feat(config): Run the fans at full speed by default

FAN_SPEED 30 -> 100. A soak is a thermal test of everything except the
cooling, so the cooling should not be one of the variables in it. At 30%
a long run can throttle partway through, and throttled results read like
a different fault entirely.

Folded into V1.0.11 rather than bumping the version: the tag has not
moved on and this is the same delivery.

+# v1.0.10 — The soak loop stops spinning flat out, and shows you what is still running
+
+## ✨ New features
+
+**Every soak round now reports the background jobs**
+* Script B's monitoring loop prints `bgctl list` (platform jobs) and `jobs` (the login shell's own background jobs) on every pass, right after the platform data. A stress job that dies three hours into an overnight soak now shows up as a shorter list on the next round, instead of only being noticed at the end — or not at all.
+* The two lists answer different questions and are both worth having: `bgctl` knows about the platform's job runner, `jobs` knows about anything the macro backgrounded in that shell.
+
+**A single table for all 144 margin channels**
+* `docs/LTC2980_channel_map.csv` flattens the nine `settings/*.conf` files into one sheet — `Board,CONN,Ch,NetName,Vnom` — so "which board and channel is `PVDD1V5_TSC` on?" is one search instead of opening nine files.
+* `tools/gen_channel_map.sh` regenerates it. **The CSV is output, not source**: edit the `.conf` files and re-run the script, never the other way round.
+* Unused channels stay in the table as `NC` / `-` rather than being dropped, because the channel number is also the PMBus page (`ch / 8` picks the chip, `ch % 8` picks the page) — filtering the gaps out would shift everything after them.
+
+**The bench command lists that these scripts came from**
+* `tools/100G_PRBS.txt`, `tools/TR518.txt` and `tools/fan_ctrl.txt` join the existing `traffic_loopback_*.txt` set: the raw `bcmcmd` / sysfs sequences, kept in the form you can paste into a console when a script is misbehaving and you want to drive the hardware directly.
+
+## 🐛 Bug fixes
+
+**The soak loop ran as fast as the DUT could answer**
+* `while 1` had no pause at all, so each round started the moment the previous one finished. Over a long soak that means constant console traffic and a log full of near-identical samples taken seconds apart. The loop now ends each round with `pause 60`.
+* Note the gap this leaves: the Status sheet asks for a 10-minute sampling interval, and 60 seconds is still hard-coded rather than configurable. This makes the loop sane, it does not finish the job.
+
+**A comment promised a cadence the code never had**
+* The loop was labelled `Get data every 10mins` while running with no delay whatsoever. It now says what it does.

+* **Management connectivity is in use, not preserved.** Both management NICs are up and pinging — drive the run from the serial console.
+* **PRBS is still not wired into the macros.** Run `port_prbs_monitor.sh` by hand if you want it; the calls in A/B/C remain commented out, unchanged from v1.0.9.
+* **TR518 and the loopback traffic test cannot both run.** `tools/TR518.txt` sets `port all lb=mac` and `l2 learn off` across the whole unit, which is the same hardware `blanton_traffic_linespeed` is using. Pick one.
+* **Two settings persist to `config_db.json`** and survive a reboot: LLDP is left disabled and the 100G uplinks are left configured. Restore them before the DUT moves on.

+# v1.0.11 — Saving the margin settings to NVM is now one command, and the command is correct
+
+## ✨ New features
+
+**`margin_save blanton` — all 18 LTC2977 in one go**
+* On this platform the CB FPGA's I2C channels are also exposed as ordinary Linux i2c buses, so every margin controller on the box — CB and both switch boards — can be reached with plain `i2cset`. `margin_save blanton` walks all 18 of them from one flat list: no `margin_init`, no FPGA channel setup, no `pcimem`.
+* The channel-to-bus mapping it relies on (F3 Ch6 → bus 13, Ch7 → 14, Ch8 → 15, Ch9 → 16; CB is bus 4 as before) is now written down in `ARCHITECTURE.md` and the margin README, not just known at the bench.
+* **A partly-populated DUT is a normal build.** Comment out the lines you do not have in `MARGIN_BLANTON_STORE` at the top of `margin.sh` rather than letting the tool talk to boards that are not there.
+* Missing bus and unresponsive chip are reported as two different failures. `/dev/i2c-16 does not exist` means the FPGA's i2c adapters did not enumerate; `i2cset failed (NACK/busy)` means the board is absent or the address is wrong. Chasing the second when you have the first wastes an afternoon.
+
+**`margin_save all` — every board in `settings/`**
+* Runs `margin_init` + `margin_save` across all nine boards, then puts back whichever board you had loaded, so a following `margin_status` still reports the board you were looking at.
+* It does not stop at the first failure: a half-saved set is harder to reason about than a fully-attempted one. The summary names the boards that failed.
+
+Both print a per-chip line and a `N saved, M failed` tally, and both return a non-zero exit code when anything failed.
+
+**The fans now default to full speed**
+* `FAN_SPEED` in `config.ttl` is 100 instead of 30. A soak is a thermal test of everything *except* the cooling, so the cooling should not be a variable in it — and a DUT that throttles halfway through a run produces results that look like a different fault. Lower it deliberately if quiet operation is what you are measuring.
+
+## 🐛 Bug fixes
+
+**A failed NVM write still reported success**
+* `margin_save` discarded the result of every write, so a NACK printed `Change Saved` exactly like a successful store. For the one operation in this tool that is permanent, that is the worst place to stay quiet. Each store is now checked and named if it fails.
+
+**`STORE_USER_ALL` was sent with a data byte it should not have**
+* The command went out as `0x15` followed by a dummy `0x00` — an SMBus write-byte, where `STORE_USER_ALL` is a send-byte. The LTC2977 tolerated it, but tolerance is not correctness. It is now `i2cset ... 0x15 c` on the native path and a no-data `cb_pmbus_write` on the FPGA path.

+
+## ⚠️ Before you run
+
+* **`margin_save` in any form writes NVM permanently.** A power cycle does not undo it. `margin_save all` and `margin_save blanton` do it to all 18 controllers at once. Run `margin_status_all.sh` first and never call any of them during a test run — the macros do not, and should not be made to.
+* **The 18 raw commands were verified on the DUT; the wrapper was not.** `margin_save blanton` issues exactly the sequence that was run by hand at the bench, and the packaging was tested against stubbed hardware, but the function itself has not been run on a DUT yet. Watch the per-chip lines the first time.
+* **Declare the switch population.** `SWB_UNIT0` / `SWB_UNIT1` in `config.ttl` say which switch units this DUT has; traffic and the readiness gate both follow them.
+* **`FAN_SPEED` is now 100.** It is applied at the start of every run, so this build runs the fans flat out unless you change `config.ttl`. Expect the noise.
+* **Management connectivity is in use, not preserved.** Both management NICs are up and pinging — drive the run from the serial console.
+* **PRBS is still not wired into the macros.** Run `port_prbs_monitor.sh` by hand if you want it; the calls in A/B/C remain commented out.

+
+**只寫其中幾顆**才需要 `script/margin_save_all.sh`，編 script 頂端的 `BOARDS` 陣列：
+
 ```bash
 source script/margin_save_all.sh
 ```
 
-要改寫哪幾顆，編 script 頂端的 `BOARDS` 陣列即可（同前述）。
+### 送出去的是什麼
+
+`margin_save` 對每顆 LTC2977 送一次 `STORE_USER_ALL`（PMBus command `0x15`），
+**不分 page**（這是整顆晶片的命令），也**不帶 data byte** —— 它是 SMBus send-byte：
+
+```bash
+i2cset -y 4 0x5C 0x15 c            # CB CONN13（原生 bus 4）
+cb_pmbus_write 8 0x5C 0x15         # SWB0 CONN13（CB FPGA F3 Ch8）
+```
+
+> v2.7.0 之前送的是 `0x15 0x00`（write-byte）。LTC2977 在 CB 上吃得下去，但那是零件寬容，
+> 不是規範。同時 v2.7.0 起會檢查回傳值 —— 以前 NACK 了還是印 `Change Saved`。
+
+每顆之間會 `sleep $MARGIN_STORE_SETTLE`（預設 0.5 秒）。這不是量測值，是保守的保護：
+NVM 寫入需要時間，而這支工具**沒有**去 poll 零件的 busy bit。`margin_save all` 連續送 18 次，
+這個間隔就是唯一的緩衝。要關掉設成空字串即可。
+
+## `margin_save blanton` — Blanton SONiC 專用
+
+Blanton 這台把 CB FPGA F3 的 I2C 通道**同時掛成了原生 Linux i2c adapter**，
+所以 SWB 上的 LTC2977 不必走 `cb_pmbus_*` / pcimem，用 `i2cset` 直接打得到：
+
+| FPGA F3 通道 | Linux bus | 板 / 接頭 |
+|---|---|---|
+| Ch6 | 13 | SWB0 CONN14 / CONN16 |
+| Ch8 | 15 | SWB0 CONN13 / CONN15 |
+| Ch7 | 14 | SWB1 CONN14 / CONN16 |
+| Ch9 | 16 | SWB1 CONN13 / CONN15 |
+| —（原生） | 4 | CB CONN13 |
+
+因此 `margin_save blanton` 就是一張平表跑完 18 顆，**不需要 `margin_init`**、
+不做 FPGA 通道初始化、不做 probe，也不會動到你當前載入的那顆板子：
+
+```bash
+margin_save blanton
+```
+
+```
+  CB   CONN13  bus 4  0x5C : saved
+  SWB0 CONN13  bus 15 0x5C : saved
+  ...
+margin_save blanton: 18 saved, 0 failed
+```
+
+送出去的就是這 18 行（2026-08-27 上機驗證）：
+
+```bash
+i2cset -f -y 4  0x5C 0x15   ;  i2cset -f -y 4  0x5E 0x15    # CB   CONN13
+i2cset -f -y 15 0x5C 0x15   ;  i2cset -f -y 15 0x5E 0x15    # SWB0 CONN13

+i2cset -f -y 14 0x62 0x15   ;  i2cset -f -y 14 0x64 0x15    # SWB1 CONN16
+```
+
+`-f` 是因為這些 bus 上的 LTC2977 可能已被 kernel driver 認走；上機驗證過的指令帶 `-f`，就照原樣保留。
+
+**這台沒裝滿的話**，把 `margin.sh` 頂端 `MARGIN_BLANTON_STORE` 陣列裡對應的行註解掉即可，
+不要讓它去打不存在的板子。bus 節點不存在（`/dev/i2c-N` 沒有）與晶片不回應（NACK）
+會分別報不同訊息 —— 前者代表 FPGA 的 i2c adapter 根本沒 enumerate，後者才是板子的問題。
