Spun off 2026-05-03 from the closed-without-patch kwin_overlay_subsurface campaign (its phase8_handover.md is the predecessor). The candidate research question is whether running an X11 session on PineTab2 reproduces, eliminates, or transforms the drop-inversion phenomenon that motivated the predecessor — but the framing is provisional and awaits operator confirmation before Phase 1 lock. phase0_findings.md is the substrate doc: - Predecessor close-out summary (three reasons no patch landed; replicate-baseline-first lesson). - What stays valid from the predecessor (Phase 1 scanout archaeology, Phase 2-prime KWin Wayland source-read which does NOT transfer to X11, Δ_present-46ms reproducible side-finding which is directly testable under X11, measurement infrastructure with WAYLAND_DEBUG-specific parts that don't transfer). - Current ohm state (carry-over predecessor tooling, governor pin, baloo disabled, kwin-fourier still installed). - Provisional research question with three plausible outcomes (α/β/γ) and four alternate framings the operator may have in mind that this question doesn't cover. - Working-assumption out-of-scope list (no patches, no MRs, no Δ_present chase yet). - Four pre-question Phase 0 deliverables that are unblocked regardless of framing: ohm state snapshot, X11-path inventory, X11 measurement-tool inventory, A1 Wayland-baseline rep on this campaign's session for future comparison anchor. worklist.md tracks Phase 0 only. Phase 1 lock awaits the research question. Discipline carry-overs from kwin_overlay_subsurface listed (replicate baseline first; phase discipline; non-upstreaming default; memory persistence at close). README.md status banner: Phase 0 in progress, research question pending operator confirmation. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

# Work items — x11-session-research
|
||
|
||
## Phase 0 — substrate + research question framing
|
||
|
||
**Status: IN PROGRESS.** Substrate doc landed
|
||
(`phase0_findings.md`). Research question is provisional,
|
||
awaits operator confirmation. Pre-question Phase 0 deliverables
|
||
listed below are unblocked.
|
||
|
||
- [x] Predecessor close-out summarised. Substrate doc
|
||
(`phase0_findings.md`) lists what stays valid from
|
||
`kwin_overlay_subsurface`, what's specific to Wayland and
|
||
doesn't transfer, and three plausible outcome shapes (α/β/γ)
|
||
for the candidate research question.
|
||
- [ ] **Operator confirms the research question.** Three
|
||
candidate framings + four alternates are listed in
|
||
`phase0_findings.md` § "Research question (provisional)".
|
||
Pick one (or correct the framing) before Phase 1.
|
||
- [ ] State snapshot of ohm under current Plasma Wayland —
|
||
the campaign-start *before* photo. Unattended-tractable.
|
||
- [ ] Inventory of available X11 paths on ohm: installed
|
||
packages, SDDM-advertised sessions, alternate WMs,
|
||
XWayland availability. Read-only.
|
||
- [ ] Inventory of measurement instruments that work under
|
||
X11. `xtrace`, frame-timing tooling, perf on Xorg PID, etc.
|
||
Read-only.
|
||
- [ ] A1 baseline: 1× `kwin_timing_nodebug`-equivalent run
|
||
on current Plasma Wayland session, captured into
|
||
`phase0_evidence/wayland_baseline_rep1/`. Same-session
|
||
anchor for any future X11 comparison.
|
||
|
||
## Phase 1 — locked research question + binding cells
|
||
|
||
**Pending operator confirmation of the Phase 0 question.**
|
||
Phase 1 lock will produce `phase1_lock.md` with binding cells
|
||
specific to whichever framing is locked.
|
||
|
||
## Phase 2-onwards
|
||
|
||
Pending.
|
||
|
||
## Discipline carry-overs from `kwin_overlay_subsurface`
|
||
|
||
- *Replicate the baseline first* — per
|
||
`feedback_replicate_baseline_first.md`. Phase 0 task "A1
|
||
baseline" exists specifically because of this lesson; do not
|
||
skip it.
|
||
- *Phase discipline* — no patches before source-read is
|
||
documented. Re-scoping must be honest about deferral target.
|
||
- *Non-upstreaming default* — bug reports + MRs are explicit
|
||
operator-tasked decisions.
|
||
- *Memory persistence rule* — when this campaign reaches its
|
||
diagnostic terminal state (success or honest closure), update
|
||
`project_campaign_overview.md` and add any new feedback
|
||
memory worth carrying forward to the next campaign.
