# Overnight backlog 2 (2026-09-28 to 2026-09-30)
2
3
Andy's brief: usability and features on Oxygenhub, as many features as
4
possible in the VS Code extensions, and a stable, mature `oxy` client.
5
Work top to bottom, but interleave the three tracks: after each hub or
6
extension item, take the next oxy stability item if one is open. Each
7
item is done when its tests pass, the gate is clean, it is committed with
8
`oxy` as Andy and pushed to Earth. Log each iteration at the bottom.

## Hub (oxygenhub): usability and features
11
c8f92cc5 Andy McCall ↶ 12
- [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).
5140e604 Andy McCall ↶ 13
- [x] H2 Empty-repository quickstart: exact commands for this repository (remote add, token, CA download, push) and for starting from nothing.
1a16fa09 Andy McCall ↶ 14
- [x] H3 Theme switch (dark, light, auto) in the header and under Settings, remembered in the cookie; check every page in light mode.
57f8f0b3 Andy McCall ↶ 15
- [x] H4 Profile and organisation pages: generated identicon avatar, display name, bio, linked keys, repositories, recent activity, organisation members and teams.
e701ec42 Andy McCall ↶ 16
- [x] H5 Diff view: split (side by side) toggle remembered per user, collapse per file, hide whitespace changes, intra-line word highlighting.
eaa9bd54 Andy McCall ↶ 17

35
## VS Code (oxygen-vscode, oxygenhub-vscode)
36
b38ece2c Andy McCall ↶ 37

75036530 Andy McCall ↶ 46
47
## oxy: stability and maturity
48
123ba31b Andy McCall ↶ 49
- [x] O1 Property tests (proptest) that applying the same changes in any order gives the same state, over random edit sequences on several files.
fd16934c Andy McCall ↶ 50
- [x] O2 `oxy fsck`: verify every object's hash, every change's references and signatures, the op log chain, and report precisely.
cc9ba05a Andy McCall ↶ 51
- [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.
13a0f400 Andy McCall ↶ 52
- [x] O4 Benchmarks with thresholds: 10 000 files, 5 000 changes; status, commit, log, blame, push, clone; record numbers in docs.
07eb99be Andy McCall ↶ 53
- [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.
e7ddd552 Andy McCall ↶ 54
- [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).
540b2292 Andy McCall ↶ 55
- [x] O12 `log_for_path_in` and `blame_in` rebuild and re-render the whole state on every call, and walk every change: take an already loaded state, stop at the first change touching the path when only the newest is wanted, and benchmark it (found in H16).
e1dc6d6a Andy McCall ↶ 56
- [x] O10c Snapshot cost in the in-memory state: faster graph hashing, no unused predecessor map, inline successor sets, lines moved not copied; `OXY_TIMINGS=1` phase timings.
f97d3556 Andy McCall ↶ 57
- [x] O10d Skip reading text files whose stat matches a manifest that recorded them equal to the base (racy entries, those modified at or after the manifest was written, are still read); test that no edit is ever missed.
6f16ce2b Andy McCall ↶ 58
- [x] F1a **Priority (Andy, 2026-09-28): dogfood OxygenFlow.** Every push to oxygen, oxygenhub, oxygenflow and both extensions lints, tests and builds through OxygenFlow on Earth, with results as checks on OxygenHub. F1a: ephemeral scratch mounts in jobs (`ephemeral://tmpfs`, `ephemeral://disk`) so builds have room; `make deploy-runner`.
9b761fe2 Andy McCall ↶ 59
- [x] F1b A build image for the runner: a rootfs with the Rust toolchain (stable, rustfmt, clippy), Node, e2fsprogs-free build basics, and every crate of the oxygen, oxygenhub and oxygenflow lock files vendored with cargo pointed at them (jobs have no network); a script that rebuilds it when lock files change; imported on Earth and measured on a real cargo test of oxygen in a microVM.
66eb6469 Andy McCall ↶ 60
- [x] F2 oxygen pipeline (.flow/pipeline.kdl): fmt, clippy -D warnings, tests, release build; green on a real push.
85df6b4c Andy McCall ↶ 61
- [x] F3 oxygenhub pipeline: needs oxygen alongside (path dependencies), so the job checks out oxygen at a pinned change; fmt, clippy, tests, build.
9ce6f084 Andy McCall ↶ 62
- [x] F4a oxygenflow's pipeline gains fmt, clippy and tests, with oxygen as its pinned subrepo; oxygenhub builds against the oxygen that oxygenflow pins (one oxy-core), and claims follow subrepos of subrepos.
3498fb47 Andy McCall ↶ 63
- [x] F4b Extension pipelines (oxygen-vscode, oxygenhub-vscode): typecheck, bundle, tests and package, offline. Needs the npm packages in the build image, and `oxy` for oxygen-vscode's tests (built in the job from a pinned oxygen). The hub client tests skip without a hub binary.
85df6b4c Andy McCall ↶ 64
- [ ] F6 Faster runs: the runner takes one job at a time (oxygenhub is about 14.5 min to green, 8.5 of them the release build), so run independent jobs in parallel within the runner's CPU and memory, and reuse a build tree between jobs of one run (clippy, test and build compile the same crates).
9a239f06 Andy McCall ↶ 65
- [x] F5 Required checks: each repository's default bookmark requires its pipeline's checks to land, and the work loop pushes and waits for green instead of gating only locally.
b037ade1 Andy McCall ↶ 66
- [x] O10e Checkpoint payload version 2: large file graphs as shared blobs named from an index, read and decoded in parallel; readers accept both versions (spec §11). Agreed by Andy on 2026-09-28.
c1fe1fb2 Andy McCall ↶ 67
- [x] M1 (metalgear feedback 1, reported by Andy) Bookmarks with `/` in their names could not be pushed: attestation and checkpoint files are now flat, escaped names (oxygen#12). The hub is pinned to the fix and deployed.
68
- [x] M2 Flow on/off per repository in the hub (Andy's request; feedback 10): a switch in repository settings for site admins, with hub.toml's `[flow] repos` as the default; no restart.
f8c69576 Andy McCall ↶ 69
- [x] M11 (feedback 12, Andy: urgent) Flow runs numbered per repository, not by the hub-wide id; existing runs renumbered and their check links rewritten by migration 0019 (oxygenhub#23).
2dd42fa1 Andy McCall ↶ 70
- [x] M12 (Andy; feedback 14a) Delete a bookmark on a remote: `oxy push REMOTE --delete NAME` (a signed, attested deletion the server checks like any update; never the default bookmark), and a delete button on the hub's bookmarks page for writers.
93e7f1d9 Andy McCall ↶ 71
- [x] M13 (feedback 3a) `oxy bookmark switch --carry`: take uncommitted work to the other bookmark when it applies cleanly there (and `bookmark create --switch` moving the working copy onto a new bookmark at its base, changes and all).
72
- [x] M14 (feedback 7a) `oxy show`'s summary lists every path the change touches with its kind (added, modified, removed, renamed, mode), not only additions.
85ef828b Andy McCall ↶ 73
- [x] M3 Start a run without moving a bookmark (feedback 9): "Run pipeline" on a state and "Re-run" on a finished run, in the web and the API.
ce3e73ce Andy McCall ↶ 74
- [x] M4 Guest `/dev/fd`, `/dev/stdin|stdout|stderr` links in flow-init (feedback 15), and job variables `FLOW_STATE`, `FLOW_HEADS`, `FLOW_BOOKMARK`, `FLOW_RUN`, `FLOW_REPO` (feedback 17).
73609c9f Andy McCall ↶ 75
- [x] M5 Sandbox-level `env` in pipeline.kdl, and the image's environment kept through `flow rootfs import` (feedback 16).
08b38884 Andy McCall ↶ 76
- [x] M6 Flow API: `GET /repos/{o}/{n}/flow/runs`, `/flow/runs/{n}` with jobs, a job's log; checks by head hash as well as state (feedback 11). JSON 404s under `/api/v1` (feedback 13). Per-repository run numbers, or a note (feedback 12).
c1fe1fb2 Andy McCall ↶ 77
- [ ] M7 Server push errors name the operation and bookmark and log the error chain (feedback 2).
78
- [ ] M8 `merge` updates a working copy that is clean against the pre-merge base; `checkout` tells "removed by you" from "not yet written"; `bookmark switch --help` says what happens to uncommitted work (feedback 3).
79
- [ ] M9 Small oxy items: `oxy describe` (tag, else bookmark + change, `+dirty`) and tags accepted where a change is (feedback 4); `commit -F` (6); `submodule status` shows added-but-unpinned and has `--json` (5, 7); doctor before the first commit (8).
80
- [ ] M10 Hub: say "signed by an unlinked key" on changes and in `/api/v1/user`, pointing at Settings (feedback 14).
28fee1c9 Andy McCall ↶ 81
- [ ] P1 **Conflict resolution on OxygenHub** (Andy's list, item 1). A resolver page for a conflicted state:
82
  - Per conflict region: pick a side, several sides, or none; edit freely; tree conflicts too (keep a candidate).
83
  - Commit the result as a `kind = resolution` change on the bookmark, through the web-edit path. Signing: sealed when the author next pushes, or "resolve in VS Code" hands off to oxygen-vscode.
84
  - Shareable link to a conflict.
85
  - First single-user, then P1b.
86
- [ ] P1b Real-time collaboration on the resolver: presence, live edits merged between viewers (SSE or WebSocket), and whoever is viewing sees the resolution land.
87
- [ ] P2 **Function history** (item 5; needs no semantic-deps):
88
  - oxy-core: a history query over a set of atoms (the changes that inserted or deleted any of them, with deleted atoms included).
89
  - Hub: function boundaries by tree-sitter for the languages we host (Rust, TypeScript, Python, shell).
90
  - Clicking a function on a file page shows every ChangeId that touched its lines, as a list and a small graph; exact because atoms keep identity across edits and moves.
91
  - The cross-file semantic graph stays out; noted as future work.
92
- [ ] P3 **Swimlanes** (item 3):
93
  - Hub: a bookmark's changes drawn as lanes of independent changes (oxy-core `lanes`), with dependencies as edges and no merge nodes.
94
  - P3b: drag and drop on proposal bookmarks only. Dropping a change onto another proposes a squash, dragging a dependent chain proposes a rebase. The hub produces a plan and the author's oxy or oxygen-vscode applies and signs it (V6 has split, squash and rebase). Reordering independent changes means nothing and is not offered.
95
- [ ] P4 **Signed Flow receipts**:
96
  - A `receipt` object type in the Oxygen spec.
97
  - A runner identity whose key (composite Ed25519 + ML-DSA-65) signs each receipt.
98
  - Receipts stored in the repository and verified by the hub.
99
  - Flow `output` and artifacts, so a release asset links to the receipt that built it.
100
- [ ] P4b **Trust dashboard** (item 4): per release and asset, a graph of authors' identities and signatures, the runner and its pinned environment, inputs (state, scope hash), and receipts, with a one-click audit view and export.
101
- [ ] P5 **Web workspaces** (item 2), in parts:
102
  - P5a: flow-casfs, a read-only FUSE mount of a state from CAS chunks, measured.
103
  - P5b: "Open in Workspace" on a change. openvscode-server (MIT, unmodified) with oxygen-vscode inside a Firecracker microVM per workspace, the state mounted read-only through casfs with an ephemeral overlay for edits, and commits back through oxy. Boot time measured, aiming under 100 ms for the mount.
104
  - A fork ("oxycode") only if an extension cannot do what we need; decided with Andy.
105
- [ ] P5c Import microsoft/vscode's full Git history with `oxy git import` into a local scratch repository (not published): about 130 000 commits as a stress test of import, log, blame and status at scale, recorded in docs/benchmarks.md.
3c5c6ad2 Andy McCall ↶ 106
- [x] O10f Load file graphs lazily from a version 2 checkpoint: a state keeps unread graphs by reference and reads one when first needed.
cc7a0056 Andy McCall ↶ 107
- [x] O10g Render only what a snapshot needs, first part: the manifest records, per file, the key of the base graph it matched, so an unchanged file whose graph is untouched is neither read nor rendered; used by status, log, show, tag and bookmark.
108
- [ ] O10h The same for commit, diff, amend and the other full snapshots: a lazy base that builds only the graphs the change touches; cache materialized states.
2cc29048 Andy McCall ↶ 109
- [x] O5 Concurrency: two processes committing, snapshotting and pushing on one repository; locks hold, nothing is lost.
e4cd0c54 Andy McCall ↶ 110
- [x] O6 Error messages audit: every user-facing error says what to do next; `oxy doctor` checks identity, config, remotes, CA files, hub reachability.
6e666883 Andy McCall ↶ 111
- [x] O7 Shell completions (`oxy completions bash|zsh|fish`) and man pages generated from clap.
ff7c55b5 Andy McCall ↶ 112
- [x] 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.
214a3f27 Andy McCall ↶ 113
- [x] O11 Line placement found by O8: in 5 of 539 tetriblox commits (all non-merge; e.g. 43de61fac554 src/banked/code_bank_07.c, 021ad78791a2 code_bank_03.c, 2721670b49af code_bank_02.c, 435fbe1d5fac scripts/x16_unchanged.py, d17c19b22748 test/test_memory_guards.py) one line lands elsewhere than in Git with no conflict reported, so an insertion is anchored between atoms that are not adjacent in the base. Reproduce with `oxy git verify` on a scratch mirror; find which edit of the importer's diff (build_from_entries/text_edits) anchors non-adjacently, add a debug assertion for anchor adjacency, fix, re-verify.
3ec96ad1 Andy McCall ↶ 114
- [x] 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
c8f92cc5 Andy McCall ↶ 117
118
- 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.
123ba31b Andy McCall ↶ 119
- 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).
5140e604 Andy McCall ↶ 120
- 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.
fd16934c Andy McCall ↶ 121
- 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.
b38ece2c Andy McCall ↶ 122
- 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.
cc9ba05a Andy McCall ↶ 123
- 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).
1a16fa09 Andy McCall ↶ 124
- 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.
13a0f400 Andy McCall ↶ 125
- 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.
59171dcf Andy McCall ↶ 126
- 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.
b8a03993 Andy McCall ↶ 127
- 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.
978470f7 Andy McCall ↶ 128
- 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.
0bb9413f Andy McCall ↶ 129
- 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.
57f8f0b3 Andy McCall ↶ 130
- 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).
2cc29048 Andy McCall ↶ 131
- 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.
e701ec42 Andy McCall ↶ 132
- 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.
eaa9bd54 Andy McCall ↶ 134
- 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.
6e666883 Andy McCall ↶ 135
- 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.
4941f240 Andy McCall ↶ 136
- 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.
e42e4e19 Andy McCall ↶ 137
- 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.
ff7c55b5 Andy McCall ↶ 138
- 2026-09-28 O8 done. `oxy git verify GIT_DIR` checks an import commit by commit (content, exec bits, symlinks, pins; conflicts named with their changes; first differing line). On a scratch mirror of tetriblox (539 commits, 208 merges, 880 gitlinks; the live repo was only read by `git clone --mirror`): import 36 s, tip tree round-trips exactly, and verification found **real core bugs that also affect ordinary commits**, now fixed: (1) insert after a line, then delete that line, left a delete/insert conflict (deletions now depend on the inserters of the lines right after them); (2) a binary or submodule reverted to an earlier blob lost it, and replacements had no dependency (now depend on the change that set their old blob; causal supersession, legacy records keep the old rule); (3) merges of independently replaced binaries/submodules stayed conflicted (importer resolves to the merge's blob). Mismatching commits went from 50+ (verification stopped early) to 5, now O11. Tests: 3 regressions (sequential insert/delete, binary revert, Git binary merge + verify). Spec Draft 0.8i §8.1, §9.3, §23. Hub redeployed.
a88bcedb Andy McCall ↶ 139
- 2026-09-28 H8 done: open counts on the Proposals and Issues tabs (from the repository lookup), issue `author:` filter and sorts (newest/oldest/updated/comments), proposal filter (`author:`, `label:`, `target:`, words) with labels shown and sorts (updated/newest/oldest), 25-per-page pager keeping filter and sort. Test `lists_filter_sort_page_and_count`; spec §6.3 rows; deployed.
3ec96ad1 Andy McCall ↶ 140
- 2026-09-28 O9 done: `portable::Platform` (detected, overridable in tests); no exec bits: snapshot keeps the recorded bit (it was recording a mode change on every Windows snapshot); no symlinks: a plain file holding the target stays the symlink (spec §7.7 required it, the code converted it); checkout lists case collisions and Windows-invalid names on affected platforms and `oxy doctor` does everywhere; CRLF already handled by the eol attribute; separators verified (components joined with /). Tests simulate Windows and macOS. Follow-up: normalise `\` in paths typed on Windows command lines. Spec §7.7. Hub redeployed.
f184f6d5 Andy McCall ↶ 141
- 2026-09-28 V4 done: oxygenhub-vscode 0.5.0 "New Issue from Selection" (context menu): quotes the selection under a permalink (head-pinned when single-headed and saved), TODO/FIXME lines suggest the title and can be annotated `TODO(#N)`, then the issue opens; line-range links. Tests pass 13 fail 0. Installed in both profiles.
214a3f27 Andy McCall ↶ 142
- 2026-09-28 O11 done: root cause in `text_edits`: similar's capture_diff_slices runs a Compact hook that slides deletions along equal lines and can leave an insertion with an earlier old index, anchoring a block one line early (a brace on the wrong side). Now uses the diff with only the Replace hook. Randomized replay test (2 000 repetitive files; fails on the old code). tetriblox scratch import verifies all 539 commits, 95 585 files. Note: that commit also picked up Andy's new docs/xenon_spec.md and fix.py, fix2.py, format_xenon.py from the working copy; left for Andy to decide.
143
- 2026-09-28 UI request from Andy (between items): repository page centred with the sidebar, README as wide as the file table, clone command in the top bar; repository, organisation and account settings get a sticky list of sections on the left and equal-width boxes. Screenshot-checked, deployed.
1197a869 Andy McCall ↶ 144
- 2026-09-28 V5 done: oxygenhub-vscode 0.6.0 Releases view (releases per repository with latest/pre-release, assets with size and downloads, source archives) and Draft Release…: pick an unreleased tag, title from the tag message, notes generated from the changes since the newest full release's tag, pre-release suggested from the tag name. End-to-end test tags with oxy and releases through the client. Tests pass 15 fail 0; extension spec §8.2. Installed in both profiles.
da7997cc Andy McCall ↶ 145
- 2026-09-28 H9 done: file page tree sidebar (path expanded, 200 per directory then "N more", hidden under 900 px); state addresses `h1+h2` (sorted full hashes, at most 32) so any state has a permalink; `y` on file and tree pages switches to it; a line-range bar with Copy lines and Copy permalink; blame shaded in ten age steps and each run links "blame before this change" (the state of its dependencies). Tests: view unit tests (sidebar order and limit, state addresses) and browse end to end. Hub spec §6.3, §6.6, §6.13. Deployed; health ok.
e4b40b3b Andy McCall ↶ 146
- 2026-09-28 Requests from Andy (between items):
147
  - **OxygenHub naming.** The name is written OxygenHub everywhere people read it (hub, both extensions: oxygenhub-vscode 0.6.1, oxygen-vscode 0.7.1).
148
  - **OxygenFlow M0, built and running on Earth.** Xenon was renamed to OxygenFlow, in the separate oxygenflow repository. It has:
149
    - flow-core: KDL pipeline, validation with lines, canonical CBOR, receipts, runner API types
150
    - flow-init, as the guest's PID 1
151
    - the Firecracker microVM tier
152
    - `flow check/run/rootfs/runner`
153
    - a microVM conformance test
154
  - **Hub side.** Pushes start runs, a runner API with repo-scoped read-only job tokens, jobs mirrored as `flow/<job>` checks, and a Flow tab with the SVG job graph and live logs. Hub spec §13.2; migration 0011; tests/flow.rs.
155
  - **Earth.** Firecracker v1.17.0, kernel 6.1.155 and the Alpine 3.24.2 rootfs, pinned in ~claude/flow. `flow-runner.service` is hardened. `hub.toml` gained `[flow]` limited to `andymccall/*` (backed up as hub.toml.before-flow).
156
  - **Result.** oxygenflow's own pipeline passes (runs 1 and 2). Andy's spec is committed, renamed to OxygenFlow, with a README.
157
  - **oxy-core.** `tls_client_config` is public.
e4a9dc29 Andy McCall ↶ 158
- 2026-09-28 Flow state stamps instead of CI badges (oxygenhub#1, closed by the change):
159
  - `/flow/stamp/{ref}` is an SVG of the newest run of exactly that state, with receipt hashes in its metadata. For bookmarks and tags it redirects to the stamp of the current state.
160
  - In READMEs, `[![flow](.flow/stamp)](.flow/run)` resolves against the state being viewed.
161
  - Fixed oxygenhub#2 on the way: README images pointed at the HTML file page. There is now a `/raw/{ref}/{path}` route.
162
  - The oxygenflow README shows its stamp (oxygenflow#1).
163
  - From now on every item gets an issue on Earth and its commits say closes/refs #N.
164
  - Gaps the workflow exposed became H17 to H20 (oxygenhub#3 to #6).
039b4ccb Andy McCall ↶ 165
- 2026-09-28 H10 done (oxygenhub#7, closed by the change):
166
  - The compare page has base and head pickers (bookmarks and tags in a datalist; any change or state can be typed), a swap link, `/compare?base=&head=` as the form target, and `/compare` alone comparing the newest other bookmark against the default.
167
  - **Propose this** shows for writers when both sides are bookmarks and head has changes; it becomes "proposal #N is open" when one exists.
168
  - Tests in browse and proposals. Hub spec §6.3. Deployed.
d14d7832 Andy McCall ↶ 169
- 2026-09-28 H11 done (oxygenhub#8, closed by the change):
170
  - `/help` is a sectioned page with getting started, identity and key linking, pushing, cloning, proposals, delegating to the hub, pipelines and state stamps, the keyboard, and a GitHub glossary.
171
  - Every command carries this hub's address, remote name and certificate step.
172
  - It is linked from the band, the footer and the `?` sheet.
173
  - Browse test; hub spec §6.3. Deployed.
370c7584 Andy McCall ↶ 174
- 2026-09-28 H12 done (oxygenhub#9, closed by the change). Spec §5.1.1 first.
175
  - **Account links.** 32 random bytes, stored as a BLAKE3 hash, single use and expiring. Migration 0012.
176
  - **Verification.** Sent on registration and on every address change (48 h). It only verifies the address it was sent to. Settings shows the status and can resend: one every 2 minutes per address, 10 an hour per account.
177
  - **Reset by email.** By username or verified email (1 h, one every 2 minutes). The answer is identical whether or not anything matched, and mail goes out in the background so timing leaks nothing.
178
  - **Reset by an administrator.** From /admin (24 h, shown once, audited).
179
  - **Using a reset link.** It rotates the session salt (every session ends) and voids other links. TOTP stays on; banned accounts are refused.
180
  - **Mail.** A shared `mail` module with `file://` for development. Notification mail only goes to verified addresses.
181
  - **Tests.** tests/recovery.rs covers the whole flow through a file mailbox.
182
  - **Earth.** Earth has no SMTP, so resets there go through the admin link. Existing addresses count as unverified until verified.
86394a75 Andy McCall ↶ 183
- 2026-09-28 H13 done (oxygenhub#10, closed by the change):
184
  - Notifications record their thread, repository and reason (participating or watching) and can be marked done. Migration 0013 backfills threads and repositories from the URLs.
185
  - The inbox shows one row per thread, with updates and new counts.
186
  - Filters: inbox, unread and done views, reason, kind family and repository, with counts.
187
  - Per-thread read, unread and done. Done threads return when a new event arrives.
188
  - Opening a row marks its thread read.
189
  - `notify::add` takes a struct.
190
  - Tests extended in tests/issues.rs. Hub spec §10.
191
  - The API keeps per-item read; per-thread actions in the API are a follow-up for the VS Code inbox.
192
- 2026-09-28 Andy asked for uploaded profile pictures and organisation logos: added as H13b (oxygenhub#11), taken next.
227dde3b Andy McCall ↶ 193
- 2026-09-28 H13b done (oxygenhub#11, closed by the change):
194
  - Upload a picture under Settings › Profile › Picture, or an organisation logo under its settings (owners only).
195
  - PNG, JPEG or WebP, recognised by content; at most 5 MiB and 8 000 px a side.
196
  - Every upload is decoded, centre-cropped, scaled to 400×400 and re-encoded (PNG if it has transparency, JPEG otherwise), so uploaded bytes are never served.
197
  - `/avatar/{name}` serves the picture with an ETag, falling back to the identicon; Remove restores the identicon.
198
  - Avatar CSS no longer pixelates photos.
199
  - Unit tests for processing and refusals; end-to-end test in tests/accounts.rs. Hub spec §6.3. Deployed.
200
  - This machine's disk filled up (0 bytes free) during the build. I removed the regenerable `target/debug/incremental` caches of oxygenhub and oxygen (33 GB) and build with CARGO_INCREMENTAL=0 from now on.
93036492 Andy McCall ↶ 201
- 2026-09-28 H14 done (oxygenhub#12, closed by the change):
202
  - Keyboard and screen readers: a focus ring on everything focusable; a skip link to `<main id="main">`; named landmarks (Account, Site, Repository and Settings navigation); `aria-current` on the current tab.
203
  - Contrast: WCAG AA in both themes, enforced by tests/contrast.rs over the CSS variables.
204
    - Light theme: mute, acc, ok, now and the string, function and comment syntax colours adjusted.
205
    - Dark theme: comment colour adjusted.
206
    - Text no longer uses `--dim`.
207
  - Under 760 px: tab bars scroll on one line, the tree drops its message column, wide content scrolls inside its panel, sectioned pages stack, and the header search hides.
208
  - Checked at 390 px on Earth. Hub spec §6.13.
3982115e Andy McCall ↶ 209
- 2026-09-28 H15 done (oxygenhub#13, closed by the change):
210
  - **Organisation webhooks.** A Webhooks section in organisation settings: add, ping, enable or disable, delete, deliveries and redeliver.
211
    - Repository and organisation webhooks now share one module (`web/webhooks.rs`) and one template macro.
212
    - Every action checks that the hook belongs to the scope it is managed from.
213
  - **Storage.** `/admin/storage` lists each repository's size, loose objects and packs. Maintenance runs `oxy gc` (grace period kept, write lock held) on one repository or all, and is audited.
214
  - Tested in tests/accounts.rs. Hub spec §6.3, §12.2. Deployed.
215
  - Earth's repositories can be maintained from /admin/storage now; I have not run it on Andy's data.
30924fc6 Andy McCall ↶ 216
- 2026-09-28 H16 done (oxygenhub#14, closed by the change). Measured on Earth first (oxygenhub/docs/performance.md).
217
  - The raw bytes of heavy files took 5 ms, but their pages took 196 to 428 ms: syntax highlighting, Markdown rendering, and above all the file's "last change", found by `log_for_path_in` rebuilding the state and reading every change on each view.
218
  - Now cached, in memory-bounded LRUs keyed by content or by (state, path): rendered Markdown, highlighted files, last change and blame. Labels are still computed fresh.
219
  - `?plain=1` takes the lean path.
220
  - Warm views: spec.md 196 → 8 ms, repo/mod.rs 400 → 18 ms, state.rs 317 → 14 ms, blame 428 → 23 ms.
221
  - Unit test for the LRU; browse test checks the second view hits the cache. Hub spec §16.3.
222
  - Follow-up for oxy-core: `log_for_path_in` should reuse a loaded state instead of rebuilding it.
540b2292 Andy McCall ↶ 223
- 2026-09-28 O12 done (oxygen#1, closed by the change; the first issue in the oxygen repository):
224
  - oxy-core has `log_of(state)`, `log_for_path_of(state, path, limit)` and `blame_of(state, tree, path)`. They find the path in the tree view alone, with no full render, and the walk stops at `limit`.
225
  - `log_for_path_in` and `blame_in` wrap them and load once instead of twice.
226
  - Test `history_and_blame_of_a_loaded_state_match_the_full_walk`; gate green; release binary rebuilt.
227
  - The hub uses them for last change, blame and tree rows.
228
  - Cold file pages on Earth: 196/400/317/428 ms (before any caching) → 146/256/121/88 ms; warm 8–24 ms (oxygenhub/docs/performance.md).
3b1dc8a9 Andy McCall ↶ 229
- 2026-09-28 H17 done (oxygenhub#3, closed by the change):
230
  - `POST /issues` takes labels, assignees and a milestone (triage). Unknown names are refused before anything is created.
231
  - New `PATCH /issues/{n}`: title and body for the author or triage; the whole label set, assignees and milestone for triage; each change goes on the timeline.
232
  - `POST /labels` creates or changes a label and `DELETE /labels/{name}` removes it (triage).
233
  - hub-api types `IssueEdit` and `NewLabel`; TS regenerated (the extension's copy follows with its next change). Test `api_issue_triage_and_labels`; hub spec §12.1.
234
  - Dogfooding:
235
    - Each Earth repository now has the labels bug, feature, performance, accessibility, security and gap.
236
    - Every issue so far is labelled.
237
    - The work log's issue helper sets labels from now on.
b3e60590 Andy McCall ↶ 238
- 2026-09-28 H18 done (oxygenhub#4, closed by the change):
239
  - Any bare `#N` in a pushed change's message, on any bookmark, adds "referenced by change <hash> on <bookmark>" to that issue's or proposal's timeline, with the hash linked.
240
  - `closes #N` still records only "closed by change"; `owner/name#N` from other repositories is left alone.
241
  - `refs::references` has a unit test; the issues end-to-end test covers issue and proposal timelines. Hub spec §8.
242
  - From now on, the `refs #N` lines in work commits show on the Earth issues.
b3b9c2f3 Andy McCall ↶ 243
- 2026-09-28 H19 done (oxygenhub#5, closed by the change). Spec §8.2 first.
244
  - Projects belong to a person or organisation: `/projects/{owner}` and `/projects/{owner}/{n}` ("projects" is now a reserved name).
245
  - Columns start as Backlog, Doing and Done; they can be added, renamed, moved and removed (their cards go to the first column; the last column stays).
246
  - Cards are issues or proposals of the owner's repositories (by `repo#N`, or `#N` with a repository picked) or notes. Each can be on a project only once. They move, reorder and are removed without JavaScript.
247
  - Visibility: public or private (owner, organisation members and admins). Cards from repositories the viewer cannot read are not shown at all.
248
  - A closed project is read-only; deleting one leaves the issues.
249
  - Issue and proposal pages list their projects; profiles and organisation pages link to them.
250
  - Migration 0015. Test `project_boards` plus reference parsing. Screenshot-checked on a scratch hub.
251
  - The screenshot tool now disables the browser cache (an earlier shot had served a stale style.css).
252
  - Gap found: no projects API → H21 (oxygenhub#15).
d3a6a9b3 Andy McCall ↶ 253
- 2026-09-28 H20 done (oxygenhub#6, closed by the change): relative links and images in issue, comment and proposal Markdown resolve against the repository's default bookmark; release notes resolve against the release's tag. Test `issue_markdown_follows_the_default_bookmark`.
254
- 2026-09-28 Webhooks, from Andy's report (oxygenhub#16 and #17, closed by the change):
255
  - **Why Discord got nothing.** Every delivery, ping included, was the OxygenHub envelope, which Discord rejects ("Cannot send an empty message").
256
  - **Formats.** Hooks now have a format: `oxygenhub`, `discord` (an embed with the event's summary; mentions disabled so user text cannot ping) or `slack`. It is picked from the URL; migration 0016 switched existing Discord and Slack hooks.
257
  - **Settings.**
258
    - The URL is masked (long path segments and query cut short, since chat webhooks keep a token there; the audit log records the same masked form) and wraps inside the panel.
259
    - The table shows the last delivery result.
260
    - Each hook has an edit form; a blank URL or secret keeps the current one.
261
  - **Also found.** Issues opened, commented on, closed or reopened in the web interface emitted no webhook events at all; now they do.
262
  - **Tests.** Unit tests for the formats and masking; end-to-end test `webhook_formats_editing_and_web_issue_events`. Hub spec §12.2.
17af6ca5 Andy McCall ↶ 263
- 2026-09-28 H21 done (oxygenhub#15, closed by the change):
264
  - `/api/v1/projects/{owner}`: list and create.
265
  - `/api/v1/projects/{owner}/{n}`: the board as the caller may see it, and `PATCH`.
266
  - `/cards`: add a reference or note; columns by id or name.
267
  - `/cards/{id}`: move or remove.
268
  - The pages and the API share `rights_of`, `board_columns` and `add_card`. hub-api types added; TS regenerated. Test `api_projects`. Hub spec §12.1.
e5e73109 Andy McCall ↶ 269
- 2026-09-28 Repository overview, from Andy's review (oxygenhub#18, closed by the change):
270
  - The heads and conflicts strips sit inside the main column.
271
  - Clone is a button beside search: a popup with a selectable command, copy, and the bare URL.
272
  - Contributors box: authors counted from the state's changes, linked to hub accounts through linked keys; unsigned changes with no author show as "Unattributed changes".
273
  - Languages box: bytes per language (an extension table plus syntect), with Linguist's colours. Prose, lock files and vendored paths are left out; under 1% folds into Other.
274
  - A public, internal or private badge by the repository name.
275
  - Tests in browse.rs and a unit test for detection. Screenshot-checked on Earth.
276
  - Andy's key is not linked to his account yet (Settings › Keys), so his contributor entry is not a link.
5d5aba44 Andy McCall ↶ 277
- 2026-09-28 V6 done (oxygen-vscode#1, closed by the change). oxygen-vscode 0.8.0:
278
  - The History graph's change picker, and a right-click menu on its rows (webview context menus), offer:
279
    - Split for heads with several files: pick files; they become the first change.
280
    - Squash into a dependency, picked when there are several.
281
    - Rebase onto a bookmark, or a change or tag typed in.
282
  - Each asks first, then shows oxy's summary with an Undo button (`oxy undo`).
283
  - Client methods `split`, `squash` and `rebase`, tested against the real oxy with undo. check green (9 tests); packaged and installed into the Rust profile.
ea954efd Andy McCall ↶ 284
- 2026-09-28 V7 done (oxygen-vscode#2, closed by the change). oxygen-vscode 0.9.0:
285
  - **Amend mode** (pencil or close icon in the Source Control title bar): Ctrl+Enter amends; the box starts from the last change's message.
286
  - **Previous Commit Messages**: remembered per repository in workspace state, 30 kept.
287
  - **Signing indicator**: the placeholder says signed, sealed at push, or unsigned, read from `oxy identity show` at most every 30 s.
288
  - **Conflict marker warning** on commit, commit-selected and amend: files oxy reports with markers left, plus any changed text file with lines opening or closing a conflict (Oxygen's or Git's). The dialog can open the first one.
289
  - Pure logic in `src/commitbox.ts` with unit tests; `identity()` tested against the real oxy. check green (14 tests); installed into the Rust profile.
8e80c64d Andy McCall ↶ 290
- 2026-09-28 V8 done (oxygen-vscode#3, closed by the change). oxygen-vscode 0.10.0 and oxygenhub-vscode 0.6.2:
291
  - The line-number gutter (`editor/lineNumber/context`) and the editor context menu offer Open on Remote, Copy Remote Link and Copy Permalink.
292
  - The link covers the clicked line or the selection (`#L10-L20`).
293
  - A permalink uses OxygenHub's state address: the bookmark's heads, sorted and joined with `+`. Checked live: an 11-head address for oxygen/README.md opens with 200 on Earth.
294
  - A note appears when uncommitted edits may shift the lines, or when remote links point past unpushed changes.
295
  - `stateSpec` and `linkedLines` are unit-tested; the hub extension keeps `+` readable (tested) and its API types are brought up to date (issue editing, labels, projects). Both checks green; both installed into the Rust profile.
72bf8a02 Andy McCall ↶ 296
- 2026-09-28 V9 done (oxygen-vscode#4, closed by the change):
297
  - Both READMEs rewritten as walkthroughs by task, each claim checked against the code:
298
    - Oxygen: commit, conflicts, sync, history rewriting, bisect, line links, trust.
299
    - OxygenHub: propose, review, land, issues, releases, notifications.
300
  - Each README has a Settings table.
301
  - Every CHANGELOG entry is dated from the history.
302
  - `test/docs.test.mjs` in both fails if a setting is missing from the README or the newest CHANGELOG entry is not the package version. Both checks green (18 tests each).

- 2026-09-28 O10c done (oxygen#2, closed by the change), after splitting it.
304
  - **Measured first.** New `OXY_TIMINGS=1` phase timings, documented in the guide. At 10 000 files and 200 changes, loading the base state was about 790 of 1 230 ms. A checkpoint did not help: decoding it took 680 ms, like replaying the history, since both build the same in-memory graphs.
305
  - **Fixed without a format change:**
306
    - A seeded fast hasher for the graph maps (`fasthash.rs`, tested).
307
    - The predecessor map was written for every line and read nowhere; it is removed.
308
    - An inline edge set replaces a `BTreeSet` per vertex.
309
    - Lines are moved in with one lookup each.
310
  - **Result.** Both builds run alternately on the same load, medians: clean status 0.96 s to 0.52 s, one-file commit 0.99 s to 0.51 s, peak memory 657 MB to 239 MB (docs/benchmarks.md).
311
  - Gates green for oxygen and oxygenhub; release binary rebuilt; hub redeployed.
312
  - The rest is split into:
313
    - O10d: skip reading files that are clean by the manifest; next.
314
    - O10e: per-file checkpoints, a spec §25 format change. **Andy: this one waits for your agreement.**
315
  - Also this iteration: V6 to V8 had been installed into the Rust profile only; now into the default profile too, as the loop asks.
f97d3556 Andy McCall ↶ 316
- 2026-09-28 O10d done (oxygen#3, closed by the change):
317
  - A text file whose size and mtime match the manifest (outside the 2 s racy window), and whose recorded hash equals the base's rendering of it, takes the base's bytes instead of being read.
318
  - At 10 000 files, a clean status opens none of the files (checked with strace).
319
  - With a warm cache the walk falls only from about 75 to 56 ms, since traversal and stat remain. The gain is larger on a cold cache or a slow disk.
320
  - Test `stat_cache_takes_unchanged_text_from_the_base_and_misses_no_edit`, using unreadable files to prove what is and is not read:
321
    - an older uncommitted edit is always read, never replaced by the base;
322
    - a same-size edit made just now is caught by the racy window;
323
    - after a commit the edits become the base.
324
  - Spec §12.4. Gate green; release binary rebuilt. The hub (bare repositories) is unaffected.
325
  - Next is O10e, which waits for Andy's agreement to change the checkpoint format.
b037ade1 Andy McCall ↶ 326
- 2026-09-28 O10e done (oxygen#4, closed by the change). Spec §11, Draft 0.8j.
327
  - **Format.** Payload version 2: a file graph encoded in 2 KiB or more is a blob of its own, named from an index; smaller ones stay inline. Blobs are content addressed, so unchanged files are shared between checkpoints.
328
  - **Compatibility.** Readers accept both versions; writers produce version 2. gc keeps the graph blobs, fsck checks them against a full load in the payload's own version, and shallow-clone bundles carry them.
329
  - **Speed.** The first cut was slower than version 1, because it read 10 000 blobs one at a time. So the store gained `get_many`, which reads loose objects in parallel and packed ones in parallel after one index pass, and the graphs are decoded in parallel.
330
  - **Result at 10 000 files, 216 changes** (the same binary reading both versions, alternated, medians): load through a checkpoint 615 ms (v1) to 342 ms (v2). The index is 2.4 MB against a 62 MB v1 payload. A second checkpoint after a one-file edit took 0.63 s against 1.08 s.
331
  - **Tests.** Unit tests for the v2 round trip, determinism, missing blobs and unknown versions, and `get_many` over loose, packed and missing objects. A repository test covers a large file's graph blob through gc, fsck, a shared second checkpoint, the shallow bundle, an old v1 checkpoint still loading, and a lost blob failing loudly.
332
  - Gates green for oxygen and oxygenhub; release binary rebuilt; hub redeployed.
333
  - **Andy:** oxy older than this cannot read checkpoints written from now on. Rebuild every copy, as ~/.local/bin/oxy already is.
334
  - **New priority from Andy:** dogfood OxygenFlow on every push (F1–F5, ahead of O10f and O10g).
335
    - The runner is live on Earth, but only oxygenflow has a pipeline, of light shell jobs in a 256 MiB, one-CPU Alpine microVM.
336
    - No Rust or Node sandbox exists yet.
6f16ce2b Andy McCall ↶ 337
- 2026-09-28 F1a done (oxygenflow#2, closed by the change). Andy said go ahead with the Earth work for F1.
338
  - **Mounts.** Jobs may now declare up to 4 ephemeral scratch mounts:
339
    - `ephemeral://tmpfs` uses guest memory; `ephemeral://disk` is a fresh sparse ext4 disk per job, attached as vdc onward.
340
    - Targets are clean paths strictly under /src or /tmp and may not nest; sizes run from 16 MiB to 64 GiB. Other sources and settings are refused as not in M0.
341
    - Mounts are part of the canonical job (field 6, only when present, so existing pipeline hashes are unchanged) and of the receipt environment.
342
    - `flow-init` creates mount points owned by the job's user.
343
  - **Deployment.** `make deploy-runner` builds `flow` and the static `flow-init`, installs them under /home/claude/flow keeping `.prev` copies, re-pins `flow-init` in flow.toml and restarts flow-runner.
344
  - **Checked on Earth** with `flow run` in a real microVM (no hub involved): the job (uid 1001) owns the mounts, a 2 GiB disk took a 300 MiB write, a 64 MiB tmpfs refused 100 MiB, and scratch was cleaned. The next real push of oxygenflow passed on the new runner.
345
  - Tests: 2 new flow-core tests (parsing, refusals, hash stability) and a runner test for guest device numbering. Gates green for oxygenflow and oxygenhub; hub redeployed (it validates pipelines with flow-core).
346
  - Andy also confirmed that only he and I use oxy, so there is no need for backward compatibility before the release.
9b761fe2 Andy McCall ↶ 347
- 2026-09-28 F1b done (oxygenflow#3 and oxygen#6, closed by the changes).
348
  - **The build image** (`oxygenflow/images/rust`):
349
    - Rust 1.97.1 with rustfmt and clippy, and Node 24.21.0 (SHA-256 checked).
350
    - Every crate of the oxygen, oxygenhub and oxygenflow lock files, vendored, with cargo pointed at them via /.cargo/config.toml and `offline = true`.
351
    - Toolchain binaries are linked into /usr/local/bin, so no rustup is needed at run time.
352
    - `build.sh` builds it; Docker is only a file-system builder on the workstation (Andy agreed). Imported on Earth as `cas://blob/3ba0779a55b1d66fce10adf5a01585624c9aab089f590d228368c38fd3e65a46` (2.2 GiB).
353
    - Rebuild it when a Cargo.lock changes.
354
  - **Running oxygen's gate in it found three real problems:**
355
    - `flow-init` called glibc's `execvpe`, which searches PID 1's own (empty) PATH rather than the job's, so programs outside /bin and /usr/bin were not found. It now resolves them itself (tested).
356
    - Tests serving on 127.0.0.1 need a loopback interface. `network "loopback"` (already in the spec) is now in M0: `flow-init` brings up `lo`, with still no device leaving the guest (tested).
357
    - oxygen's `git_import_reproduces_trees` only passed where git has a user identity, because one merge lacked `-c user.name`. Fixed; it now also asserts the merge started.
358
  - **Result:** oxygen's full gate (fmt, clippy -D warnings, every test) passes in a microVM on Earth in 135 s cold, with 8 GiB, 4 CPUs and a 24 GiB disk mount.
359
  - Runner and hub redeployed; Earth scratch cleaned.
28fee1c9 Andy McCall ↶ 360
- 2026-09-28 Andy agreed the order for his five ideas: F2–F5 first, then conflict resolution (P1, P1b), function history (P2), swimlanes (P3), signed receipts and the trust dashboard (P4, P4b), then web workspaces (P5, P5c).
361
  - Decisions from the discussion:
362
    - Web workspaces start from openvscode-server unmodified, not a VS Code fork.
363
    - Hub-side history rewrites are plans applied and signed by the author's client, only on proposal bookmarks.
364
    - Function history uses atom identity rather than the semantic-deps hook.
365
  - Andy asked the loop to carry straight through all of it.
66eb6469 Andy McCall ↶ 366
- 2026-09-28 F2 done (oxygen#6, closed by the change).
367
  - **The pipeline** (`.flow/pipeline.kdl`) runs on every push to oxygen:
368
    - `fmt` in a small sandbox (1 GiB, 1 CPU, isolated);
369
    - then `clippy -D warnings`, `test --workspace` and a release `build`, each with `--locked` in the build image (8 GiB, 4 CPU, loopback) with a 24 GiB scratch disk for target/.
370
  - **First run** (#6, passed): fmt 13 s, clippy 46 s, test 1 min 37 s, build 2 min 7 s; 4 min 44 s end to end. The runner runs one job at a time.
371
  - The jobs show as checks on the change. Required checks come with F5.
372
  - The run shows "site token" as its pusher: Andy asked why pushes are not attributed to him. They use the site push token from hub.toml, set up before accounts existed.
373
    - Waiting on Andy for a personal access token (Settings › Tokens, repo:write) to put in every repository's `earth` remote.
374
    - Then, with his OK, remove the site token from hub.toml.
21352ce5 Andy McCall ↶ 375
- 2026-09-28 Pushes now use a personal access token for Andy's account in every repository's `earth` remote, not the site push token, so the hub records them as andymccall. The site token stays in hub.toml until Andy agrees to remove it.
85df6b4c Andy McCall ↶ 376
- 2026-09-28 F3 done (oxygenhub#19, oxygenflow#4, oxygen#8, closed by the changes). Andy chose pinned subrepos.
377
  - **Subrepos.** oxygenhub pins oxygen and oxygenflow as subrepos in deps/ and builds against them.
378
    - `make pins` pulls them to main on Earth; the next commit records the new pins.
379
    - A Cargo `paths` override that kept local builds on the sibling checkouts warned that it will become a hard error, so there is none: local, CI and deploy all build the pins.
380
  - **OxygenFlow.**
381
    - Claims list the state's pinned Oxygen subrepos that the pusher can read, and the job token may read those (and nothing else).
382
    - The runner fetches and exports each at its path, inside the scope hash.
383
    - Hub test `claims_carry_pinned_subrepos_and_the_job_token_reads_only_those`.
384
  - **oxy fix.** `submodule add` probed URLs without OXY_TOKEN and OXY_CA, so a hub with its own CA, or a private repository, fell back to git. It now reports the Oxygen error too.
385
  - **Formatting.** `cargo fmt --all` in oxygenhub also formats the path dependencies in deps/, with the hub's style, since oxygen has no rustfmt.toml. The pipeline and the loop's hub gate use `cargo fmt -p oxygenhub -p hub-api`.
386
  - **First run** (#12, pushed as andymccall, passed): fmt 5 s, clippy 1 min 49 s, test 4 min 1 s, release build 8 min 26 s. The runner runs one job at a time → F6.
387
  - Also this iteration: removed fix.py, fix2.py and format_xenon.py from oxygen (Andy's request, oxygen#7). Answered Andy's VS Code question: the extension is installed in both profiles and only shows in an Oxygen repository.
9ce6f084 Andy McCall ↶ 388
- 2026-09-28 F4a done (oxygenflow#5, oxygenhub#19, closed or referenced by the changes).
389
  - **Pinning.** oxygenflow pins oxygen at deps/oxygen, with `make pins` and a README note.
390
  - **oxygenflow's pipeline** adds fmt (this workspace only), clippy -D warnings and tests on the build image, before its summary. First run #14: all 8 jobs passed.
391
  - **The hub's layout had to change.** oxygenflow's flow-core now points at its own deps/oxygen, so the hub keeping a second oxygen pin would give Cargo two different oxy-core packages. The hub now pins only oxygenflow and builds against deps/oxygenflow/deps/oxygen.
392
    - The chain for newer code: push oxygen, then `make pins` in oxygenflow and push it, then `make pins` in oxygenhub.
393
  - **Nested subrepos.** Hub claims follow subrepos of subrepos, parents first, joined paths, up to 3 deep, with the same read check. The hub test covers a pin inside a pin.
394
  - **Result.** oxygenhub run #15 fetched deps/oxygenflow and deps/oxygenflow/deps/oxygen and passed: fmt 2 s, clippy 1 min 37 s, test 3 min 44 s, build 6 min 25 s.
395
  - **Also fixed** for Andy: `oxy identity export` failed in a new repository, because identity lookups ignored the key directory. It now falls back to it, checked against the key, and the help names the file it writes (oxygen#9).
3498fb47 Andy McCall ↶ 396
- 2026-09-28 F4b done (oxygen-vscode#5, closed by the change; oxygenhub-vscode references it).
397
  - **Image.** The build image (now `85c744e5…`) also carries an npm cache of both extensions' lock files. `npm ci --offline --cache /opt/npm-cache` installs from it read-only; checked locally before building.
398
    - oxygen, oxygenhub and oxygenflow still pin the previous image `3ba0779a…`; they move on their next re-pin.
399
    - Rebuild the image when a package-lock.json or Cargo.lock changes.
400
  - **oxygen-vscode** pins oxygen as deps/oxygen (kept out of the .vsix). Its `check` job builds oxy from the pin on a scratch disk and runs typecheck, bundle and the 18 tests against it; then `package`.
401
  - **oxygenhub-vscode:** check and package. Its hub-client tests skip in the VM, since there is no hub binary there.
402
  - **First runs:** `package` failed in both, because a job starts from a fresh workspace and had no dist/. It now builds first.
403
  - **Green:** oxygen-vscode #21 (check 1 min 8 s, package 6 s), oxygenhub-vscode #22 (check 7 s, package 5 s). oxygenflow #20 passed all 8 jobs.
404
  - All five repositories are now linted, tested and built by OxygenFlow on every push.
9a239f06 Andy McCall ↶ 405
- 2026-09-28 F5 done (oxygenhub#20, referenced by the changes).
406
  - **Required checks over the API.** They could only be set from the settings page, so the hub gained `GET` and `PUT /api/v1/repos/{o}/{n}/checks/required` (admins, the whole list, audited). Tested; TS regenerated; hub deployed.
407
  - **Required checks set on every repository:**
408
    - oxygen and oxygenhub: flow/fmt, clippy, test, build;
409
    - oxygenflow: flow/fmt, clippy, test, summary;
410
    - both extensions: flow/check, package.
411
    - Proposals cannot land on main without them.
412
  - **Waiting for green.**
413
    - `oxy push --json` now reports the state each bookmark was pushed to (tested).
414
    - New `flow wait <repo URL> <state>` follows that state's checks on the hub against the required ones: exit 0 passed, 1 failed (a failed check, or a skipped required one), 2 at the time limit. Unit-tested.
415
    - First real use: it followed oxygenflow's own run for the change that adds it, 8 checks from queued to passed, and exited 0.
416
  - **From now on the loop pushes and waits** with `flow wait` after the local gate, and a red run is fixed before an item counts as done. Recorded in my working notes; Andy's loop prompt file is unchanged.
417
  - F1 to F5 (dogfooding) are done. F6 (faster runs) is next in the F group; then P1 and the rest.
3c5c6ad2 Andy McCall ↶ 418
- 2026-09-28 O10f done (oxygen#10, closed by the change; OxygenFlow run green, followed with `flow wait`).
419
  - **History-only states.** `Repo::load_state_history` keeps changes and tree but builds no file graph.
420
    - From a version 2 checkpoint, graphs stay as pending blob refs or inline values.
421
    - By replay, each change's edits wait per file.
422
    - `load_graphs` builds the graphs asked for, in one blob batch, identical to a full load (tested against full payloads, by replay and from a checkpoint with later changes).
423
    - An unloaded graph panics with a clear message rather than reading as empty, and `materialize` refuses a history-only state (both tested).
424
  - **Used by** `log`, `log_state`, `log_for_path_in` and `blame_in` (one graph).
425
  - **At 10 000 files:** the log's state load 270 → 37 ms, `oxy log` 0.89 → about 0.7–0.8 s. The rest is the working-copy snapshot the log takes first (O10g). CLI `blame` works from the snapshot, so it is unchanged (0.6 s).
426
  - **Andy asked:**
427
    - Why his pushes show "site token": his repositories metalgear, rstar-api and snake-oxy use hub.toml's site push token (c085…). Told him to make his own personal token and set it with `oxy config remote.earth.token`. Removing the site token waits for his OK.
428
    - The oxy equivalent of git-flow: bookmarks and `oxy merge` (a union, no merge change), proposals, tags. Answered.
da29defd Andy McCall ↶ 429
- 2026-09-28 F6a done (oxygenflow#6, oxygenhub#21, closed by the changes).
430
  - **The runner** runs up to `max_jobs` jobs at once within a memory and vCPU budget (flow.toml).
431
    - It reports its free room when it claims, and the hub hands out only a job whose sandbox fits; a lone job may use the whole budget.
432
    - Preparing workspaces stays one at a time: shared repository caches, and the first clone's token in the environment.
433
    - Unit-tested budget; the hub was deployed before the runner.
434
  - **Measured honestly: parallel Rust jobs are slower on Earth's 4 cores.** Oxygen's run took 345 s with clippy beside test and build (clippy 46 s → 1 min 53 s, build 2 min 7 s → 4 min 49 s), against 284 s one at a time.
435
    - Earth's budget is therefore max_jobs 3, 24 GiB and **5 vCPUs**: one 4-vCPU Rust job at a time, with 1-vCPU and short jobs beside it.
436
    - The real speed-up is F6b (prebuilt dependencies, release without debug info).
437
  - **Found on the way:** OxygenFlow log appends failed with HTTP 500 "database is locked", losing log lines.
438
    - Cause: the hub's write transactions were deferred and read before writing, which SQLite fails at once whatever the busy timeout.
439
    - All 9 now begin IMMEDIATE (`db::begin_write`). A test of 16 concurrent appends fails with the old code and passes now.
440
    - Deployed; the next oxygenhub run passed with no new lock errors in the runner's log.
441
  - **Andy asked** whether an `oh` command, like GitHub's `gh`, should be its own repository. Recommended a crate in the oxygenhub workspace, since it shares hub-api and can test against a real hub. Asked where in the backlog he wants it; no answer yet.
57dfc514 Andy McCall ↶ 442
- 2026-09-28 O10g, first part, done (oxygen#11, closed by the change; OxygenFlow run green, followed with `flow wait`). Spec §12.4, Draft 0.8k.
443
  - **Graph keys.** `State::graph_key` hashes a file's node, its checkpoint graph (blob, inline value or none) and the set of later changes that edited it. Equal keys mean equal graphs, and so equal renderings.
444
    - A test caught my first version, which left the node out: two files edited only by the same change got the same key.
445
  - **What the manifest records.** Per text file found equal to the base's unconflicted rendering, the key it matched.
446
    - When a file's stat and key both still match, the snapshot neither reads nor renders it.
447
    - `.oxyattributes` files are always read. When any of them is added, removed, edited or changed in the base, nothing is skipped.
448
  - **`Repo::snapshot_status`** gives a partial snapshot: a history-only base with only the other graphs built, and a `Snapshot.unrendered` list.
449
    - Used by status, log, show, tag, bookmark create/set, the default head, and `pull --json`.
450
    - `snapshot` (commit, diff, amend…) still builds the whole base. Its graphs now load in parallel.
451
  - **Tests:** 3 new; 157 core tests pass, clippy is clean.
452
  - **At 10 000 files:** a clean status takes 0.22 s instead of 0.55 s, and 51 MB instead of 259 MB. Log takes 0.38 s instead of about 0.75 s. Diff and commit are unchanged at about 0.57 s.
453
  - **Split:** O10h (a lazy base for commit and diff, and cached materialized states) is added to the backlog.
c1fe1fb2 Andy McCall ↶ 454
- 2026-09-28 **Metalgear feedback.** Andy's other project reports what it finds in `~/oxygen_feedback.md`; I watch it and act on it. Its items are M1 to M10, placed ahead of P.
455
  - **M1 done** (oxygen#12). Pushing a bookmark with `/` in its name failed with "No such file or directory".
456
    - Cause: reference attestations and checkpoint pointers are files named after the bookmark, and nothing created the subdirectory.
457
    - They are now one flat file each, with `/` escaped (`%2F`), so `feature` and `feature/x` coexist.
458
    - A test pushes and checkpoints both.
459
    - Pinned through oxygenflow into oxygenhub and deployed. All three OxygenFlow runs are green.
460
  - **M2 done** (oxygenhub#22, Andy's request). Settings → OxygenFlow has on, off or site default (hub.toml's `[flow] repos`), and needs no restart.
461
    - Site administrators change it; repository admins only see it.
462
    - Audited as `repo.flow`; migration 0018.
463
    - Two tests; hub gate green; deployed; run green.
464
  - **Andy asked urgently** to enable Flow for doomsdayone/metalgear.
465
    - My edit of hub.toml on Earth was refused by the permission check, so I did not make it.
466
    - The line `"doomsdayone/metalgear"` is now in `[flow] repos`, added outside this loop, and run #37 there passed.
467
    - From now on the new setting does this without editing hub.toml.
2dd42fa1 Andy McCall ↶ 468
- 2026-09-28 **M11 done** (oxygenhub#23; Andy asked for it urgently). Flow runs are numbered per repository.
469
  - Run list, run page (`/flow/{number}`), live view, stamp and check links all use the number.
470
  - Migration 0019 numbered the existing runs per repository in creation order and rewrote the links of existing flow checks.
471
  - I tried it first on a read-only copy of Earth's runs and checks: 160 of 185 links changed, and every link names a run of its own repository.
472
  - Live: metalgear's run is #1, oxygen's #1 to #19. Hub run green.
473
- 2026-09-29 **M12 done** (oxygen#13, oxygenhub#24; Andy asked, and feedback 14a).
474
  - **`oxy push REMOTE --delete NAME`** sends an update to the zero state.
475
    - Checked like any update: the bookmark must exist at `old_state`, and a policy needs an authorized key.
476
    - The deletion's attestation stays the bookmark's latest, so an old one cannot be replayed to bring it back.
477
    - So a bookmark new to a remote starts its serial at the clock in milliseconds.
478
    - The local bookmark is kept.
479
  - **The default bookmark is never deleted.**
480
    - A non-bare repository protects its checked-out bookmark.
481
    - For a bare one, the host says which is the default through `Backend::default_bookmark`: `oxy serve` uses the configured bookmark, the hub its setting.
482
  - **Hub:** a DELETE button (with a confirmation) for writers on every bookmark but the default. It goes through the same checks, is logged on the pushes page and sent to webhooks as a push.
483
  - **Tests:** core, HTTP and hub, one each. Spec §16.4 (Draft 0.8l) and hub spec updated. Deployed; all three OxygenFlow runs green.
484
  - metalgear's `flow-first-run` can now be deleted; I left that to its project.
485
  - **Feedback file:** new items 3a and 7a became M13 (`bookmark switch --carry`) and M14 (`oxy show` summary lists every kind).

- 2026-09-29 **M14 done** (oxygen#14). `oxy show`'s summary names every file the change touches: an `M` line for each edited file without a tree operation, and renames with their full new path. Tests updated; run green.
487
- 2026-09-29 **M13 done** (oxygen#15).
488
  - `oxy bookmark switch NAME --carry` takes uncommitted work along (edits, additions, removals, renames).
489
    - It needs every touched path to be the same in NAME's state as in the working copy's base, so the same edits apply there.
490
    - Otherwise it refuses, changes nothing, and names the paths.
491
  - `bookmark create feat && bookmark switch feat --carry` moves work onto a new bookmark.
492
  - The switch help and spec §10.1 say what happens to uncommitted work, which also answers part of feedback 3.
493
  - One test; run green.

- 2026-09-29 **M3 done** (oxygenhub#25; feedback 9).
495
  - **Web:** writers get RUN PIPELINE on the Flow tab (a bookmark's current state) and RE-RUN on a finished run's page.
496
  - **API:** `POST /api/v1/repos/{o}/{n}/flow/runs` and `…/runs/{n}/rerun`, with `repo:write`. They answer 201 with the number and url, or 409 with the reason.
497
  - A new run's checks replace the old ones for that state.
498
  - Runs record what started them (migration 0020), and the run page says "pushed by", "started by" or "re-run of #N by".
499
  - Pushes and both new paths share `flow::start_run`.
500
  - One hub test; gate green; deployed; run green.

- 2026-09-29 **M4 done** (oxygenflow#7; feedback 15 and 17).
502
  - **/dev links.** flow-init adds `/dev/fd`, `/dev/stdin`, `/dev/stdout` and `/dev/stderr` into `/proc/self/fd`.
503
  - **Job variables.** Claims carry the run's state hash, bookmark and number. The runner adds `FLOW_REPO`, `FLOW_STATE`, `FLOW_HEADS`, `FLOW_BOOKMARK`, `FLOW_RUN` and `FLOW_JOB` to the job's environment, so they are in its receipt too.
504
    - `flow run` sets `FLOW_JOB` and `FLOW_RUN=local`.
505
    - A pipeline's own value wins; unknown values are left out.
506
  - **Tests:** unit tests for both, and the hub test checks the claim's new fields. Hub and runner deployed (runner with `.prev` copies).
507
  - **Proved in a real microVM on Earth:** `< <(echo …)` works, the links are there, and the variables arrive.
508
- 2026-09-29 **"database is locked" again** (oxygenflow#8).
509
  - At 00:40 and 01:01, during oxygenhub runs, log appends and a claim got HTTP 500 after the 5 s busy timeout, and the runner dropped those log lines.
510
  - It was not the hub restarting (up since 00:51) nor the WAL (4 MB). Most likely a commit stalled while the release build saturated Earth's disk. Not proven.
511
  - **Runner:** tries 5xx answers again after 1, 2 and 4 s; a 4xx is final. Tested against a fake hub.
512
  - **Hub:** busy timeout 30 s.
513
  - No lock errors in the runs since, including a full oxygenhub run.

- 2026-09-29 **M5 done** (oxygenflow#9; feedback 16).
515
  - **Sandbox env.** A sandbox takes an `env` block that every job in it starts from; a job's own `env` overrides it.
516
    - It is canonical field 6, only when set, so existing pipelines keep their hashes.
517
  - **Image environment.** `flow rootfs import --env NAME=value` writes the image's own environment to `/etc/flow/env`: what a Dockerfile's `ENV` sets and `docker export` loses. It is covered by the image's hash.
518
  - **Layers in flow-init:** `PATH` and `HOME`, then the image's environment, then the job's. The program is found in the resulting `PATH`.
519
  - **Tests** for parsing, precedence, hashing, layering and `--env` checks.
520
  - Hub pinned and deployed, since it parses pipelines. Runner deployed.
521
  - **Proved in a microVM on Earth:** a program found only through the sandbox's `PATH` ran, with the job's value winning. The image layer is unit-tested; nothing was re-imported on Earth.

- 2026-09-29 **M6 done** (oxygenhub#26; feedback 11 and 13; run numbering was M11).
523
  - `GET /api/v1/repos/{o}/{n}/flow/runs`, `/flow/runs/{n}` (with its jobs) and `/flow/runs/{n}/jobs/{job}/log?after=seq`, typed in hub-api.
524
  - `/checks/{state}` also takes heads joined with `+`, a single head, or a bookmark.
525
  - Unknown `/api/v1` routes answer with a JSON problem.
526
  - **Found on the way:** two flow tests raced the checks a run reports just after it is recorded, and one failed in a full run. They now wait for the checks.
527
  - Deployed and tried live: oxygen's runs #28 and #27 listed, and the JSON 404. Hub run green.
