The smoke's inline Python pty driver only ran on POSIX (no termios on
Windows). Rebuild every scenario — banner sweep, scripted conversation with
model switch, /skill:, Code Mode overlay, resume failure, and the dsh CLI
suite (default boot, personal overlay, invalid overlay, --resume flag,
source-path prompt) — as marker-gated action lists on pty-harness.ts, which
drives ConPTY via node-pty on Windows and the Python driver elsewhere. The
harness gains configArgs (bins with built-in default configs), prepare
(workspace seeding), and inspect (post-run log assertions); examples/
declares the session-title provider the shipped cordis.yml now mounts.
Master's log-backed session-title capability already titles sessions durably
(deterministic fallback in the spine, optional model providers). Remove the
TUI's own autoTitle generation — the latch, prompt, cap, and llm stream call —
and keep the terminal rename: the TUI folds the logged title on mount and sets
'<session title> — <configured title>' on every accepted session/title event.
The tui-agent example and the scripted PTY fixture mount
session-title-first-message-llm so titles stay model-made; the scripted
adapter's tool-less branch now answers that provider's auxiliary request.

- acp/headless whole-config snapshot patches restate persistenceCompression:
none so raw JSONL fixtures stay harvestable, and re-pin the recorded
deepseek-v4-flash where the shipped config moved to pro
- depth-two overlay gains the app-config re-pin master's other overlays carry
- headless-agent stays on flash: goal/ralph overlays include it via a nested
include, which a config patch cannot reach to re-pin
- workspace-context scenarios re-record their session fixtures for the
per-candidate scope keys and both-siblings loading; acp session fixtures
otherwise return to master's (session/title + delegationDepth events)
Post-rebase reconciliation of the two TUI lines that evolved in parallel:
- header subtitle prefers the latest logged session title over the configured
welcome; the process-local auto-title owns the whole terminal title while a
logged session/title still wins through the suffixed form
- footer keeps staging's model/cwd/usage/cache layout and gains master's
context-percent segment; per-step usage dedup carries cache buckets
- test harness only stubs the llm catalog when the test did not mount the
real LlmService, and defaults the TUI clock to the real Date.now
- the plugin-shaped /reload test composes commands+llm like the shipped app
Squashes feat/tui-cache-hit-rate and feat/tui-verbose-status: the footer
shows cache hit rate and the running status line reports turn phase with
elapsed timing.
Squashes three linearized steps (feat/tui-startup, feat/banner-reveal,
feat/remove-banner): the banner experiment converged on removing the
startup banner entirely; later commits restore it borderless and add the
brand gradient.
Squash of the linearized fix/tui-color-scheme-v2 merge and the follow-up
catalog regeneration. Renders error cause chains at every diagnostic seam
(origin/fetch-failed-diagnostics) and adds color scheme detection with a
light-terminal palette.
Delete packages/ui/stdio and examples/repl-agent; rename stdio-demo to
@deepseek-ai/dsh-tui-demo (TUI-only, refuses pipes before Loader boot).
tui-agent owns the coding composition inline; echo-agent and the CI demo
smoke move to the one-shot cli-demo bin, which gains -p/--prompt. The
UI-independent with-key e2es move verbatim to tui-agent. SDK wizard's
'stdio' interface becomes 'tui'. PTY testing stays confined to TUI
surfaces; all other subprocess tests ride pipes.

Resolve conflicts:
- packages/ui/tui/src/index.ts: keep the color-scheme detection block; drop the
obsolete static autocomplete list (master moved to refreshCommandAutocomplete).
- docs/config-catalog.md: regenerate (tui Config source line shifted to :104).
The color-scheme detection block left packages/ui/tui/src/index.ts below
the 100% per-file coverage gate on three counts: the .then callback's
`scheme === undefined` branch was reachable only via the 2s query
timeout, the .catch only via a query-write failure, and the
`editor.borderColor` assignment inside applyColorScheme was dead code —
the next line's setStatus() immediately reassigns editor.borderColor.
Register the scheme listener before firing the startup query so the
query's own reply is delivered through the listener (the same path as
later theme switches), which removes the redundant .then re-application
and its uncoverable undefined branch, and closes the theoretical window
where a synchronous reply lands before the listener exists. Drop the
dead editor.borderColor line. Cover the rest: a same-scheme report
(early return) and a terminal that throws on the query write (the
swallowed .catch).
