Document dsh as the only application launcher across architecture, CLI, SDK, app-boot, Python package, contributor, tutorial, and example references. Explain explicit home selection, profile and patch precedence, persistent external plugin installation, the Node-free runtime path, and the absence of complete-config or ~/.dsh fallbacks.
Record the Python profile-runtime decision and update the active naming, installed-wheel, and SEA packaging notes with precise supersession. Regenerate the configuration catalog and module graph after deleting the carrier, update both reviewed languages and pairing records, and classify the retained standalone Cordis files as lower-level test fixtures rather than launch interfaces.
Migrate the packaged-runtime smoke inventory from complete Cordis trees to the sdk profile plus ordered patches. Preserve the focused minimal and advanced behaviors, update the generated durable snapshots for explicit permission events and the smaller RunResult, and keep worker, MCP, ripgrep, PTY/editor, direct JSON-RPC, and real-provider coverage.
Add an installed-only external bundle scenario that invokes the wheel's dsh plugin command with a local file package, verifies profile manifest reconciliation, imports @deepseek-ai/cordis as a peer, asserts the packaged proxy returns the exact host Context instance, and proves its system-prompt contribution reaches the model. Migrate the repository source e2e and runnable minimal example to the same profile grammar.
Replace complete-config, session_root, runtime-bin, bridge-bin, and public argv override options with dsh_bin, profile, ordered patches, and dsh_home. Resolve executable/home/patch/cwd paths before spawn, select the sdk profile by default, and fail before launch unless dsh_home or non-empty DSH_HOME is explicit; Python never inherits ~/.dsh silently.
Remove Python-owned DSH_CORDIS_CONFIG, DSH_SESSION_ROOT, and DSH_CWD injection and drop session_root from RunResult. Keep arbitrary argv only as an underscore-prefixed fake-runtime adapter, retain provider/model/token and process controls, and append subprocess stderr to initialization JSON-RPC errors so profile boot failures name their actual plugin cause. Unit and carrier tests cover both exe and Node modes.
Make the zero-code dsh-python-runtime-closure depend on the real @deepseek-ai/dsh application and every required profile peer, then package apps/cli's built bin instead of the deleted Python carrier. Rename executables to deepseek-harness-sdk-runtime-<platform>-<arch>, update wheel/platform/build workflow discovery, and install a Python dsh console command that requires explicit DSH_HOME before exec.
Include profile, bundle, preset, native addon, and shared-library assets needed by the full CLI. Remove the checked-in default cordis.yml and preserve the existing wheel distribution names, Python module names, sidecar validation, and wire identity. Runtime resolution and release tests pin the new artifacts and dev Node carrier.
Teach the profile installation fallback to use normal symlinks under Node and real ESM proxy packages under pkg. Each proxy records the source package version, mirrors its explicit runtime subpath exports, and re-exports the virtual /snapshot URLs, so built-in Loader rows and external plugin peers resolve one shared Cordis/module instance from an on-disk profile.
Keep proxy healing idempotent, reject foreign real directories, cover root and subpath imports in packaged mode, and expand AggregateError startup diagnostics so concurrent Loader failures retain their individual import causes. This is the reusable packaged-profile mechanism; Python-specific artifact wiring remains in the next commit.
Delete @deepseek-ai/dsh-sdk-python-runtime and its packaged-bin entry now that Python uses the repository's dsh application launcher. Remove the package's project reference, Knip entry, workspace-policy exception, executable allowlist entry, and README-model classification together so no tooling preserves the old exception.
This commit is deliberately mechanical: it removes the obsolete package and gate accommodations without introducing the replacement launch behavior. The following commits add the packaged dsh runtime and Python profile API, keeping the architecture change separate from deletion noise.
The read-image-reencode lane feeds a 16-bit gradient PNG through the
shipped app: pass-through is impossible, the master converts down the
opaque JPEG ladder, and the 640,000-pixel request budget re-encodes a
downscaled request version — the projection the byte-identical tiny
fixtures never exercised.
Master dimensions move from a 2048 long-edge rule to a total-pixel
budget (normalizedImageMaxPixels, default 2048x2048) with an 8192
long-edge cap, so extreme aspect ratios keep short-edge resolution.
The shared quality ladder and lazy execution move to encoding.ts,
review-round doc fixes land across attachment and llm packages, and
the superseded facts in the unified-image-pipeline note now describe
the shipped routing.
Delete the 5-bit colour-count classifier and palette PNG branch that
misrouted high-frequency photographic JPEGs (issue #2885 images 23/24)
into an encoder 100x slower with 4x larger output. Both normalization
and request-image encoding now route by the decoded alpha fact alone:
opaque sources down a JPEG ladder and alpha sources down a WebP
effort-0 ladder, each at qualities 85/75/60. Byte budgets become ladder
targets: the downscale retry loop is gone and a ladder-exhausted encode
keeps its smallest output, while provider byte caps stay enforced at
the transmitting route. Request transforms move to request-image-v5.
The worker-preview pack landed on master declaring dsh.configTrees
against apps/cli/config/agent-presets, which this branch moved into
packages/preset/agent-presets/presets. The VFS mount and the worker-side
roster patch keep their paths; only the source directory follows the
move.
