Supersession (newer navigation, path editing, closing, unmount) now
aborts the in-flight listing's request instead of only discarding its
result: the browser mints an AbortController per listing, the signal
rides the workspace face (IWorkspaces.listDirectory gains an optional
signal) onto the fetch carrier, and the Host scan stops with it (817's
cancellation chain). apps/cli keeps both picker packages as dependencies
so the documented one-row cordis.yml swap to the native backend resolves
at boot.
One list call now materializes at most maxEntries child rows (config,
default 1000 - GitHub's web-UI directory-listing bound). Candidates sort
before probing so a cut level keeps the name-sorted head and symlink
probing stops with the bound, and DirectoryListing carries a required
truncated flag on the seam and the wire so clients can state
incompleteness instead of silently missing tail entries.
Union resolutions throughout — the fixture serves both the goal and plan
projection units (catalog gains /goal beside /plan; the retired
goal-fixture sample command yields to the real goal mirror), the mux
baseline spec expects all four unit frames, and the tsconfig paths /
Model Experience allowlist carry both domains' outlets.
master's new ctx.workspaces contract face (IWorkspaces + TestWorkspaces
double) predates this stack's listDirectory/createDirectory; widening the
face is the explicit act of letting the browse flow drive them, and the
double records/stubs them like its siblings.
Feature packages now reach these domains through interface types only:
ISession/SessionFace (identity + prompt/cancel/loadOlder + the useSession
snapshot source), ISessions, IWorkspaces, ILayout, IConversation, and the
existing SlashServiceContract now actually mounted on Context.slash. The
concrete services implement their face; wire-pump and assembly entry
points stay on the classes. The provide-channel materialization and
current-projection logic moves into SessionProvideChannel so the
production service and the client test runtime share one implementation.
The workspaces service consumes sessions through the narrow SessionsPort.
The summary blank bit switches from log emptiness to the absence of any
turn/start: standalone plugin events — command lifecycle records,
plan/mode, session titles, goal metadata — no longer surface a fresh
session in lists or steal the New Session view. Running /plan (or /goal)
on a blank session keeps it blank and reusable; the first accepted
prompt's turn clears it. Both carriers share one predicate (summarize +
the host/session-added frame); the cold path keeps its constant false
with the index-read rationale; the client mirror already flips only on
prompt acceptance and needed no change.
Review finding (PR #791): the column carried bare values (no seq), so the
client could not seed its value store without risking a stale list block
outranking newer push frames — and nothing consumed the column at all,
leaving cold titles absent after a restart. SessionSummary.projections is
now the same SessionProjectionsBlock as the history tail (values +
asOfSeq; attached rows cut the live registry, cold rows serve the cache's
identity-checked cachedSnapshot whose asOfSeq is the lowest served-row
watermark). SessionManager.refreshList seeds each row's block into the
per-session projection store via per-key apply — partial-baseline
semantics: an absent key never clears, and higher-seq-wins keeps stale
list blocks beneath push frames and tail baselines — so cold titles
surface in the sidebar without opening a session.
ui-workspace's two trigger surfaces each declare a single-kind directory-flow
hole (conversation.hero.workspace.directoryFlow / sidebar.workspaces.directoryFlow,
same owner contract) and keep only the trigger and the adoption: the Open-local-
folder entry renders while the surface's hole is occupied, and the occupant
reports one picked path per open through the hole's owner conversation
(open/busy/onPicked/onCancel/onError).
directory-picker-native becomes dual-face: its browser half fills both holes
with a renderless occupant driving host.pickDirectory, so the cordis.yml row
that mounts the backend also composes the client interaction — a mismatch is
impossible and a second flow package fails at client load.
With composition wiring both sides, the host.describe.directoryPicker
advertisement and the client's kind branching lose their last consumer:
the field, WorkspacesService.directoryPickerKind(), the DirectoryPickerKind
wire type, and the picker's per-open describe read are deleted. The connection
fixture now serves a deterministic pickDirectory path so the keyless snapshot
drives the full pick-then-adopt flow. ui-workspace's hand-rolled declaration
deferral is replaced by the deferRegistration helper it duplicated.
The browse interaction also presents a dialog (the in-app modal), so 'dialog'
failed to discriminate the two capability kinds; 'native' names where the
chooser runs. Package directory-picker-dialog -> directory-picker-native, kind
'dialog' -> 'native', with every seam/gateway/client/doc reference updated and
the seam Agent Note's naming rationale rewritten to match.
Six mutation RPCs (create/edit/pause/resume/complete/clear) move into
dsh-host-apiproxy (the PR's host/runtime carrier is gone): goalService()
resolves ctx.get('goals') with a loud absence error, mutateGoal() resolves
the session's agent (agentFor, the command.* implicit-resume precedent) and
acknowledges with the new CAS ref only. GoalError codes ride err.details.
goal.get and the wire GoalView/goalViewSchema are gone: the read side is the
'goal' session projection (whole values on the history tail page and
session/projection frames), so responses never feed client state — the rule
whose absence forced the original PR's write-revision fences.
Conflict rulings follow the projection-reattach plan:
- host/runtime package (deleted on master): take master; the PR's boot
composition moves to the cordis.yml roster and its goals handlers will be
re-landed in dsh-host-apiproxy; the session.prompt slash interception and
its spec are dropped entirely (superseded by command.execute + command/run
logging).
- client core (rewritten on master): take master; the PR's Session goal
fields/methods, ConversationSnapshot.goal, goalActions injection, and the
hard-mounted GoalBar are all superseded by the 'goal' session projection
(useProjection) and will return as the ui-goal plugin.
- wire contract: union of master's workspace/command/skill domains and the
PR's goal domain, minus goal.get (the read side is the projection block +
session/projection frames; six mutation RPCs stay).
- GoalBar component and spec leave ui-conversation (they re-land in the new
ui-goal package); IconSparkle16 stays in ui-conversation chat.
- The web-slash-command-dispatch note documents the dropped interception and
is removed; the goal-bar note will be rewritten for the projection model.
- pnpm-lock.yaml taken from master (reinstall recomputes).
The web GUI's folder picking was hardwired to one interaction: a native
OS chooser compiled into the gateway, unusable for remote deployments
and swappable only by editing apiproxy source.
Directory picking becomes a three-package capability seam in
packages/host: ctx.directoryPicker returns a discriminated capability —
dialog (the extracted native chooser; host-display only) or browse
(new: one-level listing + child creation over Node stdlib, hidden flags
host-stamped, symlinks followed, ancestry crumbs; remote-capable). The
gateway injects the seam, advertises the kind via
host.describe.directoryPicker, serves host.listDirectory /
host.createDirectory under browse, and answers
directory-picker-unavailable across kinds. cordis.yml is the swap
point; apps/cli keeps dialog mounted, so behavior is unchanged until
the in-app browser PR flips the default. The connection fixture serves
a deterministic browse tree; WorkspacesService gains the browse calls
the browser UI will drive. Decision record:
.agents/notes/implemented/architecture/2026-07-28-directory-picker-capability-seam.md
Review follow-ups: the three new notify loops (currentProvideInfo
subscribers, ui-skill lexicon listeners, late-registration controller
setup) now contain per-callback failures so one faulty consumer cannot
starve the rest, abort the list projection pass, or poison the source
roster with no disposer; controller lexicon polling drops a throwing
source with a console record like the candidate path. The ui-slash
README (both languages) now states the late-registration warm and the
subscribeLexicon contract, and the scenario suite drives a typed /name
token gaining its decoration when the roll settles with no further
input.
provideInfo(id)/maybeProvideInfo(id) lost their last external caller
when the renderer host switched to the currentProvideInfo observable;
both become private (tests assert through the public projection). The
reprojection method's name now says what it does — re-derive and
publish on change — and matches the field family it maintains.
