Subject: [PATCH] Cell C has a gate now: the composite must filter, not
 navigate
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The claim worth testing about the composed dashboard is not that it renders. It
is that it keeps the reader INSIDE it. Standalone, "Every resource in
<language>" is a link to the tables page; composed, it must be a button that
filters in place, because navigating away throws out the map the reader just
positioned and the group they just found. Same words, two affordances, one right
in each context.

Six assertions, each a way the composite can look fine and be broken: the
control is a <button> not an <a>, the URL does not change, the table's row count
goes DOWN, it does not go to zero, the pin count survives, and nothing 4xx'd or
threw.

It picks its subject from the live source rather than by position, and that is
not a detail. The first run opened pin 0 — Abai Sungai, a group with nothing
found — so the filter correctly produced an empty table and the check failed a
working composite. The test was wrong, not the product. It now opens a tier-2
pin, so "narrowed but not emptied" is a question the subject can answer.

Measured: 2,107 pins and 50 rows before, then Telugu narrows the tables to 13
with the map intact and the URL unchanged.

+/**
+ * check-gospel-composed-filters.mjs — cell C: the map COMPOSED above its own tables.
+ *
+ * THE CLAIM UNDER TEST is not "it renders". It is that the composite keeps the reader INSIDE
+ * it. Standalone, the sheet's "Every resource in <language>" is a LINK to the tables page.
+ * Composed, it must become an in-place FILTER, because navigating away throws out the map the
+ * reader has just positioned and the group they have just found. Two different affordances
+ * behind the same words, and only one of them is right in each context.
+ *
+ * WHAT IT ASSERTS, and each one is a way the composite can look fine and be broken:
+ *   - the control is a <button>, not an <a>          (a link here navigates)
+ *   - the URL does not change                        (proves it did not navigate)
+ *   - the table's ROW COUNT goes down                (proves the filter reached the data)
+ *   - the row count stays above zero                 (proves it filtered rather than emptied)
+ *   - the pin count is unchanged                     (proves the map survived the click)
+ *   - no response >= 400 and no page error           (proves it did not paper over a failure)
+ *
+ * IT PICKS ITS SUBJECT FROM THE DATA, and that is not a detail. The first run of this check
+ * opened pin 0 — Abai Sungai, a group with NOTHING found — so the filter correctly produced an
+ * empty table and the check failed a working composite. The test was wrong, not the product.
+ * It now selects a tier-2 pin from the live source, so "rows went down but not to zero" is a
+ * question the subject can actually answer.
+ *
+ * BROWSER GATE. Run it under both rendezvous locks, product lock first — the fixed order is
+ * what makes the pair deadlock-free:
+ *     flock -w 1200 <product-lock> flock -w 1200 <agent-lock> bun run check:composed-filters
