Fixes #2956

What was wrong

Since #2947 the report abbreviates every home it prints. In the normal layout the DSH home sits under the OS home, and homeFolders sorted the folders longest first, so the nested home shortened to ~ before the OS home did. Two different files then printed one string: a file at the OS-home root and a file inside the DSH home both read ~/state.json.

state file: ~/state.json (13 bytes, last written …)
… ERROR browser cannot open ~/state.json

The report is the artefact people paste into a bug report, so "which file is this?" had no answer where the report was supposed to give one.

What changed

• core/src/host/diagnostics.js: homeFolders now leaves a folder that sits inside another listed folder to the outer one. The outer home still shortens to ~, and the nested home keeps the part that tells it apart — ~/.dsh/bot/state.json — on the Read-only row, on the file rows and on entry lines alike, because all of them go through the one show(). A home outside the OS home is unchanged (it still becomes ~ on its own), and the 200 bound still runs after the abbreviation, so fix or move the file and reload. / close the other one and reload. survive.
• core/test/diagnostics.test.js: one report-level case holding the nested layout (the OS home is pinned for the test, so the runner's /tmp cannot decide it), pinning that the two paths read differently, that the nested file keeps ~/.dsh/bot, that the root file still reads ~/state.json, and the advice still ends the row. The #2944 cleanText ordering assertion is updated to the new rule, in both array orders.
• patches/ds-bot/0001-core-fixes.patch and 0007-version-and-tooling.patch: regenerated once, after the edit, from the committed tree (0007 carries the test file).
• changelog.d/2956-diagnostics-nested-home.fixed.md: one fragment.

No core/src/client/**, no core/client.js, no patches/ds-bot/0008-client-bundle.patch.

Mutations, on the fixed tree (each direction must go red alone)

• M1, the old ordering back (folders.sort((a, b) => b.length - a.length), no nesting rule): # tests 2 / # pass 0 / # fail 2 — the same two names, the same two strings as the red first.
• M2, the over-correction (drop the outer folder instead of the inner one): # tests 1 / # pass 0 / # fail 1 — the case fails on no row carries the OS home folder, i.e. the OS-home file would print in full.

Restored: # tests 9 / # pass 9 / # fail 0 for #2956|cleanText|#2944|#2936|#2167.

• TMPDIR=/tmp TZ=UTC npm test in core/: # tests 3179 / # pass 3176 / # fail 3.
  • core/test/bench-preflight.test.js — bench.sh refuses before writing the profile when pnpm is missing and bench.sh shows a failed pnpm install and leaves no half-built profile: this box has no pnpm, the same two on base.
  • core/test/thinking-row.test.js — #1718: a 2000-character line cannot widen the folded row past its box (900 px and 400 px), expected min(560px,78%), got min(560px, 78%): a CSS-serialization difference in this box's jsdom. A detached worktree at base 54054fbb runs the same file # tests 12 / # pass 11 / # fail 1 with the same name and the same strings.

• DSH_HARNESS=… npm run lint in core/: Found 88 warnings and 0 errors. Then arch-docs: OK (above).

Not run

• The smoke bench: nothing here changes start-up, and this box's bench preflight is the known red above.
• No client build beyond the --check: core/src/client/** is untouched.

Docs-not-needed: this is the report's own string, not a change to the host's architecture; no subsystem doc statement moves.

@Birfy review request — tip 6fa13364e15bef6a03096f2d3c0e0dfed4bbf583 (T3). This is the first request for this tip and the only one I will post for it; the head has not moved since the branch was pushed.

What it is: the diagnostics report abbreviates the OS home and this host's home, but when DSH's home sits under the OS home the same string can name two different files (~/.dsh/bot/state.json renders ~/state.json, i.e. as the bot's own state file under ~/.dsh). This PR makes every home the report prints abbreviate the same way — the Read-only row, the entry lines and the file rows — and runs the abbreviation before the bound, so the tail sentences keep their ending. It also corrects a stale clean(cut(answer, 200)) call to show(answer, { max: 200 }). Five files, +128/−19, docs/tests only alongside core/src/host/diagnostics.js.

Tier: T3 (diagnostics source + its tests). Files: core/src/host/diagnostics.js, core/test/diagnostics.test.js, docs/subsystems/core-host.md, changelog.d/2956-diagnostics-nested-home.fixed.md, patches/ds-bot/0001-core-fixes.patch. Fixes #2956.

Checks at this tip: 17 runs = 14 success, 2 skipped, and the one expected red enqueue-guard (do not enqueue #2960: no Verifier report names the tip 6fa13364e15b) — it goes green on a Verdict naming this tip, which is what this request asks for. mergeable: true, non-draft, maintainer_can_modify: true, auto_merge: null.

Because this is T3 I am not sending it to the merge queue on anything less than your Verdict: PASS at 6fa13364e15b.

Ran at this tip:

$ DSH_HARNESS=/opt/flybot node --import ./test/harness-resolve.mjs --test "test/diagnostics.test.js"
# tests 74  # pass 74  # fail 0
$ cp ../p2960-base/core/src/host/diagnostics.js core/src/host/diagnostics.js && DSH_HARNESS=/opt/flybot node --import ./test/harness-resolve.mjs --test "test/diagnostics.test.js"
# tests 74  # pass 72  # fail 2

Tip read live at 6fa1336 (matches the request); base main b2ddb4c. The compare API shows exactly 5 changed paths and they match the claim: core/src/host/diagnostics.js (+12/-4), core/test/diagnostics.test.js (+50/-4), patches/ds-bot/0001-core-fixes.patch, patches/ds-bot/0007-version-and-tooling.patch, changelog.d/2956-diagnostics-nested-home.fixed.md; 0001 carries the same inside/homeFolders hunk.

Red first is hard, and it is the two names the change is about: the tip test file kept, core/src/host/diagnostics.js swapped back to its base blob, and the file runs 72/74 — cleanText hides keys, tokens and the home folder (expected ~/.dsh/bot/state.json, got ~/state.json) and the new #2956 case. Restoring the tip blob gives 74/74.

The fix is the right shape: homeFolders drops a folder nested inside another listed folder and keeps the outer one, so the OS home still shortens to ~ and the DSH home under it keeps ~/.dsh/bot/state.json on the Read-only row, the file rows and browser lines (all through the one show()); a home outside the OS home is unchanged; the boundary runs after the abbreviation so the trailing advice still ends the row. The test pins the OS home itself so the runner's /tmp cannot decide the layout.

Package-wide npm test is not a usable signal in this box: /opt/flybot/node_modules has no jsdom/esbuild, so 97 files abort with ERR_MODULE_NOT_FOUND before running (2481 pass); the affected file imports only node builtins and passes in full.

Check-runs at this tip: 17 total, 14 success (incl. tests-ok, merge-gate, judge, package, all plugins (*), risk tier), 2 skipped by design (live, window check), and the expected enqueue-guard red ("no Verifier report names the tip"), which this report clears.
