docs(drift): a remedy that landed in the suite and not in the document, parked

[JulienMartel]

What

One entry appended to docs/drift.md under Seen once, not yet a row. No row number added, the table is untouched.

A DRIFT REMEDY that lands in the suite and not in the document, so the copy a reader reaches first is the one nothing holds.

Why

haus#762 deleted the hand census of which checks CI covers and replaced it with checks-platform-split, which subtracts the two systems' attrNames. Right fix, and a check that cannot go stale. On haus 893bb427 the same exemption was still stated in words in five other places — four of them in .github/workflows/check.yml, the file a person opens to find out what CI runs — and the suite had been told about none of them. A comment beside an unrelated check in the same flake then rotted pointing at "the census", which by then named neither the list nor the check.

Parked rather than numbered: one sighting, and the numbering is frozen.

Verify

• Claims checked against haus main at 893bb427: df478382 (#762) is the only commit touching checks-platform-split; the fixture is at flake.nix:6507; the rotted pointer is at flake.nix:6785-6786; grep -c brew-bundle-guarded .github/workflows/check.yml is 4, plus flake.nix:614.
• "at least seven separate times" is attributed to haus's own comment, not asserted as a count.
• Entry wraps ≤82, the file's prose runs to 86. Trailing newline intact.
• Pre-PR assurance pass run on a clean-context subagent. It raised three findings ≥3/5 — row 20 unnamed as the nearer neighbour, a false "written down twice" count, and a Caught by that implied one fix closes the shape. All three are fixed in this branch; the entry now names both row 20 and row 33 and says the partial remedy out loud.
• scruff overlap: no other lanes on workshop.

Watch out

• The entry's first line goes stale the moment checks: check.yml's census is a fixture now, and the eval reads it haus#769 merges — it is anchored on 893bb427 for that reason, and drift.md's exemption for "used to / no longer naming a shape" is what keeps the past tense legal here.
• A second sighting promotes this to row 35 and deletes the entry, per the section's own contract.
