       "description": "**Goal:** Document the native transport, the switch, the known gaps and the client-visible type-check change, in the repo and in the umbrella history.\n\n**Files:**\n- Modify: `docs/drivers/AbCip.md` (sections: \"Transport (`Transport` option)\", \"Native transport behaviour\" covering connection sharing, MSP packing, the type check and press-safety limits, and \"Known gaps\" covering simulator-only writes, PLC-5/Micro800/routed paths, and libplctag deletion blocked on a bench controller)\n- Modify: `docs/drivers/AbLegacy.md` (Transport section, PCCC simulator-only gap, PLC-5 status from Task 8, ST byte-order status from Task 14)\n- Modify: `docs/drivers/AbServer-Test-Fixture.md` and `docs/drivers/AbLegacy-Test-Fixture.md` (suites now run per transport; the capture recipe `scripts/ab-capture/capture.sh`)\n- Modify: `CLAUDE.md` (one short paragraph under a new heading \"AB drivers: native transport (`Transport`)\" with the switch, the confinement guard, and a pointer to the docs; keep it short, under 15 lines)\n- Modify: `../scadaproj/.claude/skills/sister-project-history/otopcua.md` (append a dated entry), on scadaproj's `main` per the CLAUDE.md procedure\n\n**Acceptance Criteria:**\n- [ ] `docs/drivers/AbCip.md` states explicitly:\n  - The native path reports `BadTypeMismatch` for a same-width mis-authored type that libplctag reads as Good garbage, with an example (DINT authored, REAL returned).\n  - That is the fix working, and it is called out as client-visible.\n- [ ] Every config key added (`transport`) is documented with its values, its default and string serialization.\n- [ ] The scadaproj history entry is committed on `main` and pushed. The OtOpcUa index **row** in `../scadaproj/CLAUDE.md` is **not** touched; the summary does not change, since the driver set and wire contract are the same.\n- [ ] The scadaproj branch is restored afterwards.\n\n**Verify:** `grep -n \"Transport\" docs/drivers/AbCip.md docs/drivers/AbLegacy.md CLAUDE.md` shows the new sections; `cd ../scadaproj && git log origin/main -1 --format=%s` shows the history commit.\n\nSteps + code: docs/plans/2026-10-07-native-ab-transport.md \u00a7 Task 20.\n\n```json:metadata\n{\"files\": [\"../scadaproj/.claude/skills/sister-project-history/otopcua.md\", \"CLAUDE.md\", \"docs/drivers/AbCip.md\", \"docs/drivers/AbLegacy-Test-Fixture.md\", \"docs/drivers/AbLegacy.md\", \"docs/drivers/AbServer-Test-Fixture.md\", \"scripts/ab-capture/capture.sh\"], \"verifyCommand\": \"grep -n \\\"Transport\\\" docs/drivers/AbCip.md docs/drivers/AbLegacy.md CLAUDE.md\", \"modelTier\": \"standard\", \"model\": \"sonnet\", \"acceptanceCriteriaCount\": 4}\n```",
