An opencode tile showed only the session name, while Claude Code, codex and
DeepSeek tiles add `· <model>`: opencode declared no `modelDetect`, so its
screen was never read for a model and it is launched without a model param.
opencode draws the model on its composer's agent row, directly above the
box's bottom edge: `┃ Build Big Pickle OpenCode Zen`. Read from its own
1.3.0 source, the row is the agent, the model's name, the provider's name and
`· <variant>` when the model has one, and only colour tells model from
provider. So the field is all of it, exactly what opencode itself shows (the
owner's choice over a short id that only appears after the first reply).
- The pattern anchors on that row sitting directly above the `╹` edge, ends
the field at a double space (where the 200-column layout's sidebar shares
the row), skips the `No provider selected` placeholder, and takes the LAST
such row in the window through a lookahead, so a composer-shaped row the
agent prints higher up can never stand in for it. A test with a forged pair
inside the window fails without the lookahead.
- It reads 8 rows: the home screen puts up to five rows of opencode's own
chrome under the composer (key hints, a tip, the cwd/version row). The
schema's `screenLines` bound goes from 4 to 8, the reader's own cap; the
comment there records why a taller window is only safe with such a pattern.
- A permission prompt or shell mode hides the row; the last model is kept.
Measured against every captured opencode 1.3.0 frame (home screen and in
session, 40/60/120/200 columns, mid-turn and at rest, permission prompt):
the model was read everywhere it is drawn and nowhere else. Live on an
isolated instance from this branch, a restored opencode session published
`displayModel: Big Pickle OpenCode Zen` (source: screen) and its tile header
rendered `oc-home · Big Pickle OpenCode Zen`. The owner's own home-screen pane
on the 1.36.0 beta reads the same.

A pi session showed no model in its tab or tile unless one was passed at
launch, and none at all for the default route. pi draws its model in its
own footer, but its registry entry declared no modelDetect, so the pane
probe never read it.
The footer, from pi 1.1.0's footer code (0.84.4's is the same) and a live
pane (`0.8%/253k (auto) qwen3.8-27b-pi • xhigh`): usage and context
on the left, then at least two spaces and `[(provider) ]<model>`, with
` • <thinking>` for a reasoning model and ` → <routed model>` when
routed. The last two rows are read (an extension status row can sit
below), and the context field picks the stats row out of them.
pi truncates the right side to fit a narrow pane with no ellipsis,
leaving exactly two spaces of padding. A name with nothing after it is
therefore read only with three or more spaces in front, and with two only
when a following ` •`/` →` proves it whole, so a cut-off name is never
shown. `no-model`, pi's placeholder, is rejected.
The read rides the idle confirmation pi gained with its workDetect entry.
Verified on an isolated instance: a fresh pi session published
qwen3.8-27b-pi (source screen) about 8 s after launch.

Every codex tile and tab showed no model, unlike claude and deepseek.
Codex reports its model only in the footer under the composer
(` GPT-6-Luna default · ~/codeman-cases/testcase`), and the registry read
the pane's LAST row for it. Codex 0.162.0 added a hint row under the
footer at rest (` ← for agents · ? for shortcuts`, or ` ? for
shortcuts`), so the last row was always the hint and `displayModel`
stayed null. Measured live on the 1.36.0 beta: the hint is there at rest
and after a turn, and gone while a prompt is being typed (the footer is
the last row again then).
The codex modelDetect window is now two rows, and the footer must be
either the last row or followed by exactly one more two-space-indented
row. Anchoring to the end of the window keeps the guard the one-row rule
had: with the footer hidden, the last two rows are a transcript line and
the `›` composer, so a footer-shaped line the agent printed is not read.
Tests cover both 0.162 hint variants, the typing layout, the hint never
read as a model, and a forged footer-plus-indented pair above the
composer.

The digit rule from 21ae48a5 hid the official DeepSeek ids (`deepseek-chat`,
`deepseek-reasoner` carry no digit), so a session on the official route with
the model field on showed the logo alone (its bundle row pins a provider
alone, so the config had nothing either). It also still misread a folder name
with a digit when every field before it was off.
Now the captured field is rejected when it is what the field can be when it is
NOT the model, and read otherwise:
- capabilities.modelDetect.rejectWords (registry data, single tokens, compared
ignoring case; the schema bounds them and requires a screenLine). dsh lists
every effort id its adapters offer (pi-ai THINKING_LEVELS plus the DeepSeek
adapter's off/low/high/max) and the shipped mode ids, from dsh 0.1.1-rc.2 /
dsh-TUI 0.10.0-beta.1. A mode's drawn label (`plan mode`, `full access`,
CJK) can never be one captured field.
- In the shared screen reader, for every CLI: a field equal to the session's
own working-directory basename is the folder, never the model.
Fixtures: `deepseek-chat` and `deepseek-reasoner` with the model field on are
read; every effort id, `default`, `plan mode`, and the folder name first (with
and without a digit) are not; the live qwen footer still reads `qwen3.8-27b`.
Known gaps, all off by default, are named in stock.ts: a custom mode id drawn
raw, a git branch or a one-word session title first, and the non-compact
footer layout (nothing read there; the route config applies).

dsh-TUI draws the model as its status line's first field only while the
status bar's model field is on (the default). Switched off, the first field
is the reasoning effort (` medium · th-scratch`), else the mode, else the
cwd's basename, and the footer pattern read that as the model, which would
also outrank the route config added in the previous commit.
The captured field must now carry a digit, as a model id does (a version) and
an effort word, a mode name or most folder names do not. A model id without
one (`deepseek-chat`) is not read from the screen and the session falls back
to its route config: silent, never wrong.

displayModel gains a `config` source, ranked below any report from the running
CLI and above the launch model: custom endpoint, then statusline or screen,
then config, then launch, then nothing. The screen still wins whenever it
names a model, since that is what the running TUI uses.
- Registry data: capabilities.modelDetect gains `configResolver`, a NAMED
reader (src/model-config-resolvers.ts), like a launcher profile; dsh names
'deepseek-route' (the reader from the previous commit). `screenLine` becomes
optional; the schema refuses a modelDetect naming nothing, an unknown
reader, or screenLines without a screenLine.
- Session: the reader runs from _withPaneLifecycle's finally, so at every pane
start, attach and relaunch, with the session's own launch config
(legacyConfigForMode) and env (its clamped overrides, then the server's), so
a per-session DSH_HOME is the home read. Async; a read that lands after a
newer one or after the session stopped is dropped; a remote or docker
session reads nothing locally. A change emits displayModelChanged
(broadcast and persist). Not restored after a restart: the next attach
reads it again, and a restored screen value outranks it.

A session header can only name the model a session runs if the server knows
it, so SessionState gains `displayModel: { model, source }`, resolved in a pure
module (src/session-display-model.ts), strongest first:
- custom-endpoint: a Custom Model Endpoint Profile's modelId answers the
session, whatever alias the CLI prints;
- statusline / screen: the newest report from the running CLI itself.
Claude's statusLine exporter already posts model.display_name on every
render; the status-telemetry route now records it (only for a CLI with
capabilities.statusLineTelemetry). A CLI whose registry entry declares the
new capabilities.modelDetect has its footer read off the pane capture the
idle/working probe already takes (no extra tmux call), so an in-session
/model switch is followed at the next transition;
- launch: the model the session was launched with (claude's --model or the
app-wide default, another CLI's <cli>Config.model), read where the registry
says the model param lives;
- nothing known: no field, never a placeholder.
modelDetect is registry data, measured on live panes: dsh-TUI's status line
on the row under its composer (qwen3.8-27b on the owner's route) and codex's
`<model> <effort> ·` footer on its last row. Both anchor on chrome only that
CLI draws, over the last rows of the screen only; a transcript line shaped like
the footer is never taken (fixture tests). The pattern goes through
compileVersionRegex() with exactly one capture group, checked at load time.
An unreadable or covered footer keeps the last model (unlike the watching
label: a model does not stop running when something covers its row). Model
text is untrusted: escape sequences and control characters are stripped and it
is capped at 64 characters. A change emits displayModelChanged, broadcast
(session:updated) and persisted; a restart restores a CLI-reported model until
the next report.
