Add the activity capability seam: ctx.activities is a pure observation
plane where long-running work (background bash/pwsh, workflow runs) opens a
handle, appends transient output into a byte-offset ring buffer, and settles
exactly once. Nothing model-visible changes: reads are non-consuming and
lossy-by-design (absolute UTF-8 offsets survive eviction and report gaps),
correlation carries {callId, jobId}, and visibility is owner-fenced like jobs.
The seam is strictly optional. Producers tap it through ctx.get('activities')
and contain every observation failure, so an unregistered or broken registry
never affects the underlying job (proven by broken-registry tests).
Ship the full path in one change:
- @deepseek-ai/dsh-activity: Service Definition, pumpActivityOutput pull
substrate, invariant companion; dsh-activity-local: ring-buffer provider
with retention config and owner cleanup.
- shell: ShellProcess.observed exposes non-consuming stdout/stderr readers;
tool-bash/tool-pwsh mirror background jobs into activities.
- tool-workflow: phase/log/agent lines mirrored as a workflow activity.
- api-activity-controller: Typert Remote control (roster baseline+buckets)
and observe (opened/output/status frames, coalesced and byte-capped)
streams plus the client feed service with reference-counted observation.
- ui-activity: session-header action rendering live output through
TerminalBlock, which now shows output while a command is still running.
Docs: activity subsystem page, architecture row, regenerated catalogs, and
the Agent Note (2026-08-24-activity-observation-seam), all bilingual. A
keyless web e2e replays a real run_in_background stream to ARIA goldens.
@deepseek-ai/dsh-base
English | 中文
The shared dsh core as a profile bundle: cordis.patch.yml inserts every base plugin row — model adapters, the shared agent-default-model selection, tools, persistence, policy, settings/credentials, telemetry, and the core spawn/fork subagent providers — over the empty profile root, as the first layer of each base-backed profile's dsh.profile.bundles list. The standalone sdk-minimal profile deliberately does not include this bundle. The optional Codex and Claude Code providers stay outside this package and its production dependency closure; a Profile installs either product provider Bundle only when needed. The default @deepseek-ai/dsh production closure therefore includes neither product provider, the Claude Agent SDK, nor the Codex wrapper and platform payloads. Later bundle layers (e.g. dsh-web-app) and the user's profile cordis.patch.yml override these rows by id; a patch replaces a row's whole config, so mode-specific values live in mode bundles, not here. The package has no runtime API; the profile composer resolves the patch through the dsh.bundle.patch manifest field, never through code.
The base module-HMR row is disabled. A profile with a tested source-module reload lifecycle enables that row explicitly; patchReload: live config watching is independent and uses the launcher's watch-only fallback while module HMR remains disabled.
The patch gates both shell stacks by platform on its own rows: bash-sandbox/tool-bash carry disabled: !!js process.platform === 'win32' (bash has no Windows runner), and their twins pwsh-sandbox/tool-pwsh mount on win32 only with the inverted expression — one shared patch file, exactly one shell stack per host. The permission surface stays exactly as on POSIX: sandbox/sandbox-policy enforce the file-effect policy through the Windows ACL restricted-token runner (the win32 chain of dsh-sandbox-local → @deepseek-ai/dsh-sandbox-windows-acl), the permission switcher and the approval service run unchanged, and fs-sandbox keeps fencing ctx.fs writes — mounting dsh-fs-local alongside it would double-register ctx.fs and fail the load. A Windows host that prefers the unconfined local pwsh executor or full access overrides these rows through its profile or home cordis.patch.yml (the bash-restore recipe must be complete: disable pwsh-sandbox/tool-pwsh AND re-enable bash-sandbox/tool-bash — both executor families register the same bash service, so an incomplete recipe fails loud at load). POSIX hosts see the pwsh rows disabled.
The row set and its rationale are documented inline in the patch file; the generated composition graph renders it.
Model Experience
Indirectly, through the inserted rows: this bundle selects the shipped persona-less prompt base, tool set, and DeepSeek adapter that mode bundles specialize, and contributes no model-visible text of its own.
KV Cache effect
None directly; each inserted row's package owns its effect.
Known Limitations and Deferred Work
- A patch replaces whole row configs — profile overrides must restate every field a row keeps; there is no deep-merge layer.
- The Windows temp grant is a private per-session subdirectory —
workspace-writeconfines writes to the workspace plus the session's own temp subdirectory (<temp>\dsh-<hash>, TMP/TEMP rewritten for confined children);read-onlygrants nothing. See@deepseek-ai/dsh-sandbox-windows-acl.
