v0.194.0 — one operator email per backup run, and nothing dropped without a trace (R-182)

MEASURED, not supposed. On 2026-08-03 nine per-app recovery_unit_capture_failed
events reached the hub and TWO operator emails went out. The hub's operator
cooldown key is customerID:eventType(+tier) and that event carries `app` but no
`tier`, so the key held no app identifier: the first refused app took the hour's
slot and every other app's failure was discarded BEFORE anything was written
down, leaving no row on any channel.

The obvious fix — put `app` in the key — was ruled against: on a full disk it
produces one email per app, the volume problem wearing the correctness problem's
clothes.

internal/backup/runsummary.go: a per-run collector with exactly admissionSet's
lifetime, fed by all three write legs, emitting backup_run_failures ONCE at the
end and only when something failed. A clean run emits nothing.

The per-app event stays and becomes the RECORD — the hub routes it record-only,
stored and logged every time, never competing for an email slot. The record and
the notification are now different things.

Deliberate skips (disconnected, decommissioned) are excluded: they have their
own alert, and a nightly email about an unplugged drive is one the operator
learns to ignore.

A manual run always reports: the digest carries a unique run_id the cooldown
cannot collapse. Someone pressing the button is actively trying to get a backup.

THE PERIODIC SWEEP GETS A DIGEST TOO. With the per-app event now record-only, a
capture failure found between runs would be recorded and never notified — a new
silence introduced while closing one. That path emits a digest with NO run_id,
so the ordinary 1-hour cooldown caps it exactly as before while the mail now
lists every failing app instead of whichever was first.

A refusal is recorded ONCE, where the verdict is taken, not at the three legs
that consult it — R-181's contract is one verdict per app per run. Noting it per
leg listed one refused app three times and produced "2 of 1 apps failed". Found
by the digest's own test, not in review.

Silence is safe because the hub's deadline check raises expected_backup_missed
from report freshness, independently of any mail this box sends
(monitor/deadline.go:396,417). Confirmed, not assumed.

7 new tests, 4 red-proofs. The main.go seam walk did NOT fail on its first
attempt — the AST test walked the backup package and not main.go; the test was
fixed and the mutation re-run rather than the pass recorded.

 ## Changelog
 
+### v0.194.0 — one operator e-mail per backup run, and nothing dropped without a trace (2026-08-03, R-182) — MinAgent: none
+
+**The defect, measured rather than supposed.** On 2026-08-03 nine per-app
+`recovery_unit_capture_failed` events reached the hub and **two operator e-mails went out**. The hub's
+operator cooldown key is `customerID + ":" + eventType + tier-suffix`, and that event carries `app`
+but **no `tier`** — so the key held no app identifier. The first refused app took the hour's slot and
+**every other app's failure was discarded before anything was written down**, leaving no row on any
+channel. A machine deciding not to tell you and nothing happening at all looked identical.
+
+**The obvious fix was ruled against, and the reason is worth keeping.** Putting `app` into the key
+fixes the swallowing by producing **one e-mail per failing app**, which on a full disk is a dozen —
+the volume problem wearing the correctness problem's clothes.
+
+**What ships instead: ONE digest per run, and every failure recorded when it happens.**
+
+- **`internal/backup/runsummary.go`** — a per-run collector with exactly `admissionSet`'s lifetime
+  (created where the run begins, cleared when it ends), fed by all three write legs. It emits
+  `backup_run_failures` once at the end, **only when something failed**. A clean run emits nothing —
+  not an empty digest.
+- **The per-app event stays and becomes the RECORD.** The hub now routes it *record-only*: stored and
+  written to the notification log every time, never competing for an e-mail slot. The record and the
+  notification are now different things, which is the durable half of this change.
+- **Deliberate skips are not failures.** A disconnected or decommissioned drive has its own alert and
+  is excluded, because a nightly e-mail about an unplugged drive is one the operator learns to ignore.
+- **A manual run always reports**, even if the nightly one already wrote that hour: the digest carries
+  a unique `run_id` that the hub's cooldown cannot collapse. Someone pressing the button is actively
+  trying to get a backup.
+
+**THE PERIODIC SWEEP GETS A DIGEST TOO, and that is not symmetry for its own sake.** `GetFullStatus`
+captures units outside any run. With the per-app event now record-only, a capture failure found
+between runs would have been recorded and **never notified** — a new silence introduced while closing
+one. So that path emits a digest as well, deliberately with **no `run_id`**, so the ordinary 1-hour
+cooldown caps it exactly as before while the mail now lists *every* failing app instead of whichever
+one happened to be first.
+
+**A refusal is recorded ONCE, where the verdict is taken**, not at each of the three legs that consult
+it — R-181's contract is that one verdict covers all three. Noting it per leg listed a single refused
+app three times and produced counts like *"2 of 1 apps failed"*. **Found by the digest's own test, not
+in review.**
+
+**Why silence is safe, checked rather than assumed.** A digest is only safe if the absence of a mail
+cannot mean "the run never finished". It cannot: the hub's daily deadline check raises
+`expected_backup_missed` / `expected_dbdump_missed` (`hub/internal/monitor/deadline.go:396,417`) from
+the box's **report freshness and stored events**, independently of any mail this box chooses to send.
+
+**Tests: 7 new, plus 4 red-proofs demonstrated failing then restored.** One of them —
+the `main.go` seam walk — **did not fail on its first attempt**, because the AST test walked the
+backup package and not `main.go`; the test was fixed and the mutation re-run rather than the pass
+being recorded.
+

+// the hub and TWO operator e-mails went out. The hub's operator cooldown key is

+// WHY NOT JUST PUT THE APP IN THE KEY. That was the obvious fix and the operator ruled against it:
