fix(core): zeroize the derived X25519 secret (#65 ) (#66 )

x25519_secret_from_seed derived the X25519 private scalar from the Ed25519 seed and returned it as a bare [u8; 32]. Because [u8; 32] is Copy with no Drop (and sha2's digest output likewise has no zeroize), the scalar, the SHA-512 digest, and the returned temporary were released without being scrubbed, leaving secret-derived material in freed memory. This is the same Copy-no-Drop class fixed for the raw seed in #41, on the derived secret. Return Zeroizing<[u8; 32]>, build the scalar directly into a zeroizing buffer so no bare secret local persists, and explicitly wipe the SHA-512 digest before it drops. Callers deref the result into crypto_box::SecretKey, which already scrubs its own copy. No behavior change: the derived scalar and all decryption output are byte-identical, covered by the existing ed25519_to_x25519_keypair_agrees and seal_open_round_trip_for_recipients tests. Stacked on #41 (#64).
fix(node): migrate node_seed pin caller to to_seed()

 For public-network use, make sure `GITLAWB_NODE` points to the node you want. The helper defaults to localhost for local development.

-### Full lifecycle against an iCaptcha-enforcing node
-
-Public nodes (e.g. `node.gitlawb.com`) require two things on writes:
-
-1. **RFC 9421 HTTP Signatures** — every write is signed by your identity key. `gl`
-   and the `git-remote-gitlawb` helper do this automatically. An old/unsigned CLI
-   fails with `401 not_an_agent`; `gl` will tell you to upgrade and register.
-2. **An iCaptcha proof** on the spam-gated writes (**repo create, fork, register**).
-   `gl` solves this for you: on the node's `403 icaptcha_proof_required` it reads the
-   `x-icaptcha-url` / `x-icaptcha-level` hints, requests a challenge, solves it
-   locally (arithmetic / algebra / sequence), and **retries the same signed request**
-   with the `x-icaptcha-proof` header — no manual steps, no env vars.
-
-```bash
-gl identity new                                   # create did:key identity
-gl register      --node https://node.gitlawb.com  # signed + auto-solves iCaptcha
-gl repo create memlawb --node https://node.gitlawb.com   # signed + auto-solves iCaptcha
-git push  origin2 main                            # origin2 = gitlawb://<your-did>/memlawb (signed)
-git clone gitlawb://<your-did>/memlawb            # public read, no proof needed
-gl doctor                                         # preflight: identity, node, version, iCaptcha
-```
-
-Notes:
-
- **`requesterId` is always your DID.** The proof's `sub` claim must equal the
-  authenticated signer; `gl`/helper set this automatically and the node enforces
-  `sub == authenticated DID` (so a proof minted for another identity is rejected).
- **Proofs are short-lived (~5 min TTL) and single-use.** If one expires between
-  solving and use, the client transparently solves a fresh one and retries.
- **What needs what:** create / fork / register are signed **and** iCaptcha-gated;
-  `git push` is **signed-only** (owner signature is the gate — no per-push challenge);
-  reads (clone / fetch / `repo info`) need no proof. A non-existent repo returns a
-  clear `404`, never a placeholder.
- **API-key iCaptcha deployments:** set `GITLAWB_ICAPTCHA_URL` to your iCaptcha
-  origin and `GITLAWB_ICAPTCHA_API_KEY` to its key. The client only talks to an
-  `https` origin whose host is allowlisted (that URL or the public default), and
-  sends the bearer token **only** to your configured origin — never to a URL a
-  node advertises — so a hostile node can't capture the key or redirect the solve.

-# Dependency allowlist for the `gitlawb-core` crate.
-#
-# gitlawb-core is the shared-primitives crate every consumer embeds (the `gl`
-# CLI, git-remote-gitlawb, the node daemon). It must stay lean so those
-# consumers do not inherit daemon-weight dependencies. This file is the source
-# of truth for the crates gitlawb-core's NORMAL (non-dev, non-build) transitive
-# dependency closure is allowed to contain. CI (`scripts/check-gitlawb-core-deps.sh`,
-# wired into the `core-deps-purity` job in .github/workflows/pr-checks.yml)
-# fails if gitlawb-core's tree contains any crate not listed here.
-#
-# The allowlist is exhaustive-by-construction: a NEW dependency reds CI whether
-# or not anyone thought to ban it, which a denylist cannot do.
-#
-# Measured in-workspace, so feature unification across the workspace can, in
-# rare cases, surface a crate here that gitlawb-core would not pull standalone.
-# An unexpected new entry is a prompt to check what pulled it in, not noise to
-# rubber-stamp.
-#
-# Regenerate (from repo root, after an INTENTIONAL dependency change):
-#   cargo tree -p gitlawb-core --edges normal --prefix none \
-#     | sed -E 's/ v[0-9].*$//' \
-#     | grep -v '^gitlawb-core$' \
-#     | sort -u
-# then paste the result below this header block. (The checker snapshots and
-# restores Cargo.lock; a manual regen may refresh it — `git checkout Cargo.lock`
-# afterward if you did not intend that.)
-#
-# Lines starting with `#` and blank lines are ignored by the checker.

-//! Push-delta object enumeration for the IPFS/Pinata pin path.
-//!
-//! The pin path needs the set of git objects to consider for pinning after a
-//! push. Historically both pin functions enumerated the *whole* repo
-//! (`git cat-file --batch-all-objects`) on every push, so cost scaled with
-//! repo size rather than push size (finding N16). This module computes the
-//! per-push *delta* instead — the objects a push introduced — and keeps the
-//! whole-repo lister for the reconciliation sweep and the fail-closed fallback.
-//!
-//! ## Correctness framing (do not confuse with the #84 withholding direction)
-//!
-//! The pin enumeration is part of the *exposure* set, not the withheld filter.
-//! On the *delta* path, narrowing per push only *shrinks* what is pinned, so it
-//! cannot create an under-withholding leak — the reachable-only withheld filter
-//! (`visibility_pack`) still subtracts from the smaller set we feed it. The only
-//! risk there is *under-pinning* (a durability gap) the sweep backstops.
-//!
-//! The *full-scan* path is different: `list_all_objects` includes dangling
-//! objects the reachable withheld set never classified, so subtracting that set
-//! is not enough — a dangling private blob would slip through (#99). The caller
-//! signals a full scan via [`PinCandidateSet::full_scan`] and must then apply
-//! the fail-closed blob filter (`visibility_pack::replicable_objects_fail_closed`)
-//! instead of the plain reachable-only subtraction.
-//!
-//! Because the pin candidate set needs only the OID *set* (never the per-path
-//! information the withheld classifier needs), `git rev-list --objects
-//! --no-object-names` is safe here. The "rev-list reports one path per object"
-//! trap from #84 applies only to `visibility_pack`'s per-path `ls-tree` walk.

-//! Behaviour is controlled by `ICAPTCHA_MODE`:

-//!   * `shadow`  — verify and log would-be rejections, but always allow.
-//!   * `enforce` — reject requests without a valid, sufficiently-strong proof.
-//!
-//! Config (env):
-//!   ICAPTCHA_MODE            off | shadow | enforce         (default off)

-//! Client for the iCaptcha proof-of-intelligence service.
-//!
-//! The node gates spam-prone writes (repo create / fork / register) behind an
-//! iCaptcha proof. This crate implements the *sanctioned client flow*: on a
-//! `403 icaptcha_proof_required`, request a challenge for the required level,
-//! solve the deterministic computational types locally, obtain the signed
-//! proof, and hand it back so the caller can retry the original signed request
-//! with the `x-icaptcha-proof` header.
-//!
-//! `requesterId` is always the caller's DID, so the proof's `sub` claim matches
-//! the authenticated signer (the node enforces `sub == authenticated DID`).
-//!
-//! Blocking HTTP (reqwest::blocking) so the git remote helper can use it
-//! directly; `gl` (async) calls it via `tokio::task::spawn_blocking`.

-## Hardening: owner-only push
-
-By default the node authenticates every `git-receive-pack` push (a valid RFC 9421
-`did:key` signature) but does **not** check that the pusher owns the repo, except
-on branches that are explicitly protected. Because `did:key` is self-certifying,
-any party can generate a key, derive its DID, sign, and push to an unprotected
-branch — authentication is not authorization.
-
-To require the authenticated pusher to be the repo owner on **every** branch, set:
-
-```bash
-GITLAWB_ENFORCE_OWNER_PUSH=true
-```
-
- **Default `false`** — preserves current behavior so live nodes are unaffected by
-  an upgrade. Turn it on once you're ready for owner-only writes.
- **When `true`** — a push whose authenticated DID is not the repo owner is
-  rejected (HTTP 403) before any ref update is applied. The owner is matched in
-  both the full `did:key:z6Mk…` form and its bare `z6Mk…` suffix.
- **Caution: this blocks every non-owner pusher, including your own delegated and
-  CI agents.** Push authorization is owner-only today — a UCAN `git/push`
-  capability is verified but not yet honored for authorization, so delegated keys
-  cannot push while this is on. Don't enable it until every identity that pushes
-  to your repos is the owner, or you'll lock out your own automation. Scoped
-  collaborator / UCAN-delegated push rights are a planned follow-up.

 ## Operational checklist

 | Concern | Recommendation |
Author	SHA1	Message	Date
beardthelion	9a46e8cbb7	fix(core): zeroize the derived X25519 secret (#65 ) (#66 ) x25519_secret_from_seed derived the X25519 private scalar from the Ed25519 seed and returned it as a bare [u8; 32]. Because [u8; 32] is Copy with no Drop (and sha2's digest output likewise has no zeroize), the scalar, the SHA-512 digest, and the returned temporary were released without being scrubbed, leaving secret-derived material in freed memory. This is the same Copy-no-Drop class fixed for the raw seed in #41, on the derived secret. Return Zeroizing<[u8; 32]>, build the scalar directly into a zeroizing buffer so no bare secret local persists, and explicitly wipe the SHA-512 digest before it drops. Callers deref the result into crypto_box::SecretKey, which already scrubs its own copy. No behavior change: the derived scalar and all decryption output are byte-identical, covered by the existing ed25519_to_x25519_keypair_agrees and seal_open_round_trip_for_recipients tests. Stacked on #41 (#64).	2026-06-23 22:05:56 +08:00
beardthelion	e4f5e87e0b	fix(node): migrate node_seed pin caller to to_seed() main grew a third seed_bytes() caller (repos.rs, from #40) after this branch was cut. Route it through to_seed() too: node_seed is moved into a long-lived tokio::spawn pin task, so the Zeroizing wrapper scrubs the copy when that task ends. encrypt_and_pin takes &[u8; 32]; the wrapper deref-coerces, so the call site is unchanged.	2026-06-22 12:14:40 -05:00

beardthelion	4f814459cc	test(core): pin to_seed's Zeroizing return type, drop duplicate round-trip The to_seed_is_sole_seed_accessor test was named for a compile-time property its body couldn't assert, and its from_seed -> DID check duplicated from_seed_round_trip. Replace it with a type-annotated binding that fails to compile if to_seed ever returns a bare [u8; 32] again, plus the determinism check, which is the only behavior it uniquely covered.	2026-06-22 11:52:38 -05:00
beardthelion	d45318281c	fix(core): route seed access through the zeroizing wrapper (#41 ) Remove Keypair::seed_bytes(), which returned a bare [u8; 32] copy of the Ed25519 private seed. Because [u8; 32] is Copy with no Drop, each caller's copy was released without being scrubbed, leaving secret key material in freed memory. The zeroizing accessor to_seed() -> Zeroizing<[u8; 32]> already existed beside it; this makes it the sole seed accessor and migrates the two in-crate callers (envelope open path and a crypto test) to it via deref coercion. No behavior change to envelope encryption: the derived X25519 secret is byte-identical, covered by the existing round-trip tests. Adds an identity test pinning to_seed() as the only seed accessor.	2026-06-19 22:01:08 -05:00
