Tier: T2

Rebased once onto 43b2cb17: the one real conflict was the diagnostics.js import line (their access/constants and my readdir/basename, taken as a union); the test file and the docs paragraph kept both sides' insertions; patches/ds-bot/ was taken from the new base and re-out by generate. Against 43b2cb17 the branch is one commit and the six files below — nothing of #2432 or #2436 rides along.

What changed

• core/src/host/diagnostics.js: one new line in the team-file block, right after state file:. It names the backups the store actually leaves beside the team file — state.json.v1 (the one-time version-1 migration backup, core/src/host/store.js:123-143) and the state.json.broken-<stamp> copies of a file that could not be read (store.js:199) — as name (12 KB, 2 h ago), newest first, three broken copies at most with and k more counting the rest, or none when neither family is there. A name lstat itself cannot answer for says unreadable: <code>; a directory or a dangling link is drawn from its own size and age like any other name, so no sentence is invented for it. The line never throws and never opens a backup: lstat for each name and one readdir(home) filtered by the exact state.json.broken- prefix — a backup holds the same members, messages and saved keys as the team file, and this report is written to be pasted into a public issue.
• core/test/diagnostics.test.js: five cases covering none, a readable .v1 with size and age (which also proves the rest of the report is unchanged: the line is the only added one), a home this host cannot lstat through where the .v1 says EACCES while the report still prints, a directory and a dangling link that keep the size-and-age shape from their own lstat, and five .broken-<stamp> copies that are listed newest first with and 2 more while an unrelated file in the home is not listed. A locked window also asserts its Read-only row is unchanged.
• docs/subsystems/core-host.md (the page that owns core/src/host/): the state-file paragraph now states the backups line, its exact shape and the no-open rule.
• changelog.d/2434-state-backups.added.md.
• patches/ds-bot/0001-core-fixes.patch and 0007-version-and-tooling.patch re-out from generate; nothing else in the patch series moved.

Ran

Red first, on clean 43b2cb17 with only the new cases added (cd core && TZ=UTC node --import ./test/harness-resolve.mjs --test test/diagnostics.test.js):

not ok 30 - a host with no state backups says none
not ok 31 - one readable backup is named with its size and age, and no other line moves
not ok 32 - a backup whose lstat fails is named with its code and the report still prints
not ok 33 - a backup that is a directory or a link to nothing is drawn from its own lstat
not ok 34 - the broken copies are listed newest first, three at most, with the rest counted
# tests 63 # pass 58 # fail 5

The same five failed on the original base 16d16456 (# tests 62 # pass 57 # fail 5, not ok 29–33). With the change, the same file is # tests 63 # pass 63 # fail 0.

At this tree (a78f3c625b393093033013e82a835d626c6bd23b, verified commit 0cc378a61af28e61c82a199c48f74d01375750d4):

• TZ=UTC ARCH_DOCS_BASE=43b2cb17 npm run verify — exit 0, 4859/4859 (core 2862, social 574, tree 136, timeline 141, workflow 412, root 671, interop 37, live-e2e 26), fail 0 / cancelled 0; core lint 77 warnings / 0 errors, plugin lint 36/9/2/16 warnings / 0 errors, interop lint 1 warning / 0 errors, live-e2e lint 0 warnings / 0 errors.
• ARCH_DOCS_BASE=43b2cb17a39a177517b5b7e67c8216859c88b4a5 npm --prefix core run arch-docs on the committed tree — arch-docs: OK (6 changed file(s)).
• node scripts/ds-bot-patches.mjs generate twice — second run no-op, git status --porcelain empty afterwards.
• node scripts/ds-bot-patches.mjs check — 10 patches apply cleanly in order, core/ equals ds-bot/ + patches/ds-bot/.
• node scripts/ds-bot-patches.mjs canonical — patches/ds-bot/ is what generate writes (generate is a no-op).
• node core/scripts/build-client.mjs --check — exit 0 (part of verify).
• node .github/scripts/changelog.mjs check — 35 fragment(s) in changelog.d/ are well formed.
• node .github/scripts/check-empty-catch.mjs — exit 0.
• node .github/scripts/check-mojibake.mjs — 0 occurrences of U+FFFD in 1471 text file(s).
• risk tier, live main 43b2cb17 rules with each changed file's patch content: risk-tier: T2; basis: core/src/host/diagnostics.js=T2, changelog.d/2434-state-backups.added.md=T1, core/test/diagnostics.test.js=T1, patches/ds-bot/0001-core-fixes.patch=T1, patches/ds-bot/0007-version-and-tooling.patch=T1, docs/subsystems/core-host.md=T0; why: [] (no rule matched the patch content); 153 changed lines / 4 non-generated files / 2 generated patch files.

Not run

• No smoke test: this is one line of the diagnostics report — no request path, no endpoint, no client bundle.
• No manual DSH run and no live-E2E beyond the suite's own 26.
• No change to the store: the backup names and the rotation-free save path are what store.js already does; only the report reads them.

@Birfy review request for this exact tip: 07e7ecf0e80f9d8e893a1f1b7462f9dc4635fcda (base 16d16456f14023a24228730a98487b585cf08441, Tier: T2, non-draft, maintainer_can_modify: true).

Ready at this tip: red-first on a clean 16d16456 with only the new cases is 57 pass / 5 fail (the five new state backups: cases), the tip is 62/62; npm run verify 4848 with 0 fail, patches check 10 patches + core/ equals ds-bot/, generate second run no diff, arch-docs OK(6), lint 0 errors. checkpointReasons() on the current body is [].

Two independent advisory reads already pass at this tip, both read-only and neither is a Verdict: FlyBot Test (no absolute path in the report, zero O_RDONLY on any backup under strace, every other report line byte-identical) and FlyBot Security (lstat-only with AT_SYMLINK_NOFOLLOW, no follow out of the home, no write, no path leak). enqueue-guard is red only because no Verifier report names this tip yet; everything else at the tip is green.

Please review 07e7ecf0e8 and post Verdict: PASS (or the changes you want). No new tip will be pushed for CI noise.

Blocking: this tip cannot enter the queue, so a PASS here would be spent on a head that can never be enqueued.

• core/src/host/diagnostics.js:8 — expected: the branch sits on live main 648944d6 and the pull request reports mergeable=true (the merge queue refuses an unmergeable head); actual: base 16d16456, 5 commits behind, mergeable=false, mergeable_state=dirty. host: a team file linking to a file it cannot read is still reported as read through the link #2432 (648944d6, merged after this branch's base) edits the same import block: it writes line 7 import { constants, readFileSync } from 'node:fs' and line 8 import { access, appendFile, lstat, … }, while this PR writes line 8 import { appendFile, lstat, mkdir, readdir, … } and line 10 import { basename, dirname, join }. Both sides change line 8 — a three-way conflict — and a careless resolution also drops the access/constants import that host: a team file linking to a file it cannot read is still reported as read through the link #2432's describe path needs.
• patches/ds-bot/0001-core-fixes.patch, patches/ds-bot/0007-version-and-tooling.patch — expected: regenerated from the merged core and node scripts/ds-bot-patches.mjs check clean; actual: both were regenerated against the stale base, so they conflict too.

How to fix (on HugoXK/FlyBot branch dev/1-state-backups):

1. Update onto main 648944d6 (gh pr update-branch 2440, or rebase/merge origin/main). The tip then moves and this review no longer applies.
2. Resolve the import block by keeping both sides: line 7 import { constants, readFileSync } from 'node:fs'; line 8 import { access, appendFile, lstat, mkdir, readdir, readFile, rename, rm, stat, writeFile } from 'node:fs/promises'; line 10 import { basename, dirname, join } from 'node:path'.
3. node scripts/ds-bot-patches.mjs generate && node scripts/ds-bot-patches.mjs check, then TZ=UTC ARCH_DOCS_BASE=648944d6 npm run verify.
4. Push and re-request review at the new tip; the new tip needs its own PASS (this conclusion names 07e7ecf0 only).

Not run: the suite at this tip — the branch has to move first, so a run at 07e7ecf0 would judge a head that can never merge; the rebased tip gets core/test/diagnostics.test.js and its red-first revert. The checkpoint / Owner: / Reviewer: / agent-pr reads are exempt for a fork head (pull.head.repo.full_name is not ThinkFlowLab/FlyBot), so the body was left as the author wrote it.

@Birfy review request for this exact tip: e1411d8788ca55819c86569ada12e1781de7a8f8

This head is the rebase your REQUEST_CHANGES at 07e7ecf0e80f9d8e893a1f1b7462f9dc4635fcda (comment 6638793669) asked for. All three items, at this tip:

1. Base moved to live main 43b2cb17a39a177517b5b7e67c8216859c88b4a5 (after #2432 and #2436); mergeable=true, single commit, 6 files +298/−12 — the same per-file counts as the pre-rebase head, so the resolution rewrote no logic.
2. Import block resolved exactly as prescribed: :7 import { constants, readFileSync } from 'node:fs'; :8 import { access, appendFile, lstat, mkdir, readdir, readFile, rename, rm, stat, writeFile } from 'node:fs/promises'; :10 import { basename, dirname, join } from 'node:path'.
3. Both patch files re-emitted from the new main: patches check → ok ds-bot/ = Fei2411/DeepSeek-Bot@2b10c70, 10 patches apply cleanly in order, core/ equals ds-bot/ + patches/ds-bot/; a second generate is a no-op and canonical says generate is a no-op.

Nothing of #2432 rides along. In pull/2440.diff the access(path, R_OK) path and stateNotPlain appear only as context lines; the added lines in core/src/host/diagnostics.js are the stateBackups() block, its two import names, and the one stateBackups: call. git diff 43b2cb17 -- core/src/host/diagnostics.js | grep -E '^\+.*(R_OK|access\()' → 0 lines, and unreadable: appears exactly once, in backupProblem.

Red first on the new base with only the new cases: # tests 63 / # pass 58 / # fail 5 (not ok 30–34); with the change the same file is 63/63 (the #2428 case included). TZ=UTC ARCH_DOCS_BASE=43b2cb17 npm run verify — exit 0, 4859/4859, fail 0.

Checks at this tip: 15 success; enqueue-guard is red only because no Verdict names this tip yet. The Security advisory for this head is being re-run and is advisory.

Verified at this tip: core/test/diagnostics.test.js 63/63; on main 43b2cb17 with only the new cases 58/63 (the five new state backups: cases red). node scripts/ds-bot-patches.mjs check: 10 patches apply cleanly, core/ equals ds-bot/ + patches/ds-bot/. The import block keeps main's constants/access (#2432) and adds readdir/basename; the docs line and changelog.d/2434-state-backups.added.md are present. tests-ok is green at this tip; enqueue-guard is red only because no conclusion names this head yet.
