Maps The Graph's manifest, schema, and graph-ts mappings API (specVersion 0.0.4-1.3.0, apiVersion 0.0.5-0.0.9) onto HyperIndex's current surface, and sketches the shim design: AsyncLocalStorage entity-write scoping, a register pass for dataSource.create, and a sync-over-async bridge for store.get and eth_calls.

…re errors The worker/codemod bridge is dropped in favor of try-sync reads against the in-memory state (hasInMemory/getUnsafeInMemory already exist per load group), throwing an envio-owned suspend error on miss while the load is scheduled, then rerunning the handler once it resolves. Preload batches the warmup so the execute pass replays zero times in the common case. Unsupported subgraph features now fail with a uniform loud error instead of no-ops: callHandlers, block filter:call, graft, nonFatalErrors, subgraph composition, and event.receipt.logs at runtime.

…, implementation plan Interfaces and timeseries/aggregations now fail with the uniform unsupported-feature error. Suspending marks the per-event context as aborted so a caught suspend error stops the handler on its next context access. The doc is restructured around a short how-it-works summary, condensed tables, and a phased implementation plan (core sync API, CLI subgraph mode, graph-ts shim, e2e scenario).

…ime home, ens, replay cap isResolved and the abort flag merge into one contextStatus (Active | Aborted(exn) | Resolved) shared by reference with entity sub-proxies. The sync/suspend API stays internal-only for the subgraph runtime, which ships inside the envio package as an envio/subgraph subpath so versions stay lock-step. ens.nameByHash becomes a best-effort cached effect returning null on miss. Replay termination is a progress check plus a fixed high round cap, not configurable.

… config, drop replay cap Block handlers expose only block.number; other ethereum.Block fields, and event.transactionLogIndex, throw the unsupported-feature error on access. The parsed manifest passes through the resolved public config JSON under a subgraph field instead of a normalized copy in .envio/. The replay termination guard is dropped for the first iteration. Int8->BigInt rationale noted (64-bit vs 32-bit Int). Testing adds an Envio Subgraph tool to the open-indexer-benchmark repo running its Subgraph case on HyperIndex.

…dation tests Unknown manifest fields/kinds/versions, schema directives/arguments/types, and runtime graph-ts API accesses are refused with an 'unknown' error (distinct from 'unsupported') that still points at updating envio or opening an issue. SubgraphValidation_test.res in envio-tests, patterned on UserApiValidation_test.res, asserts exact messages for every unsupported and unknown case.

…oxy, throwing getters Namespace objects get full Proxies (unenumerable future APIs, cold path); hot classes get a Proxy at the bottom of the prototype chain so known members never pay trap cost while unknown names still throw; known-but- refused fields use plain throwing getters with the unsupported error. Traps allowlist symbols and thenable/inspect names, and ESM link errors for missing named imports are rewrapped into the unknown-error template.

…ction Verified against graph-tooling's codegen: generated entity classes, contract bindings, event and template classes are implemented purely in terms of graph-ts APIs (Entity/Value/TypedMap/store, ethereum.SmartContract, DataSource.create). So generated/ needs no shim - the real graph codegen output executes on top of the graph-ts shim, the editor keeps seeing the real package types, and conformance is tested via golden generated/ fixtures across graph-cli versions plus a type-level satisfies check against real graph-ts declarations.

ENVIO_API_TOKEN via env or .env, ENVIO_RPC_URL shared by sync fallback and contract-call effects (comma-separated fallback list), and an optional envio.yaml overlay for the full envio surface the manifest can't express.

Value is url | JSON object | JSON array of either, parsed with the same schema and deny-unknown rules as config.yaml's rpc field, injected verbatim into the generated chain config (bare URLs default to fallback) and reused in order by the shim's call effects.

The subgraph runtime needs graph-ts' synchronous host ops on top of envio's async ones. This lands the core half of that bridge: - `contextStatus` (Active | Aborted(exn) | Resolved) replaces `isResolved`, held by reference so the entity sub-proxies share the handler context's lifecycle — and their traps and op closures now enforce it. - `getSync` / `getWhereSync` / `getInBlockSync` / `effectSync` read the in-memory state and, on a miss, schedule the async op and suspend. - `runSync` awaits what a round scheduled and replays the body from the top, capped at 10k rounds. All internal: not in index.d.ts, reserved for the subgraph runtime. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_016tA2D3BrcAJS4nME7noXh4
Manifest parsing walks the YAML by hand instead of deriving serde structs: deny-unknown has to report every unknown key with its path, and a project should see all of its problems in one run rather than one per attempt. The schema translator owns strictness for the same reason — envio's parser ignores unrecognised directives and doesn't require @entity.

The graph-ts shim and the runtime that drives it live inside the envio package with no subpath export: nothing outside imports them, and HandlerLoader activates them when the resolved config carries a translated manifest. Mappings resolve @graphprotocol/graph-ts to the shim at runtime only, so types keep resolving to the real package. Each manifest handler becomes an onEvent/onBlock wrapper running the mapping inside runSync, with dataSource.create captured by a contractRegister pass that reruns the same mapping in register mode.

parse_from_project_files is the one door dev, start and codegen all go through, so keying subgraph mode off a subgraph.yaml with no config.yaml beside it is enough to make all three work inside an unmodified project. A mapping importing the project's generated/ is the only thing that makes graph codegen necessary, and the failed import is exactly where that shows up — so the runtime builds it there, with the project's own graph-cli. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_016tA2D3BrcAJS4nME7noXh4
Factory + template + eth_call + block handler, indexed straight off subgraph.yaml with no envio config anywhere in the project. Running it surfaced a gap: the register pass has no effect caller, so a mapping that calls a contract crashed instead of reporting. An effect reached before any create() could have decided which address to register, so it is refused with the §7 error; once registration has happened the rest of the mapping only feeds writes that are no-ops there, so it is skipped.

The scenario's mappings now import the project's generated/ the way a real subgraph's do, and that output is real `graph codegen` from a pinned graph-cli, checked in so the mappings run against exactly those bytes. Running it found three things the hand-written mappings never reached: - `new ethereum.CallResult()` is how a generated binding signals a revert, so the constructor has to default to reverted. - Generated code asserts on `Value.displayKind()`, which was missing. - `changetype<Pair | null>(store.get(...))` erases its type argument, so a loaded entity reaches the mapping without the generated prototype that carries `pair.token0`. The entity prototype tail now falls through to the stored field, typed by the Value kind — which is what the generated getter would have returned. A name the entity doesn't hold is still refused.

A manifest names an event by a signature with no parameter names. Envio reads the parameters out of the ABI itself, so a unique name is all it needs — but an overloaded name isn't unique, and envio's routing rejects two events sharing one. Those get the spelled-out human-readable signature and a suffixed name, which the runtime then registers under.

envio hands a block handler only the block number. Every handler invocation in a batch asks for its timestamp within the same microtask, so the requests are collected and answered by a single HyperSync range query instead of a round trip per block — which is also what keeps a block handler from needing an RPC endpoint at all. RPC covers whatever HyperSync couldn't answer. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_016tA2D3BrcAJS4nME7noXh4
Running a third-party subgraph project surfaced both of these. A subgraph project's package.json carries no `type`, so tsx loads its mappings and its generated/ as CommonJS — and reaching the shim, a real ES module, through require() is what Node refuses inside a cycle. The resolve hook now declares files under the project root as modules, which is what they are. Codegen also has to run before the first mapping import rather than in response to it: Node caches a failed module resolution for the life of the process, so generating afterwards and retrying resolves to the same failure.

Running the open-indexer-benchmark's Subgraph case found this: the fold that keeps a chain open-ended until every source on it stops was also applied to the first source, which always folded its endBlock away against the None the chain was created with. A manifest with one bounded data source indexed past its end block forever.

A subgraph's mappings are compiled by asc against @graphprotocol/graph-ts and then run by the shim, and nothing made those two agree — a gap showed up as green types and a runtime error. tsc cannot read graph-ts directly: it is AssemblyScript, and u64/i32/usize are not TypeScript types. Rewriting the primitives and dropping the AS decorators makes the signatures readable, and emitting declarations with --noCheck keeps the bodies — which mix integer widths in ways AS allows and TS does not — out of it. The generated declarations are committed alongside the graph-ts version they came from. conformance.ts then asserts every export is assignable to the real one. The 18 gaps it found are recorded as @ts-expect-error, which cleans itself up: closing a gap makes the directive unused, so the comment goes with the fix. TypedMap.mustGetEntry is the first one closed. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_016tA2D3BrcAJS4nME7noXh4
non-EVM subgraphs The 18 recorded gaps are down to 6, and those 6 are one difference reached six ways: graph-ts' BigInt extends Uint8Array and is constructed from a byte length, while this one is constructed from the value it holds. Mappings never call `new BigInt(...)` — they go through `BigInt.from*` — and the class is otherwise the same shape, bytes included. `envio dev` now runs the project's own `graph build`, which is the asc type check a subgraph already has, so a type error reads the same here as on Graph Node. Stamped against the inputs it reads, so it costs nothing on a restart that changed nothing. A NEAR or Cosmos subgraph now hears that Envio Subgraph indexes EVM chains, rather than that its network is unknown.

Found running the benchmark's state-aggregation case, whose mapping does the usual load, mutate, save. `changetype` erases the generated prototype, and with it the `save()` that knows which table to write back to — so the entity prototype tail remembers the type the row was loaded from and rebuilds it. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_016tA2D3BrcAJS4nME7noXh4
A CPU profile of the benchmark's event-stream case put ~7% of indexing time in building each BigInt's two's-complement representation — work added for type conformance that no mapping reads: graph codegen never indexes a BigInt, and the conversions that would are overridden here. The class still extends Uint8Array, so the type contract is unchanged; the bytes are just not filled. envio runs each handler twice over one payload, to preload and to execute, and the graph-ts conversion was repeated both times. Also drops ENVIO_SUBGRAPH_SKIP_TYPECHECK: the dev-loop type check is the project's own toolchain, and an escape hatch from it is an invitation to ship a subgraph that doesn't compile.

Review comments at @packages/cli/src/subgraph/assemblyscript.rs:
- Around line 194-202: Update visit_expression’s BinaryExpression handling to
preserve graph-ts numeric overloads for +, -, *, /, and %: dispatch to a
matching method such as div before coercing operands, and retain native
operators when no matching method exists. Keep BigInt_ and BigDecimal operations
from falling through to JavaScript coercion; alternatively, reject mappings that
use these operators with graph-ts values.
Review comments at @packages/envio-tests/test/SubgraphNullableField_test.res:
- Around line 104-112: Update handleNewOwner to read an undeclared entity member
only when the event nonce is 2, ensuring the proxy’s unknown-member guard is

the error identifying that undeclared member, rather than asserting that
processing resolves.
Review comments at @packages/envio/src/subgraph/hosts.ts:
- Around line 21-28: Update fetchBase64 to apply a finite timeout to the gateway

graph-ts overloads arithmetic and comparison on BigInt, BigDecimal and ByteArray, and asc compiles `a + b` on them to `a.plus(b)`, `a == b` to `a.equals(b)`. Run as JavaScript they coerced or compared identity, so `address == ZERO_ADDRESS` was always false and `(a + b).plus(c)` threw. The AssemblyScript pass now routes `+ - * / %`, `== != < <= > >=`, their compound assignments and unary `-` through one runtime helper, which calls the overload when both operands are objects declaring one and otherwise computes what AssemblyScript does — integer division included, which the old division-only helper handled.

A sparse block handler asked HyperSync for every block between the first and last it ran on — 4.5M blocks of headers for two timestamps a 100,000 block stride apart. Requested blocks are now grouped into ranges, merging gaps narrower than a response's worth of headers, and each range is queried on its own.

- The subgraph ABI reader accepts a build artifact's `{"abi": [...]}`, as
envio's own ABI parser does.
- `ipfs.cat` / `arweave.transactionData` time out after 30s, answer null
only for a 404, and throw on any other gateway failure so envio retries
it instead of caching a null.
- The "still refuses an undeclared member" test now reads one and asserts
the refusal.
- The networks-drift job doesn't persist the checkout's credentials for
the pull request's script.

…resses A template sharing a data source's name is folded into one envio contract. Its handlers kept names minted against the template alone, so an overload it listed by itself could bind to the data source's first overload. Each handler now takes the folded contract's name for its signature, and the two sides are gated by address: the data source's handlers run for its own address, the template's for the ones it created, as on graph-node. Also brings the compat doc in line with the implementation: host ops in the register pass, the replay round cap, and unknown directives.

Integrates main's native TypeScript module hooks, the Rust TUI, `envio start --chain` and the JSON-typed entity fields with subgraph mode: - The subgraph runtime registers its module hooks after main's TS hooks, so it claims a project's AssemblyScript mappings first; a subgraph project auto-loads no handler files, which also keeps main's handler type check off its mappings. - `envio_info` comes from main's `toEnvioInfo`, which now also drops the subgraph blob. - The AssemblyScript pass moves to main's oxc 0.144: its new AST builder and the split export-declaration nodes.

Review comments at @.github/workflows/subgraph-nightly.yml:
- Line 28: Set persist-credentials to false on the actions/checkout step in the
nightly workflow so the corpus suite’s third-party code cannot access the
persisted GitHub token; no later step requires authenticated Git operations.
Review comments at @docs/subgraph-compat.md:
- Line 54: Update the “A template sharing a data source’s name” entry in the
compatibility table to clarify that folding merges configuration and events but
not handler routing: static data-source handlers apply only to the declared
static address, while template handlers apply to dynamically created template
addresses.
- Around line 331-333: Update the ENVIO_SUBGRAPH_RPC documentation to state that
its ordered RPC entries are fallback endpoints, not per-chain endpoints, and
that translation rejects a non-empty value when the subgraph indexes multiple
chains.
Review comments at @packages/cli/src/subgraph/mod.rs:
- Around line 40-46: Update RECEIPT_TRANSACTION_FIELDS to include Hash,
TransactionIndex, and Root so receipt selection fetches every transaction field
read by RECEIPT_SHAPE.
Review comments at @packages/envio/src/subgraph/graph-ts.ts:
- Around line 949-951: Update the timestamp branches in toRow and toEntity to
convert values only when they are non-null; let null or undefined values
continue through the existing null-handling conversion paths. Apply the guard to
both store directions so nullable Timestamp fields save and load without
invoking timestamp methods on null values.
Review comments at @packages/envio/src/subgraph/hosts.ts:
- Around line 85-94: Update the ENS lookup callback so it returns null only for
a confirmed rainbow-table miss; throw on network errors, server or rate-limit
responses, and malformed JSON so failed lookups are retried rather than cached.
Check how ensrainbow represents misses before choosing the response or body
condition, and add a timeout using the existing timeout configuration where
available.
Review comments at @packages/envio/src/subgraph/runtime.ts:
- Around line 550-593: Prevent template block handlers from being registered as
chain-wide handlers in the blockHandlers loop; reject them during manifest
translation or filter registration by template instance address. Ensure folded
sources cannot register duplicate handlers with the same name and handler.

- A nullable `Timestamp` set to null saves and loads as null; both store directions converted it unconditionally and threw. - A block handler on a template is refused at translation: graph-node runs one per created instance, and envio would run it chain-wide. - `receipt: true` selects the transaction hash, index and root, which a mapping can read off `event.receipt` without the usage scan seeing a read of `event.transaction`. - `ens.nameByHash` answers null only for ENSRainbow's 404/400; any other failure throws so the batch retries instead of caching a miss. The lookup also gets the gateway timeout. - The nightly checkout drops its persisted token and installs the pinned toolchain, as main's workflows do. - The compat doc states the folded-template routing, the single-chain `ENVIO_SUBGRAPH_RPC` and the new refusal.

HyperSync started serving it, which turns the hypersync-health-check red on every branch until the Network enum lists it. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01DBgCCjPmPvx6C2UcTWiquc
Each with a test that reproduces it from the outside: - F20: graph-cli before 0.93 ships CommonJS; the codegen worker now finds the command class one level down, and names a missing one itself rather than blaming graph-cli. - F24: a name imported twice — the same generated event class from two contracts' bindings — no longer fails to load: the first import keeps it. - F4/F23: envio exits on a handler error and has no batch retry, so every host op (calls, balances, timestamps, IPFS, Arweave, ENS) now runs through `untilAnswered`: a per-attempt deadline and exponential backoff on timeouts, network errors, 429/5xx and JSON-RPC rate limits, as graph-node does. The RPC gate holds a slot at most the deadline, so requests that never settle can't stall every call behind them. Deadline and backoff are tunable through ENVIO_SUBGRAPH_REQUEST_TIMEOUT_MS / _RETRY_BACKOFF_MS. - F9: in subgraph mode, an event of an address registered in the very block it was logged in runs after that block's other items, as graph-node runs a new data source's creation-block triggers. - F5: the project's codegen script runs step by step, `graph codegen` in-process and the rest in a shell, so Lido's extra step isn't lost. - F21: BigDecimal reproduces graph-node's bigdecimal 0.1.2 normalization to 34 significant digits exactly, checked against 400 vectors that crate computes (generator committed alongside). - F22: a height poll that doesn't answer is given up on after 10s, not 60.

Mark creation-block events before cleanup.
When a response registers an address, handleQueryResult adds its creation block before cleanup. The cleanup uses the previous buffer frontier. A bounded response can advance that frontier past the registration block before the matching event is fetched. The cleanup then deletes the entry, so the matching event keeps log-index order and can run before its creator.
Suggested fix
let markCreationBlockEvents = (creationBlocks: dict<int>, ~newItems, ~fetchedThrough) => {
- creationBlocks
- ->Dict.toArray
- ->Array.forEach(((key, block)) =>
- if block < fetchedThrough {
- creationBlocks->Utils.Dict.deleteInPlace(key)
- }
- )
newItems->Array.forEach(item =>
if item->Internal.getItemKind === 0 {
let eventItem = item->Internal.castUnsafeEventItem
let key = creationBlockKey(
~contractName=eventItem.onEventRegistration.eventConfig.contractName,
~address=eventItem.payload->Internal.getPayloadSrcAddress,
)
if creationBlocks->Utils.Dict.dangerouslyGetNonOption(key) === Some(eventItem.blockNumber) {
item->Internal.markItemRunsAfterBlock(true)

Update markCreationBlockEvents to process newItems and mark matching
creation-block events before deleting entries older than fetchedThrough. Keep
the existing matching logic and cleanup condition unchanged, but move cleanup
after event marking so entries remain available for events in the current
response.

Uniswap v2 ran 4.3x slower than on envio@3.14.0-subgraph, CPU-bound (retest-06). A profile put 55% of the time in BigDecimal: normalize() padded every coefficient to 34 digits and stripped the zeros off again one bigint division at a time; powers of ten were recomputed with 10n ** n; the bit length came from a binary string; division appended its 100 digits one division each; and every value eagerly built the BigNumber it carries, from a printed string. exponentToBigDecimal's times(10) loop alone was 40% of the run. Same values, by different means: a coefficient of 34 digits or fewer only loses its own trailing zeros; powers of ten come from a table; a positive's digit count starts from log10; division is one division of num * 10 ** extra (an early stop shows as trailing zeros); comparisons work on the coefficients; the BigNumber is made on first use and carries its decimal, so an entity read back from memory isn't printed and parsed again; repeated literals parse once. The second normalization of each result stays: graph-node normalizes a value again whenever it crosses back from AssemblyScript into its host (FromAscObj -> BigDecimal::new), and that pass changes a negative the first left at 35 digits. The bigdecimal 0.1.2 vector generator now models that round trip and adds 511 vectors for the shapes a fast path could get wrong (powers of ten, trailing zeros, 33-36 digit results, negatives at a power of two, carries, exact and repeating division, zeros): 911 vectors, all equal. A differential run against the previous code agreed on 1.6M operations. Uniswap v2 window 10,000,834 to 10,250,000 (unmodified repo, same box and proxy): 383 ev/s before (150,690 events in 420 s, not finished), 1,654 ev/s after (window of 411,332 events done in 276 s); published 3.14.0-subgraph 1,731 ev/s, 273 s. envio subgraph diff vs the network (GmSczqdC) at 10,250,000: 15/15 types, 427,478 ids, 1,139 sampled, 0 field mismatches (the published build: 720). This changes #1626's own graph-node-decimal.ts (F21, 8566fa6). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…85% of 2026 repos) (#1759) * subgraph: contract calls by name from pre-0.18 bindings graph-cli before 0.18 (mapping apiVersion 0.0.3 and older) generates `super.call("ownerOf", [params])` and `super.tryCall(...)` with no function signature; graph-node then takes the first function of that name in the data source's ABI (chain/ethereum/src/runtime/ runtime_adapter.rs: `function_signature: None` → `contract.function(name)`). The shim only took the three-argument form of later graph-ts and failed with 'Unreadable contract call signature ""'. SmartContract.call/tryCall now accept the two-argument form; the runtime installs a lookup that reads the manifest's ABI of that name and builds graph codegen's `name(inputs):(outputs)` signature for the first function so named. A name the ABI lacks is an error, as on graph-node. Test: SubgraphLegacyContractCall_test.res Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: two handlers on one event both run, in manifest order graph-node's handlers_for_log returns every handler of a data source whose event matches a log and runs them in manifest order. The translation gave each extra handler of an event its own envio event (`Ping_1`), which envio refuses as two events "the indexer can't tell apart", so the subgraph didn't start. envio runs every registration on an event since #1469, so a repeated event now registers its handler on the first one's event; the event selects receipt fields when any of its handlers asks for them. Groundwork for swaap-labs/swaap-subgraph-v1 (a subgraph from a hosted subgraph platform), which hangs a dozen handlers on LOG_CALL. Test: SubgraphSameEventTwice. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: block timestamps and headers HyperSync doesn't answer are asked of RPC concurrently On a chain HyperSync doesn't serve, a block handler's block.timestamp (and header) comes from ENVIO_SUBGRAPH_RPC, one eth_getBlockByNumber per block, and the fallback awaited them one after another: on BlockDAG (evm-1404) a handler on every block took 277 s to commit its first 500 blocks. graph-node fetches a range's blocks concurrently; the fallback now issues them at once, bounded by the RPC client's requests in flight (ENVIO_SUBGRAPH_RPC_CONCURRENCY). Test: SubgraphRpcBlockTimestamps_test.res (mock RPC records the most eth_getBlockByNumber requests in flight). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: read a pre-0.22 transaction.gasUsed as the gas limit graph-ts before 0.22 named the transaction's sixth field gasUsed; graph-node fills that slot with the transaction's gas limit (gas_limit in every AscEthereumTransaction_0_0_*, chain/ethereum/src/runtime/abi.rs), which later graph-ts calls gasLimit. Uniswap v3's 2022 mappings (arbitrum-minimal) store event.transaction.gasUsed on every Transaction, and it read null, so the batch write failed on the non-null column. The shim's transaction now carries gasUsed from envio's gas field, and the field scan selects gas for it. Test: SubgraphLegacyTransactionGasUsed_test.res, cargo test selects_the_gas_limit_for_a_pre_0_22_gas_used. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: load a mapping import that exists only in another case Omni-DeFi's mappings import `../generated/staking/staking`, and graph codegen writes `generated/Staking/Staking.ts` for the data source `Staking`. asc resolves that on the macOS or Windows filesystem the subgraph builds and deploys from; Node on Linux didn't find the module, and the mapping failed to load. A relative import from a project file that Node can't find is now matched against the filesystem one path component at a time: when each missing component has exactly one entry differing from it only in case, that file is loaded, with one warning per import. Imports into node_modules and files outside the project are left alone. Test: SubgraphImportCase_test.res (failed to load the mapping before). Omni-DeFi/subgraphs (mode-testnet, hosted): failed to load src/staking.ts; now indexes (44 events to block 20,032,984 in 150 s).

Here the endpoint was taken on trust: one of the wrong chain answered a mapping's contract calls with another chain's state, or on a chain HyperSync doesn't serve, indexed another chain outright. At startup the endpoint is now asked its eth_chainId and refused on a mismatch, naming both chains; an endpoint that doesn't answer is left to the runtime's retries. Test: subgraph::project_tests::refuses_an_rpc_endpoint_of_another_chain. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: say why a generated file a mapping imports doesn't exist graph codegen writes schema.ts, templates.ts, <data source>/<ABI>.ts and templates/<template>/<ABI>.ts for the manifest it runs on, and no index.ts. A mapping importing anything else fails `graph build` too (asc TS6054), and builds only on a machine whose tree is left from an earlier manifest: revert's uni-v3-staker imports generated/UniV3Staker/ after renaming its data sources UniV3Staker1.0.0/1.0.2; WOOFi's per-chain manifests import data sources only another chain's manifest declares; tornado imports a hand-written generated/index.ts. envio reported only Node's "Cannot find module"/"Directory import"; it now adds which data source, template or ABI the manifest lacks and what it has. Test: SubgraphGeneratedNotWritten_test.res Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: a rollup reads every group's carried values in one lookup A cumulative aggregate carries each group's previous bucket forward (graph-node rollup.rs, `cumulative: true`), so a rollup needs every group's carried values. They were read one `getSync` at a time, and each miss suspends the sync bridge: the handler that crossed a bucket's end ran once per group, every replay redoing the rollup. graph-node's aggregation example (graphprotocol/graph-tooling examples/aggregations, a group per block number modulo 1000) replayed block 930's handler 934 times and committed nothing in three minutes. The rollup state rows now carry `aggregation` = `<Aggregation>|<interval>` (indexed), and a rollup reads its groups' rows with one getWhereSync: at most one round for all of them. Test: SubgraphAggregationGroups_test.res, the same 2,000 rows rolled up as one group and as a group each (4.8 s vs 0.26 s before; now comparable). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: fail a save that leaves a non-null field unset, as graph-node does graph-node validates a saved entity, merged onto the stored one with explicit nulls removed, against the schema (EntityCache::set -> Entity::validate) and fails the handler with "Entity T[id]: missing value for non-nullable field `f`". envio accepted the save and the batch write failed later, on Postgres' NOT NULL or on a null it couldn't serialize, with nothing pointing at the mapping: Opolis' ensureOpolisPayToken saves an OpolisPayToken without createdAt: BigInt!. The translated schema now records which fields are declared non-null, and store.set checks the merged row before writing it (not in the register pass). Two tests saved entities that graph-node would refuse: the receipt-logs mapping now stores a fallback name for an unparsed log, and the changetype test seeds an entity type without required fields. Test: SubgraphMissingRequiredField_test.res. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: refresh The Graph's networks registry snapshot to 0.8.7 The registry added aliases since the snapshot was taken (arctest for arc-testnet, basesepolia, unisepolia, zksyncera), and the CI drift check (sync-graph-networks.mjs --check) fails on it. Refreshed with the script. Test: subgraph::manifest::tests::maps_graph_network_names_to_chain_ids (arctest, basesepolia). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: roll up aggregations in the execute pass only Preload runs a batch's handlers with their writes dropped, so each one read the rollup clock as the previous batch left it, found its block past the end of that clock's bucket, and rolled the bucket up again: a batch of 5,000 block handlers redid one rollup 5,000 times, ten aggregations each in graph-node's aggregation example, which then committed nothing from its second batch on. The execute pass, where the clock advances handler by handler, rolls up as graph-node's Layout::rollup does; preload still reads the clock, so the execute pass finds it in memory. graphprotocol/graph-tooling examples/aggregations (mainnet, block handler on every block, five aggregations, cumulative groups): 0 blocks committed in 180 s before; 345,000 blocks in 90 s after, with this and the previous commit. Test: SubgraphAggregationPreload_test.res, a batch after a split run vs the same rows in one run (2.5 s vs 0.35 s before; now comparable). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: run the codegen script's steps that write the manifest, before translating cope-market's erc4626-vault commits subgraph.template.yaml and writes subgraph.yaml in the first step of its codegen script: `"codegen": "node scripts/build-manifest.mjs ${NETWORK:-arc-testnet} && graph codegen"`. envio runs a codegen script's other steps anyway (§6a), but the missing manifest stopped it at translation, before it got there. When the manifest is missing and no mustache script renders it, the codegen script's steps before `graph codegen` now run first, in the package directory with its bins on PATH. A variable a step reads is set to ENVIO_SUBGRAPH_NETWORK when that is set; unset, the script's default applies. The manifest is recorded as envio's, so a later start writes it again, and the runtime's codegen skips the steps already run, which would otherwise write the script's default network over the one picked. A failing step stops envio with the script's own error. The "config.yaml not found" hint no longer offers a `*.template.yaml` as a manifest to run. Tests: project_tests::runs_the_codegen_steps_that_write_the_manifest, SubgraphCodegenPrelude_test.res (graph codegen got the default network's manifest without the skip). cope-market/subgraphs erc4626-vault (arc-testnet), unmodified: "Found subgraph.template.yaml but no subgraph.yaml" before; now starts and indexes. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: a codegen step's own manifest goes into the tree balancer/gauges-subgraph builds one tree from two manifests: `graph codegen subgraph.yaml --output-dir src/types/ && graph codegen subgraph.arbitrum.yaml --output-dir src/types/`, and its mappings import data sources only the arbitrum manifest declares. envio ran every `graph codegen` step of the codegen script on its own manifest, dropping the one the step names, so that half was never written; the bundled codegen wrote only envio's manifest. A step naming another manifest of the project now generates that one, into the directory the step names; envio's own manifest is generated where a step names it or no manifest at all, and last otherwise, so its files win. The bundled codegen follows the same plan. Test: SubgraphCodegenScriptManifests_test.res (graph-cli), SubgraphBundledCodegenManifests_test.res (bundled) Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: match an anonymous event on its topic0, decoded from all its topics graph-node keys an event handler on `topic0` when the manifest gives one (MappingEventHandler::topic0) and parses an anonymous event's log with every topic an indexed param. Balancer v1's pools emit an anonymous `LOG_CALL(bytes4 indexed sig, address indexed caller, bytes data)` and their subgraphs hang one handler per called selector on it; translation refused those as "topic0 is not the event signature's hash". - manifest: a topic0 other than the signature's hash is kept on the handler (a value that isn't a 32-byte word is an unknown-error). - translation: on an event the ABI declares anonymous, each (event, topic0) is its own envio event carrying that topic0; elsewhere, or with topic1-3 filters, it is still refused. - config: an EVM event config may carry a `topic0` (not in config.yaml's schema): on an anonymous ABI event it becomes the sighash and the event is marked anonymous in the internal config. - runtime: an anonymous event's topic count is its indexed params alone, and the decoder reads a registration whose topic count equals its indexed params as anonymous (no signature topic). swaap-labs/swaap-subgraph-v1, a subgraph from a hosted subgraph platform: indexes on polygon (setSwapFee/finalize/bind decode to the values on chain) until its next blocker, a Transaction saved without its non-null gasUsed. Tests: SubgraphAnonymousTopic0, evm_hypersync_source::decode::tests::decodes_an_anonymous_event_from_all_of_its_topics, subgraph::manifest keeps_a_topic0_other_than_the_signature_hash and refuses_a_topic0_that_is_not_a_word, and the translation's topic0 test. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: preload a handler again once the entity it read as absent is created Preload runs a batch's handlers against the store as it was before the batch, so a handler reading an entity an earlier event of the same batch creates (a v3 pool's Mint after its PoolCreated) finds nothing, throws or returns early, and makes none of its contract calls. The execute pass then asks them one event at a time: a round trip per call, in series. Preload reads that find an entity absent are now remembered per item. When execute creates that entity, those items are preloaded again against the current store, as long as they are within ENVIO_SUBGRAPH_PRELOAD_LOOKAHEAD (default 256, 0 = off) items of the one executing; an item whose preloads already ran for 20 ms of CPU is not preloaded again. Subgraph mode only. Preload never writes, and every value it fetches is keyed by its full input, so what execute computes is unchanged. Test: SubgraphPreloadLookahead_test (16 handlers reading a pool created earlier in the batch: calls in flight at once 1 -> 16, results equal). sushiswap v3 (mainnet, from its start block), 180 s cap, 200 ms per RPC request: 44 -> 1,044 events committed; execute rounds waiting on eth_call 489 (100 s) -> 91 (33 s). Row-for-row equal to a lookahead-off run over the same 544 events (23 tables, 0 differing rows). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: log each codegen step run for the manifest, and test that nothing else runs The codegen script's steps that run before translation (ca39bb2b3) now print a line naming each step, and the variables set from ENVIO_SUBGRAPH_NETWORK, before running it. A test pins the scope: with preinstall, install, postinstall, prepare, build and manifest scripts that would write the manifest, and a codegen script that is only `graph codegen`, none runs, and the error names the one that looks like a writer. §6d says so. Test: project_tests::runs_no_script_but_the_codegen_scripts_steps. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: toI32/toI64 wrap a value whose high bytes are sign padding graph-ts' ByteArray.toI32()/toI64(), which BigInt's defer to (common/collections.ts), assert only that the bytes past the width equal the sign padding of the last byte, then read the low bytes as two's complement. A uint32 of 2^32 - 1 is `ff ff ff ff 00` and reads as -1, and any value from -2^32 to 2^32 - 1 (2^64 for i64) wraps into the signed range. The shim refused everything outside i32 (and BigInt.toI64 returned values past i64 unchecked). poa-box/subgraph-pop calls `event.params.maxMembers.toI32()` on `type(uint32).max` in handleSubjectCreated: the run stopped there; now synced (1,307 events in the window). Test: SubgraphBigIntSignedWrap_test.res. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: build a manifest that names no network for the network the repo's build passes iExec's PoCo subgraph names no network in subgraph.yaml and keeps addresses in networks.json; its build runs `graph build --network ${NETWORK_NAME:-arbitrum-sepolia}`. A bare `envio start` stopped at "declares no indexable data source", asking for ENVIO_SUBGRAPH_NETWORK. When ENVIO_SUBGRAPH_NETWORK is unset, a data source names no network and networks.json exists, the network is now the one the package.json scripts pass `--network` — a `${VAR:-default}` default or a literal — when they all agree on it and networks.json has it.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: rerun a mapping's top-level code for every trigger graph-node instantiates the mapping's WASM module for every trigger (runtime/wasm/src/mapping.rs: instantiate_module before each handle_trigger): the start function runs again in that trigger's context and no global keeps what an earlier handler left in it. envio evaluated each file once, so module state leaked across events, replays and the preload pass: SporkDAO numbers TransferData from a module counter, morpho-blue caches its protocol entity in a module variable, fabcrowd keeps a per-block cache; and a top-level dataSource.context() read the data source the file was loaded for, not the current instance's. The post-transform pass now splits a module into stages. Classes whose definition runs no code, constant globals and globals built only from graph-ts values (BigInt.fromI32(0), Address.fromString(...)) are set once in __envio_static, as before. Every other top-level statement moves, in order, into __envio_start, a declaration becoming an assignment to its var; it runs as the module loads (a failure there is left to the first trigger, which runs it in a real context) and again through __envio_init(generation), which first calls the same function of each relative module imported or re-exported. The runtime calls the mapping's __envio_init as every handler, register or file data source round starts. Test: SubgraphModuleState_test.res, cargo test splits_a_module_into_static_and_per_trigger_stages. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: write generated files only another manifest declares graph codegen never cleans its output directory, so the tree a project with one manifest per network was built with holds the data sources of every manifest it generated, and the mappings import them: WOOFi's bsc mappings import generated/WooRouterV1_3/ (only avax.yaml declares it), DODO's bsc ones src/types/dodoex/DVMFactory/ (mainnet), flaunch's generated/BuyBackAndBurnFlay/ (base-sepolia). `graph build` of that one manifest fails on a clean checkout (asc TS6054), but the deployed subgraph was compiled against the developer's tree. After codegen (graph-cli or bundled), the generated files the mappings still miss are written from the first other manifest of the project that declares that data source or template with that ABI (codegen::fill_from_manifests, exported as subgraphFillGenerated), with a warning naming the files, the manifest and why. Only missing files are written; schema.ts and envio's own manifest's files are never touched. ENVIO_SUBGRAPH_CODEGEN=graph-cli keeps graph-cli's behaviour. WOOFi bsc (with its documented constants copy) and DODO bsc now index. Test: SubgraphGeneratedFromSiblingManifest_test.res Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: on a chain HyperSync doesn't serve, read block headers and receipt logs from RPC alone A block handler's timestamp and header, and event.receipt.logs, asked <chain>.hypersync.xyz first and fell back to ENVIO_SUBGRAPH_RPC on failure, even for a chain HyperSync doesn't serve. A refused connection costs little, but where a firewall drops it instead every batch waited out the request deadline (30 s) first. The translation knows which chains HyperSync serves; it now hands the runtime the others (rpcOnlyChains), whose headers and receipts go to the RPC directly. Test: SubgraphRpcBlockTimestamps_test.res (a HyperSync host that never answers is not asked). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: read ipfs.cat's argument as graph-node's ContentPath graph-node parses the link handed to `ipfs.cat`, `ipfs.map` and a file data source with `ContentPath::new` (graph/src/ipfs/content_path.rs): `<CID>[/<path>]`, `/ipfs/…`, `ipfs://…`, or an http(s) URL with `/ipfs/<CID>…` in its path or the CID in `?arg=`; an empty string, a non-CID or a path with a query fail to parse, and `ipfs.cat` returns null for them (runtime/wasm/src/module/context.rs) while `ipfs.map` fails. The shim sent anything it couldn't normalize to the gateway as is: SoulSystemProtocol/SoulSystem-Subgraph's `ipfs.cat("")` (the last segment of an empty URI) fetched the gateway's root, which answered 429, and the run stalled asking again; a gateway URL was appended to the gateway. SubgraphIpfs_test.res used `QmMissing`/`QmFlaky`, which graph-node refuses as CIDs; they are CIDv0-shaped now. Test: SubgraphIpfsContentPath_test.res. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: render through the npm-run scripts a deployment script calls, with its variables Aave's protocol-subgraphs writes subgraph.yaml from one script per deployment: `"deploy:hosted:mainnet-v3": "VERSION=v3 BLOCKCHAIN=v3 NETWORK=mainnet env-cmd npm run prepare:subgraph && …"`, where `prepare:subgraph` is `mustache ./config/${NETWORK}-${VERSION}.json ./templates/${BLOCKCHAIN}.subgraph.template.yaml > subgraph.yaml && … npm run generate:schema && npm run subgraph:codegen`, and `generate:schema` copies `schemas/${VERSION}.schema.graphql` to schema.graphql. envio saw three unbound variables and named the script instead of rendering. A step that is `npm run <script>` (`yarn <script>`, `pnpm <script>`) is now read as that script's steps, with the variables the call sets bound in them, as a shell hands them on; `cp <from> <to>` is repeated, and `env-cmd` is a wrapper. A script that only calls the one that renders (zora's `codegen` runs `yarn gen-yaml-config`) is dropped for it, and the runtime's codegen skips every script the rendering one inlined. Also fixed: a mustache view holding a variable (`mustache config/$NETWORK.json …`) was taken for an option. Test: project_tests::renders_through_the_scripts_a_deployment_script_runs (names the network per deployment: mainnet-v3, arbitrum-v3). Aave v3 mainnet, unmodified, ENVIO_SUBGRAPH_NETWORK=mainnet-v3: "no subgraph.yaml" before; now renders, copies its schema and indexes (57,751 events, blocks 16.29M -> 16.80M in 180 s). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: send queued RPC requests as JSON-RPC batches Every contract call, balance and block lookup was its own HTTP request, so a batch's thousands of calls cost thousands of round trips through 48 connections. Requests that queue while those are busy now leave together as one JSON-RPC batch of up to ENVIO_SUBGRAPH_RPC_BATCH (default 32; 1 = off). Each request keeps the answer it would get alone: answers are matched by id (in any order), a JSON-RPC error stays that item's error, so a revert reaches only the try_ call that reverted, and an HTTP failure fails the items it carried for untilAnswered to ask again. An endpoint that refuses a batch (HTTP 4xx, an error object in place of the array, or a per-item "batch of more than N requests" as dRPC's free plan answers) gets smaller batches from then on, down to plain single requests. viem's own batching matches answers by position and can't shrink, so the transport is built on its HTTP client and error types instead. Test: SubgraphRpcBatch_test (40 calls, one reverting: one HTTP request per >= 4 calls, results equal; all answered by an endpoint allowing 3 per batch and by one that takes no batches). sushiswap v3 at 200 ms per HTTP request, 180 s: HTTP requests 1,899 -> 335 for ~1,900 calls, 544 -> 1,044 events; row-for-row equal to a run without (23 tables). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: Bytes.empty() is four zero bytes, as graph-ts builds it graph-ts' `ByteArray.empty()` returns `ByteArray.fromI32(0)` and `Bytes.empty()` casts it (common/collections.ts, unchanged from 0.27 to 0.38): four zero bytes. The shim returned an empty array, so every field a mapping defaults with `Bytes.empty()` stored `0x` where graph-node stores `0x00000000`, and `Bytes.empty().length` read 0 instead of 4. 148 mapping files in modern's 2025-26 survey call it, among them KlimaDAO's polygon-digital-carbon, valory-xyz/autonolas-subgraph and Proof-Of-Humanity v2.

The host-op retry only knew rate-limit codes and stopped the run on it: Miljan9602/dragonswap-subgraph-sei's register pass failed on one symbol() call ('An internal error was received') that answered when asked again. graph-node retries every eth_call error that isn't a revert (chain/ethereum/src/call_helper.rs interpret_eth_call_error).

On JavaScript's Map, Intent-X's analytics loop over dictionary.keys().length ran zero times and Reserve's RSR_CHAINLINK_CONTRACT_ADDRESS[network] read undefined. The transform turns new Map / new Set (when the module doesn't bind its own) into __envio_Map / __envio_Set, which the runtime installs: Map and Set subclasses with those methods, behind a proxy that serves a property access that isn't a member as the [] operator (a numeric spelling as a number key when the collection holds numbers). Test: SubgraphAsMap_test.res, cargo test builds_assemblyscript_maps_and_sets. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: bundled codegen sets zero values in constructors as graph-cli 0.22-0.29 did graph-cli 0.22.0 added `_generateDefaultFieldValues` (src/codegen/schema.js): a new entity's constructor sets every non-nullable, non-derived field to a zero value from ASSEMBLYSCRIPT_TO_VALUE ("", 0, false, BigInt.zero(), BigDecimal.zero(), Bytes.empty(), new Array(0)). 0.26.1, 0.27.1, 0.28.2 and 0.29.1, released together, dropped it. A subgraph built with one saves those zeros on graph-node, and a fresh instance saved over a stored entity resets the fields it didn't set. Those releases no longer install (a dead git dependency), so envio writes the generated code itself, and wrote it the newer way: fields stayed null. The bundled codegen now reads the project's graph-cli release (installed, else its lockfile's, else its package.json range at the newest patch of the minor) and writes the zero values for the releases that did. swaap-labs/swaap-subgraph-v1 (a subgraph from a hosted subgraph platform, graph-cli 0.25.3): ok on polygon, 14,010 events in 96 s.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: a save missing a non-nullable field fails as graph-node's does graph-node's EntityCache::set validates every save (Entity::validate): an update that sets every non-nullable field passes as it is, otherwise it is merged onto the stored entity and the first non-nullable field still missing fails the handler with "Entity T[id]: missing value for non-nullable field `f`". envio wrote such an entity and failed later, at the batch write, with whatever the column made of the null (a NOT NULL violation, "Cannot read properties of null" from a BigInt column). The schema translation now marks each field's top-level non-null, and store.set checks it the way graph-node does (a null counts as set in the update alone; the merge drops it), before writing. Subgraphs from hosted subgraph platforms that now stop where graph-node stops, with graph-node's message: kalidao/kali-subgraph (a tribute Proposal saved with two fields), mememan-anon/launchpad-subgraph (PandaPool without baseToken). 12 ok hosted subgraphs re-run: no change.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: BigInt.toU32/toU64 read the BigInt's own byte width graph-ts' BigInt.toU32()/toU64() defer to ByteArray.toU32()/toU64() (common/collections.ts): the BigInt's bytes, zero-padded, overflowing only when a byte past the width is set. A BigInt is its bytes, and how many it has depends on how it was made: the host returns minimal two's complement (-1 is 0xff, so 255), while `BigInt.fromI32(-1)` is the four bytes `ByteArray.fromI32` writes (so 4294967295), `fromI64` eight. The shim used the minimal width for every BigInt, and the existing test pinned 255 for `BigInt.fromI32(-1).toU32()`; it now pins graph-ts' values. The shim already tracks each BigInt's width for `byteLength`. clober-dex/v2-subgraph encodes order ids with `BigInt.fromI32(tick).toU32()`; its `(x << 8) >> 8` on that u32 still needs AssemblyScript's unsigned shifts (queued for the transform). Test: SubgraphBigIntUnsigned_test.res. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: render the template --config names, and name the script that renders one `ENVIO_CONFIG=subgraph.template.yaml` (the corpus's first runs) parsed the template as a manifest: "startBlock has to be a number" for `startBlock: {{startBlock}}`, or, where the template isn't YAML until rendered, "not a valid yaml or the ecosystem field is not a string". A --config that is a mustache template now resolves to the manifest a repeatable script renders from it, and runs that; otherwise the error says it is a template, names the scripts that write the manifest, and asks for the manifest's path. A script is also named as a writer when it runs a repo file (`ts-node ./script/build`, `node ops/render.js`, `./build.sh`) whose source, or a module it imports, mentions a template or the manifest: envio reads those files, never runs them. Uniswap v2/v3, hop and pangolin now get their build script named instead of "config.yaml not found". Tests: project_tests::renders_the_template_config_names_or_says_it_is_one; runs_no_script_but_the_codegen_scripts_steps now expects every writer named. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: leave out a handler whose event no log can carry, as graph-node never runs it A log holds at most four topics, the first the signature's hash, so an event the ABI gives four indexed parameters never decodes from one: graph-node skips its handler for every log with that topic0 (chain/ethereum/src/data_source.rs, 'Skipping handler because the event parameters do not match the event signature'). envio's log decoder refused the registration instead and the indexer stopped at startup ('topic_count must be 1..=4, got 5'; Agentic-Trust-Layer/agent-indexer declares ERC-6909's Transfer that way). Such a handler is now left out of the config, with a startup warning naming it. Test: subgraph::tests::drops_a_handler_for_an_event_no_log_can_carry. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: resolve workspace packages without an install A monorepo's subgraph imports its shared mapping code by package name: enzyme's mappings import `@enzymefinance/subgraph-utils`, its workspace package `packages/utils` (`"main": "index.ts"`), which only the workspace install links into node_modules. Without that install (one that died on a dead git dependency, a builder that runs none) the name resolved nowhere, envio tried to fetch it from npm, where it is absent or someone else's, and the usage scan missed the fields it reads. subgraph::workspace finds the nearest workspace (package.json `workspaces`, yarn's `{packages}`, pnpm-workspace.yaml `packages`; globs with `*`, `**` and `!`) and its packages by name, as npm, yarn and pnpm link them. A bare import node_modules can't resolve now resolves in the workspace's package (its `main`, else asc's candidates) before any npm-fetched copy, workspace packages are never fetched, and the usage scan follows them too.

Keeping both would conflict in schema.rs, graph-ts.ts and the test file at integration. The changetype test keeps seeding an entity type without required fields, which either check accepts. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: implement ethereum.decodeParams (apiVersion 0.0.10) graph-node v0.45 adds the `ethereum.decodeParams(types, data)` host function for apiVersion 0.0.10 (runtime/wasm/src/host_exports.rs `ethereum_decode_params`, NEWS.md): alloy's `abi_decode_params`, which reads a top-level tuple's fields as a sequence of parameters, the way calldata holds them (Gnosis Safe's `execTransaction`), where `ethereum.decode` expects one value behind an offset word. A type that isn't a tuple decodes as `decode` does; a failure is null. apiVersion 0.0.10 manifests are accepted since d9c9b403c; a mapping that called `decodeParams` was refused as an unknown graph-ts API.

Saves within one block merge in the entity cache first. graph-node refuses it on a mutable type ("skipDuplicates requires immutable: true"). The translator refused the argument as unknown. It now records such types (`skipDuplicateEntities` in the runtime config), refuses the argument on a mutable type, and the save path skips a write when the row exists but wasn't written in this block.

JavaScript's bitwise operators give a signed int32, so Clober's 24-bit order tick (tick.toU32() << 8) >> 8 came out negative, Ekubo's big-endian word (data[i] as u32) << 24 | ... too, and FIL-Builders' (x as u32) >> 16 shifted in ones. The transform knows an expression is a u32 when its name is declared so (a parameter, local or global, bound once), it is x.toU32(), x as u32, a call of a module function declared to return u32, or such a bit operation itself; << and >> on one, and |, &, ^ with one on either side, go through __envio_op.*_u32, and so do their compound assignments to a u32 name.

The shim asked a failing gateway again forever, so a mapping whose file every gateway refuses never got past that event: SoulSystemProtocol and RequestNetwork's storage subgraph sat at 0 commits behind 429s. Now the effect retries for up to ENVIO_SUBGRAPH_IPFS_TIMEOUT_MS (default 60000), then answers null, uncached and warned, so a later ask fetches anew. `ipfs.map` gets an effect of its own that keeps waiting: graph-node fails that handler and retries the block. untilAnswered gained a `budgetMs` option for it.

The bundled codegen always wrote the new name, so a project pinning an older graph-cli (Multyr's 0.70: `ExecComputeScoresCallValue0Struct`) got classes its mappings don't know. codegen::GraphCli reads the graph-cli Node would resolve from the manifest, else the one the nearest package.json declares, and the bundled codegen names the class as that release does; the latest when neither says.

The bundled codegen chose by the installed graph-ts alone, so a project pinning an older graph-cli got loaders (and no setter, which an old mapping assigning the field throws on), and one with a newer graph-cli but an old graph-ts got arrays (dataunions: graph-cli 0.73, graph-ts 0.29).

Test: subgraph::manifest::tests::resolves_the_network_slugs_other_hosts_use. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: read render scripts in the packages above the manifest too A workspace root's scripts can write a package's manifest: `"prepare:matic": "mustache config/matic.json subgraphs/exchange/template.yaml > subgraphs/exchange/subgraph.yaml"`; pangolin's root `template` script writes src/<subgraph>/subgraph.yaml through a node script. Only the manifest's own package.json was read, so the corpus run in src/blocks got the generic "Found subgraph.template.yaml" error. Plans and writers now come from the manifest's package.json and those of the packages above it, up to the repository root; each plan runs in its own package directory, and a writer from a parent package is named with it. Test: project_tests::renders_the_manifest_a_parent_package_script_writes. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: halve RPC requests in flight when the endpoint rate-limits A public endpoint answers 429 past the few requests it serves at once. At 48 requests in flight most of every wave was refused, and each refused call backed off on its own, for longer and longer, so a batch could stall for minutes while the endpoint was mostly answering 429s. When the endpoint says "slow down" (HTTP 429, or a JSON-RPC rate-limit error such as -32005), the requests in flight and the calls per JSON-RPC batch are halved, once per wave: refusals of requests sent before the last cut don't cut again. Both grow back by one per round of answers, up to ENVIO_SUBGRAPH_RPC_CONCURRENCY (48) and the batch size the endpoint takes. A batch larger than the endpoint's per-second budget was refused forever before; now it shrinks until it fits. Test: SubgraphRpcAdaptiveConcurrency_test (an endpoint serving 4 at once, 429 past that, no batches: 64 calls answered in seconds with at most 128 refusals; before, the run didn't finish within 30 s). sushiswap v3 behind a 40 calls/s limit, 100 ms per request, 180 s: 429s 1,691 -> 236, HTTP requests 3,517 -> 2,081, same 544 events committed. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: read Makefile targets as render scripts moonwell's package.json has no scripts; its Makefile renders the manifest: `generate-config:` runs `YARN_SILENT=1 yarn mustache config/$(network).subgraph.json subgraph.mustache > subgraph.yaml && cp config/$(network).config.ts config/config.ts`, as `make generate-config network=base`. envio said "config.yaml not found". A package's Makefile targets are now scripts too (`make <target>`): recipe lines chained with `&&`, continuation lines joined, `$(var)` read as the variable make's command line sets, with the Makefile's own `var ?= x` as its default. Test: project_tests::renders_the_manifest_a_makefile_target_writes. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: load a workspace's own packages when nothing is installed, and never fetch them sushiswap's legacy subgraphs import `const` and `pricing`, packages of their own yarn workspace (packages/constants is named `const`, `main: index.ts`). Their install fails on graph-cli 0.21's vanished gluegun fork, so nothing links those packages into node_modules; the mapping failed to load, and the missing-package fetch asked the npm registry for `const`, which is someone else's package. The packages of the workspace the project is in (package.json `workspaces`, or pnpm-workspace.yaml) are now never fetched, and a bare import of one that Node can't find loads from its directory: package.json `main`, else `index.ts` or `assembly/index.ts`, and subpaths under it. Test: SubgraphWorkspacePackage_test.res (failed to load the mapping before, after a fetch from the registry). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: give a register pass to the handlers that create what a create checks The register pass reruns, at fetch time, only handlers whose code can reach DataSourceTemplate.create, against a store of what earlier passes saved. Heavy Helms' handleSkinVerificationUpdated creates a template only when the SkinCollection loaded by id exists, and handleSkinRegistered, which creates nothing, is the handler that saves it: the store never had it, the pass skipped the create, and the template's events were lost ("created the template ... but no register pass did"). The analysis (creates.rs) now also records, per top-level declaration, the entity types whose load decides a create in it (a create inside a branch or loop whose condition reads the loaded entity, after an if whose body returns or throws on it, or handed it as an argument) and the entity types it constructs (new E(...), store.set("E", ...)), outside codegen's schema module. Across all data sources, a handler that constructs one of the first kind gets a register pass. A handler that only updates such an entity doesn't: the one that created it had its pass, which keeps Uniswap's pool and crvUSD's Llamma handlers without one (0 extra passes on revert-univ3, crvusd, overlay, kiln; 1 on heavy-helms, 2 on flaunch). Test: SubgraphRegisterPassWriters_test.res, cargo test registers_the_writers_of_an_entity_a_create_depends_on, leaves_out_writers_when_the_create_does_not_depend_on_them. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: an ENVIO_SUBGRAPH_RPC of another chain than the registry's decides the chain 7876e8508 refused an endpoint whose eth_chainId wasn't the chain the registry gives the network's name. graph-node has no registry: it indexes a network on whatever chain the providers configured for it serve. Its docker-compose calls the one chain 'mainnet' whatever it is, so local subgraphs say 'network: mainnet' for an anvil node (31337), and Hedera's own graph-node says it for Hedera (hashgraph/hedera-the-graph's saucerswap v2). Those were refused; with an endpoint they now index the chain it serves, as graph-node does, and startup logs a notice naming both chains, so a mistyped endpoint is visible. An endpoint that doesn't answer leaves the name to the tables. Test: subgraph::project_tests::indexes_the_chain_the_rpc_serves_when_the_registry_names_another (replaces refuses_an_rpc_endpoint_of_another_chain). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: read an ABI from the npm package a failed install left out sushiswap's legacy exchange subgraph decodes with `../../node_modules/@sushiswap/core/build/abi/UniswapV2Factory.json`, a file of a package the workspace root installs, and that install fails on graph-cli 0.21's vanished gluegun fork. Translation stopped at "These ABI files the manifest names don't exist". iExec's PoCo does the same with node_modules/@iexec/poco. A manifest path through `node_modules/<package>/` that doesn't exist is now read from that package fetched into envio's cache (abi-packages/), at the version the nearest lockfile pins (npm, yarn, pnpm), else a package.json range, with npm and no lifecycle scripts; envio says so on stderr while it fetches, and the runtime warns once per file. Bundled codegen reads it the same way, and graph-cli's copy of the manifest names the fetched file. `path_case_fixes` becomes `path_fixes`: a fix is now a case match or a fetched file. Test: project_tests::reads_an_abi_from_the_package_a_failed_install_left_out (the cache already holds the package, so no network). sushiswap exchange with no install: fetches @sushiswap/core@1.4.2 from yarn.lock and gets past the ABIs to its next blocker (the workspace's own per-network constants package). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: name the script that writes a workspace package's missing entry sushiswap's `const` package names `main: index.ts` and gitignores it: its own `"prepare:mainnet": "mustache ../../config/mainnet.json index.template.ts > index.ts"` writes it, which the root runs for every package through `yarn workspaces run prepare:mainnet`. With nothing installed or prepared, the mapping failed with Node's "Cannot find package 'const'". The load error now says the package is the workspace's, which file is missing, and which of its scripts write it. envio doesn't run a workspace fan-out (`yarn workspaces run …`). Test: SubgraphWorkspacePackageEntry_test.res. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: compute a bit operation on an i64 in 64 bits An i64 is a bigint here, and JavaScript refuses &, |, ^, <<, >> and >>> between a bigint and a number ("Cannot mix BigInt and other types"), where AssemblyScript widens the i32 operand to i64. Kiln vSuite's SSZ encoding of a deposit amount, u32(amount & 0xffffffff), threw on every DepositEvent. Every bit operation and its compound assignment now goes through __envio_op (band, bor, bxor, shl, shr, ushr): two numbers keep JavaScript's int32 operation, an i32's; a bigint on either side computes in BigInt, the shift count taken mod 64, a left shift wrapped to 64 bits (an operand's sign telling an i64 from a u64), >>> as a u64 shift. Test: SubgraphInteger64Bitwise_test.res; cargo test expectations updated. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: write a generated ABI binding by its ABI name A mapping importing generated/<X>/<ABI>.ts for a data source no manifest of the project declares any more was compiled against a tree left from when one did: revert's uni-v3-staker imports generated/UniV3Staker/UniV3Staker after renaming its data sources UniV3Staker1.0.0 and UniV3Staker1.0.2, Mitosis' linea subgraph imports generated/ERC20/ERC20 from a renamed data source. `graph build` of the manifest fails on a clean checkout (asc TS6054); the deployed subgraph used the stale file. What graph codegen writes to <data source>/<ABI>.ts depends on the ABI alone (type-generator: one file per data source and ABI, from the ABI), so when no other manifest declares that data source, envio now writes the file from the first manifest ABI of that name (codegen::fill_from_abi_names), with a warning naming the ABI file. A name no manifest's ABI has still fails, with the reason (SubgraphGeneratedNotWritten now pins NNS's renamed IController). uni-v3-staker and Mitosis' linea subgraph now index unmodified. Test: SubgraphGeneratedFromAbiName_test.res, SubgraphGeneratedNotWritten_test.res Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: find missing generated files under a relative project root `envio start` in a project directory hands the runtime its root as ".", and when no mapping imports `schema`/`templates` (Kleros imports hand-split generated/PolicyRegistrySchema files) the generated directory stays at its "generated" default: both relative, while every import the scan resolves is absolute. No missing file was ever under the directory, so a tree the CLI had written without them counted as complete, and neither graph codegen nor the fill from other manifests ran. generatedDir now resolves its default, and missingGeneratedFiles and importsFrom resolve the directory they are given. The rung-1 helper always passes an absolute root, so the test calls the runtime's entry with the relative one the CLI passes. Test: SubgraphGeneratedDirRelative.test.ts Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: once and polling block handlers on templates graph-node gives a template instance its creation block as start block (chain/ethereum/src/data_source.rs match_and_decode): a `once` handler runs at that block and a `polling` one where `(block - start_block) % every == 0`, so every instance keeps a schedule of its own. The translator refused both on a template ("filtered block handlers on templates"); only unfiltered ones ran, per instance from its creation block. A template's block handler now visits every block from the chain's first static start, as the unfiltered one already did, and runs for each instance whose own schedule includes the block; the static data sources' register-mode `once` run no longer picks up a template's `once`. A `call` filter on a template stays refused (the trace source follows static addresses). OasisDEX/summer-earn-protocol (hosted set; ChainlinkProxy template with a `once` handler): unsupported-refusal before, synced now (447,719 events in its window). Tests: SubgraphTemplateFilteredBlockHandler_test.res; SubgraphValidation "refuses a call-filtered block handler on a template". Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * envio-tests: the filtered template block handler test uses a template of its own Template instances are kept in .envio/subgraph-template-instances.jsonl under the test process's cwd, keyed by chain and template, so two test files creating instances of a template named Feed on chain 1 saw each other's (SubgraphTemplateBlockHandler_test counted 5 ticks instead of 3). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * envio-tests: the Oracle template test names its own ABI file Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: pass over codegen steps that write no manifest beefy's `"codegen": "rm -Rf generated && graph codegen"`: with no manifest, envio ran `rm -Rf generated` as the steps that write it, then failed with "envio ran the codegen script's steps before `graph codegen` (rm -Rf generated), and they didn't write it" — instead of naming `configure` (./bin/prepare.sh), which does. Codegen steps that are only rm/mkdir/true aren't run as the manifest's writer, and steps that ran but wrote no manifest fall through to the missing-manifest error, which names the scripts that write it. Test: project_tests::passes_over_codegen_steps_that_write_no_manifest. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: ask the next IPFS gateway too when one keeps silent IPFS files (ipfs.cat, file data sources) were fetched from the gateways in order, each holding the file up for the whole request deadline (30 s) before the next was asked. On this box The Graph's gateway and Pinata sit silent on files they don't hold while ipfs.io answers 429, so each attempt at a missing file took a minute, and an ERC-8004 registry's first batch (agent0lab/subgraph, vvizardev/erc-8004-subgraph: file data sources for agent registration files) never committed within three minutes. A gateway now gets 2 s; past that the next one is asked as well (one that fails or lacks the file hands over at once, as before), the first to hand the file over answers and the rest are cancelled. A file is missing only when every gateway says so. graph-node asks the one IPFS node it is configured with; which gateway answers doesn't change the bytes. Test: SubgraphIpfsHedge_test.res (timed out at the 30 s deadline before). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * subgraph: name per-network scripts' networks by name, and run the network's sibling renders Seamless' leverage-tokens subgraph renders every network from one view: `"generate-manifest-base": "mustache ./networks.json ./templates/8453/subgraph.template.yaml > ./subgraph.yaml"`, the same for ethereum. Networks were named by the path component their views differ in; with one view both were "networks", and envio silently rendered the first. Its addresses come from a second script per network, `generate-addresses-base` (`… addresses.template.ts > ./src/constants/addresses.ts`), which the mappings import. Per-network scripts are now told apart by their names past the common prefix up to a `:` or `-` (`prepare:matic` → matic, `generate-manifest-base` → base), before falling back to the views. Once a network is picked, its other scripts that are standard renders run too and write their files; one that can't render is left to the user.

Test: subgraph::tests::refuses_an_rpc_endpoint_across_several_chains (an endpoint that answers 137).

After the codegen script's steps before `graph codegen` run, the manifest that step names (its first YAML argument, past --output-dir and --uncrashable-config values) is the one envio runs when subgraph.yaml isn't there; it is recorded as envio's, like a rendered one.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * effects: key a cache row by the input's sha256 when the input is over 2 kB An effect's cache table is keyed by its input, and a Postgres btree key takes at most 2704 bytes. A subgraph contract call with a large argument (curvefi/volume-subgraphs crvusd: AddMarket's call carries kB of calldata) made the whole batch write fail: `index row size 2856 exceeds btree version 4 maximum 2704 for index "envio_1_effect_envio_subgraph_eth_call_pkey"`. An input whose key is over 2,000 bytes is now keyed by "sha256:" + its sha256 hex; every shorter input keeps the key it always had, so existing cache rows stay valid. The row stores the output only, so nothing is lost. graph-node's call cache likewise keys by a hash of contract, calldata and block. Test: EffectCacheLongInput_test (a cached effect with a 6 kB incompressible input: the write was refused; now it is written and read back after a restart without calling the effect again). curvefi/volume-subgraphs crvusd on the harness: index/envio-bug (509 events, then the batch write error) -> ok (509 events, no error for 60 s).

main.envio dev/envio startwork inside an unmodified subgraph project —subgraph.yaml+schema.graphql+ AssemblyScript mappings +abis/, noconfig.yamland nothing envio-shaped in the tree. The CLI detectssubgraph.yaml, translates the manifest and schema into an envio config, and points the handler entry at a runtime that imports the mappings unchanged. Only@graphprotocol/graph-tsis shimmed; the project's own generated code — realgraph codegenoutput — executes as-is on top of it.Design and the compatibility matrix are in
docs/subgraph-compat.md.How it fits together
Translator (
packages/cli/src/subgraph/) — manifest and schema into an envio config, strict about what it accepts, reporting every finding at once rather than the first.network:resolves through a snapshot of The Graph's networks registry. Reachable without the filesystem throughfrom_subgraphfor tests. A template that shares a data source's name is folded into the same envio contract; the data source's handlers run for its own address and the template's for the addresses it creates, as on graph-node.AssemblyScript pass (
subgraph/assemblyscript.rs, in the addon, on the same oxc as the TypeScript handler loader) — rewrites the places where AssemblyScript and JavaScript mean different things before a mapping is imported:plus,div,equals,lt, …) when there is one, and integer/truncates;changetype<Class>;Each rewritten file carries an inline source map back to the mapping.
Runtime (
packages/envio/src/subgraph/, never exported) — each manifest handler becomes anindexer.onEvent/onBlock/contractRegisterwrapper.entity.save(),dataSource.address()) find their envio context throughAsyncLocalStorage.codegenscript has steps of its own aftergraph codegen, they run too.untilAnswered: a per-attempt deadline and exponential backoff on timeouts, network errors, 429/5xx and JSON-RPC rate limits, as graph-node does. Only a deterministic answer (a value, a revert, a definite miss) reaches the mapping. RPC reads are capped at 16 in flight, and a slot is held at most the deadline.BigDecimalreproduces graph-node's arithmetic digit for digit — 34 significant digits through thebigdecimal0.1.2 rounding graph-node pins — checked against 400 vectors that crate computes.Sync bridge (
UserContext.res,SyncWrites.res) — mappings are synchronous and envio's store is not. A read that misses memory suspends the handler, schedules the load and replays it; a round's writes are held until the round completes. Internal; no public API is committed to here.graph-ts shim — type-checked on every CI run against the real
@graphprotocol/graph-tsdeclarations, member by member, with each remaining gap recorded inconformance.ts.Changes to envio itself
[Boolean!]fields are supported (Postgres and ClickHouse).stateMutabilityis out of spec are read.GraphNetworksubenum is removed.Two pins the translator makes, not overridable
address_format: lowercase— graph-ts renders addresses lowercase, and id/derived-key parity depends on it.bytes_type: uint8array— graph-tsBytesis aUint8Array, so aBytescolumn stores the bytes rather than a hex rendering of them. Ids stay text, since envio ids are strings.Where it diverges from graph-node
@entity(immutable: true)is validated, then dropped — the write-once check is not enforced. Any subgraph that runs cleanly on graph-node never trips it.@derivedFromfield is emitted as[T!]!whatever nullability it was written with, including the one-to-one form. The lookup is the same either way, andgraph codegenreads it back as an array however it is declared.Query-API differences (Hasura vs graph-node GraphQL) are out of scope.
