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.
Render reconstructable system prompts at each request-series boundary, preserve series declarations through pre-step wrappers, and keep the presentation and replay snapshots aligned across clients.
The turn-error Definition suppressed its node permanently once the owning
turn carried any llm/retry event — a rule from the retired model where a
retry opened a new numbered turn. Retries now run inside the failing turn,
so the suppression hid exactly the exhausted terminal failure it existed
to defer to: spending every transient retry left the conversation with a
neutral collapsed retry row and no error row at all.
Delete the suppression: turn-error matches only turn/start and error-reason
turn/end, and renders whenever its turn recorded a terminal error; the
settled retry chain renders beside it through the separate model-retry
node. The Definition suite now asserts the exhausted-retry error node in
full history, tail-only windows, and after prepending the chain, and a new
keyless live e2e scenario exhausts a scenario-owned two-retry policy and
pins the terminal error row beside the settled retry row (the scaffold
gains replayRetryPolicy so exhaustion runs in milliseconds).
Both stale notes are corrected to the same-turn retry reality, and the new
bug-fix note owns the removal rationale.
