Inline comments:
In `@en/docs/ai-gateway/next/analytics/index.md`:
- Line 30: Update the OpenTelemetry analytics table entry to expand OTLP as
“OpenTelemetry Protocol (OTLP)” and LLM as “large language model (LLM)” at their
first uses, while preserving the existing description and link.

In `@en/docs/ai-gateway/next/analytics/opentelemetry-analytics.md`:
- Line 20: Update the top of the OpenTelemetry Analytics document by adding a
blank line after the raw block marker and changing the top-level heading text to
sentence case: “OpenTelemetry analytics”.
- Around line 135-138: Add a concise introductory sentence immediately before
each analytics documentation table, including the [analytics], endpoint, timeout
and retry, and troubleshooting tables. Each sentence should explain what the
following table helps configure or diagnose, while preserving the existing table
content and headings.
- Around line 73-75: Remove request_headers and response_headers from the
minimal [collector] quick-start configuration, unless the example also includes
the required Analytics Header Filter configuration to protect sensitive values
before capture.
- Line 177: Update the retry_abort_queue_ratio documentation and its related
explanation to match the worker’s boundary behavior: clarify that a value of 1
aborts when the queue is full, or explicitly document a strict greater-than
comparison if that is the intended implementation. Keep the threshold semantics
consistent in both referenced descriptions.
- Line 24: Update the documentation to spell out each abbreviation at its first
occurrence—OTLP, SaaS, ALS, CA, TLS, mTLS, LLM, and MCP—then retain the
abbreviations for subsequent uses, including the referenced sections.
- Around line 24-26: Revise the prose sentences and table-cell text identified
in the OpenTelemetry analytics documentation, including the paragraph around the
OTLP log-record description, so every sentence contains fewer than 26 words.
Split long sentences or move explanatory details from table cells into
surrounding paragraphs without changing the technical meaning.
- Around line 179-181: Update the retry-behavior description near the 5xx/429
guidance to state that other 4xx responses are not retried, and describe
authentication, payload-size, and payload-shape errors as possible causes
instead of attributing all such responses to payload shape.
- Line 3: Shorten the frontmatter description to fewer than 158 characters and
expand or define OTLP and LLM at their first use, while preserving the
description’s focus on AI Gateway analytics, OpenTelemetry export, token usage,
and cost.

In `@en/docs/api-gateway/next/analytics/opentelemetry-analytics.md`:
- Line 2: Update the page title and H1 to use sentence case: “Configure
OpenTelemetry analytics” and “OpenTelemetry analytics.” Add a blank line after
the {% raw %} template tag and ensure the Markdown headings have surrounding
blank lines.
- Around line 22-24: In the OpenTelemetry analytics documentation, split the
identified sentences exceeding 25 words into shorter sentences of fewer than 26
words. Put the key information first while preserving the existing technical
meaning and all details about OTLP log records, transport, and supported
observability destinations.
- Around line 133-136: Update the documentation around each affected
configuration table to add a brief, meaningful introductory sentence immediately
before it, explaining what the table helps configure or troubleshoot. Apply this
consistently to all referenced tables while preserving their existing content
and structure.
- Around line 23-24: Update the analytics documentation to replace figurative
wording with direct terms: use “are exported to” for observability destinations,
“controls activation” for the switch behavior, and “synchronized request burst”
for the request pattern. Apply these wording changes at the referenced
occurrences while preserving the surrounding meaning.
- Around line 177-179: Update the retry behavior description to call non-429 4xx
responses “non-retryable client error” rather than attributing all of them to
payload shape; retain payload shape as one example. Apply the same wording
consistently in the retry-status list that includes 401, 403, and 413.
- Line 449: Update the templating-failure table entry to show complete
interpolation syntax: use `{{ env "VAR_NAME" }}` and `{{ file "/path/to/secret"
}}`, or link to the full credential-handling examples instead of displaying
incomplete tokens.
- Line 123: Update the ignore_path_prefixes setting description in the collector
analytics documentation to state that matching paths suppress both analytics
events and Traffic Logging lines, while preserving the existing path-prefix
behavior and example.
- Line 3: Update the frontmatter description to expand OTLP as “OpenTelemetry
Protocol (OTLP)” at first use, then define each non-exempt acronym at its first
occurrence in the document, including ALS, SaaS, TLS, mTLS, CA, PEM, LLM, MCP,
and OTel; leave standard exceptions such as API, HTTP, and JSON unchanged.
- Line 150: Remove the OTLP publisher configuration examples and table entries,
including the service_name entry, from the analytics documentation until gateway
OTLP publisher support and schema are available; leave existing supported
publisher documentation unchanged.

Do not enable raw header capture without an Analytics Header Filter.

This Helm example sets request_headers and response_headers to true without adding a per-API Analytics Header Filter policy. Because traffic_logging.masked_headers does not apply to analytics, the copied configuration can export credential-bearing headers. Remove these flags or add a filter with rules that exclude sensitive headers. Apply the same correction to the API Gateway example.

- Line 65: Update the three-item lists in the documentation near “Construction
fails closed; delivery fails open” and the corresponding sections near the other
referenced list entries to add Oxford commas before the final conjunction,
without changing the wording or meaning.
- Around line 320-321: Update the first occurrence of “GenAI” in the
OpenTelemetry semantic conventions description to “generative artificial
intelligence (GenAI)”, then retain “GenAI” for subsequent references.
- Line 159: Clarify the service_name behavior in the analytics configuration
tables on both gateway pages: specify whether omission applies the
"gateway-runtime" default, fails startup, or only guarantees service.name in
emitted OTLP resources, then align the Default and Description entries with that
behavior.

In `@en/docs/api-gateway/next/analytics/opentelemetry-analytics.md`:
- Line 318: Update the sentence beginning “AI traffic is mapped” to expand GenAI
as “generative artificial intelligence (GenAI)” at its first use, while
preserving the existing OpenTelemetry semantic-conventions wording.
- Around line 24-25: Rewrite the changed documentation sentences identified by
the affected sections to use active voice, making the actor the grammatical
subject instead of relying on passive constructions such as “are exported,” “is
emitted,” “are retried,” “are stripped,” “are carried,” and “are rendered.”
Preserve the original meaning and technical details.
