An availability target's configured poll interval only seeded the
adaptive scheduler: BuildPlan derived every instance's cadence from the
global adaptive bounds, and a failing probe raised the staleness score
and error penalty, collapsing the probe interval toward the global
5-second minimum. With interval 120s and failure threshold 4 the alert
was promised after ~8 minutes of downtime but fired within the first
minute because the four consecutive failures accumulated at the
collapsed cadence (#1582).
Availability checks promise pollInterval x failureThreshold as the
detection window, so the cadence is a user contract, not a scheduling
hint. Add a FixedIntervalPollProvider extension that pins an instance
to its configured interval, implement it for availability targets, and
bypass adaptive selection wherever the next run is computed (plan
building, rescheduling, and the non-adaptive fallback paths).
The Windows installer compared the downloaded agent's --version output
(v6.0.5) against the server's /api/version value (6.0.5) literally, so
every matching install still warned about a version mismatch (#1527).
Strip the leading v from both sides before comparing, matching what
install.sh already does.
New table-driven tests raise branch coverage on
SplitTrailingProviderToolNamePrefix and the JSON and plain function
tool-call leak-index helpers, covering empty content, no-alnum tails,
prefix-hold versus pass-through and regex no-match paths. Test-only.
New table-driven tests raise branch coverage on ContextWindowTokens,
extractModelName, isDigits, rateLimitInfo, normalizeOpenAICompatibleChatURL,
stop-reason normalization and the OpenAI, Anthropic and Gemini tool-choice
converters, covering date-suffix stripping, malformed URLs and default arms.
Test-only, no source changes.
New table-driven tests raise branch coverage on the timeout, curl/wget,
env and recovery-point canonicalization helpers in internal/ai/tools,
exercising previously uncovered flag-parsing arms, mutation-method
detection and numeric-detail type cases. Test-only, no source changes.
