feat(infra): Fly config for node3 on the public OSS build

Deploys node3.gitlawb.com (Fly app gitlawb-node-3, nrt) from this repo's
Dockerfile instead of its old private source. Canary for migrating the
bootstrap nodes; node + node2 follow.

- region nrt, reuses volume gitlawb_data (identity + repos) and the
  attached Postgres (DATABASE_URL secret)
- corrects PUBLIC_URL to https://node3.gitlawb.com, bootstrap peers to
  node + node2 (not self), drops vestigial GITLAWB_DB (v0.3.9 is
  Postgres-only)
- 1024MB (was 256MB — too small for v0.3.9)

Migration note: the existing volume was created by the old root-based
image, so /data was root-owned; the public image runs as uid 1000 and
needed a one-time 'chown -R 1000:1000 /data'. node + node2 will need the
same until the image entrypoint self-heals ownership.

-## Summary
-
-<!-- One or two sentences: what changes and why it matters. -->
-
-
-
-## Motivation & context
-
-<!-- What problem does this solve? Link prior discussion if any. -->
-Closes #
-
-## Kind of change
-
-- [ ] Bug fix
-- [ ] Feature
-- [ ] Security fix
-- [ ] Docs
-- [ ] Tests / CI
-- [ ] Refactor (no behavior change)
-- [ ] Breaking or protocol change (issue required first)
-
-## What changed
-
-<!-- Bullet the concrete changes. Note the crate(s) touched:
-     gitlawb-core / gitlawb-node / gl / git-remote-gitlawb -->
-

-
-## How a reviewer can verify
-
-<!-- Commands to run, or repro steps for a bug plus proof it's fixed. -->
-
-```sh
-
-```
-
-## 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

-# Contributor guide for coding agents
-
-This file carries the rules a patch author cannot recover from the code alone, for humans and coding agents alike. For build, test, and PR basics, read `CONTRIBUTING.md` first.
-
-## Authorization invariants (the rules PRs most often break)
-
-Every repo-scoped endpoint must bind the caller to an authorization decision before serving or mutating anything. The `known_ungated` allowlist in `authz_guard::every_repo_scoped_handler_is_gated` is empty on main: `list_webhooks`, `list_replicas`, and `list_protected_branches` are gated (`list_webhooks` with read-visibility then owner; the other two with `authorize_repo_read`). Do not re-open those surfaces as exceptions.
-
-- Owner-only mutations (visibility, webhooks, protected branches, merges) are gated against the repo owner. Three gate forms are in use and all are recognized: webhooks and merges call `require_repo_owner` (`crates/gitlawb-node/src/api/mod.rs`), visibility uses its module-local `require_owner`, and protected branches compare inline with `did_matches`. Use the form the surrounding module already uses.
-- Not every write is owner-only, and that is by design: `star_repo`/`unstar_repo` bind to the signer (they still require repo read access), `register_replica`/`unregister_replica` bind to the replica's own DID, the bounty actions (claim, submit, approve, cancel, dispute) have their own multi-party rules, and closing a PR or issue is owner-or-author. Do not add owner gates to these.
-- Content-serving reads (blobs, trees, raw files) gate through `authorize_repo_read` with the specific path being served, so a withheld subtree is denied even on an otherwise-public repo; repo-level reads (listings) pass `"/"` by the helper's own contract. The source scans below cannot check this argument's value, so review will.
-- A route that reaches repo data through a global id, with no repo in its path, or through an extractor shape the scans do not recognize still needs the same gate; the scans cannot see those.
-- Read-surface denials must not reveal existence: a caller who may not read a repo (or a withheld subtree) gets the same 404 as a missing repo, never a 403. (Owner-gated mutations currently return 403 after the repo lookup; do not widen that shape to read paths.)
-- Two tests in module `authz_guard` (`crates/gitlawb-node/src/api/mod.rs`) scan handler sources and fail on a repo-scoped handler without a recognized gate: `every_in_scope_mutation_has_its_gate` and `every_repo_scoped_handler_is_gated`. If they fail on your handler, add the gate. The second test's `known_ungated` allowlist is empty; never add an entry to it without an open issue and review.
-
-## Adding or changing routes
-
-- A new gated handler needs tests proving its route-specific gate fires: exercise an unauthorized authenticated caller and an anonymous caller where applicable, assert the exact denial status each way, and assert the body leaks nothing. The non-owner tests in `crates/gitlawb-node/src/test_support.rs` show the shape for owner-gated routes.
-- A new mutation handler also gets a row in `every_in_scope_mutation_has_its_gate` naming its gate type; the per-handler row is the point of that test.
-- A table-driven deny suite covering every deny-bearing route is in review (#194, #195). If it is present in your checkout, add a probe row there for any new deny-bearing route.
-
-## Verifying signatures and certificates
-
-- Derive the verifying key from something outside the artifact you are checking: the node's own DID, a pinned or configured value, a peers lookup. A key read from a field of the object being verified (`Did::from_str(&cert.node_did)`) only proves the artifact is self-consistent, and identities here are permissionless, so anyone can mint a keypair, name it in the artifact, self-sign, and be told it is valid. A mismatch against that anchor has to fail the result, not log a warning.
-- A handler whose correct answer is "valid" needs a positive case driven by a trusted, independently anchored artifact, and a rejection case for a well-formed, fully populated forged artifact. Invalid-only suites miss an implementation that rejects everything; a forged artifact that still returns valid is the regression that matters.
-- The fields a signature covers are a versioned format. Adding one invalidates every artifact already signed, so give the payload a version, keep a path that verifies the older form, and add a test that verifies an artifact signed before your change.
-
-## Removing a serving path
-
-When a fix removes a path that used to serve content, the same PR must add a test asserting the removed path now denies. The deletion is what turns that test green; without it the path can quietly come back.
-
-## Database migrations
-
-Schema changes are code-defined in `MIGRATIONS` (`crates/gitlawb-node/src/db/mod.rs`). Always append a new versioned entry; never edit an entry that has merged (operators deploy from main). Test runs build the schema from scratch, so editing an applied version stays green in CI while breaking every existing deployment.
-
-## Client behavior (`gl`, `git-remote-gitlawb`)
-
-When a node denies a request, surface the denial to the user. Never render a denial as an empty list or a silent success; that turns an authorization boundary into invisible data loss.
-
-## Toolchain and CI reality
-
-- MSRV is Rust 1.91 (`rust-version` in the workspace `Cargo.toml`). The MSRV CI job runs `cargo check --workspace --all-targets` on exactly 1.91, so check that an API you rely on is stable there; the full test suite runs on stable.
-- The PR workflow runs these jobs on every PR: `cargo fmt --check`, `cargo clippy --workspace --all-targets -- -D warnings`, `cargo test --workspace` (against Postgres), a release build, `cargo audit`, the MSRV check, and a Docker build. The `main` branch ruleset currently requires one approving review but does not require these checks to pass before merge; a failing job should block review approval in practice, but nothing enforces that mechanically today.
-- Conventional commit titles (`feat:`, `fix:`, `docs:`, ...) are required by convention and drive releases, but no CI job checks them; a bad title fails review, not the pipeline.

 3. **No breaking changes without discussion.** Open an issue first for protocol-level changes.
 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.

-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

-- **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.

-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.

 Known limitations:
 
-- Repository write authorization is not secure by default: `GITLAWB_ENFORCE_OWNER_PUSH` defaults to `false` for compatibility, so a valid HTTP Signature identifies a pusher but does not enforce owner-only pushes.
-- UCAN proof chains are validated when supplied, but UCAN capabilities are not consulted by write authorization and the root issuer is not independently trust-anchored. UCANs therefore do not yet grant scoped collaborator access.
-- Agent lifecycle revocation is not enforced by HTTP Signature authorization; do not rely on removing or revoking an agent record to block a compromised signer.
-- Read visibility is not a blanket data-classification boundary: task, IPFS-pin, and Arweave-anchor listings are not repository-gated; withheld path names can be visible to a root reader; and later visibility changes cannot retract content already announced or externally anchored.
+- Private repository read enforcement is not wired yet. Treat public nodes as public infrastructure unless you restrict access at your proxy/firewall.

-### Full lifecycle against an iCaptcha-enforcing node
-
-Public nodes (e.g. `node.twigpine.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

-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.

-### Fetching an object by CID
-
-```bash
-gl ipfs list                                  # CIDs this node has pinned
-gl ipfs get bafkrei... > object.bin           # object bytes on stdout
-```
-
-Objects that were pinned before the node started recording which repo they came
-from are found by scanning its repo inventory, and that scan stops at the
-per-request ceilings in the [Configuration](#configuration) table. A stopped scan
-answers 503 with a resume token instead of a false "not found", and `gl ipfs get`
-follows the token automatically: up to 8 resumes after the first request, so at
-most 9 calls to the node, waiting between attempts for as long as the node's
-`Retry-After` asks and never longer than 5 seconds.
-
-The whole ladder runs under a 60 second wall-clock deadline. The deadline bounds
-the search, not the download: each attempt gets the time left on it to produce
-response headers, and once an object is found its bytes stream outside that
-deadline. They are not unbounded, though. The client's own 30 second HTTP timeout
-is a total request timeout, running from the start of a request until its body
-has finished, so a transfer still going 30 seconds after its request began is cut
-off. Waits between attempts never run past the deadline either, so a single run
-spends at most around 90 seconds on the network: the deadline plus the 30 second
-timeout covering the last attempt. Writing the object out sits outside both
-bounds, so piping into a reader that stops reading can hold the command open
-longer than that.
-
-Two node-side brakes end a ladder early and are reported rather than retried
-around. A 429 is terminal, because the node's rate-limit window is an hour and
-that wait cannot be honored inside one invocation; a transient overload (a 503
-carrying no incomplete-scan code) is retried on the token already held, under the
-same cap, clamp and deadline. The per-IP fanout brake can also stop a ladder well
-short of the 9 calls, so automatic resumption is not a guarantee of reaching the
-object.
-
-When a bound stops the ladder with a usable token in hand, the command prints the
-token and the invocation that continues from it before exiting nonzero:
-
-```txt
-resume from where this stopped: gl ipfs get bafkrei... --scan <token>
-```
-
-Run that to carry on from where the scan stopped. Re-running without `--scan`
-restarts at the first row, reproduces the same truncation and spends the node's
-per-IP budget again, so the token is the only thing that makes progress. Tokens
-are valid for an hour.

-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. Staged rollout relaxes who may announce, not who owns a peer row. An unsigned announce may register a previously unseen peer, and it may refresh an existing row whose `http_url` is unchanged, but changing an existing peer's `http_url` requires an RFC 9421 signature from that peer's own DID and is refused with 403 otherwise. An unsigned announce can only register a `did:key`, since that is the only method whose verifying key can be resolved and therefore the only kind of row anyone could ever correct through the signed path; any other DID is refused with 400.

 ```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 flag is not HTTP-only. It also gates inbound gossip ref-update events on the libp2p mesh, which carry an Ed25519 payload signature rather than RFC 9421 headers because there are no HTTP headers to sign. Set to `true`, an unsigned gossip event is dropped. Set to `false`, an unsigned event is accepted with a warning during the rolling-upgrade window, and the write budget it consumes is charged to the forwarding peer rather than to the DID it claims, since an unsigned event's claimed DID is asserted and not proven. A present-but-invalid signature is refused in both modes; that is forgery, not an un-upgraded peer.
-
-Because the flag now spans both transports, the rollout order matters in one direction: **upgrade every gossip-publishing peer to a build that signs events before you set this to `true`.** Enabling it while an old publisher is still live drops that publisher's ref-updates on arrival, and the publisher sees no error, because gossip has no response to carry one. Upgrading the HTTP peers alone is not sufficient.
-
-There is a second precondition on gossip ingest that the flag does not control. A publisher's `node_did` must already exist in the receiving node's peers table, or the event is dropped as an unknown peer DID. This holds in both modes, signed and unsigned alike: a valid signature proves key possession, not membership. Rows reach that table over HTTP, either from `GITLAWB_BOOTSTRAP_PEERS` when this node contacts a bootstrap peer and records the DID it reports, or from a prior `POST /api/v1/peers/announce`. So a peer that only ever joined the libp2p mesh, with no HTTP announce and no bootstrap contact in either direction, will have its ref-updates dropped even with a good signature and the flag off. If gossip is silently not landing from a peer you can see on the mesh, check that its DID is in `GET /api/v1/peers` on the receiving side first.

 ## Configuration
@@ -397,63 +291,21 @@ Important node settings:
 | `GITLAWB_P2P_PORT` | libp2p QUIC/UDP port. Use `0` to disable. |
 | `GITLAWB_BOOTSTRAP_PEERS` | Comma-separated HTTP peer URLs. |
 | `GITLAWB_P2P_BOOTSTRAP` | Comma-separated libp2p multiaddrs. |
-| `GITLAWB_P2P_KEY` | Path to the node's persistent libp2p identity key file, which fixes the PeerId across restarts. Must name a key file inside a directory, such as `/data/keys/p2p.key` or `./keys/p2p.key`. Two kinds of problem are handled differently. A value that cannot name a securable key file at all (a bare filename, `..` traversal, a trailing `/`, the filesystem root, or a `~/` path that escapes home) is refused before the node binds, so the process exits. Anything wrong with the storage itself (a symlinked or non-directory parent, an unsafe ancestor or working directory, an unreadable or malformed key) leaves p2p off while HTTP keeps serving; the node logs it at error level as `p2p_identity_key_load_failed` and sets the `gitlawb_p2p_identity_key_load_failed` metric to 1. Note that `/health` still reports healthy in that state, so alert on the log event or the metric rather than on the health check. Correcting the storage and restarting restores the same PeerId. On Unix a new key is created `0600` inside a `0700` directory. A key directory that grants access beyond its owner is tightened to `0700` on start; one that is closed too far is refused with a `chmod 700` remedy rather than widened, since a directory locked down on purpose is an operator decision. Rotate the key only when the node logs that the directory was group- or world-writable (or the key file itself was group- or world-readable). An ordinary `0755` directory is tightened too, but others could not read a `0600` key or replace its directory entry. An existing key file is never modified: one with group or other bits set is rejected (`chmod 600`), and so is one this node cannot read. On other platforms no permissions are enforced. Default `~/.gitlawb/p2p.key`; point it at a persistent volume when running in a container. |
 | `GITLAWB_BOOTSTRAP_DISABLE_SEEDS` | Disable embedded seed peers for isolated dev/test networks. |
-| `GITLAWB_REQUIRE_SIGNED_PEER_WRITES` | Require peer writes to prove their DID on every transport: RFC 9421 signatures on the announce/sync routes, and an Ed25519 payload signature on gossip ref-update events. Defaults to `false` during the staged rollout below. Upgrade every gossip publisher before enabling, or their updates are dropped with no error on their side. |
-| `GITLAWB_ENFORCE_OWNER_PUSH` | Require the authenticated pusher to be the repo owner on `git-receive-pack`. **Defaults to `true`.** A `did:key` signature is authentication, not authorization — anyone can mint a key and sign — so with this off every signed caller may push to every repository, private ones included. Delegated and CI keys count as non-owners: a UCAN `git/push` capability is verified but not yet honored for authorization, so they cannot push while this is on. Set `false` only for a rolling upgrade; see [`docs/RUN-A-NODE.md`](docs/RUN-A-NODE.md). |
+| `GITLAWB_REQUIRE_SIGNED_PEER_WRITES` | Require signed peer announce/sync writes. |
 | `GITLAWB_AUTO_SYNC` | Enable automatic sync from known peers. |
 | `GITLAWB_MAX_PACK_BYTES` | Max git pack body size for smart-HTTP routes. |
-| `GITLAWB_GIT_SERVICE_TIMEOUT_SECS` | Max seconds a served git upload-pack, receive-pack, or `info/refs` advertisement may run before it is aborted (504). Default 600. Also bounds the withheld-blob classification walk (on both the upload-pack serve and receive-pack replication paths) and the push-side pin-candidate discovery (`rev-list` / `cat-file`), each reaped via process-group teardown at the deadline. On the path-scoped upload-pack path the classification walk and the pack serve share ONE deadline, so this value bounds their combined duration rather than granting each stage a full budget: a walk that consumes it leaves the serve nothing and the clone gets a 504. Serving large path-scoped repos may therefore need a higher value than they did when each stage was budgeted separately. Accepted range is 1 to 3153600000 (100 years), since the node derives deadlines from this value and a larger one cannot be represented. |
-| `GITLAWB_GIT_ACQUIRE_TIMEOUT_SECS` | Max seconds the storage-acquisition phase (Tigris HEAD/GET, push advisory-lock) of a served git op may run before the request is shed with a 503, separate from the git-run timeout. The concurrency permit is released on expiry so a stalled backend cannot pin the pool. Default 30. |
-| `GITLAWB_MAX_CONCURRENT_GIT_OPS` | Max concurrent served git READ ops (upload-pack and its `info/refs` advertisement) across all callers; over-cap sheds a 503 + Retry-After. Anonymous reads draw from this pool, so pair it with `GITLAWB_MAX_CONCURRENT_READS_PER_CALLER`. Pushes and the receive-pack advertisement have their own pools, so a read flood cannot shed an authenticated push. Default 128. |
-| `GITLAWB_MAX_CONCURRENT_GIT_PUSHES` | Max concurrent `git-receive-pack` POST operations, in a pool separate from the read pool. The anon receive-pack `info/refs` advertisement runs in a third pool of the same size, disjoint from both, so an advertisement flood cannot shed a push either. Two per-source push caps are derived from this value (`/8`, floor 1) and have no env var of their own. Over-cap sheds a 503 + Retry-After. Default 32. |
-| `GITLAWB_MAX_CONCURRENT_READS_PER_CALLER` | Max concurrent read ops a single caller may hold, so one caller cannot monopolize the read pool. Keyed on the resolved source IP, never the DID, and only as granular as `GITLAWB_TRUSTED_PROXY`: left unset, a node behind an edge or NAT keys every caller on the edge IP and this collapses to one global cap. Default 16. |
-| `GITLAWB_MAX_CONCURRENT_PIN_TASKS` | Max post-push pin loops (IPFS + Pinata) running concurrently across all repos. This caps how many loops RUN at once, not how much object-id list memory the node retains: on the local IPFS path a loop parked waiting for a permit still holds its full list. Do not size memory from this knob alone. A loop over cap waits, never drops a pin. Default 8. |
-| `GITLAWB_REPO_LEASE_MAX_WAITERS` | Max pushes parked at once waiting for the same repo's write lease. Each waiter pins its buffered pack body, so this bounds that memory for a hot repo; past the cap the newest push sheds a 503 + Retry-After instead of queueing. Pushes to other repos are unaffected, and the lease holder is not counted. Default 8. |
-| `GITLAWB_MAX_CONCURRENT_IPFS_WALKS` | Max concurrent `GET /ipfs/{cid}` visibility walks across all callers (own pool, disjoint from the served-git pools); over-cap sheds 503. Default 32. |
-| `GITLAWB_IPFS_WALK_PER_SOURCE` | Max concurrent `/ipfs` walks a single source IP may hold. Default 4. |
-| `GITLAWB_IPFS_MAX_LEGACY_PROBES` | Max legacy (NULL-provenance) repos probed per `/ipfs/{cid}` request, bounding the scan-fallback fan-out. A truncated scan returns a retryable 503, not a false 404. Default 256. |
-| `GITLAWB_IPFS_MAX_LEGACY_SCAN_ROWS` | Max repo rows one `/ipfs/{cid}` request's legacy scan may read from the database. The probe ceiling above only starts counting once a probe runs, and quarantined or private repos are denied before that, so this is what bounds a scan over an inventory that denies the caller everywhere. A truncated scan sheds a retryable 503 carrying an opaque `continuation` token; echoing it as `?scan=` resumes the scan where it stopped. Every per-request ceiling on this path (rows, probes, visits, retained rule bytes) mints one, so each request advances the ladder by at least the rows it read and a holder buried past a ceiling is reached in a bounded number of requests, `ceil(repos / ceiling) + 1` when this row ceiling is the one that binds. No ceiling ever produces a 404. Every page is charged to the caller's `/ipfs` work allowance, so raising this raises that allowance too. Lowering it sharpens an oracle: because a truncation emits a token and a completed wrap does not, laddering to the end reveals the node's total repo count (private and quarantined included) to within one ceiling. Default 2048. |
-| `GITLAWB_IPFS_MAX_REPOS_WALKED` | Max expensive path-scope visibility walks a `/ipfs/{cid}` request may run per phase; over-cap repos are skipped and the scan continues, shedding a retryable 503 (not a false 404) if the object is then found nowhere. The effective cap is the tighter of this knob and the node's internal history-walk ceiling of 17 (`MAX_PIN_SOURCES + 1`), so a value above 17 has no effect while a value below it does tighten the cap. It is charged per phase: the provenance lookup and the legacy-scan fallback get separate equal budgets, so one request can run up to twice the cap in total. Default 64. |
-| `GITLAWB_IPFS_MAX_REPO_VISITS` | Ceiling on repos one `/ipfs/{cid}` request may visit (acquire + probe) past the visibility gate. Also the worst-case per-request Tigris fetch count. On exhaustion the scan stops with a retryable 503. Default 1024. |
-| `GITLAWB_IPFS_REQUEST_BUDGET_SECS` | Absolute wall-clock budget for one admitted `/ipfs/{cid}` request's acquire+walk lifetime. Per-stage clamps bound the acquire and walk stages to the remaining budget, and no stage starts once it is exhausted; the scan then stops with a retryable 503. The object-type probe and content-read `cat-file` subprocesses are budget-checked before starting and each also run under their own deadline (the lesser of `GITLAWB_GIT_SERVICE_TIMEOUT_SECS` and the remaining budget), reaped via process-group teardown, so a hung `cat-file` cannot hold the request's walk slot past it. One hang path is still unbounded: the probe's object-store readability check is a plain filesystem sweep with nothing to reap, so a wedged filesystem can hold the slot past the deadline. Default 600. Accepted range is 1 to 3153600000 (100 years), since the node derives a deadline from this value and a larger one cannot be represented. |
-| `GITLAWB_IPFS_RESOLVE_BUDGET_SECS` | Shorter budget for the pre-walk CID resolve inside an admitted `/ipfs/{cid}` request: the lookup that maps the requested CID to its git oid(s), which runs while the scarce walk admission is already held. A well-formed CID with no pin row does no probe and no walk work, so without this it could hold a walk slot for the whole request budget while nothing walked, and enough such requests shed every real retrieval at admission. The effective deadline is the lesser of this and the remaining request budget, so a value above `GITLAWB_IPFS_REQUEST_BUDGET_SECS` degrades to the request budget. Only the resolve is on this clock; walk and probe work stay on the request budget, so a slow but progressing scan is never shed by it. Default 10. Accepted range is 1 to 3153600000 (100 years). |
-| `GITLAWB_IPFS_RATE_LIMIT` | Max `/ipfs/{cid}` requests per client IP per hour (route flood brake). 0 disables. Default 600. |
 | `GITLAWB_TIGRIS_BUCKET` | Optional S3/Tigris shared repo storage bucket. |
 | `GITLAWB_PINATA_JWT` | Optional Pinata/IPFS warm-storage pinning. |
 | `GITLAWB_IRYS_URL` | Optional Irys/Arweave permanent anchoring. |
 
 Production note: change the default Postgres password before exposing a node publicly.
 
-Legacy-pin window: releases before the CID-resolver work stored the provider CID (Kubo dag-pb / Pinata) as a pinned object's resolver key. The `/ipfs/{cid}` resolver now recomputes the raw-content CID from the object bytes and refuses to serve a key that does not match, so `GET /api/v1/ipfs/pins` can still advertise an unrepaired legacy CID that 404s. Such a row is repaired opportunistically the next time a push carries the object again (its key is rewritten to the raw CID, the old value kept in `legacy_provider_cid`), but git negotiation omits objects the node already has, so most legacy rows never re-enter a push delta. A deferred one-shot startup sweep, not this opportunistic path, is what fully retires the advertise-then-404 window. Rows whose object bytes are gone stay withheld.
-
-### Upgrading: the PeerId rotates once
-
-This node's libp2p identity is now a keypair generated on first start and kept
-at `GITLAWB_P2P_KEY`, rather than one derived from the node DID. Every node
-therefore gets a new PeerId once, on the first start after upgrading, and keeps
-it from then on as long as that key file survives (put it on a persistent volume
-in a container).
-
-Two things to check before upgrading:
-
-- Any `GITLAWB_P2P_BOOTSTRAP` multiaddr that pins a peer's old PeerId with a
-  `/p2p/<PeerId>` suffix stops matching once that peer upgrades. Update the
-  suffix, or drop it and let identify supply the current one. Addresses without
-  the suffix keep working untouched.
-- `GITLAWB_P2P_KEY` must name a key file inside a directory, such as
-  `/data/keys/p2p.key` or `./keys/p2p.key`. A bare filename is refused at
-  startup, since the node will not keep its identity key in the working
-  directory.
-
-Peers found over `GITLAWB_BOOTSTRAP_PEERS` and the embedded seed list are
-unaffected, since those are HTTP URLs and carry no PeerId.

-These are documented limitations of the current live release. They should be prioritized without breaking existing nodes during rolling upgrades.
+These are **documented, accepted limitations** for the current live release and should be prioritized without breaking existing nodes during rolling upgrades.
 
-### Repository write authorization defaults
-- `git-receive-pack` verifies HTTP Signatures, but `GITLAWB_ENFORCE_OWNER_PUSH` defaults to `false` for compatibility during rollout.
-- **Impact:** With the default setting, a valid signature authenticates the pusher but does not require that DID to be the repository owner.
-- **Mitigation:** Set `GITLAWB_ENFORCE_OWNER_PUSH=true` on nodes where owner-only pushes are required. Confirm that every legitimate pusher uses the owner DID before enabling it.
+### 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.
+- **Fix target:** v0.2
 
-### UCAN delegation and revocation
-- The middleware validates a supplied UCAN's complete proof chain, but a root token is accepted without an independently trusted issuer anchor. `Ucan::can` is not yet used by write handlers, so a UCAN does not grant scoped repository access.
-- Agent lifecycle revocation is not checked by HTTP Signature authorization. Removing or revoking an agent record does not itself block a compromised DID from authenticating.
-- **Impact:** Do not use UCANs for collaborator permissions or rely on agent-record revocation as a key-compromise response.
-- **Mitigation:** Keep sensitive deployments behind operational network controls and enable owner-only push enforcement where it fits the deployment until trusted delegation and authorization-aware revocation are implemented.
+### 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.
+- **Fix target:** v0.2

 ### Private repository reads
-- Repository and path-scoped visibility checks are enforced for repository API and Git content reads. A denied whole-repository or root read returns the same 404 shape as a missing repository, so the denial does not reveal private-repository existence.
-- Sparse-clone support exposes withheld path globs to callers who may read the repository root. Do not put sensitive information in withheld path names.
-- `GET /api/v1/tasks`, `/api/v1/ipfs/pins`, and `/api/v1/arweave/anchors` are not repository-gated. Task records include a UCAN token; pin and anchor listings expose object and ref metadata.
-- Changing a repository's visibility controls future serving, but cannot retract ref metadata or configured external pins and anchors already announced while the repository was public. Do not push secrets to an announceable repository.
-- **Impact:** Visibility policies protect the repository and Git content routes they gate, not every metadata endpoint or previously published content.
-- **Remaining boundary:** This read control does not address the independent write-authorization and UCAN-delegation limitations described above.
-
-### Pull-request review enforcement
-- Pull-request review comments are not yet threaded or line-anchored, and merges do not enforce required approvals.
-- **Impact:** Teams must use their own review policy or external controls for merge approval requirements.
-
-### GraphQL mutation coverage
-- Existing GraphQL mutations require an authenticated signer, but a mutation-specific source-level guardrail has not yet been added for future mutations.
-- **Impact:** A new mutation could accidentally omit its signer check without an explicit test fence.
+- 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.

-# 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.

-//! Redirect policy shared by every Twigpine HTTP client that signs its requests.
-//!
-//! Both `gl` (async) and `git-remote-gitlawb` (blocking) attach RFC 9421
-//! `Signature` and `Signature-Input` headers, and reqwest strips only
-//! `Authorization`, `Cookie`, `Proxy-Authorization` and `WWW-Authenticate` when a
-//! redirect crosses hosts. A signature would survive that hop, and it binds

-//! answering 302 could hand a working credential to a host of its choosing and read
-//! as the caller anywhere until the clock-skew window closes. On a 307/308 the
-//! request body goes along with it, which for the remote helper is the pack.
-//!
-//! That same missing authority component is why the predicate also pins the
-//! request-target: `@path` is signed as the client sent it and verified as the node
-//! received it, so a same-origin hop that rewrites the path or the query (a
-//! trailing-slash or query normalization) makes the signature cover a target the
-//! node never saw and the read 401s. Only a hop that re-issues the identical target,
-//! an http-to-https upgrade being the one that matters in practice, is followed.
-//!
-//! The decision lives here rather than in either client because the two used to
-//! disagree: `gl` was scoped to the origin while the remote helper, the binary that
-//! actually runs `git clone gitlawb://`, still ran reqwest's default and followed
-//! anywhere. One predicate is what keeps a future third client from repeating that.
-//!
-//! The type is `url::Url`, which is what `reqwest::Url` re-exports, so both clients
-//! pass their attempt URLs straight in.
-
-/// Longest redirect chain followed. `reqwest::redirect::Policy::custom` replaces
-/// reqwest's built-in limit, so the bound has to be restated by every client that
-/// installs a custom policy; the value is reqwest's own default.
-///
-/// This counts FOLLOWS, matching `Policy::limited`: reqwest pushes the redirecting
-/// URL onto `previous` before consulting the policy, and `Limit(max)` refuses once
-/// `previous.len() > max`, so a caller comparing against this constant must use `>`
-/// too or it permits one hop fewer than it says.
-pub const MAX_REDIRECTS: usize = 10;

-/// Follow a redirect only when it stays on the origin that issued it AND re-issues
-/// the identical request-target.
-///
-/// `Policy::none()` would have been the simpler answer, but one same-origin redirect
-/// shape is legitimate here: a node fronted by a proxy that upgrades http to https,
-/// or otherwise re-issues the same path and query, so the policy is scoped rather
-/// than switched off.
-///
-/// Path and query must match exactly, and that is the request-target clause rather
-/// than an origin one. `@path` is signed as the client sent it and verified as the
-/// node received it, so a hop that rewrites either half leaves a signature covering
-/// a target nobody asked for and the node answers 401. Refusing the hop turns a
-/// confusing 401 into the 3xx that names what actually happened. One policy covers
-/// signed and unsigned callers alike, for the same reason the predicate is shared:
-/// two rules would drift.
-///
-/// The clause pins `@path`, and only `@path`. A Twigpine signature also covers
-/// `@method` and `content-digest`, and both of those are still open on a followed
-/// hop: on a 301, 302 or 303, reqwest 0.12.28 delegates to tower-http's
-/// `FollowRedirect`, which rewrites a POST to a GET and empties the body
-/// (tower-http-0.6.8 `src/follow_redirect/mod.rs:273-285`), while its
-/// `drop_payload_headers` removes only `Content-Type`, `Content-Length`,
-/// `Content-Encoding` and `Transfer-Encoding`. So `Signature`, `Signature-Input` and
-/// `Content-Digest` ride along on a request that no longer has the method or the body
-/// they were computed over. Only 307 and 308 preserve both. This predicate returning
-/// true therefore makes a GET-shaped hop safe to replay against the node's verifier
-/// and says nothing about a bodied one: a signed write must not rely on it alone.
-///
-/// `Url::query` is `None` for `/a` and `Some("")` for `/a?`, and those are two
-/// different request-targets on the node side too, so the comparison is strict and
-/// needs no special case.
-///
-/// Host and port must match exactly. Port is compared as `Url::port`, which is
-/// `None` for a scheme's default port, so http -> https on the same host compares
-/// equal while http -> http on a different port does not. A downgrade from https to
-/// http is refused as well: the target is the same host, but the signature would go
-/// out in cleartext, which is the same credential leak by a slower route.
-///
-/// Host comparison rides on `url`'s parse-time normalization (lowercasing and IDN
-/// -> punycode), so the spellings an attacker reaches for do not open a gap. That

-//! Sealed continuation token for the node's bounded legacy CID scan (INV-13).
-//!
-//! The `/ipfs/{cid}` resolver's legacy scan stops at a row ceiling and sheds a
-//! retryable 503. To let a holder buried past that ceiling still be reached, the
-//! shed carries the scan position so the caller can echo it back and resume. The
-//! whole point of the design is that the node keeps NO server-side scan state: the
-//! position rides in the caller's token.
-//!
-//! That makes the token an EMITTED continuation derived from a FETCHED row, and on
-//! a scan that served nothing every fetched row is by construction a private or
-//! quarantined repo the caller may not read. The row's `created_at` leaks its
-//! creation time and its `id` carries the owner's DID, so both halves are withheld
-//! fields and the token must be CONFIDENTIAL, not merely tamper-evident:
-//!
-//!   * AEAD-sealed (XChaCha20-Poly1305), never base64-of-plaintext and never
-//!     signed plaintext. Integrity is not confidentiality.
-//!   * A fresh `OsRng` nonce on EVERY seal. Under a stream cipher a repeated nonce
-//!     means repeated keystream, and an attacker who can force the node to seal a
-//!     position whose plaintext they know XORs two tokens and recovers a withheld
-//!     row's fields in full, strictly worse than emitting plaintext.
-//!   * FIXED-WIDTH plaintext. AEAD ciphertext is plaintext-length plus the tag, and
-//!     every field of a scan position varies in length, so a variable encoding would
-//!     make token LENGTH a side channel for the sealed row (a short name under a
-//!     short owner vs a long one) and for the candidate oid's width (40 hex on a
-//!     sha1 repo, 64 on a sha256 one). Every token this module mints is byte-identical
-//!     in length. Each field is padded to its own separate width, which is a per-field
-//!     constant and so still leaks nothing about a given row or candidate.
-//!   * The canonical CID as associated data, so a token minted while scanning for
-//!     one CID does not authenticate when replayed against another.
-//!
-//! Every failure to open (wrong key, tampered bytes, wrong CID, expired, malformed)
-//! returns the same `None`. The caller treats that as "no token" and starts at the
-//! front, so no failure class is distinguishable and the token is no oracle.

-//!
-//! Deliberately narrow: the ANS-104 codec lives in `ans104`, and the
-//! gateway probe, the `verify_anchor` path, and the public verify
-//! endpoint are deferred until the uploader, retrieval proof, and
-//! recovery consumer can be proven as one vertical slice (reviewer 2,

-//! upload/read pair, redirect-safe client, envelope-supplying read
-//! API, provider-documented absence evidence — belongs in that slice,
-//! not here. What ships here is the policy type plus the rule that
-//! only `DefinitivelyAbsent` permits spending another upload.

-//! The publication boundary: WHO wrote, and HOW FAR that write got.
-//!
-//! Four lifecycle defects on this branch shared one root cause. A resource was
-//! tracked by a coarse state — "release started", "the path exists", "a row with
-//! this name exists" — when the safety question was about the IDENTITY and the
-//! PUBLICATION STAGE of one specific write attempt. A tail replicated refs from
-//! an attempt that had not dispatched a PUT; a read served a tree whose
-//! generation nobody had confirmed; a fork claimed a concurrent attempt's row and
-//! deleted a successor's object; a response-loss failure was compensated as if it
-//! proved non-publication.
-//!
-//! This module is the vocabulary that makes those questions answerable, and it is
-//! deliberately free of any object-storage type:
-//!
-//! - [`PublishAttemptId`] — minted before the request is built, carried with the
-//!   bytes as user metadata, read back off the store to decide whether what is
-//!   published is THIS attempt's work.
-//! - [`PublishStage`] / [`PublishStageCell`] — how far one attempt got, observable
-//!   from outside the future that is performing it, so a CANCELLED attempt can
-//!   still be classified.
-//! - [`UploadError`] — what the client KNOWS about dispatch and commit, not just
-//!   which HTTP status came back. Destructive compensation is licensed only by
-//!   [`UploadError::proves_not_published`].
-//!
-//! # Porting note (#79)
-//!
-//! PR #79 (`feat/storage-abstraction`) deletes `git/tigris.rs` and replaces it
-//! with a `BlobStore`/`RepoArchive` layer. Everything in this file is
-//! backend-agnostic on purpose and is meant to survive that swap unchanged: a new
-//! backend supplies its own error classifier (the one in `tigris.rs` is a single
-//! private function) and keeps these types as the contract its callers read.
