+# Doc Object Pipeline
+
+Commit-bound documentation summaries generated at merge time and stored via `git notes`.
+
+## Overview
+
+When a PR merges to `main`, the `ai_claude-rollback-safety` workflow generates a structured
+"doc object" — YAML frontmatter plus markdown prose — summarizing the change in documentation
+terms. The object is attached to the squash commit SHA in a separate git ref that does not
+appear in normal `git log` output:
+
+    git notes --ref=refs/notes/doc-objects add -F doc-object.md <sha>
+
+The pre-merge Claude job generates the doc object and stores it as a collapsible PR comment.
+The post-merge `doc-object-attach` job reads that comment, substitutes the real merge SHA,
+and pushes the note.
+
+## Fetching doc objects locally
+
+    git fetch origin refs/notes/doc-objects:refs/notes/doc-objects
+    git notes --ref=refs/notes/doc-objects show <sha>
+
+To walk all doc objects across a commit range (e.g. for release-notes input):
+
+    git rev-list v25.04..v25.05 | while read sha; do
+      git notes --ref=refs/notes/doc-objects show "$sha" 2>/dev/null && echo "---"
+    done
+
+## Schema
+
+Each doc object has two parts:
+
+**YAML frontmatter** — machine-readable fields used for filtering and routing:
+
+| Field | Required | Description |
+|---|---|---|
+| `commit` | yes | 7-char short SHA |
+| `title` | yes | Conventional-commit-style title |
+| `type` | yes | `feature \| bugfix \| refactor \| docs \| chore \| security \| ci \| test \| revert` |
+| `module` | yes | Affected product area in plain English |
+| `customer_visible` | yes | `yes \| no \| indirect` |
+| `security_relevant` | yes | `true \| false` |
+| `breaking_change` | yes | `true \| false` |
+| `severity` | bugs only | `critical \| high \| medium \| low` |
+| `feature_flag` | when applicable | Flag constant name |
+| `release_notes.audience` | yes | `customer \| internal \| both \| skip` |
+| `release_notes.priority` | yes | `high \| medium \| low` |
+
+**Markdown body** — human- and LLM-readable prose with sections chosen from a defined menu
+(`## What changed`, `## Why it matters`, `## API surface`, `## Configuration`, etc.).
+
+See `prompts/doc_object_generation.md` for the full schema, classification heuristics,
+and body-section guidance the generation model follows.
+
+## Audience filtering
+
+The `release_notes.audience` field lets downstream pipelines pull only what is relevant.
+A release-notes pipeline targeting customers excludes `audience: internal` and `audience: skip`
+entries automatically, without re-reading any diffs.
+
+## Provenance
+
+Every doc object includes a `provenance:` block stamped with the model ID, prompt version,
+and generation timestamp. This makes prompt-version upgrades auditable: regenerate with a
+newer prompt version and the `provenance` block marks the difference.
