CellScript 0.16.2

CellScript 0.16.2 is a builder-ergonomics patch for CKB resource identity
handoff. It keeps the 0.16 compiler/runtime scope, while making external
transaction builders less dependent on copied harness conventions.

Highlights

• cellc resource-identity emits a compiler-owned passive resource identity
  artifact and JSON plan for resource output type scripts.
• cellc validate-tx --resource-identities checks created resource outputs
  against the generated passive identity plan.
• cellc validate-tx --production rejects known fixture-only resource
  identities, including devnet always_success and all-zero placeholders, when
  they appear as real resource output type scripts.
• cellc explain-assumptions and cellc solve-tx can be scoped with
  --entry-action or --entry-lock, so external builders can consume the
  selected entrypoint contract instead of whole-module noise.
• Builder-facing contract commands now emit JSON by default; --json remains
  accepted for compatibility, and --human prints a short terminal summary.
• cellc builder manifest and cellc builder check are canonical namespace
  forms; builder-manifest and builder-check remain aliases.
• cellc entry-witness now exposes raw script-group witness placement in its
  default JSON output.
• cellc solve-tx now exposes submit_ready: false, missing builder
  steps, structural builder-evidence requirements, a fillable evidence
  template, and a fixture identity policy.
• cellc builder manifest and cellc builder check provide a two-step
  builder-facing workflow over the lower-level ABI, constraints, witness,
  assumption, resource identity, and validation commands.
• Builder docs clarify that scoped action artifacts are active verifiers and
  must not be used as passive MintAuthority, Token, Pool, or LPReceipt
  resource identities.

Validation

The release patch was validated with the v0.16 CLI/backend suite:

cargo test --test v0_16 -- --nocapture

The suite covers resource identity plan generation and validation, scoped
assumption/solver output, wildcard structural evidence requirements, entry
witness placement, builder manifest/check flow, active artifact misuse
rejection, and production fixture-identity rejection.

The wiki and builder-facing examples were audited so contract commands use the
default JSON output and the canonical cellc builder manifest /
cellc builder check namespace. The old dashed forms and --json flag remain
accepted for compatibility.

The builder UX was also smoke-tested against
WuodOdhis/cellscript-swap-builder main at
479feb004338524d367b6656c6fb356ca7918f28: the external Rust builder accepted
compiler-generated entry witness bytes and passive Token:token_out resource
identity, cellc builder check --production --primitive-strict 0.16 passed the
positive transaction shape, and negative checks rejected both scoped action
artifact and always_success fixture identities for the created token output.
