From c1706ca6238174758d6f1524c6ec953bdd1868ee Mon Sep 17 00:00:00 2001 From: Data Date: Wed, 3 Jun 2026 00:44:25 +0200 Subject: [PATCH 01/39] feat(holograph): scaffold crate with SpaceConfig + CBOR envelope (Step 0.5) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit New `rust-executor/crates/holograph` crate added as workspace member. Modules: - `config`: `SpaceConfig` with `ArcPolicy`, `LocFnPolicy`, `ValidationRegime`, and `gossip_initiate_interval_ms`. `full_replication_single_doc()` is the v1 default and is also the `Default` impl. Honors sharding-ready commitments 1, 2, 6 from SPIKE.md §1.5 (DhtArc-aware, loc-fn policy wired, space takes config struct). - `envelope`: `OpEnvelope` CBOR-encoded via ciborium with optional `doc_id` field. Honors commitment 3 — `#[serde(default, skip_serializing_if)]` keeps v1 envelopes (no `doc_id`) interop-compatible with v1.5 readers. Op-ids are raw bytes on the wire rather than going through `kitsune2_api::OpId`'s base64-string serde (which requires borrowed `&str` deserialization that CBOR cannot provide). Tests cover SpaceConfig defaults, ArcPolicy round-trip, envelope round-trip with/without doc_id, legacy-envelope forward-compat, and malformed-bytes error path. --- Cargo.lock | 38 +++++ Cargo.toml | 1 + rust-executor/crates/holograph/Cargo.toml | 18 +++ rust-executor/crates/holograph/src/config.rs | 140 ++++++++++++++++ .../crates/holograph/src/envelope.rs | 150 ++++++++++++++++++ rust-executor/crates/holograph/src/lib.rs | 16 ++ 6 files changed, 363 insertions(+) create mode 100644 rust-executor/crates/holograph/Cargo.toml create mode 100644 rust-executor/crates/holograph/src/config.rs create mode 100644 rust-executor/crates/holograph/src/envelope.rs create mode 100644 rust-executor/crates/holograph/src/lib.rs diff --git a/Cargo.lock b/Cargo.lock index d3f2f73f5..8fce81b4f 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -2214,6 +2214,33 @@ dependencies = [ "windows-link 0.2.1", ] +[[package]] +name = "ciborium" +version = "0.2.2" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "42e69ffd6f0917f5c029256a24d0161db17cea3997d185db0d35926308770f0e" +dependencies = [ + "ciborium-io", + "ciborium-ll", + "serde", +] + +[[package]] +name = "ciborium-io" +version = "0.2.2" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "05afea1e0a06c9be33d539b876f1ce3692f4afea2cb41f740e7743225ed1c757" + +[[package]] +name = "ciborium-ll" +version = "0.2.2" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "57663b653d948a338bfb3eeba9bb2fd5fcfaecb9e199e87e1eda4d9e8b240fd9" +dependencies = [ + "ciborium-io", + "half 2.7.1", +] + [[package]] name = "cid" version = "0.10.1" @@ -8996,6 +9023,17 @@ dependencies = [ "uuid 1.18.1", ] +[[package]] +name = "holograph" +version = "0.1.0" +dependencies = [ + "bytes", + "ciborium", + "kitsune2_api", + "serde", + "thiserror 2.0.18", +] + [[package]] name = "home" version = "0.5.12" diff --git a/Cargo.toml b/Cargo.toml index 905f7f44c..259ab173f 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -4,6 +4,7 @@ members = [ "cli", "rust-client", "rust-executor", + "rust-executor/crates/holograph", "ui/src-tauri" ] diff --git a/rust-executor/crates/holograph/Cargo.toml b/rust-executor/crates/holograph/Cargo.toml new file mode 100644 index 000000000..6bdd18709 --- /dev/null +++ b/rust-executor/crates/holograph/Cargo.toml @@ -0,0 +1,18 @@ +[package] +name = "holograph" +version = "0.1.0" +edition = "2021" +authors = ["Nicolas Luck "] +description = "AD4M Holograph substrate — Kitsune2-backed link-language plumbing" +license = "CAL-1.0" + +[lib] +name = "holograph" +path = "src/lib.rs" + +[dependencies] +bytes = "1" +ciborium = "0.2" +kitsune2_api = { git = "https://github.com/holochain/kitsune2.git", rev = "320a4d9e622c5f1a6f22d29c8beeb0cb5c333cc3" } +serde = { version = "1", features = ["derive"] } +thiserror = "2" diff --git a/rust-executor/crates/holograph/src/config.rs b/rust-executor/crates/holograph/src/config.rs new file mode 100644 index 000000000..928c72f0e --- /dev/null +++ b/rust-executor/crates/holograph/src/config.rs @@ -0,0 +1,140 @@ +//!

The only `T` the algorithm ever fetched was `PerspectiveDiffEntryReference`, so those methods are now concretely typed to return it — no generic, no bound. - `ScopedEntryDefIndex/EntryVisibility/Entry: TryFrom/WasmError: From` on `create_entry`. The fn now takes the `EntryTypes` integrity-zome union directly; all call sites already passed `EntryTypes::Foo(…)`. The `HolochainRetreiver` impl still uses HDK internally (decodes via `to_app_option::()`, calls the HDK host `create_entry`). The trait surface itself no longer imposes HDK conversions, so the upcoming `KitsuneRetreiver` (Step 2) and the in-process `MockPerspectiveGraph` can implement it without inheriting the HDK type machinery through the trait. Call-site updates are mechanical: `Retriever::get::(h)` becomes `Retriever::get(h)` across `lib.rs`, `link_adapter/{commit,pull,chunked_diffs}.rs`, and the mock test fixtures. All 36 `perspective_diff_sync` unit tests stay green. --- .../zomes/perspective_diff_sync/src/lib.rs | 3 +- .../src/link_adapter/chunked_diffs.rs | 19 +++++--- .../src/link_adapter/commit.rs | 22 +++++---- .../src/link_adapter/pull.rs | 4 +- .../perspective_diff_sync/src/retriever.rs | 47 ++++++++++++------- .../src/retriever/holochain.rs | 29 ++++-------- .../src/retriever/mock.rs | 38 ++++++--------- 7 files changed, 81 insertions(+), 81 deletions(-) diff --git a/bootstrap-languages/p-diff-sync/hc-dna/zomes/perspective_diff_sync/src/lib.rs b/bootstrap-languages/p-diff-sync/hc-dna/zomes/perspective_diff_sync/src/lib.rs index 580a843e1..bc67127d3 100644 --- a/bootstrap-languages/p-diff-sync/hc-dna/zomes/perspective_diff_sync/src/lib.rs +++ b/bootstrap-languages/p-diff-sync/hc-dna/zomes/perspective_diff_sync/src/lib.rs @@ -219,8 +219,7 @@ pub fn get_others(_: ()) -> ExternResult> { #[hdk_extern] pub fn get_diff_entry_reference(hash: Hash) -> ExternResult { use retriever::PerspectiveDiffRetreiver;

This commit lands the *foundation* of the extraction — the trait abstractions plus a first migrated module — and explicitly narrows the broader move per SPIKE.md §2.6 ("narrow the move") and risk-register guidance. The remaining link_adapter modules (`workspace`, `chunked_diffs`, `revisions`, `snapshots`, `render`, `pull`, `commit`) stay in p-diff-sync for now; see `.spike-status/step-1.5-status.md` for the deferred-work list and rationale. What lands: - `crates/perspective-diff-algorithm/`: * `OpId` marker trait — Clone+Eq+Ord+Hash+Debug+Display+Serialize+ DeserializeOwned+Send+Sync+'static. Blanket-impl'd so any conforming type (e.g. `HoloHash`, `kitsune2_api::OpId`) is automatically an `OpId`. * `HasDiffParents` trait — the only structural property the DAG-walk algorithms need from a node type. Lets the algorithm crate stay ignorant of whether the node is `PerspectiveDiffEntryReference` or something else. * `topo_sort_diff_references` — Kahn's algorithm, generic over `(O: OpId, V: HasDiffParents)`. Moved verbatim from `p-diff-sync::link_adapter::topo_sort`. Has its own substrate-independent tests (linear chain, diamond, no-root, missing-parent), all green. - `perspective_diff_sync_integrity`: * New dep on `perspective-diff-algorithm`. * `HasDiffParents>` impl on `PerspectiveDiffEntryReference`. Lives here (not p-diff-sync) because both the trait and the type are foreign to p-diff-sync; the orphan rule forces this placement. - `perspective_diff_sync`: * New dep on `perspective-diff-algorithm`. * `link_adapter::topo_sort` is now a thin Holochain-side adapter that delegates into the algorithm crate and maps `TopoSortError` -> `SocialContextError` for backwards compatibility. All call sites and the existing `test_topo_sort` test are unchanged on the outside. Tests: - `cargo test --release -p perspective-diff-algorithm -- --test-threads=1` — 4 tests pass (linear, diamond, no-root, missing-parent). - `cargo test -p perspective_diff_sync --lib -- --test-threads=1` — 36 tests pass (chunked_diffs, pull, topo_sort, workspace, mock-graph). - `cargo build --release -p holograph` clean. --- Cargo.lock | 8 + Cargo.toml | 1 + .../p-diff-sync/hc-dna/Cargo.lock | 10 + .../zomes/perspective_diff_sync/Cargo.toml | 1 + .../src/link_adapter/topo_sort.rs | 132 +++-------- .../Cargo.toml | 1 + .../src/lib.rs | 13 ++ crates/perspective-diff-algorithm/Cargo.toml | 15 ++ crates/perspective-diff-algorithm/src/lib.rs | 71 ++++++ .../src/topo_sort.rs | 210 ++++++++++++++++++ 10 files changed, 364 insertions(+), 98 deletions(-) create mode 100644 crates/perspective-diff-algorithm/Cargo.toml create mode 100644 crates/perspective-diff-algorithm/src/lib.rs create mode 100644 crates/perspective-diff-algorithm/src/topo_sort.rs diff --git a/Cargo.lock b/Cargo.lock index 8fce81b4f..725b6ed42 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -14398,6 +14398,14 @@ version = "2.3.2" source = "registry+https://github.com/rust-lang/crates.io-index" checksum = "9b4f627cb1b25917193a259e49bdad08f671f8d9708acfd5fe0a8c1455d87220" +[[package]] +name = "perspective-diff-algorithm" +version = "0.1.0" +dependencies = [ + "serde", + "thiserror 1.0.69", +] + [[package]] name = "pest" version = "2.8.6" diff --git a/Cargo.toml b/Cargo.toml index 259ab173f..d8baad43f 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -2,6 +2,7 @@ resolver = "2" members = [ "cli", + "crates/perspective-diff-algorithm", "rust-client", "rust-executor", "rust-executor/crates/holograph", diff --git a/bootstrap-languages/p-diff-sync/hc-dna/Cargo.lock b/bootstrap-languages/p-diff-sync/hc-dna/Cargo.lock index dd65ed2c9..ca726a317 100644 --- a/bootstrap-languages/p-diff-sync/hc-dna/Cargo.lock +++ b/bootstrap-languages/p-diff-sync/hc-dna/Cargo.lock @@ -5421,6 +5421,14 @@ version = "2.3.2" source = "registry+https://github.com/rust-lang/crates.io-index" checksum = "9b4f627cb1b25917193a259e49bdad08f671f8d9708acfd5fe0a8c1455d87220" +[[package]] +name = "perspective-diff-algorithm" +version = "0.1.0" +dependencies = [ + "serde", + "thiserror 1.0.69", +] + [[package]] name = "perspective_diff_sync" version = "0.0.1" @@ -5437,6 +5445,7 @@ dependencies = [ "js-sys", "lazy_static", "maplit", + "perspective-diff-algorithm", "perspective_diff_sync_integrity", "petgraph", "serde", @@ -5454,6 +5463,7 @@ dependencies = [ "hdk", "holo_hash", "holochain_serialized_bytes", + "perspective-diff-algorithm", "serde", ] diff --git a/bootstrap-languages/p-diff-sync/hc-dna/zomes/perspective_diff_sync/Cargo.toml b/bootstrap-languages/p-diff-sync/hc-dna/zomes/perspective_diff_sync/Cargo.toml index 3e707bd28..54af16256 100644 --- a/bootstrap-languages/p-diff-sync/hc-dna/zomes/perspective_diff_sync/Cargo.toml +++ b/bootstrap-languages/p-diff-sync/hc-dna/zomes/perspective_diff_sync/Cargo.toml @@ -20,6 +20,7 @@ graphviz-rust = "0.9.6" dot-structures = "0.1.0" itertools = "0.10.3" perspective_diff_sync_integrity = { path = "../perspective_diff_sync_integrity" } +perspective-diff-algorithm = { path = "../../../../../crates/perspective-diff-algorithm" } sha2 = "0.10.5" #getrandom = { version = "0.2", features = ["js"] } getrandom = { version = "0.3" } diff --git a/bootstrap-languages/p-diff-sync/hc-dna/zomes/perspective_diff_sync/src/link_adapter/topo_sort.rs b/bootstrap-languages/p-diff-sync/hc-dna/zomes/perspective_diff_sync/src/link_adapter/topo_sort.rs index 0b2c891a9..1f6276671 100644 --- a/bootstrap-languages/p-diff-sync/hc-dna/zomes/perspective_diff_sync/src/link_adapter/topo_sort.rs +++ b/bootstrap-languages/p-diff-sync/hc-dna/zomes/perspective_diff_sync/src/link_adapter/topo_sort.rs @@ -1,108 +1,44 @@ +//!

Persistence-not-optional per SPIKE §0: the load-bearing `state_persists_across_reopen` test closes the db handle, reopens at the same path, and verifies stored ops + op-ids round-trip. The `bob_asks_alice_alice_serves` smoketest exercises the `process_incoming_ops -> retrieve_ops -> process_incoming_ops` round-trip end-to-end between two store instances (SPIKE §2.5 exit check, lite version — no DynSpace involved here, just the OpStore surface). Storage shape: - `ops`: `op_id_bytes -> ciborium-encoded OpRecord {created_at_micros, stored_at_micros, op_data}`. No secondary time indexes; v1 scale doesn't need them, query methods scan + filter. - `slice_hashes`: composite key `arc_prefix(9) || slice_id_be(8)`. The arc prefix lets us prefix-scan all slices for a given arc in one cursor pass. Envelope decoding is injected as a closure (`EnvelopeDecoder`) at construction time — keeps the OpStore generic-free and lets HolographSpace (Step 4) own envelope semantics while letting tests use deterministic test-only decoders. Sharding-ready commitment 1 (SPIKE §1.5) honored in `process_incoming_ops`: the arc-policy is consulted before storing rather than hardcoding "yes." v1 `Full` arc lets everything through; v1.5 sharded mode filters here without further code changes. 16 tests pass (7 prior + 9 new KvOpStore tests covering round-trip, dedup, filter, time-slice query, earliest-timestamp, slice-hash round-trip, empty-hash rejection, restart persistence, Bob-asks-Alice). --- Cargo.lock | 151 ++-- rust-executor/crates/holograph/Cargo.toml | 8 + rust-executor/crates/holograph/src/lib.rs | 2 + .../crates/holograph/src/op_store.rs | 693 ++++++++++++++++++ 4 files changed, 811 insertions(+), 43 deletions(-) create mode 100644 rust-executor/crates/holograph/src/op_store.rs diff --git a/Cargo.lock b/Cargo.lock index 725b6ed42..7cc09c3f5 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -527,7 +527,7 @@ dependencies = [ "objc2-core-foundation", "objc2-core-graphics", "objc2-foundation", -

Bridges three things: - **Sync trait, async store**: the `PerspectiveDiffRetreiver` methods are static-sync; K2's `OpStore` returns `BoxFuture`. The retriever state owns a *dedicated* `tokio::runtime::Runtime` (built with `new_multi_thread().worker_threads(2)`) and every async K2 call goes through `runtime.block_on(...)`. This is the SPIKE §2.6 tokio-nesting mitigation — `block_on` runs on the *caller's* thread (the sync algorithm thread), so the inner runtime's worker threads are always distinct from it; no deadlock. - **Static method, per-substrate state**: matches the existing `HolochainRetreiver`/`MockPerspectiveGraph` pattern by stashing state in a process-global `RwLock>>` slot. `install()` is one-shot in production; tests use `reset_for_test` + a `Mutex` for serialization. - **Hash <-> OpId mapping + envelope decoding**: `Hash` (= 36-byte `HoloHash`) maps 1:1 to `kitsune2_api::OpId` via the raw 36 bytes. The op-id is `sha256(envelope.payload) || [0xdb;4]` so the same serialized `PerspectiveDiffEntryReference` always hashes to the same id — matching `MockPerspectiveGraph::create_entry`'s scheme. OpEnvelope grows a `created_at_micros: i64` field (default 0 for backward compatibility) so peers derive identical timestamps from identical envelope bytes. `OpEnvelope::new_at` is the explicit-timestamp constructor; `new` keeps existing call sites unchanged. Holograph crate now depends on `perspective_diff_sync`, `perspective_diff_sync_integrity`, `hdk`, `holo_hash`, and `holochain_serialized_bytes` (path/git deps). Per the orchestrator's Option A (see `.spike-status/blocker-step-1.5.md`), accepting this transitive HDK pull for the spike is preferred over blocking on the deeper data-type extraction. `perspective_diff_sync`'s `errors` and `retriever` modules promoted from `mod` to `pub mod` so external crates can `use` the trait and error types. No semantic changes to the modules themselves. 20 tests pass (16 prior + 4 new KitsuneRetreiver tests covering create+get round-trip, deterministic hashing, revisions round-trip, and get_with_timestamp accuracy). --- Cargo.lock | 118 ++++- .../zomes/perspective_diff_sync/src/lib.rs | 6 +- rust-executor/crates/holograph/Cargo.toml | 13 + .../crates/holograph/src/envelope.rs | 26 + rust-executor/crates/holograph/src/lib.rs | 2 + .../crates/holograph/src/retriever_kitsune.rs | 470 ++++++++++++++++++ 6 files changed, 630 insertions(+), 5 deletions(-) create mode 100644 rust-executor/crates/holograph/src/retriever_kitsune.rs diff --git a/Cargo.lock b/Cargo.lock index 7cc09c3f5..88295c6d2 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -5609,6 +5609,21 @@ dependencies = [ "tendril 0.5.0", ] +[[package]] +name = "dot-generator" +version = "0.2.0" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "0aaac7ada45f71873ebce336491d1c1bc4a7c8042c7cea978168ad59e805b871" +dependencies = [ + "dot-structures", +] + +[[package]] +name = "dot-structures" +version = "0.1.2" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "498cfcded997a93eb31edd639361fa33fd229a8784e953b37d71035fe3890b7b" + [[package]] name = "dotenvy" version = "0.15.7" @@ -6525,6 +6540,12 @@ version = "0.1.9" source = "registry+https://github.com/rust-lang/crates.io-index" checksum = "5baebc0774151f905a1a2cc41989300b1e6fbb29aff0ceffa1064fdd3088d582" +[[package]] +name = "fixedbitset" +version = "0.4.2" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "0ce7134b9999ecaf8bcd65542e436736ef32ddca1b3e06094cb6ec5755203b80" + [[package]] name = "fixedbitset" version = "0.5.7" @@ -7665,6 +7686,22 @@ dependencies = [ "bitflags 2.9.4", ] +[[package]] +name = "graphviz-rust" +version = "0.9.8" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "dee83cefff83c5dd5f34c603145f4e8d478e70cc17873049b6a36eeaf37b250a" +dependencies = [ + "dot-generator", + "dot-structures", + "into-attr", + "into-attr-derive", + "pest", + "pest_derive", + "rand 0.9.2", + "tempfile", +] + [[package]] name = "group" version = "0.12.1" @@ -9038,11 +9075,18 @@ name = "holograph" version = "0.1.0" dependencies = [ "bytes", + "chrono", "ciborium", "futures", + "hdk", + "holo_hash", + "holochain_serialized_bytes", "kitsune2_api", "once_cell", + "perspective_diff_sync", + "perspective_diff_sync_integrity", "serde", + "sha2 0.10.9", "sled", "tempfile", "thiserror 2.0.18", @@ -9822,6 +9866,28 @@ dependencies = [ "trilean", ] +[[package]] +name = "into-attr" +version = "0.1.1" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "18b48c537e49a709e678caec3753a7dba6854661a1eaa27675024283b3f8b376" +dependencies = [ + "dot-structures", +] + +[[package]] +name = "into-attr-derive" +version = "0.2.1" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "ecac7c1ae6cd2c6a3a64d1061a8bdc7f52ff62c26a831a2301e54c1b5d70d5b1" +dependencies = [ + "dot-generator", + "dot-structures", + "into-attr", + "quote", + "syn 1.0.109", +] + [[package]] name = "io-lifetimes" version = "1.0.11" @@ -14446,6 +14512,44 @@ dependencies = [ "thiserror 1.0.69", ] +[[package]] +name = "perspective_diff_sync" +version = "0.0.1" +dependencies = [ + "chrono", + "derive_more 0.99.20", + "dot-structures", + "getrandom 0.3.4", + "graphviz-rust", + "hdi", + "hdk", + "holochain_serialized_bytes", + "itertools 0.10.5", + "js-sys", + "lazy_static", + "maplit", + "perspective-diff-algorithm", + "perspective_diff_sync_integrity", + "petgraph 0.6.5", + "serde", + "sha2 0.10.9", + "thiserror 1.0.69", +] + +[[package]] +name = "perspective_diff_sync_integrity" +version = "0.0.1" +dependencies = [ + "chrono", + "derive_more 0.99.20", + "hdi", + "hdk", + "holo_hash", + "holochain_serialized_bytes", + "perspective-diff-algorithm", + "serde", +] + [[package]] name = "pest" version = "2.8.6" @@ -14489,13 +14593,23 @@ dependencies = [ "sha2 0.10.9", ] +[[package]] +name = "petgraph" +version = "0.6.5" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "b4c5cc86750666a3ed20bdaf5ca2a0344f9c67674cae0515bec2da16fbaa47db" +dependencies = [ + "fixedbitset 0.4.2", + "indexmap 2.11.1", +] + [[package]] name = "petgraph" version = "0.8.3" source = "registry+https://github.com/rust-lang/crates.io-index" checksum = "8701b58ea97060d5e5b155d383a69952a60943f0e6dfe30b04c287beb0b27455" dependencies = [ -

This proves the trait surface is substrate-agnostic — the same algorithm code that the existing `MockPerspectiveGraph` tests in p-diff-sync exercise also runs on the new Kitsune-backed substrate. Why not literally re-run the existing pdiff tests against KitsuneRetreiver: `MockPerspectiveGraph` derives hashes from DOT node-id strings via `node_id_hash`, while `KitsuneRetreiver` hashes by content (SHA-256 of the serialized `PerspectiveDiffEntryReference`). The test fixtures are not portable across hash schemes; the algorithm under test is. The parity tests reconstruct the same DAG shapes (linear chain, fork, merge node with two parents) and verify the same structural invariants (common-ancestor identification, entry-map completeness, parent walking) that the existing tests check. `commit`/`pull`/`render`/`get_snapshot` aren't covered here — they call HDK runtime fns directly (create_link/emit_signal/get_links/hash_entry) and stay HDK-bound per the Step 1.5 narrowing. The trait surface that KitsuneRetreiver implements *is* covered. Visibility tweaks: - `link_adapter::workspace` promoted from `pub(crate)` to `pub` so the parity tests can reach `Workspace::build_diffs`. No semantic change. - `KitsuneRetreiver::__clear_state_for_tests__` added as a `#[doc(hidden)]` escape hatch for integration-test crates; the `#[cfg(test)]`-only `reset_for_test` isn't reachable across the test-crate boundary. Tests: - `cargo test --release -p holograph -- --test-threads=1` — 20 unit + 4 integration = 24 tests pass. - `cargo test -p perspective_diff_sync --lib -- --test-threads=1` — 36 tests pass (HC-side unchanged). Combined: SPIKE.md §2.5 exit check #3 ("clean for pdiff-sync against both HolochainRetreiver AND KitsuneRetreiver") satisfied for the algorithm code paths the trait covers. --- .../src/link_adapter/mod.rs | 2 +- rust-executor/crates/holograph/Cargo.toml | 1 + .../crates/holograph/src/retriever_kitsune.rs | 9 + .../crates/holograph/tests/pdiff_parity.rs | 253 ++++++++++++++++++ 4 files changed, 264 insertions(+), 1 deletion(-) create mode 100644 rust-executor/crates/holograph/tests/pdiff_parity.rs diff --git a/bootstrap-languages/p-diff-sync/hc-dna/zomes/perspective_diff_sync/src/link_adapter/mod.rs b/bootstrap-languages/p-diff-sync/hc-dna/zomes/perspective_diff_sync/src/link_adapter/mod.rs index 385f55db2..a1a931a1a 100644 --- a/bootstrap-languages/p-diff-sync/hc-dna/zomes/perspective_diff_sync/src/link_adapter/mod.rs +++ b/bootstrap-languages/p-diff-sync/hc-dna/zomes/perspective_diff_sync/src/link_adapter/mod.rs @@ -7,4 +7,4 @@ pub(crate) mod snapshots; pub(crate) mod test_graphs; pub(crate) mod tests; pub(crate) mod topo_sort; -pub(crate) mod workspace; +pub mod workspace; diff --git a/rust-executor/crates/holograph/Cargo.toml b/rust-executor/crates/holograph/Cargo.toml index 6796f45f2..cc6bf135b 100644 --- a/rust-executor/crates/holograph/Cargo.toml +++ b/rust-executor/crates/holograph/Cargo.toml @@ -35,5 +35,6 @@ holo_hash = { version = "0.7.0-dev.6", git = "https://github.com/coasys/holochai holochain_serialized_bytes = "=0.0.56" [dev-dependencies] +once_cell = "1" tempfile = "3" tokio = { version = "1", features = ["rt", "rt-multi-thread", "sync", "macros", "time"] } diff --git a/rust-executor/crates/holograph/src/retriever_kitsune.rs b/rust-executor/crates/holograph/src/retriever_kitsune.rs index 9139e5d83..ae568bdab 100644 --- a/rust-executor/crates/holograph/src/retriever_kitsune.rs +++ b/rust-executor/crates/holograph/src/retriever_kitsune.rs @@ -189,6 +189,15 @@ impl KitsuneRetreiver { *slot = None; } + /// Reset the global state.

charset=UTF-8 Content-Transfer-Encoding: 8bit New `integration_queue` module — the K2-facing integration layer sitting above `KvOpStore`. K2's fetch path will hand inbound envelopes to the queue, not directly to the store; the queue owns sig-check, arc-filter, parent-presence, pend-or-store, and cascade-promote semantics. The store stays as the lowest-level decoder/persistence layer. Pipeline per inbound envelope: 1. Decode + signature verify (`SigVerifier`; v1 `AlwaysValid`). 2. Arc filter — sharding-ready commitment 1, consult `SpaceConfig.arc` policy; ops outside the local arc are dropped. 3. Dedup against op-store and pending tree (no double-store, no double-fetch). 4. Parent presence check via `KvOpStore::filter_out_existing_ops`: - all present → store + notify-up + cascade-promote pending children - some missing → pend in sled `pending` tree keyed by op-id, call `OpFetcher::request_ops(missing_parents, source)` Pending tree (sled) holds `PendingEntry {envelope_bytes, missing_parents, source, first_seen_micros, tried_peers}` ciborium-encoded under op-id keys. Restart-survives-state — the sled persistence carries pending entries across queue reinstantiation. Cascade promotion is a worklist (not recursion) so depth-N chains don't blow the stack; promoting one parent op can unblock any number of children, each of which may further unblock grandchildren. Multi-peer fallback (SPIKE §1.1's load-bearing fix for K2's source-bound fetch): a `tokio::spawn`'d watcher periodically scans pending entries whose `first_seen_micros` exceeded `fallback_timeout`; for each, picks an alternative arc-overlap peer via `PeerPicker` (skipping any URL in `tried_peers`), and re-issues `request_ops` against the new peer. Bounded by `max_retry_peers`. The watcher runs on the runtime handle passed to the queue at construction — Step 4 will hand it the same dedicated runtime `KitsuneRetreiverState` already uses, per the tokio-nesting risk register from SPIKE §2.6. Trait surface designed so Step 4 can wire K2's real modules without glue: `OpFetcher::request_ops` matches `kitsune2_api::Fetch::request_ops` verbatim; `PeerPicker::pick_arc_overlap_peer` is a thin abstraction over `PeerStore::get_by_overlapping_storage_arc`. `NotifyUp` is the bridge to AD4M's perspective-diff emit; Step 4 plugs the real impl. 12 unit tests pass (against mock fetcher/peer/notify): - happy path root op - one missing parent → pend + fetch → cascade promote on parent arrival - depth-3 missing chain → topo-ordered promotion when root arrives - signature failure drops the op entirely - fallback pass re-requests via alt peer - fallback bounded by max_retry_peers - pending tree persists across queue restart - duplicate-pending no double-fetch - duplicate-stored is no-op - outside-arc dropped - watcher start/stop lifecycle (idempotent) - watcher loop end-to-end (tokio runtime + tick → re-request) Total: 32 holograph unit tests pass (was 20), plus the prior 4 pdiff_parity integration tests and the 36 p-diff-sync HC-side tests. --- Cargo.lock | 1 + rust-executor/crates/holograph/Cargo.toml | 3 +- .../crates/holograph/src/integration_queue.rs | 568 +++++++++++++++ .../holograph/src/integration_queue/tests.rs | 649 ++++++++++++++++++ rust-executor/crates/holograph/src/lib.rs | 5 + 5 files changed, 1225 insertions(+), 1 deletion(-) create mode 100644 rust-executor/crates/holograph/src/integration_queue.rs create mode 100644 rust-executor/crates/holograph/src/integration_queue/tests.rs diff --git a/Cargo.lock b/Cargo.lock index 88295c6d2..5d7364070 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -9091,6 +9091,7 @@ dependencies = [ "tempfile", "thiserror 2.0.18", "tokio", + "tracing", ] [[package]] diff --git a/rust-executor/crates/holograph/Cargo.toml b/rust-executor/crates/holograph/Cargo.toml index cc6bf135b..6c1bd3e65 100644 --- a/rust-executor/crates/holograph/Cargo.toml +++ b/rust-executor/crates/holograph/Cargo.toml @@ -21,7 +21,8 @@ serde = { version = "1", features = ["derive"] } sha2 = "0.10" sled = "0.34" thiserror = "2" -tokio = { version = "1", features = ["rt", "rt-multi-thread", "sync", "macros"] } +tracing = "0.1" +tokio = { version = "1", features = ["rt", "rt-multi-thread", "sync", "macros", "time"] } # Step 2b — KitsuneRetreiver bridges to the p-diff-sync trait surface. # Per orchestrator's Option A (see .spike-status/blocker-step-1.5.md): diff --git a/rust-executor/crates/holograph/src/integration_queue.rs b/rust-executor/crates/holograph/src/integration_queue.rs new file mode 100644 index 000000000..c6df6521e --- /dev/null +++ b/rust-executor/crates/holograph/src/integration_queue.rs @@ -0,0 +1,568 @@ +//! `HolographIntegrationQueue` — sits above `KvOpStore` and is the +//!

New module `src/space.rs` ships: - `K2FetcherAdapter` — thin `OpFetcher` newtype over `DynFetch`. Signature matches `Fetch::request_ops` verbatim; no logic. - `K2PeerPickerAdapter` — wraps `DynPeerStore`, asks for arc-overlap agents on a 1-loc arc and skips any URL in the queue's `tried` set. - `ChannelNotifier` + `EmittedOp` — the queue's `NotifyUp` emits an `EmittedOp { op_id, created_at, envelope_bytes }` onto a `tokio::sync::mpsc::UnboundedSender` the Step-5 Language module will drain. - `HolographSpaceHandler` + `TelepresenceNotification` — K2 `SpaceHandler::recv_notify` passthrough into an mpsc; Step 5/6 owns the JS side. Returns `Ok(())` even when the sink receiver is gone so K2 doesn't tear down the peer connection on a local failure. - `LocalCommitTarget` trait (sealed via `K2DynSpaceTarget` for prod) separating the K2-side commit sink (inform_ops_stored + publish_ops) from the rest of the space — lets unit tests verify the commit-side logic without standing up the full K2 stack. - `HolographSpace::on_local_commit` — decodes envelope via the shared `EnvelopeDecoder`, queues it (parents always present for local commits so the queue takes the all-parents-present branch and stores+notifies straight away), then `inform_ops_stored` (gossip bookkeeping) + `publish_ops_to_peers` (eager hint to known peers so the user-perceived commit-to-propagate latency beats gossip cadence). - `HolographSpace::process_incoming_ops` — entry for K2 fetch/gossip inbound, delegates to the queue. - `K2OpStoreShim` — the `OpStore` impl K2 sees in its builder slot. `process_incoming_ops` routes through the integration queue when installed, falls back to direct `KvOpStore` storage otherwise (handles the brief construction window before the queue is built). All other 10 `OpStore` methods delegate to the underlying store unchanged (storage + Merkle bookkeeping stay where they are). `HolographIntegrationQueue::NotifyUp` extended to carry `created_at: Timestamp` alongside the op-id + bytes — needed because K2's `StoredOp` requires `created_at` for gossip and the value is derived from the envelope on the queue's decode side. The cascade promote path re-derives the timestamp from the pending envelope so promoted children get the correct `EmittedOp.created_at`. `Cargo.toml` adds `kitsune2 = "0.4..."` and `kitsune2_core = "0.4..."` on the same git rev workspace already uses for `kitsune2_api`. These are needed by the upcoming integration test against `MemTransport` + `MemBootstrap` (Step 4d). 11 new unit tests pass under `cargo test --release -p holograph --lib`: - on_local_commit stores/informs/publishes (verifies the three K2-side side-effects on a commit) - process_incoming_ops routes through queue (incoming path, no publish) - ChannelNotifier delivers EmittedOp tuple - SpaceHandler recv_notify forwards TelepresenceNotification - K2OpStoreShim routes through queue when installed - K2OpStoreShim falls through to store pre-install - K2OpStoreShim passthrough retrieve_ops (K2 fetch-response path) - K2OpStoreShim full passthrough surface (slice-hash, filter, count) - K2DynSpaceTarget impls LocalCommitTarget (compile-time bound) - K2 adapters impl queue traits (compile-time bound) Total: 43 lib tests + 4 pdiff_parity integration tests still green.

Test stack (`tests/space_two_node.rs`): - `kitsune2_core::default_test_builder()` baseline (mem_transport, mem_bootstrap, mem_peer_store, mem_peer_meta_store, mem_blocks, core_publish, core_fetch, core_gossip_stub, core_local_agent_store, core_kitsune, core_space, core_report) with our `K2OpStoreShim` swapped into the op-store slot. - `mem_bootstrap` shared `test_id` so Alice and Bob's peer stores discover each other; poll_freq overridden to 100ms. - `mem_transport` is process-global via OnceLock — both nodes auto-share without further wiring. - `TestLocalAgent` from `kitsune2_test_utils::agent` configured with `DhtArc::FULL` so each node participates in the gossip model for everything (v1 sharding-ready commitment 1, default arc). Test flow: 1. Build Alice and Bob, share `mem_bootstrap` test_id. 2. Trigger immediate mem-bootstrap poll + 800ms settle. 3. Alice `on_local_commit(root_envelope)` → her queue stores + emits + `inform_ops_stored` + `publish_ops_to_peers` (which fans out `Publish::publish_ops` to Bob). 4. Bob's K2 receives publish hint → triggers `Fetch::request_ops` → Alice's K2 serves via her shim → Bob's K2 calls Bob's shim's `process_incoming_ops` → Bob's queue → `ChannelNotifier` emit. 5. Test waits up to 30s on Bob's `emit_rx`; on a quiet laptop the round-trip completes in <1s. 6. Repeat with a child envelope whose parent = root. Bob's queue recognizes the parent is already present and takes the all-parents-present branch. Asserts: - Both nodes' `op_count == 2` after the chain. - Both ops' `EmittedOp` reach Bob's `ChannelNotifier`. - The K2-Bob-already-has-parent path works without requiring the multi-peer fallback (the parent arrived first via publish_ops). Additional fmt drift on `space.rs`, `space/tests.rs`, `integration_queue.rs` from `cargo fmt --all`. Adds `tracing-subscriber` and `kitsune2_test_utils` as dev-deps. Totals after Step 4 complete: 43 unit + 4 pdiff_parity + 1 two-node integration in holograph; 4 in perspective-diff-algorithm; 36 in perspective_diff_sync. 88 tests, all green. --- Cargo.lock | 64 +-- rust-executor/crates/holograph/Cargo.toml | 3 + .../crates/holograph/src/integration_queue.rs | 17 +- rust-executor/crates/holograph/src/space.rs | 39 +- .../crates/holograph/src/space/tests.rs | 23 +- .../crates/holograph/tests/space_two_node.rs | 372 ++++++++++++++++++ 6 files changed, 444 insertions(+), 74 deletions(-) create mode 100644 rust-executor/crates/holograph/tests/space_two_node.rs diff --git a/Cargo.lock b/Cargo.lock index c50d6bf09..14ca262cd 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -1414,7 +1414,7 @@ dependencies = [ "bitflags 2.9.4", "cexpr", "clang-sys", -

This matches the two-node pattern K2's own `core_space::test` uses and tightens the test focus on the bits we actually need to prove: - the publish_ops → fetch → process_incoming_ops round-trip through the real K2 transport - the queue's parent-presence check on the child envelope - both ends' `ChannelNotifier` mpsc receiving the EmittedOp Bootstrap discovery (mem_bootstrap test_id sharing, poll cadence, etc.) is K2's responsibility and is exercised by K2's own test suite — we were paying its variance in our smoke path for no signal. Captures the local URL via a `KitsuneHandler::new_listening_address` hook so we know which `Url` to publish into the other side's peer store. Builds an `AgentInfoSigned` per node using `AgentBuilder::default().with_url(url).build(TestLocalAgent)`. Total result: still 1 integration test passing, runs in <1s instead of 1.5–2s (no 800ms bootstrap settle). --- .../crates/holograph/tests/space_two_node.rs | 188 +++++++++--------- 1 file changed, 91 insertions(+), 97 deletions(-) diff --git a/rust-executor/crates/holograph/tests/space_two_node.rs b/rust-executor/crates/holograph/tests/space_two_node.rs index e56dfad97..e742e04cf 100644 --- a/rust-executor/crates/holograph/tests/space_two_node.rs +++ b/rust-executor/crates/holograph/tests/space_two_node.rs @@ -1,15 +1,21 @@ //!

Step 6 (next dispatch) wires the real `HolographSpace` instance behind these. ### Rust side (`rust-executor`) - New `src/holograph_wires.rs`: - `HolographHandle(u64)` — opaque per-neighborhood handle the JS side threads through every call. - `EmittedOpWire { op_id_b64, created_at_ms, envelope_b64 }` — the serializable JSON shape of `holograph::space::EmittedOp` returned by `nextEmitted`. - `HolographWireError` — `NotImplemented`, `UnknownHandle`, `InvalidEnvelope`, `Substrate(String)`. Step 5 only emits `NotImplemented`; Step 6 widens. - `HolographDelegate` trait — 8 methods documenting Step 6's contract against `HolographSpace`. - `NotImplementedHolographDelegate` — stub impl returning `NotImplemented` everywhere. 2 unit tests verify the stub and the wire-shape serde round-trip. - `src/js_core/host.js` — new section "Holograph (Spec section 7.8 -- OPTIONAL EXTENSION)". Wraps `globalThis.__holographDelegate__` with the same lazy-accessor pattern `__holochainDelegate__` already uses; throws a descriptive error if the runtime hasn't installed the delegate yet. - `src/lib.rs` — `pub mod holograph_wires;`. ### Host import surface (`ad4m-ldk`) - `js/src/host.d.ts` — adds the `holograph*` declarations + the `EmittedOpWire` interface. - `js/src/imports.ts` — re-exports the holograph wires + the `EmittedOpWire` type. ### Language module (`bootstrap-languages/holograph-link`) - `package.json` (`@coasys/holograph-link@0.1.0`), `tsconfig.json`, `esbuild.ts`, `README.md`, `.gitignore`. - `index.ts` — `defineLanguage()`-shaped Language exposing the standard AD4M LinkLanguage capabilities (`sync`, `commit`, `peers`, `telepresence`). Zero polling, zero `setInterval`, zero peer-revision walks: the subscriber loop is an `await holographNextEmitted(handle)` inside Rust (awaiting an mpsc receiver, not sleeping), and propagation is driven by the Step-3 queue + Step-4 publish/fetch glue. - `tests/smoke.test.ts` — Deno tests that load the bundled module with a data-URL host stub and verify (1) the bundle is non-empty, (2) all required flat exports are present, (3) init → commit → render → sync → currentRevision → teardown round-trips through the wires without errors. ### Bundle `pnpm run build` (`deno run --allow-all esbuild.ts`) produces `build/bundle.js` (~350 lines). The bundle imports `ad4m:host` externally, matching the executor's StringModuleLoader contract. ### Tests - `cargo test --features generate_snapshot holograph_wires` — 2 passed. - `cargo check -p ad4m-executor --features generate_snapshot --lib` — clean. - `cargo test --release -p holograph --lib -- --test-threads=1` — 43 passed (Step 4 baseline still green). - `deno test --allow-all tests/smoke.test.ts` — 8 passed. ### Step 5 vs Step 6 explicitly - Step 5 lands: JS module, wire-surface sketch, host imports, bundle, smoke tests. - Step 5 does NOT flip the neighborhood default (Step 6). - Step 5 does NOT install `__holographDelegate__` (Step 6 owns the isolate-install plumbing on the deno-core side). - Step 5 does NOT run the multi-conductor integration test (Step 7). Language address scheme: `hash("@coasys/holograph-link@")`; the canonical AD4M content-address hash function is what every other content-addressed Language uses, so the holograph-link Language picks its address from that namespace. --- ad4m-ldk/js/src/host.d.ts | 41 ++ ad4m-ldk/js/src/imports.ts | 17 + bootstrap-languages/holograph-link/.gitignore | 3 + bootstrap-languages/holograph-link/README.md | 60 +++ bootstrap-languages/holograph-link/esbuild.ts | 47 +++ bootstrap-languages/holograph-link/index.ts | 355 ++++++++++++++++++ .../holograph-link/package.json | 19 + .../holograph-link/tests/smoke.test.ts | 215 +++++++++++ .../holograph-link/tsconfig.json | 8 + deno.lock | 40 ++ pnpm-lock.yaml | 10 + rust-executor/src/holograph_wires.rs | 299 +++++++++++++++ rust-executor/src/js_core/host.js | 56 +++ rust-executor/src/lib.rs | 1 + 14 files changed, 1171 insertions(+) create mode 100644 bootstrap-languages/holograph-link/.gitignore create mode 100644 bootstrap-languages/holograph-link/README.md create mode 100644 bootstrap-languages/holograph-link/esbuild.ts create mode 100644 bootstrap-languages/holograph-link/index.ts create mode 100644 bootstrap-languages/holograph-link/package.json create mode 100644 bootstrap-languages/holograph-link/tests/smoke.test.ts create mode 100644 bootstrap-languages/holograph-link/tsconfig.json create mode 100644 rust-executor/src/holograph_wires.rs diff --git a/ad4m-ldk/js/src/host.d.ts b/ad4m-ldk/js/src/host.d.ts index d1451a01f..85ebe8e19 100644 --- a/ad4m-ldk/js/src/host.d.ts +++ b/ad4m-ldk/js/src/host.d.ts @@ -59,4 +59,45 @@ declare module "ad4m:host" { // language scope (e.g. test fixtures storing language bundles). export function readStorageFile(path: string): string; export function writeStorageFile(path: string, content: string): void; + + // Holograph (Spec section 7.8 -- OPTIONAL EXTENSION, new in v1 of the + // holograph-link Language).

Architecture: - `HolographRuntime` is process-global (lazy_static), owns a dedicated multi-thread tokio runtime (2 worker threads) and a `DashMap>`. - Each `NeighborhoodState` holds an `Arc` plus the `mpsc::UnboundedReceiver` half of `ChannelNotifier::new()`. - `create_neighborhood(space_id, storage_dir)` builds: * sled-backed `KvOpStore` under `/h/ops/`, * sled-backed `pending` tree under `/h/pending/`, * K2 `DynSpace` via `kitsune2_core::default_test_builder()` (mem transport + mem peer store + core fetch/publish + stub gossip) with our `K2OpStoreShim` substituted into the op-store slot, * `HolographSpace` wired via `HolographSpaceConfig::defaults` + Step-4 K2 adapters, * a sentinel `TestLocalAgent` joined to FULL arc (real AD4M-DID-bound agent identity is Step 7 territory). - `commit(handle, WireDiff)` encodes a CBOR `OpEnvelope` whose payload is JSON of the diff, drives `HolographSpace::on_local_commit`, returns the URL-safe base64 op-id. - `next_emitted(handle)` awaits the mpsc receiver inside the dedicated runtime — JS subscriber loops never spin. - `render`/`current_revision`/`latest_revision` return v1 placeholders; full Perspective render needs PR-B's algorithm-crate wiring. `HolographDelegate` trait + `NotImplementedHolographDelegate` stub removed — the deno op surface (Step 6c) calls `HolographRuntime` directly, no trait indirection. Wire surface evolved: - `holograph_envelope_decoder` re-exported from `holograph::space` so the executor can build envelopes that decode against the same Op-ID scheme `HolographSpace` already uses. - `EmittedOpWire` now carries a decoded `WireDiff` instead of raw base64 bytes — Step 6e's "envelope construction moves to Rust" landed in this commit too, so JS sees typed diff data on both ends. Cargo.toml additions: - `holograph` path dep + `kitsune2_api`/`kitsune2_core`/ `kitsune2_test_utils` git deps (same rev workspace already uses) + `sled` + `ciborium` + `dashmap` + `bytes`. Tests (`cargo test -p ad4m-executor --features generate_snapshot --lib holograph_wires -- --test-threads=1`): - `wire_diff_serde_round_trips` — JSON shape stable across ser/de. - `encode_decode_envelope_round_trip` — CBOR envelope wraps/unwraps a diff verbatim. - `invalid_envelope_decode_returns_error` — bad bytes yield typed err. - `unknown_handle_returns_error` — wires error on stale handle. - `create_commit_and_emit_round_trip` — load-bearing E2E: spin up a neighborhood, commit a diff, observe the emit on the receiver, verify op-id + diff round-trip through the substrate. - `render_returns_empty_links_v1` — placeholder shape stable. - `close_neighborhood_releases_handle` — cleanup correctness. - `revisions_default_to_none` — null pointers when no commit history. 8 tests pass.

Wires use `#[bigint] u64` for handles and `#[serde] WireDiff` for the typed perspective-diff payload. The deno_core::extension! macro is named `holograph_service`, matching the holochain naming. Revision-pointer ops use `#[string]` (empty string ↦ JS null) because `op2 #[serde] Option` isn't supported by the current macro. - New `rust-executor/src/js_core/holograph_service_extension.js`: Installs `globalThis.HOLOGRAPH_SERVICE` with thin async wrappers around the ops. The JS shim widens handles back from BigInt to Number and converts the empty-string sentinel back to null. Pure ASCII so the `ascii_str_include` macro check passes. - `rust-executor/src/js_core/mod.rs`: `pub mod holograph_service_extension;`. - `rust-executor/src/js_core/options.rs`: `holograph_service::init()` alongside `holochain_service::init()` in `language_worker_options::extensions`. - `rust-executor/src/js_core/language_bootstrap.js`: new `createHolographDelegate(languageAddress)` factory (mirroring `createHolochainDelegate`) that wraps the per-handle HOLOGRAPH_SERVICE in the spec-shaped delegate object. `initLanguage` installs the delegate on `globalThis.__holographDelegate__` alongside `__holochainDelegate__`, and exports `createHolographDelegate` as a global mirror of `createHolochainDelegate`. The Step-5 host.js's `holographDelegate()` accessor (which reads `__holographDelegate__`) now resolves cleanly: the runtime installs the delegate at language-init time, the Language module calls `holographCommit(handle, diff)` etc., the call routes through HOLOGRAPH_SERVICE -> op2 op -> HolographRuntime -> HolographSpace.

charset=UTF-8 Content-Transfer-Encoding: 8bit `rust-executor/src/neighbourhoods.rs` gains three small helpers implementing the SPIKE.md §2.2 Step 6 default switch: - `HOLOGRAPH_LINK_PACKAGE_ID = "@coasys/holograph-link@0.1.0"` -- the spike's canonical identity string for the holograph-link Language. - `holograph_link_default_address()` computes the canonical AD4M content-address (SHA-256 -> CIDv1 -> base58btc with the `Qm` prefix) so the address matches whether produced from Rust here or from the JS `hash()` host function. - `holograph_default_enabled()` reads `HOLOGRAPH_DEFAULT_NEIGHBORHOOD=1` from the process environment. - `resolve_link_language(Option) -> Result` is the load-bearing entry point: explicit address wins, empty/None with the flag set substitutes the holograph-link default, empty/None without the flag errors out cleanly (matches pre-Step-6 behavior for callers that don't opt in). API surface change: `PublishNeighbourhoodRequest.link_language` is now `Option` with `#[serde(default)]`, so callers may omit the field entirely or send empty-string and rely on the default switch. Existing callers that pass a populated address continue to work unchanged. `publish_neighbourhood` in `rust-executor/src/api/neighbourhoods_ws.rs` runs the input through `resolve_link_language` before forwarding to `neighbourhoods::neighbourhood_publish_from_perspective_with_context`. Resolution errors return `WsRpcError::bad_request` so a missing link_language without the env flag surfaces a clear 400 to the client rather than a confusing downstream failure. What this DOESN'T do (intentional, for Step 7): - `install_language` will fail when called against the synthetic holograph address because the holograph-link bundle isn't published to the language-language store. Step 7 wires bootstrap pre-install for the holograph-link bundle (or short-circuits install_language when the address matches the synthetic one). This commit gets the default-switch decision point landed; the install-side plumbing belongs to the multi-conductor work. Tests (`cargo test -p ad4m-executor --features generate_snapshot --lib neighbourhoods::tests -- --test-threads=1`): - `holograph_link_default_address_is_stable_qm` - `holograph_default_disabled_by_default` - `holograph_default_enabled_with_flag_one` - `holograph_default_disabled_with_flag_other_value` - `resolve_passes_through_explicit_address` - `resolve_substitutes_default_when_flag_set_and_empty_input` - `resolve_errors_when_flag_unset_and_empty_input` 7 pass. Existing `parse_publish_neighbourhood_request` test updated to the new `Option` shape; still passes. --- rust-executor/src/api/neighbourhoods_ws.rs | 4 +- rust-executor/src/api/tests/types_tests.rs | 2 +- rust-executor/src/api/types.rs | 10 +- rust-executor/src/neighbourhoods.rs | 157 +++++++++++++++++++++ 4 files changed, 169 insertions(+), 4 deletions(-) diff --git a/rust-executor/src/api/neighbourhoods_ws.rs b/rust-executor/src/api/neighbourhoods_ws.rs index 364ee9d3a..d2c3f3405 100644 --- a/rust-executor/src/api/neighbourhoods_ws.rs +++ b/rust-executor/src/api/neighbourhoods_ws.rs @@ -39,9 +39,11 @@ async fn publish_neighbourhood( .map_err(|e| WsRpcError::bad_request(format!("Invalid params: {}", e)))?; let agent_context = AgentContext::from_auth_token(ctx.auth_token.clone()); + let link_language = neighbourhoods::resolve_link_language(body.link_language) + .map_err(|e| WsRpcError::bad_request(e.to_string()))?; let url = neighbourhoods::neighbourhood_publish_from_perspective_with_context( &body.perspective_uuid, - body.link_language, + link_language, body.meta, &agent_context, ) diff --git a/rust-executor/src/api/tests/types_tests.rs b/rust-executor/src/api/tests/types_tests.rs index 8e21a7666..3d4b6ca5e 100644 --- a/rust-executor/src/api/tests/types_tests.rs +++ b/rust-executor/src/api/tests/types_tests.rs @@ -180,7 +180,7 @@ fn parse_publish_neighbourhood_request() { }); let req: PublishNeighbourhoodRequest = serde_json::from_value(json).unwrap(); assert_eq!(req.perspective_uuid, "test-uuid"); - assert_eq!(req.link_language, "Qm12345"); + assert_eq!(req.link_language.as_deref(), Some("Qm12345")); } #[test] diff --git a/rust-executor/src/api/types.rs b/rust-executor/src/api/types.rs index d2b6418b4..686e63e25 100644 --- a/rust-executor/src/api/types.rs +++ b/rust-executor/src/api/types.rs @@ -200,8 +200,14 @@ pub struct JoinNeighbourhoodRequest { pub struct PublishNeighbourhoodRequest { #[serde(alias = "perspectiveUUID")] pub perspective_uuid: String, - #[serde(alias = "linkLanguage")] - pub link_language: String, + /// Optional since Step 6 of the holograph spike: when omitted (or + /// empty) AND `HOLOGRAPH_DEFAULT_NEIGHBORHOOD=1`, the executor + /// substitutes the holograph-link Language address.

CBOR envelope wrap+unwrap (timestamp + signature + payload encoding) is owned by Rust now. This commit propagates the new shape to JS: - `ad4m-ldk/js/src/host.d.ts`: * Adds `WireDiff` interface alongside `EmittedOpWire`. * `holographCommit` signature is now `(handle, diff: WireDiff)` instead of `(handle, envelopeB64: string)`. * `EmittedOpWire` swaps `envelope_b64` for a typed `diff: WireDiff`. - `ad4m-ldk/js/src/imports.ts`: re-exports the new `WireDiff` type next to `EmittedOpWire`. - `bootstrap-languages/holograph-link/index.ts`: * Removes the Step-5 `encodeEnvelope`/`decodeEnvelope` JS helpers and the `envelopeToBase64`/`base64ToBytes` byte-juggling. * Replaces them with `toWireDiff`/`fromWireDiff` -- pure shape coercions between the Language-facing `PerspectiveDiff` class and the wire-facing `WireDiff` interface. * `commit` hands the typed diff straight across the wire; the Rust side runs `encode_envelope` and `HolographSpace::on_local_commit`. * Subscriber loop reads `next.diff` directly -- no envelope decode step. * Fixes the `asssertHandle` typo (extra `s`) to `assertHandle`. - `bootstrap-languages/holograph-link/tests/smoke.test.ts`: * `holographCommit` host stub takes a typed `diff` argument (not a base64 string). All 8 smoke tests still pass against the rebuilt `build/bundle.js`. Tests: - `pnpm run build` (deno esbuild) -- bundle rebuilds cleanly. - `deno test --allow-all tests/smoke.test.ts` -- 8/8 pass. --- ad4m-ldk/js/src/host.d.ts | 27 +++-- ad4m-ldk/js/src/imports.ts | 6 +- bootstrap-languages/holograph-link/index.ts | 102 +++++++----------- .../holograph-link/tests/smoke.test.ts | 4 +- 4 files changed, 59 insertions(+), 80 deletions(-) diff --git a/ad4m-ldk/js/src/host.d.ts b/ad4m-ldk/js/src/host.d.ts index 85ebe8e19..40d628c87 100644 --- a/ad4m-ldk/js/src/host.d.ts +++ b/ad4m-ldk/js/src/host.d.ts @@ -68,28 +68,33 @@ declare module "ad4m:host" { // if the runtime hasn't installed the delegate.

Re-generate the snapshot (`target/debug/generate_snapshot` from rust-executor/) before any ad4m-executor build that uses the snapshot. 2. print_holograph_address.rs: add an optional file-path arg. With no args it prints the Step 6d package-id-derived address (unchanged). With a file-path arg it prints the SHA-256/CIDv1/base58btc content address of that file's bytes — the same algorithm LanguageController::calculate_language_hash uses, so a bundle pre-installed at that address passes install_language's hash verification. 3. tests/holograph-link.test.ts: drop the package-id address. Shell out to print_holograph_address with the bundle path to derive the content hash, then pre-install + publishFromPerspective with that. Document that the env-default-switch (resolve_link_language) is unit-tested separately because routing it through the JS path needs the executor to itself derive the bundle's content hash at startup — a PR-B-shape config change.

Falls back to the package-id-derived address (with a warn-level log) when the env var is unset, so existing unit tests still see the legacy address. - resolve_link_language now calls holograph_link_resolved_address() for the substitution branch. The explicit-address and error-when-unset branches are unchanged. - holograph-link.test.ts: drop the explicit content-hash pin on the publish path. The test now sets HOLOGRAPH_LINK_BUNDLE_PATH + HOLOGRAPH_DEFAULT_NEIGHBORHOOD=1 in the conductor env and passes `undefined` as linkLanguage. The neighborhood assertion reads the correct NeighbourhoodExpression.data.linkLanguage path. Result: holograph-link.test.ts is 7/7 green end-to-end: publish-without-linkLanguage routes through the WS handler -> resolve_link_language -> install_language -> bundle loads -> PerspectiveDiff round-trips through the subscriber loop -> state survives a kill+respawn cycle.

Two modes: HOLOGRAPH_SBD_URL= set: transport -> Tx5TransportFactory (WebRTC via SBD signal server) bootstrap -> CoreBootstrapFactory (peer discovery via kitsune2-bootstrap-srv; URL from HOLOGRAPH_BOOTSTRAP_URL or derived from SBD URL by swapping scheme) gossip -> kitsune2_gossip::K2GossipFactory (replaces the CoreGossipStub which silently does nothing) HOLOGRAPH_SBD_PLAINTEXT=1 allows ws:// instead of wss:// (test harness runs bootstrap-srv on loopback). HOLOGRAPH_SBD_URL unset (default for in-process tests): unchanged from Step 6b -- default_test_builder, mem transport, mem bootstrap, stub gossip. Step 4d's space_two_node and Step 6f's two_node_via_wires both keep using this path and stay green. NeighborhoodState gains `dyn_space: kitsune2_api::DynSpace` so join_agent can return `dyn_space.current_url()` (the real reachable URL the transport publishes) instead of the "ws://holograph-local:0" placeholder. join_agent still falls back to the placeholder when current_url is None (mem path, or before Tx5 finishes the SBD handshake). ShimFactory + NoopSpaceHandler + NoopKitsuneHandler hoisted out of build_dyn_space_inner into module scope so both transport branches share them. The kitsune-handle Box::leak is still spike-acceptable per blocker-step-7.md; PR-B turns it into a real owned lifetime as part of the transport-config polish.

Boots one kitsune2-bootstrap-srv (which doubles as the SBD signal server) and two ad4m-executor conductors with HOLOGRAPH_SBD_URL + HOLOGRAPH_BOOTSTRAP_URL pointing at it, plus the env hooks from Step 8c so the default-switch substitutes the bundle's content address. Current state: 2/4 mocha cases green -- 1. Alice publishes a holograph-backed neighbourhood (publish-side setup + the Step 6d default switch via bundle content hash) 2. Bob joins via the neighbourhood URL (neighbourhood-language resolves the metadata, holograph-link is installed on Bob's side, the perspective is registered) Failing: cross-process op propagation (Alice's addLink does not reach Bob's subscriber within 60 s, and the same for the return direction). The setup is healthy -- both executors print "DynSpace built with Tx5 (sbd=...) + CoreBootstrap (server=...)" -- so the gap is somewhere between CoreBootstrap peer discovery and K2 publish/fetch firing across the SBD/WebRTC link. See .spike-status/blocker-step-9.md for the wake-10 debugging shopping list. The single-conductor test (tests/holograph-link.test.ts) and the substrate baseline (Step 4d / Step 6f + the holograph_wires lib tests) all stay green, so this commit does not regress any prior exit checks.

With two conductors both publishing AgentInfo for agent "test-1" to the bootstrap server, CoreBootstrap can't distinguish them and either dedupes or overwrites silently. Fix: when the Tx5 path is selected (HOLOGRAPH_SBD_URL set), spin up an Ed25519LocalAgent::default() instead -- random SigningKey on each call gives a process-unique 32-byte AgentId. 2. **Verifier paired with agent.** TestVerifier only accepts the literal TEST_SIG bytes; Ed25519LocalAgent produces real ed25519 signatures. AgentInfo verification across processes therefore silently fails with mismatched verifier/agent. Fix: pair the Ed25519LocalAgent swap with Ed25519Verifier on the Tx5 path. The in-process mem path (Step 4d / Step 6f) keeps the TestVerifier + TestLocalAgent pair so those tests don't churn. 3. **CoreBootstrap backoff.** Production default is 5000ms minimum (sensible). Cold-start convergence between two conductors on loopback at that interval pushed Test 3/4 past the 15s deadline. Lower to 500ms for the Tx5 path, overridable via HOLOGRAPH_BOOTSTRAP_BACKOFF_MIN_MS. Plus a robust agent-id log: AgentId Display invokes HoloHash-shaped decoding (32B only); switched to URL-safe base64 of the raw bytes + explicit byte length so the log doesn't panic for either the TestLocalAgent (13B) or Ed25519LocalAgent (32B) shape. Result: holograph-link-multi.test.ts is 4/4 then 5/5 green at the 15s test deadline -- Alice/Bob bidirectional sync AND late-join Charlie catches up via gossip. In-process tests unchanged (Step 4d space_two_node + Step 6f two_node_via_wires both still pass with mem transport + TestVerifier).

New "late-join Charlie sees historical diffs via gossip catch-up" test boots a third conductor AFTER Alice + Bob have exchanged their commits, joins via the same neighbourhood URL, and asserts that the two historical links surface via K2 gossip within 30s. Dedup before the set-equality assertion -- K2's gossip and publish paths can both deliver the same op to a fresh joiner, so the wire-level expectation is "the set of unique links contains {a->b, c->d}". holograph-link-multi.test.ts is now 5/5 green at the wake-10 boundary.

Iroh is QUIC-based direct P2P (no SBD signal relay required) and is K2's recommended default. Changes in rust-executor/src/holograph_wires.rs::build_dyn_space_inner: - transport: Tx5TransportFactory → IrohTransportFactory - Tx5TransportModConfig / Tx5TransportConfig → IrohTransportModConfig / IrohTransportConfig (matching field shapes: relay_url + relay_allow_plain_text instead of server_url + signal_allow_plain_text) - Env-var gate: HOLOGRAPH_SBD_URL → HOLOGRAPH_IROH_RELAY_URL - Plaintext flag: HOLOGRAPH_SBD_PLAINTEXT → HOLOGRAPH_IROH_PLAINTEXT - Fallback boot URL derivation: strip "/relay" off the configured iroh relay (kitsune2-bootstrap-srv serves both K2 bootstrap and the iroh relay endpoint on the same host:port). rust-executor/Cargo.toml: - kitsune2_transport_tx5 → kitsune2_transport_iroh dep at the same K2 rev (320a4d9). Iroh is already a workspace-level dep for the Holochain stack; no version drift. The in-process mem-transport path (no HOLOGRAPH_IROH_RELAY_URL) is unchanged from wake-10 — TestVerifier + TestLocalAgent + mem transport — so Step 4d's space_two_node and Step 6f's two_node_via_wires both stay green. Note: two-conductor JS test currently fails after this swap with peers=0 in publish_ops_to_peers — see blocker-step-11.md for the diagnosis (iroh net_report returns 400 on the bootstrap-srv relay probe, so `current_url()` stays None and CoreBootstrap can't publish AgentInfo). Single-conductor tests (test-simple, test-holograph-link) + all 113 substrate cargo tests stay green; the regression is isolated to cross-process op-flow via the new transport, not to the substrate or the JS isolate path.

Without this window, Alice's first commit fans out to peers=1 (herself only) and the diff never reaches Bob, even though test 4 (Alice receives Bob's later commit) and test 5 (Charlie historical catch-up via gossip) both pass naturally. The diagnostic logs from Step 10a made the asymmetry obvious -- Bob discovered Alice within 3s but Alice discovered Bob after ~20s because Bob's URL was published a tick later. Pad the first cross-process commit with a 15s settle so the bootstrap publish is guaranteed to have reached both sides before publish_ops_to_peers fans out. The natural fix is on the consumer side (a retry or wait inside HolographSpace::on_local_commit when peers=0), but that's a substrate behaviour change deserving its own PR. The test-side settle is the spike-acceptable workaround per the wake-12 dispatch. Combined with the matching bootstrap-srv (`kitsune2-bootstrap-srv 0.4.0-dev.5`, installed from the same K2 rev our workspace pins), this brings holograph-link-multi.test.ts back to 5/5 green on the iroh transport. The matched bootstrap-srv install closes the wake-11 blocker's iroh-relay version skew root cause.

The smoke test reads `build/bundle.js`, which doesn't exist if `build` hasn't run. Add a `pretest` script that runs the same esbuild command as `build`, so `pnpm test` self-builds the bundle when needed. This matches the pnpm/npm convention -- pretest runs automatically before test -- without requiring any change to the CircleCI job or the turbo task graph. Locally and in CI both `pnpm test` and `pnpm build && pnpm test` are now idempotent. Verified locally: removed `build/bundle.js`, ran `pnpm test` in `bootstrap-languages/holograph-link`, all 8 deno smoke tests pass.

The narrow Step 1.5 (topo-sort only) is becoming a wide extraction of the entire DAG algorithm. This first move tackles `link_adapter::chunked_diffs` — the splitter that batches large perspective-diffs into bounded chunks before they land in the DHT. Design pattern (now the precedent for the remaining 8 file moves): - algorithm crate defines mirror types for the integrity-zome wire shapes: `LinkExpression`, `PerspectiveDiff`, `Triple`, `ExpressionProof`. Byte-for-byte compatible serde shape but no HDI / SerializedBytes / `app_entry!` decoration. Lives in `crates/perspective-diff-algorithm/src/diff_types.rs`. - algorithm crate hosts the pure splitter/aggregator (`new`, `add_additions`, `add_removals`, `into_aggregated_diff`, plus the unit tests that don't need MockPerspectiveGraph) in `crates/perspective-diff-algorithm/src/chunked_diffs.rs`. - p-diff-sync's `link_adapter::chunked_diffs` becomes a thin HDK adapter: it keeps the IO methods (`into_entries`, `from_entries`, `load_diff_from_entry`) and the integrity-zome conversions, but delegates the data manipulation to `AlgoChunkedDiffs`. The integrity↔algorithm conversions are field-by-field (cheap; no serde round-trip). The public API of `ChunkedDiffs` stays the same for callers (`commit.rs`, `pull.rs`), so no other p-diff-sync files needed changes. The `.chunks` field is now a method (`chunks()`) returning the integrity-zome shape; tests that read it for `format!("{:?}")` debug-equality were updated accordingly. Tests: - 3 pure unit tests moved from p-diff-sync chunked_diffs::tests to the algorithm crate (can_chunk, can_aggregate, can_chunk_big_diffs). All green via `cargo test --release -p perspective-diff-algorithm`. - 4 HDK IO tests stay in p-diff-sync (can_write_and_read_entries, test_nested_chunked_entries_are_handled, test_from_entries_with_mixed_chunked_and_inline, test_loading_empty_chunked_entry_returns_empty_diff). All green via `cargo test -p perspective_diff_sync --lib`. - algorithm crate: 7 tests (was 4: topo_sort; +3: chunked_diffs). - p-diff-sync zome: 33 tests (was 36; -3 moved to algorithm). - holograph crate: still compiles. - ad4m-executor: still compiles. Remaining file moves (workspace.rs, snapshots.rs, revisions.rs, render.rs, pull.rs, commit.rs, retriever.rs + retriever/mock.rs, test_graphs.rs, tests.rs) follow the same pattern but each adds new mirror types + new abstractions on the retriever trait — see `.spike-status/step-13-status.md` for the remaining-work map.

Adds the algorithm-crate Workspace as a working parallel implementation alongside p-diff-sync's existing HDK-coupled one; phase 2 (wake-15) updates p-diff-sync's commit/pull/render to delegate to this and removes the duplicate. What's new in the algorithm crate: - `diff_types.rs` extends with three new mirror types: * `Hash(pub [u8; 39])` — wraps the 39-byte raw form of `HoloHash`. Custom `Serialize`/ `Deserialize` via a 39-byte serde_bytes-compatible visitor so bincode/messagepack round-trips match HoloHash's own shape. `from_raw_36(&[u8; 36])` is the bridge for the `NULL_NODE` / test-generated payloads. * `PerspectiveDiffEntryReference` — same fields as the integrity zome's, but parents/diff_chunks use the new `Hash` mirror. Includes `HasDiffParents` impl so the existing `topo_sort_diff_references` works on it directly. * `Snapshot { diff_chunks: Vec, included_diffs: Vec }`. Plus the `null_node()` free fn — equivalent of the integrity zome's `ActionHash::from_raw_36(vec![0xdb; 36])` sentinel. - `errors.rs` introduces `AlgoError` / `AlgoResult` — the algorithm crate's compact, HDK-free error type. p-diff-sync's `SocialContextError::from(AlgoError)` would handle the HDK-boundary conversion (wake-15 hookup). - `retriever.rs` defines the `WorkspaceRetriever` trait — the minimum surface the in-crate `Workspace` needs: `fn get_p_diff_reference(hash: &Hash) -> AlgoResult;` `fn get_snapshot_by_target(target_hash: &Hash) -> AlgoResult>;` p-diff-sync's `PerspectiveDiffRetreiver` keeps the rest (current_/ latest_revision, update_*, create_entry, etc.); wake-15 adds the HDK impl of `WorkspaceRetriever` on `HolochainRetreiver`. - `workspace.rs` ports the full Workspace struct + every algorithm method from p-diff-sync's `link_adapter::workspace.rs`: * `Workspace::new()`, `collect_only_from_latest`, `handle_parents`, `sort_graph`, `build_diffs`, `terminate_with_null_node`, `collect_until_common_ancestor`, `build_graph`, `get_p_diff_reference`, `add_node`, `get_node_index`, `find_common_ancestor`, `squashed_diff`, `all_ancestors`. * Generic over `R: WorkspaceRetriever` everywhere the retriever is needed; pure methods stay un-parameterized. * Uses `null_node()` everywhere `NULL_NODE()` was used on the HDK side. * Replaces `SocialContextError`/`Result` with `AlgoError`/Result` and `itertools::unique()` with a small in-fn `seen-set` filter (algorithm crate stays light on deps). * Removes the `print_graph_debug` and HDK `debug!` calls — the algorithm crate doesn't depend on a logger. - Tests: 5 of the 8 original `workspace::tests` ported to the algorithm crate, using a small in-crate `MockRetriever` driven by a minimal graphviz `digraph { ... }` parser (`MockGraph::from_dot`). The remaining 3 tests (`complex_merge`, `complex_merge_implicit_zero`, `real_world_graph`) stay in p-diff-sync for now since they still pass against the unchanged HDK Workspace; wake-15 will port them when p-diff-sync's Workspace becomes the algorithm-crate's. Test green-bar after Phase 1: - `perspective-diff-algorithm` unit: 12 (was 7; +5 ported workspace tests) - `perspective_diff_sync` lib unit: 33 (unchanged; original Workspace + chunked_diffs from Step 13b-A still in p-diff-sync) - `holograph` crate: still compiles - `ad4m-executor`: still compiles Phase 2 (wake-15) will: 1. Make p-diff-sync's `Workspace` a re-export of the algorithm crate's 2. Impl `WorkspaceRetriever` for `HolochainRetreiver` and `MockPerspectiveGraph` (bridge integrity types ↔ algorithm mirrors) 3. Update commit.rs / pull.rs / render.rs to handle the new mirror types (small conversion shims at the boundary) 4.

charset=UTF-8 Content-Transfer-Encoding: 8bit Wake-15 track 1: the substrate-agnostic `perspective_diff_algorithm::Workspace` is now the only Workspace. p-diff-sync's `link_adapter/workspace.rs` shrinks to a thin shim re-exporting it plus a legacy `NULL_NODE()` helper. Callers (`pull`, `render`, the HDK-boundary tests, and the holograph parity tests) convert `HoloHash` ↔ `algo::Hash` at the workspace boundary via the new conversions module. - Add `impl algo::WorkspaceRetriever` for `HolochainRetreiver`, `MockPerspectiveGraph`, and `KitsuneRetreiver` (holograph crate). Mock / Kitsune return Ok(None) for snapshot lookups (no snapshot links on those paths in this spike). - Add `SocialContextError::Algo(String)` and `From` so `?` propagates cleanly through pull/render; the algorithm's `NoCommonAncestorFound` variant maps to the existing `SocialContextError::NoCommonAncestorFound` so any pattern matches still fire. - Port 3 workspace tests (`complex_merge`, `complex_merge_implicit_zero`, `real_world_graph`) to the algorithm crate, taking its workspace coverage from 5 → 8 tests. p-diff-sync's `link_adapter::tests` (3 HDK-boundary tests) retained with `hash_to_algo` at the call. - `conversions` module promoted from `pub(crate)` to `pub` so the holograph crate (which now depends on perspective-diff-algorithm directly) can use it. Tests green: perspective-diff-algorithm (15/15), perspective_diff_sync lib (24/24), holograph (48/48 — 43 lib + 4 pdiff_parity + 1 two_node), ad4m-executor (cargo check clean). `cargo fmt --all --check` clean.

Walk parents from `latest` (DFS with sibling-branch deferral). 2. At each node, aggregate inline / chunked diffs. 3. At boundary nodes (`diffs_since_snapshot == 0`) with a `Snapshot` link, fold the prior snapshot's diffs into the aggregator and mark its `included_diffs` as seen. 4. Chunk the aggregated diff, write each chunk via `create_diff_entry`, return the assembled `Snapshot` (caller persists it). Includes 2 in-crate tests: - `collects_inline_chain_into_chunked_snapshot` — 4-node linear chain → 4 link expressions across the new snapshot's chunks. - `folds_previous_snapshot_into_new_one` — prior snapshot's chunks + included_diffs are carried into the new snapshot, plus the unsnapshotted tail. p-diff-sync's `link_adapter::snapshots` becomes a thin shim in the next commit. 17/17 algorithm-crate tests green.

charset=UTF-8 Content-Transfer-Encoding: 8bit Replace `bootstrap-languages/.../link_adapter/snapshots.rs` (~250 LOC of DAG walk + chunk aggregation) with a ~15-line HDK adapter that delegates to `perspective_diff_algorithm::generate_snapshot`. Pattern matches the 13b-C Workspace consolidation. - Impl `algo::SnapshotRetriever` on all three substrates: HolochainRetreiver, MockPerspectiveGraph, KitsuneRetreiver. Each reuses the existing `PerspectiveDiffRetreiver::create_entry` to persist chunk-diff entries and returns the resulting hash in algo form. - HDK shim reads `*CHUNK_SIZE` from the lazy_static config and converts the integrity-zome `Snapshot` ↔ `algo::Snapshot` at the boundary via the conversions module (drops the now-unused `#[allow(dead_code)]` on `snapshot_from_algo`). Tests green across all three crates + ad4m-executor: - perspective-diff-algorithm: 17 / 17 (15 prior + 2 new snapshot tests) - perspective_diff_sync lib: 24 / 24 - holograph: 48 / 48 (43 lib + 4 pdiff_parity + 1 two_node) - ad4m-executor: cargo check clean `cargo fmt --all --check` clean.

Adds the `HashReference` and `LocalHashReference` mirror types in `algo::diff_types` and a sibling `RevisionsRetriever` trait that all three substrates (Holochain, Mock, Kitsune) implement. - algo `diff_types`: new mirror types `HashReference` / `LocalHashReference` (both `{ hash: algo::Hash, timestamp: chrono::DateTime }`). Adds chrono as a direct algo-crate dep. - algo `retriever`: new `RevisionsRetriever: WorkspaceRetriever` sibling trait with `current_revision`, `latest_revision`, `update_current_revision`. - algo `revisions`: thin wrappers `current_revision::()`, `latest_revision::()`, `update_current_revision::(hash, ts)`. - p-diff-sync `link_adapter::revisions`: now a 25-line HDK shim that preserves the legacy integrity-zome return type (`Option`) so pull/render/commit callers don't yet need mirror types. - p-diff-sync `link_adapter::conversions`: + `hash_ref_to_algo` / `hash_ref_from_algo` and `local_hash_ref_to_algo` / `local_hash_ref_from_algo` (field-by-field copies). - pull / render / commit / handle_broadcast / broadcast_current: add the `algo::RevisionsRetriever` trait bound. Same call surface, just a wider bound on the generic. - Holochain / Mock / Kitsune retrievers: impl `RevisionsRetriever` forwarding to their existing `PerspectiveDiffRetreiver` revision methods via the new mirror-type conversions.
