docs(extraction): state Helm OCR v2 as the 26.08.1 default (NVBug 6620878)

[kheiss-uwzoo]

Summary

• Makes the 26.08.1 release notes Helm clause match the chart: For Helm NIM deployments, Nemotron OCR v2 is the default.
• Adds the default OCR image nvcr.io/nim/nvidia/nemotron-ocr-v2:2.0.1 to the mirroring and allowlisting list. Exact repository and tag remain owned by the support matrix and nemo_retriever/helm/values.yaml.
• Related: NVBug 6628502 / PR docs(extraction): correct 26.08 release notes OCR default and POR delta (NVBug 6628502) #2548 already replaced the RC4 OCR v1 sentence. This PR keeps that generation claim explicit for Helm and restores the OCR pin in the artifact list. Inverse historical mismatch: NVBug 6198662 (26.05 chart v1 vs docs v2).

Test plan

• Search the Release Notes page for For Helm NIM deployments, Nemotron OCR v2 is the default.
• Confirm the mirroring list includes nvcr.io/nim/nvidia/nemotron-ocr-v2:2.0.1.
• Confirm Default Helm NIMs still lists that same image as enabled by default.
• Confirm nimOperator.ocr in nemo_retriever/helm/values.yaml is enabled: true with repository nvcr.io/nim/nvidia/nemotron-ocr-v2 and tag 2.0.1.

pre-draft: leakage, mkdocs --strict, ::a, ::p, ::r on the diff vs main

Base: upstream/main
Files: docs/docs/extraction/releasenotes.md

Check	Result
Leakage (page roles + see [ CTAs)	PASS — no see [ CTAs on releasenotes.md; faq/overview/multimodal-extraction were not in this diff
Allowed paths	PASS — 1 documentation file
mkdocs --strict	PASS for this diff — no new warnings from releasenotes.md; exit 1 on untracked leftover pages custom-metadata.md and user-defined-stages.md that are not in this diff
::a audit	PASS — Helm OCR default nemotron-ocr-v2:2.0.1 matches values.yaml (nimOperator.ocr.enabled: true) and the support matrix; packaged DORI runtime missing, used canonical validate_code_blocks / verify_docs / detect_drift (pass, fresh)
::p polish	Applied — Helm generation clause is explicit; exact image pin lives in the mirroring list and support matrix
::r style	95% — no blocking issues on the changed bullets

Code drift (not in this docs PR): No runtime mismatch. A release-note vs chart default-generation contract check is still missing; that belongs in a separate eng/test PR, not this docs PR.

PR: this draft

Fixes NVBug 6620878.

Greptile Summary

Updates the 26.08.1 release notes to explicitly identify Nemotron OCR v2 as the Helm NIM default.

• Adds nvcr.io/nim/nvidia/nemotron-ocr-v2:2.0.1 to the mirroring and allowlisting artifact list.
• Directs readers to the support matrix and Helm configuration documentation for the chart image details.

Confidence Score: 5/5

The PR appears safe to merge with no actionable issues identified.

The documented Helm OCR default and exact image are consistent with the chart configuration and support matrix, and both referenced documentation anchors resolve.

Important Files Changed

Filename	Overview
docs/docs/extraction/releasenotes.md	The revised Helm OCR default, image pin, and documentation links agree with the checked-in chart values, support matrix, and Helm README.
