Goal And Delivered Outcome

• Outcome basis / optional anchor: the nightly Full Public Smokes docs-governance-smoke.py failure introduced by RFC: joint target/yardstick selection with lightweight Stride decisions #8105.
• Goal/source and gap: target-yardstick-stride-decisions-v0 was merged without the bilingual semantic-mirror markers the governance check requires. Before: docs-governance-smoke.py exits 1 with AssertionError: target-yardstick-stride-decisions-v0.md, then with the zh-CN mirror. After: it prints docs-governance-smoke ok.
• Observable before → after, with the validation row that proves it: python3 examples/docs-governance-smoke.py fails on the missing semantic mirror / 语义镜像 markers; after this change it passes.
• Issue/task and intended base: no issue; self-contained maintenance repair. Intended base is loopx-project/loopx:main.

Author Declaration

• Written by: model_agent — Qoder AI assistant, at the contributor's direction; no human review has occurred.

Implemented against

• Specification and revision: examples/docs-governance-smoke.py at 4d8b79692d13ea17a43d2369d35282b023be311e, checks at lines 202-203; the merged RFC from RFC: joint target/yardstick selection with lightweight Stride decisions #8105.
• Criteria:

Criterion (spec clause)	Disposition	Symbol / path	Test or command
English RFC contains semantic mirror	implemented	docs/architecture/rfcs/target-yardstick-stride-decisions-v0.md:11	python3 examples/docs-governance-smoke.py
Chinese RFC contains 语义镜像	implemented	docs/architecture/rfcs/target-yardstick-stride-decisions-v0.zh-CN.md:11	same
Reciprocal language links remain intact	implemented	both header lines	python3 scripts/check_rfc_bilingual.py --base upstream/main --head HEAD

• Self-check before submission: read both RFC headers and the governance check, changed only the two header labels, ran the governance smoke and the bilingual premerge check. No runtime or semantic RFC content changed.

Scope And Continuation

• Completed scope and remaining work: complete within this scope; no runtime behavior changes.
• Slice boundary / successor: N/A — the two header markers are the whole exit.

Validation

• Tested revision: 0cbbbc642a5cf99d8078927735450538d559d85c
• Run state: finished
• Input classes: synthetic

Check kind	Result	Public-safe evidence / limitation
integration	passed	python3 examples/docs-governance-smoke.py → docs-governance-smoke ok.
regression_parity	passed	The same command fails on base 4d8b79692d13ea17a43d2369d35282b023be311e with the missing-marker assertion and passes on this head.
static	passed	git diff --check; python3 scripts/check_rfc_bilingual.py --base upstream/main --head HEAD → RFC bilingual diff check passed.
unit	not_run	Docs-only; no unit test covers RFC header text.

• Coverage and gaps: documentation-only; no runtime surface changed. The nightly workflow is intentionally not a PR-required check, so no hosted CI run is attached to this diff.

Boundary Checklist

• Neither the diff nor this PR body/comments/attachments disclose private state, credentials, raw traces or verifier output, internal links, or local machine paths (including .loopx/, .codex/goals/, and live ACTIVE_GOAL_STATE.md).
• I did not duplicate maintainer-owned benchmark work unless a maintainer split out a public issue for it.
• I kept the change scoped to the linked issue/task.
• Existing English/Chinese RFC pairs both have a diff, and python3 scripts/check_rfc_bilingual.py --base upstream/main --head HEAD passes.
• I completed the visual evidence section for UI changes, or marked UI impact none.
• Every commit includes a DCO Signed-off-by trailer (git commit -s).
