Changes

Claude Code session-budget demo

Layer / File(s)	Summary
HTTPS proxy configurations authbridge/demos/session-budget/local/config-https.yaml, authbridge/demos/session-budget/local/config-https-observe.yaml	Adds enforcement and observation configurations with TLS bridging, ordered parsers, Redis-backed session budgets, pause handling, session expiration, and fallback sessions.
Claude Code HITL demo guide authbridge/demos/session-budget/hitl-with-claude-code.md	Documents prerequisites, setup, Claude Code proxy settings, interactive approval flows, shadow mode, reset, cleanup, and caveats.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to e0969

The guide could lead users to expose a gateway bearer token through shared project configuration and could mislead them about approval, response-status, and retry behavior. The PR is not merge-ready until the credential-handling guidance and inaccurate behavior descriptions are corrected or explicitly accepted.

In `@authbridge/demos/session-budget/hitl-with-claude-code.md`:
- Around line 163-164: Update the observe-mode documentation near the
approver-terminal guidance to avoid promising an HTTP 200 response; state that
observe mode permits the request to continue but upstream authentication
failures, rate limits, or other errors may still produce non-200 responses.
- Around line 131-134: Update the “First turn over budget” description in the
session-budget documentation to state that turn 1 completes and records its
response tokens, while the next request detects the exceeded cached budget and
requests approval. Keep the existing proxy log, reason, and pause-prompt details
consistent with this corrected sequence.
- Around line 84-105: Update the demo instructions to use the project-scoped
.claude/settings.local.json for proxy and CA configuration instead of
.claude/settings.json, while keeping ANTHROPIC_AUTH_TOKEN in the process
environment or a secret store and out of shared project settings.

Adds three new files for the session-budget HITL + Claude Code local demo: a markdown walkthrough and two YAML config variants (config-https.yaml for pause mode, config-https-observe.yaml for shadow/observe mode). All CI passes, no secrets or supply-chain concerns, DCO sign-off present on all commits.

All checks pass. Ready for human review.
