fix(inspect): trim before the framing check; stop advisories swallowing the backstop (#556); pin the MQTT payloadFormat mode contract (#557 item 2)
#556 item 1 — leading whitespace defeated every Inspect's pre-filter. Seven factories (Modbus/S7/AbCip/AbLegacy/TwinCAT/FOCAS/Mqtt) tested `reference[0] != '{'`, so a padded blob returned EMPTY and a tag the driver refuses deployed clean. The check now trims first, matching the idiom Sql/Calculation/MTConnect/OpcUaClient already used. The raw reference is still what is handed to the mapper — the driver reads the stored blob, not a trimmed copy — so the gate keeps mirroring the runtime rather than becoming lenient. Both directions are pinned: a padded blob the mapper accepts still draws nothing, and one that is not object-framed AFTER trimming still draws nothing (it is not an equipment-tag TagConfig at all). Six of the seven mappers hand the blob to a whitespace-tolerant JsonDocument.Parse, so their verdict is unchanged by padding. MQTT is the exception: both its readers carry the same framing gate, so a padded blob is genuinely refused — which is why the untrimmed pre-filter was a real defect there and not a cosmetic mismatch. #556 item 2 — FOCAS and MQTT appended advisories unconditionally and then gated the catch-all rejection message on `warnings.Count == 0`, so an advisory (which fires on ACCEPTED blobs too, and says nothing about a refusal) silently swallowed the only message naming a refusal nothing else can. The two classes now accumulate in SEPARATE lists and the backstop gates on the rejection count alone — structural, not string matching. MQTT's swallow was reachable in production (a padded blob its readers refuse while every describe branch finds the parsed document well-formed); FOCAS's backstop is currently unreachable by audit, so its guard is protective. #557 item 2 — decided and pinned: KEEP the union verdict. Evidence: FromSparkplugTagConfig hard-codes PayloadFormat=Json and never consults the key; only MqttSubscriptionManager (the Plain ingest path) decodes by it; and MqttTagConfigModel.ToJson deliberately omits the key entirely in Sparkplug mode (#513). So a Sparkplug driver genuinely serves the tag and rejecting it would be stricter than the runtime. The cost — served behaviour depends on the driver's MqttMode, which no tag row records — is paid by an ADVISORY naming the key and the mode dependency, not by changing the verdict, so both gates keep agreeing. The same invalid value on a blob the union REFUSES stays a rejection; the class is decided by the accept gate, never by the key. Falsified: reverting Modbus's trim reddens the padded-rejection theory; neutering MQTT's backstop guard to the pre-#556 shape reddens the advisory-plus-unnameable-rejection test; disabling the #557 advisory reddens the contract pin; and for FOCAS, removing a describe branch alone stays green (the backstop covers it) while additionally neutering the guard goes red.
