A failed attempt may leave `assistant/chunk` events in its closed step, but it never appends `assistant/message` and never dispatches a tool. A retry closes the failed turn, opens the next numbered turn, reconstructs the request from the durable surface, and produces its own chunks. UIs may render live chunks while a step is open, then mark or clear that transient view when `llm/retry` identifies the failed step or `turn/end` records failure. Web validates the complete retry payload contract, clears the failed partial at `llm/retry`, projects consecutive retry-turn events into one stable row updated to the latest attempt, and derives scheduled, started, or cancelled status from subsequent turn facts. Its countdown anchors the scheduled delay to browser receipt rather than the Host event clock, uses ceiling-rounded seconds with a one-second floor, animates only while unresolved, and keeps exact latest failure details collapsed behind the row. Retry nodes anchor their own trajectory turn even when the failed attempt has no assistant node. Message derivation continues to ignore the failed chunks, and Web applies the same projection during history rebuild so refreshing cannot resurrect discarded partials or duplicate retry rows.
If recovery is exhausted, the final failure is stored once on `turn/end.reason` with the structured facts. If transient recovery continues, `llm/retry` is the durable home for that attempt's failure and delay. No standalone final-error event or response-id vocabulary is added.
If recovery is exhausted, the final failure is stored once on `turn/end.reason` with the structured facts. Web derives one `turn-error` node at that sequence position and renders its display-safe message and optional code inline; AUTH projections replace provider copy that may echo credential fragments with `API key is invalid`, while the raw diagnostic remains in the session log. The same fold runs for live events and history replay. If transient recovery continues, `llm/retry` is the durable home for that attempt's failure and delay, so its failed turn does not also gain a terminal error row. No standalone final-error event or response-id vocabulary is added.

`ctx.agents.create()` and `resume()` build an unpublished session, scope, agent, and driver. They await `setup`, synchronously invoke its optional `AgentSetupCommit`, admit the final session and agent entries, announce them in order, start the loop, and only then return a handle. The commit lets mutable provisioning revalidate at the exact publication boundary after every setup await; a throw rolls the private transaction back before either identity is announced, while revocation after a successful commit is ordinary live teardown.
An optional creation signal cancels work only while create or resume is pending. After the promise resolves, the returned `AgentHandle` owns explicit disposal.
If loading, setup, admission, or publication fails, the private transaction rolls back everything it prepared. Concurrent operations using the same caller-supplied live ID may both reach setup, but final registry entry admits only one; every loser rejects and cleans its private resources.

Setup and its optional publication commit are atomic from an observer's perspective, and teardown preserves local behavior until work stops.

The promise fulfills after the backend crosses its publication boundary, so callers and `subagent/start` observers never need a second `run.started` promise. Provider work that fails before publication rejects `start()`; prompt, turn, cancellation, and infrastructure outcomes after publication settle through `SubagentRun.result` without hiding the child id, as required by the [durable catalog decision](../feature/2026-07-22-durable-subagent-catalog-and-list-agents.md).

Continuable conversations use their separate creation and follow-up operations and have no `SubagentRun`; their manager owns each resident `AgentHandle`.
The service validates provider capabilities and request semantics before calling the provider. A provider rejection cleans any partial resources before the rejection escapes and emits no `subagent/start`/`subagent/end` pair. After fulfillment, the service attaches result observation, emits scoped start, and returns the run. Provider removal prevents later starts but does not revoke a run already accepted by the provider.

- **History = event replay**: one fold (client side); history pagination and live increments share one code path; the server maintains no second materialized-snapshot system. History **page boundaries align to message boundaries** (never cut mid-message; chunks group with their finalized message), and the tail page includes the in-flight partial's chunks.
- **Prompt correlation**: the prompt's rpcId rides MessageSource (`'user-rpc'`) into the `user/message` event; the client uses it to promote the optimistic echo.
- **Reconnect = rebuild**: no resume cursor (`mux`'s `since` signature is a reserved seat, ignored if passed); on disconnect reopen the stream + refetch history; compare `subscribed.lastSeq` with the history tail seq and backfill once if there is a seam.
- **Cold sessions resume implicitly**: when `history`/`prompt` hits an unattached session the impl auto-resumes, deduplicating concurrent triggers with an in-flight table; attachment status is not exposed to clients (`running` already covers it).
- **Cold session handling follows ownership**: `session.history` and the source read for `session.fork` inspect persistence without an Agent, while Agent-bound ordinary-session methods such as `prompt` resume through a deduplicated in-flight table. Session-backed subagents reject that generic resume path, and attachment status is not exposed to clients (`running` already covers it).
- **Approvals/questions**: the requested frame mints a stable rpcId on acceptance; first answer wins, and the host's in-memory pending table (keyed by rpcId) is the only referee; after a mux reopen, still-pending requested frames replay after the subscribed frame (rpcId reused verbatim — refresh recovery). The audit events `approval/asked`/`decided` continue through the durable log — frames = the live control plane, events = the durable audit. **Status**: the contract and frame types are shipped; the host-side pending table/wire answerer is unimplemented (`respond` in `api-proxy.ts` is a stub, always `not-pending`); PendingCard v1 is display-only.
- **No protocol version**: client and host release bound together; `host.describe` has no protocolVersion field; introduce one when an independently released client appears.
- **Reserved-seam discipline**: the map holds only implemented methods; an unknown method fails loud at envelope parse (`bad-request`) — no not-implemented fallback code. The reservation list (implementing = copy the signature into the domain interface + add the map row + add the schema pair): `session.fork`, `prompt.mode` gaining `'inject'`, `task.list`, `host.listModels`, describe gaining `hostInstanceId`. (`session.rename` graduated from this list: it appends a user-source `session/title` event.)

@@ -44,13 +44,13 @@ Implementation homes: registry core and the props-share types in `packages/clien
A service is a plugin's only API surface toward other plugins (UI components and injection faces are not APIs; a plugin nobody calls mounts no service — ui-trajectory is the minimal-plugin exemplar: no ctx service, only view-slot registrations). The roster: `ctx.connection` (api client + stream handles), `ctx.slots` (registry wrapper emitting `slots/changed`, render entry, renderer install seam), `ctx.sessions` (list store, current-session state, scope tree), `ctx.loader`, `ctx.theme`, `ctx.i18n`, `ctx.layout` (cross-plugin view navigation), `ctx.conversation` (send/cancel/startSession). Viewing state that used to live in service stores (panel widths, selection, drafts) now lives in entry-declared stores per the [slot system standard](2026-07-22-slot-type-chain-implementation.md).
There is no registration model besides slots — the former view and tool rings both dissolved into it. Conversation views are entries of the `'conversation.view'` list slot ui-conversation declares, tab metadata rides the registration options (`id`/`order`/`label`), and per-view chrome lives inside the view components themselves. A tool row is a keyed child slot each view declares for itself — today `'conversation.chat.toolview'` (keyed/session), declared by the chat entry's `children` table; the key space is runtime-open (SlotMap declares slots, never keys), which is what the tool ring's open tool-name set required. The render site dispatches per row via `entryKey: toolName` with `GenericToolCard` as the call-site `fallback`; the owner payload is the uniform `ToolRowOwnerProps` (`callId`/`toolName`/`block`/`openDetails`), and `ToolRowProps` composes it with the session standard kit for registrant components. Registrants are plain plugins with zero dedicated machinery: `ctx.slots.register({ name: 'conversation.chat.toolview', key: '<tool>', inject? }, Row)`, with `inject: ['slots', 'conversation']` as the load-order seam (the conversation service being present guarantees the slot is declared). Session-dimension differentiation happens inside the component — `useSessions` reading `parentId` — not in registry predicates; interaction drafts and other row state ride the ordinary store seat. Trajectory/waterfall get same-shaped slots (names fixed by the slot-naming discipline `<domain>.<entry>.<hole>`, one shared owner type) that land with their own row render sites — RendersCheck rejects a declaration nobody renders, so the two slots cannot be declared early.

**Scope addressing** mirrors the host's agent-scope idiom: services are root singletons whose methods take no sessionId — they read the caller's scope mark (`scopeOf(ctx)`). Inside a session scope, `ctx.conversation.send('hi', 'queue')` targets that session; cross-session calls re-target by switching ctx (`ctx.sessions.scope(id)!.conversation.send(...)`); calling a scoped method from root ctx throws. Client session scopes are minted like host agent scopes (a no-op plugin fiber + a scope-key extend), built lazily on first viewing and torn down only when the session is removed and unwatched — host-session death alone does not tear a scope (it freezes into a read-only viewport).

Operations: `prompt`/`cancel` (RPC passthrough; failures land in the snapshot's `promptError`), `open` (pull the tail history page, idempotent), `loadOlder` (upward paging, reentry-guarded), `resync` (reconnect = clear the window and rerun open).

- **ConversationSnapshot** (conversation.ts): the immutable snapshot contract — `nodes` (folded, surface-ordered), `partial`, `runningCalls`, `pending`, `running`, `removed`, `openState`, `hasMore`, `promptError` and kin. **Reference discipline** (the premise of memo and uSES): the top-level object is fresh on every change; the nodes array is rebuilt but element references come from the cache; unchanged substructures reuse the previous snapshot's references.

- **SessionManager** (manager.ts): instance cluster + frame entry + the session list. sessionId-bearing frames go only to existing instances (a mux broadcast must not instantiate every session); approval/question `requested` frames are the exception — they never land in history, so they buffer in `pendingBuffers` and replay on instantiation.
- **Notifier** (notifier.ts): two channels chosen by change source. `markDirty()` (default; frame-driven changes always) batches per microtask — N changes, one notification, one re-render; the flush rebuilds the snapshot cache before notifying. `notifyNow()` (only direct echoes of user gestures) rebuilds and notifies in the same tick — controlled inputs roll the DOM back and jump the caret if their echo defers to a microtask. Frame-driven code using notifyNow collapses batching back to per-frame renders; banned.
- **FoldAdapter / PartialAccumulator**: the fold reuses the core SurfaceManager (`@deepseek-ai/dsh-session/surface`), padding sentinel events so a paged window starting at seq > 0 satisfies the core's `seq === index` assertion; a cross-window replace degrades to a tolerant linear scan and sets `foldDegraded`. Chunks stay out of the fold entirely (O(1) skip): the accumulator folds StreamChunks into `AssistantBlock[]`, a delta swapping only that block's reference, and the finalizing message discards the accumulator in the same batch (no flicker on promotion). Cost model: one chunk = one string concatenation + a dirty mark; an unsubscribed Session under a frame storm costs only the mark.
- **TranscriptAdapter / PartialAccumulator**: the transcript is the append-origin surface projected in log order (`isAppendSurfaceEvent` from `@deepseek-ai/dsh-session/surface`) plus one marker per landed compaction checkpoint — never the model surface, which shadows replaced ranges and would erase conversation the reader already saw. Node order is seq-monotonic by construction, so there is no core `seq === index` assertion to satisfy and no degradation branch. Chunks contribute no node (O(1) skip): the accumulator folds StreamChunks into `AssistantBlock[]`, a delta swapping only that block's reference, and the finalizing message discards the accumulator in the same batch (no flicker on promotion). Cost model: one chunk = one string concatenation + a dirty mark; an unsubscribed Session under a frame storm costs only the mark.
- **ConnectionController** (in `packages/client/connection`): opens the mux/host streams, pumps with for-await, reconnects with exponential backoff (500ms doubling to 10s, jitter, unlimited) behind a generation fence; sinks are injected one-way (the Controller does not know Session). Reconnect = rebuild: `onConnected` → list refresh + per-open-session resync. The object layer faces only `IApiClient`; the Web carriage (HTTP POST for the two client→server quadrants, SSE for the two server→client) and the client class family are the layering RFC's territory.

@@ -14,13 +14,13 @@ After the view ring dissolved into the slot system, the client kept exactly one
The tool ring is gone as independent infrastructure: a tool row is a **keyed child slot each view declares for itself**, and the client has exactly one registration model. The justification above was hollow — a keyed slot's *key space* is already runtime-open (SlotMap declares slots, never keys; the ask-user composer's `key: 'question'` was the precedent), so the open tool-name set fits `entryKey` dispatch natively.
Shipped shape (current-state narrative also in the [architecture note](2026-07-19-gui-web-client-architecture.md)): the chat entry's `children` table declares `'conversation.chat.toolview'` (keyed/session); the render site dispatches per row via `entryKey: toolName` with `GenericToolCard` as the call-site `fallback` (the default card is domain property; the fallback option is ordinary renderSlot grammar). The owner payload is the uniform `ToolRowOwnerProps` (`callId`/`toolName`/`block`/`openDetails` — details being a session-level facility, not chat-private), and `ToolRowProps` pre-composes it with the session standard kit for registrant components. A registrant is a plain plugin: `ctx.slots.register({ name: 'conversation.chat.toolview', key: '<tool>', inject? }, Row)` with `inject: ['slots', 'conversation']` as the load-order seam — apply mounts `ConversationService` *after* the chat registration, so the service being present guarantees the slot is declared, by construction. Session-dimension differentiation happens inside the component (`useSessions` reading `parentId` — the decision sits where all the information already is); the bash sample is the third-party-posture exemplar and paints the same ToolRow chrome as Think (`Bash · {description}`, with a scoped badge only in child sessions). Trajectory/waterfall toolview slots share this exact shape (names fixed by the slot-naming discipline `<domain>.<entry>.<hole>`, one shared owner type) and land with their own row render sites — RendersCheck rejects a declaration nobody renders, so the type system, not convention, blocks early empty declarations.
Shipped shape (current-state narrative also in the [architecture note](2026-07-19-gui-web-client-architecture.md)): the chat entry's `children` table declares `'conversation.chat.toolview'` (keyed/session); the render site dispatches per row via `entryKey: toolName` with `GenericToolCard` as the call-site `fallback` (the default card is domain property; the fallback option is ordinary renderSlot grammar). The owner payload is the uniform `ToolRowOwnerProps` (`callId`/`toolName`/`block`/`openDetails` — details being a session-level facility, not chat-private), and `ToolRowProps` pre-composes it with the session standard kit for registrant components. A registrant is a plain plugin: `ctx.slots.register({ name: 'conversation.chat.toolview', key: '<tool>', inject? }, Row)` with `inject: ['slots', 'conversation']` as the load-order seam — apply mounts `ConversationService` *after* the chat registration, so the service being present guarantees the slot is declared, by construction. The bash sample is the third-party-posture exemplar and paints the same ToolRow chrome as Think (`Bash · {description}`). Trajectory/waterfall toolview slots share this exact shape (names fixed by the slot-naming discipline `<domain>.<entry>.<hole>`, one shared owner type) and land with their own row render sites — RendersCheck rejects a declaration nobody renders, so the type system, not convention, blocks early empty declarations.
Registry-era responsibilities all have successor homes: inject caching and row error isolation ride the framework renderer (entry×scope cache, per-entry `SlotErrorBoundary`); subscribe/getVersion ride the slot core's per-key version machinery; the future "store seat" is the ordinary store seat keyed slots already have (interaction-draft durability is its first named consumer); miss fallback is the call-site `fallback` option.
## Accepted semantic changes
Four behavioral deltas were accepted deliberately, not overlooked. Cross-view appearance is per-view registration — a row must adapt to each view's layout anyway, so one registration per view is the correct coupling, and reuse is the same component in two register calls. Same-key double registration is a loud throw where the registry let later-wins silently override — a discipline correction, not a loss. Session-dimension dispatch moved from registry predicates into the component. Registry-level shape override by third parties (a scoped registration shadowing a global one) has no equivalent; a real future need routes through key-naming conventions or a small in-component resolver, never a revived parallel registry.

- Each materialized Session has exactly one `SessionInputShell` (the facade), created and torn down with the session scope; with no session, no input machine is built. `ConversationRoot` is itself the `session-maybe` resident shell, holding HeroShell, the Workspace picker, the composer stack, and the chain-fallback frame.
- The composer bar is one `session-maybe` slot entry rendered unconditionally: with no session the same InputBar renders inert (machine faces absent, `disabled` owner prop), and once `connectWorkspace` returns a blank session the same instance goes live — the textarea DOM survives the no-session → blank transition and every later phase flip; `ConversationRoot`, the Hero, and the layout skeleton hold throughout.
- ConversationRoot's Hero criterion is `sessionId === undefined || (composerPhase === 'blank' && (openState === 'open' || openState === 'loading'))`. The first submit enters engaging synchronously, and a failure keeps the composer and the error context rather than falling back to the blank Hero; the sidebar's blank bit flips false only after a prompt is successfully accepted.
- Sending unifies in the hub defaultSink: after an optimistic draft clear it goes only through `session.prompt {mode:'queue'|'steer'}`; backfill happens only when it fails and the live draft is still empty — a user who has kept typing is never overwritten. No Draft materialize or attach transaction exists.
- Sending unifies in the hub defaultSink: after an optimistic draft clear it goes only through `session.prompt` with `mode:'queue'` (the Web UI has no steer entry; host-wire `mode:'steer'` remains outside this machine); backfill happens only when it fails and the live draft is still empty — a user who has kept typing is never overwritten. No Draft materialize or attach transaction exists.
- When the blank Hero re-picks the Workspace, the shell calls `connectWorkspace`; if the target session differs, the non-empty draft moves from the current shell to the target shell before the new id is opened, and the old blank session survives but is no longer current.
- The Notifier's two-bit contract: `dirty` (snapshot freshness, clearable by an `ensureFresh` pull) and `notifyPending` (notification debt, cleared only by a flush) are mutually independent — a pull must not swallow a push, and object-layer push subscribers (watchTransaction) depend on this guarantee.

A three-package capability seam in `packages/host/` — `directory-picker` (interface), `directory-picker-native`, `directory-picker-browse` (backends) — with one contract method: `capability()` returns a **discriminated union**, `{ kind: 'native', pick(signal) }` or `{ kind: 'browse', list(path?), createDirectory(path, name) }`. The gateway (`dsh-host-apiproxy`) injects `directoryPicker`, serves the matching RPCs, and answers `directory-picker-unavailable` for the other kind. The union is discriminated because the backends differ in *interaction shape* — flattening them into one method set would force every backend to fake the other's shape.
**The client side is slot-composed, not advertisement-branched.** ui-workspace's two trigger surfaces each declare a `single` directory-flow hole (`conversation.hero.workspace.directoryFlow` / `sidebar.workspaces.directoryFlow`; two keys because a hole has exactly one declaring slot entry — same owner contract, same occupant). Backend packages are **dual-face**: the browser half registers the matching interaction into both holes — `-native` a renderless occupant driving `host.pickDirectory`, `-browse` the in-app Select Workspace Directory dialog. The hole's owner conversation (`open`/`busy`/`onPicked`/`onCancel`/`onError`) carries the whole exchange: ui-workspace keeps the trigger (menu entry rendered only while the hole is occupied) and the adoption (`createWorkspace({path})`, conflict/error dialog, Choose again), the occupant owns everything between `open` and the picked path.

Placement and policy rulings folded into this decision:
@@ -20,7 +20,8 @@ Placement and policy rulings folded into this decision:
- **Dependency survey (hand-roll vs adopt).** Node's stdlib *is* the maintained cross-platform OS layer (`readdir(withFileTypes)`, `homedir`, path semantics); surveyed alternatives fail the dependency bar — file-manager packages (`node-file-manager`, `files-and-folders`, Syncfusion's provider) are whole HTTP apps (fit), drive-letter helpers (`drivelist` native addon, `windows-drive-letters` ~7y stale) fail health/proportionality. The browse backend is a thin adapter over stdlib.
- **Hidden entries: return-and-flag.** The host stamps `hidden` (POSIX dot convention) and returns everything; the client filters. Display policy stays client-side, and the show-hidden toggle shipped as exactly that client-only change: a fixed-label footer toggle whose state lives in the pressed presentation (`aria-pressed` + check glyph), a dot-led path-draft prefix reveals the hidden entries it names, and the current selection is exempt from both the hidden and the prefix filter (it anchors the two-pane view). Windows' `FILE_ATTRIBUTE_HIDDEN` is not exposed by dirents — documented limitation until a native probe pays for itself.
- **Path-editor cancel scope: the dialog card.** The browse client's path editor cancels on Escape and on focus leaving the card, both observed at a card-scope wrapper rather than the input — after Tab parks focus on a filtered row the input is off the event path, yet Escape must collapse the editor (not the dialog) and a later focus departure must still cancel. Non-cancel exemptions: window/tab focus loss, in-card focus moves, and pointer paths (rows and the toggle suppress focus steal on mousedown while editing). Separators for seeding and draft-tail filtering are inferred from `listing.home`; the wire-field alternative below records the deferred authoritative form. Combobox semantics between the editor and the list it filters (`aria-expanded`/`aria-controls`/active-descendant, result announcements) are likewise deferred — today they read to assistive tech as separate widgets.
- **Navigation lands selection-anchored, quiet, and bounded.** Away from the display root (the same collapse the crumb header renders, so crumbs and pane shape never disagree), the landing is two-pane: the target's actual parent-level entry re-selected (platform case folding on Windows), its children on the right, so a crumb jump reads as stepping back one pane rather than collapsing to a single column. Target and parent legs land as **one frame** when the parent leg settles within the 200ms wait bound — the stale view keeps rendering until then, so navigation swaps the panes without an intermediate single-pane flash — and past the bound the target commits alone at once (an Enter-submitted navigation is never held hostage by a stalled parent) with the late parent leg upgrading the landing in place. The parent leg runs under the landing's supersession scope and is aborted on the wire by any newer intent (Escape inside the landing window therefore withdraws the whole navigation); a failed parent leg, or a truncated parent window lacking the target, leaves the single-pane landing — the upgrade must never orphan the selection it exists to anchor. The loading indicator follows the same quiet rule: it floats over the content's bottom-right corner (never a layout-shifting row; the truncated/error rows own the bottom left and keep rendering through a scan) and only once a scan outlives a 300ms silence window, so a local listing swaps with nothing shown at all. Row picks are deliberately exempt from the one-frame rule: a pick's immediate pane split is its selected-state feedback (aria-current, crumbs following), while a navigation has nothing to acknowledge the click but the swap itself. Both timing constants are calibrated for local enumeration; a remote deployment (one RPC per level, commonly 100–400ms) would sit inside the silence window with no pressed state on the crumbs — revisit the window or add pressed feedback when a remote consumer lands.
- **The path editor advertises itself, and the panes follow the draft.** The click-to-edit zone is not invisible: a pencil glyph sits at the bar's right edge and hover/focus lights the WHOLE bar in the editor's own box — the bar carries the outline and padding in both modes, so the hover previews exactly the field the click produces and nothing resizes when zone and input swap. While the editor is open the panes track the draft instead of whatever level happened to be listed when it opened — the final segment prefix-filters the level its directory part names, a tail nobody matches releases the filter (a name still being spelled must not empty the pane it is being spelled into), and any other directory part is scanned after a 250ms rest and lands through the same selection-anchored, two-pane landing every navigation uses, so typing a path moves the Miller view exactly as a crumb jump does — typing deeper descends, erasing segments walks back up — without leaving the editor. **The pane arity is the invariant**: the last pane always lists the level the path names, with its parent beside it and nothing but a display root listing alone. Skipping the scan whenever *any* pane happened to list the directory was the cheaper rule and the wrong one — erasing a segment then left the level being typed on the left with its own child pane still standing to its right, so the panes stopped reading as "where I am, and where I came from". Only the last pane's own tail costs no scan. One landing shape, two callers: a submitted path closes the editor and announces failures, the draft-following scan keeps both to itself. That scan is speculative — half-typed directories are unreadable most of the time — so a failure keeps the last readable panes and stays silent. Enter remains the authoritative commit: it owns the view from submission until landing (a debounce timer armed by the same keystrokes is held back rather than superseding the navigation, and a rejected submission stays held until the next edit) and it alone surfaces the failure. Two consequences are deliberate. The wait is keyed on the draft, not on the directory part it names, so a keystroke that superseded an in-flight scan re-arms one and an edit after a rejected submission releases the hold; the panes it reads are a ref rather than a dependency, or the landing would re-arm the wait and a host answering with a differently spelled path would scan forever. And a walk is not rewound: closing the editor — cancellation included — leaves the panes where the draft took them, named by the crumbs and followed by Open's fallback target, because the operator watched them move. A landing that unmounts the row a keyboard operator Tabbed onto re-parks focus on the editor, since the Modal has no focus trap. Two further rules keep one keystroke to one movement: the walk waits BOTH legs out rather than taking the submitted-navigation wait bound (nothing waits on a speculative scan, so landing single-pane and upgrading would be the very flash this exists to avoid, and it would strand the two-pane view whenever a tail keystroke aborted a slow parent leg), and the tail filters only the LAST pane — narrowing a pane the draft has walked away from would move the view once as it narrows and again as its landing replaces it. A level also keeps answering the directory text that produced it (`scanned`), because the Host resolves what it is given: `..` segments and, on Windows, forward slashes reach a level whose own path spells the request differently, and without the memo those drafts would rescan on every keystroke and never filter.

The loading indicator follows the same quiet rule: it floats over the content's bottom-right corner (never a layout-shifting row; the truncated/error rows own the bottom left and keep rendering through a scan) and only once a scan outlives a 300ms silence window, so a local listing swaps with nothing shown at all. Row picks are deliberately exempt from the one-frame rule: a pick's immediate pane split is its selected-state feedback (aria-current, crumbs following), while a navigation has nothing to acknowledge the click but the swap itself. All three timing constants — the 200ms parent-leg bound, the 300ms silence window, and the editor's 250ms draft rest — are calibrated for local enumeration; a remote deployment (one RPC per level, commonly 100–400ms) would sit inside the silence window with no pressed state on the crumbs, and would pay rest plus RPC before the panes follow a typed path — revisit all three together when a remote consumer lands.
- **Symlinks: follow for enterability.** `stat` probes symlinks (broken/cyclic → skipped); crumbs keep the logical path the operator navigated, and `workspace.create` already canonicalizes via realpath at adoption.
- **Listing levels are bounded, and streamed.** One `list` call returns at most `maxEntries` rows (config, default 1000 — GitHub's web-UI directory-listing bound). The level streams via `opendir` into a name-sorted window of `maxEntries + 1` candidates, so memory stays O(maxEntries) and enterability probing touches only windowed candidates; the wire `DirectoryListing` carries a required `truncated` flag so the client states incompleteness instead of silently missing tail entries. A windowed broken symlink is not backfilled from beyond the window — the eviction already marks the level truncated. Window insertion is binary with an O(1) full-window tail rejection (an oversized level must not pay a window scan per dirent), and `list(path, signal)` threads the carrier's request signal so a scan of a stalled network directory cannot outlive a disconnected caller — every await in the scan (open, each read, each symlink probe) races the signal, an aborted exit abandons rather than awaits the close (Node queues close behind in-flight reads), and abandoned settlements are swallowed so cleanup can never surface as an unhandled rejection. An unbounded level is a memory/responsiveness hole for large or adversarial directories.
- **Whole-filesystem scope, no roots config.** `workspace.create` accepts arbitrary paths and the API serves bash-driving methods, so a browse root would be UX scoping, not a boundary; configurability without a consumer fails the evidence bar. Deferred until a deployment needs it.
@@ -34,6 +35,9 @@ Placement and policy rulings folded into this decision:
- **Adopting a file-manager/drive-enumeration dependency.** Rejected per the survey above; recorded here as the dependency policy requires.
- **A flip-label show-hidden toggle ("Hide hidden files").** Rejected: a flipping action label is ambiguous between state and action and doubles the negative; the fixed label with a pressed presentation states both at once.
- **Pure relatedTarget blur cancellation (no mousedown suppression).** Rejected: Safari does not focus buttons on pointer down, so a click's focusout carries a null `relatedTarget` and would cancel the editor before the click lands; editing-scoped mousedown suppression plus the card-anchored relatedTarget guard covers pointer and keyboard paths together.
- **A permanently visible path input above the Miller view.** Rejected: the breadcrumb is already the "where am I" reading, and a second always-present field duplicates it while costing a row of a 500px card that the columns need. The glyph plus the hover-lit zone puts the affordance on the bar that already answers the question.
- **Scanning the draft on every keystroke, or only on Enter.** Per keystroke: walking one path segment issues a listing per character, most of them for directories the operator is typing through, not at. Only on Enter (what shipped first): the panes and the typed text disagreed for the whole edit — the complaint this bullet answers. The 250ms rest keeps one scan per directory the typing actually settles on.
- **Emptying a pane on a prefix miss (what shipped first).** Rejected: mid-name the miss is the normal state, so the pane blanked exactly while the operator needed it to confirm the name; releasing the filter keeps the level readable and costs only the transient wideness.
- **A wire `separator` field on `DirectoryListing` (host stamps `path.sep`).** Deferred, not rejected: it is the authoritative form — a POSIX home directory containing a backslash defeats the `listing.home` heuristic — but it touches the seam type and every backend; the browse client's `separatorOf` carries a TODO pointing at this alternative until a wire change is next scheduled.

# Agent Note: Projected token usage and context occupancy
Status: implemented
English | [中文](2026-07-29-projected-token-usage-and-request-context.zh.md)
## Problem
The Web stats line derived token totals from the currently loaded conversation nodes. That window is paged, so scrolling changed the totals, and compaction replaces visible content without preserving the billing behind it. Durable provider billing needs a source that survives both.
Context occupancy needs a numerator and a denominator that no existing surface carried to the browser: the prompt size of the latest request, and the capacity of the route it used.
## Decision
Both values are ordinary durable session-projection state. `@deepseek-ai/dsh-token-meter` registers two units when `ctx.sessionProjections` is present.
`tokenUsage` folds the complete durable log into uncached input, output, cache-read, and cache-write buckets. An `assistant/chunk` usage sample survives a later failed request; an `assistant/message` usage value for the same `(turn, step)` replaces the earlier sample instead of double-counting it. Reasoning stays an output subdivision. Compaction and surface replacement do not erase earlier billing.
`contextPressure` carries optional `pressureTokens` — the newest provider-reported prompt size, summing uncached input plus cache reads and writes, excluding output — and optional `contextWindow` from the newest `request/context` record. Neither field is synthesized before its source exists.
`request/context` is a new log-only session event recording registration-bound metadata for the route a request resolved to. AgentLoop appends it inside the step beside `request/header`, from the context metadata `prepareCall()` now returns alongside the resolved config — the same registration-bound lookup that already validated reasoning, so no second resolve happens. It is skipped when provider, model, and capacity all match the previous record. A route whose adapter advertises no capacity is recorded with `contextWindow` absent, clearing an older route's denominator.
Capacity deliberately stays out of `EpochHeader`. That type is the reconstruction contract — what a request was built from — and `headerEquals` compares it field-wise to decide whether a snapshot is a real `change`. Capacity is adapter metadata describing a route, so placing it there would let a capacity change masquerade as a request-envelope change and would drag it into the loop's reconstruction invariant.
Both units ride the standard projection lifecycle: history tail baselines, `session/projection` live frames, higher-seq-wins client storage, JSON checkpoints, cache recovery, and unit unload. There is no token-specific history field, mux frame, projector, revision counter, or client fence.
The Web `StatsLine` reads both through the standard `useProjection` seat. Window nodes still supply turn and step counts plus LLM and tool wall times — those answer "what is on screen" and are correctly window-scoped. Durable token and context groups remain when compaction leaves no visible assistant step. Cache writes count in billed input and in the cache-hit denominator. A deployment without token-meter drops the token groups; occupancy stays hidden until both pressure and capacity are known.
## Context occupancy is approximate, and that is the decision
`pressureTokens` and `contextWindow` are independent last-wins fields, not one atomic observation. Switching models pairs a fresh capacity with the previous route's pressure until the next request reports usage, and the numerator describes the last request rather than the surface as it currently stands.
This was accepted deliberately. An occupancy percentage is a user-facing reference figure: nothing in the harness makes decisions from it, and compaction reads `measure()` directly instead. The TUI status line has always computed occupancy this way, dividing a `measure()` total by a capacity resolved separately for the selected model — so an atomic variant here would have been the outlier, not the norm.
Reviewers should not treat the non-atomicity as a defect awaiting a fix. A consumer that genuinely needs an exact same-boundary figure should call `ctx.tokenMeter.measure()` at its own request boundary, where both values are available together, rather than read this projection.
## Alternatives considered
**An atomic request-boundary snapshot delivered as a transient mux frame (implemented, then rejected).** An earlier revision of this branch emitted `session/model-request`: one non-replayable frame carrying `contextTokens` and `contextWindow` measured at the same `agent/model-request` boundary. Being the only non-replayable class on the mux stream is what broke it. Host and mux are independent SSE streams with no cross-stream ordering, so a request emitted before a removal could arrive after `host/session-removed` and revive a dead session's telemetry, while a legitimate request for a new lifecycle reusing the same id could be fenced by a late removal. `session/subscribed` is not lifecycle proof — it says a queue began subscribing to an id, not that a new in-memory session replaced an older one — and `lastSeq` is a durable watermark two lifecycles can share. A correct fix required a monotonic lifecycle generation on the frame, on subscription, and on removal, plus a client watermark comparison.
That cost bought a worse display: occupancy went blank after every reconnect and never moved while a conversation grew. It also made ApiProxy a measurement site calling the O(surface) `measure()` on every request, and expressed reconnect state through a synthetic `cancelled` open error the UI had to special-case.
**Fold the loaded node window in React.** Cannot survive pagination or compaction, and makes a presentation package reconstruct log semantics.
**Publish usage only with final assistant messages.** A request that reports a usage chunk and then fails would lose its billing.
**Resolve capacity inside token-meter.** The package documents itself as independent of model routing and is otherwise a pure reader that never appends to the log. AgentLoop already holds the resolved metadata where the header is written.
**Extend the `session.models` RPC with capacity.** The handler already resolves and discards it, so the field is nearly free — but `StatsLine` lives in `ui-conversation` while the model directory lives in `ui-model`, and `ui-conversation` cannot depend on `ui-model`. Delivering it would have required either a second dock entry splitting one text row across two plugins, or a cross-plugin store write.
**Add a context circle beside the model selector.** That placement suggests selected-model state. The stats line carries the figure without a duplicate UI or data path.
## Consequences
Token totals stay stable across pagination, compaction, replay, restart, and reconnect, because they are ordinary durable projection state recovered through the generic paths. The cross-stream reordering race is gone by construction rather than fenced.
Occupancy is approximate in the ways documented above. It is available immediately after restore or reconnect, since both fields are durable, at the cost of describing the last recorded request rather than an exact current boundary.
Each session log gains one small `request/context` record per route or advertised-capacity change. The token-meter projection is the canonical owner of durable session-projection usage semantics; the TUI retains its live per-step map because it does not mount the generic projection seam, and the standalone browser fixture mirrors the unit. ApiProxy carries no token-specific code, owns no per-session metrics cache, and performs no measurement. The browser keeps two generic projection values and no connection-local telemetry, and streaming text deltas still do not force the stats line to recompute.

# Agent Note: token 用量投影与上下文占用率
Status: implemented
[English](2026-07-29-projected-token-usage-and-request-context.md) | 中文
## 问题
Web 统计行原先从当前已加载的会话节点推导 token 总量。该窗口是分页的,因此滚动会改变总量;压缩(compaction)又会替换可见内容,而不保留其背后的计费用量。持久的提供方计费用量需要一个能同时经受这两者的数据源。
上下文占用率需要一个分子和一个分母,而这两者都不曾由任何既有接口送达浏览器:最新一个请求的提示词规模,以及该请求所用路由的容量。
## 决策
这两个值都是普通的持久会话投影状态。当 `ctx.sessionProjections` 存在时,`@deepseek-ai/dsh-token-meter` 会注册两个单元。
`tokenUsage` 将完整持久日志归并为未缓存输入、输出、缓存读取和缓存写入四类计数项。即使后续请求失败,`assistant/chunk` 用量样本仍会保留;同一 `(turn, step)` 的 `assistant/message` 用量值会替换先前样本,不会重复计数。推理(reasoning)仍是输出的细分项。压缩和表层替换不会抹除先前的计费用量。
`contextPressure` 携带可选的 `pressureTokens`(提供方报告的最新提示词规模,为未缓存输入加缓存读取与写入之和,不含输出),以及来自最新一条 `request/context` 记录的可选 `contextWindow`。在各自来源出现前,两个字段都不会被合成。
`request/context` 是新增的仅入日志会话事件,记录请求所解析到的路由的、绑定注册项的元数据。AgentLoop 在步骤内紧随 `request/header` 追加它,数据取自 `prepareCall()` 现在与已解析配置一并返回的上下文元数据:正是那次已经校验过推理的、绑定注册项的查询,因此不会发生第二次解析。当提供方、模型和容量都与上一条记录相同时会跳过。适配器不公布容量的路由会以缺失 `contextWindow` 的形式记录,从而清除较早路由的分母。
容量刻意不进入 `EpochHeader`。该类型是重建契约,即请求由什么构建而成,而 `headerEquals` 会逐字段比较它,以判定某个快照是否真的是一次 `change`。容量是描述路由的适配器元数据,把它放进去会让容量变化伪装成请求封装的变化,还会把它拖进 AgentLoop 的重建不变式。
两个单元都沿用标准投影生命周期:历史尾页基线、`session/projection` 实时帧、seq 高者胜的客户端存储、JSON 检查点、缓存恢复和单元卸载。系统没有任何 token 专用的历史字段、mux 帧、投影器、修订计数器或客户端栅栏。
Web `StatsLine` 通过标准 `useProjection` 席位读取两者。窗口内节点仍提供轮次和步骤计数,以及 LLM(大语言模型)与工具的墙钟时间:它们回答的是「屏幕上有什么」,按窗口作用域正是正确的。压缩使可见 assistant 步骤归零后,持久 token 与上下文分组仍会保留。缓存写入会计入计费输入和缓存命中率分母。未部署 token-meter 时会去掉 token 分组;只有压力与容量都已知时才显示占用率。
## 上下文占用率是近似值,而这正是决策本身
`pressureTokens` 与 `contextWindow` 是两个各自后者胜的独立字段,不是一次原子观测。切换模型时,新容量会与上一路由的压力配对,直到下一个请求报告用量为止;分子描述的是最后一个请求,而不是此刻的表层。
这是刻意接受的结果。占用率百分比是面向用户的参考数字:harness 中没有任何环节依据它做决策,压缩改为直接读取 `measure()`。TUI 状态行一直以这种方式计算占用率,即用 `measure()` 总量除以为所选模型单独解析出的容量;因此在这里做成原子版本才是异类,而不是常态。
评审人不应把这种非原子性当作待修的缺陷。确实需要同一边界精确数字的消费方,应在自己的请求边界调用 `ctx.tokenMeter.measure()`,那里两个值同时可得,而不是读取该投影。
## 备选方案
**以临时 mux 帧交付请求边界上的原子快照(已实现,随后否决)。** 本分支较早的一个修订版会发出 `session/model-request`:一个不可回放的帧,携带在同一个 `agent/model-request` 边界测得的 `contextTokens` 与 `contextWindow`。真正让它失效的,是它成了 mux 流上唯一的不可回放类别。Host 流与 mux 流是两条独立的 SSE(Server-Sent Events)流,彼此之间没有顺序保证:在移除之前发出的请求可能在 `host/session-removed` 之后才到达,让一个已死会话的遥测数据复活;而复用同一 id 的新生命周期的合法请求,又可能被一条迟到的移除拦下。`session/subscribed` 不能证明生命周期:它只说明某个队列开始订阅某个 id,而不说明新的内存会话替换了较早的会话;`lastSeq` 则是两个生命周期可以共用的持久水位线。正确的修法需要在帧上、订阅上和移除上都带一个单调递增的生命周期代次,再加上一次客户端水位线比较。
这份代价换来的是更差的显示:占用率在每次重连后变为空白,而且会话增长期间从不移动。它还把 ApiProxy 变成一个测量点,每个请求都要调用 O(surface) 的 `measure()`,并通过一个 UI 必须特殊处理的、连接打开时的合成 `cancelled` 错误来表达重连状态。
**在 React 中归并已加载的节点窗口。** 无法跨分页或压缩保留数据,还会迫使展示包(package)重建日志语义。
**仅随最终 assistant 消息发布用量。** 如果请求报告一个用量分片后失败,就会丢失自己的计费用量。
**在 token-meter 内部解析容量。** 该包自述与模型路由无关,且在其他方面是一个从不向日志追加内容的纯读取方。AgentLoop 在写入请求头的位置已经持有已解析的元数据。
**为 `session.models` RPC 增加容量字段。** 其处理器已经解析出容量又将其丢弃,因此这个字段几乎是免费的;但 `StatsLine` 位于 `ui-conversation`,模型目录位于 `ui-model`,而 `ui-conversation` 不能依赖 `ui-model`。要送达它,就得增加第二个 dock 条目、把一行文本拆到两个插件里,或者做一次跨插件的 store 写入。
**在模型选择器旁增加上下文圆环。** 该位置会让人以为这是所选模型的状态。统计行可以承载该数字,无需引入重复的 UI 或数据路径。
## 后果
token 总量在分页、压缩、回放、重启和重连期间保持稳定,因为它们是通过通用路径恢复的普通持久投影状态。跨流重排序竞态从构造上就不存在,而不是被栅栏挡住。
占用率在上文记录的意义上是近似值。由于两个字段都是持久的,它在恢复或重连后立即可用;代价是它描述的是最后一条已记录的请求,而不是精确的当前边界。
每个会话日志会为每次路由或已公布容量变化增加一条小型 `request/context` 记录。token-meter 投影是持久会话投影用量语义的正典所有方;TUI 未挂载通用投影 seam,因此保留自己的实时逐步骤 map,而独立浏览器 fixture 会镜像该单元。ApiProxy 不携带任何 token 专用代码,不拥有逐会话指标缓存,也不执行测量。浏览器只保留两个通用投影值,不保留连接本地的遥测数据;流式文本增量仍不会迫使统计行重新计算。

# Agent Note: Package-manager-native repository cache
Status: implemented
English | [中文](2026-07-30-package-manager-native-repository-cache.zh.md)
## Problem
A standalone Harness app cannot rely on a developer-owned SDK project to declare and install repository dependencies. Loading a configured GitHub repository therefore needs a persistent fetch, preparation, and cache boundary, but implementing Git transport, hosted-source syntax, package preparation, and a content store inside DSH would duplicate a package manager. Requiring a separately installed package manager would make a config-only feature depend on host setup.
The cache also needs an update identity. A mutable branch name cannot both remain permanently cached and reflect later commits without an independent refresh protocol.
## Decision
Vendored `@cordisjs/plugin-loader/repository` exports `RepositoryCache`, a generic Node-only package helper with no DSH plugin-format knowledge. Keeping it on a subpath prevents browser consumers of the Loader's main entry from traversing Node filesystem and child-process imports. The caller supplies a package-manager-native source specifier and a cache root. DSH-specific callers own accepted source syntax, path selection, and the cache-root location; the [SDK project dependency workflow](../../proposed/feature/2026-07-17-sdk-follow-up-capabilities.md#external-cordis-plugin-installation) remains a separate path owned by the developer project's selected package manager.
The Loader carries an exact runtime dependency on `pnpm@11.7.0` and invokes that package's JavaScript entry with the current Node executable. It never discovers a global executable or delegates through Corepack. Each cache miss creates an isolated project with one dependency named `repository`; pnpm owns Git/GitHub resolution, fetching, its content-addressed store, dependency installation, and lifecycle scripts in the repository's dependency graph.
The isolated workspace sets `dangerouslyAllowAllBuilds: true`. A configured repository and its dependency graph are trusted executable code: lifecycle scripts may run before DSH reads any declared assets. The child receives ordinary host process state needed by Git and pnpm, but ambient credential-shaped (`KEY`, `PASSWORD`, `SECRET`, `TOKEN`) variables are removed. No OAuth, token forwarding, or private-repository authentication contract is added.
The SHA-256 of the exact specifier names the cache entry. Concurrent same-process requests share one task. Installation occurs in a sibling temporary directory; only a successful install with a package directory and marker is atomically renamed into the final key. Failed staging is removed, and a competing process's already-published valid entry wins. A later process validates the marker and package directory before returning the stable `node_modules/repository` path.
An identical specifier permanently reuses its published entry. The caller changes the ref or another part of the specifier to request a new generation; the cache does not poll remotes, reinterpret mutable refs, expire entries, or garbage-collect old generations.
## Alternatives considered
**Implement GitHub download, archive extraction, preparation, and caching directly.** Rejected under the [dependency policy](../process/2026-07-26-dependencies-over-hand-rolling.md): pnpm already owns hosted Git syntax, Git execution, lifecycle policy, and a shared content store. A second resolver would add more code while still needing package semantics.
**Require `pnpm` on `PATH` or invoke Corepack.** Rejected because changing one app config must be sufficient on every supported installation. Pinning and shipping the CLI also makes the preparation policy reviewable and independent of the host's package-manager version.
**Resolve a branch or tag again on every startup.** Rejected because it turns startup into a network refresh, changes code without a config diff, and makes rollback depend on remote state. Explicit ref changes preserve auditability even when a user deliberately chooses a mutable ref.
**Disable repository lifecycle scripts.** Rejected because common plugin repositories need a declarative `prepare` step to validate and package their plugin subdirectory. The trust boundary is explicit configuration of executable source, not an incomplete illusion that only static files can run.
**Introduce a Cordis repository service.** Rejected because cache lookup has no runtime contribution registry or provider variation. A small helper lets the later host own Cordis lifecycle and HMR without adding a service seam prematurely.
## Consequences
- Standalone apps carry pnpm's approximately 18.6 MB unpacked runtime instead of requiring a global tool or owning a Git/package implementation.
- A repository author may use ordinary package preparation, and a malicious configured repository or dependency can execute code with the scrubbed child environment and the user's filesystem authority.
- Exact specifiers make startup deterministic after the first successful install; changing cached code requires a config/ref change.
- Failed installs leave no published cache entry and may be retried. Published corruption fails loud instead of silently reinstalling under the same identity.
- Cache generations consume disk until a future explicit cache-management policy removes them.
## Testing
`packages/ui/app-boot/tests/repository-cache.spec.ts` covers same-process single-flight, cross-instance cache reuse, exact-specifier separation, failed-stage cleanup and retry, and boundary validation. Its real local-Git case invokes the bundled pnpm, runs the fixture repository's `prepare` script, and reads the prepared file from the installed cache entry without network access.

# Agent Note: 包管理器原生仓库缓存
Status: implemented
[English](2026-07-30-package-manager-native-repository-cache.md) | 中文
## 问题
独立运行的 Harness 应用不能依赖开发者自有的 SDK 工程来声明并安装仓库依赖。因此,加载配置中的 GitHub 仓库需要一道持久的获取、准备与缓存边界;但如果在 DSH 内实现 Git 传输、托管来源语法、包(package)准备流程和内容存储,就会重复实现包管理器。若要求用户另行安装包管理器,则只需修改配置即可使用的功能还会依赖宿主环境的额外配置。
缓存还需要明确更新标识。若没有独立的刷新协议,可变分支名无法既永久缓存,又反映后续 commit。
## 决策
vendor 中的 `@cordisjs/plugin-loader/repository` 导出 `RepositoryCache`:一个不包含 DSH 插件格式知识、仅限 Node 使用的通用包辅助工具。把它保留在子路径上,可以避免 Loader 主入口的浏览器消费方在解析依赖时遍历到 Node 文件系统和子进程 import。调用方提供包管理器原生的来源 specifier 和缓存根目录。DSH 专属调用方负责规定可接受的来源语法、路径选择与缓存根目录位置;[SDK 工程依赖工作流](../../proposed/feature/2026-07-17-sdk-follow-up-capabilities.md#external-cordis-plugin-installation)仍是另一条路径,由开发者工程选定的包管理器负责。
Loader 将 `pnpm@11.7.0` 作为固定版本的运行时依赖,并使用当前 Node 可执行文件调用该包的 JavaScript 入口。它绝不探测全局可执行文件,也不经 Corepack 调用。每次缓存未命中都会创建一个隔离工程,其中只有一个名为 `repository` 的依赖;Git 与 GitHub 来源的解析和获取、pnpm 自身的内容寻址 store、依赖安装,以及仓库依赖图中的生命周期脚本均由 pnpm 负责。
隔离工作区设置 `dangerouslyAllowAllBuilds: true`。用户配置的仓库及其依赖图都属于受信任的可执行代码:DSH 读取任何已声明资产之前,生命周期脚本就可能运行。子进程会收到 Git 与 pnpm 所需的常规宿主进程状态,但会移除环境中名称形似凭据(`KEY`、`PASSWORD`、`SECRET`、`TOKEN`)的变量。该机制不新增 OAuth、token 转发或私有仓库认证契约。
缓存项以精确 specifier 的 SHA-256 命名。同一进程内针对相同 specifier 的并发请求共享一项任务。安装在同级临时目录中进行;只有安装成功且存在包目录和标记时,系统才会把暂存目录原子重命名为最终键对应的目录。失败的暂存目录会被删除;如果另一进程已发布有效项,则以该项为准。后续进程会先校验标记与包目录,再返回稳定的 `node_modules/repository` 路径。
相同的 specifier 会永久复用已发布项。调用方通过修改 ref 或 specifier 的其他部分来请求新的缓存代次;缓存不会轮询远端、重新解释可变 ref、让条目过期,也不会垃圾回收旧代次。
## 曾考虑的替代方案
**直接实现 GitHub 下载、归档解压、准备与缓存。** 根据[依赖政策](../process/2026-07-26-dependencies-over-hand-rolling.md)不予采纳:pnpm 已负责托管 Git 语法、Git 执行、生命周期政策和共享内容存储。第二套解析器会增加更多代码,却仍需实现包语义。
**要求 `pnpm` 位于 `PATH` 上,或调用 Corepack。** 不予采纳:在每种受支持的安装形态中,只修改一份应用配置就必须足以启用该功能。固定并随应用分发 CLI(命令行界面)还能使准备政策可供评审,并与宿主的包管理器版本无关。
**每次启动都重新解析分支或 tag。** 不予采纳:这会把启动变成网络刷新,在配置 diff 未变化时更改代码,并让回滚依赖远端状态。即使用户有意选择可变 ref,显式修改 ref 仍能保持可审计性。
**禁用仓库生命周期脚本。** 不予采纳:常见插件仓库需要声明式 `prepare` 步骤来校验并打包插件子目录。信任边界是显式配置可执行来源,而不是营造一种不完整的假象,仿佛只有静态文件能够运行。
**引入 Cordis 仓库服务。** 不予采纳:缓存查找没有运行时贡献注册表,也不存在提供方变体。小型 helper 让后续宿主负责 Cordis 生命周期与 HMR(热模块替换),无需过早新增服务 seam。
## 后果
- 独立应用随附 pnpm 约 18.6 MB 的解压后运行时,不要求全局工具,也无需自行实现 Git 与包处理。
- 仓库作者可以使用常规包准备流程;恶意的已配置仓库或依赖可以在经过上述清理的子进程环境中,以用户的文件系统权限执行代码。
- 精确 specifier 使首次安装成功后的启动具有确定性;更改缓存代码必须修改配置或 ref。
- 安装失败不会留下已发布缓存项,可以再次重试。已发布缓存损坏时会明确报错,而不会在同一标识下静默重装。
- 缓存代次会持续占用磁盘,直到未来有明确的缓存管理政策将其移除。
## 测试
`packages/ui/app-boot/tests/repository-cache.spec.ts` 覆盖同进程 single-flight、跨实例缓存复用、精确 specifier 隔离、失败暂存清理与重试,以及边界校验。其真实本地 Git 用例会调用随附的 pnpm,运行 fixture(测试前置数据)仓库的 `prepare` 脚本,并在不访问网络的情况下,从已安装缓存项中读取准备后的文件。

A boundary written at persistence load would miss both fork paths — and a forked child inheriting a still-running parent's open `compact/start` is precisely the case that must be classifiable. A boundary written at loop start would miss `fork()` and `adopt()`, and would have to fire on `SessionStartSource: 'startup'`, which is what a fork child publishes, so that field would stop discriminating.

`session/end-seed` joins the on-disk vocabulary. Under the pre-release stance (`SESSION_FORMAT_VERSION` pinned at `0`, no compatibility promise) older logs simply lack it, and a log without a boundary correctly classifies nothing as constructor-seed history.
Not built here: no plugin reads the boundary yet. Wiring the compaction seam's staleness check to it is the follow-up that motivated this boundary; the predicate helper belongs with that seam, where a real consumer decides its shape, rather than shipping into core untested against one.
The [queued manual compaction decision](../feature/2026-07-30-queued-manual-compaction.md) now supplies the first consumer. Its tail scan independently finds the unmatched `compact/start` and newest end-seed, treats only a start after that boundary as live, and clears the invariant trace on the same replay transition. The predicate remains in the compaction package rather than becoming a generic core helper.

# Agent Note: Static repository Plugin format
Status: implemented
English | [中文](2026-07-30-static-repository-plugin-format.zh.md)
## Problem
A repository that already contains reusable skills or an MCP server declaration should be usable by standalone Harness applications without becoming a Harness SDK project or rewriting its existing layout. Popular repositories must be able to add one `.dsh-plugin` directory while keeping their current skills and `.mcp.json` elsewhere in the tree. At the same time, treating an arbitrary repository entry point as a Cordis Plugin would make every repository a new unrestricted runtime extension surface and would bypass the existing skill and MCP lifecycle owners.
The [package-manager-native repository cache](2026-07-30-package-manager-native-repository-cache.md) prepares an exact package source but intentionally knows nothing about DSH formats. This layer therefore needs a package-manager-compatible authoring format, a deterministic prepared artifact, and a Cordis composition that stays transactional under Loader disposal and replacement.
## Decision
`@deepseek-ai/dsh-repository-plugin` owns a restricted `.dsh-plugin` package format with two contribution kinds only: skill roots and one common `.mcp.json`. Its package metadata uses `package.json#dsh.skills` for relative skill-root paths and `package.json#dsh.mcpServers` for the relative MCP document path. At least one is required. Each path may leave `.dsh-plugin` to reuse repository content but must remain beneath the directory containing that `.dsh-plugin`; a nested selectable Plugin therefore owns the adjacent subtree above its package without gaining access to unrelated host paths.
The `.dsh-plugin` package declares `dsh-plugin-prepare` as its ordinary package-manager `prepare` script. The helper validates metadata and source types, strictly parses `.mcp.json`, copies static assets into `dsh-plugin-assets`, and writes `dsh-plugin.mjs`. The `.mjs` extension avoids imposing `type: module` on repository-authored package metadata. The generated module is a fixed import-free template containing only a normalized manifest, an `inject` list derived from it (`loader`, plus `skills` and/or `tools` per the declared capabilities, so the wrapper fiber gates on the services its children need), and delegation to the `dsh-repository-plugin` Loader builtin. Preparation never discovers, transpiles, bundles, or preserves a custom repository entry point.
Loading the DSH package registers that builtin as an effect. A generated wrapper mounts the builtin as its child with `import.meta.url`, so all contributions belong to the wrapper fiber and disappear on Loader removal or rollback. The builtin revalidates the prepared manifest and path containment before reading assets. It composes the existing implementations rather than registering skills or MCP tools itself.
Each prepared skill set mounts `dsh-skill-local` with a unique `repository:<package-name>` provider name, only the copied custom roots, and watching disabled. `dsh-skill-local` therefore gains two general configuration fields: `providerName` and `includeDefaultRoots`. Their defaults preserve its existing single local provider; repository instances set a distinct name and exclude project/user roots so multiple instances neither collide nor duplicate host-local discovery.
Each `.mcp.json` server becomes one existing `dsh-mcp-client` child. The adapter accepts the common root `{ "mcpServers": ... }`; stdio definitions allow only optional `type: "stdio"`, `command`, `args`, and `env`, while HTTP definitions allow only `type: "http"`, `url`, and `headers`. Exact `${NAME}` process-environment references expand at runtime, after cache preparation; missing names fail Plugin load. HTTP maps to the client's Streamable HTTP transport, and stdio uses the prepared package directory as `cwd`. The existing client alone owns connection attempts, failure logging, remote tool synchronization, tool calls, and disconnects. Consequently an MCP connection failure keeps its established successful-plugin/no-tools behavior and is not reclassified as a repository preparation or Loader failure.
Unknown MCP fields reject. This intentionally excludes OAuth, `auth` objects, `CLAUDE_PLUGIN_ROOT`, and a broader Claude compatibility contract. Hooks, commands, agents, apps, arbitrary Cordis code, marketplaces, and discovery are also unsupported. Repository subdirectory selection and GitHub source configuration belong to the [standalone app integration](../feature/2026-07-30-config-only-repository-plugins.md), not this format package.
## Alternatives considered
**Load a repository's own Cordis entry point.** Rejected because it makes the advertised static format an unrestricted code-loading API, requires repository authors to depend on Harness internals, and duplicates the ordinary SDK/plugin-dependency path.
**Teach generated wrappers to implement skills and MCP directly.** Rejected because copied runtime code would drift from `dsh-skill-local` and `dsh-mcp-client`, especially their provider invalidation, tool synchronization, failure, and teardown contracts.
**Import Harness packages from each generated wrapper.** Rejected because repository packages should not resolve or version the application's internal dependency graph. A Loader builtin supplies one app-owned implementation and keeps generated wrappers import-free.
**Watch prepared repository assets.** Rejected because an exact repository cache generation is immutable. Ref, subdirectory, or configuration changes select a new generation; a second watcher would create an unowned refresh identity.
**Treat MCP connect failures as Loader update failures.** Rejected because the existing MCP client deliberately contains connect failures and exposes no tools. Changing that semantic only for repository sources would create two failure contracts for the same server configuration.
## Consequences
- Existing skill/MCP repositories can add a small `.dsh-plugin/package.json` without relocating their assets or adopting an SDK project.
- Prepared output is deterministic static glue, while the configured repository and its dependency lifecycle remain trusted executable package-manager input rather than a sandbox.
- Multiple repository Plugins coexist through provider names and ordinary MCP server-name uniqueness; duplicate names fail through their existing registries and participate in Loader rollback.
- Cached source edits do not appear live. Another exact source/ref/path/config selection is required.
- Adding another contribution kind requires an explicit format and DSH-owned runtime consumer; it cannot arrive as repository JavaScript by accident.
## Testing
Focused tests prepare skills and MCP metadata, prove the emitted wrapper contains no imports, reject Work IQ-style OAuth fields, map Expo-style HTTP and DataJunction-style stdio plus environment values, and exercise missing variables. A real Loader test mounts a generated wrapper through the registered builtin, reads its skill through `ctx.skills`, removes the Loader entry, and observes provider cleanup. The keyless headless example loads a checked-in prepared wrapper through its real `cordis.yml` and snapshots the repository skill's logged model catalog row.

# Agent Note:静态 repository Plugin 格式
状态:已实现
[English](2026-07-30-static-repository-plugin-format.md) | 中文
## 问题
一个已经包含可复用 skills 或 MCP server 声明的仓库,应当能被独立 Harness 应用使用,而不必先变成 Harness SDK 项目,也不应被迫改写现有布局。常见仓库只需新增一个 `.dsh-plugin` 目录,同时仍可把原有 skills 与 `.mcp.json` 放在仓库其他位置。与此同时,如果把任意仓库入口都当作 Cordis Plugin,就会让每个仓库成为新的无限制运行时扩展表面,并绕过现有的 skill 与 MCP 生命周期所有者。
[Package-manager-native repository cache](2026-07-30-package-manager-native-repository-cache.md) 会准备一个精确 package source,但有意不了解任何 DSH 格式。因此本层需要一种兼容 package manager 的创作格式、确定性的已准备产物,以及在 Loader dispose 和替换期间仍保持事务性的 Cordis 组合。
## 决策
`@deepseek-ai/dsh-repository-plugin` 负责一个受限的 `.dsh-plugin` package 格式,且只允许两类贡献:skill 根和一个通用 `.mcp.json`。Package metadata 使用 `package.json#dsh.skills` 声明相对 skill 根路径,使用 `package.json#dsh.mcpServers` 声明相对 MCP 文档路径;两者至少需要一个。路径可以离开 `.dsh-plugin` 以复用仓库内容,但必须留在包含该 `.dsh-plugin` 的目录之下;因此,一个嵌套且可选择的 Plugin 可以拥有其 package 上方相邻的子树,却不能访问无关宿主路径。
`.dsh-plugin` package 把 `dsh-plugin-prepare` 声明为普通 package-manager `prepare` 脚本。Helper 会校验 metadata 与源码类型,严格解析 `.mcp.json`,把静态资源复制到 `dsh-plugin-assets`,并写入 `dsh-plugin.mjs`。`.mjs` 扩展名避免强迫仓库作者在 package metadata 中设置 `type: module`。生成模块来自固定、无 import 的模板,只包含规范化 manifest、由 manifest 派生的 `inject` 列表(`loader`,加上按声明能力加入的 `skills`/`tools`,使包装 fiber 在其子插件所需服务上门控),以及对 `dsh-repository-plugin` Loader builtin 的委托。准备阶段永远不会发现、转译、打包或保留自定义仓库入口。
加载 DSH package 会以 effect 方式注册该 builtin。生成的包装模块使用 `import.meta.url` 把 builtin 挂载为自己的子级,因此所有贡献都归属于包装 fiber,并在 Loader 移除或回滚时消失。Builtin 会在读取资源前重新校验已准备 manifest 与路径包含关系。它只组合现有实现,而不自行注册 skills 或 MCP 工具。
每份已准备 skill 集合都会挂载 `dsh-skill-local`,使用唯一的 `repository:<package-name>` 提供方名称、仅包含复制后的自定义根,并禁用监视。因此 `dsh-skill-local` 新增两个通用配置字段:`providerName` 和 `includeDefaultRoots`。默认值保持原有单一本地提供方行为;repository 实例设置不同名称并排除项目/用户根,使多个实例既不冲突,也不会重复宿主本地发现。
`.mcp.json` 中的每个 server 都变成一个现有 `dsh-mcp-client` 子级。适配层接受通用根对象 `{ "mcpServers": ... }`;stdio 定义只允许可选的 `type: "stdio"`、`command`、`args` 与 `env`,HTTP 定义只允许 `type: "http"`、`url` 与 `headers`。严格的 `${NAME}` 进程环境变量引用在运行时、cache 准备之后展开;缺失变量会使 Plugin 加载失败。HTTP 映射到 client 的 Streamable HTTP transport,stdio 使用已准备 package 目录作为 `cwd`。只有现有 client 负责连接尝试、失败日志、远端工具同步、工具调用和断开。因此 MCP 连接失败会继续沿用“Plugin 成功但不注册工具”的既有行为,不会被重新分类为 repository 准备或 Loader 失败。
未知 MCP 字段会被拒绝。这里有意排除 OAuth、`auth` 对象、`CLAUDE_PLUGIN_ROOT` 和更广泛的 Claude 兼容契约。Hooks、commands、agents、apps、任意 Cordis 代码、marketplace 和发现同样不受支持。Repository 子目录选择与 GitHub 源配置属于[独立应用集成](../feature/2026-07-30-config-only-repository-plugins.md),而不是本格式 package。
## 考虑过的替代方案
**加载仓库自己的 Cordis 入口。** 拒绝,因为这会把宣传为静态的格式变成无限制代码加载 API,要求仓库作者依赖 Harness 内部实现,并重复普通 SDK/Plugin dependency 路径。
**让生成包装模块直接实现 skills 和 MCP。** 拒绝,因为复制的运行时代码会与 `dsh-skill-local` 和 `dsh-mcp-client` 漂移,尤其是提供方失效、工具同步、失败和 teardown 契约。
**让每个生成包装模块 import Harness package。** 拒绝,因为 repository package 不应解析或锁定应用的内部依赖图。Loader builtin 提供一份由 app 所有的实现,并让生成包装模块保持无 import。
**监视已准备 repository 资源。** 拒绝,因为一个精确 repository cache generation 是不可变的。Ref、子目录或配置变化会选择新 generation;第二套 watcher 会创造一套没有所有者的刷新身份。
**把 MCP 连接失败当作 Loader 更新失败。** 拒绝,因为现有 MCP client 有意收束连接失败并不暴露工具。只对 repository source 改变该语义,会让同一 server 配置拥有两套失败契约。
## 后果
- 现有 skill/MCP 仓库可以新增一个很小的 `.dsh-plugin/package.json`,无需移动资源或采用 SDK 项目。
- 已准备输出是确定性的静态胶水;已配置仓库及其依赖生命周期仍是受信任的可执行 package-manager 输入,而非 sandbox。
- 多个 repository Plugin 通过提供方名称和普通 MCP server-name 唯一性共存;重复名称经现有 registry 失败,并参与 Loader 回滚。
- Cache 内的源码编辑不会实时出现;必须选择另一个精确 source/ref/path/config。
- 新增贡献类型必须提供显式格式和 DSH 自有运行时消费方;它不能意外以 repository JavaScript 形式进入。
## 测试
聚焦测试会准备 skills 与 MCP metadata,证明生成包装模块不含 import,拒绝 Work IQ 风格的 OAuth 字段,映射 Expo 风格 HTTP 与 DataJunction 风格 stdio 及环境变量,并覆盖缺失变量。真实 Loader 测试通过已注册 builtin 挂载生成包装模块,经 `ctx.skills` 读取其 skill,移除 Loader 条目并观察提供方清理。Keyless headless 示例通过真实 `cordis.yml` 加载一份签入的已准备包装模块,并快照 repository skill 写入日志的模型目录行。
