T
thePR0M3TH3ANandClaude Opus 5 2d27b5aaa9 Assert optInt's three edges and the path guard's positive case
Both checks could only be observed failing, so both could have been quietly
inverted.

`resolveWithinProfile` is `target !== root && !target.startsWith(root + "/")`.
Turn that `&&` into `||` and every path except the profile root itself is
refused — which the traversal cases could not see, because they expect a
refusal either way. A check that refuses everything is not a working check,
so the test now writes to a legitimate path inside the profile and confirms
the file lands there.

`optInt` guards length, period, digits, index, delay and the history target,
and each of its three clauses was unasserted: a non-integer (1.5), a negative,
and — the one that matters for the boundary — zero, which is NOT negative and
must stay accepted. `n < 0` quietly becoming `n <= 0` would reject a clipboard
delay of 0 and a derivation index of 0, both real choices.

Records one thing found on the way and deliberately not fixed here: a nested
export path answers 500 rather than a refusal naming the missing directory.

# SeedPass TODO
This file tracks the remaining work from the latest bug search and security evaluation.
## Entropy audit (2026-07-31)
[`docs/entropy_audit_2026-07-31.md`](docs/entropy_audit_2026-07-31.md) — RNG and
randomness-integration audit. **No predictable-fallback defect:** every non-deterministic secret
uses `os.urandom` / `secrets`, and the `random` module is not imported anywhere in non-test source.
**Read the compatibility constraint in that document before touching
`core/password_generation.py`.** Passwords are never stored — they are re-derived on demand from
`(seed, index, length, policy, gen_version)`. Entries now carry `gen_version`, and an absent field
means v1. **The rule is permanent: never alter the output of a version that already exists in the
wild.** v1 is frozen; a fix that changes derivation goes into a new version, never into an old one.
`src/tests/test_entropy_integrity.py` enforces this with 18 v1 vectors — a failure there is never
"update the expected value".
- [x] **M4 (done)** — v1 password vectors frozen, plus fail-closed RNG tests, in
`src/tests/test_entropy_integrity.py` (26 tests, inside the `--determinism-only` CI gate).
18 vectors cover every policy and both sides of the 32-byte stream-wrap boundary.
Mutation-verified: removing `_balance_distribution` (M1), altering the `DeterministicStream`
wrap (M3) and changing the character mapping (M2) each turn all 18 red; adding a
hash-of-timestamp fallback to `generate_bip85_seed` turns the fail-closed test red.
**M1/M2/M3 are now safe to attempt.**
- [x] **L1 (done)** — deleted the dead HKDF block in `_derive_password_entropy`, dropped the three
now-unused imports (`HKDF`, `hashes`, `default_backend`), and corrected the docstrings that
named HKDF instead of PBKDF2. Verified as a negative control: all 18 v1 vectors stayed green,
confirming the harness does not produce false alarms on behaviour-preserving edits.
- [x] **M1 / M2 / M3 (done)** — password generation is now versioned. `gen_version` defaults to 1
everywhere, so existing entries and every untouched caller keep deriving v1 byte-identically;
new password entries are stamped `gen_version: 2`. v2 drops the forced equal-quarters class
quota (M1), draws by rejection sampling (M2) from an unbounded HMAC-expanded stream (M3), and
enforces only the policy minima — choosing donor positions from classes that have a surplus,
so raising one minimum can no longer break another.
Measured at length 16 over 200 samples: v1 produced **1** distinct class composition, v2
produces **82**. Per-character entropy 6.42 → 6.53 bits against a 6.555 ceiling. Chi-square
96.1 (df=93) confirms the modulo bias is gone; lag-32 repeat rate sits within one standard
error of chance, confirming the repeating pad is gone.
- [ ] **Opt-in upgrade UX for existing entries** — a per-entry action that re-derives at v2, with a
confirmation making the consequence unmissable ("this changes the password; update it at the
site first"). Never bulk-migrate. Until this ships, existing entries stay on v1 by design.
- [x] **L2 (done)** — `generate_bip85_seed(words_num=...)` accepts 12 or 24 and rejects anything
else; threaded through `create_profile_from_generated_seed`. Default stays 12 so existing
profiles and callers are unaffected.
- [x] **L3 (done for the RNG path)** — `os.urandom(32)` moved outside the try block in
`generate_bip85_seed`, so no handler can stand between the entropy draw and the caller, and
the redundant duplicate `except Exception` is gone. A test asserts the `OSError` arrives as
the same object that was thrown, which is only true if nothing repackaged it.
- [x] **L4 (code fixes done)** — `torch/` temp filename now uses `randomBytes(8)`; the
`Math.random` value misnamed `nonce` in `relay-health.mjs` is now `probeSuffix` from
`randomBytes(6)`.
- [ ] **⚠️ Decision needed: `torch/_backups/` holds 5240 tracked files** across six dated
snapshots. Untracking is a large deletion, so it is not an audit side effect. Costs today:
duplicates every security grep hit, and bare `node --test` in `torch/` discovers them and
fails 18 tests from stale snapshot code (`npm test` uses explicit paths, so CI is unaffected).
Separately: `torch/` has no `test/` directory in the repo, so its `npm test` cannot run as
written.
- [x] **L5 (done)** — `dependency-audit.yml` generates and uploads a CycloneDX SBOM from
`requirements.lock`. Verified with the real tool: CycloneDX 1.6, 96 components, crypto chain
recorded at exact versions.
The remaining broad `except Exception` handlers in `password_generation.py` wrap deterministic
derivation with no RNG in it and re-raise rather than substituting; they belong to the Robustness
item further down, not to this audit.
## Security
- [ ] Complete checklist item #8 (Supply chain and release integrity):
- run one tagged release through `.github/workflows/release-integrity.yml` and link evidence in `docs/security_readiness_checklist.md`
- resolve or formally time-box/own the `GHSA-wj6h-64fc-37mp` exception (`docs/supply_chain_release_integrity.md`)
- enforce release/tag protections requiring `Release Integrity` + dependency audit checks
- publish maintainer/consumer verification runbook (checksum + cosign verification with expected issuer/identity) ✅ `docs/release_verification_runbook.md`
- [ ] Upgrade vulnerable runtime dependencies in lockfiles and packaging inputs:
- `aiohttp` -> `>=3.13.3`
- `cryptography` -> `>=46.0.5`
- `starlette` -> `>=0.49.1`
- `python-multipart` -> `>=0.0.22`
- `urllib3` -> `>=2.6.3`
- `pynacl` -> `>=1.6.2`
- `pillow` -> `>=12.1.1`
- `orjson`, `pyasn1`, `cbor2` and other `pip-audit` findings
- [ ] Regenerate `requirements.lock` after upgrades and re-run the full test suite.
- [ ] Re-run `pip-audit -r requirements.lock` and ensure zero actionable runtime vulnerabilities.
- [ ] Evaluate the `Crypto.*` imports in `src/seedpass/core/password_generation.py` and either:
- keep `pycryptodome` intentionally with explicit documentation, or
- migrate RSA generation to `cryptography` APIs.
## Robustness
- [ ] Replace broad `except Exception: pass` blocks with explicit exceptions + logging:
- `src/main.py`
- `src/seedpass/core/manager.py`
- `src/seedpass/core/menu_handler.py`
- [ ] Add telemetry-safe logs for swallowed error paths without exposing secrets.
- [ ] Harden startup/restore prompt flows against `EOFError` / cancellation loops:
- startup options (`Continue` / `Restore from backup`)
- restore-backup fingerprint/path prompts
- ensure graceful return-to-menu instead of process-level failure.
## Tests To Add
- [ ] Add deterministic tests for `derive_pgp_key(..., key_type="rsa")` covering:
- stable output across repeated runs
- key fingerprint format and validity
- [ ] Add API rate-limit tests for:
- per-client isolation
- window expiry behavior
- restart/reset behavior after `start_server()`
- [ ] Add API import tests for boundary conditions:
- exactly-at-limit upload size
- malformed multipart payload
- invalid JSON body for path-based import
- [ ] Add regression tests for manager notification/logging fallback paths currently guarded by broad exception handling.
## Documentation
- [ ] Document API import upload limit (`SEEDPASS_MAX_IMPORT_BYTES`) in user docs.
- [ ] Add a security maintenance section describing dependency-audit cadence and update policy.
## TypeScript port (`port/typescript-web-extension`)
Branch state as of 2026-08-17: core + CLI + interactive TUI are feature-complete
for daily use and cross-verified against Python on every change. What follows is
everything still open, in the order it should be tackled.
### Blockers before real secrets
- [~] **Independent security review — restated, since there is no third party.**
The point of the gate was catching what the author cannot see, which
needs an oracle that is not the author's judgement rather than another
person. Progress and what remains:
- [x] **Differential fuzzing vs Python** (`scripts/differential_fuzz.py`),
~10,000 cases over canonical JSON, password derivation, the sync
CRDT, index0, recovery shares, the semantic index and entry
hashing. Found a real defect: integral floats hash differently in
the two implementations, silently, which could make two clients
converge to different vaults. Also found — via mutation testing
turned on the fuzzer itself — that it could not reach the
tombstone or subject caps; fixed and re-verified.
- [x] **Wire the fuzzer and `cross_impl_check.py` into CI.** Done —
`.github/workflows/ts-parity.yml` runs both: `cross-implementation`
and `differential-fuzz` (three fixed seeds for bisectable
regressions, plus one exploratory seed derived from the run id so
the explored input space grows instead of freezing).
- [x] **Mutation testing in CI**, added 2026-08-19 as
`.github/workflows/mutation-testing.yml`. Weekly rather than
per-push: a full sweep is ~1 hour, and what it measures ("would
the suite notice if a security check broke?") drifts with test
and check changes, not with every commit. The script now exits 1
on a survivor and 2 on a target that generated no mutants, so
"not measured" cannot report as "clean". The job also fails if
any mutation is left in the tree at the end.
- [x] **Systematic mutation testing** of the security-critical modules
that have NO differential oracle because Python has no
equivalent: the session agent, the API HTTP layer, high-risk
session handling, sinks. Done 2026-08-19 via
`scripts/mutation_test.py`. All six targets sweep to ZERO
survivors: 132 mutants, 87 killed, 45 non-compiling. Re-run with
`.venv/bin/python scripts/mutation_test.py --target all`; it is
slow (~25s/mutant) so use `--offset/--limit` to slice it, and
never run it unattended — it writes deliberately broken security
code into the tree while it works, guarded by
`.mutation-test-running`.
It found real gaps rather than confirming the suite. The largest:
the high-risk expiry rule was written in two places that masked
each other's mutations, and one of the two was unreachable dead
code; a token's `kinds` restriction was entirely untested; the
API would delete the profile it was serving; `token-issue` would
mint a token for a profile the agent never held; an empty
high-risk factor was refused in both implementations and tested
in neither.
Two blind spots in the harness itself mattered as much as the
findings. It only mutated block-form guards, so every one-line
`if (cond) return ...;` — which is how most of the load-bearing
checks are written — was invisible; `src/highRisk.ts` generated
zero mutants and printed as a clean sweep. Both fixed: inline
guards are mutated, and a target that generates no mutants now
reports NOT MEASURED rather than passing silently.
- [ ] **DECISION TO RECORD: the API's settable config keys are a
superset of Python's.** Python's `update_config` allowlists 8
keys; the TypeScript route now allowlists 23, because it can set
the password-policy keys (`min_uppercase`, `exclude_ambiguous`
and friends) that this implementation honours and Python's API
does not expose. Matching Python exactly would mean deleting
working behaviour to reproduce a limitation, so the divergence is
deliberate — but it IS a divergence, and a client that sets a
policy key succeeds here and gets 400 there. Either widen
Python's allowlist or document the API surfaces as
non-identical; do not quietly leave it as an accident.
(Found 2026-08-19 during the adversarial pass.)
- [x] **Adversarial pass over TS-only surfaces**, framed as "what does
this trust?" rather than "is this correct?" — the framing that
finds trust-boundary bugs rather than logic bugs. Done
2026-08-19. What held up, so a later pass need not re-derive it:
- The agent socket bounds its input (512KB/line, 64 connections)
and validates op/cap/token/fingerprint/id/sink as strings
before comparing them.
- The exec allowlist is checked with `parseCommandSpec` on the
SAME array the spawn later parses, so there is no double-parse
gap. Every malformed `command` shape fails closed. Containment
is "which binary", never "what it does" — already documented at
the call site.
- CORS is exact-match against an allowlist that is empty by
default, echoes only allowlisted origins, and sets `Vary`.
- No path is ever built from ENTRY data; the one caller-supplied
path (document export) goes through `resolveWithinProfile`.
- Prototype-pollution-shaped writes (`obj[key] = value` over
parsed JSON) exist in the merge path, but merge input is
encrypted under the index key, so producing one requires the
seed already.
It found one real defect — the config API accepting any key and
any value, fixed in the same session — and one property worth
recording rather than unilaterally changing, below.
- [ ] **A nested export path answers 500 instead of a refusal.**
`POST /api/v1/entry/:id/document/export` with
`{"path": "exports/nested/secret.txt"}` fails with an opaque
"internal error": `atomicWrite` does not create parent
directories, by design. The path is caller-supplied, so this
should be a 400 naming the missing directory — a 500 tells the
caller the server broke when they simply named somewhere that
does not exist. Small; left out of the commit that found it
because that commit was about the traversal guard.
(Found 2026-08-19 during the mutation sweep.)
- [ ] **DECISION TO RECORD: an unencrypted portable backup is
unauthenticated, and import accepts it silently.** With
`encryption_mode: "none"` the payload is used verbatim; the
checksum that "verifies" it and the `fingerprint` that passes the
profile check both live in the same attacker-supplied file, so
they detect corruption and nothing else. A `seed-only` backup is
genuinely authenticated (Fernet HMAC under a seed-derived key —
only the seed holder could have produced it), and import treats
the two identically. `POST /api/v1/vault/import` REPLACES the
vault, so a user talked into restoring a hostile file gets an
attacker-chosen index whole: entries that look like theirs, with
stored values the attacker knows.
Python does exactly the same thing (`portable_backup.py`, the
`PortableMode.NONE` branch), so this is a shared design property
and NOT a port defect — which is also why it is recorded here
instead of being fixed on one side. Options, cheapest first:
report `encryption_mode` in the import response so the caller can
see what it got; require an explicit opt-in for `none` the way
the fingerprint mismatch already does; or drop the mode. Any of
them has to land in both implementations together.
(Found 2026-08-19 during the adversarial pass.)
Original note follows.
- [ ] **(superseded by the above) Independent security review of the TypeScript branch.** Review
strategy (decided 2026-08-18): two AI families plus vectors, because
they fail differently. (1) `/code-review ultra` — **blocked**: PR #989
spans main→port including beta's 150 commits (6795 files/720k lines),
over ultra's size limit; fallback options are a review-only PR
containing just the `js/` tree against main, or a narrower local-diff
target. (2) A GPT-family pass (Codex) over the four ranked targets in
the PR body, briefed to REFUTE the security claims in file comments,
not summarize them. (3) Third-party ground truth where possible: the
official BIP-85 spec vectors now run directly against the TS core
(test/bip85SpecVectors.test.ts; Python has had them all along), which
closes the both-implementations-agree-and-are-both-wrong hole for the
root derivation. Triage rule for findings: flagged by both families =
almost certainly real; flagged by one = verify against code, arbiter
is a reproduction test or the cross-impl suite, never the author's
opinion alone. No one but the
authoring agent has read this code. Two earlier review rounds on this
project each found criticals that self-review missed, so a green suite and
an author's sign-off are not evidence of much. Scope it to
`js/packages/core/src/crypto`, `js/packages/core/src/derive`, and
`js/packages/cli/src/agent.ts` first: a derivation bug does not throw, it
quietly produces a secret that cannot be recovered. Blocks the merge below.
- [x] **(done 2026-08-17/18) Fix the findings from the 2026-08-17
self-review** (next section) — all ten closed, plus all seven findings
from the 2026-08-18 independent audit (`js/SECURITY_AUDIT.md`). The
branch is ready to hand to an outside reviewer: their time now goes on
what an author cannot see.
### Findings from the 2026-08-17 self-review
Found by reading and probing, not by the suite — all 128 CLI tests passed
before and after each was confirmed. Ordered by severity.
- [x] **(fixed 2026-08-17)** **The agent can be left holding a parent seed
forever, after reporting failure.** `AgentDaemon.handle`'s `put` writes to `this.held` *before*
awaiting the audit append. A non-numeric `ttl` makes `expiresAt` NaN; the
audit write then throws on the non-finite number, so the caller is told
the unlock failed — but the seed is resident, `expire()`'s
`held.expiresAt <= now` is false forever, and no audit record exists
saying the vault was ever unlocked. Confirmed: `owner-mnemonic` returned
the full phrase 3.5s after a "failed" put on an agent with a 1s TTL.
Fix: validate `ttl`/`uses`/`expires_at` as finite positive integers at the
daemon boundary, and order every op so state is committed only after its
audit record lands. The CLI's `parseIntOption` already blocks this path,
which is exactly why the daemon must not rely on it — `agent.ts:1-22`
states the CLI is untrusted, and the browser extension will be the next
thing speaking this protocol.
- [x] **(fixed 2026-08-17)** **A `use`-scoped token holder can kill the agent
and drop every held seed.** `stdinSink` writes to `child.stdin` with no `error` listener, so a
command that exits before draining stdin raises an unhandled EPIPE.
Confirmed as an uncaught exception inside the agent process via a
`use-sink` request naming `/bin/true`; `main.ts` installs no
`uncaughtException` handler, so the real `agent start` process exits.
The exec allowlist does not help — any allowlisted command that exits
early does it. This is the least-privileged principal in the model taking
down the enforcement point. Fix: handle `stdin` errors the way
`feedClipboardTool` already does, and treat EPIPE as a delivery failure.
- [x] **(fixed 2026-08-17)** **Secrets sent to the clipboard are never cleared.** Python's
`copy_to_clipboard(text, timeout)` starts a timer and clears the clipboard
if the value is unchanged; the TypeScript `clipboardSink` just writes and
returns. `clipboard_clear_delay: 45` is in the default config, is
settable, and is read by nothing. This makes TUI **Secret Mode** — whose
entire purpose is to route secrets away from the screen — strictly less
safe than Python's, because it parks them on a session-wide clipboard
indefinitely.
- [x] **(fixed 2026-08-17)** **`kdf_iterations` is inert.** Settings displays it, stores it, and tells
the user "use Change password to re-wrap this profile's seed at the new
strength". `changePassword` takes an `iterations` parameter and the TUI
never passes it, and `createProfile` hardcodes
`DEFAULT_PBKDF2_ITERATIONS`. Raising it changes nothing anywhere. Either
wire it through both paths or remove the setting — a security control that
silently does nothing is worse than an absent one.
- [x] **(fixed 2026-08-17)** **`inactivity_timeout` is inert.** Stored, displayed, settable as Settings
item 12, enforced nowhere. Python's TUI locks the vault after it lapses;
the TypeScript TUI leaves an unattended terminal unlocked indefinitely.
- [x] **(fixed 2026-08-17)** **TUI file exports do not get the 0600 they claim.** `menus.ts` writes
document exports, database exports and the 2FA export with
`writeFile(..., {mode: 0o600})`. `mode` applies only at creation, so
writing over an existing 0644 file leaves it 0644 — verified. The 2FA
export is every TOTP secret in the vault in plaintext, and its comment
asserts the 0600. The CLI already does this correctly with `atomicWrite`
(fresh inode + rename, symlink-safe) and explains why; the TUI regressed
it. The TUI exports also silently overwrite, where the CLI requires
`--overwrite`.
- [x] **(fixed 2026-08-17)** **Audit-log truncation detection is defeated by deleting one more file.**
`AuditLog.verify` skips the count check entirely when `audit.log.head` is
absent, so removing the head and truncating the log verifies clean. The
head sits beside the log with the same permissions, so anyone who can
alter one can remove the other. The doc comment claims the head "pins the
expected length" against exactly this attack. Either require the head once
the log exists, or keep it somewhere the log's writer cannot reach.
- [x] **(fixed 2026-08-17)** **Unvalidated token constraint shapes.** `token-issue` casts `kinds` and
`scopes` without checking they are arrays. `kinds: "totp"` makes
`Array.includes` become `String.includes`, turning an exact kind match into
a substring match — inert today only because no SeedPass kind is a
substring of another. `scopes: "reveal"` throws a raw TypeError back to
the caller. Owner-gated, so this is hardening, not a live hole.
- [x] **(fixed 2026-08-17)** **Dead code that reads as a control.** `authorize()`'s `if (entry)` branch
is never reached (both call sites omit the argument; the real check is
`tokenMaySee`), and `sinkEnv`'s `FORBIDDEN_ENV` delete loop runs against an
allowlist that never contains those keys. Both look like defenses on
inspection. Remove them or make them load-bearing.
- [x] **(resolved 2026-08-17: confirmed deliberate, documented in authorize())** **A denied entry lookup still burns a token use.** `resolveForToken`
consumes a use at pre-auth, before the entry is known, so probing for
non-existent ids exhausts a token. That ordering is deliberate
anti-enumeration; confirm it is the trade wanted and write it down.
### Findings from the 2026-08-18 independent audit
Full report: [`js/SECURITY_AUDIT.md`](js/SECURITY_AUDIT.md) (Fable 5, line-by-line read
of every non-test source file at `e9d8908`). Verdict: no criticals or highs. This is one
AI family; the GPT-family pass in the blocker above is still outstanding and is what makes
the review independent in the sense that matters.
- [x] **(fixed 2026-08-18) M-2 — the profile config's password policy was ignored.**
Python bases derivation on `config_manager.get_password_policy()` and merges the
entry's `policy` block over it; the port merged the entry block over hardcoded
defaults and never read the config. Any profile with a non-default policy therefore
derived **different passwords** in TS than in Python, for every entry — reaching the
user as a wrong password, i.e. as data loss, with nothing failing anywhere.
`materializeSecret` now takes a `basePolicy`; the CLI, the agent and the TUI all
supply the profile config's policy, the TUI through a `sessionSecret` helper so no
menu path can omit it. Evidence:
`js/packages/cli/test/passwordPolicy.test.ts`, four cases against Python-computed
values, each also asserted unequal to the pre-fix output; mutation-verified (drop
`basePolicy` from the merge and all four go red).
- [x] **(fixed 2026-08-19) M-1 — restore could return a stale snapshot when two syncs
landed in the same second.** Manifests now carry `published_ms`, a monotonic
publication timestamp inside the signed JSON, and both implementations order by it.
Python additionally stopped delegating "which snapshot is newest" to the relay (it
asked for `limit(1)` and restored whatever came back). Backwards compatible: a
manifest without the field orders at the start of its `created_at` second. The nostr
CLI test went from ~1-in-4 failures to 6/6 clean runs.
**Found while fixing:** Python's `publish_delta` republishes the manifest and needed
the field too (without it the manifest carrying the newest `delta_since` sorted below
the snapshot it superseded, so readers fetched deltas from a stale watermark), and
raising the fetch limit turned a vestigial fallback loop into a live downgrade path —
now it skips relay noise but refuses to reach past the newest manifest that parses.
- [x] **(mitigated 2026-08-19) L-1 — BIP-85 app-32 is shared across password, SSH and PGP.**
Detection shipped in both implementations (`findDerivationCollisions` /
`find_derivation_collisions`), wired into import, `--inspect`, restore's merge, the
TUI, and a new `util check-derivation`. The lead test in each derives the keys and
compares bytes, so the claim is verified rather than asserted.
**The derivation change is deliberately deferred**, see the v2 design below.
- [x] **(ported 2026-08-19) index0/atlas.** The per-vault activity ledger is
now computed rather than carried verbatim: events are appended on every
mutation from all three surfaces, checkpoints and canonical views
rebuild, and `mergeIndexPayloads` merges both sides by default (it used
to keep the local block, so a restore discarded the remote's history).
Hashes and merge results are byte-identical to Python's, verified
against fixtures and end to end on a live vault.
**Two Python quirks are replicated on purpose** — `str(None)` == "None"
in required fields, and a stored integrity_hash is preserved even when
it disagrees — because diverging would change which events exist, not
just how they hash. Both are documented at the code.
**One deliberate design difference:** events are derived by diffing at
the mutation funnel rather than emitted per call site, because a
call-site emitter can be forgotten and a silently incomplete ledger
reads as "nothing happened".
- [x] **(ported 2026-08-19) Agent job profiles and recovery split.** Shares
interoperate in both directions, verified on a live parent-seed split.
Job profiles bind to a policy stamp byte-compatible with Python's
(including `ensure_ascii`). Drill logs are HMAC-chained like the audit
log. See the recovery-split security finding above.
**Every Python API endpoint now has a TypeScript equivalent.**
- [x] **(ported 2026-08-19) High-risk partitions and approval gates.** Both
file formats byte-compatible with Python and verified in both
directions. The unlock session diverges deliberately — see the security
finding above. `agent high-risk factor-set/status/unlock/lock/migrate`,
`agent approval issue/list/revoke`, and the /api/v1/high-risk routes.
- [x] **(surfaced 2026-08-19) L-2 / L-3 — merge-level loss that is silent rather than
wrong.** Both implementations gained an optional `MergeReport`: same-id conflicts
(naming the kept and discarded entries) and a count of tombstones evicted at the
retention cap. `nostr restore` reports both. The resolution itself is unchanged —
it is frozen for parity — and the collector is write-only, asserted in both
implementations, because if observing could change the outcome it would be a
divergence rather than an observation.
**Found while fixing:** Python's `merge_index_payloads` mutated its `current`
argument (shallow copy sharing the nested entries dict), and an existing idempotency
test was passing only because of that aliasing.
### L-1 v2 derivation: designed, deliberately not yet implemented
Domain-separate the three app-32 uses so `ssh@N`, `pgp@N` and `password@N` stop
sharing key material. Sketch, for whoever picks this up:
- Keep v1 exactly as it is, forever — existing SSH keys are on servers and in
forges, existing PGP keys are published. Nothing already derived may change.
- Add `derivation_version` to ssh/pgp entries, absent meaning 1, exactly as
`gen_version` works for passwords. New entries are stamped 2.
- v2 takes the app-32 entropy and applies one HMAC-SHA256 step with a
kind-specific info string (`seedpass:v2:ssh`, `seedpass:v2:pgp`,
`seedpass:v2:password`). Prefer this over new BIP-85 app numbers, which risk
colliding with future registrations.
- Land it in both implementations in one change, with cross-impl fixtures, and
an opt-in per-entry upgrade action — never a bulk migration. The same
"this changes the key; rotate it at the server first" confirmation the
password v2 upgrade needs.
**Sequencing:** this is a new derivation path, and this project's own rule is
that a derivation bug does not throw — it quietly produces a secret that
cannot be recovered. Adding one immediately before the first outside review
inverts the point of the review. Do it after.
- [x] **(fixed 2026-08-18) L-4 — inert settings, and the unported subsystem behind them.**
`additional_backup_path` was stored, confirmed by the TUI ("Additional backups will
be written to X") and used by nothing — false assurance in a disaster-recovery
feature. The cause was bigger than the setting: Python's `BackupManager` was not
ported at all, so `backup_interval` was dead for the same reason. New
`js/packages/cli/src/backups.ts` ports the write side — every committed mutation
snapshots the encrypted index to `<profile>/backups/entries_db_backup_<ts>.json.enc`
at 0600 and mirrors it to the configured second location as
`<fingerprint>_<name>`, filenames matching Python byte for byte so both
implementations share one backup directory. Two documented deviations: the interval
throttle 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 leave `backup_interval` inert for CLI use), and a failed mirror is surfaced
rather than swallowed. Quick Unlock stays in the menu for item-order parity but now
says it is unimplemented — in Python the flag never changed unlocking either, it
writes an audit entry and raises a security finding.
**Not ported:** `restore_latest_backup` (nothing in the TUI offers it; `vault import`
and `nostr restore` cover recovery), and `nostr_max_retries` / `nostr_retry_delay`
remain stored-but-unused.
- [x] **(resolved 2026-08-18) L-5 — `label_regex` is unanchored.** Left as-is deliberately:
Python matches with `re.search`, so anchoring the TS side alone would make one token
mean two different things depending on which implementation holds it, and would
silently narrow every token already issued. Now stated in `--label-regex` help,
reported as `capabilities().tokens.label_regex_semantics`, explained at the
enforcement point, recorded in `docs/typescript_port_compatibility_matrix.md`, and
pinned by tests asserting an unanchored token sees BOTH `prod` and `not-prod-db`.
- [x] **(documented 2026-08-18) L-6 — exec allowlist covers the command word, not argv.**
The token holder writes the arguments and the child gets the secret in its
environment, so an allowlisted binary with an output-file or network flag returns the
secret to its caller. Documented in help, `capabilities()`, and at the check itself.
Argument-level containment means allowlisting full argv templates instead of command
words — a token-format change that has to land in both implementations together, so
it stays a backlog item rather than a quiet divergence.
- [x] **(fixed 2026-08-18) L-7 — daemon `put` accepted any string as a fingerprint.**
Now requires 16 uppercase hex *and* that the fingerprint belongs to the supplied
seed. Ordered after the ttl check on purpose: deriving a fingerprint runs the BIP-39
KDF, and a malformed ttl should not pay for it.
- [x] **(fixed 2026-08-18) L-8 — plaintext backup import was not bound to a profile.**
A seed-only backup is implicitly seed-bound; 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 differs from what the backup was taken to preserve, with nothing
erroring. CLI and TUI now compare the wrapper's fingerprint to the target 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. The
CLI also stops deciding encryption mode by regex over the raw file —
`parseBackupWrapper` reads the envelope instead.
### Cutover
- [ ] Fold the CLI bundle's `.sha256` into the `release-integrity` signing
workflow (the remaining item of cutover gate 6).
- [ ] Merge to `main` and move the Python implementation to `legacy/`. Blocked
by the independent review above. **Merge-day checklist** (do these in
the same window, so main never advertises a stale product):
- [ ] **README rewrite, TS-first.** Install = the `seedpass-js` bundle;
features/architecture describe the TypeScript implementation; the
Python content moves to `legacy/README.md` with a pointer. The 🚧
bridge section added 2026-08-18 comes out (it exists precisely
because the rewrite would have been premature before review).
- [ ] **Landing page (`landing/`).** Install command switches off the
Python `install.sh` (or install.sh itself learns to install the TS
bundle); features/architecture copy updated; main/beta branch toggle
reconsidered (post-cleanup there is one line of development); drop
the `_pgbackup`/`_pginfo` Pinegrow artifacts. Verify where the live
site deploys from before assuming edits take effect.
- [ ] **Docs triage.** Python-era planning docs (the 14 bannered
2026-08-18: tui_v2/v3, index0/atlas, semantic) move under
`docs/legacy/` or keep their banners; living docs (vault/identity
spec, migration guide, security model, cutover plan) stay top-level;
`docs/README.md`/index updated to say which is which.
- [ ] **Branch/repo hygiene.** Fast-forward or delete `beta` (it is fully
contained in the merged history); revisit `dependabot.yml` (its pip
entries target the retiring Python deps); CHANGELOG entry for the
cutover.
- [ ] **CI.** `python-ci`/`tests`/`briefcase` workflows follow the Python
code to `legacy/` (or are scoped down); `ts-parity` and
`release-integrity` become the primary gates.
### Ported on 2026-08-19
- [x] **CLI gap closure** — `vault stats`, `vault change-password`,
`vault reveal-parent-seed`, `entry export-totp`, `config
toggle-secret-mode`, `config toggle-offline`, `api stop`. Passwords and
tokens come from the environment, never argv. `reveal-parent-seed`
follows `fingerprint create`'s egress rule: it refuses to print into a
pipe.
- [x] **QR codes in the TUI** — byte mode, versions 1-40, all four EC levels,
zero dependencies. The block-structure table was extracted
programmatically from the reference library rather than transcribed, and
the tests compare every module against it. One documented divergence:
mask SELECTION, because the reference scores candidates with their
format modules blanked (a symbol that is not legal); all eight masks are
valid, so the tests pin the mask and check the selection rule
separately. Secret Mode suppresses the code — a QR is the secret in a
form a camera reads across a room.
- [x] **Semantic (retrieval) index** — it was never vector search; it is
Jaccard overlap over tokenized metadata, which is why it was portable.
Ported to core, the CLI (`semantic build/status/search`) and the API.
**Two Python defects found and fixed while porting:** the index wrote
stored secrets to a plaintext 0664 file beside the encrypted vault, and
entry 0 — the first entry any profile creates — was silently
unsearchable. See the security note below.
### Security note: the semantic index leaked secrets (fixed 2026-08-19)
`SemanticIndex._extract_text` appended a `key_value` entry's `value` — the
stored secret — and `build()` wrote it to `semantic_index/records.json` in the
clear, plus a tokenized copy that leaked it just as well. The file was created
at the process umask (0664 on a default install), next to a vault that is
encrypted and 0600. Anything able to read the profile directory — a backup, a
sync client, another user on a shared machine — obtained the secret without
the master password.
Exposure is limited to profiles that actually built an index (it is opt-in and
off by default), but **any such index on disk still contains the secrets**:
the fix does not rewrite existing files. `MODEL_ID` is bumped to
`seedpass-token-overlap-v2` so a stale index is identifiable — `semantic
status` reporting v1 means "rebuild this, it holds secrets".
- [x] **(done 2026-08-19) Stale index files are deleted on first touch.**
Both implementations check the manifest's `model_id` whenever they read
an index, and remove records + manifest if it predates the fix, so the
plaintext does not sit there waiting for a user to notice a version
string. Safe because the index is a derived cache rebuilt in
milliseconds. A manifest that cannot be read is NOT treated as stale —
"cannot tell" must not mean "delete it", or a corrupt-manifest read
would throw away a good index.
### Security finding: recovery-split shares were derived from the secret (fixed 2026-08-19)
`agent_recovery._coef` derived every polynomial coefficient by HMAC-ing the
secret, so the whole share set was a deterministic function of it. Shamir's
defining property is that a sub-threshold set of shares is
information-theoretically independent of the secret — deriving the
coefficients from the secret destroys it, because a single share becomes an
offline verifier: guess a secret, re-run the split, compare. Demonstrated
recovering `hunter2` from one share of five at threshold three.
Second consequence: re-splitting produced byte-identical shares, so a leaked
share could never be rotated out without changing the secret itself.
Fixed by drawing coefficients from `secrets`, hoisted out of the per-share
loop (they had been recomputed per share, which only worked because they were
deterministic). **The share format is unchanged and `recover_secret` is
untouched**, so old shares keep recovering and both implementations
interoperate — a real security property at zero interop cost.
- [ ] **Consider re-splitting any secrets shared before this fix.** Old shares
still recover correctly, so nothing is broken; but shares generated by
the old code remain a guessing oracle for whoever holds one, and are not
rotatable. Only worth acting on where a share may have been exposed, or
where the secret has low entropy.
### Security finding: Python's high-risk unlock puts the partition key on disk
Found 2026-08-19 while porting the feature, and verified empirically.
`agent_high_risk_unlock.json` records the live session's `partition_key_tag`,
and `high_risk_partition_store._fernet_for_tag` derives the partition file's
encryption key from exactly that value. So while a session is live, the
high-risk partition decrypts from disk alone with **no factor**, for anything
that can read `APP_DIR` — and the session file lives in the same directory as
the key envelope, so being able to read one implies being able to read the
other.
That is the guarantee the partition exists to provide: ssh/pgp/seed/nostr
entries are the kinds judged to need a SECOND factor beyond the master
password, and during an unlock they effectively need none.
It is inherent to on-disk session state in a CLI with no resident process:
"unlocked for a TTL without re-supplying the factor" means the key must be
recoverable by the next process, and here that is the filesystem. Encrypting
the session under the master password or the seed does not help — then the
password alone reaches the partition, which is the thing the second factor is
supposed to prevent.
`grant_high_risk_unlock` now documents this at the point it happens. The
TypeScript port keeps the tag in the session agent's memory instead and never
writes it (asserted by a test that scans every file in the app directory).
- [ ] **Decide the Python fix.** Two real options, both product decisions:
(a) drop the session model and require the factor per operation, or
(b) give Python a resident agent for this (the TS agent already is one).
Interim guidance is in the docstring: short TTLs, `high-risk-lock` when
finished, treat read access to APP_DIR as equivalent to holding the
factor.
### Unbuilt milestones
- [ ] **Milestone 6 (static/PWA web app)** and **Milestone 7 (browser
extension)** of `docs/typescript_web_extension_port_plan.md` are not
started — `js/packages/` holds `core`, `cli` and `test-vectors` only. The
branch is named for a web extension that does not exist yet; the CLI was
the proving ground for the core.
**Transport is no longer a blocker for this:** the API is ported, so an
extension has something to talk to. The remaining question is whether a
browser should reach the API over loopback at all, or whether the
extension should embed the core directly — decide before starting M7.
- [x] **(done 2026-08-19) The `api` surface is ported.** `seedpass-js api
start` serves /api/v1 on `node:http` with no framework — the CLI ships
one audited bundle with an empty production dependency list, and a web
framework in a seed-holding process would be the largest supply-chain
change in the project. Loopback unless `--allow-remote`; bearer token
printed once; routes that produce plaintext also require the master
password header; body cap, rate limit, and a tighter unlock-attempt
budget that returns 429 even for the right password once spent.
Verified end to end that Python, the TS CLI and the TS API derive the
same secret for the same entry. Routes belonging to unported subsystems
answer 501 naming the feature, not 404.
- [ ] ~~Decide whether the `api` (FastAPI) surface gets a TypeScript port at
all.~~ (superseded by the above) It is currently excluded from cutover gate 5 as "a separate
surface, not vault behavior", and the session agent (unix socket, 0600,
scoped tokens) covers agent automation without binding a port — a smaller
attack surface for a process holding unlocked seeds. `src/seedpass/api.py`
is 2093 lines and much of it hangs off features that are deliberately not
ported (high-risk partitions, agent job profiles, recovery split,
semantic). A faithful port means porting those first; the genuinely useful
subset is entry CRUD, search, lock/unlock and config. Options: leave it
Python-only, port the subset, or drop it. Decide before the extension
lands, since the extension needs *some* transport.
## Shared vault/identity spec (BitLogin groundwork)
- [x] **(done 2026-08-18)** Entry-id allocation watermark — ids are never
reused after deletion; `_sync_meta.next_index`, merged as max, in both
implementations with cross-impl parity. The precondition for "account
#N" as a recovery coordinate.
- [x] **(done 2026-08-18)** `docs/seedpass_vault_identity_spec.md` — v1 draft
extracted from working code: canonicalization, containers, derivation
table, the two index namespaces, allocation rule, interop rules
(preservation, namespacing, no-translation-table, round-trip
conformance), capability profiles, sync/backup, and an honest gap
ledger.
- [x] **(done 2026-08-18)** Unknown-kind passthrough (spec §8.2/§12) — TS
parses unrecognized kinds as opaque records (verbatim, excluded from
typed operations, malformed KNOWN kinds still fail); CLI listing
redacts foreign fields as `has_*` and reveal refuses cleanly; Python
tolerance pinned by test. Discovered en route: Python backfills base
defaults on foreign records where TS carries verbatim — a benign but
real canonicalization divergence, now in the spec gap ledger, to align
before foreign kinds actually sync.
- [x] **(done 2026-08-18)** Round-trip conformance check as CI (spec §8.6) —
cross-impl Phase L: a vault holding a foreign record (unknown kind,
trap fields, nested data) plus an unknown top-level index key survives
Python→TS→Python read-modify-write byte-for-byte; allocation skips the
foreign id; TS refuses to reveal it. Landing it forced the
normalization decision: Python's legacy renames now skip unknown kinds
(they would have reinterpreted foreign data — verified: the old code
turns a foreign `blacklisted` string into our `archived` flag, and
Phase L catches it). 38/38 cross-impl checks.
## Post-BitLogin and backup/UX ideas (logged 2026-08-18)
- [ ] **Capsule unlock ("sign in with BitLogin")** — spec §11.1 added with
the flow and the two normative rules (independence: an unlocking key
must not derive from the vault it unlocks; rank: a managed identity
must never unlock the root that provisioned it). Implementation is
post-BitLogin by definition: it slots in as a fourth seed resolver
(env → agent → capsule → password) plus a capsule file format, zero
core-crypto changes. Scope first release to delegated org subtrees;
personal vaults keep password-primary with capsule as opt-in for
self-custodial keys.
- [ ] **Blossom server support for index backups** — store the encrypted
snapshot as a single content-addressed blob on N Blossom servers
(auth-signed by the existing app-1237 sync identity), with the relay
manifest pointing at blob hash + server list. Keeps relay sync as-is
(deltas + coordination, works today); Blossom removes the chunking
ceiling that big vaults (documents!) hit on relays. Needs: manifest
field tolerance check in both implementations, retention/mirror
policy, and the same metadata-leakage analysis as relays (a pubkey's
blob list is public).
- [x] **(phase 1 done 2026-08-18)** **`.seedpass` file extension** — CLI
`vault export <dir>` and the TUI database export generate
`seedpass-<fingerprint>-<date>.seedpass`; extensionless TUI input gets
the suffix; explicit paths are used exactly as typed (scripts
unaffected); imports never cared about extensions. Zero byte-format
change. Remaining (deliberately later): phase 2 format_version 2 with
a magic header (versioned, both implementations), and OS file
association + icon from `logo/svg/` (XDG MIME via install.sh, registry
via install.ps1) — installer work, after #34/#36.
## CI health (noticed 2026-08-18 while preparing PR #989)
- [x] **(addressed 2026-08-19) CI is now watched and the fuzzer runs in it.**
`scripts/differential_fuzz.py` is wired into ts-parity with three fixed
seeds (deterministic, bisectable) plus one derived from the run id, so
the explored input space grows over time. `cross_impl_check.py` was
already there — an earlier note in this file claiming otherwise was
wrong.
- [ ] **ts-parity was red for 33 straight runs** on an environment-coupling
bug local runs masked (`vault import --vault` demanded a default
profile; fixed in cf433e3 with a hermetic SEEDPASS_APP_DIR in the CLI
test harness). Standing lesson: CI results were never checked because
local suites were green — check the workflow dashboard when a branch
is long-lived.
- [x] **(diagnosed and mostly fixed 2026-08-19) Red checks on PR #989.**
Pulled the actual logs rather than guessing. Three distinct causes, not
one:
- **CI / dependency scan** — genuinely red for a good reason:
`pip-audit` found 100 known vulnerabilities across 15 packages,
including `cryptography` itself. **Fixed**: floors raised, lock and
`poetry.lock` regenerated, audit now clean. The stubborn one was
`starlette`, pinned `<0.48` for a FastAPI constraint that no longer
exists (fastapi 0.141 requires `>=0.46` unbounded), which had been
holding seven advisories open.
- **Tests, every OS and Python version** — `black --check` found 28
unformatted files, part pre-existing, part from this session.
**Fixed**, with fixtures regenerated afterwards to prove no hashed
value moved.
- **Installer Smoke, Windows only** — NOT fixed, and needs a decision.
`portalocker` pulls `pywin32` on Windows; `pip-compile` runs on Linux
and drops the Windows-only marker, so `pywin32` never reaches
`requirements.lock`. The Windows installer installs with
`--require-hashes`, which then refuses the unpinned transitive
`pywin32>=226`. Naming it in `src/requirements.txt` with a
`sys_platform == "win32"` marker does NOT work — pip-compile on Linux
drops it again — and hand-editing the lock is futile because four
workflows regenerate it.
- [ ] **Decide how to produce a multi-platform lock** (blocks Windows
installer smoke). Options: run `pip-compile` on a Windows runner and
commit a second `requirements-windows.lock`; move to a resolver that
does platform-independent locking (uv); or drop `--require-hashes` on
Windows, which trades supply-chain integrity for a green check and is
the wrong trade. Note this affects only the Python installer, which is
the implementation being retired.
