Merge R2-07 Surgical pure-adds (arch-review round 2) [PR #436]
v2-ci / build (push) Successful in 3m19s
v2-ci / unit-tests (push) Failing after 8m13s

Finding 03/P1: surgical in-place address-space adds/removals skip full rebuilds
(AddressSpaceChangeClassifier default-closed to Rebuild). 3 new
ISurgicalAddressSpaceSink remove members, guard-first + forwarded through
DeferredAddressSpaceSink (F10b inertness net green). T5/T6/T12/T14 over-the-wire +
docker-dev gates deferred. Auto-merged OtOpcUaNodeManager.cs with R2-08; verified
OpcUaServer.Tests 341/341 + forwarding guard 3/3. Build clean.

New pure `AddressSpaceChangeClassifier` routes each deploy delta to its minimal mutation in `AddressSpaceApplier.Apply`: **PureAdd/AttributeOnly** skip `RebuildAddressSpace` (the idempotent Materialise passes add exactly the new nodes; `AnnounceAddedNodes` fires a Part 3 NodeAdded per parent), **PureRemove/AddRemoveMix** tear down only the affected subtree in place via 3 new `ISurgicalAddressSpaceSink` remove members (guard-first, negative-control observed) + `OtOpcUaNodeManager` scoped teardown with `NodeDeleted` model-change, and **Rebuild** stays the default-closed safety valve (any node-affecting change, plus every surgical false/throw ⇒ full-rebuild ratchet).

## Execution deviations (R2-07)
- **Applier phase-pin tests were flipped, not "untouched-green".** The plan framed T2/T11/T13 as
behavior-preserving ("every pre-existing applier test untouched-green"). In reality several pre-existing
tests directly encoded the OLD full-rebuild-on-any-topology-change behavior — `Added_equipment_*`,
`Removed_equipment_*`, `Surgical_eligible_tag_delta_mixed_with_added_equipment_rebuilds`,
`Folder_rename_mixed_with_added_equipment_rebuilds`, `Removed_equipment_tags_and_virtual_tags_only_rebuild_*`
— and were flipped to assert the new PureAdd/PureRemove/AddRemoveMix no-rebuild behavior (each doc-commented
"Supersedes the pre-R2-07 … pin"). The genuinely-behavior-preserving tests (surgical attribute path, folder
renames, changed-non-surgical ⇒ rebuild) stayed green untouched.
- **Incidental `RebuildCalled` assertions repointed.** Tests whose *subject* was not the rebuild decision but
which happened to assert `RebuildCalled==true` on a now-PureAdd plan were adjusted:
`AddressSpaceApplierFailureSurfaceTests` (rebuild-failed surfacing) + `OpcUaPublishActorApplyFailureTests`
(apply.failed meter) were repointed to a **rebuild-forcing ChangedEquipment plan** so they still exercise
the SafeRebuild path; `AddressSpaceApplierProvisioningTests` `RebuildCalled` assertions became
`RebuildCalled==false` + `AddedNodes>0` (provisioning still fires on a pure-add).
- **T1 predicate references:** the two eligibility predicates moved to `AddressSpaceChangeClassifier` as
`internal static`; the applier references them directly (`AddressSpaceChangeClassifier.TagDeltaIsSurgicalEligible`)
rather than keeping thin delegating wrappers.
- **Integration + live gates deferred-live (memory constraint).** Per the executor's memory budget
(`*.IntegrationTests` leak ~16 GB/run, other plans running concurrently), the over-the-wire
`SubscriptionSurvivalTests` (add/remove/mixed) were **authored + `dotnet build`-compile-verified but NOT
run**, and T6/T12/T14 docker-dev live-`/run` gates were marked `deferred-live`. These are the F10b
inertness nets and MUST be run in the serial heavy pass before merge/trust.
- **Worktree entry:** `EnterWorktree` refused to switch from the repo root; all work was done against the
worktree via absolute paths + `git -C`, never touching the main checkout.

// every client subscription server-wide survives; coincident surgical tag deltas + folder

// subtree, via the ISurgicalAddressSpaceSink remove members below (each preceded by a terminal
// Bad / RemovedConditionState write so in-flight MonitoredItems observe the removal); subscribers
// of OTHER nodes are untouched. Any false/throw from a remove ⇒ full-rebuild fallback (ratchet).
// • AddRemoveMix ⇒ NO full rebuild. Removes-then-adds within one apply: the removed nodes are torn
// down IN PLACE here (the PureRemove pass), then OpcUaPublishActor's idempotent Materialise passes
// create the added nodes and AnnounceAddedNodes announces them — natural remove-then-recreate
// order even when an id is reused across the remove + add sets (the recreated node is a fresh
// NodeState, correct — it is a different tag). Any remove false/throw ⇒ full-rebuild fallback.
// • Rebuild ⇒ the default-closed safety valve for any node-affecting change (ChangedEquipment /
// ChangedAlarms / non-surgical ChangedEquipmentTags / node-relevant ChangedEquipmentVirtualTags)
// — the classifier's rule 2, which also catches any future plan field that makes a changed
// record unequal, so the worst outcome of a misclassification is today's full rebuild.
