feat(deepseek): read the model a dsh session's TUI route config pins
A DeepSeek session whose screen names no model (dsh-TUI's status bar model field off, or not drawn yet) can still name the model its route config pins (owner request). src/deepseek-route-config.ts resolves it the way dsh and dsh-TUI 0.10.0-beta.1 do, for the session's profile (else the one the launch boots) under the session's dsh home: - dsh composes a profile from patch layers: the bundles, then profiles/<profile>/cordis.patch.yml, then $DSH_HOME/cordis.patch.yml (which outranks it). A patch's `config` replaces the dsh-tui row's whole config, a `name` mismatch skips it, `disabled` turns the row off. - dsh-TUI takes its route from that config only when it names BOTH provider and model (modelRoute.js); anything less falls back to state the config does not hold, so the answer is nothing. The bundle row pins a provider alone by design and is not read (it resolves outside the dsh home); settings.yaml's agent-default-model is the headless default and is never read. - Any doubt answers nothing: a profile without dsh-TUI, a half-pinned route, an unreadable or oversized layer, a symlink out of the dsh home, a mount that does not answer, a file beyond a narrow strict YAML subset (no dependency added: plain keys, single-line string scalars for the values it needs; tags, anchors, aliases, merge keys, multi-line scalars, flow or block-scalar config, duplicate keys, typed scalars, a second document, or a nested row re-defining dsh-tui all answer null). - Bounded and read-only: every path is probed with probePathKind() first, read async with a 64 KiB cap, and must realpath inside the dsh home. Only the model id leaves the module. The default-profile inventory reuses the resolver's classification through a new pure deepSeekProfileFromManifest(), read with the same bounded rules. Not wired to sessions yet; the next commit does. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

/**
|
||||||
|
* @fileoverview The model a DeepSeek Harness (`dsh`) session's TUI is configured to
|
||||||
|
* use, read from its route config, for a session header whose screen names no model
|
||||||
|
* yet (the status bar's model field switched off, or not drawn yet). See
|
||||||
|
* `SessionState.displayModel` (src/session-display-model.ts): the screen still wins
|
||||||
|
* whenever it names a model, since it is what the running TUI actually uses.
|
||||||
|
*
|
||||||
|
* ## How dsh-TUI resolves its route (dsh 0.1.1-rc.2, dsh-TUI 0.10.0-beta.1)
|
||||||
|
*
|
||||||
|
* A profile is a stack of loader patch layers over an empty root, in this order
|
||||||
|
* (`@deepseek-ai/dsh` profile-boot): every bundle's patch layer, the profile's own
|
||||||
|
* `$DSH_HOME/profiles/<profile>/cordis.patch.yml`, the home-level
|
||||||
|
* `$DSH_HOME/cordis.patch.yml` (it outranks the profile layer), then `--patch`
|
||||||
|
* overlays (Codeman passes none). A patch targets a row by `id`; one whose `name`
|
||||||
|
* does not match the row's is skipped; every other key REPLACES the row's field
|
||||||
|
* whole (`applyEntryPatches`), so the last layer carrying `config` for the `dsh-tui`
|
||||||
|
* row defines all of it.
|
||||||
|
*
|
||||||
|
* dsh-TUI then takes its model route from that config only when it names BOTH
|
||||||
|
* `provider` and `model` (`lib/types/modelRoute.js`, issue #67). Anything less is
|
||||||
|
* dropped whole and the TUI falls back to the persisted `/model` choice, then to its
|
||||||
|
* own default: neither is in the config, so neither is answered here. The bundle's
|
||||||
|
* own row pins `provider: deepseek-official` alone, by design, so only the two user
|
||||||
|
* layers can pin a route; the bundle layers are not read (they resolve through the dsh
|
||||||
|
* installation, outside the dsh home). `settings.yaml`'s `agent-default-model` is the
|
||||||
|
* HEADLESS default, not the TUI's, and is never read.
|
||||||
|
*
|
||||||
|
* ## Answer nothing rather than a guess
|
||||||
|
*
|
||||||
|
* Every doubt answers null: a profile that does not compose dsh-TUI, a half-pinned
|
||||||
|
* route, a layer that cannot be read (unreadable, a symlink out of the dsh home, too
|
||||||
|
* big, a mount that does not answer), and a file this reader does not fully
|
||||||
|
* understand. The YAML reader below is deliberately narrow (the repo carries no YAML
|
||||||
|
* dependency): a top-level block sequence of patch items, plain keys, single-line
|
||||||
|
* plain or quoted string scalars for the values it needs, and null for anything else
|
||||||
|
* that could change the answer (an anchor, alias or tag such as `!!js` on such a value,
|
||||||
|
* a merge key, a multi-line scalar, flow or block-scalar config, duplicate keys, a
|
||||||
|
* scalar YAML would type as a number, boolean or null, a second document, a nested
|
||||||
|
* row redefining dsh-TUI).
|
||||||
|
*
|
||||||
|
* ## Never block, never write, never leak
|
||||||
|
*
|
||||||
|
* Every path is probed with the bounded `probePathKind()` before it is touched, read
|
||||||
|
* asynchronously with a size cap, and must resolve (realpath) inside the dsh home.
|
||||||
|
* Nothing is written. Only the model id leaves this module: never the provider, a
|
||||||
|
* base URL, a key or any other config value.
|
||||||
|
*
|
||||||
|
* Tests: `test/deepseek-route-config.test.ts`.
|
||||||
|
*

||||||
