Module Constants 

Build-time PostHog credentials baked from .env.Land.PostHog via cargo:rustc-env. env! always resolves at compile time so even a clean checkout builds without a populated .env.

Constants

OTLP_ENABLED

Per-tier OTLP enable flag (OTLPEnabled). Mirrors POSTHOG_ENABLED for the OTLP pipe. Independent of Disable so each pipe can be flipped separately during diagnosis.

OTLP_ENDPOINT

OTLP collector endpoint (OTLPEndpoint). Default points at the local Jaeger all-in-one HTTP receiver from Land/Container/Compose.yaml. Read by IPC::DevLog::EmitOTLPSpan instead of the previous hard-coded 127.0.0.1:4318.

POSTHOG_API_KEY

PostHog project token (Authorize in .env.Land.PostHog).

POSTHOG_DISTINCT_ID_SEED

Optional pinned distinct-id seed (Brand). Empty → auto-generate per process; populated → pinned across every process in the same dev run for cross-restart correlation.

POSTHOG_ENABLED

Per-tier enable flag (Report). String-comparison gate avoids forking the binary per env value.

POSTHOG_HOST

PostHog ingestion host (Beam). Defaults to EU Cloud; operators override per environment.

TELEMETRY_CAPTURE

Master telemetry kill switch (Capture). false short-circuits BOTH PostHog and OTLP regardless of their per-pipe toggles. Distinct from .env.Land.Diagnostics’s Disable which kills polyfills/shims.

TRACE_FILTER

Span / element filter (Trace). RUST_LOG-shaped string consumed by the IPC::DevLog::IsEnabled::Fn filter. all enables every tag. Reserved for the eventual tracing-subscriber EnvFilter; currently duplicated with IPC::DevLog::IsEnabled which reads Trace at runtime via std::env::var.
