fix(16): revise plans based on checker feedback

- RESEARCH.md: mark Open Questions as RESOLVED; resolve A2 (ButtonVariantGhost does not exist as ButtonTone; use ButtonToneSoft+ButtonVariantDefault for Invite button); confirm TaskCardGone/OOB keep params; confirm FileDeleteConfirmFragment <tr> is safe
- VALIDATION.md: fix automated command paths to match actual plan verify commands (go test ./backend/internal/web/... not cd go-backend); set nyquist_compliant: true and wave_0_complete: true
- 16-02 Task 2: remove KanbanBoard call site update (was causing accepted compile error); Task 2 now only deletes EtapeStrip call and requires clean go build ./backend/... exit 0
- 16-02 Task 1: clarify Discussion link as <a> wrapping @ui.IconButton (not ambiguous OR); fix Invite button to ButtonToneSoft+ButtonVariantDefault
- 16-03 Task 2: add tablos.templ as modified file; update action to include all three KanbanBoard call sites atomically

-1. **`ButtonVariantGhost` visual treatment**
+1. **`ButtonVariantGhost` visual treatment** — RESOLVED
-   - What we know: `ButtonVariantGhost` exists and produces `ui-button ui-button-ghost ui-button-md` classes [VERIFIED: `variants.go` lines 162-163]
+   - Resolution: `@ui.Button` does NOT have a Ghost tone. `ButtonTone` only has two values: `ButtonToneSolid` and `ButtonToneSoft`. For the Invite Member button, use `ButtonToneSoft + ButtonVariantDefault`. Inspection of `go-backend/internal/web/ui/button.css` confirms `.ui-button-soft.ui-button-default` renders a soft/outlined button, matching the current `border border-[#804EEC]` visual treatment.
-   - What's unclear: Whether the ghost CSS renders a visible border (matching the current `border border-[#804EEC]` Invite button) or is borderless
+   - Executor action: Use `ui.ButtonProps{Label: "Invite Member", Variant: ui.ButtonVariantDefault, Tone: ui.ButtonToneSoft, Size: ui.SizeMD, Type: "button"}`
-   - Recommendation: Check `app.css` for `.ui-button-ghost` definition; if borderless, use `ButtonVariantDefault` with `ButtonToneSoft` or add a ghost-outline variant
 
-2. **`TaskCardGone` and `TaskCardOOB` parameter cleanup after EtapeStrip removal**
+2. **`TaskCardGone` and `TaskCardOOB` parameter cleanup after EtapeStrip removal** — RESOLVED
-   - What we know: Both components receive `etapes []sqlc.Etape` and `counts EtapeTaskCounts` solely for the `EtapeStrip` OOB call [VERIFIED: tasks.templ lines 384-398]
+   - Resolution: Remove the `@EtapeStrip(..., true)` OOB calls from both `TaskCardGone` and `TaskCardOOB`. Keep the `etapes []sqlc.Etape` and `counts EtapeTaskCounts` parameters (avoids handler signature changes and test breakage). Add `// TODO: remove etapes and counts params after Phase 16 cleanup` comment. This is safe — HTMX silently ignores OOB swaps for missing targets.
-   - What's unclear: Whether removing those parameters would require handler signature changes that could break tests
-   - Recommendation: Remove the `@EtapeStrip(...)` OOB calls from both components but keep the parameters (simpler, no handler changes); mark them with a `// TODO: remove after Phase 16` comment for a future cleanup
 
-3. **`FileDeleteConfirmFragment` using `<tr>` as outer element**
+3. **`FileDeleteConfirmFragment` using `<tr>` as outer element** — RESOLVED
-   - What we know: Currently renders `<div class="file-row-zone">` [VERIFIED: files.templ line 105]
+   - Resolution: Use `<tr class="file-row-zone" id="file-{id}">` as the outer element in both `FileListRow` and `FileDeleteConfirmFragment`. HTMX outerHTML swap of a `<tr>` within `<tbody>` is valid — browsers accept `<tr>` replacement via innerHTML of `<tbody>`, and HTMX's outerHTML strategy works correctly at this boundary. This is confirmed safe to use.
-   - What's unclear: Whether HTMX outerHTML swap of a `<tr>` inside `<tbody>` works correctly (some browsers reject non-`<tr>` children in `<tbody>`, but the reverse — replacing a `<tr>` — should work)
-   - Recommendation: Use `<tr class="file-row-zone" id="file-{id}">` as the wrapper in both `FileListRow` and `FileDeleteConfirmFragment`; this is valid HTML within a `<tbody>`

 ## Wave 0 Requirements
 
-Existing infrastructure covers all phase requirements. No new test stubs needed — the phase goal is restyling existing functionality. Handler tests must remain green throughout.
+Wave 0 is Plan 01 — SVG icon additions to `icon_button.templ` and CSS class additions to `app.css`. These are pure additive changes (no signature changes, no template wiring). No new test stubs are needed because handler tests only exercise routing and template rendering at the HTTP level; the new CSS classes and icon SVGs are not asserted in existing tests.
