Overnight backlog 2: hub usability, VS Code features, oxy stability 75036530b621

# Overnight backlog 2 (2026-09-28 to 2026-09-30)

Andy's brief: usability and features on Oxygenhub, as many features as

possible in the VS Code extensions, and a stable, mature `oxy` client.

Work top to bottom, but interleave the three tracks: after each hub or

extension item, take the next oxy stability item if one is open. Each

item is done when its tests pass, the gate is clean, it is committed with

`oxy` as Andy and pushed to Earth. Log each iteration at the bottom.

## Hub (oxygenhub): usability and features

- [ ] H1 Dashboard for signed-in users: my repositories, proposals needing me, issues assigned to me, recent activity across repositories I can see (pushes, proposals, issues, releases).

- [ ] H2 Empty-repository quickstart: exact commands for this repository (remote add, token, CA download, push) and for starting from nothing.

- [ ] H3 Theme switch (dark, light, auto) in the header and under Settings, remembered in the cookie; check every page in light mode.

- [ ] H4 Profile and organisation pages: generated identicon avatar, display name, bio, linked keys, repositories, recent activity, organisation members and teams.

- [ ] H5 Diff view: split (side by side) toggle remembered per user, collapse per file, hide whitespace changes, intra-line word highlighting.

- [ ] H6 Forks: fork button, fork creation (store copy, forked_from), fork list, "propose to upstream" from a fork.

- [ ] H7 Stars and watch counts, explore sorting (activity, stars, name) and filtering, repository topics.

- [ ] H8 Proposal and issue lists: filters (author, label, target, assignee), sort orders, pagination, counts in tabs.

- [ ] H9 File view: file tree sidebar, `y` for a permalink to the state, line range copy, blame age shading and "blame the state before this change".

- [ ] H10 Compare page with bookmark and tag pickers and a "propose this" button.

- [ ] H11 Help pages: getting started (install oxy, clone, push, tokens, CA, delegating to the hub), keyboard shortcuts, glossary for people coming from GitHub.

- [ ] H12 Password reset and email verification (email when SMTP is set; admin-issued reset link otherwise).

- [ ] H13 Notifications: per-thread mark read, filter by kind and repository, "participating" versus "watching".

- [ ] H14 Accessibility and mobile pass: focus styles, skip link, landmarks, responsive tables and tabs, contrast in both themes.

- [ ] H15 Organisation webhooks page; admin storage and repository maintenance page (sizes, oxy gc).

- [ ] H16 Performance: cache rendered Markdown and highlighted files by object hash; measure the heaviest pages on Earth before and after.

## VS Code (oxygen-vscode, oxygenhub-vscode)

- [ ] V1 oxygenhub-vscode: proposal files in native diff editors (target state against projected state through a content provider), with review threads in them.

- [ ] V2 oxygenhub-vscode: notifications count in the status bar and an inbox quick pick that opens the item.

- [ ] V3 oxygenhub-vscode: completion of `#N` and `@user` in the Oxygen commit box and in comments; hover on `#N` shows the title.

- [ ] V4 oxygenhub-vscode: create an issue from the editor selection or a TODO line, with a permalink.

- [ ] V5 oxygenhub-vscode: releases view; draft a release from a tag.

- [ ] V6 oxygen-vscode: history graph actions for split, squash and rebase (oxy history commands), with confirmation and undo hint.

- [ ] V7 oxygen-vscode: commit box polish: amend toggle, message history, signed/unsigned indicator, warning on conflict markers.

- [ ] V8 oxygen-vscode: Open on Remote in editor gutter context (line permalinks), copy permalink.

- [ ] V9 Both: README screenshots-free walkthroughs, settings documentation, CHANGELOG per release.

## oxy: stability and maturity

- [ ] O1 Property tests (proptest) that applying the same changes in any order gives the same state, over random edit sequences on several files.

- [ ] O2 `oxy fsck`: verify every object's hash, every change's references and signatures, the op log chain, and report precisely.

- [ ] O3 Crash safety audit: every write goes through write_atomic or the store's batch; a test that interrupts commit and push at each step and proves the repository still opens and fscks.

- [ ] O4 Benchmarks with thresholds: 10 000 files, 5 000 changes; status, commit, log, blame, push, clone; record numbers in docs.

- [ ] O5 Concurrency: two processes committing, snapshotting and pushing on one repository; locks hold, nothing is lost.

- [ ] O6 Error messages audit: every user-facing error says what to do next; `oxy doctor` checks identity, config, remotes, CA files, hub reachability.

- [ ] O7 Shell completions (`oxy completions bash|zsh|fish`) and man pages generated from clap.

- [ ] O8 Git round trip on real history: import a scratch mirror of tetriblox (never the live repo), export it back, compare trees at every commit.

- [ ] O9 Portability review for macOS and Windows: path separators, executable bits, case-insensitive file systems, CRLF; tests where it can be exercised on Linux.
