Rename the tool-presentation transport from code-mode to ptc everywhere
that is not written into session logs: the mode config value becomes 'ptc',
the preset directory/id becomes ptc, the demo becomes demo:ptc, the
dispatch waterfall becomes tools/ptc-dispatch-log (types PtcDispatch*), the
prompt rule becomes tools:ptc-only, source/test files become ptc.ts etc.,
and prose says PTC mode / PTC 模式. The session-persistent vocabulary
(durable events tool/code-dispatch*, logged plugin name tools-code-mode,
sub-call id segment :code:) intentionally stays and moves in the stacked
persistence PR, which is blocked until the SESSION_FORMAT_VERSION v0→v1
migration lands with it. run_code, its code parameter, CodeSdkLanguage,
CodeRunFailedError, the dsh-code-runtime family, third-party codex names,
and frozen archived notes keep their names.
Discovery proved only that a composition parsed, so a preset naming a
package a later rename took away kept a healthy card and its place in
every picker until a person switched to it. It now resolves each row it
can prove will start, reading the package off disk and falling back to
the resolver only for names that look absent — the resolver costs a
synchronous hooks-thread round-trip under the source launch's tsx hook,
which the walk avoids for every row it clears.
The mount diagnostic followed `AggregateError.errors` but never a cause,
so a group that failed on two rows named neither. It now follows a cause
that carries more than its own message.
A refused switch left the chip's label snapping back with no account of
why, which is the only account there can be for a preset that resolves
and then refuses. It announces through the shared Toast, which gained a
caller-set hold for a cause that names packages and rows.
