* refactor(session): ask the shared supersession predicate at the older sites
``_check_cancelled`` and ``_compaction_event`` predate
``_generation_superseded`` and each carried its own inline copy of the
formula, so the drift the helper exists to prevent had two live places
to start from.
Both are behaviour-identical today. What the pin protects is the
generation-0 convention: a bare ``!=`` reads a direct seam caller as an
orphan, which would raise a cancel on a live turn and stamp a live
compaction superseded — suppressing the end notice, so an operator
watching a real compaction fail would be told nothing at all.
* fix(session): render a wire-prep fault's cause class, never its message
Every other branch of the fatal formatter tails the backend's own
diagnostic text, which is what the operator needs. This branch is
different in kind: ``prepare_wire`` is our lowering over the session's
stored history, so its exception message can quote that history — and
the formatted string is both shown to the operator and persisted to
``last_error``, which a coordinating agent reads. ``redact_credentials``
is a best-effort regex by its own docstring, so it is no floor for
arbitrary conversation text.
The cause's class still identifies the fault, the guidance is unchanged,
and the debug traceback logged in the same function localizes the raise
site.
* feat(console): surface the server-side reasoning parser capability
The inline think-tag scan is a fallback for inference servers with no
reasoning parser, and for misconfigured ones. An operator running vLLM
or llama.cpp with a parser configured had no way to say so from the
model shelf — ``server_parses_reasoning`` was reachable only by hand
editing the raw capabilities JSON, and it defaults to off, so the scan
stays on and both channels run at once.
The tile test is a general invariant rather than a single-key pin: every
tile key must render a checkbox, carry a default, and — where the key is
a ``ModelCapabilities`` field — agree with the dataclass. The matrix is
a hand-maintained mirror, so it drifts silently otherwise.
* fix(model_turn): a wire-prep wrapper carries the cause's class, not its text
Withholding the message in the fatal formatter was not enough. The
wrapper was built as ``WirePreparationError(str(prep_err))``, so
``str(exc)`` IS the cause's message — and the interactive retry arm
renders exactly that into the dashboard SSE, one line after the formatter
emitted the redacted version. ``sanitize_error_text`` is no floor there:
it returns arbitrary stored-history text unchanged.
Fixing the exception rather than the one consumer closes every caller
that stringifies it, now and later. The message still rides
``__cause__`` for tracebacks and debug logs.
* fix(console): coerce lifted capability values the way the backend does
The tile lift used bare ``!!``, but the capabilities dict is hand-edited
JSON: a stored string "false" is truthy to JS while
``apply_capability_overrides`` reads it as False. Opening such a row
rendered the tile CHECKED and saving persisted boolean true — inverting
the capability without the operator touching it. For
``server_parses_reasoning`` that silently disables the inline tag scan,
the exact typo model_turn's comment already warns about, and this key had
just been lifted into the matrix.
``_capBool`` mirrors the backend's spelling table; a value the backend
would not coerce stays in the raw JSON rather than being rewritten, which
is the policy the modal already applies to thinking_mode. Cases are
generated from the Python table and executed under node, so a spelling
added on one side fails here.
Also tightens two pins the tile test left open: the checkbox must render
inside the container the JS actually queries, and a tile key that is not
a capability field is exempted by NAME rather than by a blanket hasattr,
which was swallowing the consistent-rename case.
