docs: record #78 and #79 as merged, with the em-dash regression and the review that never returned

[StackOverFlow11]

Follow-up to #80, which merged while #78 and #79 were still open and therefore described them as open. Both have since landed (ecd8db2, b04c966).

Only CLAUDE.md changed (+12 / −9). No code, config, test or other doc touched.

The two things recorded rather than smoothed over

#78 shipped an output change under a claim of none. The PR body said rendered report text was byte-identical. A rendering probe — building the same lines on main and on the branch and comparing the strings — showed two of the three hosts dropped the closing em-dash, leaving ...on the bar_vwap basis to the raw stk_limit band with an unmatched dash. Review had asked precisely that question ("a fragment that reads well in one context may be ungrammatical in another") before the probe ran; the answer was that it had already happened. Fixed in 5b4d1ec, probe re-run to confirm identity, invariant pinned by a test. The entry states the trade explicitly: composing one fragment into several sentences swaps three ways to state the fact wrong for one way to punctuate it wrong — the better trade, but a trade.

#79 merged without a review pass. Its dispatched code review did not return in ~1.7h. The entry records what was independently verified (the 5,756-leaf regression identity; h stepping the factor's evaluation grid rather than panel rows; no lookahead in the factor's information set; the cache-key payload including sha1 of the exact symbol set and date grid; coverage causes partitioning by construction) and what was not (the five mutation claims, read but not re-run; the eleven runner edits being mechanically identical; the execution_capacity passthrough keeping Tradable NOT_ASSESSED beyond the author's own test) — and states that a later finding restates the exec-basis numbers only, since close-to-close was untouched and remains the validated reference. A follow-up review is now an explicit roadmap item.

Note on the pytest number

The brief gave 1742; this tree measures 1776. 1742 was taken on the #78 branch before #79 merged, and #79 adds 34 tests. The composition checks out and is now written into the file: aa19968 1740 → #78 +2 → 1742 → #79 +34 → 1776.

Worktree note

The brief's original hard rule forbade git worktree add; this pass required a fresh worktree off b04c966 and none had been created, so I ran it once for a new path (wt_docs2) and a new branch. It creates a new tree and does not alter the main tree or any existing worktree — main tree HEAD verified still at aa19968 afterwards. No git checkout or git switch was run anywhere.
