docs(plan): record r28 - the gh stack merge of ten PRs and the baseline on main - #67

Summary

Records r28: one gh stack merge put ten PRs (#56 to #65) into main on 2026-10-31. Documents only.

main        7cb9e23 (v0.7.0)  ->  032ddbb      squash merge, UTC 03:17:44 to 03:17:54
stack #66   #58 #59 #56 #57 #60 #61 #62 #63 #64 #65        (bottom to top)

execution log   + section 10.31 (r28): the stack order, the eight rebuilt heads (old and new),
                  the conflicts and how they were solved, the checks before the merge,
                  CI on main, what is not verified
                  contents list, section 10 title and intro, revision log
plan            header, "current state", phase D row, "not in V0.6", V0.7 known issues
                next steps, "not verified yet", decisions 8, 9, 10, 14 (the status words)
                section 7: 1.P6, D.5 and D.8 (ticked), the residue numbers of phase C
                section 10 index, revision summary, link definitions
baseline        docs/baselines/tui.md: the numbers of the TUI CI run on main

What changes in the plan:

-phase D            not started
+phase D            started (D.5 and D.8 are done)
-five PRs are open, not merged
+merged into main (r28), not in v0.7.0
-[ ] D.5    [ ] D.8
+[x] D.5    [x] D.8

Evidence

• Before: docs/baselines/tui.md says 8,595 tests, leader 243, x.ai 297. The plan says that the five PRs of r27 are open.
  After: the report says 8,557 (the sum of the manifest). The TUI CI run on main, 41163765734, has 8,558 passed, 0 failed, 25 skipped, and the gates are at their ceilings (970 packages, 0 warnings, leader 239, x.ai 282). The CI run 41163765675 passes too. The difference of one test is pi-file-utils: 217 on CI, 216 in the manifest since fix(tui): read every age of the queue janitor before it deletes a file #47. The manifest is not changed here.
• Merge check: the tree of main (0cad78b) is equal to the tree of the top head of the stack (e354af5).
• Link check (scratch script): every [text][ref] of the plan has a definition; every ](#anchor) of the plan and the log has a heading; the new anchor follows the GitHub rules. gh api markdown (gfm) shows no stray ** outside code.
• ruff check and ruff format --check pass. No code changed, so no test ran.

Merge Danger

Door: two-way.

Blast Radius: documentation (three files under docs/).

The numbers in docs/baselines/tui.md come from one CI run. The release numbers (size, build time, --version latency) are still those of r21 and r22.
