- 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).
A TUI run against an unreachable endpoint failed with only 'fetch failed':
undici wraps transport failures in a bare TypeError whose diagnosis lives
on .cause, and every diagnostic seam rendered only error.message. The
readline front door additionally rendered failed turns as pure silence.
- dsh-llm: new errorChain(value) renders the full cause chain and
AggregateError members with circular/hostile-coercion containment.
- llm-deepseek: pre-response transport failures throw LlmError('NETWORK')
naming the endpoint and chaining the fetch TypeError; aborts keep their
DOMException so the loop still classifies them as cancellation.
- agent-loop: durable turn/end error messages and logger warnings render
through errorChain; local renderThrown copies removed.
- ui-stdio: failure turn/end reasons now render ([turn failed <code>],
[turn aborted], [turn rejected], output-token-limit); startup-failure
logs use errorChain.
- ui-tui: agent/error notices and the startup-failure line use errorChain.
