The agent-default-model refactor moved the headless runner off the
api-proxy create path onto a direct agents.create, which silently dropped
the preset composition the stack had put on every dsh run session: the
header lost its agentPreset and the agent ran on the host composition
alone. Resolve the default preset up front (optional service — a roster-
less composition keeps the pre-preset behavior), record it on the header,
and mount it in setup where a broken composition still fails the run.
- Clone patch lists per generation (boot + composeLive): the include pushes
insert rows by reference and mutates them in place, so a reused object
baked user overrides into bundle rows and removal could not revert; the
built-bin hot-reload e2e now asserts an override AND its removal reverting.
- The headless runner awaits Loader settlement before prompting (its inject
gate covers only apiProxy/httpServer) and abandons cleanly when the tree
died during the wait.
- healProfilesModuleFallback walks the app's full dependency+peer closure:
out-of-tree plugins import seam packages (dsh-compact, dsh-subprocess, ...)
that only implementations reach, and peers are how seams are declared.
- Profile init writes pnpm-workspace.yaml (nodeLinker: hoisted), not .npmrc
— pnpm >=10 reads settings from the workspace manifest.
- Web dumps reject boot-only flags instead of printing a tree that differs
from the same invocation's boot; --port validates at the flag;
--dump-default-config no longer parses the (possibly broken) user layer;
trustedHosts flag derivation merges over the composed value instead of
replacing it; web-runtime gains surfaceContext (headless disables the GUI
prompt/bash-vars the old -p never mounted); 'node_modules' is a reserved
profile name; plugin-warning names the recovery step; client AGENTS.md
registration surfaces point at the web-app bundle.
- Ship session-reference/tmux-context/tool-ask-user as app dependencies for
terminal front-door patch layers (turtle-ui), same stance as mcp-client.
Profile bundles are npm packages declaring dsh.patch in their manifest:
dsh-base carries the former base.cordis.yml rows as one insert over the empty
profile root; dsh-web-app carries the web overlay plus a runtime glue plugin
owning what used to be launcher code (frontend dist resolution via
frontend-static, the web-surface prompt section, bash runtime variables, the
readiness-gated URL line); dsh-headless carries the one-shot runner driving a
task turn through the in-process API carrier under the launcher-provided
ctx.headlessIo seam.
