MyAnythingList Handoff

handoff_2026-03-13_v01.html

This handoff captures the current state of the project after the logging-focused iterations through v23, the current canonical docs package v14, the real uploaded vision_en.html, and the latest uploaded runtime log. It is designed to let tomorrow’s session resume without depending on memory alone.

1. Current Known Good Signals

• Runtime logging is now useful enough to expose startup ordering and layout thrashing.
• QR behavior improved significantly in recent iterations: the user reported QR visible on launch and present in downloaded thumbnails.
• The log viewer itself is visible and usable.
• Canonical docs packaging is now back on the expected HTML + sortable-folder path.

2. Highest-Priority Remaining Problems

1. Thumbnail renderer mismatch before vs after first paint. Visible-on-load tiles still appear to come from more than one startup process. The requirement is one isolated, deterministic thumbnail renderer called for every panel the same way, with frozen grid parameters.
2. Grid layout thrashing. Logs still show multiple layout passes with tileCount=0, then a solve at 9 tiles / 3 columns, then immediately 9 tiles / 2 columns, followed by repeated no-op solves.
3. Unexpected tile count mutation. After startup the wall mutates from 9 tiles to 12 after a permissions error. This should never happen unless a real playlist reload occurs.
4. Build/version truth still stale. Recent logs still reported v19 in the session header even when later files were opened.
5. Display logging truth. The user is on a 4K display and does not want the app to mentally reduce reality to 1280 CSS pixels. Logs must distinguish browser CSS space, physical-equivalent display space, and output/render target space.
6. Thumbnail upload needs confirmation/fix. At one point the user reported being unable to upload their own thumbnail. This remains on the checklist.

3. Canonical Engineering Rules Established in Session

• Viewport-First Rendering: every tile fully or partially visible in the viewport must render immediately on startup.
• Single Layout Algorithm: one canonical wall/grid solve path; same algorithm everywhere.
• Single Export Pipeline: one export renderer, not parallel competing paths.
• Deterministic Grid Geometry: never compute layout until required wall-level inputs are known; never recompute unless wall-level inputs actually change.
• Frozen Render Context: once controls, viewport, safe area, aspect/fit, and tile count are known, the grid geometry should freeze; later thumbnail/QR loads may update tile interiors only.
• Always-On In-Memory Logging: visible, searchable, downloadable, reset on refresh.
• Language System: all UI language variants live in the single application document; must support both LTR and RTL.
• Educational Code Commentary: paragraph-level explanations at subsystem boundaries.

4. Logging Rules to Preserve

• The first log block should be canonical and ordered: Session, Build, Platform, Locale, Display, Device, Controls.
• Browser locale and app-selected interface language should be logged separately.
• Screen logging should distinguish physical-equivalent 4K truth from CSS/browser coordinates.
• Wall-ready summary should appear only after URLs are parsed and the wall exists: parsed URL count, visible tile count, columns, rows, tile size, margins.
• Layout logs should state the trigger reason and should not thrash.

5. Immediate Next Build Target

The next real target is not broad cleanup. It is a tight renderer isolation pass.

1. Block all wall solves until required wall-level inputs are valid.
2. Parse playlist and lock expected tile count once.
3. Build wall once.
4. Solve grid geometry once from control state + viewport + safe area + tile count.
5. Freeze shared render context.
6. Call the exact same thumbnail renderer for every visible tile before and after first paint.
7. Allow late thumbnail/QR/image loads to repaint only tile interiors, never wall geometry.
8. Log any unexpected tile-count mutation as an error.

6. Documentation State

• Docs package in this handoff: canonical-docs-2026-03-12-v14.zip
• Important caution: a previous attempt incorrectly replaced vision_en.html. The real uploaded vision_en.html is included here and must be preserved, then extended logically rather than rewritten wholesale.
• The next docs update should merge the new ethical/transparency/global-access ideas into the existing Vision structure, not replace it.

7. Included Files in This Package

8. Human Context Worth Preserving

There was also significant real-world pain/fatigue context during this session. Keep tomorrow’s work tight, concrete, and useful.
