* feat(pat): A-core minimum viable loop for host-owned PAT
Enables third-party agents to integrate PAT via the smallest possible
contract surface. The flow a host needs to ship end-to-end:
1. Export DINGTALK_DWS_AGENTCODE in the spawned shell.
2. Run any `dws ...` business command.
3. On PAT hit, CLI exits with code 4 and writes a single-line stderr
JSON following docs/pat/contract.md §2.
4. Host parses the JSON and invokes `dws pat chmod <scope>...
--agentCode ... --grant-type ...` to grant.
5. Host replays the original command.
This PR intentionally ships ONLY the chmod path plus the host-owned
switch; the async flow (apply / status / scopes + authRequestId
registry + PAT_SCOPE_AUTH_REQUIRED active-request branch) lands in a
follow-up stacked PR (A-ext).
Scope of A-core:
- Host-owned PAT trigger: auth.HostOwnsPATFlow() keyed exclusively on
DINGTALK_DWS_AGENTCODE (DINGTALK_AGENT / DWS_CHANNEL / claw-type do
NOT participate).
- claw-type: hard-wired to "openClaw" in pkg/edition/default.go
MergeHeaders hook, matching historical main behavior and decoupled
from DINGTALK_AGENT.
- dws pat chmod: factory-built (newChmodCommand) so the PAT subcommand
tree has no shared package-level caller.
- stderr JSON classifier: internal/errors/pat.go covers PAT_NO_PERMISSION
/ PAT_LOW_RISK / PAT_MEDIUM_RISK / PAT_HIGH_RISK / PAT_SCOPE_*
selectors and fills data.hostControl for host consumption.
- Env contract: DINGTALK_SESSION_ID / DINGTALK_TRACE_ID /
DINGTALK_MESSAGE_ID carry HTTP trace headers (Chain B);
DWS_SESSION_ID (+ REWIND_SESSION_ID alias) is the lone fallback for
`dws pat chmod --session-id` (Chain A). The two chains are
independent; aliases do not cross-pollinate.
- Docs: docs/pat/{README,contract,host-integration}.md + refreshed
docs/architecture.md "PAT Architecture" chapter + docs/reference.md
PAT section. error-catalog.md folded into contract.md §6.
- Tests: host-owned signal, stderr contract, classifier, chmod factory,
retry / poll loop for the CLI-owned chmod path.
Compatibility: no breaking changes on main. All non-PAT commands are
untouched.
Follow-up PRs (in order):
- codex/pat-ext : dws pat apply / status / scopes + AsyncRegistry.
- codex/pat-oss-refactor (aka PR B) : oauth_helpers / secure_store
refactors split out per code review.

Address two reviewer findings on top of the PAT-core series.
Fix:
- chmod: resolveSessionIDFromEnv silently selects DWS_SESSION_ID; drop
the slog.Warn that emitted both raw session ids into stderr /
~/.dws/logs.
- Remove every docs/pat/contract.md / error-catalog.md /
host-integration.md anchor from comments, help, and tests; those
files were never added by this branch. Comments are now self-contained
or point to docs/reference.md where applicable.
Refactor:
- internal/errors/pat.go: extract lookupCodeIn so getPATErrorCode and
getDWSGatewayErrorCode share one traversal; have ClassifyPatAuthCheck
delegate to getPATErrorCode instead of repeating the enum walk.
- internal/errors/pat.go + internal/app/pat_auth_retry.go: extract
ApplyHostMutations as the single injection point for data.hostControl
+ data.openBrowser; cleanPATJSON and enrichPATErrorForHostControl now
share it so the two stderr-JSON write paths cannot drift.
- internal/app/pat_auth_retry.go: drop buildPATScopeHostJSON and
buildHostControlState dead 1-line wrappers.
- internal/pat/chmod.go: drop unused patApply/Status/Scopes constants;
derive legacyToolArgs from toolArgs by clone + scopes->scope rename so
the two payloads stay in lock-step on every other field.
