Re-review of afa350d found that the correlated-subquery rewrite in
listLeads regressed any page landing in a large sort-tie block (e.g. the
default prioridade:asc sort's prioridade=4/score=0 bucket): SQLite's block
sort materializes the whole tied group before LIMIT/OFFSET apply, so the
shared-number subqueries got evaluated for the entire block instead of just
the page (measured 8-9x slower on page 2+ of a 60k-row fixture).
Split listLeads into two queries: a cheap id-only pass that does the
sorting/pagination (same cost as before the shared-number feature existed),
then a hydrate pass scoped to WHERE leads.id IN (...) for just that page's
ids, which is where the shared-number subqueries now run. getLead was
already a single-id lookup and didn't need this.
Also fixed the accompanying test, which only checked page 1 (a small,
already-sorted block) and so couldn't have caught the regression it was
meant to guard against; it now also checks a page landing inside the large
tied block.
The last-mile validator in campaign-worker.mjs revalidated opt-out/inbound/
dedupe right before sending but never rechecked shared-number state, so
re-blocking a released number after scheduling didn't stop the send.
equivalentPhoneNumbers isn't symmetric for all 8/9-digit pairs, which made
isNumberSharedAcrossLeads and listSharedNumberGroups disagree for a 12-digit
local outside the 6-9 range vs its 13-digit counterpart: one side of the pair
could be enforcement-blocked while invisible and unreleasable in the review
screen. A new canonicalPhoneKey/canonicalPhoneVariants pair in phone.mjs
(plus SQL mirrors) makes the matching relation symmetric by construction.
listSharedNumberGroups did a full leads-table scan on every listLeads/getLead
call, the app's primary paginated screen. Replaced with per-row correlated
subqueries against idx_leads_whatsapp so cost tracks the page, not the table.
normalizedSql/equivalentSql (SQL) duplicated equivalentPhoneNumbers (JS) with
no test proving they agreed; moved into phone.mjs alongside their canonical
counterparts and added tests/phone.test.mjs asserting agreement across a
shared number set, including the asymmetric case.
Tracks the app that was already in place (capture, treatment, outreach,
WhatsApp integration, server, frontend, tests, docs) so future feature
work can branch and use isolated worktrees.
