Fixed a latent `#include ` omission in + small_vector.hpp found in the process. +- **JsonValue accessors unified to snake_case** (`as_string`/`as_number`/… + + `to_string`) to match YamlValue and the project convention; added + `JsonValue(int)`/`JsonValue(const char*)` to remove ctor ambiguities. +- **Dependency audit**: removed the inverted `concurrent_map → atom/search` + dependency (embedded a self-contained LRU); rtype↔meta reflection confirmed + NOT duplication (different serialization backends: self-built rjson/ryaml vs + vendored nlohmann/yaml-cpp). +- **Learned from the canonical reference (C++23 `std::expected`)**: audited + `expected`'s monadic surface against the standard and closed the gaps — + added `error_or(G&&)` (error-channel analogue of `value_or`, previously + missing) and `transform()` (the std-canonical name for the value-mapping + op `map`, for std-interface parity). Robin-hood map, the LRU caches, and the + RAII/condition-variable concurrency fixes likewise follow established + best-practice patterns. + +### 2026-06-15 + +- Namespace normalization: every header's types moved into `namespace atom::type` + (previously several were global-scope, bare `atom`, or misplaced in + `atom::containers`/`atom::utils`); cross-module consumers updated, no compat + aliases. Header guards standardized to `ATOM_TYPE__HPP`. +- Modernization: added `operator<=>`/`operator==`, `std::formatter`, and + `[[nodiscard]]` to containers/wrappers; integrated `atom::error` exceptions; + reused `atom::meta` concepts where applicable. +- Fixed numerous pre-existing bugs surfaced by wiring previously-orphaned tests + (small_vector/small_list/flatset/static_vector/concurrent_vector/optional/ + indestructible/no_offset_ptr/cstream/args), including crashes (infinite + recursion, null deref, iterator invalidation, empty-container UB) and + exception-safety issues.
