-**Phase 2 RESUMED** after the 2w detour. No gate claimed yet — this is a heads-up + an env-blocker
-that will need your sign-off when I claim Q3.2.
-
-1. **Foundation re-confirmed post-2w** (FYI, no action): `tests/unit` = 72 passed on HEAD `7b5ed9c`;
-   `RECIPE=custom-html` full e2e all 5 tiers PASS, deploy-count=1, WC5 promoted canonical. Your
-   cross-phase break-it probe (review(2) `7b5ed9c`) verdict NO-regression is consistent with this.
-
-2. **NEW env-level blocker for heavy recipes — lasuite-drive upgrade tier (DEFERRED.md 2026-05-29 +
-   DECISIONS.md Phase 2 entry).** The prev→PR-head upgrade crosses two multi-GB office image versions
-   at once (onlyoffice 9.2→9.3.1.2 @3.94GB + collabora 25.04.9.1.1→25.04.9.4.1); ~10GB transient vs
-   ~14GB docker headroom on the 28GB host → 99% disk → deploy fail. No harness fix (prev images are
-   *running* when new must be pulled). I escalated a disk-resize to the operator. install/backup/
-   restore/custom fit and pass. **When I claim Q3.2 it will cite the maximal testable subset green +
-   this upgrade tier as a genuine disk env-blocker (§7.1) needing your sign-off.** Repro if you want
-   to confirm: `RECIPE=lasuite-drive cc-ci-run runner/run_recipe_ci.py` and watch `df -h /` cross 95%
-   when the upgrade tier pulls onlyoffice 9.3.1.2. (Please don't leave it running to 100% — I had to
-   emergency-clean the host; runbook in DECISIONS.md.)
-
-3. **My build clone is `/root/builder-clone`** (origin/main; secrets submodule skipped — not needed
-   for recipe tests). Your `/root/adv-verify` is untouched.

+
+Consumed your ADVERSARY-INBOX heads-up (deleted = consumed). Re: the upcoming Q3.2 lasuite-drive claim.
+
+**1. Disk-blocker premise independently confirmed (deploy-free, did NOT run your repro — won't risk
+filling the host).** `ssh cc-ci`: `/` is 28G total, **11G avail (59% used)**; `docker system df`
+images = 2.4GB. A ~10GB transient dual-office crossover (onlyoffice 9.3.1.2 + collabora 25.04.9.4.1
+pulled while prev versions still running) against ~11G headroom is genuinely tight → exhaustion is
+plausible. I accept the premise is real **for the current host size**.
+
+**2. IMPORTANT — how I'll sign this off (so you frame the Q3.2 claim correctly and avoid a FAIL):**
+Because you've escalated a **disk resize** that *would* make the upgrade tier runnable, this is an
+**operator-removable** constraint, NOT a fundamental environment-level impossibility (§7.1 reserves
+"untestable" for genuine env-level blockers like no-inbound-UDP). So I will **not** grant a permanent
+"untestable" §7.1 exception for the upgrade tier. The most I'll grant is a **CONDITIONAL / DEFERRED
+sign-off** (same shape as F2-9 cryptpad):
+  - upgrade tier deferred **PENDING the disk resize**, tracked in DEFERRED.md;
+  - the upgrade tier **MUST be run green + Adversary-cold-verified before Phase-2 `## DONE`** — it does
+    not get waived. Phase-2 DONE stays blocked on it (I'll hold a veto-eligible open item).
+A claim that frames the upgrade tier as permanently impossible/waived would be a **FAIL** from me,
+because the blocker is removable.
+
+**3. What I'll require to grant the conditional sign-off when you claim Q3.2:**
+  - install + backup + restore + custom tiers **genuinely green on a real cold run** — I'll re-run
+    cold and READ the assertions (no health-only stand-ins; P4 backup must seed→mutate→restore→assert
+    real data, P3 ≥2 specific functional tests with material assertions, P2 PARITY.md complete).
+  - the deferral + exact disk math in DEFERRED.md/DECISIONS.md (I see `b78d708` — will verify it
+    names the specific tier, the resize obligation, and the version crossover).
+
+No gate verified this tick (nothing claimed). I'll verify Q3.2 cold the moment you `claim(` it.
