+address — a disabled counter reads a constant `0` (a *vacant* macro reads `BadNoData`, never `0`; see
+[Wire decode corrections](#wire-decode-corrections-2026-10)). A `0` from `MACRO:3901` is therefore a valid
+decode of "counter not counting", not a driver fault. Cycle time per part is not provided as a node — see the
+[virtual-tag recipe](#recipe-cycle-time-per-part-virtual-tag-272).
+
+### Recipe: feed / rapid / spindle override via PMC (#259)
+
+The CNC's override values are ordinary PMC signals (the MTB ladder copies the operator-panel switches into the
+G area), so they are readable today with plain PMC tags — read-only, no new driver surface. On the standard
+FANUC signal map:
+
+| Signal | PMC address | Notes |
+|---|---|---|
+| Feed override `*FV0-*FV7` | `G12` (Byte) | **Inverted**: the byte holds the one's complement. Percent = `255 - value` for a binary-coded switch (`255` = 0%, `155` = 100%); gray-coded/ladder-converted panels differ |
+| Rapid override `ROV1`, `ROV2` | `G14.0`, `G14.1` (Bit) | Two bits select 100% / 50% / 25% / F0 |
+| Spindle override `SOV0-SOV7` | `G30` (Byte) | Percent, usually a direct 0-150 value |
+
+Author them as normal PMC tags (`G12`, `G14.0`, `G30` — G is accepted on the 30i family and the 16i). To publish a
+percentage rather than the raw byte, derive it with a virtual tag (`255 - ctx.GetTag("{{equip}}/FeedOverrideRaw")`).
+
+⚠️ **The addresses above are the FANUC *standard* signal assignment; the meaning is defined by the machine
+builder's ladder.** Confirm each against the machine's own PMC signal list before trusting the number, and
+validate with the panel switches at known positions (read-only observation — never write PMC). **Modal G/M/T
+codes are not available**: `cnc_modal` has no known wire command id here (see
+[Not ported](#not-ported-633-backlog)).
+
+### Recipe: cycle time per part (virtual tag, #272)
+
+A per-part cycle time is **not** a driver feature: `FIXED:Timers/CycleSeconds` and the parts count
+(`MACRO:3901` / `PARAM:6711`) are both already readable, and the result is a pure function of them. Author the
+count as an equipment tag named `PartsCount` and `FIXED:Timers/CycleSeconds` as `CycleSeconds`, then add a
+virtual tag (Double, change-triggered by those two references):
+
+```csharp
+// Average cycle seconds per part since the counters were last cleared.
+var parts = (double)ctx.GetTag("{{equip}}/PartsCount").Value;
+var cycle = (double)ctx.GetTag("{{equip}}/CycleSeconds").Value;
+return parts > 0 ? cycle / parts : null;   // no parts yet: no average
+```
+
+This is a **running average**, valid only while both counters accumulate from the same reset (an operator clearing
+one but not the other skews it until they are cleared together). The exact *last-cycle delta* (difference
+`CycleSeconds` across a parts-count step) needs the script to remember the previous sample, and virtual-tag scripts
+have no documented persistent state (see [`docs/ScriptEditor.md`](../ScriptEditor.md)) — compute that in the
+consuming system (e.g. ScadaBridge) from the two raw tags instead. Both inputs hold while either is Bad, per the
+quality contract.

+
+The #607 porting backlog (#257-#272) was triaged against this read-only driver. Disposition:

+**Done / documented:** #257 `Status/` fixed subtree, #258 parts count ([`MACRO:3901`](#parts-count-macro3901-or-param6711)),

+(`WireFocasClient.WriteAsync` returns `BadNotWritable`) and that is a safety decision for real CNCs, not a
+gap: no write infrastructure / per-tag opt-in (#268), no `cnc_wrmacro` / `cnc_wrparam` (#269), no `pmc_wrpmcrng`
+or PMC bit read-modify-write (#270), no password / unlock parameter (#271). Nothing in the driver or CLI should be
+read as a path toward them.
+
+**Blocked — need an authoritative wire capture first.** None of the following has a wire command id known to this
+repo or to the sister ignitionoee client, and neither mock serves them over the binary wire:
+
+| Item | Capability | Blocked by |
+|---|---|---|
+| #259 (modal part) | Modal G / M / T codes (`cnc_modal`) | no wire id |
+| #260 | Tool number / tool life, work-coordinate and tool offsets (`cnc_rdtofs` / `rdzofs`) | no wire ids |
+| #261 | Operator messages (`cnc_rdopmsg`) and the currently-executing block text (`cnc_rdexecprog`) | no wire ids |
+| #263 | `DIAG:` address area (`cnc_diagnoss`) — the highest-value one: a single generic area would unlock many fields | no wire id |
+| #264 | Multi-path / multi-channel (`cnc_getpath`) — the wire layer has `PathId` plumbing but no per-device/tag option | no wire id, and no multi-path control to validate against (the Makino is single-path) |
+| #267 | Alarm history (`cnc_rdalmhistry`) | no wire id; the live alarm surface ([#647](#alarm-projection)) comes first |
+
+⚠️ **Do not discover these ids by probing the production Makino.** An unknown or guessed command id could map to a
+function that is not a read, and even known ids misbehave on the 31i-B (`cnc_rdparam` 0x000E answers `EW_FUNC`). The
+0x00D3 `cnc_getfigure` lesson (see Wire decode corrections) already showed that an id agreed between two mocks can be
+fiction. The prerequisite is an authoritative capture: real FWLIB on a Windows host against a **non-production**
+control, or a passive capture of an existing FWLIB application's traffic.
