docs: Record V1.2.3 in Script A's history and add the release note

Script A: header to V1.2.3 / 2026-09-23; five entries under V1.2.3 for
setup_pmon.ttl, ddr5_temp.sh, hsc_temp_readback.sh, avt_pmpower.sh and
Script 4, with notes on the ~4 s per snapshot, the exec bit, the CRLF in
hsc_temp_readback.sh v1.0.0 and AVT not being shipped.

CLAUDE.md: status to V1.2.3; the PMON temperatures and Script 4's CPU
power in the overview; a commands block for the three new scripts; fix
the stale Script 5 file name and the "last release V1.1.5" line.

ARCHITECTURE.md: Script A ref to V1.2.3; the three scripts in the tree
and in setup_pmon's comment; avt_pmpower.sh in Script 4's row; the git
tag checkbox to V1.2.3.

+# v1.2.3 — DIMM and hot-swap temperatures in every snapshot, and CPU power next to the switch rails
+
+## ✨ New features
+
+**Every PMON snapshot now reads DDR5 DIMM and hot-swap controller temperatures**
+* `utils/setup_pmon.ttl` runs `ddr5_temp.sh` and `hsc_temp_readback.sh` right after `show platform temperature`. Because `setup_pmon` is shared, this lands everywhere a snapshot is taken: Script A's baseline, each Script B soak round, Script C, the Script 4 loop and every Script 5 check point.
+* `ddr5_temp.sh` reads the SPD5118 hub on each DIMM: i2c bus 5, `0x50` / `0x51`, register `0x31` (`bit[12:2]`, sign bit 12, 0.25 °C/LSB). A read that fails prints `read fail` — never a number it did not read. Bus and addresses can be passed: `ddr5_temp.sh [bus] [addr ...]`.
+* `hsc_temp_readback.sh` reads both LTC4287 hot-swap controllers on i2c bus 28 — `HSC_MAIN @ 0x40` (PU11 internal / PQ1 external) and `HSC_STBY @ 0x45` (PU46 internal / PQ53 external). The source is selected through `0xF3`, then `READ_TEMPERATURE` `0x8D` is read in Kelvin and converted.
+
+**Script 4 logs AMD CPU package power every round**
+* `avt_pmpower.sh` runs `AVTCMD -module pmm "get_pmdata()"` and summarizes `SktPwr`, `PPT Fast` / `PPT Slow` against their limits, and `MemPwr`.
+* It runs after the two `TH6_SWB` power readbacks, so each sample now puts the switch rails and the CPU package side by side.
+* `-q` prints the summary only. Exit `2` = AVTCMD not found, `3` = AVTCMD failed, `4` = the PM table parsed to nothing (format changed).
+
+## 🐛 Bug fixes
+
+**`hsc_temp_readback.sh` was saved with CRLF line endings**
+* Copied to the DUT as-is, bash on SONiC fails on the first line (`$'\r': command not found`). The shipped file is LF.
+* Its comments said the delay between I2C transactions was 100 ms; `DELAY=0.5` is what actually runs. Comments corrected and a Version History header added.
+
+## 📦 Downloads
+
+| File | Contents |
+|---|---|

+```bash
+chmod +x ~/Blanton_Script/*.sh
+grep -rlU $'\r' ~/Blanton_Script              # expect no output
+ls ~/AVT_Linux_NDA_2.8.37/AVTCMD              # Script 4 only - must already be there
+```
+
+## ⚠️ Before you run
+
+* **Redeploy `Blanton_Script/`.** If an earlier copy of `hsc_temp_readback.sh` reached the DUT, it is CRLF and will not run.
+* **`chmod +x` after deploying.** `setup_pmon` calls both new scripts by path. Without the exec bit each call is `Permission denied` and the snapshot carries on without those rows — nothing stops, nothing warns.
+* **Each PMON snapshot is ~4 s longer.** `hsc_temp_readback.sh` sleeps 0.5 s twice for each of its four readings. It adds up in Script 5, which snapshots at every check point.
+* **AVT is not in this package (NDA).** Unpack it on the DUT at exactly `~/AVT_Linux_NDA_2.8.37/` before Script 4. Missing, the call exits `2` every round and the loop runs on without a CPU power reading.
+* **Script 4 logs the full PM table once a minute**, because the call is made without `-q`.
+* **CPU power is SMU telemetry, not a measurement.** Its absolute accuracy is whatever the BIOS SVI calibration gives — cross-check against the VR's PMBus `READ_POUT` when the number matters.
+* **None of the three new scripts has been checked against the Script A/B/C flow on hardware yet.**
+* **Do not run the boot cycle with `EN_Cold_Warm_boot = 0`**, and check the hard-coded BDF on every board before the cold path (see v1.2.2).
+* **BER, the DSC cycle, `blanton_traffic_linespeed` and `blanton_tr518.sh` cannot overlap.** They all take the same ports.
+* **Script 4 has no teardown**: finish it with `blanton_tr518.sh stop` **and** `systemctl stop mlucas-amm`.
+* **`blanton_multiphase_margin.sh save` is permanent**, and must not be mixed with `margin.sh`.
+* **`FAN_SPEED` is 100.**
