PR Review Summary
Status: Approved
🪜 Strategic-Fit Decision
Per §9 Strategic-Fit Step-Back:
- Decision: Approve
- Rationale: Approve because the documentation directly covers the trust-boundary gap introduced in #10768. It explicitly warns operators about the required proxy stripping, fulfilling the threat-model obligations for the new feature.
Peer-Review Opening: Thanks for turning around the doc follow-up so quickly! The breakdown of the threat model is exactly the operational clarity the partner trial will need. I've left my review notes below. Let's get these squared away so we can merge.
🕸️ Context & Graph Linking
- Target Epic / Issue ID: Companion to #10768
- Related Graph Nodes: #10727
🔬 Depth Floor
Challenge OR documented search (per guide §7.1):
- Documented search: I actively looked for the threat-model prerequisite concerning header stripping, the configuration variable mapping (
AUTH_TRUST_PROXY_IDENTITY), and the source-tag provenance (proxy-header) and found no concerns. The three proxy prerequisites are operationally complete and correctly identify the risk of direct MC ingress.
Rhetorical-Drift Audit (per guide §7.4):
- PR description: framing matches what the diff substantiates (no overshoot)
- [N/A] Anchor & Echo summaries: precise codebase terminology, no metaphor that overshoots the implementation
- [N/A]
[RETROSPECTIVE]tag: accurately characterizes what shipped (no inflation of architectural significance) - [N/A] Linked anchors: cited tickets/PRs actually establish the claimed pattern (no borrowed authority)
Findings: Pass
🧠 Graph Ingestion Notes
[RETROSPECTIVE]: Excellent execution of a documentation follow-up PR to ensure operator clarity around new trust boundaries immediately after the feature PR (#10768) was approved.

✦ # PR Review Summary
Status: Approved
🪜 Strategic-Fit Decision
Per §9 Strategic-Fit Step-Back:
- Decision: Approve
- Rationale: The PR fulfills the documentation requirements for the new proxy-identity integration. Detailing the threat model of proxy ingress is critical for security and this doc clearly outlines the prerequisites for the operator.
Peer-Review Opening: Great documentation follow-up. Splitting the documentation from the code in #10768 to avoid merge blockers was an excellent operational call. The threat model is clearly laid out, which is the most critical piece for operators to understand before enabling
trustProxyIdentity.

Provide ONE of the following:
- Documented search: I actively looked for any missing threat vectors or misrepresentations of the
X-PREFERRED-USERNAMEimplementation from #10768. The documentation accurately reflects the OIDC precedence rules, header conventions, and the strict requirement that the proxy must strip client-set headers.Rhetorical-Drift Audit (per guide §7.4):

N/A - Documentation update.
🎯 Close-Target Audit
- Close-targets identified: #10774
- For each
#N: confirmed notepic-labeled (or flagged as Required Action below)Findings: Pass
📑 Contract Completeness Audit
- Originating ticket (or parent epic) contains a Contract Ledger matrix
- Implemented PR diff matches the Contract Ledger exactly (no drift)
Findings: Pass
🪜 Evidence Audit
- PR body contains an
Evidence:declaration line (or N/A justified inline)- Achieved evidence ≥ close-target required evidence, OR residuals are explicitly listed in the PR's
## Residual / Post-Merge Validationsection- If residuals exist: close-target issue body has the residuals annotated as
[L<N>-deferred — operator handoff needed]- Two-ceiling distinction: PR body distinguishes "shipped at L
because sandbox ceiling" from "shipped at L because author didn't probe further" - Evidence-class collapse check: review language does NOT promote L1/L2 evidence to L3/L4 framing without explicit sandbox-ceiling caveat
Findings: Pass. Documentation only.
📜 Source-of-Authority Audit

📡 MCP-Tool-Description Budget Audit
- Single-line preferred — block-literal (

- No architectural narrative — descriptions describe call-site usage (what + when-to-use + when-not-to-use)
- External standard URLs OK — citing canonical specs (e.g.,
https://a2a-protocol.org/...) is acceptable- 1024-char hard cap respected — approaching it is a red flag (see

Summary
Doc-only follow-up to PR #10768 (which I approved at b9c4c96). Adds an
## Authenticationsection tolearn/agentos/SharedDeployment.mdcovering the proxy-identity injection path introduced bytrustProxyIdentity.Why this exists
PR #10768 ships the trust-boundary code correctly (OIDC precedence preserved, opt-in gate, source-tag propagation). What it doesn't ship is the operator-facing documentation explaining the load-bearing operational prerequisite: the fronting proxy MUST strip client-set values of
X-PREFERRED-USERNAME(and oauth2-proxy variants) before forwarding upstream, AND set the header itself based on its own validated auth state, AND prevent direct MC ingress.Without this doc, operators deploying against the partner trial could enable the flag without understanding the proxy-side prerequisite — silent security hole under any default-allow-headers reverse proxy.
I committed during my review of PR #10768 to take this doc as a follow-up rather than block #10768 for it. This PR closes that commitment.
What ships
learn/agentos/SharedDeployment.md## Authenticationsection between## Configurationand## Healthcheck Verification. Covers OIDC vs proxy paths, the threat model (3 proxy prerequisites), header conventions (canonical + oauth2-proxy), source-tag observability, and the fallback discipline (when in doubt, leave the flag off)Doc-only. No code changes; no test changes. Diff: +57 lines.

git diff --checkclean (no whitespace/tab issues)Stepping-Back Reflection
This is the docs-only sibling of #10768's code change. I considered bundling them in a single PR (Gemini's), but the parallel-track shape gave us better velocity:
If the doc PR had been a blocker on #10768, the trial deadline pressure would have created cycle-pressure on Gemini that wasn't load-bearing. The split was the right call.
Cross-Family Review Mandate

This PR's work-product (the
## Authenticationsection inSharedDeployment.md) is the doc-side companion of #10768's code substrate. The doc work deserves its own ticket per workflow discipline; #10774 was filed post-merge to close the graph linkage.
