Branch feat/mobile-compose-keyboard from main fd7e525df; planning commit e55a06a09 (Steps 1–3 moved into this folder, standard navigation added, ledger and source-record paths repaired, plan index entry). No debug log existed for this feature before Step 4.
Step 4 entry checkpoint
2026-11-03: the user responded "approved step 3". The Step 2 and Step 3 artifacts had recorded that a separate Step 2 approval was not recovered from the imported thread; this Step 3 approval by the maintainer is taken as approval of the plan chain as revised (v1.1), including the Q1–Q3 defaults (collapsed tools hide while docked; title stays; paned dialog gets the order only).
Whole-cycle projection 0.40 reaffirmed for scope v1.1 before implementation. Rater: Claude (claude-fable-5-1), single exposed rater: saw the historical 0.40 Step 2/3 ratings and the stage projections, and inspected
composer.php,compose.css,reply_viewport.jsand the reply viewport tests before rating. This is a new dated rating by a different model from the historical rater, not an independent one. R1 three hashes verified 2026-11-03; P2; original baseline63f0849691902e665506ad4f23f374353a32ae78retained, implementation fromfd7e525df.Stage originals copied from Step 3 (not new ratings): S1 0.08, S2 0.15, S3 0.12, S4 0.07; not additive.
Pending ledger update: the ledger's cycle section (uncommitted, recovered from a conflicting stash on 2026-11-03 by keeping both sides) needs this entry checkpoint; it belongs in the closeout commit, not the planning commit.
Enhancement requests
Request: Word 97 / Midnight phone overflow and Sticker / Arena Post padding at 375px (from the original report). Disposition and reason: separate work; different cause (theme chrome, not the keyboard). Approval status: pending. Follow-up: separate cycle on request; see Step 1.
Stage 1 - Order and phone-friendly flow
Original estimate: 0.08 Retrospective stage work: 0.08
Changes:
templates/partials/composer.php: the full composer renders the tools row (tags, event) after.compose-form-actions; compact and reply composers are unchanged. The paned new-thread dialog, which renders the same full form, gets the new order too (Q3 default).public/assets/compose.css: the reserved hidden image-picker footprint on.compose-pagenow applies only from 640px up; under 640px the dedicated page's body textarea is 7.5rem high (minimum 5.5rem) instead of the seven-row default.tests/LocalAppSmokeTest.php: the rendered/compose/threadpage has Title before body, body before the Post row, and the Post row before the tools; the board's compact form has no tools row.tests/browser/composers.mjs: the order assertion is now Title, body, Post, then tools.
Verification:
Baseline captured before any change on
e55a06a09(Chromium, 375 x 667 and 375 x 300, all 16 explicit themes; the site-specificchouse,qdbandmitrapclubthemes fall back to the default on this site, so 13 distinct renderings): Post 291–330px below the top of the body, 46px of tools plus 8px of hidden picker between them; no horizontal overflow in any theme; document height 652–713px at 375 x 300.After (Chromium and WebKit, same matrix): Post 142–151px below the top of the body in every theme (tools below Post, picker footprint gone, body 120px); still no horizontal overflow anywhere; document height 565–598px at 375 x 300. WebKit and Chromium agree within 1px.
php tests/run.php LocalAppSmokeTest: 157/160. The three failures (testPrivateLobbyOnlyExposesLobbyAccountAndAuthenticationSurfaces,testPrivateForteRoutesRecoverExpiredSessionsInsteadOfReturningFalseNotFound,testRepositoryArchiveDownloadFilenamesIncludeReadableTimestamp) are the same three recorded as pre-existing in the ui_tools_launcher and deployment_config summaries.node tests/browser/composers.mjs: passed (New post with Title and tags, first line as title, menu wording, reply page, missing parent, both pages without JavaScript).node tests/browser/compose_disclosure.mjs: passed.node tests/browser/compose_layout_stability.mjs: failed before and after at the firstwaitForLoadState('networkidle')(line 86) in this environment; reproduced identically on the untouched planning commit in a scratch worktree, so it is not attributable to this stage. A 12-second request log of/compose/threadwithout the test's identity fixture shows no repeating requests; the cause is in the test's signed-identity path and is left for Stage 3, where that test is run again.Desktop paned new-thread dialog (
/forteat 1280 x 800, Chromium): Title, body, Post row, then tags; dialog 448 x 371px before and after; no overflow, no page errors; screenshot reviewed.Existing theme defects: none found that block composer use (no horizontal overflow at 375px in any theme on this page). The Word 97 / Midnight / Sticker / Arena report stays under Enhancement requests.
Notes:
Risk check from the plan: dropping the phone footprint cannot reintroduce the eligibility shift, because
image_upload.jsonly un-hides.image-compose-fieldsonce an image is attached (or an input notice exists), never on eligibility alone.Playwright's WebKit binary was not installed in this environment; it was installed into the user cache (
~/.cache/ms-playwright/webkit-2248) for the pinnedplaywright-core1.58.1. No repository dependency changed.Stage 1 alone does not keep Post visible with a 300px visible height (Post bottom is ~415px from the top of the page); that is Stage 2's docking.
Estimate details: original scope as planned; no revision. Retrospective unchanged: the template and CSS work were as expected; the pre-existing test failure and the missing WebKit binary cost investigation time but are not this stage's scope.
Merge note (2026-11-03):
mainalready carried the compose_keyboard_fit cycle (Step 3 approved 2026-11-02, merged), which fixes the same report with CSS only and orders the full composer body, Post, Title, tools with a 5.5rem phone body. The user chose to keep that order, so this stage's template, stylesheet and order-assertion changes were dropped in the merge in favour ofmain's; only this cycle's plans and summary were merged. Stage 1's commit331399d05remains on the branch as history. This cycle continues as the keyboard-docking follow-up that compose_keyboard_fit's Step 1 anticipated (its Option B); Steps 2–3 need a recorded revision for the Title position before Stage 2.
