Mutation testing found `token.expires_at <= now` could become `<` with every test still passing. The suite checked well before and well after expiry, which cannot tell the two apart — so a token was free to be usable for one more request than it claimed, which is the wrong direction for a credential. The daemon now takes an injectable clock, so the boundary can be asserted exactly rather than raced against wall time: at T-1 the token works, at exactly T it is refused. Every expiry decision AND every expiry assignment goes through that clock — a token issued against real time while checked against test time would never expire, which would have made the test meaningless. The TOTP timestamp-skew window uses it too, since a clock that moved one but not the other is a difference no production path should have either. Also pins the owner capability: an empty or absent capability is refused, and so is one of the right length but wrong content — the latter proving the constant-time comparison is what rejects it rather than the length check. One survivor is now recorded as genuinely unkillable rather than chased. `!presented || !this.capability` cannot change behaviour when flipped to `&&`, because the length comparison below rejects an empty string either way. The harness learned a `mutation-equivalent:` marker that must carry a REASON, so future survivor lists mean "look at this" instead of "this again" — and the judgement stays re-checkable rather than merely trusted. The harness also gained `--offset`, so a long target is measured in foreground-sized slices. That is a safety property, not a convenience: this script writes broken security code into the working tree, and it must never run unattended alongside commits again. agent slice 1 (mutants 1-6): 100% of viable mutants caught.

seedpass-js
The SeedPass command-line interface, TypeScript port.
It reads and writes the same ~/.seedpass profiles as the Python
implementation — same derivations, same vault format, same Nostr sync — and
adds a session agent plus a scoped-token surface designed for AI agents and
automation.
Install
Requires Node.js 22 or newer.
# from a checkout
cd js && pnpm install && pnpm --filter @seedpass/cli build
node packages/cli/dist/seedpass-js.mjs --version
The build produces one self-contained file (dist/seedpass-js.mjs) plus a
.sha256 next to it. Copy it anywhere on your PATH; it has no runtime
dependencies beyond Node itself.
Quick start
export SEEDPASS_APP_DIR=~/.seedpass # omit to use the default
# Create a profile (mnemonic and password come from the environment,
# never from the command line)
export SEEDPASS_MNEMONIC="your twelve or twenty-four words"
export SEEDPASS_PASSWORD="your master password"
seedpass-js fingerprint add --name main
unset SEEDPASS_MNEMONIC # not needed again
# Unlock once per session through the agent
seedpass-js agent start &
seedpass-js vault unlock --ttl 900
seedpass-js entry add password github.com --length 20 --username you
seedpass-js entry reveal github.com
seedpass-js entry totp-codes
seedpass-js use github.com --clipboard
seedpass-js vault lock
Design: reference-first output
Default output never contains secret values. Entries are addressed by
reference (sp://entry/<id>), and secret-bearing fields are reported as
has_* flags:
$ seedpass-js entry get api-token
{ "id": "5", "ref": "sp://entry/5", "label": "api-token",
"kind": "key_value", "has_value": true, ... }
Plaintext leaves the vault only through commands that say so
(entry reveal, entry totp-codes, entry export-document,
util generate-password), or through a sink, which delivers a secret to its
destination without routing it through this process's output:
seedpass-js use api-token --exec ./deploy.sh # SEEDPASS_SECRET in the child env
seedpass-js use api-token --stdin-to "wc -c" # quote specs that contain flags
seedpass-js use api-token --clipboard
Scoped tokens for agents
An agent can be given a token that grants exactly what it needs and nothing else. Secrets are materialized inside the session agent, so the token holder never receives the seed and can never escalate to owner operations.
# As the owner:
seedpass-js agent token-issue --scope read use \
--kind key_value --label-regex '^api-' --uses 2 --ttl 600
# In the agent's process — no mnemonic, no password:
export SEEDPASS_TOKEN=<token>
seedpass-js entry list # metadata only
seedpass-js use api-token --exec ./deploy.sh # permitted
seedpass-js entry reveal api-token # denied: scope 'reveal' not granted
# Back as the owner — every grant, delivery and denial is recorded:
seedpass-js agent audit-verify
seedpass-js agent audit-tail -n 20
Environment
| Variable | Purpose |
|---|---|
SEEDPASS_APP_DIR |
Profile directory (default ~/.seedpass) |
SEEDPASS_MNEMONIC |
Parent seed; needed for profile creation, otherwise use the agent |
SEEDPASS_PASSWORD |
Master password, for fingerprint add and vault unlock |
SEEDPASS_TOKEN |
Scoped token; puts the CLI in token mode |
SEEDPASS_AGENT_SOCK |
Override the agent socket path |
SEEDPASS_SECRET |
Set by use --exec in the child process only |
Compatibility
Interoperability with the Python implementation is verified on every change
by scripts/cross_impl_check.py: each side opens the other's profiles,
backups round-trip, edits are mutually visible, conflict merges agree, and a
snapshot published by Python restores here with secrets intact. See
docs/typescript_port_compatibility_matrix.md.
Not yet ported: PGP RSA keys (not byte-reproducible; ed25519 is at parity),
and the semantic and api command groups.
