The Wi-Fi, LoRa first-stage and Partition Expander bridges serve an
unauthenticated /update behind an AP whose password was fixed and published,
so anyone in range during a migration could upload firmware while the private
key is staged. Use the old node's saved admin password as the WPA2
passphrase, read from /com_prefs or /node_prefs at offset 56 as the firmware
loads it. The operator already used that password to start the old updater.
Fall back to the published password, with a serial warning, when the saved
admin password is missing, unreadable, shorter than 8 characters or not
printable ASCII, so no node becomes unreachable. The legacy filesystem is
mounted without formatting and the password is never printed. Migration
admission, flash sequencing, /update gating and the USB bridge are unchanged.
Update both guides and the package README.
Add a sanitizer-backed host test that compiles the bridge's actual Wi-Fi
block against fake SPIFFS and WiFi: both boots, file precedence, WPA2 length
and terminator bounds, printable characters, stock 1.10/1.11 file sizes,
truncated fields, and mount, seek and partial-read failures. It fails 8 of 8
on the previous code and catches 27 of 27 code mutations. Verified 13 related
host test files and the esp32_s3_4mb_partition_migrator build.

On a room server the guest password grants Read/Write, which the login
replay store treats as a role that needs a durable record. Every new
guest-password identity therefore took one of the 128 permanent slots,
and once they were used up the store failed closed for every new
identity, including a new administrator device, until the filesystem was
erased. Rooms often publish the guest password.
A guest-password Read/Write session (one without explicitly assigned
permissions) now uses the policy public readers already use: it must
beat its in-boot timestamp and any record the identity already has,
which is still advanced, but it never creates a new record.
Administrator logins and explicitly assigned roles keep the durable
reservation and still fail closed on a full store.
Tests: test_room_login_replay_capacity.py runs the real room login
handler against the real ClientACL replay store with ASan/UBSan: guest
churn cannot lock out a new admin or assigned writer, a former admin's
record still binds guest-password logins, and a store full of privileged
records still refuses a new admin. It fails 2 of 3 on the previous code.
Two expectations in test_room_login_integration.py and the login profile
contract follow the new policy.

Require a real raw-table save for same-value channel SETs. This repairs the false acknowledgement after successful constructor recovery of an older backup followed by a failed candidate write.
Keep resolved alias keys, raw AUTO policy and runtime generation untouched. Preserve GET and unchanged contact behavior, changed-policy validation and indeterminate-publication quarantine.
Cover real stale-backup creation, failure/retry, reboot and exact old-skip controls. Add actual alias/BaseChatMesh and raw app-key regression tests on all four backends. Verified 117 related host tests, 16 final caller rechecks, four firmware qualifications and linked nRF52 crypto checks.
Latch only channel storage on Indeterminate writer outcomes, including failed transaction setup. Preserve ordinary failure retries, confirmed rollback, contacts and the live accepted channel keys.
Exercise actual CLI and binary callers with all four storage backends, reboot behavior and exact missing-latch negative controls. Share TX storage failure diagnostics to retain the strict Wio-E5 Mini flash gate.
Verified 103 related host tests, four platform firmware qualifications and linked nRF52 crypto/stack checks. A separate stale-backup constructor/no-op acknowledgement case remains under audit.
Release cached path snapshots before resetting contacts while retaining the requesting transport and table revision for a complete stream restart. Keep explicit session cancellation unchanged and avoid copying uncached contact buffers.
Cover cached and uncached recovery, transport isolation, empty reloads, backpressure, and the former cancellation as a negative control.
Recheck cached immutable paths before resetting the live table after raw I/O failure. Keep accepted RAM mutations, current jobs and save deadlines when reads recover; stronger source or publication uncertainty still forces full recovery. Use the existing recovery byte and a fixed scratch buffer, with no cache allocation or eviction.
Cover full-cache transient recovery, persistent I/O and checksum failures, nRF unread-scope restoration, active ESP jobs, real uncertain publication and unchanged lazy deadlines with sanitizer tests and restored-reset negative controls.
Do not classify legacy or page-name stat errors as unread payloads. Keep candidate contact files unchanged, retry source selection, and use bounded volatile operation if authority remains unknown. Cover legacy absence, downgrade leftovers, cleanup-time metadata recovery and persistent faults with actual-source sanitizer tests and restored-bug negative controls.
Verify fallback namespace moves before accepting publication or rollback. Reload readable contact images at a safe host boundary, discard only unreadable contact data after bounded retries, and permit volatile operation when storage cannot recover. Preserve unrelated stores and fail explicit durability requests truthfully.
Keep existing flash, RAM, OTA and capability limits by streaming nRF52 preferences through the validated wire table and sharing identical contact deadline resets. Add fault-injection, sanitizer, legacy-image parity and CLI lifecycle regressions.
Verify public images after every rename attempt, expose publication outcomes, and use an independent CRC32C fingerprint so valid IEEE-CRC-tailed images cannot mask a stale target. Preserve persistent formats and reject directories for empty images.
Reconcile uncertain migration journals before choosing filesystem authority. Preserve retained contact snapshots when page publication is unconfirmed without clearing dirty state or acknowledging the new page generation.
Add readback, rename, CRC-tail, migration reboot/quarantine, and snapshot eviction regressions. Keep complete RAK Full Companion within the unchanged OTA ceiling through equivalent code compaction, with no feature or validation cuts.
Run DHCP and renewal in a cooperative worker, bound socket commands, and retain SPI ownership until cleanup is safe. Preserve framing deadlines, response ownership and whole-frame replay, including pending-ACK queue pinning.
Budget the worker additively and retain all OTA names with an exact-checked Full-only compact index. Add full-driver, sanitizer, queue, shutdown, storage and memory regression coverage.
Let the mesh timed OTA retry guard own byte-identical requests instead of the permanent bridge FIFO. Bind bridge ingress to its primary profile generation and preserve UART reflection/liveness protections. Verified a LoRa to ESP-NOW to LoRa update with outage recovery and install.
Delay automatic GPS-free NodeInfo until a quiet TX gap, invalidate stale metadata after durable node renames, and refresh the profile when same-tuple publication releases its busy guard. Cover the real Companion methods and document the behavior.
