SY-4471: Arc flow variables in the C++ runtime (#2636)

2026-07-27

Merge remote-tracking branch 'origin/rc' into sy-4471-arc-cpp-flow-variables

SY-4232: Standardize service folder structures in the backend (#2606)

2026-07-25

SY-4471: Declare the combined channel direction A channel alias is readable and writable, so the analyzer builds its direction by combining the read and write bits. That combination was never a declared variant, and the generated protobuf translator rejects undeclared values, so configuring an arc task on a driver-backed rack failed whenever the program aliased a channel. The variant is now declared, leaving the bitmask predicates and every existing value unchanged.

2026-07-22

SY-4293: Accept variables and channel aliases as node input values - Add the var_ref type kind: literal (:= / $=) variables bind to their variable node and read live at fire time; never-written variables inline their initial - Reject reactive variables for value and channel params; channel aliases resolve to their source channel, rebound aliases read the register's live key - Convert ranges, status, and control.set_authority to field-less natives reading inputs through node.State; back zyn ObjectZ.Validate with Dump - Add the NodeSpec/VarInput test fixture with mirrored const/var/alias coverage

SY-4293: Accept literal variables as flow brace input values

2026-07-21

SY-4293: Replace scope resetNodes with variable node members Variable registers and derefs are now members of their declaring scope instead of always-live root nodes, so the existing member-reset machinery re-seeds them on scope activation and the resetNodes field disappears from the IR. Sequential scopes carry their variable nodes in strata, which run every pass alongside the active step; stateful registers already no-op their Reset, so $= persistence is unchanged. Rewrites the scheduler reset specs against the new mechanism.

SY-4488: Assign task config hashes in core Core hashes a task's config on every write and stores it in the new config_hash field. The field is server-assigned and ignored on writes from clients, and rides along on sy_task_set, which strips only config and status. Config is a decoded map at every hop and never survives as bytes, so a client-computed hash would need an agreed canonicalization implemented in Go, C++, TypeScript, and Python. Hashing once, where the config is written, makes drift a comparison of two server-assigned values instead. The UUID re-key migration backfills config_hash in the same pass.

SY-4293: Variable read, self-write, and re-seed semantics Reassigned-variable expression reads compile via lifted Internal input params fed by variable-node edges. Variable reads fire only on values they have not consumed, surviving scope re-entry; self-write feeders re-arm only on scope entry, so increments run once per activation. Scheduler.Next runs bounded settle passes when a change lands on a node that already ran, so variable writes propagate within the tick. `:=` variables re-seed on declaring-scope entry via ir.Scope.resetNodes (`$=` persists). Stage bodies lower against the stage's own scope, fixing stage-scoped flow sinks. Variable output is deep-copied so feeder buffer reuse cannot mutate held values.

SY-4346: Correct Node Key Docs Across Schemas The node.oracle Key doc claimed 0 is the reserved free key; the free key is 4095 (MaxUint12, aspen node.KeyFree). Drop the redundant qualifiers in the channel and rack key docs: 'cluster node key' and 'core node key' are now 'node key', and channel leaseholder docs say 'the node' rather than 'the cluster node'.

Merge remote-tracking branch 'origin/rc' into sy-4293-arc-scoped-variables

SY-4293: Remove VarKind, derive variable classification from type Delete the VarKind enum across all languages and the IR. A value variable's flavor now derives from its symbol kind and data type: writable channel is a read/write alias, read-only channel is reactive, non-channel is a literal. Add IsChannelReadWrite, IsReactive, and IsLiteral predicates on Symbol; replace the IR VarKind field with IsLiteral and BacksInternalChannel bools.

SY-4488: Task identity uint64 to UUID with rack as row field Task keys become client-mintable UUIDs; rack moves from key bits to a plain row field (0 = draft). sy_task_set carries task metadata JSON without config or status; sy_task_delete carries UUID bytes. Identity migration re-keys existing rows, rewrites ontology resources/relationships and statuses, and stages a uint64-to-UUID map consumed by the panel layout migration. Rack is no longer derivable from a task key anywhere; drivers filter on the rack field and clients thread rack through create/retrieve flows. Rack moves are now a field write with the same key instead of delete-and-recreate.

SY-4330: Move Group Service, Ontology, and Search Index Out of the Distribution Layer (#2600)

SY-4331: Move most channel functionality to service layer (#2499) Moves most channel functionality from the distribution layer up to the service layer, tightening the 5-layer boundary so the distribution layer holds only what telemetry routing and storage need.

SY-4293: Rename variable types (mechanical) Constant -> Literal Reactive -> ChannelRead ChannelAlias -> ChannelReadWrite

2026-07-12

Convert panel tabs to a resource/view content union Tab content is now a discriminated union: a resource tab displays a backing core document via an ontology ID, while a view tab is an inline, self-describing view with a Console-owned type and opaque args. The empty variant is gone; a freshly created tab is a selector view. New SetTabResource/SetTabView actions swap a tab's content in place without changing its identity or position, and InsertTab is idempotent on resources (a resource may back at most one tab per panel). Oracle gains @create support on unions, synthesizing a TS-only NewTab z.input projection that mints tab keys at parse time. The pluto Panel.Mosaic is rebuilt as store-driven Node/Leaf/Split components selecting per-node slices, with Panel/Tab scopes delivering keys to render seams and an ambient select context resolving per-leaf selection and focus. Client tree helpers are renamed to the path-key vocabulary (ROOT_NODE_KEY, childNodeKey).

SY-4418: Track additional files in copyright checks (#2564) Audits every file type tracked in git for copyright-header enforcement and brings the missing ones under the check, then reconciles the copyright tooling with pnpm format (Prettier) so the two never disagree.

2026-07-05

SY-4418: Track proto, xml, pyi, bazel, ps1, cmd, g4, glsl, bzl, c in copyright checks Extends check_copyrights.sh / update_copyrights.sh to cover file types that were tracked in git but not in the copyright allow-list: proto, g4, glsl, c (// style), bazel, bzl, ps1 (# style), pyi (# two-space, like py), cmd (rem style), and xml (<!-- --> style). Generalizes the shebang handling into a leading-line regex so cmd's `@echo off` and glsl's `#version` directives are preserved above the header. Refines the duplicate-header heuristic to count only genuine header lines, not data lines embedding the notice (the JetBrains copyright-profile XML). Narrows .copyrightignore from all of vendor/** to just the five vendored submodules, so our own files under vendor/ (Bazel glue, the SOEM macOS port, build scripts) are now checked and headered.

SY-4293: Replace is_var with explicit variable kinds The single is_var flag on IR nodes conflated reflect-current and stream read semantics, which made a seeded variable read inside a sequence return its seed instead of the latest write. Replace it with an explicit VarKind (channel alias, reactive, const) inferred once from a variable's declaration RHS and carried through to the runtime. - schema: is_var bool becomes a var_kind VarKind enum (Go/TS/Py/proto regen) - analyzer: infer the kind from the RHS, record it on the symbol - lowering: tag on/write nodes with their VarKind - runtime: const variables reflect their current value; aliases, reactive variables, and plain channels stream

SY-4331: rename channels via map[Key]string through transport and cesium

SY-4445: Rename Arc graph configs wire field to inputs

SY-4293: Tag reactive value-variable nodes with is_var in the IR Whether a reactive node reads or writes a value variable is a compile-time fact, but the runtime rediscovered it through a channel-keyed varChannels set. Add an is_var flag to the IR Node so the compiler records it once and each on/write node self-describes.

SY-4293: Unify top-level declarations with scoped variables - Route top-level := / $= through the scoped-variable analyzer path; delete the constant package and KindGlobalConstant. Variables supersede constants, so top-level names are source-order and support channel aliasing. - Back value variables with channels: reads sample the current value on activation, writes are observed, declarations seed the channel. - Carry startup seeds declaratively in the IR (var_seeds), pre-filled at ProgramState construction instead of a seed node's Create side effect. - $= seeds like :=.

SY-4432: Refactor distribution proxy And transport (#2531)

2026-06-25

Arc Reactive Value Variables Back reactive value variables with internal "variable channels" so they can be written and read across stages within a sequence. - A value variable written via a flow sink (expr -> counter) is backed by a program-local channel: reads lower to `on` nodes, writes to `write` nodes on the variable's key. Instantiation (counter := 0) is not a reactive write. - IR carries `var_channels`; these keys are kept program-local (looped from writes back into reads, excluded from Core read/write retrieval) rather than synced to the cluster. - Reject `=` assignment in a reactive scope with a hint to use a flow. - Fix same-unit classification for identifier reads so module-level variables are not misclassified as inherited variable channels.

Document distribution channel transport and proxy/transport public APIs Add doc comments to the distribution channel Transport interface, its operation transports, and the create/delete/rename request payloads (and their fields), and to the channel proto services/messages in services.proto (regenerated). Document the remaining exported methods across the distribution transport gRPC and mock implementations so every public identifier carries a comment.

Add distribution proxy/transport tests, docs, and rename channel proto services Bring over the new proxy and distribution transport test suites, document the public transport types/methods, and fix bugs surfaced by the tests: the gRPC framer deleter client had a nil Exec, the framer deleter server was never bound, server-side (and deleter) middleware was never wired into Use, and channel Use skipped rename. Mark internal node-to-node servers as Internal for richer error encoding. Rename the distribution channel gRPC services ChannelCreateService/ ChannelDeleteService/ChannelRenameService to CreateService/DeleteService/ RenameService and regenerate the protobuf stubs.

SY-3961: Add a single-round-trip ranges set_end API Move SetEnd from the ranger Service to the Writer (mirroring Rename) and expose it as a dedicated set_end endpoint across the gRPC and HTTP transports. The C++ client gains a set_end method and the Arc driver's dispatch_end now closes a range in one network request instead of a retrieve followed by a create. SetEnd tests move into writer_test.go.

SY-4392: Make CRDT counter uint32 and emit py/cpp/pb crdt outputs The replicated-text character counter was uint64, which serializes to a JSON string in TypeScript (bigint) and fails to decode into a Go uint64 field on the collaborative-edit dispatch path. A per-replica, per-session character counter never approaches 2^32, so narrow it to uint32: it now serializes as a JSON number and round-trips cleanly across the wire. Also generate the crdt types for Python, C++, and protobuf (adding the @py output to spatial, which crdt imports, plus hand-written __init__.py for the new x.crdt and x.spatial packages), and carry over the Fugue snapshot/load core and its non-interleaving + round-trip property tests.
