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.
Introduce @deepseek-ai/dsh-sdk-app as the thin application layer for the built-in sdk profile. The bundle contributes the JSON-RPC server and startup-only profile metadata, while dsh-base continues to own the shared agent, provider, persistence, and tool composition.
Publish ctx.appReady from the launcher only after the Loader tree and launcher-owned setup succeed. The stdio lifetime binding leaves stdin unread until the protocol transport claims it and defers EOF exit 0 until readiness commits, so early protocol frames remain buffered and a racing startup failure remains the nonzero process outcome. Fiber disposal cancels both pending lifecycle listeners.
Register the bundle in the CLI resolver closure, generated configuration catalog, workspace graph, and built-bin smoke. Startup tests prove that base plus sdk-app exposes the SDK server without taking ownership of shared runtime plugins; focused and built-bin regressions cover early input, EOF readiness, and startup-error precedence.
AttachmentStore.saveImage now resolves SavedImageAttachment: the durable
reference paired with the submitted raster's intrinsic facts, so a store may
persist a canonical re-encoding while callers keep the source dimensions for
coordinate mapping. saveImages keeps returning refs; every fake store and the
cordis API catalog follow the new signature.
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 seam answered one question — what is behind this environment-variable
name — and that shape cannot hold what an authorization grant is: a
multi-field, rotating value keyed by a provider id rather than by a POSIX
identifier. The Models page already works around the gap by inventing a
synthetic environment name (`MINIMAX_CN_API_KEY`) for a route the user added
by hand, because the store's key must look like one.
`CredentialKey` is `<scope>/<id>`, where the scope is the owning plugin's
registered name. The owner is in the key because a `grant` payload is written
in its owner's format: two plugins serving the same provider name would
otherwise read each other's payload, and a record left by an uninstalled
plugin could not be told from a live one. The `/` also keeps the grammar
disjoint from `CredentialRef`, so the key spaces cannot collide.
`CredentialRecord` is `api-key` (key and/or provider environment values) or
`grant` (an opaque, owner-owned payload). The asymmetry is deliberate: an api
key is the harness's own data, a grant is a package it carries for someone
else. `modifyRecord` is the only write path because a correct write depends
on the current value — a token refresh is read-decide-replace under one
cross-process lock, without which two processes rotating one refresh token
lose whichever wrote first.
`.credentials.yaml` becomes a versioned two-section document. The pre-release
flat layout is refused by name, with the entry count and the one edit needed,
rather than read as an empty store — which would surface as an authentication
failure on the first request instead of at load. A grant payload is admitted
in both directions, so a value the document could not read back exactly as
written is refused rather than stored lossily.
