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.
Resolve packaged profile proxies with Node ESM import conditions from each package installation, and fail loud when an explicit runtime export or legacy main entry is missing. Serialize the shared profile fallback under the existing cross-process writer lock so concurrent dsh processes cannot observe partial proxies; either carrier now replaces the other carrier’s managed entry without manual cleanup.
Give Python initialize its own 10-second default bound and name the selected profile in timeout diagnostics, while leaving ordinary agent turns unbounded by default. Package the dynamically resolved web frontend and skill-badge assets so the runtime wheel’s normal dsh profiles do not depend on pkg static-discovery accidents.
Rewrite the root launch rule and every active stale SDK-runtime note to the shipped dsh profile architecture in both languages. Focused tests prove import-only and transitive package exports, lock contention, cross-carrier transitions, missing-entry failures, asset inventory, and bounded initialization.
Document dsh as the only application launcher across architecture, CLI, SDK, app-boot, Python package, contributor, tutorial, and example references. Explain explicit home selection, profile and patch precedence, persistent external plugin installation, the Node-free runtime path, and the absence of complete-config or ~/.dsh fallbacks.
Record the Python profile-runtime decision and update the active naming, installed-wheel, and SEA packaging notes with precise supersession. Regenerate the configuration catalog and module graph after deleting the carrier, update both reviewed languages and pairing records, and classify the retained standalone Cordis files as lower-level test fixtures rather than launch interfaces.
Add verify-application-entrypoints to the top-level gate graph. It inventories executable sources and package bins across apps, packages, and examples; rejects unclassified launchers including root-level js/mjs/cjs/ts files; and permits only the dsh CLI plus the explicitly private Python runtime carrier exception.
Update repository, architecture, CLI, and naming records to state the same rule: Node consumers select a dsh profile instead of invoking application-package bins, and no compatibility aliases remain. Fixtures prove both allowed classifications and representative escape attempts, making the architectural rule mechanically enforceable.
Some credentials cannot be configured, only obtained: getting one means
a conversation — open this page, paste that code, pick an account. The
new seam owns that conversation and the one-attempt-per-key lifecycle,
and never the protocol, so a second authorization protocol arrives as
another flow rather than as another seam.
A flow is registered under the CredentialKey it writes, which is also
how the seam knows which plugin answers for the format inside that
record. The flow owns the write: run() resolving means the record is
already committed through ctx.credentials, and the seam confirms it.
That keeps a library persisting through its own store adapter the
single writer instead of being copied back out and written twice.
The interaction travels with the request rather than a registry,
because whoever starts an authorization is the one who can talk to the
human about it. A request already withdrawn never claims the key and
never starts the flow — relying on each flow to check its signal before
the first await would let one that does not hang holding the key.
The Python lane never compared what the minimal composition shows the
model: the mock model only asserted system-role messages, and the
advanced snapshot tokenizes the assembled system prompt and tool
schemas.
The sdk-minimal scenario now records model-visible.json — every model
request's advertised tool schemas verbatim and its message list, with
system and user text kept and assistant/tool payloads reduced to call
identity so the expected output replays on macOS and Linux. It excludes
the dynamic runtime-context snapshot, which the same composition emits
on macOS and not on Linux (#2488).
AGENTS.md and the testing policy name both SDKs as independent
projections of the agent loop, session lifecycle, and SessionEventMap.
The Windows platform layer disables tool-bash and inserts the pwsh stack, but the shipped presets each mount a tool-bash row that re-enabled the tool on win32 — the session had both a PowerShell-backed bash tool and tool-pwsh, silently, because no spec pinned the composed preset layer.
The Loader now evaluates a disabled: !!js expression against the loader context at every mount decision; disabled is the only interpolated metadata field, and the raw node stays in the options so write-back keeps the !!js form. The standard/code/cordis presets gate tool-bash with process.platform === 'win32', verify-cordis-config allows expressions in disabled only, and the windows-shell spec pins the preset-level invariant.
Old runtimes meeting a newer session format now fail loud instead of
misreading: version refusal names the direction (newer: upgrade the
harness; older: no upgrade path) and points at the raw JSONL log, and an
event type outside the generated known vocabulary refuses resume unless
its envelope carries the new ignorable: true marker (default: required,
so a forgotten marker over-refuses instead of silently resuming a gutted
session). gen-persistence-catalog now also emits
KNOWN_SESSION_EVENT_TYPES; SQLite stores the marker in a dedicated
column (SCHEMA_VERSION 15). The versioning design (monotonic integer,
n->n+1 upgrader chain, migrate-on-continue) is recorded in the
session-log-version-mechanism Agent Note.
