Address review on PR #36998: the inline ri.<service>..<ns>. stripper in
_get_status_bar_snapshot was a one-off heuristic that:
* lived in cli.py with no shared call site, so the switch-confirmation
banner ("✓ Model switched: ri.language-model-service..…") and the
[Note: model was just switched from … to …] system-prompt nudge still
printed the full opaque RID — exactly what the screenshot reported;
* split on '..' and re-split on '.', which would mis-handle any RID
whose namespace token isn't a single dotted segment.
Refactor:
* New module-level helper hermes_cli.model_switch.format_model_for_display
matches on a startswith() allow-list (_OPAQUE_MODEL_PREFIXES) and
returns the trailing slug. Falls through to the original string for
every non-Palantir id, so HF paths (meta-llama/Llama-3.3-70B-Instruct),
plain Claude/GPT names, .gguf paths, and aliased ids are untouched.
Allow-list is extensible — add a prefix tuple entry for future
proxies that wrap real names in a namespace (Bedrock ARNs are
already covered by the slash-split fallback and have a different shape).
* _get_status_bar_snapshot() now delegates to the shared helper after
the reverse-alias miss (so configured aliases still win over the
helper output).
* cli.py::_handle_model_command — both confirmation-print blocks
(~7720 and ~7975) now run result.new_model AND old_model through
the formatter before they hit _cprint() and the
_pending_model_switch_note text.
* gateway/run.py model-switch handler (~10915) — same treatment for
_pending_model_notes[_session_key] and the
t('gateway.model.switched', model=…) confirmation line returned to
the gateway client.
The formatter is DISPLAY-ONLY. The session_model_overrides map,
ModelSwitchResult.new_model, persistence to config.yaml, alias lookups,
and every wire call still carry the full opaque RID — Palantir's API
requires it.
Verification: unit reproducer covers (a) all four Palantir model RIDs
from this user's config stripped to the trailing slug, (b) plain
model names (claude-4-7-opus-20260101, gpt-5.4, HF paths, empty
string) passed through unchanged, (c) prefix-only edge preserved
(no infinite-loop / empty-output regression).
Refs: PR #36998 review feedback; screenshot showed model banner still
printing the long RID after the original status-bar-only fix landed.
