- metrics_reference: remove phantom tier label (tier lives in the JSONL routing log), seed 404 among canonical outcome codes, document the previously undocumented run/decision/call counters, stage-router, and advisor-gate metric families, update the cardinality table - getting_started: mark X-Switchyard-Version and the telemetry opt-out as not yet implemented, cross-reference known_issues - DEVELOPMENT: --extra server -> cli, replace missing secrets/ template with the actual env-var mechanism - examples/libsy.py: replace non-existent Step.Decision / call.decision with the real binding API - release_workflow: fix crate publish order per publish.yml - toml_schema: add the advisor route section (13 knobs) and correct the duplicate (client, id) behavior to a warning - escalation_router_routing: drop cost from the snapshot description and reword judge attribution to the JSONL-log behavior - core_concepts: add noop and advisor rows to the algorithm table - known_issues: mark the x-switchyard-session-id item as fixed
WalkthroughThe pull request updates development, routing, telemetry, metrics, release, and schema documentation. It also updates the example client to derive models from requests and process completed stream outcomes. ChangesProject documentation and example behavior
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The documentation update still contains conflicting metric vocabulary and omits a documented routing-log tier, which could lead operators to query or interpret telemetry incorrectly. This is a bounded documentation-only issue, so the PR is mergeable with explicit owner follow-up. Poem

reference to include classifier alongside strong and weak, preserving the
clarification that tier is a routing-log field rather than a Prometheus label.
- Around line 38-39: Update the switchyard_runs_total documentation so its
outcome values exactly match the emitted run-specific vocabulary: success,
retryable_error, and other_error. Keep the switchyard_run_duration_ms
description unchanged and ensure the table agrees with the later outcome
guidance.

Align the outcome values for switchyard_runs_total.
Line 38 documents outcome as ok or error. Later, Lines 126-130 and Line 201 state that outcome has exactly success, retryable_error, and other_error. Clarify the run-specific label vocabulary or update this table to match the emitted values. Otherwise, the cardinality and query guidance is ambiguous.

Document classifier as a routing-log tier.
This paragraph limits the routing-log tier values to strong and weak. docs/routing_algorithms/escalation_router_routing.md documents successful judge calls with tier=classifier at Lines 158-161. Add classifier to the routing-log description, or scope the current statement to target calls. Otherwise, operators can omit judge overhead from log queries.
