It+closes a family of silent cross-host correctness bugs in the equality, ordering, integer-narrowing+and string primitives, and adds the systematic test coverage that exposed them. No kernel-surface+breaking changes.++### Highlights++- **Silent-wrong primitives corrected across hosts**+  ([#745](https://github.com/CategoricalData/hydra/issues/745),+  [#742](https://github.com/CategoricalData/hydra/issues/742)): new shared cross-host fixtures+  uncovered ~a dozen primitives (`equal`/`compare` on collections, float equality, `bigintToIntN`+  narrowing, `parseUint*` bounds, astral-plane string ops) that returned wrong results on one or more+  non-Haskell hosts while appearing to pass. All are now correct and verified per-host against the+  Haskell reference oracle.+- **Systematic test-coverage hardening**+  ([#749](https://github.com/CategoricalData/hydra/issues/749)): new kernel coverage for previously+  untested primitive behavior (equality/ordering collection depth, `notEqual`, `functions.const`/`flip`),+  which drove wiring those primitives into every host's default-implementation fallback.+- **Scale-preserving decimals across every lossy-double host**+  ([#727](https://github.com/CategoricalData/hydra/issues/727),+  [#719](https://github.com/CategoricalData/hydra/issues/719)): `Literal.decimal` gains a real+  scale-preserving representation (coefficient + scale) in the Scheme, Emacs Lisp, Common Lisp and+  TypeScript runtimes and coders, and the generated `Literal.Decimal` `equals`/`compareTo` on Java,+  Python and Scala stop ignoring scale. The `scaleDistinctTestNames` skip list — which had been+  masking the gap on five hosts — is deleted, so decimal scale is now verified everywhere rather+  than excused.++### Bug fixes++- **[#745](https://github.com/CategoricalData/hydra/issues/745)** silent-wrong equality/ordering,+  `bigintToIntN` narrowing, `parseUint32/64` bounds, and astral-plane `charAt`/`splitOn`/`compare`+  across the eight non-Haskell hosts.+- **[#742](https://github.com/CategoricalData/hydra/issues/742)** structural `equal`/`compare` on+  maps, sets and nested decimals no longer falls back to scale-blind or print-based comparison+  (including a hand-inlined Scala primitive that shadowed the overlay fix).+- **[#743](https://github.com/CategoricalData/hydra/issues/743)** kernel JSON decoder now rejects an+  `Either` object carrying both `left` and `right` keys instead of silently resolving one arm.+- **[#740](https://github.com/CategoricalData/hydra/issues/740)** the recursive parametric union decoder+  now emits an explicit type application instead of an untyped lambda, so recursive parametric-union+  types generate and compile on the Java host; also fixes `update-json-kernel` reconcile to build a+  complete inference universe so drifted kernel modules re-infer.+- **[#720](https://github.com/CategoricalData/hydra/issues/720)** Python's+  `hydra.lib.equality`/`ordering` did not satisfy IEEE `totalOrder` for floats, mis-ordering `NaN`+  and signed zero.+- **[#722](https://github.com/CategoricalData/hydra/issues/722)** two `kernelDefaultCoreProfile`+  correctness defects: rule ids that referred to rules no longer present, and a stubbed+  `isValidName` that accepted every name.++### Improvements++- **[#749](https://github.com/CategoricalData/hydra/issues/749)** `notEqual`/`const`/`flip` wired+  into each host's `#609` default-implementation fallback; orphaned Avro coder test suite recovered.+- **[#730](https://github.com/CategoricalData/hydra/issues/730)** a shared `~/.stack` build slot+  (`bin/with-stack-slot.sh`) replaces the pgrep slot mechanic, serializing concurrent GHC builds+  across the fleet behind a real mutex. The wrapper is now portable to macOS: `flock(1)` is+  util-linux and absent there, so it is emulated via Perl's `flock()` where missing, and the+  GNU-only `date -Is`/`date -d` calls are replaced with portable equivalents. Its bypass path also+  no longer re-execs forever. Without these, every entry point that routes through the slot —+  `bin/sync.sh`, `bin/test.sh`, `bin/run-bootstrapping-demo.sh` and `bin/prepare-release.sh` —+  failed immediately on macOS.+- **[#600](https://github.com/CategoricalData/hydra/issues/600)** the five published TypeScript+  packages are subpath-import-only (uniform export surface).+- **[#716](https://github.com/CategoricalData/hydra/issues/716)** `hydra.paths` reshaped onto the+  term-graph model (`TermGraph`/`TypeGraph`), aligning path steps with the term and type grammars+  and adding the link view of a graph; `mapKey`/`mapValue` collapse into a single `mapEntry` step.+- **[#701](https://github.com/CategoricalData/hydra/issues/701)** module cache freshness is now a+  Merkle hash over each module's dependency closure, so a change deep in the closure correctly+  invalidates dependents.+- **[#559](https://github.com/CategoricalData/hydra/issues/559)** host-agnostic build: the+  remaining hand-coded host build logic is promoted into `hydra.build.*`, with Java as the+  definitive second host.+- **[#721](https://github.com/CategoricalData/hydra/issues/721)** `checkNestedModuleNames` packaging+  check enforces the module-namespace no-prefix rule.++### Documentation++- **[#508](https://github.com/CategoricalData/hydra/issues/508)** de-Claude-speak documentation pass:+  style-guide section added, stale paths and dead links repaired, agent-operations wiki pages moved+  into `claude/`, and a `getting-started.md` guardrail against re-adding a TypeScript root export.+ ## [0.17.6] - 2026-08-30  Point release on the 0.17.x line, and the last backward-incompatible batch before the 1.0 surface
