-# Configuration integration audit
-
-The audit fixes concrete failures in the original release:
-
-- Numeric conversion truncated fractions, accepted float values outside integer
-  range, rejected ordinary `uint` input, and could not decode full `uint64`.
-  Checked conversions now operate in the source integer domain and reject loss.
-- Parser integers depended on 64-bit `int`. They are now explicitly `int64`;
-  narrowed destinations retain overflow checks on every architecture.
-- Failed decoding could partially overwrite a destination; decoding now commits
-  only after success. Named string map keys no longer panic, and tags with an
-  empty name correctly fall back to the field name. Existing pointer defaults
-  survive updates, and errors do not mutate the original pointee or containers.
-- Fixed arrays could be encoded but not decoded. They now decode with exact
-  length and element-range checks, including nested arrays and arrays of tables.
-- Nested table headers failed to quote their component keys. Arrays of interface
-  table values could encode empty tables. Mixed/nested arrays now encode using
-  inline tables, and nested keys use the same escaping as scalar keys.
-- Backspace/form-feed strings did not decode the escapes emitted by Marshal.
-  Invalid UTF-8, raw string controls, missing array/inline-table commas and
-  missing statement separators are rejected.
-- Cyclic encoding could overflow the stack. Encoding/decoding and dotted paths
-  now have depth limits. Numeric keys and unsupported uint64 literals fail
-  explicitly instead of generating unreadable output. Nil array elements error.
-- Numeric key checks now cover decimal keys of any length, including values
-  beyond int64; the parser and encoder apply the same restriction.
-- Formatting an invalid unsigned input could recurse through a cyclic map.
-  Conversion errors now report the source type without formatting its contents.
-- Map decoding and encoder entry collection preallocate from known sizes. All
-  operation state stays local; no global cache or lock was added.
-
-No datetime, custom marshal interface, literal-string or multiline-string
-feature was added. The supported subset and remaining deviations are in README.
-
-This branch consolidates the prior `audit/numeric-hardening-20260928` and
-`audit/config-roundtrip-hardening` commits, retaining both in its ancestry.
-Only this repository is changed. Consumer migration, watcher publication and
-snapshot ownership remain work for the separate config audit.
-
-Verification for this pass: unit and race suites and `go vet` pass on Go 1.27.1;
-the 386 test binary cross-compiles. This host cannot execute 386 binaries, so CI
-executes that suite. The first CI run caught a test fixture that cast an int64
-through machine-sized int before Decode; that fixture now retains its int64.
-Regression tests for fixed arrays, pointer defaults and oversized numeric keys
-were also run against recovered commit `6384895` and reproduced the failures.
-
-The 15-second round-trip fuzz run passed 71,221 executions. Its property now
-fails on unexpected Marshal errors instead of silently skipping them; only the
-documented whole-tree depth bound is excluded. Integer fuzzing covers full
-uint64 preservation, signed boundaries and uint8 narrowing. CI runs these bounded
-fuzz checks on every push and pull request. Refer to the PR checks for final CI
-results.
-
-Integration limits: parsed integers are int64; raw assertions must migrate.
-Direct Decode can retain the full uint64 range, but file encoding rejects values
-above MaxInt64. Interface destinations retain source references, so config must
-own its snapshots. Comment text can be collected with the existing lexer and
-written as a preamble; Marshal does not preserve source positions. README
-documents these contracts and the intentionally limited TOML syntax.
