# 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

- [x] 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).

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

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

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

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

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

- [x] 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)

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

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

- [x] 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

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

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

- [x] 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.

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

- [x] O10a Heads at scale (first part of O10): `State::maximal` compared every pair of heads (quadratic; about 1.5 s per call at 4 500 heads, called three times per commit); now one walk. Commit reuses the snapshot's base state instead of loading it again.

- [x] O10b Parallel snapshot work: rendering the base state's files, building file graphs from a checkpoint, and reading working-copy files now run on every core (rayon).

- [ ] O10c Snapshot without the whole base (rest of O10): load only the file graphs a snapshot needs (a checkpoint split per file or indexed), skip reading and rendering files whose stat matches a manifest written for the same base, cache materialized states. Needs a spec change to the checkpoint format; target spec §25.

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

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

- [x] 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.

## Log

- 2026-09-28 H1 done: signed-in dashboard at `/` (review queue, own proposals, assigned issues, repositories, activity feed filtered to visible repositories); test `dashboard_shows_what_needs_the_viewer`; deployed to Earth.

- 2026-09-28 O1 done: `crates/oxy-core/tests/commutativity.rs` (proptest, 32 cases): diverging clones with random edits, rebuilt in shuffled and random dependency orders, checkpoint round trip, and push in random order to a fresh clone; all give identical checkpoints, heads and trees. About 80% of generated cases conflict. No defects found. Workspace tests all green (oxy-core 129 + new).

- 2026-09-28 H2 done: empty repositories show a quickstart (remote named after the host, e.g. `earth`; CA download and `remote.X.ca` when self-signed; token placeholder; push; start from nothing; `oxy git import`); readers get a plain notice. Tests: `empty_repository_shows_a_quickstart` and a remote-naming unit test; hub spec §6 row updated; deployed.

- 2026-09-28 O2 done: `oxy fsck [--json]` (objects, op log through all parents, references and change closure with identities/blobs/chunks/signatures, bookmark states, checkpoints re-derived, ref and tag attestations verified); spec Draft 0.8h §21.1, guide updated. Test `fsck_passes_a_sound_repository_and_names_each_fault` (corrupt object, missing change, missing blob, broken op head). Clean on oxygen, oxygenhub, oxygen-vscode, oxygenhub-vscode, hellooxy. Release binary rebuilt.

- 2026-09-28 V1 done: hub API `GET /proposals/{n}/files` and `/proposals/{n}/content/{base|head}/{path}`, and anchored comments now carry their current `line` (deployed). oxygenhub-vscode 0.2.0: proposals expand to files, native diff editor per file, View Changes multi-diff, review threads on the projected side; installed in Default and Rust profiles (Developer: Reload Window to pick it up). Tests: hub api test extended; extension pass 6 fail 0 against a real hub.

- 2026-09-28 O3 done: new `oxy_core::durable` (unique temp, fsync, rename, directory fsync) for every durable write; **real bug fixed**: inside a write batch the op head moved before the batch (including the new op object) was on disk, so a crash there left an unopenable repository; `Store::flush` now runs before the head moves. Test stops commit (20 steps) and push (32 steps) at every step: both repos open, fsck clean, command retries. Spec §13.6. Hub rebuilt and redeployed with the fix. Not covered: working-copy file writes during checkout are still plain writes (user files, recoverable by snapshot).

- 2026-09-28 H3 done: header theme switch (dark/light/auto) and Settings → Appearance, theme cookie; auto follows the system live. Light-mode pass by headless Chrome screenshots of dashboard, overview, file, proposal, issue, settings, changes: found and fixed highlighted code drawing boxes in both themes (syntect scope `comment` colliding with the page `.comment` class; classes now `sy-` prefixed) and the band ADMIN link unreadable in light. Test `theme_is_chosen_in_settings_and_remembered_in_a_cookie`; hub spec §6.1; deployed. The code editor picks its theme at load, not live.

- 2026-09-28 O4 done: harness `crates/oxy-core/tests/bench.rs` (ignored; run by hand) and `docs/benchmarks.md`. Full run on disk took 5 h 14 min. **Andy: status and commit are slow at scale**: at 10 000 files / 5 000 changes a commit averages 3.8 s, a 10-file commit 9.1 s, a clean status 3.0 s, blame 2.9 s, peak memory 1.4 GiB; push 0.8 s, clone 3.4 s, log 0.4 s are fine. Cause: every snapshot loads and materializes the whole base state. New item O10 (moved ahead of O5) fixes it.

- 2026-09-28 V2 done: hub API `GET /notifications`, `POST /notifications/{id}/read`, `POST /notifications/read` (scope user:read; deployed). oxygenhub-vscode 0.3.0: status-bar bell with unread count across hubs, new-notification messages, Open Inbox quick pick that marks read and opens proposals/issues in the editor. Installed in both profiles (Reload Window). Tests: hub api test extended; extension pass 7 fail 0.

- 2026-09-28 O10a done: `State::maximal` was quadratic in heads (4 500 heads in the benchmark); now one walk, with a property test against the old definition. Commit reuses the snapshot's base. At 10 000 files / 5 000 changes: commit 3.8 s to 0.86 s, 10-file commit 9.1 s to 0.86 s, status 3.0 s to 0.80 s, blame 2.9 s to 0.81 s, memory 1.4 to 1.1 GiB; benchmark run 5 h 14 min to 1 h 12 min. Hub redeployed with it. O10b (manifest fast path, lazy base) remains for the per-file cost.

- 2026-09-28 V3 done: oxygenhub-vscode 0.4.0: `#` and `@` completion in the Oxygen commit box and comment editors, hover on `#N`; repository from the SCM root. Parsing tested in Node (pass 10, fail 0). Installed in both profiles.

- 2026-09-28 O10b done: rayon for materialize, checkpoint file graphs and working-copy reads. At 10 000 files: clean status about 800 to 460-580 ms, commit 861 to 550-605 ms. Remaining cost is loading the whole base (O10c, needs a checkpoint format change in the spec, so left for Andy to agree). Hub redeployed.

- 2026-09-28 H4 done: `/{owner}` profile (identicon, display name, bio, location, website, keys, organisations, visible repositories, activity by that person; never the email) and organisation page (description, members and roles, teams with sizes, repositories, activity); `/avatar/{name}` identicons also in the header and feeds; migration 0008 (bio, website, location) and Settings fields (http(s) websites only); `avatar` and `help` reserved. Test `profile_and_organisation_pages`; screenshot checked; deployed (andymccall profile 200 on Earth).

- 2026-09-28 O5 done. **Real bug fixed**: concurrent commands overwrote `.oxy/ops/head`, so the loser's operation (and its commit on the bookmark) vanished; a two-workspace test lost about half its commits every run. The head now moves by compare-and-swap under a short `.oxy/ops/lock`, and a mover that lost the race records a merge op (two parents, three-way merged view; bookmarks keep both sides' heads), as spec §12.1 described; undo refuses on a moved head. Tests: concurrent two-workspace commits with pushes lose nothing (5/5 runs), deterministic merge of two ops from one parent; two real oxy processes x 25 commits keep all 50 (39 merges). Spec §12.1 updated. Hub redeployed.

- 2026-09-28 H5 done: word-level marks within paired changed lines, `?w=1` hides whitespace-only changes (change, compare, proposal files), collapsible files (over 400 rows start closed), unified/split toggle remembered in a `diff` cookie, collapse/expand all. Tests: two renderer unit tests and `diffs_mark_words_hide_whitespace_and_collapse`; split view checked by screenshot; hub spec §6.8.1; deployed.

- 2026-09-28 O6 done: `oxy doctor [--offline] [--json]` (op log and stale locks, identity object/secret/expiry, author defaults, each remote: plain HTTP, token, CA file, reachability and repository id) with a next step per problem; every failed remote request now carries a hint (untrusted certificate, 401, 403, 404, refused, DNS, timeout) and transport errors no longer repeat the URL; clearer messages for different-repository remotes, pull-first pushes (still contains "pull first", which oxygen-vscode matches), unauthorized keys, and no repository. Tests: hint table and doctor scenarios. Clean on oxygen and oxygenhub checkouts. Spec §21.2, guide. Hub redeployed.

- 2026-09-28 H6 done: fork button and form, `Repos::fork` (new id, hard-linked objects, bookmarks copied, no policy), migration 0009 `forked_from`, forks list, "forked from" and fork count on the overview, "propose to upstream" link. Test `fork_and_propose_upstream` (fork, fsck, clone the fork, push a bookmark, propose upstream, files tab shows it). Hub spec §6.3 row; deployed.

- 2026-09-28 O7 done: `oxy completions SHELL` (clap_complete) and `oxy man [--dir]` (clap_mangen 0.3, 104 pages); help text written for 112 bare commands and arguments with a test that every one has help; oh-my-bash plugin loads bash completions; guide section. Tests `cli_docs` (every shell, pages, argument help on the page). Andy: `oxy completions bash > ~/.local/share/bash-completion/completions/oxy` to enable.

- 2026-09-28 O7 note: the O7 commit went in before clippy finished (two lints in the new help test); fixed in the next commit. The gate now runs to completion before every commit.

- 2026-09-28 H7 done: stars (toggle, counts), watcher counts on the overview, repository topics in settings (validated) shown as chips, Explore filter by text and topic and sort by activity/stars/name with per-row stars and topics; migration 0010. Tests: topic parsing unit test and `stars_topics_and_explore`. Gate fully green before commit; deployed.
