[Frontend] Paper triage-edit residuals from PR #1995's Codex round: mobile action stacking, Triaged-row edit, filter-change draft, stalled-detail Cancel

[Chris0Jeky]

Codex P2s on PR #1995's pre-fix head, minus the two already fixed there (sibling-edit gate, busy-slot Save). Tracked at the round ceiling.

• Phone layout: the row's third action (Edit) joins a grid that doesn't stack — verify/fix the narrow-width arrangement.
• Triaged captures are editable server-side (New|Failed|Triaged) but the Paper gate stops at New|Failed — an edit could re-open the 'nothing to propose' dead end (fix(frontend): #1944 capture triage states why a blocked action is off and what a decision did #1952 family; deliberate for now, recorded in the PR).
• Switching the Inbox board filter while an editor is open: decide draft fate explicitly (currently follows the leave-list close path).
• A stalled detail GET leaves the loading branch with no Cancel/Close.

Refs: PR #1995, #1951, #1952, tracker #1947.

[Codex lane claim v2]
lane: alpha-product-trust
issue: #1999
base: 051fb02
residual acceptance: while an archived Paper Inbox detail GET is unresolved, expose an explicit Close control that collapses the loading panel, restores focus to that row's detail trigger, leaves the request non-destructively in flight, and prevents its late result from reopening the panel; regress this behavior
owned paths/modules: frontend/taskdeck-web/src/views/paper/inbox/PaperTriageTable.vue; frontend/taskdeck-web/src/views/paper/PaperInboxView.vue; their focused existing Paper Inbox and triage-table specs only
shared-path leases: PaperTriageTable.vue; PaperInboxView.vue; focused tests for this loading-close behavior
parallel-safe work: none needed; #2423 merged and its PaperReviewView lease is released; open #2421 is parked on captureStore only
open PRs/branches/review threads checked: PR #1995 is merged; #1999 has no current claim, branch, linked delivery, or comments; open PRs #2397, #2406, #2408, #2412, #2416, #2421, and docs-only #2424 do not own these paths
human or decision gates: none for this narrow Close behavior; triaged-row edit and filter-change draft fate remain separate product decisions
status: active

[Codex lane release v2]
lane: alpha-product-trust
issue: #1999
PR: #2426
exact head: d1d786b
result: review
shipped outcome: not merged; the ready candidate gives an unresolved archived-detail load an explicit localized Hide action, collapses the panel without cancelling the read, restores focus to the row disclosure, and rejects a late payload while closed; red-first regression plus 127 focused tests, scoped ESLint, typecheck/build, and diff check pass
remaining residual: exact-head hosted CI, automatic connector outcome, and post-push age floor; #1999 remains open after this PR for triaged-edit and filter-draft decisions, plus the tracked P2 same-item close/reopen request-generation race
released paths/leases: none until PR disposition; PaperTriageTable.vue and its focused Paper Inbox test remain leased to #2426
next dependency now unblocked: none

CLAUDE_SYNC_PACKET
canonical truth changes: none; open docs-only PR #2424 retains the canonical STATUS and TESTING lease
issue/project changes: #1999 and #2426 are Review / Priority II; no closing link is used
architecture/decision impact: none
manual validation still needed: no manual browser or screen-reader run; no reusable archived-detail E2E interception fixture exists, so the attached-DOM controlled-promise regression is the deterministic proof
human actions: none
