# test-wake-digest-quarantine.sh — RED-FIRST invariant harness for #920 (EPIC
# #892): per-entry QUARANTINE of a render-refused digest entry (no head-of-line
# blocking) + reconciler ENUMERATIONS render ORIENTATION-tier.
#
# Each test asserts ONE invariant and goes RED against the pre-#920 digest.sh:
#   Q1 (a) QUARANTINE + REST-DELIVERS: a malformed `actionable` carrying the live
#          pilot's EXACT locator shape {kind,id,path,observed_hash} (no hard
#          locator, no reconciled marker) is DEAD-LETTERED + alarmed AND EXCLUDED,
#          while a clean valid sibling in the SAME drain still renders (exit 0).
#          RED baseline: the old whole-digest exit-4 delivered NOTHING (the live
#          head-of-line-blocking wedge).                                    (#920 FIX1)
#   Q2 (b) ENUM-AS-ORIENTATION: a reconciler enumeration (locators.reconciled==
#          true) renders as an ORIENTATION-tier pointer and does NOT exit-4 / is
#          NOT quarantined. RED baseline: reconciled `actionable` + soft locators
#          {kind,id,path,observed_hash} -> exit-4.                          (#920 FIX2)
#   Q3 (c) TWO DISTINCT ENUMERATIONS BOTH SURVIVE: two distinct enumerations both
#          render as SEPARATE orientation pointers (neither coalesced away) — the
#          anti-collapse proof pinning the amended ruling (the REJECTED class=digest
#          would have collapsed them to one; store class stays non-coalescing). (#920 FIX2)
#   Q4     PRESERVED ACTIONABLE FAIL-LOUD: a genuine malformed ACTIONABLE claim
#          (no reconciled marker, no hard locator) is STILL loudly surfaced
#          (dead-letter + alarm) and NEVER delivered as if valid — fail-loud is
#          preserved, now per-entry.                                        (§2.1)
#   Q5     CLAIM-PRECEDENCE GATED: a non-actionable-class entry that carries a
#          `claim` (a consequential fact) with no hard locator is STILL gated
#          (quarantined), and the reconciled exemption does not leak to it.  (§2.1)
#
# Hermetic: feeds controlled JSONL via `digest.sh render --from-file` — NO store,
# NO network, NO openssl (so it runs identically under the CI openssl-mask).
#
# Each test runs in its own (..) subshell for env isolation; the per-subshell
# WAKE_STATE_HOME export is intentional (mirrors test-wake-reconcile.sh).
