Route all Rocket internal logs through gem_tracing

[Copilot]

Rocket's internal log events (guard failures, 404s, catcher responses) were emitted via its own RocketLogger with a > prefix format, inconsistent with the project's gem_tracing structured output.

Root cause

Rocket 0.5 uses the log crate and registers RocketLogger via log::set_boxed_logger — a one-time global. Nothing previously claimed that slot first.

Changes

• crates/tracing — add log = "0.4" dep; implement GemLogger (log::Log) that converts every log event into a tracing event routed through the existing FmtSubscriber; expose init() which registers GemLogger and sets the level filter from ROCKET_LOG_LEVEL env var (default: normal; values: off / critical / normal / debug)

• apps/api/src/main.rs — call gem_tracing::init() at the top of main(), before any rocket::build(). Rocket's subsequent set_boxed_logger call silently fails (already taken), so its events flow through GemLogger

• apps/api/src/devices/guard.rs — explicitly log auth guard failures via info_with_fields! with structured fields (uri, status, error, user_agent) before the guard returns an error outcome

Result

Rocket's "Request guard \AuthenticatedDevice` failed: ..."and similar messages now emit in the same format as all other application logs. Log verbosity is runtime-configurable viaROCKET_LOG_LEVEL`.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• api.rocket.rs
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node /home/REDACTED/work/_temp/ghcca-node/node/bin/node --enable-source-maps /home/REDACTED/work/_temp/copilot-developer-action-main/dist/index.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
