docs: lead decisions 136 (CI changes) and 137 (doc-only findings don't block)

Jason's 17:16Z rulings, relayed by Mos: the #271 CI steps (Vikunja
#273-#278) and Q143. Decision 137 is the reviewer rule for Vikunja #279;
the queue README's verdict paragraph points to it.

+136. **CI changes from the #271 debate (2026-10-14, Jason's ruling at
+    17:16Z, relayed by Mos).** Jason: "I agree with the recommended steps
+    for CI improvement." Sage's sage-0178 adoption stands, item 5
+    included as deferred. Mos filed the work on Vikunja P19:
+    - #273: builder rounds may be targeted. They run the changed
+      packages, the packages that import them, and every
+      `scripts/test-*.sh` that reads a changed path, listed in build.md.
+      Sage's landing gate stays full.
+    - #274: the landing gate drops its pkg-queue step, because
+      `scripts/test-queue.sh` runs `packages/queue/tests/` itself (9 test
+      files, 156 tests).
+    - #275: queue revs are committed at a landing, or when a seat needs
+      them pushed, not after every move.
+    - #276: a doc-only round needs no gate. A round is doc-only when every
+      path it changes is a `.md` file that no package test and no
+      `scripts/test-*.sh` reads.
+    - #277: the flaky tests get rows, then the worker trial.
+    - #278: rows that are ready together land through one batch gate.
+      Rows that share a path go in separate batches.

+137. **Doc-only review findings don't block (2026-10-14, Jason's answer
+    to Q143, "Q143: yes", relayed by Mos; Vikunja #279).** This applies
+    to every reviewer: Filbert, Dewey, Rocko, Sage and any later seat.
+    - A finding is doc-only when every path it names passes decision
+      136's #276 test: a `.md` file that no package test and no
+      `scripts/test-*.sh` reads. Check with `grep -rlF <basename>
+      packages/*/tests scripts/test-*.sh`. Any hit makes the finding
+      blocking. Tests read the PRD (`docs/prd/mosaic-stack.md`) and
+      QUEUE.md, so findings on them block. A row's brief is pinned by
+      blob in `queue.json`, so a wrong brief gets a new revision from
+      Sage, not a follow-up commit.
+    - Doc-only findings alone don't stop an approval. The reviewer records
+      `approve` and lists them in the verdict comment under "Doc-only,
+      follow-up". A round with any other finding records `changes`, as
+      before, and lists its doc-only findings too.
+    - The builder fixes them in a follow-up packet after the landing.
+      Sage lands it as its own commit with no gate (#276), and tracks it
+      in the row note until it lands. The reviewer checks the follow-up
+      only if the fix changes meaning, and says so in the verdict.
+    - Findings on code, tests, contracts, roles, schemas or any file a
+      test reads still block. A missing test the brief asks for is a code
+      finding.
+    - When unsure, the reviewer calls it blocking and says why. Sage can
+      move it down.
