Sim Config Coverage Promotion Analysis

This analysis records how the completed virtual HAL changes the next linuxcnc/configs/sim coverage-promotion work. It is intentionally an analysis document only: it does not promote rows, change inventory counts, or relax any blocked runtime family.

Current Baseline

Current machine-readable inventory remains:

sim_configs_wasm_node_inventory_executed=28
sim_configs_wasm_node_inventory_passed=28
sim_configs_wasm_node_inventory_skipped=131
sim_configs_wasm_node_inventory_unexpected_fail=0
sim_configs_wasm_node_inventory_skip_ASSET_ONLY=65
sim_configs_wasm_node_inventory_skip_L4_PYTHON_REMAP=53
sim_configs_wasm_node_inventory_skip_L4_TOOL_DB=1
sim_configs_wasm_node_inventory_skip_L4_USER_M_PROCESS=1
sim_configs_wasm_node_inventory_skip_NON_MAIN_CLASS=10
sim_configs_wasm_node_inventory_skip_UPSTREAM_DEMO=1

The current generated inventory has no skipped main-program row whose hard block is already empty. That matters: virtual HAL maturity should not be used as a blanket reason to reduce skipped=131. The next useful promotions are case promotions from Node inventory or representative coverage into browser, diagnostics, and release evidence.

What Virtual HAL Unlocks

The virtual HAL is now a source-derived Web simulation replacement for these runtime surfaces:

• LinuxCNC realtime HAL simulation replacement;
• halcmd simulation replacement;
• motion controller simulation replacement;
• HAL pin/signal/param store;
• setp, sets, net, show, getp, gets, loadrt, loadusr, addf, start, and stop command workflow;
• servo-period motion stepping;
• axis/joint position feedback;
• source-compliance, sim-config source coverage, command fixture, and motion matrix reports;
• OPFS/session persistence and release diagnostics evidence.

That means Web coverage can now promote additional cases when their remaining dependency is HAL, HALUI, deterministic virtual halcmd, machine state, or motion feedback. It does not unlock rows whose defining behavior is Python remap runtime, tool database process protocol, external user-M process state, or upstream-invalid demo code.

Promotion Rules After Virtual HAL

A sim-config case can move forward only when all of these are true:

1. LinuxCNC source/config evidence owns the behavior.
2. Native or current Node inventory evidence already passes, or the row is a macro/load or subroutine class with an explicit non-main validation plan.
3. Dependencies are limited to virtual HAL, HALUI, deterministic UI process declarations, machine files, tool tables, remap subroutine assets, or motion/kinematics evidence already covered by LinuxCNC-backed runtime.
4. Browser evidence can export virtual HAL source compliance, sim-config source coverage, command fixtures, and manifest-backed motion matrix.
5. The row is not L4-PYTHON-REMAP, L4-TOOL-DB, L4-USER-M-PROCESS, or UPSTREAM-DEMO.
6. verify_no_standalone_cnc_semantics.sh remains green.

Promotion should mean a stronger evidence tier, not necessarily a lower skip count. For example, a row may move from Node INV to browser diagnostics evidence while the inventory baseline remains executed=28.

Recommended Promotion Candidates

Tier 1: Browser Evidence For Existing Node INV Rows

These rows already pass Node inventory and have no hard runtime block. Virtual HAL makes them good candidates for browser diagnostics/release evidence rather than only shared representative coverage.

Candidate	Current coverage	Why it is now promotable
qtdragon/qtdragon_multi_joint/on_abort.ngc	Node INV, browser delegated to woodpecker	Requires HAL/UI declarations and multi-joint machine context; virtual HAL motion matrix already maps qtdragon-on-abort and qtdragon_xyyz.ini.
qtdragon/qtdragon_xyz/on_abort.ngc	Node INV, browser delegated to woodpecker	Same on-abort family, already part of virtual HAL sim-config source coverage evidence.
qtdragon/qtdragon_xyz45/on_abort.ngc	Node INV, browser delegated to woodpecker	Adds rotary-axis machine context without requiring Python remap or external process runtime.
qtdragon_hd/qtdragon_hd_xyz/on_abort.ngc	Node INV, browser delegated to woodpecker	Deterministic UI/HAL family, suitable for browser diagnostics artifact evidence.
qtdragon_hd/qtdragon_hd_z_compensation/on_abort.ngc	Node INV, browser delegated to woodpecker	HAL/UI machine state case; should be promoted only with explicit source evidence for the z-compensation INI.
qtvcp_screens/qtdragon/on_abort.ngc	Node INV, browser delegated to woodpecker	QTVCP on-abort surface, no Python-remap hard block in inventory.
axis/vismach/puma/puma_seam_weld.ngc	Node INV, browser represented by puma_cube.ngc	Same vendored PUMA machine context; virtual HAL motion matrix already includes vismach-remap-sims and puma.ini.
axis/rose_engine/rcone_demo.ngc	Node INV	HAL process only, no hard block; useful as a non-Qt/non-vismach browser diagnostics candidate.

Expected next artifact shape:

• extend a source-derived candidate list in SDK or docs;
• add browser diagnostics fixture rows, not a JS CNC interpretation path;
• assert virtual HAL source compliance, sim-config source coverage, command fixtures, and motion matrix remain complete;
• update matrix notes from delegated browser representative to explicit browser evidence only after the browser gate exists.

Tier 2: Existing REP Rows Worth Splitting Into More Cases

These are already promoted as representative coverage. The next work is not to prove the class exists; it is to split representative buckets into more specific cases now that virtual HAL can carry machine state evidence.

Candidate	Current coverage	Promotion goal
axis/vismach/5axis/bridgemill/5axisgui.ngc	Node/browser REP	Add explicit HALUI MDI and W-axis diagnostics evidence.
axis/vismach/5axis/table-dual-rotary/demos/xyzab-tdr-demo.ngc	Node/browser REP	Add dual-rotary ABC/AB feedback evidence in motion matrix rows.
axis/vismach/5axis/table-rotary-tilting/demos/boat-xyzac.ngc	Node/browser REP	Add TRT machine-family diagnostics evidence separate from generic 5-axis class.
axis/vismach/melfa-sim/example.ngc	Node/browser REP	Add robot/Genser remap-machine evidence with source files and session diagnostics.
axis/vismach/puma/puma_cube.ngc	Node/browser REP	Keep as PUMA representative but pair with puma_seam_weld.ngc Node INV evidence.

Tier 3: Macro/Load Rows With No Hard Runtime Block

These rows are not standalone main-program targets, so they should not be promoted by executing them as browser main programs. They can move forward as explicit macro/load fixtures if the gate names them as non-main class evidence.

Candidate	Current status	Promotion goal
axis/external_offsets/queuebuster.ngc	NON_MAIN_CLASS	Add external-offset macro/load source fixture next to circles.ngc.
axis/lathe-fanucy/toolchange.ngc	NON_MAIN_CLASS	Add macro/load fixture if the lathe-fanucy INI/tool context is vendored.
axis/rose_engine/rcone.ngc	inventory-only macro/load	Pair with rcone_demo.ngc to prove rose-engine support assets load.
gscreen/industrial_lathe_wear/toolchange.ngc	inventory-only macro/load	Candidate only if kept as macro/load evidence, not UI process emulation.
gscreen/silverdragon/macros/*.ngc	inventory-only macro/load	Candidate for a small macro fixture subset, not all macros at once.
qtvcp_screens/industrial_lathe_wear/toolchange.ngc	inventory-only macro/load	Candidate only as non-main fixture evidence.

Rows Still Not Promotable

Virtual HAL does not change these blocked decisions:

• L4-PYTHON-REMAP: still requires LinuxCNC-owned Python remap runtime proof. Examples include laser, many axis/remap/*, gmoccapy macro families, and table-rotary-spindle-nutating TWP demos.
• L4-TOOL-DB: axis/db_demo/base.ngc still requires tool database process protocol proof, not only HAL state.
• L4-USER-M-PROCESS: axis/vismach/millturn/example.ngc still requires external USER_M_PATH process state proof for M128/M129.
• UPSTREAM-DEMO: incremental_repetition_g533.ngc remains a preserved upstream demo edge and must not be forced to pass by standalone semantics.
• ASSET-ONLY: remap subroutines remain validated by parse/remap or owning main-program context, not standalone browser execution.

Proposed Next Batch

The next implementation batch should avoid changing the inventory baseline. It should add a promotion-candidate report and one or two browser evidence fixtures.

Recommended first slice:

1. Add a machine-readable candidate report for Tier 1 rows: qtdragon-on-abort, puma-seam-weld, and rose-engine.
2. Require every row to name LinuxCNC source files, INI files, G-code files, dependency class, current Node status, and target browser evidence.
3. Add Node gate assertions that no candidate is in L4-PYTHON-REMAP, L4-TOOL-DB, L4-USER-M-PROCESS, UPSTREAM-DEMO, or ASSET-ONLY.
4. Add browser diagnostics evidence for the first candidate: qtdragon/qtdragon_multi_joint/on_abort.ngc.
5. Keep sim_configs_wasm_node_inventory_executed=28, sim_configs_wasm_node_inventory_passed=28, and sim_configs_wasm_node_inventory_skipped=131 unchanged until a deliberate inventory-promotion patch is made.

Recommended gates:

wasm-port/tests/sdk/node/verify_sdk_surface.sh
SKIP_INTERP_BUILD=1 wasm-port/tests/browser/verify_real_simulation_browser.sh

2026-06-18 QtDragon Family Promotion Evidence

The first promotion-candidate gate has now been extended from a single qtdragon/qtdragon_multi_joint/on_abort.ngc row to the full QtDragon on-abort family:

• qtdragon/qtdragon_multi_joint/on_abort.ngc
• qtdragon/qtdragon_xyz/on_abort.ngc
• qtdragon/qtdragon_xyz45/on_abort.ngc
• qtdragon_hd/qtdragon_hd_xyz/on_abort.ngc
• qtdragon_hd/qtdragon_hd_z_compensation/on_abort.ngc
• qtvcp_screens/qtdragon/on_abort.ngc

The implementation remains a diagnostics/evidence promotion, not an inventory baseline change. The rows still report Node inventory PASS with matrix INV, but the virtual HAL promotion candidate report and real browser diagnostics artifact now require every QtDragon candidate to be complete, to name its LinuxCNC INI and G-code source files, to keep currentNodeInventoryStatus === "PASS", and to target explicit-browser-diagnostics.

The virtual HAL sim-config source coverage target also includes the previously missing QtDragon qtdragon_xyz45 and qtdragon_hd_z_compensation INI/program source files. This keeps the report source-derived from vendored LinuxCNC machine files rather than browser-owned CNC behavior.

Inventory baseline remains:

sim_configs_wasm_node_inventory_executed=28
sim_configs_wasm_node_inventory_passed=28
sim_configs_wasm_node_inventory_skipped=131
sim_configs_wasm_node_inventory_unexpected_fail=0

2026-06-18 Non-Qt Promotion Evidence

The promotion-candidate release gate has now been extended beyond QtDragon to the two Tier 1 non-Qt candidates:

• axis/vismach/puma/puma_seam_weld.ngc
• axis/rose_engine/rcone_demo.ngc

The required candidate set now covers all eight source-derived Tier 1 rows: the six QtDragon on-abort candidates, PUMA seam weld, and rose-engine cone demo. Release diagnostics validation requires the PUMA row to include puma.ini, puma_seam_weld.ngc, and the LinuxCNC remap subroutine source remap_subs/428remap.ngc. It also requires the rose-engine row to include rose_engine.ini and rcone_demo.ngc.

This still does not change inventory promotion counts. Both rows remain Node inventory PASS with matrix INV; the added value is explicit browser diagnostics evidence and release-gate enforcement that the virtual HAL reports are complete for non-Qt sim-config families.

2026-06-18 Macro/Load Non-Main Fixture Evidence

The virtual HAL diagnostics evidence now includes an explicit macro/load fixture report:

• VIRTUAL_HAL_SIM_CONFIG_MACRO_LOAD_FIXTURES
• createVirtualHalSimConfigMacroLoadFixtureReport()

The first required non-main fixtures are:

• axis/rose_engine/rcone.ngc
• axis/external_offsets/queuebuster.ngc

The rose-engine fixture is paired with rcone_demo.ngc and keeps rcone.ngc as a non-main macro/load asset. The external-offsets fixture records queuebuster.ngc as a declared NGCGUI_SUBFILE through eoffsets.ini; the fixture path is preserved for diagnostics, while the manifest-backed source evidence is the owning INI and paired LinuxCNC program source. This avoids pretending that queuebuster.ngc is a standalone browser main program.

Release diagnostics validation now requires virtualHalSimConfigMacroLoadFixtures to be present and ready. The report must keep inventoryBaselineUnchanged === true, every row must have nonMainFixture === true, and standaloneMainViolations must stay empty.

2026-06-18 Macro/Load Blocked Fixture Lock

The macro/load report now also carries a blocked-fixture lock. This is a negative evidence gate: it proves selected macro/load paths are not included in positive virtual HAL fixtures when their owner boundary is still unavailable or outside the virtual HAL scope.

The first blocked fixture rows are:

• gscreen/silverdragon/macros/tool_sensor.ngc
• gmoccapy/macros/on_abort.ngc

tool_sensor.ngc is intentionally not promoted because the owning gscreen/silverdragon/silverdragon.ini machine file is not available in the vendored manifest, and promoting it would require a Python UI/process boundary proof rather than virtual HAL diagnostics alone. gmoccapy/macros/on_abort.ngc remains locked behind L4-PYTHON-REMAP and LinuxCNC-owned Python remap/prolog/epilog runtime proof.

Release diagnostics validation now requires blockedFixturePromotionViolations to stay empty and requires both blocked rows to be excluded from positive macro/load fixtures. This prevents virtual HAL from accidentally unlocking Python UI or Python remap families.

The next practical slice is to add a machine-readable candidate audit for other UI-family macro/load rows before promoting any new positive fixture.

2026-06-18 UI-Family Macro/Load Candidate Audit

The macro/load report now carries audit rows for UI-family fixture candidates that are not ready for positive promotion:

• gscreen/industrial_lathe_wear/toolchange.ngc
• qtvcp_screens/industrial_lathe_wear/toolchange.ngc

Both rows are recorded as blocked-missing-owning-ini audit candidates with promotionAllowed === false. They must remain excluded from positive macro/load fixtures until the owning INI, machine files, tool table, and UI/process declaration have LinuxCNC source evidence that does not require Python UI process emulation.

Release diagnostics validation now requires auditPromotionViolations to stay empty and requires both audit rows to be present as negative evidence. This is an audit gate, not a coverage promotion: inventory baseline remains unchanged.

2026-06-18 UI-Family Audit Boundary Evidence

The UI-family audit rows now carry machine-readable source evidence from the generated inventory boundary artifacts:

• wasm-port/build/wasm/sim-configs-inventory/boundary-summary.tsv
• wasm-port/build/wasm/sim-configs-inventory/ini-boundary-summary.tsv

For both industrial-lathe toolchange.ngc rows, the audit evidence requires recommendedBlocked === "UNAVAILABLE" and a missing_vendored_ini:* dependency for the owning INI. The INI-level row must also report vendored === 0 and reportAvailable === 0.

The macro/load fixture report now exposes:

• missingAuditRows
• auditBoundaryEvidenceViolations
• auditPromotionAllowedViolations

Release diagnostics validation requires all of those lists to stay empty. This adds negative coverage for three failure modes: audit rows missing, audit rows accidentally promoted into positive fixtures, and promotionAllowed === true without generated boundary/source proof.

2026-06-18 SilverDragon Blocked Boundary Evidence

The blocked macro/load fixture rows now use the same generated boundary evidence contract. gscreen/silverdragon/macros/tool_sensor.ngc carries evidence from boundary-summary.tsv and ini-boundary-summary.tsv showing that the owning gscreen/silverdragon/silverdragon.ini is unavailable in the vendored inventory.

The report now exposes blockedBoundaryEvidenceViolations, and release diagnostics validation requires it to stay empty. This keeps the SilverDragon row as a blocked negative fixture with source-derived evidence, not a virtual HAL promotion path.

2026-06-18 Queuebuster Declaration Evidence

The declared-only axis/external_offsets/queuebuster.ngc fixture now carries declaration-level evidence from eoffsets.ini. The fixture report requires the owning INI to expose:

• section: DISPLAY
• key: NGCGUI_SUBFILE
• value: queuebuster.ngc
• source line: NGCGUI_SUBFILE = queuebuster.ngc

This keeps queuebuster.ngc as a non-main fixture path declared by LinuxCNC configuration, not a standalone browser main program. Release diagnostics validation now requires declarationEvidenceViolations to stay empty.

2026-06-18 Rose Engine Declaration Evidence

The positive axis/rose_engine/rcone.ngc non-main fixture now carries the same declaration-level evidence contract as queuebuster. rose_engine.ini declares the fixture with NGCGUI_SUBFILE = rcone.ngc, and the macro/load report now requires every positive fixture with a declarationSource to carry matching source evidence.

This keeps rcone.ngc as a LinuxCNC-declared macro/load support asset paired with rcone_demo.ngc, not a standalone browser main program. The evidence is limited to the owning INI declaration and does not add browser-owned G-code, interpreter, planner, or remap behavior.

2026-06-18 Boundary Evidence Freshness Gate

Generated boundary evidence for blocked and audit-only macro/load rows now carries an inventory baselineSummary. The macro/load report requires that summary to match the current generated inventory baseline:

executed=28
passed=28
skipped=131
unexpectedFail=0

This makes boundary-summary.tsv and ini-boundary-summary.tsv evidence explicitly tied to the current inventory baseline. A stale baseline now fails the blocked/audit boundary evidence gate instead of silently passing release diagnostics.

2026-06-18 Promotion Family URL Workflow Summary

The release readiness validation and URL workflow summaries now surface the promotion candidate familyRows as a user-visible summary. Ready artifacts show:

qtdragon-on-abort: 6/6 ready; vismach-remap-sims: 1/1 ready; rose-engine-rcone-demo: 1/1 ready

The ini-panel workflow overview URL summary reuses this value, so the QtDragon, PUMA, and rose-engine promotion families are visible without opening the raw diagnostics JSON. This is a presentation/reporting change only; it does not change inventory counts or CNC semantics.

2026-06-18 Structured Promotion Family Rows

The promotion family summary is now also exposed as structured rows. Each row records the family id, candidate count, complete count, source file count, and explicit browser diagnostics readiness. Current rows are:

qtdragon-on-abort: 6/6 ready; sources=12; diagnostics=ready
vismach-remap-sims: 1/1 ready; sources=3; diagnostics=ready
rose-engine-rcone-demo: 1/1 ready; sources=2; diagnostics=ready

The release readiness artifact, validation summary, URL workflow summary, and ini-panel workflow overview all expose these rows. This keeps the summary machine-readable while preserving the existing single-line text summary.

2026-06-18 Boundary Evidence Artifact Hash Gate

Generated boundary evidence now includes SHA-256 hashes for the two source TSV artifacts used by blocked and audit macro/load evidence:

boundary-summary.tsv de6cf57b7c07182e3bcb32e22dbdf202b618cabc14620d6dff1ef815587950b9
ini-boundary-summary.tsv b0afe27224e97a82fbecbbd75a7c86233c98fe957d9c1ba20f0656f8745a5eae

The macro/load report and release validation require those hashes to match. This extends the freshness gate beyond inventory counts and makes stale or substituted boundary TSV evidence fail the release diagnostics gate.

2026-06-18 Browser Promotion Family DOM Rows

The real browser simulation page now renders the structured promotion family rows in the diagnostics panel. The visible browser DOM exposes:

qtdragon-on-abort: 6/6 ready; sources=12
vismach-remap-sims: 1/1 ready; sources=3
rose-engine-rcone-demo: 1/1 ready; sources=2

The browser API also exposes getVirtualHalPromotionFamilyRows(), and the real simulation browser smoke asserts that the DOM rows, readiness dataset, and candidate report agree. This moves the existing source-derived promotion evidence from view-model/report data into a visible browser diagnostics surface. It does not change inventory counts or add CNC semantics.

2026-06-18 Fast Follow: Hash Tool And INI Panel Promotion DOM

The boundary TSV hash freshness gate now has an update/check helper:

wasm-port/tools/update_sim_config_boundary_hashes.sh --check
wasm-port/tools/update_sim_config_boundary_hashes.sh --write

The script computes SHA-256 for boundary-summary.tsv and ini-boundary-summary.tsv, then checks or updates the SDK/release validation constants. This removes the manual hash-update step after generated inventory artifacts change.

The ini-panel workflow overview now also has a dedicated promotion family DOM surface. It can render and mount the three structured promotion rows from the release URL workflow summary into [data-workflow-overview-promotion-family-rows]. The UI shell smoke verifies the rows mount as ready with the expected QtDragon, PUMA, and rose-engine values.

2026-06-18 Promotion Family Source Drilldown

Promotion family rows now carry their LinuxCNC source file lists through the release readiness report, validation summary, URL workflow summary, and ini-panel workflow overview render state. The ini-panel promotion family DOM mount renders the three family rows plus per-family source-file drilldown rows.

Current drilldown count is 17 source files:

qtdragon-on-abort: 12 source files
vismach-remap-sims: 3 source files
rose-engine-rcone-demo: 2 source files

This makes the browser/ini-panel evidence inspectable without opening the raw JSON artifact, while keeping the underlying behavior LinuxCNC-source-derived.

2026-06-18 Promotion Family Source Status

Each ini-panel promotion family source drilldown row now carries source status metadata:

• ini for LinuxCNC INI machine files;
• gcode for .ngc main/on-abort programs;
• remap-subroutine for files under remap_subs or nc_subroutines;
• manifest-backed for rows already carried by the source-derived promotion evidence.

The DOM render adds dataset fields for source kind, manifest-backed state, and source status, so the UI can distinguish machine config, G-code, and remap support evidence without changing any CNC semantics.

2026-06-18 Promotion Family Source Kind Counts

The ini-panel promotion family render state now aggregates source-kind counts per family and exposes them in the family row DOM dataset. Current counts are:

qtdragon-on-abort: ini=6 gcode=6
vismach-remap-sims: ini=1 gcode=1 remap-subroutine=1
rose-engine-rcone-demo: ini=1 gcode=1

The family row display includes this summary, while the per-source drilldown rows still expose individual source kind and manifest-backed status.

2026-06-18 Promotion Family Source Filter View Model

The ini-panel workflow overview now exposes a promotion family source filter view-model. It can filter the existing source drilldown by all, ini, gcode, remap-subroutine, or source, while preserving family grouping and source-kind counts.

Current filter totals are:

all=17
ini=8
gcode=8
remap-subroutine=1

The remap-subroutine filter currently resolves to the PUMA remap evidence row:

linuxcnc/configs/sim/axis/vismach/puma/remap_subs/428remap.ngc

This is a browser/UI evidence navigation helper only. It does not change the promotion candidate set, inventory baseline, or CNC runtime semantics.

2026-06-18 Promotion Family Source Family Filter

The source filter view-model now supports a second selector: familyId. This allows UI callers to scope source evidence by promotion family and then filter within that family by source kind.

Current family filter totals are:

all=17
qtdragon-on-abort=12
vismach-remap-sims=3
rose-engine-rcone-demo=2

For example, selecting virtual-hal-promotion-family-qtdragon-on-abort with gcode returns 6 QtDragon .ngc source rows from the 12-file family scope. The selector is a view-model feature only; it does not promote additional sim config rows or relax any blocked runtime family.

2026-06-18 Promotion Family Source Filter DOM Surface

The source filter view-model now has a dedicated DOM contract, readiness check, render helper, and mount helper. The DOM surface renders:

• family filter rows;
• source-kind filter rows;
• filtered source evidence rows;
• selected family/source-kind dataset fields on the mount node.

The QtDragon + gcode combination currently renders 13 DOM rows: 7 filter rows and 6 filtered source rows. This moves the combined evidence filter from a view-model-only helper into a mountable ini-panel workflow overview surface. It still only displays existing LinuxCNC-source-derived evidence.

2026-06-18 Promotion Family Source Filter Selector Controls

The source filter DOM surface now renders two selector controls in addition to the diagnostic rows:

• a family selector backed by familyFilters;
• a source-kind selector backed by sourceKindFilters.

For the QtDragon + gcode example, the controls expose the selected family virtual-hal-promotion-family-qtdragon-on-abort and selected source kind gcode, with the gcode option carrying count 6. The selectors currently render selection state and option metadata for browser integration; they do not change the underlying promotion evidence or add CNC semantics.

2026-06-18 Promotion Family Source Filter Selection Workflow

The selector controls now have an action-plan and selection-change workflow. The workflow reads the current family/source-kind selector values, derives the next source filter view-model, and can optionally re-render the source filter DOM surface.

The current smoke path changes from QtDragon + gcode to virtual-hal-promotion-family-rose-engine-rcone-demo + all. That produces a new view-model with 2 filtered source files from a 2-file family scope and re-renders the DOM rows to include rose-engine source evidence. This is still a host/UI workflow over existing source-derived evidence only.

2026-06-18 Promotion Family Source Filter Event Binding

The selector controls now have a reusable event binding helper. It binds the family and source-kind <select> elements to the selection-change workflow, tracks the last change result, and can unbind both controls.

The current Node smoke binds two selector controls, changes the family selector to virtual-hal-promotion-family-rose-engine-rcone-demo, dispatches a change event, and verifies that the source filter DOM re-renders with 2 rose-engine source rows. This keeps the browser integration path explicit without changing promotion status or CNC semantics.

Boundary Statement

This analysis relies on the improved virtual HAL only for Web simulation runtime surfaces. It does not claim Linux kernel hard-realtime ABI support, external hardware driver ABI support, native HAL module ABI support, Python UI process emulation, tool database process emulation, or external user-M process execution. G-code, interpreter, planner, kinematics, canonical motion, machine INI, tool table, parameter, and remap semantics remain LinuxCNC-backed.
