…NG-631)
`add_version` took `(DeployMode, code)` — two parameters encoding one decision,
admitting a combination that means nothing (`Normal` alongside bytes already
published globally) and offering no way to point a version key at a global
contract already on chain. A second registry serving the same code therefore
paid the global-contract storage stake a second time: 65+ NEAR for the
universal-account wasm, to publish bytes the protocol already stores under that
exact hash.
Fold the pair into one source:
VersionSource::Stored(code) = 0
VersionSource::PublishGlobal(code) = 1
VersionSource::ExistingGlobal(hash) = 2
Discriminants 0 and 1 match `DeployMode::Normal`/`GlobalHash`, and `Base64VecU8`
is a transparent borsh newtype over `Vec<u8>`, so the encoding is byte-identical
for both existing modes and the 1.1.0+ registries already deployed keep working
untouched. That equality is pinned by a golden-bytes test rather than trusted,
and the `live_release_migrates_onto_current` cases exercise the 0.1.0, 1.0.0 and
1.1.0 registries end to end. Pre-1.1.0 predates the tag entirely and still takes
a bare `(version_key, code)`; a code hash has no representation there at all, so
that combination is an error rather than an encoding the registry would misread
as a wasm blob.
The hash is verified, not trusted. `ExistingGlobal` inserts the entry, then a
create/`use_global_contract`/delete receipt on `probe.<registry>` proves a global
contract stands behind it; a hash with nothing behind it fails the receipt and
the existing `add_version_01_finalize` frees the key again. This is what makes an
unverified typo unreachable — `remove_version` hard-panics on a `GlobalHash`
entry, so a burned key would stay burned. The probe uses a name distinct from
`deploy.<registry>` so it cannot collide with an in-flight publish, and both
paths now share one scratch-account helper.
The probe takes one yoctoNEAR, measured rather than estimated. The account is
created and deleted inside a single receipt, so it never has to satisfy a
storage-staking minimum, and `use_global_contract` copies no code to stake for;
sandbox confirms the receipt succeeds at 1 yocto, against ~50 NEAR to publish the
same market wasm. The cost here is gas.
`DeployMode` remains for `registry.addArtifactVersion`, where the bytes are
resolved from the catalog and only store-versus-publish is open.
The gateway cannot yet reject `ExistingGlobal` against a registry too old to
parse it: that check keys on the version number of the release carrying this
change, which does not exist until it ships. Such a registry fails on chain
rather than at preflight until then; the preflight check follows in a stacked
change once this is released.

unsupported-source match to remove the claim that pre-1.1.0 registries reject
ExistingGlobal only on chain; state that
RegistryVersion::encode_add_version_args already performs this validation during
plan generation, while preserving the comment’s remaining rationale.
In `@service/relayer/tests/relayer.rs`:
- Around line 486-493: Update the comment above the version-registration calls
to refer to VersionSource::Stored and VersionSource::PublishGlobal instead of

Make the scratch account id unique per call.
scratch_account derives a deterministic id from a constant prefix, so every PublishGlobal call uses deploy.<registry> and every ExistingGlobal call uses probe.<registry>. The doc comment only separates publish from probe. It does not separate two publishes or two probes.
If the owner submits two add_version calls of the same variant close together, the receipts can interleave. The second create_account then fails because the account already exists, or one batch's delete_account removes the account the other batch is still using. add_version_01_finalize rolls the version key back, so the result is a spurious failure rather than corrupt state, but the failure is confusing and hard to reproduce.
Derive the prefix from the request instead. The version_key is unique by the require! above, so its hash is a sufficient discriminator.
🔒 Proposed fix: per-request scratch account id
- /// `prefix` separates the publish and probe accounts so a probe cannot land on an in-flight
- /// publish.
- fn scratch_account(prefix: &str) -> Promise {
- let account_id: AccountId = format!("{prefix}.{}", env::current_account_id())
+ /// `prefix` separates the publish and probe accounts so a probe cannot land on an in-flight
+ /// publish. `version_key` separates two calls of the same kind, which are otherwise able to
+ /// interleave onto one account id.
+ fn scratch_account(prefix: &str, version_key: &str) -> Promise {
+ let discriminator = hex::encode(&env::sha256_array(version_key.as_bytes())[..8]);
+ let account_id: AccountId = format!("{prefix}-{discriminator}.{}", env::current_account_id())
.parse()Then pass &version_key at both call sites.

Not taking this one, deliberately.
The collision is real, but two of its three parts predate this PR and the third is bounded. deploy.<registry> has been a fixed id since 1.1.0 — this PR does not touch that derivation, only adds a second prefix beside it. add_version is owner-only, so hitting it means the owner racing two of their own calls into overlapping receipts. And as you note, add_version_01_finalize frees the version key, so the outcome is a spurious failure with clean state rather than corruption.
Against that, the proposed fix changes the account id on the existing publish path inside a PR that is already a breaking registry change, and probe-<16 hex>.<registry> spends 22 characters of a 64-character account id — fine for registry.templar.near, tighter for longer testnet ids.
Worth doing on its own, where it can cover both prefixes and be tested for the interleaving directly, rather than folded in here. I have not filed anything for it yet — flagging for @peer2 to decide.
The PR description overstates the guarantee, though; it says the probe prefix means it "cannot collide with an in-flight publish", which is true of probe-versus-publish and silent on probe-versus-probe. I will tighten that wording.
…ry-register-an-existing-global-contract-by-code-hash
Review feedback on #596. `1 NEAR / 10_000 * len` was spelled out at four sites across three test files, so a change to the publish rate needed four coordinated edits and a missed one would surface only as an underfunded call in the sandbox. It now lives once as `templar_gateway_testing::publish_deposit_for`. Also corrects two comments the `VersionSource` fold left behind: the relayer test still named `Normal`/`GlobalHash`, and the client's compatibility note claimed every too-old registry fails on chain, when pre-1.1.0 has no encoding for a code hash and `encode_add_version_args` rejects it at plan time.

DeployMode::Normal/GlobalHash, andBase64VecU8is a transparent borsh newtype overVec<u8>, so the encoding is byte-identical for both existing modes — the 1.1.0+ registries already deployed keep working untouched.That equality is pinned, not trusted:
borsh_is_wire_compatible_with_deploy_modeasserts it directly against the old tuples, and the threelive_release_migrates_onto_currentsandbox cases drive real 0.1.0/1.0.0/1.1.0 registries end to end. Pre-1.1.0 predates the tag entirely and still takes a bare(version_key, code); a code hash has no representation there at all, so that combination errors rather than encoding into something the registry would misread as a wasm blob.The hash is verified, not trusted
ExistingGlobalinserts the entry, then a create/use_global_contract/delete receipt onprobe.<registry>proves a global contract stands behind it. A hash with nothing behind it fails the receipt and the existingadd_version_01_finalizefrees the key again.This is what makes an unverified typo unreachable:
remove_versionhard-panics on aGlobalHashentry, so without the probe one bad hash would burn a version key permanently. The probe uses a name distinct fromdeploy.<registry>, so it cannot land on an in-flight publish; both paths now share one scratch-account helper. Each prefix is still a single fixed id, so two probes can collide with each other exactly as two publishes could before this change — an owner-only race that rolls back cleanly, raised in review and left for its own change.The probe costs one yoctoNEAR — measured, not estimated
The issue anticipated measuring an account-creation floor and requiring a deposit covering it. Measured in sandbox, the floor is 1 yocto: the probe account is created and deleted inside a single receipt, so it never has to satisfy a storage-staking minimum, and
use_global_contractcopies no code to stake for. The cost is gas.I built the constant first, then deleted it once the measurement came back — a deposit the chain does not require would have been invented machinery.
assert_one_yocto()is the contract's existing idiom for exactly this. Against ~50 NEAR to publish the same market wasm, the ratio assertion indeployment.rsis now> 1_000_000x.Two deliberate deviations
registry.addArtifactVersionkeepsDeployMode. The issue saysDeployModeretires from "the gateway spec"; I read that as scoped toregistry::AddVersion, where the invalid combination lived. The artifacts path resolves its own catalog-verified bytes, soExistingGlobalis meaningless there and only store-versus-publish is open. Say the word if you meant a full retirement.No preflight version gate yet, and no version bump. Rejecting
ExistingGlobalagainst a registry too old to parse it keys on the version number of the release carrying this change — which does not exist until it ships. Such a registry fails on chain rather than at preflight until then. The check is prepared and stacked: branch 2, to merge only after this is released.Acceptance criteria

The three-variant gateway test reads its hash through a raw
get_version_code_hashview rather thanregistry.getVersion, because the pre-existing ENG-559/560 gate putsgetVersionbehind ≥1.3.0 — which no deployed or sandbox registry satisfies yet. Worth a separate look: that gate makes severalregistry.*reads unusable against every registry currently in existence.🤖 Generated with Claude Code
