phase: 03_session_takeover
**Phase 03 `session_takeover` — final verification pass. All green.**
All four task files were already in `.agents/phases/complete/03_session_takeover/` with per-task reports, so this was the phase-level close, not new implementation.
**Completion criteria**
1. *2nd controller authenticates + takes the bridge; a 3rd is refused* — met host-side: `test_claim` 102 (whitelist matrix, `acceptsUpgrade` one-claim-at-a-time, both deadline clocks across `millis()` rollover, 64-byte cap through the real codec), `test_relayctl` 308 (`--take-over` = `T`,`X`,`H`; default refusal names the flag and sends no `X`), `test_page` 142 (claim→button→one click→`T` then `X` only). Refusal mechanism stated precisely: a second claim gets `503`/`E3`, a third *socket* gets the slot refusal (`slotrefused`).
2. *Handover releases then adopts, lands disarmed* — pinned: `closeLink("taken over")` before adoption (inverting it fails exactly 1 check, reverted); no `arm`/`setArmed`/`armed = true` in the `X` path (inserting one fails exactly 1 check, reverted); un-authenticated `X` admitted in `claim.h` fails `test_claim`+`test_relayctl` (reverted). Also verified by reading: `serveClaim` never writes `_lastInboundMs`/`_controllerSeen`, so a parked claim cannot hold the board armed past 8 s.
3. *Incumbent page says taken over, disarmed, no auto-reclaim* — `onE12()` + `test_page` (disarms, releases mouse, ends typing run, pill `taken over`, reconnect loop off).
4. *Three source pins fail on inversion* — re-demonstrated in this pass, all reverted (`src/claim.h`, `src/control_server.cpp` byte-identical to pre-inversion).
5. *Gate green + README/AGENTS say takeover cannot arm* — yes.
**Validation** — `bash .agents/validate.sh` → **exit 0**: 12 suites **5026 checks, 0 failures** (normal and `SANITIZE=1`), `bridge`/`console`/`rollback` all SUCCESS, page bytes 59 286, README/AGENTS claims OK, hygiene OK. Extra lint: `ruff --select F,E9` clean, `bash -n` clean, `py_compile` clean. Coverage on new/changed logic: `claim.h` 100 % (11 lines), `status.h` 100 % (29), `proto.h` 94.8 % (229), relayctl take-over lines 14/15 (the miss is a `def` continuation trace never records).
**Defects fixed (docs only — no code defect found)**: bug 6 claimed a 2nd `/ws` upgrade "is still refused"; Measured-behaviour samples lacked `taken=`/`busy`/`tkov`; footprint + TLS-cost rows quoted phase-02 numbers while claiming to be what the gate prints (now 99 744/1 257 933, 67 352/1 178 173, 93 568/1 157 609 → TLS = +6 176 B RAM/+100 324 B flash); page-delivery/handshake rows dated; `AGENTS.md` pure-module list was missing `claim.h`.
**Hardware**: no device run. The board still runs pre-phase-03 firmware, reflash/arming mutates a live device (the target is this machine), and both controllers need the operator's passphrase — guessing feeds the shared 5-fail lockout. The 3 blank rows (third-controller refusal, chord labels, nothing-outlives-the-link) are now recorded `skipped (no device run)` with the exact closing commands in `.agents/HW_VERIFICATION.md`.
**Tree left for the harness**: index untouched (0 staged), no history changes; `todo/03_session_takeover/00_phase.md` moved to `complete/` (matches the phase-02 rename pattern); untracked files the commit must include: `.agents/validate.sh`, `src/claim.h`, `tests/test_claim.cpp`, `.agents/phases/complete/03_session_takeover/`, `.agents/reports/03_session_takeover/`. Next phase: `todo/04_controller_page_responsive/`.
