All information you need is provided in <observed_from_primary_session> messages. Create observations from what you observe - no investigation needed.\n\nYour job is to monitor a different Claude Code session happening RIGHT NOW, with the goal of creating observations and progress summaries as the work is being done LIVE by the user. You are NOT the one doing the work - you are ONLY observing and recording what is being built, fixed, deployed, or configured in the other session.\n\nSPATIAL AWARENESS: Tool executions include the working directory (tool_cwd) to help you understand:\n- Which repository/project is being worked on\n- Where files are located relative to the project root\n- How to match requested paths to actual execution paths\n\nWHAT TO RECORD\n--------------\nFocus on durable technical signal:\n- What the system NOW DOES differently (new capabilities)\n- What shipped to users/production (features, fixes, configs, docs)\n- Changes in technical domains (auth, data, UI, infra, DevOps, docs)\n- Concrete debugging or investigative findings from logs, traces, queue state, database rows, and code-path inspection\n\nUse verbs like: implemented, fixed, deployed, configured, migrated, optimized, added, refactored, discovered, confirmed, traced\n\n✅ GOOD EXAMPLES (describes what was built or learned):\n- \"Authentication now supports OAuth2 with PKCE flow\"\n- \"Deployment pipeline runs canary releases with auto-rollback\"\n- \"Database indexes optimized for common query patterns\"\n- \"Observation queue for claude-mem session timed out waiting for an agent pool slot\"\n- \"Fallback processing abandoned pending messages after Gemini and OpenRouter returned 404\"\n\n❌ BAD EXAMPLES (describes observation process - DO NOT DO THIS):\n- \"Analyzed authentication implementation and stored findings\"\n- \"Tracked deployment steps and logged outcomes\"\n- \"Monitored database performance and recorded metrics\"\n\nWHEN TO SKIP\n------------\nSkip routine operations:\n- Empty status checks\n- Package installations with no errors\n- Simple file listings with no follow-on finding\n- Repetitive operations you've already documented\n- File related research that comes back empty or not found\n\nIf skipping, return an empty response only. Do not explain the skip in prose.\n\nIMPORTANT: Continue generating observations from tool use messages using the XML structure below.\n\nOUTPUT FORMAT\n-------------\nOutput observations using this XML structure:\n\n<observation>\n  <type>[ bugfix | feature | refactor | change | discovery | decision | security_alert | security_note ]</type>\n  \n  <title>[title: Short title capturing the core action or topic]</title>\n  <subtitle>[subtitle: One sentence explanation (max 24 words)]</subtitle>\n  <facts>\n    <fact>[Concise, self-contained statement]</fact>\n    <fact>[Concise, self-contained statement]</fact>\n    <fact>[Concise, self-contained statement]</fact>\n  </facts>\n  <!--\n    facts: Concise, self-contained statements\nEach fact is ONE piece of information\n      No pronouns - each fact must stand alone\n      Include specific details: filenames, functions, values\n\nfiles: All files touched (\n…(truncated, 1807 more chars)\n\nTurn 2 — User\n\n--- MODE SWITCH: PROGRESS SUMMARY ---\n⚠️ CRITICAL TAG REQUIREMENT — READ CAREFULLY:\n• You MUST wrap your ENTIRE response in <summary>...</summary> tags.\n• Do NOT use <observation> tags. <observation> output will be DISCARDED and cause a system error.\n• The ONLY accepted root tag is <summary>. Any other root tag is a protocol violation.\n\nPROGRESS SUMMARY CHECKPOINT\n===========================\nWrite progress notes of what was done, what was learned, and what's next. This is a checkpoint to capture progress so far. The session is ongoing - you may receive more requests and tool executions after this summary. Write \"next_steps\" as the current trajectory of work (what's actively being worked on or coming up next), not as post-session future work. Always write at least a minimal summary explaining current progress, even if work is still in early stages, so that users see a summary output tied to each request.\n\nClaude's Full Response to User:\nQuestion 3 of N\n\nThe plan's Step 2 says to rename the stale funnelId acceptance describe block — but only mentions tiEnvProvider.test.ts. The actual idpAuthenticator.test.ts has the same stale pattern at line 273:\n\n// idpAuthenticator.test.ts line 273 — NOT in the plan's Step 2\ndescribe('funnelId acceptance', () => {\n  it('passes funnelId as traceId down to the logger if funnelId is passed', async () => {\n\nMy recommendation: rename it to traceId acceptance / passes traceId down when provided for the same consistency reason — both tests were introduced together for FHIR-2102 and should be updated together. It's a two-line change that keeps the test suite coherent with the source code rename.\n\nShould we add the idpAuthenticator.test.ts funnelId acceptance rename to Step 2's scope? (Recommended: yes)\n\nRespond in this XML format:\n<summary>\n  <request>[Short title capturing the user's request AND the substance of what was discussed/done]</request>\n  <investigated>[What has been explored so far?

This is a checkpoint to capture progress so far. The session is ongoing - you may receive more requests and tool executions after this summary.

Always write at least a minimal summary explaining current progress, even if work is still in early stages, so that users see a summary output tied to each request.\n\nClaude's Full Response to User:\nQuestion 4 of N\n\nThere's a convention mismatch between the implementation plan and your instructions:\n\n- Plan says: fix(FHIR-2120): propagate traceId to TiEnvProvider.getEnv across specialist service\n- Your instructions say: PR title prefix chore(fhir-2120): \n\nSemantically, this change is a fix — the traceId was available but not forwarded, causing every TiEnvProvider log line to emit 'unknown' instead of the real trace context. That's a defect in log correlation, which matches fix. chore typically means maintenance work with no behavior change.\n\nMy recommendation: use fix(FHIR-2120) — it accurately describes what we're doing and will make the PR easier to understand during code review and release note generation.\n\nDo you want to override the plan's fix prefix with chore as specified in your instructions, or keep fix? (Recommended: keep fix)\n\nRespond in this XML format:\n<summary>\n  <request>[Short title capturing the user's request AND the substance of what was discussed/done]</request>\n  <investigated>[What has been explored so far?

Always write at least a minimal summary explaining current progress, even if work is still in early stages, so that users see a summary output tied to each request.\n\nClaude's Full Response to User:\nQuestion 5 of N\n\nThe plan explicitly removes the FHIR-2102 comment block from tiEnvProvider.ts (lines 38–39 and 83–84) because \"the param is no longer temporary in name.\" However, idpAuthenticator.ts has the same comment pattern on two methods (lines 24–25 and 60–61):\n\n// https://doctolib.atlassian.net/browse/FHIR-2102\n// Temporarily accepts traceId before loggers are refactored\nstatic async authenticateWithTiIdp(...)\n\nThese are subtly different from the tiEnvProvider comment. The tiEnvProvider comment justified a parameter rename (funnelId was the \"temporary\" name). The idpAuthenticator comments justify a logging architecture that is still not resolved — FHIR-2102 (the full logger refactor) is a separate open ticket.\n\nMy recommendation: leave the FHIR-2102 comments in idpAuthenticator.ts untouched — they track future work in a separate issue, they're still accurate, and removing them without completing FHIR-2102 loses the tracking context. Only the tiEnvProvider comment gets removed (as the plan says) because that one was specifically about the parameter name being temporary.\n\nDo you agree the idpAuthenticator.ts FHIR-2102 comments should be left as-is? (Recommended: yes — they belong to a separate ticket)\n\nRespond in this XML format:\n<summary>\n  <request>[Short title capturing the user's request AND the substance of what was discussed/done]</request>\n  <investigated>[What has been explored so far?

Always write at least a minimal summary explaining current progress, even if work is still in early stages, so that users see a summary output tied to each request.\n\nClaude's Full Response to User:\nQuestion 6 of N\n\nYour instructions require a TDD approach, but the plan's order is implementation-first (Steps 1–9 source changes, then Step 10 test updates). For parameter-threading changes, TDD means: write a failing assertion that traceId was forwarded → run test → watch it fail → add the parameter → watch it pass.\n\nThe practical bottom-up TDD ordering for this ticket would be:\n\n1. tiEnvProvider: rename describe/it blocks (no red/green needed — cosmetic)\n2. IdpChallengeService: write failing test (tiEnvProviderSpy called with traceId),\n   then add traceId? to getTiEnvValues/getIdpClient/getDiscoveryDocument/fetchChallengeWithConsent\n3. ChallengeValidator: write failing test (fetchChallengeWithConsent called with traceId),\n   then add traceId? to validateAndGetChallenge + fetchNewChallengeAndCache\n4. idpAuthenticator: write failing assertion (validateAndGetChallenge called with traceId),\n   then forward at the 4 call sites\n5. VauClient: write failing test (tiEnvProviderSpy called with traceId),\n   then add traceId? to fetchEncryptionCertificate/post\n6. VauService: write failing assertion (VauClient spies called with traceId),\n   then add traceId? to fetchValidEncryptionKey/prepareAndExecutePostRequest\n7. gematikERezeptService + listeners: write failing assertions, then forward at call sites\n\nEach unit only propagates one level at a time, keeping the red→green cycles tight.\n\nMy recommendation: follow this bottom-up TDD ordering instead of the plan's implementation-first ordering. It also naturally ensures each layer compiles and tests pass before moving to the next.\n\nDo you agree to use this bottom-up TDD ordering during implementation? (Recommended: yes)\n\nRespond in this XML format:\n<summary>\n  <request>[Short title capturing the user's request AND the substance of what was discussed/done]</request>\n  <investigated>[What has been explored so far?

This could be cleaned up with an options object, but that would be a larger refactor touching every call site and every other method in the chain — well beyond FHIR-2120's scope.\n\nThe alternative — inserting traceId? between service and smcbIccsn, or between two required params — would break every existing call site and is not backward-compatible.\n\nMy recommendation: keep traceId? as the last positional parameter — it's consistent with the pattern used in every other method in this chain (IdpChallengeService, VauService, VauClient), and the options-object refactor belongs to FHIR-2102 (the full logger refactor), not here.\n\nDo you agree traceId? should be the last positional parameter throughout the chain?
