-feat: evidence-based non-extrusion detection — recognize header-less real CNC/laser files (#189)
-
-The phase-3 CNC/laser detectors were tuned on synthetic fixtures and matched **none** of the real
-public samples (LaserGRBL, LinuxCNC, GRBL CAM output) — real controller output usually has **no
-generator header** and writes commands **mid-line** and **concatenated** (`s3400 m3`, `g1z-.1`).
-
-Detection is now **evidence-scored**, not banner-only:
-
-- A shared `scoreEvidence` extractor strips comments (so `(M3)` / `; LinuxCNC` in a comment can't
-  create a false marker) and matches commands as words anywhere on a line.
-- **GRBL laser** — LightBurn / `$32=1`, **or** the header-less form: a tool-on command (`M3`/`M4`) with
-  `S` power and **no Z-plunge** (lasers are planar).
-- **GRBL / generic mill** — `M3` spindle that **plunges into negative Z** with no extrusion (a milling
-  fingerprint that separates it from a planar laser); banner optional.
-- **LinuxCNC** — explicit header, **or** RS274NGC **O-word** subroutines/flow (`o100 sub`).
-- Extrusion detection tightened to `E` on a **motion line**, so LinuxCNC `M67 E0 Q…` analog laser power
-  is no longer mistaken for FDM.
-
-Real-file result: **0/6 → 3/6 detected, each with the correct machine class** (laser→laser, mill→mill,
-LinuxCNC→linuxcnc); the misses are honest — files with a commented-out or absent spindle carry no
-tool-state to infer. Still **experimental tier** (claims reported `inferred`) — detection working on
-real files is one input; semantic ground truth (does our `Cut` = actual cutting, `S` scale) still wants
-a real machine or a trusted reference.

-feat: canned drilling cycle expansion — G81/G82/G83 (DD-012 phase 2, #189)
-
-CNC canned drilling cycles previously produced **zero geometry** — holes vanished. They now expand to
-explicit sub-moves so the drilling is real, classified toolpath:
-
-- **G81/G82** (drill / drill-with-dwell): rapid to the hole XY, rapid down to the R plane, **feed to
-  depth (`Cut`)**, rapid retract.
-- **G83** (peck): the plunge is a peck loop — feed down by `Q`, rapid-retract to R between pecks, until
-  reaching depth; each down-feed is a `Cut`.
-- **G98/G99** set the retract plane (initial Z vs R); **G80** cancels; a `G0`–`G3` motion also cancels.
-- **Modal repeat**: with a cycle active, a bare `X`/`Y` line drills another hole (retaining Z/R/Q and
-  the initial plane) — the common CNC hole-pattern form.
-- Rapids are `Travel`, plunges are `Cut`; new capability **`cannedCycles`** (`known` once a cycle is
-  seen, else `unavailable`).
-
-FDM output is unchanged (no canned cycles in FDM); the native-golden corpus gains only the additive
-`cannedCycles` capability, with no geometry change.

-feat: non-extrusion color modes — color-by-power + cut-vs-rapid (DD-012 phase 4, #189)
-
-Two new `ColorMode`s consuming the #189 channels (DD-012 D7):
-
-- **`power`** — ramps each segment's modal `toolPower` (laser power / spindle RPM, the `S` value) onto
-  a color ramp, the CNC/laser counterpart to color-by-speed. Auto-ranged (`toolPowerRange`) or explicit;
-  `NaN` (tool off) or a file parsed without the `toolPower` channel → fallback, never a fabricated color.
-  Capability-gated on `toolPower` (the Three renderer's `isColorModeAvailable` gates it).
-- **`moveKind`** — cut-vs-rapid: productive moves (`Extrude` or `Cut`) vs rapids (`Travel`) — the
-  "where the tool is actually working" view. Reads the always-present `kind` channel, so it is always
-  available.
-
-Both flow through `createSegmentColorer`, so the Three and Canvas-2D renderers get them for free. FDM
-coloring is unchanged.

-feat: non-extrusion dialect families + validation tiers (DD-012 phase 3, #189)
-
-Adds controller detection and the **validation-tier honesty mechanism** for CNC/laser toolpaths:
-
-- New dialects (`@chestnutlabs/gcode-dialects`): **GRBL laser** (LightBurn / `$32` laser mode / `M4`+`S`),
-  **GRBL mill** and **LinuxCNC** (`M3` spindle, `%`/banner envelopes). Registered in the batteries worker.
-- Each dialect adds provenance (`cnc.controller`, `cnc.machineClass`, `cnc.toolPowerLabel`) and a
-  **validation tier** (`cnc.validationTier`). Per DD-012 D6: an **experimental** dialect reports its
-  non-extrusion claims (`cutMoves` / `toolPower` / `cannedCycles`) as **`inferred`** (never `known`),
-  with a `cnc-dialect-experimental` disclosure — and only for claims the file actually made (an unused
-  feature is never fabricated).
-- **All launch dialects ship `experimental`** (synthetic fixtures only). A single `tier: 'validated'`
-  flip per controller promotes its claims to `known` once confirmed on real hardware (DD-012 §8/§15).
-
-Geometry is untouched (dialects only annotate/label). FDM detection is unaffected — CNC dialects do
-not match FDM output.

-feat: non-extrusion `Cut` move classification + tool-state modal (DD-012 phase 1, #189)
-
-Non-extrusion toolpaths (CNC / laser / plotter) no longer collapse their productive moves into
-`Travel`. The parser now tracks a tool-engaged modal state — `M3`/`M4` (spindle/laser on, incl. the
-`M03`/`M04` leading-zero form) engage it, `M5` disengages — and classifies a move with **no extrusion
-`E`** while the tool is engaged as the new **`MoveKind.Cut`** bit (a CNC/laser/plotter counterpart to
-`Extrude`, composing with `ArcSegment` like the other kinds).
-
-- New IR move kind `MoveKind.Cut = 1 << 7` (`@chestnutlabs/toolpath-core`).
-- New capability **`cutMoves`**: `known` once a tool-state modal is seen (a CNC/laser/plotter file),
-  `unavailable` for FDM.
-- **FDM is byte-identical**: FDM slices never issue `M3`/`M4`, so `Cut` is never set and every move
-  stays `Extrude`/`Travel` exactly as before (verified against the native-golden corpus; the CNC
-  fixtures `demo-easel`/`demo-mach3` are documented intentional adapter-divergences).
-
-Modal tool-state *value* channels (laser power / spindle RPM via `S`), canned-cycle expansion, and
-dialect families follow in later DD-012 phases.

-feat: modal motion continuation — bare coordinate lines repeat the last G0–G3 (DD-012 phase 2, #189)
-
-CNC/LinuxCNC-style G-code frequently omits the `G` word on repeated moves (`G1 X0 Y0` then bare
-`X10 Y0` / `X20 Y0`). The parser previously **dropped** those lines entirely — a three-move path
-produced a single segment. It now tracks the active `G0`–`G3` motion mode and treats a line whose
-leading word is a coordinate axis (`X`/`Y`/`Z`, with no `G`/`M`/`T` command) as a continuation of
-that mode, so the full toolpath is emitted and classified/colored consistently (incl. inline `S`
-for `toolPower`).
-
-FDM output is **byte-identical** — slicers always emit the `G` word, so the continuation path never
-triggers (the native-golden corpus is unchanged). This unblocks canned-cycle repeat (next phase).

-
-Adds the shared, opt-in **`ModalChannel`** mechanism DD-012 D3 is built around, and its first channel:
-**`toolPower`** — the modal spindle/laser `S` value while a tool is engaged.
-
-- `ParseOptions.modalChannels?: readonly string[]` — request per-segment modal channels by id.
-  Supported id: `'toolPower'`. Unknown ids are ignored with a `modal-channel-unsupported` warning.
-- `ToolpathSegments.modal?: Readonly<Record<string, Float32Array>>` — one Float32 column per requested
-  channel, present **only** when requested. An unset value is `NaN` (an honest "no value here"), never
-  a fabricated `0`. `toolPower` is the modal `S` (set on `M3`/`M4` and inline on GRBL-laser motion
-  lines) while engaged, `NaN` when the tool is off (`M5`).
-- New capability **`toolPower`**: surfaced only when the channel is requested — `known` once a
-  tool-state modal is seen, else `unavailable`.
-- **Default parse pays nothing**: no `modalChannels` ⇒ no `modal` on the IR, no extra columns, FDM
-  output unchanged. The budget-aware SoA writer (DD-003) grows the opt-in columns in lockstep and
-  accounts their bytes.
-
-Presentation (Watts vs RPM) is a dialect label, not a separate channel (DD-012 D4); #180's
-fan/temp/accel color channels reuse this same mechanism in a later phase.

-fix: G0 rapids classify as Travel, not Cut, even while the tool is engaged (#189)
-
-The non-extrusion `Cut`/`Travel` classifier keyed only on tool-state (`M3`/`M4` latched), so on a
-router — where the spindle stays on across rapids — every `G0` reposition was counted as a cutting
-move. DD-012 D2 §4.2 already specifies that rapids stay `Travel`; this brings the implementation in
-line: only a **feed** move (`G1`/`G2`/`G3`) with the tool engaged and no `E` delta is `Cut`; a `G0`
-rapid is `Travel` regardless of tool state (a GRBL-laser also gates the beam off during `G0`).
-
-Surfaced by the CNC/laser validation harness on real files — e.g. the `easel` router fixture went
-from 742 cut / 0 rapids to a correct 737 cut / 5 rapids (its 5 `G0` moves). Geometry is unchanged
-(only the `kind` column shifts); FDM output is byte-identical since `Cut` is never evaluated there.

-feat(dialects): promote grbl-laser experimental → validated on hardware evidence (#189)
-
-First hardware-validation pass (DD-012 D8): a real GRBL/LightBurn diode-laser run — 6161 moves incl.
-fill + offset-fill, full 0–1000 `S` power ramp — confirmed machine-class detection, the Cut-vs-rapid
-split, and the `toolPower` channel against the physical cut (all claims ✓). `grbl-laser` is flipped
-`experimental → validated`: for laser files its `cutMoves`/`toolPower` claims now report **`known`**
-instead of `inferred`, and the `cnc-dialect-experimental` warning is no longer emitted.
-
-Scope is per-controller: `grbl-mill` and `linuxcnc` remain `experimental` (claims stay `inferred`)
-until a run on real CNC hardware. Evidence recorded in `docs/design/DD-012-hardware-validation-log.md`.

-feat: lexer handles multi-command lines, N-word line numbers, and bare S/F (#189)
-
-Real CNC/laser G-code (GRBL, LinuxCNC, TinyG, Mach3, Fanuc) is written very differently from FDM
-slicer output, and the inherited first-word lexer silently dropped most of it. The lexer now:
-
-- **Reads every G/M/T command word on a line**, not just the first — `G20 G17 G90`, `G91 G81 …`,
-  `S3400 M3` now all apply. This was the biggest gap: `M3` spindle-on and `G81` canned cycles were
-  being dropped as params, so mills showed no `Cut` moves and drilled holes vanished.
-- **Strips `N`-word line numbers** (`N10 G1 X…`) — Fanuc/Mach/TinyG number every line, which
-  previously reduced whole files to zero geometry.
-- **Latches bare `S` / `F` lines** (standalone `S1000` / `F600`) into modal power/feed — common in
-  GRBL-laser output.
-- Guards against **letters embedded in extended-command words** (`EXCLUDE_OBJECT … POLYGON=…`): a
-  command/param is only taken when a real number follows the letter, so `T` in `M486 T<count>` /
-  `M104 T<tool>` stays a parameter (not a tool select), and the `G` in `POLYGON` never becomes a move.
-
-Validated against real public sample files: a LinuxCNC arc-spiral went from 16 → 5,506 parsed
-segments, a TinyG program from 0 → 344. **FDM output is byte-identical** — slicers emit one clean
-command per line, so the multi-command path never runs for them (the real-G-code native-golden corpus
-is unchanged except for fewer spurious `unsupported-command` warnings; `demo-mach3` and one adversarial
-binary fixture are documented intentional divergences).

+
+  Two new `ColorMode`s consuming the [#189](https://github.com/ChestnutLabs/gcode-preview/issues/189) channels (DD-012 D7):
+  - **`power`** — ramps each segment's modal `toolPower` (laser power / spindle RPM, the `S` value) onto
+    a color ramp, the CNC/laser counterpart to color-by-speed. Auto-ranged (`toolPowerRange`) or explicit;
+    `NaN` (tool off) or a file parsed without the `toolPower` channel → fallback, never a fabricated color.
+    Capability-gated on `toolPower` (the Three renderer's `isColorModeAvailable` gates it).
+  - **`moveKind`** — cut-vs-rapid: productive moves (`Extrude` or `Cut`) vs rapids (`Travel`) — the
+    "where the tool is actually working" view. Reads the always-present `kind` channel, so it is always
+    available.
+
+  Both flow through `createSegmentColorer`, so the Three and Canvas-2D renderers get them for free. FDM
+  coloring is unchanged.

+### Minor Changes

+- [#258](https://github.com/ChestnutLabs/gcode-preview/pull/258) [`3f06e5b`](https://github.com/ChestnutLabs/gcode-preview/commit/3f06e5b7b6926daaad4290b29c577a380c9e10df) Thanks [@sobechestnut-dev](https://github.com/sobechestnut-dev)! - feat: evidence-based non-extrusion detection — recognize header-less real CNC/laser files ([#189](https://github.com/ChestnutLabs/gcode-preview/issues/189))
+
+  The phase-3 CNC/laser detectors were tuned on synthetic fixtures and matched **none** of the real
+  public samples (LaserGRBL, LinuxCNC, GRBL CAM output) — real controller output usually has **no
+  generator header** and writes commands **mid-line** and **concatenated** (`s3400 m3`, `g1z-.1`).
+
+  Detection is now **evidence-scored**, not banner-only:
+  - A shared `scoreEvidence` extractor strips comments (so `(M3)` / `; LinuxCNC` in a comment can't
+    create a false marker) and matches commands as words anywhere on a line.
+  - **GRBL laser** — LightBurn / `$32=1`, **or** the header-less form: a tool-on command (`M3`/`M4`) with
+    `S` power and **no Z-plunge** (lasers are planar).
+  - **GRBL / generic mill** — `M3` spindle that **plunges into negative Z** with no extrusion (a milling
+    fingerprint that separates it from a planar laser); banner optional.
+  - **LinuxCNC** — explicit header, **or** RS274NGC **O-word** subroutines/flow (`o100 sub`).
+  - Extrusion detection tightened to `E` on a **motion line**, so LinuxCNC `M67 E0 Q…` analog laser power
+    is no longer mistaken for FDM.
+
+  Real-file result: **0/6 → 3/6 detected, each with the correct machine class** (laser→laser, mill→mill,
+  LinuxCNC→linuxcnc); the misses are honest — files with a commented-out or absent spindle carry no
+  tool-state to infer. Still **experimental tier** (claims reported `inferred`) — detection working on
+  real files is one input; semantic ground truth (does our `Cut` = actual cutting, `S` scale) still wants
+  a real machine or a trusted reference.

+
+  Adds controller detection and the **validation-tier honesty mechanism** for CNC/laser toolpaths:
+  - New dialects (`@chestnutlabs/gcode-dialects`): **GRBL laser** (LightBurn / `$32` laser mode / `M4`+`S`),
+    **GRBL mill** and **LinuxCNC** (`M3` spindle, `%`/banner envelopes). Registered in the batteries worker.
+  - Each dialect adds provenance (`cnc.controller`, `cnc.machineClass`, `cnc.toolPowerLabel`) and a
+    **validation tier** (`cnc.validationTier`). Per DD-012 D6: an **experimental** dialect reports its
+    non-extrusion claims (`cutMoves` / `toolPower` / `cannedCycles`) as **`inferred`** (never `known`),
+    with a `cnc-dialect-experimental` disclosure — and only for claims the file actually made (an unused
+    feature is never fabricated).
+  - **All launch dialects ship `experimental`** (synthetic fixtures only). A single `tier: 'validated'`
+    flip per controller promotes its claims to `known` once confirmed on real hardware (DD-012 §8/§15).
+
+  Geometry is untouched (dialects only annotate/label). FDM detection is unaffected — CNC dialects do
+  not match FDM output.

+
+  First hardware-validation pass (DD-012 D8): a real GRBL/LightBurn diode-laser run — 6161 moves incl.
+  fill + offset-fill, full 0–1000 `S` power ramp — confirmed machine-class detection, the Cut-vs-rapid
+  split, and the `toolPower` channel against the physical cut (all claims ✓). `grbl-laser` is flipped
+  `experimental → validated`: for laser files its `cutMoves`/`toolPower` claims now report **`known`**
+  instead of `inferred`, and the `cnc-dialect-experimental` warning is no longer emitted.
+
+  Scope is per-controller: `grbl-mill` and `linuxcnc` remain `experimental` (claims stay `inferred`)
+  until a run on real CNC hardware. Evidence recorded in `docs/design/DD-012-hardware-validation-log.md`.

+
+  CNC canned drilling cycles previously produced **zero geometry** — holes vanished. They now expand to
+  explicit sub-moves so the drilling is real, classified toolpath:
+  - **G81/G82** (drill / drill-with-dwell): rapid to the hole XY, rapid down to the R plane, **feed to
+    depth (`Cut`)**, rapid retract.
+  - **G83** (peck): the plunge is a peck loop — feed down by `Q`, rapid-retract to R between pecks, until
+    reaching depth; each down-feed is a `Cut`.
+  - **G98/G99** set the retract plane (initial Z vs R); **G80** cancels; a `G0`–`G3` motion also cancels.
+  - **Modal repeat**: with a cycle active, a bare `X`/`Y` line drills another hole (retaining Z/R/Q and
+    the initial plane) — the common CNC hole-pattern form.
+  - Rapids are `Travel`, plunges are `Cut`; new capability **`cannedCycles`** (`known` once a cycle is
+    seen, else `unavailable`).
+
+  FDM output is unchanged (no canned cycles in FDM); the native-golden corpus gains only the additive
+  `cannedCycles` capability, with no geometry change.

+
+  Non-extrusion toolpaths (CNC / laser / plotter) no longer collapse their productive moves into
+  `Travel`. The parser now tracks a tool-engaged modal state — `M3`/`M4` (spindle/laser on, incl. the
+  `M03`/`M04` leading-zero form) engage it, `M5` disengages — and classifies a move with **no extrusion
+  `E`** while the tool is engaged as the new **`MoveKind.Cut`** bit (a CNC/laser/plotter counterpart to
+  `Extrude`, composing with `ArcSegment` like the other kinds).
+  - New IR move kind `MoveKind.Cut = 1 << 7` (`@chestnutlabs/toolpath-core`).
+  - New capability **`cutMoves`**: `known` once a tool-state modal is seen (a CNC/laser/plotter file),
+    `unavailable` for FDM.
+  - **FDM is byte-identical**: FDM slices never issue `M3`/`M4`, so `Cut` is never set and every move
+    stays `Extrude`/`Travel` exactly as before (verified against the native-golden corpus; the CNC
+    fixtures `demo-easel`/`demo-mach3` are documented intentional adapter-divergences).
+
+  Modal tool-state _value_ channels (laser power / spindle RPM via `S`), canned-cycle expansion, and
+  dialect families follow in later DD-012 phases.

+
+  CNC/LinuxCNC-style G-code frequently omits the `G` word on repeated moves (`G1 X0 Y0` then bare
+  `X10 Y0` / `X20 Y0`). The parser previously **dropped** those lines entirely — a three-move path
+  produced a single segment. It now tracks the active `G0`–`G3` motion mode and treats a line whose
+  leading word is a coordinate axis (`X`/`Y`/`Z`, with no `G`/`M`/`T` command) as a continuation of
+  that mode, so the full toolpath is emitted and classified/colored consistently (incl. inline `S`
+  for `toolPower`).
+
+  FDM output is **byte-identical** — slicers always emit the `G` word, so the continuation path never
+  triggers (the native-golden corpus is unchanged). This unblocks canned-cycle repeat (next phase).

+
+  Adds the shared, opt-in **`ModalChannel`** mechanism DD-012 D3 is built around, and its first channel:
+  **`toolPower`** — the modal spindle/laser `S` value while a tool is engaged.
+  - `ParseOptions.modalChannels?: readonly string[]` — request per-segment modal channels by id.
+    Supported id: `'toolPower'`. Unknown ids are ignored with a `modal-channel-unsupported` warning.
+  - `ToolpathSegments.modal?: Readonly<Record<string, Float32Array>>` — one Float32 column per requested
+    channel, present **only** when requested. An unset value is `NaN` (an honest "no value here"), never
+    a fabricated `0`. `toolPower` is the modal `S` (set on `M3`/`M4` and inline on GRBL-laser motion
+    lines) while engaged, `NaN` when the tool is off (`M5`).
+  - New capability **`toolPower`**: surfaced only when the channel is requested — `known` once a
+    tool-state modal is seen, else `unavailable`.
+  - **Default parse pays nothing**: no `modalChannels` ⇒ no `modal` on the IR, no extra columns, FDM
+    output unchanged. The budget-aware SoA writer (DD-003) grows the opt-in columns in lockstep and
+    accounts their bytes.
+
+  Presentation (Watts vs RPM) is a dialect label, not a separate channel (DD-012 D4); [#180](https://github.com/ChestnutLabs/gcode-preview/issues/180)'s
+  fan/temp/accel color channels reuse this same mechanism in a later phase.
+
+- [#256](https://github.com/ChestnutLabs/gcode-preview/pull/256) [`b84bea9`](https://github.com/ChestnutLabs/gcode-preview/commit/b84bea959b7aae24d148e6bcc488a9ed254a54f0) Thanks [@sobechestnut-dev](https://github.com/sobechestnut-dev)! - feat: lexer handles multi-command lines, N-word line numbers, and bare S/F ([#189](https://github.com/ChestnutLabs/gcode-preview/issues/189))
+
+  Real CNC/laser G-code (GRBL, LinuxCNC, TinyG, Mach3, Fanuc) is written very differently from FDM
+  slicer output, and the inherited first-word lexer silently dropped most of it. The lexer now:
+  - **Reads every G/M/T command word on a line**, not just the first — `G20 G17 G90`, `G91 G81 …`,
+    `S3400 M3` now all apply. This was the biggest gap: `M3` spindle-on and `G81` canned cycles were
+    being dropped as params, so mills showed no `Cut` moves and drilled holes vanished.
+  - **Strips `N`-word line numbers** (`N10 G1 X…`) — Fanuc/Mach/TinyG number every line, which
+    previously reduced whole files to zero geometry.
+  - **Latches bare `S` / `F` lines** (standalone `S1000` / `F600`) into modal power/feed — common in
+    GRBL-laser output.
+  - Guards against **letters embedded in extended-command words** (`EXCLUDE_OBJECT … POLYGON=…`): a
+    command/param is only taken when a real number follows the letter, so `T` in `M486 T<count>` /
+    `M104 T<tool>` stays a parameter (not a tool select), and the `G` in `POLYGON` never becomes a move.
+
+  Validated against real public sample files: a LinuxCNC arc-spiral went from 16 → 5,506 parsed
+  segments, a TinyG program from 0 → 344. **FDM output is byte-identical** — slicers emit one clean
+  command per line, so the multi-command path never runs for them (the real-G-code native-golden corpus
+  is unchanged except for fewer spurious `unsupported-command` warnings; `demo-mach3` and one adversarial
+  binary fixture are documented intentional divergences).

+- [#260](https://github.com/ChestnutLabs/gcode-preview/pull/260) [`879b60a`](https://github.com/ChestnutLabs/gcode-preview/commit/879b60ae0fca87ca8187791603a1bc7f54e61c4c) Thanks [@sobechestnut-dev](https://github.com/sobechestnut-dev)! - fix: G0 rapids classify as Travel, not Cut, even while the tool is engaged ([#189](https://github.com/ChestnutLabs/gcode-preview/issues/189))
+
+  The non-extrusion `Cut`/`Travel` classifier keyed only on tool-state (`M3`/`M4` latched), so on a
+  router — where the spindle stays on across rapids — every `G0` reposition was counted as a cutting
+  move. DD-012 D2 §4.2 already specifies that rapids stay `Travel`; this brings the implementation in
+  line: only a **feed** move (`G1`/`G2`/`G3`) with the tool engaged and no `E` delta is `Cut`; a `G0`
+  rapid is `Travel` regardless of tool state (a GRBL-laser also gates the beam off during `G0`).
+
+  Surfaced by the CNC/laser validation harness on real files — e.g. the `easel` router fixture went
+  from 742 cut / 0 rapids to a correct 737 cut / 5 rapids (its 5 `G0` moves). Geometry is unchanged
+  (only the `kind` column shifts); FDM output is byte-identical since `Cut` is never evaluated there.

+
+  Two new `ColorMode`s consuming the [#189](https://github.com/ChestnutLabs/gcode-preview/issues/189) channels (DD-012 D7):
+  - **`power`** — ramps each segment's modal `toolPower` (laser power / spindle RPM, the `S` value) onto
+    a color ramp, the CNC/laser counterpart to color-by-speed. Auto-ranged (`toolPowerRange`) or explicit;
+    `NaN` (tool off) or a file parsed without the `toolPower` channel → fallback, never a fabricated color.
+    Capability-gated on `toolPower` (the Three renderer's `isColorModeAvailable` gates it).
+  - **`moveKind`** — cut-vs-rapid: productive moves (`Extrude` or `Cut`) vs rapids (`Travel`) — the
+    "where the tool is actually working" view. Reads the always-present `kind` channel, so it is always
+    available.
+
+  Both flow through `createSegmentColorer`, so the Three and Canvas-2D renderers get them for free. FDM
+  coloring is unchanged.

 # @chestnutlabs/toolpath-core
 
+## 0.4.0

+### Minor Changes
+
+- [#248](https://github.com/ChestnutLabs/gcode-preview/pull/248) [`1029580`](https://github.com/ChestnutLabs/gcode-preview/commit/10295803839816adaed224c48eba1f74374c0c2a) Thanks [@sobechestnut-dev](https://github.com/sobechestnut-dev)! - feat: non-extrusion `Cut` move classification + tool-state modal (DD-012 phase 1, [#189](https://github.com/ChestnutLabs/gcode-preview/issues/189))
+
+  Non-extrusion toolpaths (CNC / laser / plotter) no longer collapse their productive moves into
+  `Travel`. The parser now tracks a tool-engaged modal state — `M3`/`M4` (spindle/laser on, incl. the
+  `M03`/`M04` leading-zero form) engage it, `M5` disengages — and classifies a move with **no extrusion
+  `E`** while the tool is engaged as the new **`MoveKind.Cut`** bit (a CNC/laser/plotter counterpart to
+  `Extrude`, composing with `ArcSegment` like the other kinds).
+  - New IR move kind `MoveKind.Cut = 1 << 7` (`@chestnutlabs/toolpath-core`).
+  - New capability **`cutMoves`**: `known` once a tool-state modal is seen (a CNC/laser/plotter file),
+    `unavailable` for FDM.
+  - **FDM is byte-identical**: FDM slices never issue `M3`/`M4`, so `Cut` is never set and every move
+    stays `Extrude`/`Travel` exactly as before (verified against the native-golden corpus; the CNC
+    fixtures `demo-easel`/`demo-mach3` are documented intentional adapter-divergences).
+
+  Modal tool-state _value_ channels (laser power / spindle RPM via `S`), canned-cycle expansion, and
+  dialect families follow in later DD-012 phases.
+
+- [#250](https://github.com/ChestnutLabs/gcode-preview/pull/250) [`8fec7c3`](https://github.com/ChestnutLabs/gcode-preview/commit/8fec7c3622cd2a6d6d57b43d7866cfea1cb71e09) Thanks [@sobechestnut-dev](https://github.com/sobechestnut-dev)! - feat: opt-in modal tool-power channel (DD-012 phase 1 — the `ModalChannel` mechanism, [#189](https://github.com/ChestnutLabs/gcode-preview/issues/189))
+
+  Adds the shared, opt-in **`ModalChannel`** mechanism DD-012 D3 is built around, and its first channel:
+  **`toolPower`** — the modal spindle/laser `S` value while a tool is engaged.
+  - `ParseOptions.modalChannels?: readonly string[]` — request per-segment modal channels by id.
+    Supported id: `'toolPower'`. Unknown ids are ignored with a `modal-channel-unsupported` warning.
+  - `ToolpathSegments.modal?: Readonly<Record<string, Float32Array>>` — one Float32 column per requested
+    channel, present **only** when requested. An unset value is `NaN` (an honest "no value here"), never
+    a fabricated `0`. `toolPower` is the modal `S` (set on `M3`/`M4` and inline on GRBL-laser motion
+    lines) while engaged, `NaN` when the tool is off (`M5`).
+  - New capability **`toolPower`**: surfaced only when the channel is requested — `known` once a
+    tool-state modal is seen, else `unavailable`.
+  - **Default parse pays nothing**: no `modalChannels` ⇒ no `modal` on the IR, no extra columns, FDM
+    output unchanged. The budget-aware SoA writer (DD-003) grows the opt-in columns in lockstep and
+    accounts their bytes.
+
+  Presentation (Watts vs RPM) is a dialect label, not a separate channel (DD-012 D4); [#180](https://github.com/ChestnutLabs/gcode-preview/issues/180)'s
+  fan/temp/accel color channels reuse this same mechanism in a later phase.
