Summary

Three small follow-ups to the session-tag feature:

• Clicking blank space beside a session's tags opens/selects that session, without changing tag-button behavior.
• Filter-option hover paint reaches the right edge instead of leaving a reserved scrollbar strip.
• New in the Sessions header carries all active filter tags through the normal folder picker. Tags are validated and saved in the initial creation transaction, not a follow-up patch. Invalid/over-limit tags create no partial session.

Existing no-filter creation, folder/worktree options, row actions, modifier selection and mobile hold actions are preserved. Unrelated text or Archived constraints can still hide a new session.

This PR targets jeroendee/pi-pocket:main for inspection. It contains only the polish commit; it does not update upstream PR #118 or its source branch.

Placement

Core under C2/C5: this corrects existing native session-list interactions and stores initial shared metadata through the existing authorized creation path. No new extension, setting, document kind or migration.

Proof

Revision: 7a264a3de67f3f2a69d1d9dc56c94d9477f4698e (one commit above the feature already merged into fork main). Real local PocketApp, HTTP routes and browser assets, isolated synthetic data, scripted model; Chromium desktop and phone-size emulation. No mocked application behavior or live session data.

Scenario	Expected → observed	Evidence
Blank tag-row area	Opens the intended session at 1280/390/320px; Ctrl-click selects; tag chips still filter/select independently	Real pointer regressions and native demo/screenshots below
Existing hold/actions	Hold opens native actions, release does not navigate, dismissal restores row-button focus; existing hover/action hit targets remain safe	New hold/focus tests plus existing tag UI suite
Filter hover	Right edge belongs to the option, with no idle gutter	Before: measured 10px gap. After: below 1px, real hovered option owns the right-edge point; screenshot below
Filtered New	Select 2 tags → Done → header New → folder picker Open → new session appears with both tags	Native desktop/390×844/320×500 journeys, actual creation request and stored metadata assertions, screenshots/demo below
Persistence/defaults	Reload retains inherited tags; no-filter New stays untagged; restart retains stored tags	UI reload tests and real-storage reopen regression
Failure boundary	All 11 active tags reach validation; 409 reports the limit, leaves the picker usable and filters intact, creates no session and makes no tag-patch request	Native UI regressions at all 3 sizes plus backend input/permission tests

The 22-second native demo below shows all 3 interactions. It samples real browser screenshots at 5fps and encodes at 10fps; no application behavior is simulated.

API example, commands and observed results

The existing POST /api/sessions request adds optional tags: string[]; cwd, title and worktree retain their existing meaning. Response shape stays { id: number }. The demo's actual creation returned HTTP 200 and opened session 29; its server metadata and visible row both contained polish and review.

Equivalent call for that isolated fixture (temporary server now stopped):

curl -X POST http://127.0.0.1:38617/api/sessions \
  -H 'Authorization: Bearer <fixture-token>' \
  -H 'X-Pocket: 1' -H 'Content-Type: application/json' \
  -d '{"cwd":"/tmp/pi-pocket-test-sL32vU/work","tags":["polish","review"]}'
# HTTP 200; response shape: {"id":29}

The displayed command is an equivalent example, not a separately executed curl call; the native UI issued the demonstrated request. Initial names are normalized with the existing rules. Over 10 canonical tags returns 409; malformed tags return 400. Viewer/scoped creation and missing X-Pocket remain 403. Tests verify no session is created on rejection.

npm run format, npm run lint, npm run check, web-module syntax checks and git diff --check pass.

The complete npm test run passed on the byte-identical candidate immediately before commit; the 12 changed-file hashes were verified against the committed files. An earlier tool-limited invocation stopped after 300 seconds; the completed background run is the result reported here:

ℹ tests 439
ℹ pass 439
ℹ fail 0
ℹ cancelled 0
ℹ skipped 0
ℹ todo 0
ℹ duration_ms 649702.219278

After commit, npm run check, npm run lint and all 17 new regressions were rerun on this exact revision:

node --test test/session-tag-creation.test.ts \
  test/session-tag-creation-ui.test.ts \
  test/session-tags-polish-ui.test.ts

ℹ tests 17
ℹ pass 17
ℹ fail 0
ℹ skipped 0
ℹ duration_ms 101365.249157

Before repair, the new regressions reproduced non-opening blank space, failed Ctrl-selection, the 10px hover gap, missing inherited/persistent initial tags and invalid initial tags wrongly accepted. The same relevant assertions now pass. Existing atomic tag, worktree and tag/filter UI tests also pass.

Limits: local integration evidence, not CI or production rollout. Mobile input is Chromium emulation; physical devices, other engines and screen readers were not audited. No live app, existing preview or upstream PR was changed. The short video is a demonstration; the tests establish the failure boundaries and persistence checks beyond what the video shows.
