fix(security): reject path traversal in repo_store local_path

Closes CodeQL alert #4 (Uncontrolled data used in path expression). Both `owner_did` and `repo_name` come from URL parameters and were used unsanitized to build a filesystem path, so a request like `/did:key:foo/../../../etc/passwd.git/info/refs` could escape the repos directory. Fix: - New `validate_owner_did` and `validate_repo_name` enforce a strict allowlist before path construction (alphanumeric + `: . _ -` for DIDs; alphanumeric + `. _ -` for repo names; rejects empty, `..`, leading `.` or `-`, slashes, backslashes, null bytes, overlong inputs). - `RepoStore::local_path` now returns `Result<…>` and the 5 callers propagate the error. - Defence in depth: even after the allowlist passes, the joined path is checked to still be rooted at `repos_dir`. - 17 unit tests cover normal DIDs/repo names plus every malicious shape (`..`, `/`, `\`, leading dot/dash, null byte, overlong, did:web with dots).

-## Before you request review
-
- [ ] Scope is one logical change; no unrelated churn
- [ ] `cargo test --workspace` passes locally
- [ ] New behavior is covered by tests (required for fixes)
- [ ] `cargo fmt --all` and `cargo clippy --workspace --all-targets -- -D warnings` are clean
- [ ] Commit titles use Conventional Commits (`feat(...)`, `fix(...)`, `docs(...)`)
- [ ] Docs / `.env.example` updated if behavior or config changed (or N/A)
- [ ] Checked existing PRs so this isn't a duplicate
-
-## Protocol & signing impact
-
-<!-- Delete this block if your change doesn't touch the protocol. -->
-
- [ ] Touches DID / `did:key`, Ed25519 / RFC 9421 signatures, UCAN, ref certs, or P2P wire formats
- [ ] Discussed in an issue before implementation
- [ ] Backward-compatible with existing nodes and previously signed history

 4. **Conventional commits.** Use `feat:`, `fix:`, `docs:`, `refactor:`, `test:`, `chore:`. Releases are automated by [release-please](https://github.com/googleapis/release-please) — your commit prefixes drive the next version bump.
 5. **Format and lint.** Run `cargo fmt --all` and `cargo clippy --workspace --all-targets -- -D warnings` before submitting. CI will reject anything that fails these.

-## What gets merged, what gets closed
-
-We welcome contributions from humans and agents alike. To keep review sustainable, PRs are
-expected to clear a basic quality bar:
-
- **Link an issue.** Bug fixes and features should reference an issue (`Closes #123`). For
-  protocol-level changes (identity, signatures, UCAN, ref certs, wire formats), open the
-  issue *before* writing code.
- **One change per PR.** Unrelated churn slows review and gets sent back.
- **Tests and a green pipeline.** New behavior needs tests; `cargo fmt`, `cargo clippy`,
-  and the full CI suite must pass.
- **A real description.** Say what changes and why. "Update code" is not a description.
-
-A triage bot labels PRs that are missing these and leaves a short note. Nothing is closed
-automatically while you're engaging. A flagged PR still missing a description after 14 days of
-inactivity gets a stale warning, and is closed 7 days later if still untouched. A missing issue
-link alone never triggers closure; that label stays advisory. Closed PRs can be reopened at any
-time once updated.

 ## Development environment

 **Requirements:**
- Rust stable (≥ 1.91) — install via [rustup](https://rustup.rs)
+- Rust stable (≥ 1.85) — install via [rustup](https://rustup.rs)
 - PostgreSQL — required for the node. Use the bundled `docker-compose.yml` for local dev.
 - Docker (optional, for full-stack local testing)

-**Decentralized git infrastructure for developers, AI agents, and app delivery.**
+**Decentralized git for AI agents and developers.** Run your own node, host repos under your own DID, and connect to the gitlawb network.

-Gitlawb Node is the open-source node software behind the Gitlawb network. It lets anyone run a self-hosted node, publish repositories under a DID, sign writes with Ed25519 HTTP signatures, replicate git activity across peers, and move toward a resilient app-delivery network where code and build assets can be served closer to users.
+This repository contains the open-source node software:

-Gitlawb is not trying to be only “another git host.” The long-term direction is:
-
-```txt
-Decentralized GitHub
-+ signed agent-native workflows
-+ resilient repo replication
-+ CDN-style app/code delivery
-```
-
-The mission is simple: once code is pushed to the network, it should not disappear because one server went down.
+- `gitlawb-node` — Axum HTTP server, git smart-HTTP, libp2p gossip, optional S3-compatible storage
+- `gl` — CLI for identity, repos, PRs, MCP server
+- `git-remote-gitlawb` — `git remote helper` for `gitlawb://` URLs
+- `gitlawb-core` — shared crypto primitives (DID, CID, HTTP signatures, UCAN)

 ---

-## What is in this repository?
+## Quickstart

-This is a Rust workspace with four crates:
-
-| Crate | Purpose |
-|---|---|
-| `gitlawb-node` | The node daemon: Axum HTTP server, git smart-HTTP, Postgres metadata, libp2p gossip, optional S3/Tigris/IPFS/Arweave/Base PoS hooks. |
-| `gl` | The Gitlawb CLI for identity, repos, issues, PRs, bounties, tasks, peers, node status, MCP, and setup flows. |
-| `git-remote-gitlawb` | Git remote helper for `gitlawb://` URLs, so normal `git clone`, `git fetch`, and `git push` can talk to Gitlawb nodes. |
-| `gitlawb-core` | Shared primitives: Ed25519 identities, `did:key`, CIDs, RFC 9421 HTTP signatures, certificates, and UCAN tokens. |
-
---
-
-## Why Gitlawb Nodes?
-
-Most git hosting today depends on a small number of centralized platforms. Gitlawb Nodes are designed for a different model:
-
- **Own your identity** — every user, agent, and node is an Ed25519 keypair represented as `did:key:z6Mk...`.
- **Signed writes by default** — write requests use RFC 9421 HTTP Signatures instead of passwords.
- **Git-native transport** — repositories are still real git repositories served over smart HTTP.
- **Agent-native workflows** — the `gl` CLI and MCP server expose repo, issue, task, PR, and UCAN flows to AI agents.
- **Peer-aware delivery** — nodes can announce, discover, gossip, and sync with each other.
- **App CDN direction** — the network can evolve from decentralized code storage into code + asset + app delivery.
-
---
-
-## Current status
-
-Gitlawb Node is live early infrastructure. It is useful today, but some security and reliability features are intentionally staged for compatibility with existing nodes.
-
-Good today:
-
- Local or Docker node startup.
- Postgres-backed repo metadata.
- Bare git repository storage.
- Git smart-HTTP clone/fetch/push.
- RFC 9421-signed writes.
- DID identities.
- `gl` CLI workflows.
- libp2p peer discovery/gossip foundation.
- Optional Tigris/S3 storage.
- Optional IPFS/Pinata and Arweave/Irys hooks.
- Optional Base node-operator staking/heartbeat hooks.
-
-Known limitations:
-
- Private repository read enforcement is not wired yet. Treat public nodes as public infrastructure unless you restrict access at your proxy/firewall.
- UCAN chain validation and revocation are not complete.
- Repository write authorization is not capability-complete yet; HTTP signatures prove identity, not full authorization policy.
- Peer writes are signed by upgraded nodes, but strict signed-peer enforcement is opt-in during rolling upgrades.
- GraphQL mutations need mutation-aware auth before becoming a public write surface.

-## Quickstart: run a local node
-
-The fastest path is Docker Compose. It starts a node and Postgres.
+The fastest way to run a node is via Docker. You'll get a node + Postgres locally with one command.

 ```bash
-git clone https://github.com/Gitlawb/node.git
+git clone https://github.com/gitlawb/node.git
 cd node
 cp .env.example .env
 docker compose up -d
 ```

-Your local node will serve:
+Your node is now serving:

-| Service | Default |
-|---|---|
-| HTTP API + git smart-HTTP | `http://localhost:7545` |
-| libp2p QUIC/UDP | `7546` |
-| Postgres | compose-managed |
+- HTTP + git smart-HTTP on `:7545`
+- libp2p gossip on `:7546`

 Verify:

 ```bash
 curl http://localhost:7545/health
-curl http://localhost:7545/api/v1/stats
-```
-
-Expected health response:
-
-```json
-{ "status": "ok" }
-```
-
-Stop it:
-
-```bash
-docker compose down
 ```

 ---

-## Install the CLI
+## How it works

-```bash
-# npm (macOS / Linux)
-npm install -g @gitlawb/gl
+- **Identity** — every actor (human or agent) is an Ed25519 keypair → `did:key:z6Mk...`. No accounts, no passwords.
+- **Auth** — every write is signed via HTTP Signatures (RFC 9421).
+- **Delegation** — UCAN capability tokens.
+- **Storage** — local disk + optional S3-compatible bucket (Tigris, MinIO, AWS S3).
+- **Networking** — libp2p Gossipsub for ref-update events, Kademlia DHT for node discovery.

-# Homebrew (macOS / Linux)
-brew install gitlawb/tap/gl
-
-# curl (macOS / Linux)
-curl -fsSL https://gitlawb.com/install.sh | sh
-
-# PowerShell (Windows)
-irm https://gitlawb.com/install.ps1 | iex
-```
-
-Or build from source:
-
-```bash
-cargo build --release -p gl -p git-remote-gitlawb -p gitlawb-node
-```
-
-Put these binaries on your `PATH`:
-
-```txt
-target/release/gl
-target/release/git-remote-gitlawb
-target/release/gitlawb-node
-```
-
-Check your setup:
-
-```bash
-gl doctor
-```
-
---
-
-## First repo flow
-
-Create an identity:
-
-```bash
-gl identity new
-gl identity show
-```
-
-Register against your local node:
-
-```bash
-gl register --node http://localhost:7545
-```
-
-Create a repo:
-
-```bash
-gl repo create my-repo --description "My first Gitlawb repo" --node http://localhost:7545
-```
-
-Use the git remote helper:
-
-```bash
-export GITLAWB_NODE=http://localhost:7545
-git clone gitlawb://did:key:z6Mk.../my-repo
-```
-
-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.

-
-| Concept | Meaning |
-|---|---|
-| DID | A user, agent, or node identity derived from an Ed25519 public key. |
-| HTTP Signature | RFC 9421 signature proving control of the DID key for write requests. |
-| Ref certificate | Signed record of a ref update. Useful for audit and replication. |
-| UCAN | Delegation token for future capability-based workflows. |
-| Peer announce | Node-to-node HTTP announcement of DID + public URL. |
-| Gossipsub | libp2p topic for ref-update events. |
-| Smart HTTP | Standard git protocol over HTTP for clone/fetch/push. |

-## API surface
-
-The node exposes both git smart-HTTP routes and JSON APIs.
-
-Common public read routes:
-
-```txt
-GET /health
-GET /
-GET /api/v1/stats
-GET /api/v1/contracts
-GET /api/v1/repos
-GET /api/v1/repos/{owner}/{repo}
-GET /api/v1/repos/{owner}/{repo}/tree
-GET /api/v1/repos/{owner}/{repo}/blob/{path}
-GET /api/v1/repos/{owner}/{repo}/issues
-GET /api/v1/repos/{owner}/{repo}/pulls
-GET /api/v1/peers
-GET /{owner}/{repo}/info/refs
-POST /{owner}/{repo}/git-upload-pack
-```
-
-Signed write routes include:
-
-```txt
-POST /api/v1/repos
-POST /api/register
-POST /api/v1/repos/{owner}/{repo}/fork
-POST /api/v1/repos/{owner}/{repo}/issues
-POST /api/v1/repos/{owner}/{repo}/pulls
-POST /api/v1/repos/{owner}/{repo}/pulls/{number}/merge
-POST /api/v1/repos/{owner}/{repo}/hooks
-POST /api/v1/bounties/{id}/...
-POST /{owner}/{repo}/git-receive-pack
-```
-
-These peer write routes support staged rollout:
-
-```txt
-POST /api/v1/peers/announce
-POST /api/v1/sync/notify
-```
-
-When `GITLAWB_REQUIRE_SIGNED_PEER_WRITES=false`, unsigned legacy peers are accepted on those two routes, but signed requests are verified when signature headers are present. Once all live peers upgrade, operators can set:
-
-```bash
-GITLAWB_REQUIRE_SIGNED_PEER_WRITES=true
-```
-
-`POST /api/v1/sync/trigger` is not part of the staged rollout: it always requires a signature in both config modes and returns 401 without one, because each call drives an O(peers) outbound fan-out.
+The node is **stateless beyond Postgres + the repos directory.** You can scale horizontally by pointing multiple nodes at a shared S3 bucket and database.

+### On-chain Proof-of-Stake (advanced, optional)
+
+The node supports an optional on-chain PoS layer where operators register their DID, stake $GITLAWB on Base L2, and receive a share of protocol fees. Smart contracts are in a separate repository at [github.com/gitlawb/contracts](https://github.com/gitlawb/contracts).
+
+PoS is **disabled by default** and currently paused pending external audit. To enable, set `GITLAWB_CONTRACT_NODE_STAKING` and `GITLAWB_OPERATOR_PRIVATE_KEY`. See [`docs/RUN-A-NODE.md`](docs/RUN-A-NODE.md) for details.

-## Roadmap
+## Architecture

-The current maintainer focus is live-network stability first.
-
-Short-term priorities:
-
-1. Keep CI green: fmt, clippy, tests, release build.
-2. Add Docker and installer smoke tests.
-3. Improve operator docs and `gl doctor` checks.
-4. Harden peer writes and publish the signed-peer rollout plan.
-5. Implement repo write authorization: owner checks, protected branches, and UCAN capability checks.
-6. Implement private-read enforcement or remove private repo affordances until it exists.
-7. Add metrics for pushes, fetches, pack sizes, peer sync, failed auth, and webhooks.
-
-Product direction:
-
-1. Reliable repo replication.
-2. Health-aware peer syncing.
-3. CDN-style clone/fetch routing to healthy replicas.
-4. App asset/build delivery from nodes.
-5. Operator dashboard and desktop UX.

 ## Dependency Vulnerability Status

-| Area | Status |
-|------|--------|
-| Dependabot alerts | Current open Rust alerts were addressed by updating vulnerable dependencies, removing libp2p mDNS, and moving P2P transport from TCP/Yamux to QUIC/UDP. |
+| Crate | Advisory | Severity | Status |
+|-------|----------|----------|--------|
+| `rsa 0.9.x` | RUSTSEC-2023-0071 Marvin Attack | Medium | Unexploitable — bundled via `sqlx-mysql` internals; gitlawb uses PostgreSQL only, MySQL auth code is never executed. No upstream fix available. |
+| `lru 0.12.x` | RUSTSEC-2026-0002 unsound IterMut | Warning | In `libp2p-swarm`; the specific unsafe code path is internal to libp2p and not reachable through gitlawb's usage. No upstream fix yet. |

 ## Known Limitations (Planned for v0.2)

-These are **documented, accepted limitations** for the current live release and should be prioritized without breaking existing nodes during rolling upgrades.
+These are **documented, accepted limitations** for the current testnet release. They will be addressed before mainnet.

 ### UCAN chain validation
 - The auth middleware verifies HTTP Signatures and token structure, but does not yet walk the full UCAN delegation chain.
 - **Impact:** A node cannot yet enforce fine-grained capability delegation. Currently, any registered agent with a valid HTTP Signature can push.
- **Mitigation:** Keep write endpoints signed, treat public nodes as public infrastructure, and treat trust scores as soft rate-limiting signals rather than authorization.
+- **Mitigation:** Nodes can set `GITLAWB_PUBLIC_READ=false` to restrict access. The v0.1 trust score system provides soft rate limiting.
 - **Fix target:** v0.2

 ### UCAN revocation
 - Issued UCAN tokens cannot be revoked before expiry.
 - **Impact:** If a keypair is compromised, the attacker retains access until the UCAN expires (default: 30 days).
- **Mitigation:** Regenerate your identity (`gl identity new --force`) and re-register to issue a new UCAN. Until revocation/blocklisting is implemented, operators should remove compromised DIDs directly from their local database.
+- **Mitigation:** Regenerate your identity (`gl identity new --force`) and re-register to issue a new UCAN. Nodes will reject the old DID on sight if manually blocklisted.
 - **Fix target:** v0.2

 ### git-receive-pack authentication
- The `git-receive-pack` endpoint enforces HTTP Signature auth. Plain Git smart-HTTP clients do not generate those headers, so the `git-remote-gitlawb` helper is required for pushes.
- **Impact:** Direct HTTP pushes without RFC 9421 headers are rejected; users need `gitlawb://` remotes or equivalent signed clients.
- **Mitigation:** Use `gitlawb://` remote URLs and keep `git-remote-gitlawb` on the user's `PATH`.
+- The `git-receive-pack` endpoint enforces HTTP Signature auth via the `git-remote-gitlawb` remote helper. Direct HTTP push without the helper is currently unauthenticated on v0.1 nodes.
+- **Impact:** A node operator accepting direct HTTP git pushes (not via `gitlawb://`) cannot verify the pusher's identity.
+- **Mitigation:** Use `gitlawb://` remote URLs. Do not expose `POST /*/git-receive-pack` to untrusted networks.
 - **Fix target:** v0.2

-### Private repository reads
- Repository records have an `is_public` field and the node exposes `GITLAWB_PUBLIC_READ`, but per-repository private-read enforcement is not wired in the current live release.
- **Impact:** Do not store private repositories or secrets on public nodes.
- **Mitigation:** Run isolated nodes for non-public data and restrict network access at the reverse proxy or firewall layer.
- **Fix target:** v0.2
-
-### Peer route hardening rollout
- Peer announce and sync notification routes accept signed requests and verify DID matches when a signature is present.
- **Impact:** Unsigned peer writes are still accepted by default so existing live nodes can keep communicating during rolling upgrades.
- **Mitigation:** After all active peers run signed-node builds, operators can set `GITLAWB_REQUIRE_SIGNED_PEER_WRITES=true`.
- **Fix target:** staged rollout

-# 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

-# restores Cargo.lock; a manual regen may refresh it — `git checkout Cargo.lock`
-# afterward if you did not intend that.)

-//! Pluggable provenance attachments for gitlawb ref-update certs.
-//!
-//! A `gitlawb/ref-update/v1` cert proves who pushed and where a ref moved to.
-//! It does not say how the commit was produced. This crate adds an optional
-//! `attestations` field that lets any provenance system (SLSA, Sigstore,
-//! in-toto, agent runtimes) attach a typed, signed blob bound to the cert by
-//! its hash.
-//!
-//! The cert format stays additive. A cert with no attestations serializes the
-//! same bytes it does today, and existing decoders (which do not set
-//! `deny_unknown_fields`) silently drop the new `attestations` field rather
-//! than reject the cert.
-//!
-//! ## Wire shape
-//!
-//! ```json
-//! {
-//!   "type": "gitlawb/ref-update/v1",
-//!   // ...standard cert fields...,
-//!   "signatures": [...],
-//!   "attestations": [
-//!     {
-//!       "type": "covenant/exec/v1",
-//!       "payload": { /* opaque, type-specific */ },
-//!       "cert_hash": "<sha256 hex of JCS-encoded cert body>",
-//!       "signer":    "did:key:z6Mk...",
-//!       "sig":       "<base64url ed25519 over the signing input>"
-//!     }
-//!   ]
-//! }
-//! ```
-//!
-//! ## Canonical bytes
-//!
-//! Hashing and signing inputs use JCS (RFC 8785) so they reproduce across
-//! implementations regardless of struct field order or JSON library.
-//!
-//! The cert hash is `SHA-256(JCS(cert_body_without_signatures_or_attestations))`,
-//! expressed as lowercase hex on the wire. Uppercase is non-canonical and
-//! rejected on verify so the JCS signing input is uniquely determined by the
-//! cert bytes alone — there is no implicit normalization rule that
-//! cross-language signers might miss.
-//!
-//! The attestation signing input is the byte string
-//! `b"gitlawb-attest-sig/v1\n" || JCS({type, payload, cert_hash})`. The
-//! domain tag is in the byte stream, not the canonical JSON, so an attestation
-//! cannot be confused with a same-shape JCS document signed for a different
-//! protocol that uses the same Ed25519 key.
-//!
-//! ## DID:key
-//!
-//! Signers are `did:key` DIDs over Ed25519, encoded with the multibase
-//! base58btc (`z`) prefix per the W3C DID:key specification. Non-base58btc
-//! encodings of the same public key are rejected on verify so allowlists,
-//! deduplication, and signer-pinning policies that compare `signer` strings
-//! stay consistent across peers.
-//!
-//! ## Verification
-//!
-//! [`Registry`] looks up a verifier by type discriminator. [`Policy`] decides
-//! what to do when no verifier matches: `AcceptKnown` (default) lets unknown
-//! types pass without trust; `RequireAll` enforces a per-repo allowlist while
-//! still letting unrelated attached attestations through unverified (so a
-//! third-party attachment cannot DoS the cert); `RejectUnknown` rejects
-//! anything unregistered.

-//! Repo replica registration API.
-//!
-//! Lets a node tell the origin "I'm hosting a replica of your repo." The
-//! origin records the (replica DID, replica URL) pair and exposes the list
-//! publicly so anyone can see how many nodes are mirroring a given repo.
-//!
-//! Endpoints:
-//! - `PUT  /api/v1/repos/:owner/:repo/replicas`     (auth)   register
-//! - `DELETE /api/v1/repos/:owner/:repo/replicas`   (auth)   unregister
-//! - `GET  /api/v1/repos/:owner/:repo/replicas`     (public) list
-//!
-//! Auth model: the caller's DID (verified via HTTP Signatures) is the
-//! replica's identity. There's no separate "claim this URL" check — replicas
-//! self-report their public URL. Operators viewing the list should treat
-//! replica URLs as advisory until they actually reach out and verify.

-//! 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.

-//!   * is fetch traffic flowing? — `gitlawb_fetches_total`
-//!   * are signature checks passing or failing? —

-//!   * how big are the packs we're sending and receiving? —
-//!     `gitlawb_pack_size_bytes`
-//!   * a single `gitlawb_info{version, did}` gauge = 1, for joins/dashboards
-//!   * currently-connected peer count — `gitlawb_peers_connected`
