* fix: gate a warmup partner borrowed from the other tier against the pool it is in rather than the sender's, since the thin-tier fallback had rejected every borrowed candidate and a thin tier failed instead of borrowing
* fix: make cross-tier warmup borrowing one-directional and gate borrowed partners in their own pool, so a thin premium tier can actually borrow proven free mailboxes (#495)
* fix: pin the borrow floor at the exact boundary so a premium tier at the floor including its sender still borrows (#495)
* fix: put the warmup borrowing rule in one repository method (direction, floor, proven age, workspace standing) that the selector and scheduler both read, pin every drawn partner's gate to its own pool, fall through buckets when a stale row fails the gate, and allow only reply-backs across tiers (#495)
* fix: end the warmup partner draw by candidate exhaustion instead of a fixed attempt cap, and fail closed when a free mailbox's workspace standing cannot be read before it answers into a paid inbox (#495)
* fix: end the warmup partner draw by candidate exhaustion instead of a fixed attempt cap, and fail closed when a free mailbox's workspace standing cannot be read before it answers into a paid inbox (#495)
* feat: give a cold mailbox a rotation lifecycle so a tired one can rest and come back, instead of running at full volume until a hard band trips: send_lifecycle is warming, active, resting or reserve and decides whether cold sender resolution offers the mailbox at all, which is a different axis from risk_band deciding which worker and IP host it, so a resting mailbox is still a clean-band mailbox that keeps its warmup traffic and its reputation; the hourly rebalancer rests a mailbox at throttled and worse but never at watch, since watch is defined as the band that changes nothing a customer can feel and leaving cold rotation is very much something they feel, and a rested mailbox returns only after three clean days so one good hour cannot bounce it back to full volume; reserve is the owner's hold and is never overridden, the default is active so no existing mailbox changes on deploy, and the state never travels in a workspace archive because it is this instance's decision about sending it watched
* feat: stop a query error re-admitting rested mailboxes, make probation measure healthy time, and rotate the candidate window so no mailbox starves: sendLifecycles returned a nil map on failure and an unresolved state reads as active, so one bad query quietly put every resting and reserved mailbox back into cold rotation, and the gate is now applied only when the states were actually read, with the skip logged rather than silent; ReadyToResume measured total time resting, so a mailbox that sat unhealthy for three days resumed on its first healthy tick having served no clean time, and an unhealthy evaluation now restarts the streak; and ordering candidates by send_lifecycle_since put every never-moved mailbox equal-first, so on an install with more than one page of them the same page was re-examined forever, which a checked-at stamp and its index fix
* feat: give an organization one fused abuse posture, because every existing control watches a single subject and an actor slightly wrong on several axes sits under all of them: organizations gains risk_state, risk_score, risk_reason and an append-only risk_signals evidence blob, modelled on the warmup participant health machine that already works rather than a second vocabulary for the same idea; restricted cuts per-mailbox cold volume to a quarter and forces the free warmup pool so a risky tenant cannot spend the paid pool's shared reputation, suspended stops sending at the send gate, and watch deliberately changes nothing a customer can feel so evidence accumulates before anything is taken away; an operator's suspension outranks the derived band so a detector clearing cannot release a workspace a human suspended, transitions ride the audit spine to every teammate's dashboard, a banner says which limit is active and why rather than letting volume drop silently, and the posture never travels in a workspace archive since it is one platform's verdict reached from evidence the destination never saw
* feat: make the suspension actually stop sending, and emit the audit transitions the PR claimed: emailsend.SendEmail is only the manual and API path, so campaign and warmup sends went nowhere near the gate and a suspended workspace kept sending on its schedule, while the restricted multiplier floored every mailbox at one a day which quietly turned suspension into a trickle rather than a stop; the campaign scheduler now defers the whole campaign with a reason and the warmup task skips as org-suspended, since warmup is outbound mail from the same domains; separately the band change emitted no audit entry at all despite the entity type and the frontend spine entry both existing, so no banner moved for a teammate and there was no trail of who was restricted when, and only a real transition is logged so a detector re-recording the same finding cannot fill the feed; one of my own live tests also asserted how far out a slot lands, which depends on the hour the suite runs, and now asserts the property it was about
* chore: drop a test that belongs to the signup-risk change and reached this branch by mistake, where the type it exercises does not exist
* feat: ease a graduating mailbox into cold volume instead of handing it the full cap the day it joins a campaign: cold sending read warmup HEALTH but never whether the mailbox had actually warmed enough, so one at its 40/day warmup ceiling could send 50 cold the next morning, which is the post-warmup spike providers penalise; effectiveCap gains a min() term that starts the mailbox at 5, 10 or 20 a day by how long it warmed and adds 5 per clean day toward its own cap, freezing on a spam placement through the same union-of-freezes the warmup ramp uses, anchored by a new cold_ramp_started_at stamped idempotently on the first cold send and reset on org import because it raises a ceiling the destination never watched being earned; mailboxes that never warmed are not gated, since capping senders who never opted into warmup is a different decision from smoothing the transition out of it
* feat: anchor the graduation ramp on a CONFIRMED send, and make the hold the drawer reports the hold the scheduler applies: stamping cold_ramp_started_at at dispatch started the clock on a send the worker then failed, so a mailbox climbed on days it had not proven anything, and the stamp moves to the worker's EMAIL_SENT; separately the drawer computed its hold over every placement while ColdCeiling only counts placements after the first cold send, so a placement predating the ramp read as paused while the scheduler kept climbing, and both now go through one ColdHeldUntil
* fix: restore the Callout closing tag my conflict resolution dropped, which types:check and lint both pass and only pnpm build catches
* feat: let a warmup recipient answer the mailbox that just wrote to it, so a thread reads as a conversation rather than two mailboxes monologuing on their own ramps: warmup_tasks.target_account_id was written as nil and never read by anything, so a reply only happened when the recipient's own ramp fired AND the draw happened to land on that partner; a verified receipt now sometimes re-points the recipient's pending warmup task at the sender 25 minutes to 5 hours later inside its own warmup hours, which is a re-pointing rather than new work because only one warmup task may be pending per mailbox, it can never delay a send the mailbox had planned sooner, and it stops before the thread cap so replies cannot answer replies forever; the clock parser also moves into models.ClockMinutes so a second copy of the HH:MM parsing that silently disabled every sending window cannot drift back in
* feat: stop the reply-back drawing the reply rate twice, and stop its jitter escaping a short warmup window: the scheduler drew the recipient's reply rate to decide whether to answer at all, then the task handler drew it again to decide reply-versus-new, so a 30 percent reply rate produced a 9 percent answer rate and a directed task could send a fresh message to the mailbox it was meant to be answering; a directed task now IS the reply, and the opening-time jitter is capped to the window width so a mailbox warming 09:00 to 09:20 is not scheduled past its own close
* feat: close the warmup ramp loop so an early spam placement holds the mailbox instead of letting it climb into the wall: every band in evaluateMetrics needs a sample floor before it can trip (20 warmup sends in 7 days, 100 delivered in 30), which a mailbox in its first fortnight never reaches, so one landing in junk on day three kept adding an email a day until it had sent enough to be judged; a placement inside 48h now cuts the day about a quarter and holds the ramp where it stood, and the resume subtracts the frozen days rather than catching them up because climbing three steps in one morning is the spike the hold exists to prevent; the ramp arithmetic moves into internal/app/warmupramp so the mailbox drawer reports the target the scheduler will actually act on instead of its own private copy, and says which signal cut it and when it resumes
* feat: fix three defects the review found in the warmup ramp hold: the ramp is now elapsed days minus frozen days rather than a level held at the newest placement, because MAX(created_at) meant a second placement arriving mid-hold RAISED the held level and a mailbox landing in junk repeatedly ramped up; the early-signal cut and the health band are resolved in one shared warmupramp.Resolve so the scheduler's health gate and the dashboard's ungated copy can no longer disagree about the same mailbox; and the hold is reported for the whole 72h freeze instead of only the 48h cut window, so a mailbox between the two no longer shows a ramp that has stopped climbing with nothing to explain it
* feat: make send-time optimization actually schedule sends, instead of being a documented setting with no caller: advanced.OptimizeSendTime had zero call sites anywhere in the codebase, so an org that enabled send_time_optimization through PATCH /outreach/settings changed nothing about when its campaign mail left, and the API reference said so in a callout; the campaign scheduler now resolves the recipient's timezone from the contact's timezone custom field, then the country-code suffix of its email domain, then the org fallback, and holds the slot until that clock reaches a preferred hour, raising hardFloor so the task handler reschedules rather than sending immediately, the snap is forward-only and never crosses the campaign end date, the default flips to off so no existing workspace silently re-times its sends, and Settings > Sending gives the block its first UI
* feat: stop the recipient-hour gate deferring a send forever, and fix the window parser that silently disabled every campaign schedule: recipientSlot now searches for a moment BOTH calendars accept and yields when they never meet, because raising a hard floor at an hour the sender cannot serve made every tick re-derive it, defer, wake in the sender's window and defer again; separately parseTimeOfDay accepted only the 15:04 layout while start_time, end_time, warmup_start_time and warmup_end_time are Postgres time columns pgx renders as 09:00:00.000000, so every read parsed to 0 and effectiveWindows read that as unconstrained, leaving both the campaign sending window and its day-of-week gate off for every campaign on the legacy fields and pinning warmup to its 08:00-20:00 fallbacks; Settings > Sending also gains the MANAGE_SETTINGS gate a direct visit needs
