The platform workflow's first run produced seventeen failures on Windows and
macOS, where the JavaScript suite had never executed. Two were real defects
in shipped code.
A CONTAINMENT CHECK THAT REFUSED EVERYTHING ON WINDOWS
`resolveWithinProfile` compared `target.startsWith(root + "/")` with a
hardcoded forward slash. On Windows `resolve()` returns
`C:\profile\file.txt` and the comparison asked for `C:\profile/`, so it
matched nothing: document export and import refused every path, including
legitimate ones. It failed CLOSED, so nothing leaked — the feature simply did
not work. Now uses `relative()`, which needs no separator of our choosing.
A COMMAND PARSER THAT ATE WINDOWS PATHS
`parseCommandSpec` treated backslash as a POSIX escape unconditionally, so
`--exec "C:\Program Files\tool.exe"` was spawned as the command `C:Program`
with an argument `Filestool.exe`. Every Windows path handed to --exec or
--stdin-to was mangled before the spawn. This is the SECOND instance of this
exact bug today — the Python TUI palette had it too — which is what a whole
class looks like rather than a one-off.
`windows` is an explicit parameter, not a `process.platform` read, so both
branches are tested from either platform. That parameter is the actual fix
for the class: the reason these survived is that the Windows branch could
only ever run on Windows.
THE REST WERE TESTS, NOT CODE
- `/bin/true` does not exist on macOS (it is /usr/bin/true), so a spawn failed
with ENOENT and the refusal looked like the daemon's crash-safety fix having
regressed. Now uses process.execPath, which exists everywhere by definition.
- The oversized-request test treated its own EPIPE as fatal. The daemon caps
the line, answers and hangs up; on macOS that hangup lands while the client
is still pushing the remaining megabyte. Correct server behaviour was
failing the test on one platform and passing on the other.
- Three sink tests wrote `#!/bin/sh` files. Shebangs and /bin/sh do not exist
on Windows. Now Node scripts run by the interpreter already running the
tests.
- Eight `0600` assertions and two clipboard tests are guarded by documented
constants in test/helpers/platform.ts. Windows has no POSIX mode bits and
the runner has no clipboard.
The skips state a gap rather than closing it, and TODO.md now records that the
Windows permissions question grew from two Python tests to ten across both
languages — including the vault index and the semantic index, which hold
secrets. With TypeScript becoming the only implementation that is a shipping
question, not a test-suite one.

Two findings from the 2026-08-18 audit, entangled in the same files.
L-4 — the additional backup location was inert. The TUI accepted a path and
answered "Additional backups will be written to X"; nothing ever wrote one.
That is worse than an absent setting: it is false assurance in the feature a
user leans on precisely when everything else has gone wrong. The cause was
larger than the setting — Python's BackupManager is not ported at all, so
`backup_interval` was dead for the same reason.
New backups.ts ports the write side: after every committed mutation, the
encrypted index is copied to <profile>/backups/entries_db_backup_<ts>.json.enc
at 0600, and mirrored to `additional_backup_path` as <fingerprint>_<name>.
Filenames match Python's byte for byte so the two implementations share one
backup directory. Hooked after the save in both mutation funnels, matching
Python's create_backup()-after-_save_index() order, so a snapshot is the
post-mutation state.
Two deliberate deviations, both documented in the source:
- Throttling reads the newest snapshot on disk rather than Python's
in-memory _last_backup_time. Every CLI command is its own process, so an
in-memory counter would make backup_interval inert for CLI use — the same
bug in a new place.
- A failed mirror is reported rather than swallowed. Best-effort must not
fail a committed vault write, but silence would restore the false
assurance this change exists to remove.
Quick Unlock stays in the menu for item-order parity but now says it is not
implemented instead of storing a preference nothing reads. In Python the flag
never changed unlocking either — it writes an audit entry and raises a
security finding.
L-8 — plaintext backup import was not bound to a profile. A seed-only backup
is implicitly seed-bound: the wrong seed cannot decrypt it. A plaintext one
imports into any profile and is then re-derived from the TARGET seed, so every
password, SSH key, PGP key and seed silently comes out different from the one
the backup was taken to preserve. Nothing errors anywhere along the way.
Both the CLI and the TUI now compare the wrapper's fingerprint to the target
profile and require an explicit override (--allow-fingerprint-mismatch, or a
confirmation in the TUI). `vault import --inspect` reports the backup's
fingerprint and encryption mode so the mismatch is visible before committing.
The CLI also stops deciding encryption mode by regex over the whole file: new
parseBackupWrapper reads the envelope, which is the structural question being
asked.
Tests: backups.test.ts (9 cases: filename parity, 0600, verbatim ciphertext,
mirror naming, mirror-failure reporting, interval throttling, CLI end-to-end)
plus foreign-import cases in cli.test.ts and tuiMenus.test.ts using a genuine
second profile rather than a doctored file. All mutation-verified: removing
each hook or guard turns the matching tests red.
