provider-core 0.6.7

A cancelled Job or expired Attempt confirmed by the NMR Jobs API can settle
its original pre-execution resources and release the claim once. The SDK
exposes the checked disposition to provider loops without treating an
operator's local stop, an uncertain START or entered science as a server
revocation. Unresolved work and unacknowledged reports remain owned.

Prose interpretation now sends each outbound model HTTP request in its own
bounded Python process. The provider retains conversation, scientific
preparation and Attempt ownership. Original request deadlines, framed
responses, TLS verification, cooperative close and TERM/KILL escalation
have independently checked cleanup boundaries. An unconfirmed child exit
does not free capacity or authorize another scientific request. The process
carrier requires the Linux/POSIX environment used by provider containers;
unsupported opaque TLS customizations are explicitly refused.

ProseService carries one configured language-model service's backoff and
valid Retry-After between Jobs. A subsequent interpretation cannot bypass
that service's outstanding delay, while another configured service may remain
available. Providers should construct these service bindings once at startup
and keep prose-dependent Jobs unstarted while all alternatives are delayed;
the SDK does not own the provider's Job-discovery loop.

Result publication now reports elapsed wait for the original retained report.
One delivery_stalled warning also covers a matching NMR Jobs API receipt
followed by an uncompleted local queue update. These observations do not
cancel storage, replay an accepted report, or release an unfinished Attempt.
Protected diagnostics retain the age of the original execution failure.

The local B4 SDK and consumer fault tests use HTTPS peers, bounded outages,
counted scientific operations and exact publication receipts. They do not
qualify the native four-provider deployment. In particular, reconstructed
SECS and NMRNet branches require new installed-artifact testing, and the
previous environment blocked three Unix-domain-socket SDK tests. Complete
release artifact qualification and positive native/container deployment
checks remain release gates; see notes 061 and 060.

This version does not implement the later shared provider-service extraction
or recovery of selected results lost when a provider dies before durable
outbox handoff. No NMR Jobs API schema change is required.
