Six review findings on the select surface, all reachable from the wire:
**Resume read the header, not the log.** The switch was recorded as
`agent-preset/selected` and every projection resolved from it, but `agentFor`
still composed from `inspected.meta.agentPreset` — the value written once at
creation. A blank session that switched and then ran turns came back after a
restart under the ORIGINAL preset, restoring that history under the tool set it
was not produced with, which is the mismatch this feature exists to prevent.
`inspected` already carries the events.
**Cold summaries dropped the preset entirely.** `summarizeCold` hand-copied
three header fields and omitted the fourth, so a restored session reported no
preset and the picker showed the deployment default. It now uses the same
projection the attached path does.
**`select` had no gate.** Two concurrent selects both passed the blank check;
the second `unmountPresetFor` then found no record, because the first had
already removed it, and both mounts installed into one agent layer. Selects on
one session now queue, and the blank check is re-read inside the queue. This is
not turn admission — a `session.prompt` racing a switch is the agent loop's to
reserve — but it closes the select-versus-select tear-down.
**A same-id restore was skipped.** The roster is a live directory, so "the same
inputs that worked a moment ago" does not hold: a changed file is exactly how a
same-id reselect fails, and skipping the restore left the agent with no
composition at all.
**`writable` was dead state**, initialized true and never set, so the row could
never disable. It now carries `settings.describe`'s bit — a browser that may
not write settings sees the current default and no control, rather than one
whose write answers `settings-not-exposed`.
**`list` was documented as id-ordered.** It is root-precedence order with each
root's own presets sorted, first root to supply an id winning.
Copying is already its own action, offered on the row being copied, so the two
routes now arrive at the same editor by whichever one the author chose. **New
preset** starting from some preset nobody named put a composition in the editor
that the author had to recognise as unwanted before deleting it — and the
preset it copied was the deployment default, which is the one least likely to
be what someone reaching for "new" wanted.
A blank draft has no source, so it names none and makes no read: the editor's
"copied from" line and header clause appear only when there is a source.
Authoring writes a FILE, not a settings field, so nothing on the wire announces
it — `settings/changed` covers the default moving, never the directory. The
chip therefore kept the roster it read when it first mounted, and a preset
authored to be used was missing from the one screen that starts sessions.
The page that changes the directory now says so, and every surface reading the
same roster re-reads it. The chip subscribes rather than being reached from the
outer scope, because it is registered later, under `conversation`/`sessions`.
The General row and the preset page already re-read on `settings/changed`, but
the hero chip did not — so changing the default and starting a session without
reloading composed the previous default. That is the one session the setting
claims to govern ("对此后新建的会话生效"), and the chip is what decides it.
A staged pick still wins: `load()` prefers the stage over the refreshed
fallback, so a refresh never overwrites a choice the user just made.
The preference row rendered `option.id` while every other surface — the
new-session chip, the session header label, the preset cards — renders the
metadata name. So the same roster read `标准模式` on one screen and `standard`
on the next, and the id is addressing, not a label. A preset that names itself
nothing still falls back to its id, which is then all there is to say about it.
The row's Chinese copy also still ended on the English word: the section is
`Agent 预设`, so the sentence about a running session keeping its composition
says 预设 too.
`ui-question`'s node half called `ctx.tools.register` on the host context.
`ScopedLayers.merge()` combines the global layer with the agent's exact-scope
layer, and an unscoped registration lands in the global one — so the tool
reached every agent no matter which preset composed it. `core-web`, sold as a
two-tool benchmark surface, really presented three.
Rendering a question is a host UI capability; having the tool is an agent
capability, and only a preset decides that. The node half is now empty and the
`tool-ask-user` row moved into the preset that wants it. The TUI keeps its own
row, having no presets.
The composition tests now assert the global tool layer is EMPTY, which is the
invariant that would have caught this: any tool outside a preset reaches every
agent. The browser lane's composition, seeded-history, and hermetic-skill
assertions address their registries through a composed agent for the same
reason — those services are per session now, and the host cannot resolve an
`isolate` realm by name.
The browser e2e lane had been failing wholesale since this stack moved the
agent plane into presets, and nothing caught it: 34 of 48 files. Two of the
causes are product defects, not test breakage.
`bashEnv` goes back to the host plane. `apps/cli/src/web.ts` injects it to
publish `DSH_WEB_URL`/`DSH_WEB_MODE`, so the earlier note that "nothing outside
the agent plane injects bashEnv" was simply wrong — behind a preset's `shell`
realm those variables reached no shell at all, and a `dsh web` agent could not
find the address of its own interface. This is the same criterion that returned
`subagents`: a host row that injects a service resolves before any session
exists and has no agent to key by, so the service is host-plane. `tool-bash`
consumes the host registry from inside the preset, which works because an
agent context chains to the host; only the reverse is invisible.
`tool-subagent-report` goes back with it. It is not a tool this agent calls: it
registers a continuable SETUP on the host `subagents` singleton, and that list
is not scope-aware. One copy per mounted preset meant every child was handed
`report` once per live session, so the second registration threw and a cold
subagent resume failed with `subagent-not-resumable` — a diagnostic three
layers removed from the cause.
The lane's own composition facts follow. Skill roots resolve inside a preset
now, a subtree include patches cannot reach, so the scaffold pins the roots'
documented environment fallback for its whole lifetime rather than for the boot
— presets mount per session. Without it the developer's real `~/.dsh/skills`
enters replay requests and goldens while CI sees none. The `apps/cli`
composition test pins `storage-json` for the same reason: unpinned it wrote,
and then read back, the developer's own `~/.dsh/storages/`.
Three tests now address through an agent what they used to read off the root
context, because that is where the thing lives: the tool catalog, the skill
registry, and the token meter. The seeded-history projection baseline asserts
the opposite of what it did — a detached session yields a preset-plane
projection only from a durable checkpoint written while it was live, and this
seed was written straight to persistence and never ran.
Goldens re-recorded for the hero's preset chip and the settings nav entry.
Sections differ by hundreds of pixels — a short preferences list against
the composition editor — and the 600px panel served both badly: the
list left a wide empty band, the editor cramped a YAML file into a
16-row box with dead space under it.
The panel is now `min(800px, 100vh - 48px)`: one height for every
section, whatever does not fit scrolls where it already did. The
composition editor takes the column's full height rather than a fixed
row count, so the extra space reaches the text instead of the gap.
Refresh the settings goldens the preset section's nav entry had made
stale.
The composer seat spent nearly all its life disabled: a session's
composition is fixed once a turn has run. Move the choice to the
new-session screen beside the workspace picker, where it still works,
and let the session header report what a running session runs.
The hero pick is staged rather than applied — that screen precedes the
session it belongs to. It lands when a session becomes current and is
still blank, which covers both the session a workspace connect creates
and the blank one it reuses; riding `sessions.create` would miss the
second. It is spent on first use, matching the workspace picker.
Fix the durability the header field claimed but never had: `agentPreset`
was declared on `SessionHeader` and dropped by the JSONL header line, the
SQLite sessions row, the derived query index, and the cold list
projection, so every resumed session came back composed from nothing.
Add the web e2e lane that would have caught it — the one lane that mounts
the shipped roster, which needed `cordis:group` in the scaffold's Loader
builtins, as `mountRootInclude` already registers.
A shipped preset has nothing to commit or abandon, and the back link above
already leaves the screen; a lone Close button below the composition was a
second way out of the same place. The action row now renders only when the
draft is writable, where Cancel and Save are both real choices.
The composition label named `cordis.yml`; the file a preset actually holds
is `agent.cordis.yml`.
The picker listed presets alphabetically by id, so the shipped set read
cordis, minimal, standard — reverse order of capability. A preset may now
declare `order` in its metadata; the shipped three declare 1/2/3 and read
standard, minimal, cordis. A preset that declares none sorts behind those
that do, then by id, so authored presets stay stable.
Editing had nowhere good to live. Inside a card it was squeezed into a
~268px column; hanging off the end of the grid it was orphaned from the card
it edits. It now replaces the list: a back link, what is being edited, and
the form at full width. One thing on screen at a time, which is what the
form's height wanted all along.
Cards in different grid rows sized independently, so a short description made
a short card. `grid-auto-rows: 1fr` makes every row the same height.
The trust badge lost its pill when the card CSS was rewritten, and `In use`
never had one; both are tags now. Icon labels moved from `title` to a drawn
tooltip — the native one waits about a second, which reads as nothing
happening.
Four changes to the Agent 预设 section, all from the same reading: choosing
a preset is the common act and everything else is occasional.
Picking is now clicking the card rather than hunting a small "Set as
default" button. The card body is the button; the action row sits outside it
because nesting buttons is invalid and those actions operate ON a card
rather than select it. The body's accessible name is set explicitly —
otherwise it is the whole card read aloud, title through id.
Actions are icon-only with their label on hover and on `aria-label`, so four
controls stop competing with the content for attention.
Built-in and custom presets are separated under headings, and the trust
badge moved up beside the title where it qualifies the name. A group with no
members renders no heading.
`Local` reads as a location; these are the user's own, so the badge and the
heading both say `Custom` / 自定义.
`core-web` said neither of the things that matter about it. The `-web`
suffix is a leftover from the whole-process `core-web.cordis.yml` overlay,
and presets are per-session and not web-specific. `core` reads as "the
foundational one" when it is in fact the one with the fewest capabilities.
`minimal` says what it is and orders the shipped set legibly by capability:
minimal, standard, cordis.
Breaking: a session created under `core-web` records that id in its header
and will fail to resolve it on resume. Nothing outside this repository has
shipped, so no migration path is offered.
The identically named `config/core-web.cordis.yml` — the legacy
whole-process overlay behind the web snapshot test — is a different thing
and keeps its name.
A picker showed directory names, so the settings page could only ever list
`standard` / `core-web` / `cordis` and hope the reader knew what they meant.
A preset may now publish display text in an optional `preset.yml` beside
its composition, and the section renders cards — name, description, and the
one in use — instead of rows.
The file carries display text ONLY. `id` is the directory name and `trust`
comes from the root a preset was discovered under, so neither is writable
there: otherwise a locally authored preset could name itself into the
shipped set. It is a separate file because a composition is a top-level list
of plugin rows — YAML cannot carry sibling keys beside it, and a fake
metadata row would hand the Loader something to load.
Every read failure degrades to no metadata; absent, malformed, wrongly
typed, and blank all mean the same thing and the picker falls back to the
id. Presentation is not capability: a preset whose name is broken still
mounts.
The editor gained name and description fields above the YAML, and clearing
both removes the file rather than storing a blank name.
The Chinese copy was mixed: the nav read 智能体 while every other string kept
`preset` untranslated (本会话的 agent preset, 新建 preset, preset 名称).
It is now one register throughout — Agent stays, preset becomes 预设, the
standard Chinese UI word for a named, switchable configuration bundle, which
is what a preset is when a session picks one.
UI copy only. The docs keep `agent preset` as the technical term for the
composition and the `agent-presets` plugin.
Three fixes to the settings surface.
The default never reached settings.yaml. The api-proxy keeps an explicit
allowlist of settings namespaces it exposes to configuration clients, and
`agent-presets` was never added — so both pickers moved and then silently
forgot, which is worse than refusing the control. The host seam was fine all
along; only the wire boundary refused. The regression test fails with the
namespace removed.
The nav row showed the fallback gear and read `Agent preset` in Chinese,
matching neither sibling (通用设置 / 模型). It is now 智能体 with the think
glyph, the only unused icon in the set whose semantics point at the agent
rather than at tuning sliders (Personalization is already the workspace
browser's filter control).
`ui-question`'s node half called `ctx.tools.register` on the host context.
`ScopedLayers.merge()` combines the global layer with the agent's exact-scope
layer, and an unscoped registration lands in the global one — so the tool
reached every agent no matter which preset composed it. `core-web`, sold as
a two-tool benchmark surface, really presented three, and a locally authored
`bash-only` preset presented two.
Rendering a question is a host UI capability; having the tool is an agent
capability, and only a preset decides that. The node half is now empty and
the `tool-ask-user` row moved into the presets that want it. The TUI keeps
its own row, having no presets.
The web composition test now asserts the global tool layer is EMPTY, which
is the invariant that would have caught this: any tool outside a preset
reaches every agent.
A composition is a file, but "edit it on the filesystem" is not a browser
affordance. The roster gains `read`/`write`/`remove` beside `select`, and
the browser gains a settings section over them: the presets as rows, one
composition open in a YAML editor at a time, and per-row default, duplicate,
and delete.
All four authoring methods are loopback-pinned. A composition names the
plugins a session runs, so reading one is reconnaissance, writing one is
arbitrary capability, and selecting one can move a session onto a preset
that edits the live runtime. `agentPreset.list` deliberately stays ordinary
and now reports `authorable`, so a surface knows whether creating is
possible at all rather than offering a button whose save always fails.
Authoring starts by duplicating: a shipped preset opens read-only because
the deployment's copy is what a broken local one is compared against. Ids
are contained before they become directory names, and the text is parsed
with the loader's own schema, so a save cannot leave a file no session
could load.
Fixes a defect the real-composition test found: a preset written under the
user's home could never mount, because the loader resolves a row against the
composition's own directory and Node's `node_modules` walk from there never
reaches the installed harness. The mount now records the host base and sends
bare specifiers there, leaving relative paths resolving from the preset.
Also closes the coverage the earlier surfaces in this stack shipped without —
the General row, the composer seat, and the plugin halves now have tests.
The creation header names the preset a session STARTED with and is frozen,
which is correct — it is a creation fact. Switching is legal only while a
session is blank, and that looked like enough: no history exists yet.
It is not, because the switch's effect outlives the blank window. The user
switches, then sends the first message; every turn from there runs under the
new composition while the header still names the old one. The session is
then locked around a misrecorded preset, and resume reads the header to
rebuild it — composing one preset's tools over a history another produced,
which is exactly the replay the blank-only lock exists to prevent, reached
by another route. A picker showed `standard` for a session running
`core-web`.
A switch is now an `agent-preset/selected` event appended after the swap
commits, and `resolveSessionPreset()` (last selection, else the header) is
what every reconstruction reads: the summary, resume, the conflict guard,
and the fork introduced one layer down.
A seat in the composer tool row, left of the model select, showing the preset
THIS session runs — its own recorded one, not the deployment default, because a
resumed session runs what it was created with. `SessionSummary` carries
`agentPreset` for that, alongside `cwd` and `origin`.
The switch exists only while the conversation has not started. After the first
turn the seat becomes a plain label rather than a disabled menu: a greyed
control reads as "temporarily unavailable", when in fact the choice is gone for
good. The seat never asks in that state, and the host refuses independently
with `agent-preset-locked`, so a stale client cannot slip one past it.
A rejected switch restores the previous value and surfaces the host's message
rather than leaving the seat showing something the session is not running.
`agentPreset.select` recomposes one session's agent from a different preset.
It is allowed only while the session is blank — once a turn has run, that
history was produced under the preset's tools and swapping them would strand
logged tool calls, so the attempt answers `agent-preset-locked`.
The agent and the session survive; only the preset subtree is swapped. That
was forced by what the host actually owns: api-proxy discards the `AgentHandle`
it creates, and there is no delete RPC, so neither disposing nor recreating the
session was available. Swapping the subtree is also the better answer — the
session id, its workspace attachment, and its projections all stay put.
`recompose` is unmount-then-mount because two compositions cannot coexist: both
would register the same tool names into one layer. So it resolves the new
preset BEFORE tearing anything down (an unknown id is a no-op) and restores
the previous composition when the new one fails to mount, rather than leaving
the agent with no tools at all. Both paths are pinned by test.
Also restores the English half of the `agentPreset.list` README paragraph,
which was lost before the previous commit — and `verify-translation-pairing
--write` recorded the pair as consistent anyway, because it records whatever
state it finds rather than checking the two sides say the same thing.
One settings row picking which preset new sessions are composed from.
It is deliberately a new-session preference, not a live switch: a session's
preset is fixed at creation and the host refuses to adopt an existing session
under a different one, so the row says "applies to sessions you start from now
on" rather than implying it can retune a running agent.
Options and the current value come from one `agentPreset.list` call — the
roster already reports which id an unspecified session gets, so the row needs
no settings-schema introspection, unlike the permission row it is modelled on.
The write targets only the namespace's `default` field.
The menu marks `user` rows: a locally authored preset is exactly as privileged
as the plugins it names, and presenting it identically to a shipped one would
hide that.
An empty roster reads as `unavailable` and renders nothing, because composing
no presets is a valid deployment rather than a failure — distinct from a
roster call that failed, which surfaces its message.
`agentPreset.list` gives a browser the deployment's roster so it can offer a
choice when starting a session. Each row carries the id, its `trust`, and
whether it is the current default.
`trust` is on the wire deliberately: a `user` preset is exactly as privileged
as the plugins it names, so a surface that offers one alongside a shipped
preset can say which is which rather than presenting both as vetted.
The domain is read-only. A preset is a composition on disk, so authoring one
is a filesystem act rather than an RPC; and a deployment composing no presets
answers with an empty roster rather than an error, because sharing the host
composition is a valid deployment.
The RPC map made every registration site a type error, so the route, the
response-schema table, the service delegate, and the browser fixture are all
wired rather than only the ones I remembered.
knip: ui-settings no longer imports react-dom (the portal moved into
OnboardingSurface), so the react-dom peer/dev dependencies and
@types/react-dom go away with the usage.
Review follow-ups: the Agent Note's Testing section now records the
held-join reload regression scenario this PR adds (both languages,
pairing re-recorded); the e2e hold gates EVERY settings.describe issued
before release instead of only the first, so a future boot-time join
consumer cannot silently collapse the widened window; the sampler's
persistence across later navigations is documented and the vacuity
wording softened to what the hold actually buys (timing independence).
The settings shell painted the onboarding overlay (opaque stage, mask,
#root inert) the moment a step was registered and not locally completed,
while every step still had to load its private join before deciding
whether to show — rendering null could not suppress the shell-owned
chrome. Every reload on the hero therefore flashed a full-screen opaque
layer (white in the light palette) for one settings/credential RPC
round-trip after the session list turned ready.
The chrome now belongs to the step: a new zero-cordis OnboardingSurface
primitive (ui-primitives) renders the body-portaled overlay/mask/stage
verbatim from the former SettingsRoot stylesheet and holds #root inert
for exactly its own lifetime. WelcomeNotice and DeepSeekOnboardingDialog
wrap only their visible branch in it, so their existing null branches
paint and block nothing by construction. SettingsRoot keeps the
coordinator unchanged but renders the elected step bare, and the
settings.onboarding contract now names the surface wrap as the
registrant's obligation.
The onboarding e2e gains a held-join reload scenario pinning that a
configured world never mounts the takeover chrome or inerts the app.
The branch control on user and consumed-steering bubbles could enable
only when a completed turn ended with no node after the message at all,
so readers saw a permanently unavailable control whose tooltip promised
a state it could not reach. An enabled one would mislead anyway: a fork
at a message seq cuts at the containing turn/end and takes the answer
along, the opposite of the branch-to-re-ask reading a control on one's
own bubble suggests.
MessageItem loses its fork props, PendingSteeringBubble loses the
showBranch special case, and messageBranchSeqs narrows to
assistantBranchSeqs: only a completed turn's transcript tail that is
the turn's own content-text assistant may fork. A steered turn keeps
its fork point under the settled answer, because fork is a log-prefix
cut and the steer is model-visible history the child inherits.
Web aria goldens drop the user-bubble disabled-branch row and its
hidden explanation text; the nested-subagent golden also loses the one
enabled user-tail fork handle, a loss the decision note accepts.
