fix(node): drop withheld-subtree trees from the replication pin set - #382
Merged
Merged
Conversation
A tree reachable only under a denied path survived both pin filters because trees were never in the blob universe, so public IPFS still learned child filenames and blob oids. Filter trees the same way as blobs on the delta withheld set and the full-scan allow-list. Closes #172.

…e#26 split 1/4) This is the handler-level half of Split PR 1. The previous commit added the migration and the DB methods; this one threads them through crates/gitlawb-node/src/api/repos.rs:2007 (git_receive_pack), the cert issuer, and the startup drain. CHANGES IN THE HANDLER ====================== In git_receive_pack, AT THE LAST POSSIBLE MOMENT before the smart_http::receive_pack call, the handler now: 1. Generates a per-handler request_id (UUID). 2. Captures the raw Signature, Signature-Input, and Content-Digest headers from the request. 3. Calls db.insert_pending_ref_transitions(request_id, ...) which writes one row per ref update in state 'prepared'. The receive_pack call runs as before. After it returns: 4. On Ok: db.mark_pending_ref_transitions_applied(request_id) — the row is the ONLY thing that promotes a 'prepared' row to 'applied', and the drain reads only 'applied' rows. A process crash before this call leaves the row in 'prepared', which the drain never promotes. 5. On Err: db.mark_pending_ref_transitions_cancelled(request_id) — a failed receive_pack leaves the row in 'cancelled', which the drain never promotes. This is what closes the reviewer's two proofs: Proof 1 (crash window): if the process dies after mark_pending_ref_transitions_applied but before the bookkeeping writes, the row is in 'applied' and the next startup drain re-derives the push event, the per-ref certificate (carrying the ORIGINAL pusher DID, not a placeholder), and the anchor handoff. The drain uses the persisted authentic pusher DID and signature header, not a recovered placeholder. Proof 2 (failed receive-pack): the row is only ever flipped to 'applied' in the explicit Ok branch above. A 'prepared' or 'cancelled' row is invisible to the drain, so a failed or dropped receive_pack cannot turn a prepared intent into completed accounting or anchoring. BOOKKEEPING IS NOW DETERMINISTIC-ID =================================== The post-Ok bookkeeping at api/repos.rs:2448 now uses: - record_push_with_id with push_event_id_for(request_id, first_ref) — ON CONFLICT (id) DO NOTHING, so a recovery re-pass is a no-op. - issue_ref_certificate_idempotent with ref_cert_id_for(request_id, ref_name) — ON CONFLICT (repo_id, ref_name) DO NOTHING, returns None if a live-path cert already exists. - insert_anchor_job_idempotent with anchor_job_id_for(repo_id, ref_name, old_sha, new_sha) — the per-transition tuple key, so two pushes to the same ref produce one anchor upload per landed state. The legacy entry points (record_push, issue_ref_certificate, insert_ref_certificate) remain for callers that prefer a fresh UUID per cert; they are #[allow(dead_code)] for the PR 3 cert/CLI compat pass to decide whether to keep or remove. STARTUP DRAIN ============= crates/gitlawb-node/src/main.rs calls durable_outbox::drain_pending_ref_transitions(state, 1000) ONCE before serving, after migrations and after the existing peer / quarantine prunes. Non-fatal: a transient drain failure logs and leaves the rows for the next startup. durable_outbox::drain_pending_ref_transitions reads every 'applied' row, calls derive_one (which re-derives the three artifacts using the persisted authentic pusher DID and signature header), then deletes the row. A second drain pass is a no-op for both the artifacts (idempotent inserts) and the row (gone after the first pass). NEW END-TO-END TESTS ==================== crates/gitlawb-node/src/durable_outbox.rs adds three end-to-end tests in drain_tests, complementing the eight DB-layer tests in db::pending_ref_transition_tests: - drain_re_derives_all_three_artifacts_for_an_applied_row: the reviewer's first proof. Inserts a row in 'applied' state (the crash window), drains, asserts exactly one push event row, exactly one cert row carrying the original pusher DID (not a placeholder), and exactly one anchor job row. Asserts the deterministic cert id matches. Asserts a second drain pass is a no-op. - cancelled_row_produces_no_artifacts: the reviewer's second proof for the cancelled state. A row in 'cancelled' (receive_pack returned Err) is invisible to the drain. - prepared_row_produces_no_artifacts: the reviewer's second proof for the prepared state. A row in 'prepared' (handler crashed between insert_prepared and the post-Ok branch) is invisible to the drain. Each test names the invariant it pins and the production line it covers. Reverting that line turns the named assertion red. Compiles clean, 1099 tests pass with 0 regressions, clippy clean under -D warnings, fmt clean. Cross-PR overlap (declared in the PR description): - Twigpine#134 (anchors auth): composes. The /arweave/anchors route already requires auth; this PR does not change the route. - Twigpine#285 (advisory-lock session affinity): composes. The durable intent is written inside the same handler that holds the lock from Twigpine#285; no changes to the lock layer. - Twigpine#306 (Content-Digest on signed requests): composes. PR 1 persists the Content-Digest header that Twigpine#306 makes mandatory. - Twigpine#314 (small-order Ed25519): independent. PR 1's tests use strong keys. - Twigpine#324 (libp2p keypair persistence): independent. PR 1 does not touch p2p identity. - Twigpine#325 (gossip ref-update auth): independent. PR 1's signed envelope is the HTTP-side equivalent, not the gossip-side. - Twigpine#382 (replication withheld-subtree trees): independent. PR 1 does not touch replication or pin selection.

There was a problem hiding this comment.
The withheld-tree fix is correct and the invariant tests are the strong part: the combined blob-slice equals the old withheld_blob_oids, a dedup tree shared across allowed and denied paths stays replicable, a non-commit ref fails the walk closed, and the deliberate flip of fail_closed_keeps_nonblobs_and_allowed_blobs_only is justified by the premise being falsified. Sequencing note: replicable_objects_fail_closed changes signature here AND in #244, so those two need a coherent rebase (keep the tree-aware 5-arg form; do not drop a parameter on the way).

… 2/4) (Twigpine#524) * fix(node): ANS-104 transport, three-outcome probe, verify endpoint (Twigpine#26 split 2/4) Reviewer 2 closed PR Twigpine#224 on 2026-08-28 with a directive: split into four narrow PRs. This is Split PR 2 (Arweave transport and verification). The P1 finding the reviewer assigned to this split: the legacy `anchor_item_present` mapped `BAD_REQUEST` and `GONE` to `Ok(false)`, and the recovery code interpreted false as permission to reclaim the row and pay for another upload. Neither 400 nor 410 proves a previously paid item was never accepted: 410 can describe an artifact that existed but is no longer served, and 400 can be produced by gateway, proxy, or routing failure. The concrete failure sequence the reviewer named: bundler accepts the item, the response or terminal DB write is lost, recovery probes the persisted item_id, the gateway returns 400 or 410, and the node pays for a second immutable item for the same transition. Fix: model the probe result as three outcomes, and authorize a re-upload only on a trustworthy, protocol-defined absence. NEW MODULE crates/gitlawb-node/src/ans104.rs - DataItem: the on-wire ANS-104 shape (signature, owner, target, anchor, tags, data — all base64url-encoded except target/anchor). - deep_hash: the canonical signing input per the spec. The signature is over a SHA-256 mix of the dataitem/list/map discriminators, the signature type, owner, target, anchor, the recursively-hashed tag list, and the data payload. A hand-rolled sha256 of the JSON body would produce a hash no Arweave gateway would recognize; the deep-hash is the only correct form. - sign_data_item: Ed25519 over deep_hash. - verify_data_item: parses the owner, checks the signature against an expected pubkey, and reports a specific failure reason on each branch. - 7 unit tests covering round-trip, flipped signature, wrong expected key, mutated data, wire-shape round-trip, deep-hash stability, and the empty-tags edge case. NEW MODULE crates/gitlawb-node/src/arweave_v2.rs - ProbeOutcome: Present (2xx, body parses as ANS-104, sig verifies), DefinitivelyAbsent (404 with a known JSON body shape), Indeterminate (everything else). The reviewer's three-outcome model. - ProbeOutcome::permits_reupload: the recovery policy. ONLY DefinitivelyAbsent authorizes a paid re-upload. Indeterminate keeps the outbox non-terminal; Present skips re-payment. - probe_anchor_item: the gateway probe. 2xx bound to a different item id is Indeterminate, not Present. 2xx with a body that does not parse as ANS-104 is Indeterminate. Oversized bodies are Indeterminate (defense against body-stuffing). - read_capped_body: enforces PROBE_MAX_BODY_BYTES (1 MiB) on the full body, with a Content-Length fast-path that rejects before reading. - verify_anchor: the full path the public verify endpoint takes. Fetches the data item, parses it, verifies the Ed25519 signature against the persisted node_did, decodes the data payload as JSON, and reports the result. - 15 unit tests pinning each classification boundary: 400/410/5xx/transport/2xx-non-json/2xx-bad-sig/2xx-different- owner are all Indeterminate; 404 with empty or known-JSON body is DefinitivelyAbsent; 2xx with a valid signed item is Present; the re-upload policy is exhaustive. NEW DB METHOD crates/gitlawb-node/src/db/mod.rs - get_arweave_anchor_by_item_id: looks up an existing arweave_anchors row by its id (which is the Irys tx id, the same value the Arweave gateway uses to serve the data item). Used by the public verify endpoint to fetch the persisted node_did so the envelope signature can be verified against it. NEW CONFIG crates/gitlawb-node/src/config.rs - GITLAWB_ARWEAVE_GATEWAY_URL: the Arweave gateway the probe reads from. Defaults to https://arweave.net; operators can point it at a private mirror. NEW HTTP ENDPOINT crates/gitlawb-node/src/api/arweave.rs - GET /api/v1/arweave/anchors/verify/{item_id}: the public verify endpoint. Returns {item_id, status, verified, owner_did, data_payload, error} where status is one of "verified" / "definitively_absent" / "indeterminate". - 3 endpoint-level tests covering the verified, 404, and 400 shapes via the live router, asserting the public surface surfaces the three outcomes. WIRE-UP crates/gitlawb-node/src/server.rs - The verify route is registered alongside the existing /api/v1/arweave/anchors list route. NOT IN THIS SLICE (the bundler upload, the next commit): - The handler that builds a DataItem from a ref-cert and POSTs it to the bundler is not in this PR. The ANS-104 module is ready to be called by it; the cert/push-event flow in PR 1 persists the row that the bundler upload would consume. - PR 1's recovery drain produces an `anchor_jobs` row keyed on the (repo, ref, old, new) tuple; the next slice reads that row, builds the ANS-104 data item, POSTs to the bundler, and writes the resulting tx id to arweave_anchors. Compiles clean, 1113 tests pass with 0 regressions, clippy clean under -D warnings, fmt clean. Cross-PR overlap (declared in the PR description): - Twigpine#134 (anchors auth): composes. The verify endpoint reads from arweave_anchors; Twigpine#134's auth layer applies unchanged. The probe model is server-side and unauthenticated by design. - Twigpine#285 (advisory-lock session affinity): independent. The probe is read-only. - Twigpine#306 (Content-Digest on signed requests): independent. The probe does not sign requests. - Twigpine#314 (small-order Ed25519): composes. The verify path calls Did::to_verifying_key which already enforces the small-order check from Twigpine#314. - Twigpine#324 (libp2p keypair persistence): independent. - Twigpine#325 (gossip ref-update auth): independent. The verify path is for the public Arweave gateway, not gossip. - Twigpine#382 (replication withheld-subtree trees): independent. * fix(node): address reviewer findings on Twigpine#26 split 2/4 (transport) - P1 (DB lookup): get_arweave_anchor_by_item_id now filters on irys_tx_id (the externally-routable item id) rather than the internal UUID primary key. The production writer stores a fresh UUID in `id` and the Irys response / ANS-104 derived id in `irys_tx_id`; the old filter would always 404. New integration tests exercise the production writer path with distinct values for the two columns. - P1 (verify-gate): verify_anchor now gates on repo read via authorize_repo_read. The route is split in server.rs: the public list_anchors stays ungated (Twigpine#134 tracks that surface), the verify route gets optional_signature per the team memory `axum-layer-vs-merge-pitfall.md`. Denials on row-lookup, gate, and missing repo all collapse to the same opaque 404 so the public endpoint does not leak anchor-row existence. - P1 (ANS-104 deep-hash): rewritten to the verified SHA-384 recursive list/blob algorithm (matches `arbundles` JS reference). deep_hash returns [u8; 48]; signature is over the raw 48-byte digest. Three reference vectors from `Irys-xyz/arbundles/src/__tests__/deepHash.spec.ts` are bit-exact-asserted as the interop canary per the team memory `self-roundtrip-tests-do-not-prove-interop.md`. - P1 (artifact-identity): v2 verify now derives the protocol id via DataItem::id() (base64url(SHA256(signature))) and requires equality with the requested URL item_id. A node key signs many data items, so a valid signature only proves who signed the response — not that the served item is the one the caller asked to verify. The team memory `verify-against-artifact-id-not-signer.md` is the policy. - P1 (verifier can't read this head's writes): verify_anchor now accepts BOTH the v2 ANS-104 format and the v1 raw-JSON shape the live path on this branch actually writes. The v1 path does a field-equality check on repo, ref_name, old_sha, new_sha, node_did against the persisted row (no signature in v1; Irys storage plus the JSON parse are the integrity guarantee). - P2 (ProbeOutcome in result): AnchorVerifyResult now carries outcome: ProbeOutcome. The HTTP handler maps the structured field to the status string instead of parsing the human- readable error message — any future wording change in arweave_v2.rs can no longer silently reclassify a DefinitivelyAbsent as Indeterminate. - P2 (empty 404 body): classify_404 returns Indeterminate for bodyless 404s. The team memory `distinguish-unknown-from-empty.md` is the policy: a bodyless 404 from a proxy is not a proof of absence, and the recovery policy (permits_reupload -> true on DefinitivelyAbsent) authorizes a paid, irreversible re-upload. - P2 (streaming cap): read_capped_body no longer uses resp.bytes() (which buffers the full response before checking size). It now reads chunk-by-chunk and aborts the moment the cumulative byte count crosses the cap, so a chunked response without Content-Length cannot force unbounded allocation. * fix(node): address three reviewer findings on Twigpine#26 split 2/4 (round 2) * fix(node): address five reviewer findings on Twigpine#26 split 2/4 (round 3) * fix(node): address reviewers round-4 on Twigpine#26 split 2/4 (interop) * fix(node): address coderabbit on Twigpine#26 split 2/4 (raw tags, vint overflow, golden key) * fix(node): enforce artifact-id in probe_item on Twigpine#26 split 2/4 * fix(node): require expected owner for probe Present on Twigpine#26 split 2/4 * fix(node): narrow Twigpine#26 split 2/4 to codec and policy types * fix(node): silence dead-code for deferred slice API on Twigpine#26 split 2/4 * fix(node): doc and bounds-check cleanup in ans104 on Twigpine#26 split 2/4 * docs(node): point tests doc at Ed25519 golden script on Twigpine#26 split 2/4 * fix(node): strict owner lengths, sign-before-hash on Twigpine#26 split 2/4 * fix(node): keep ans104 tags and field widths consistent on hash and encode DataItem keeps both the decoded `tags` and the original Avro `raw_tags`, both public. After a parse, changing `tags` left deep_hash and verify_data_item using the stale raw bytes, and to_binary wrote a header tag count that no longer matched the payload, so the frame failed to parse back. Take the tag block for hashing and encoding from one helper that decodes `raw_tags` and requires it to equal `tags`, and fail closed otherwise. The header count comes from the same validated pairs. Parsed multi-block and size-prefixed items still re-encode byte-exact and keep their signatures. deep_hash now also rejects a non-empty target or anchor that is not 32 bytes, as to_binary already does, so sign_data_item fails instead of signing an item that cannot be encoded. The legacy non-base64url anchor fallback is kept. The module and signature-type docs now say binary parsing accepts sigtypes 1 to 4 while signing and verifying are Ed25519 only on this slice. * build(scripts): declare the golden script's direct npm dependencies ans104_golden_ed25519.mjs imports bs58, @noble/ed25519 and base64url, and ans104_golden.mjs imports base64url, but package.json listed only arbundles, so they resolved only through hoisting. Declare them at the versions already locked, update the lockfile root entry (no resolved version or hash changes), and note the regeneration command in the golden output file. --------- Co-authored-by: Gravirei <gravirei@users.noreply.github.com>

A tree that exists only under a denied path no longer gets pinned to public IPFS or Pinata. The replication filters treated trees as structural, so a public CID still named child files and blob oids.
This is the write-side of the same withhold #173 already applies on GET /ipfs/{cid}.
Motivation & context
Closes #172.
Kind of change
What changed
gitlawb-node:replication_withheld_setnow walks blobs and withheld-subtree trees together. All three delta pin sites already take that set, including a first push, which runsrev-list --objectswithout--not.fail_closed_keeps_nonblobs_and_allowed_blobs_onlyis flipped on purpose. Its premise (trees are never content-withheld) was falsified by GET /ipfs/{cid} serves tree/commit objects of withheld subtrees, leaking structure get_tree protects (KTD3) #135/fix(node): gate GET /ipfs/{cid} tree objects so a withheld subtree's structure can't leak (#135) #173. Kubo and Pinata still consume the already-filtered list; there is no second filter.How a reviewer can verify
cargo test -p gitlawb-node --bin gitlawb-node --locked -- \ fail_closed_keeps_commits_allowed_blobs_and_allowed_trees_only \ withheld_object_set_contains_withheld_subtree_tree \ first_push_delta_drops_withheld_subtree_tree \ full_scan_drops_withheld_and_dangling_trees \ withheld_object_walk_fails_closed_on_non_commit_ref \ full_scan_shares_one_deadline_with_tree_allowed_set_walkThe first-push and full-scan tests assert the secret tree is in the candidate universe before they assert it is dropped. Reverting the tree clauses, swapping the wrapper back to blob-only, dropping the non-commit-ref guard, or handing the later full-scan phases a fresh timeout each goes red.

Already-pinned withheld trees stay on public IPFS/Pinata until unpin or GC. This PR stops new pins only. Distinct from #136 and from #218 / #244.
Live only when
GITLAWB_IPFS_APIorGITLAWB_PINATA_JWTis set; both default empty.Does not change git upload-pack. A path-scoped clone still receives withheld-subtree trees.
Parent allowed trees still name withheld children. That is the SHA-intact tradeoff, same as
get_tree.replicable_objectsstill trusts the withheld set it is handed. A future blob-only set would reopen this class. Production delta sites all go throughreplication_withheld_set.#244 touches the same files and will need a rebase onto this.
