LitestarOpenTelemetryInstrumentationMiddleware.handle constructed a fresh OpenTelemetryMiddleware on every request. Cache it per next_app so tracers and metric instruments are allocated once.

…e-cache fix: cache OpenTelemetryMiddleware in litestar instrumentation

…test code, handler leak) - helpers/path.py: allow dots in VALID_PATH_PATTERN (e.g. /api.v1/metrics) - bootstrappers/base.py: standardize "is not ready: {reason}" format - bootstrappers/fastapi_bootstrapper.py: fix "is differ" -> "differs" - tests/instruments/test_sentry_instrument.py: remove unused LoggingIntegration() expression and import - instruments/logging_instrument.py: track handlers created by MemoryLoggerFactory and close them (plus restore propagate=True) on LoggingInstrument.teardown

Use a dataclasses.field with default_factory=lambda: None so the slot is properly initialized on subclasses (FastAPILoggingInstrument etc.). With a plain default=None the inherited init=False field is silently skipped in the subclass-generated __init__ when parent has slots=True.

Fix/low severity cleanups

Add lite_bootstrap.exceptions module with LiteBootstrapError(RuntimeError) base and BootstrapperNotReadyError, ConfigurationError, TeardownError subclasses. TeardownError aggregates every (instrument_name, exception) pair into both the message string and a public .errors attribute, so detail survives even when LoggingInstrument tears down before later instrument failures are logged. All four prior RuntimeError raise sites in the package migrate to the new tree; subclassing RuntimeError keeps existing `except RuntimeError:` callers working.

tracer_injection runs once per log line. The previous in-function `try / from opentelemetry import trace / except ImportError` paid the try-machinery and import-lookup cost on every call, even though import_checker.is_opentelemetry_installed already settles the question at startup. Move the import into a module-level guard parallel to the existing is_structlog_installed block, defining a no-op fallback tracer_injection in the else branch for environments without OTel.

fix: preserve teardown error detail via TeardownError exception

…-import perf: hoist OTel import in tracer_injection to module level

…nfig Replace two getattr(..., None) calls in PyroscopeInstrument.bootstrap() with direct attribute access. The fields are added to PyroscopeConfig with default None; in framework configs MRO causes OpentelemetryConfig's declarations to win, so behavior is unchanged. Standalone PyroscopeConfig users can now set these fields directly without the cross-class coupling. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

refactor: declare opentelemetry_service_name/namespace on PyroscopeCo…

LoggingInstrument.is_ready() previously returned False whenever service_debug=True — and BaseConfig.service_debug defaults to True. So out of the box, the structured-logging instrument silently skipped its own bootstrap, and users assumed the JSON logging pipeline was working when it wasn't. Add a dedicated logging_enabled: bool = True field on LoggingConfig and gate is_ready() on it instead. service_debug stays focused on framework debug mode (FastAPI/Litestar app.debug). Default behavior changes: projects with no overrides now get structured logging. Users who want the old skip-logging behavior set logging_enabled=False explicitly.

feat: add logging_enabled flag, decouple from service_debug

Both bootstrap skip paths (missing dependency, not ready) now emit warnings.warn with distinct UserWarning subclasses (InstrumentDependencyMissingWarning, InstrumentNotReadyWarning, sharing InstrumentSkippedWarning base) so users can filter, capture, or escalate each independently. Previously not-ready skips went to logger.info and were silently dropped before the logging instrument finished bootstrapping. Also drop stale service_debug=False notes from the docs (logging is now gated by logging_enabled, default True). Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

feat: unify instrument skip feedback through warning subclasses
