The previous test asserted that OpenAI-responses sessions would NOT get
synthetic tool results for orphaned tool calls. With repairToolUseResultPairing
now running universally, the correct behavior is that orphaned tool calls
get a synthetic tool_result — matching what OpenAI actually requires.

repairToolUseResultPairing was gated behind !isOpenAi, skipping orphaned
tool_result cleanup for OpenAI providers. When limitHistoryTurns truncated
conversation history, tool_result messages whose matching tool_call was
before the truncation point survived and were sent as function_call_output
items with stale call_id references. OpenAI rejects these with:
"No tool call found for function call output with call_id ..."
Enable the repair universally — all providers need it after truncation.

* fix: treat HTTP 502/503/504 as failover-eligible (timeout reason)
When a model API returns 502 Bad Gateway, 503 Service Unavailable, or
504 Gateway Timeout, the error object carries the status code directly.
resolveFailoverReasonFromError() only checked 402/429/401/403/408/400,
so 5xx server errors fell through to message-based classification which
requires the status code to appear at the start of the error message.
Many API SDKs (Google, Anthropic) set err.status = 503 without prefixing
the message with '503', so the message classifier never matched and
failover never triggered — the run retried the same broken model.
Add 502/503/504 to the status-code branch, returning 'timeout' (matching
the existing behavior of isTransientHttpError in the message classifier).
Fixes#20999
* Changelog: add failover 502/503/504 note with credits
* Failover: classify HTTP 504 as transient in message parser
* Changelog: credit taw0002 and vincentkoc for failover fix

* fix(security): redact sensitive data in OTEL log exports (CWE-532)
The diagnostics-otel plugin exports ALL application logs to external
OTLP collectors without filtering. This leaks API keys, tokens, and
other sensitive data to third-party observability platforms.
Changes:
- Export redactSensitiveText from plugin-sdk for extension use
- Apply redaction to log messages before OTEL export
- Apply redaction to string attribute values
- Add tests for API key and token redaction
The existing redactSensitiveText function handles common patterns:
- API keys (sk-*, ghp_*, gsk_*, AIza*, etc.)
- Bearer tokens
- PEM private keys
- ENV-style assignments (KEY=value)
- JSON credential fields
Fixes#12542
* fix: also redact error/reason in trace spans
Address Greptile feedback:
- Redact evt.error in webhook.error span attributes and status
- Redact evt.reason in message.processed span attributes
- Redact evt.error in message.processed span status
* fix: handle undefined evt.error in type guard
* fix: redact session.state reason in OTEL metrics
Addresses Greptile feedback - session.state reason field now goes
through redactSensitiveText() like message.processed reason.
* test(diagnostics-otel): update service context for stateDir API change
* OTEL diagnostics: redact sensitive values before export
* OTEL diagnostics tests: cover message, attribute, and session reason redaction
* Changelog: note OTEL sensitive-data redaction fix
* Changelog: move OTEL redaction entry to current unreleased
