An overlay pair switches the acp demo's packChunks on; the authored fixture
(text-turn's recording refreshed through that overlay) commits a session.jsonl
whose reasoning run persists as one packed reasoning-chunks row while the
short text run stays verbatim. Keyless replay proves the packed fixture
derives the same model script (fixture reading is layout-blind) and the
re-persisted log packs identically — the transcript surface of the packChunks
switch is now pinned without touching any existing golden.
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.

The acp escalation smoke advertises the shipped deepseek-v4-pro; the
workspace-context e2e asserts the per-candidate scope key. The PTY harness
drops COLORTERM (deterministic banner) and gains configArgs/prepare/inspect
for the dsh CLI scenarios.
Replace /mode [name] with same-named no-argument commands such as /plan. Update the TUI and ACP snapshots, and validate mode names against command syntax.
The built-bin fail-loud test needs the TTY refusal before Loader boot (a
compose-time throw is logged per-entry, not rethrown); the PTY driver drops
COLORTERM so a developer's truecolor shell cannot flip the banner to the
gradient path mid-assertion; the scripted fixture persists raw JSONL so the
smoke's system-prompt inspection can read the log.
- 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)
Make todo_write opt-in for the tui-agent example (disabled by default; TUI
still renders plans when the tool is loaded). Both enabled and disabled cases
covered by tests.
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.

The master merge (windows-runtime) shifted TuiConfig's source line without
regenerating docs/config-catalog.md, and its Windows stdout pin for
workspace-edit was recorded on master without dsh-mode — the session/new
result lacked the modes advertisement and the command list lacked /mode.
Both lines carry no filesystem paths, so the POSIX pin's bytes are correct
on Windows too; graft them verbatim.
The remaining red CI on this PR head (windows coverage/static LSP failures,
the web-search live e2e) reproduces on master's own HEAD 32ccc405b and is
not a branch regression.
Four ds-review-bot findings:
- examples/tui-agent composed dsh-mode without the now-required
modes.plan.section, so the TUI leaf failed at Loader startup (the keyless
smoke only asserts the banner and missed it); graft the same deployment
plan instructions the ACP leaf carries.
- The prompt-submit and turn-continuation flushes ran before next(), so a
session/set_mode arriving while a downstream async listener (the shipped
hooks listeners' shape) awaited applied one request late; both listeners
now prepend and flush after next(), matching the request-error wrapper,
with a regression test pinning the ordering.
- An HMR unload during the exit_plan_mode review let a later approval write
into the disposed service and claim an exit whose flush could never land;
the execute path now checks the fiber lifetime after the await and fails
the call (the mode stays plan; the model re-presents).
- resolveConfig accepted empty/untrimmed mode names that list()/ACP then
advertised while the package invariant rejected their selection,
desynchronizing the picker; names are validated non-empty and trimmed at
load, the same shape the invariant enforces.
