ACP adapters
in runtime metadata and UI guidance
- link Codex, Claude Code, and Goose missing-CLI states to their
official CLI installation documentation
- explain in Settings, onboarding, and agent configuration that the
desktop app alone is not sufficient
- use Goose's official PowerShell installer on Windows
- refresh PATH and rediscover the requested runtime after installation,
keeping the control retryable if the runtime is still unavailable
- add Rust and Playwright regression coverage for Windows installer
selection, CLI/adapter guidance, false-success prevention, verified
installs, and onboarding copy
## Risk Assessment
Medium. This changes desktop onboarding and runtime installation
behavior. Successful installs now require the runtime catalog to verify
availability; previously hidden discovery failures will surface as
actionable errors instead of a false success state.

On Windows, the model dropdown never populates for CLI harnesses (Claude
Code, Codex) while the same flow works on macOS.
Model discovery spawns `buzz-acp models` with `PATH` taken from
`login_shell_path()` — which by design always returns `None` on Windows
(Git Bash's POSIX-shaped PATH would poison native children). The
discovery child therefore ran with only the raw inherited process PATH,
missing the Buzz-managed Node/npm directories and exe-parent sidecar
dir, so the ACP adapter's `.cmd` shims failed to resolve `node` and
discovery returned nothing. macOS worked only because a login-shell PATH
exists there.
The fix reuses the existing `augmented_path()` helper (already used by
CLI login probes and auth commands, built on the same
`build_augmented_path` kernel as the real agent spawn), so model
discovery resolves the identical toolchain the agent will actually run
with. `login_shell_path()` remains the login-shell component inside that
composition — on macOS the composed PATH is a superset of the previous
value.

## Why
On macOS, GUI apps launched from Finder/Spotlight/Dock inherit a minimal PATH from launchd (`/usr/bin:/bin:/usr/sbin:/sbin`). The `discover_provider_candidates()` function in `backend.rs` only scanned this process PATH when looking for `buzz-backend-*` executables. As a result, backend providers (like `buzz-backend-blox`) were never found, and the "Run on" dropdown in Agent Settings was hidden — even though the binary existed both in the app bundle (`Contents/MacOS/`) and in `~/.local/bin`.
## What
Augment the search directories in `discover_provider_candidates()` with:
1. **exe parent dir** (`Contents/MacOS/` in a `.app` bundle) — so bundled providers are always found regardless of how the desktop was launched
2. **`~/.local/bin`** — the conventional location for user-installed provider binaries (symlinks created by install scripts)
Both directories are only added if not already present in PATH (deduplication). The exe parent dir is prepended (highest priority for bundled providers); `~/.local/bin` is appended.
## Verification
- `cargo check --lib` passes
- All 17 `managed_agents::backend` unit tests pass
- Pre-push hook `desktop-tauri-test` passes (38s)
## References
Root cause confirmed by inspecting the running `buzz-desktop` process environment:
```
$ ps eww <pid> | grep PATH
PATH=/usr/bin:/bin:/usr/sbin:/sbin
```
