existing tf-config tests = 276 total, all passing +- 0 clippy warnings, 0 regressions across tf-config and tf-security +- ✅ Resolved review finding [HIGH]: Fixed TOCTOU race condition — removed

2.7 spec +- ✅ Resolved review finding [HIGH]: Corrected File List line count from "307 lines" to "805 lines" +- ✅ Resolved review finding [MEDIUM]: Documented `load_all()` fail-fast semantics in docstring +- ✅ Resolved review finding [MEDIUM]: Made `TemplateKind::all()` public for external consumers +- ✅ Resolved review finding [MEDIUM]: Added `no_run` doc-tests for `TemplateLoader::new()` and `load_template()` +- ✅ Resolved review finding [MEDIUM]: Added `Serialize`/`Deserialize` derives on `TemplateKind` +- ✅ Resolved review finding [LOW]: `Serialize` on `TemplateKind` covered by MEDIUM item above +- ✅ Resolved review finding [LOW]: Added `//! # Usage` section with code snippet in module doc +- ✅ Resolved review finding [LOW]: Documented `MIN_PPTX_SIZE = 100` rationale in doc comment +- ✅ Resolved R2 review finding [MEDIUM]: Changed `TemplateLoader` to borrow `&'a TemplatesConfig` instead of cloning — eliminates unnecessary copy +- ✅ Resolved R2 review finding [MEDIUM]: Refactored `load_all()` to use single `resolve_path()` method — eliminates duplicated `is_configured()` + `get_configured_path()` resolution +- ✅ Resolved R2 review finding [MEDIUM]: `content_as_str()` now returns PPTX-specific hint "use content() for raw bytes instead" for binary templates +- ✅ Resolved R2 review finding [LOW]: Removed redundant `size_bytes` field from `LoadedTemplate` struct — now computed on-the-fly from `content.len()` +- ✅ Resolved R2 review finding [LOW]: Added boundary tests for `MIN_PPTX_SIZE` at exactly `MIN_PPTX_SIZE - 1` (reject) and `MIN_PPTX_SIZE` (accept) +- ✅ Resolved R2 review finding [LOW]: Made `TemplateKind::expected_extension()` public for external consumers +- ✅ Resolved R3 review finding [MEDIUM]: `validate_extension()` now uses `eq_ignore_ascii_case()` for case-insensitive extension comparison — `.MD`, `.Md`, `.PPTX` are accepted +- ✅ Resolved R3 review finding [MEDIUM]: `validate_extension()` no longer allocates `String` on happy path — compares raw extension without dot prefix +- ✅ Resolved R3 review finding [LOW]: Added `#[derive(Debug)]` on `TemplateLoader` for consistency with other public types +- ✅ Resolved R3 review finding [LOW]: `load_all()` now uses `HashMap::with_capacity(TemplateKind::all().len())` instead of `HashMap::new()` +- ✅ Resolved R3 review finding [LOW]: Added directory-as-path edge case test and context-aware `ReadError` hint ("path is a directory" vs "check permissions") +- ✅ Resolved R4 review finding [MEDIUM]: Added `#[serde(rename_all = "lowercase")]` on `TemplateKind` — serde now produces "cr", "ppt", "anomaly" matching `Display` output +- ✅ Resolved R4 review finding [MEDIUM]: Added max file size guard via `fs::metadata().len()` pre-check (10MB for .md, 100MB for .pptx) before `fs::read()` — prevents unbounded memory allocation +- ✅ Resolved R4 review finding [MEDIUM]: Moved `tempfile` to workspace dependency pattern (`tempfile.workspace = true`) — consistent with `serde`, `thiserror`, `assert_matches` +- ✅ Resolved R4 review finding [LOW]: Changed `validate_format` public API from `path: &str` to `path: &Path` — follows Rust path conventions +- ✅ Resolved R4 review finding [LOW]: Changed `MIN_PPTX_SIZE` from `u64` to `usize` — eliminates all `as usize` / `as u64` casts +- ✅ Resolved R5 review finding [MEDIUM]: Added post-read `content.len()` size check after `fs::read()` — guards against TOCTOU where file grows between `fs::metadata()` and `fs::read()`, or when metadata was unavailable +- ✅ Resolved R5 review finding [MEDIUM]: Clarified `validate_format` docstring — `path` parameter documented as "used only for error context, not validated or resolved" +- ✅ Resolved R5 review finding [LOW]: Whitespace-only markdown templates now rejected — `validate_markdown` checks `text.trim().is_empty()` after UTF-8 validation +- ✅ Resolved R5 review finding [LOW]: Added detailed rationale documentation for `MAX_MD_SIZE` (10 MB) and `MAX_PPTX_SIZE` (100 MB) constants +- ✅ Resolved R5 review finding [LOW]: Added `#[cfg(test)] LoadedTemplate::new_for_test()` constructor for downstream test consumers +- ✅ Resolved R6 review finding

parameter instead of hardcoding `"ppt".to_string()` +- ✅ Resolved R6 review finding [MEDIUM]: Extracted `oversized_error()` helper to eliminate duplicated size-check error construction between pre-read and post-read guards +- ✅ Resolved R6 review finding [MEDIUM]: Changed `TemplateError` variants from `kind: String` to `kind: TemplateKind` — enables type-safe programmatic matching on template kind in error handlers +- ✅ Resolved R6 review finding [LOW]: `validate_extension` now extracts `path.extension()` to single binding — avoids duplicate call +- ✅ Resolved R6 review finding [LOW]: Changed `LoadedTemplate::new_for_test()` from `#[cfg(test)]` to `#[cfg(any(test, feature = "test-utils"))]` — available to downstream crates via `test-utils` feature flag +- ✅ Resolved R6 review finding [LOW]: Added `BinaryContent` variant to `TemplateError` — `content_as_str()` now returns semantically correct error for binary templates +- ✅ Resolved R6 review finding [LOW]: File List corrected — `serde_json = "1.0"` already present in workspace `Cargo.toml` (line 26) +- ✅ Resolved R6 review finding [LOW]: Added `Clone` derive on `TemplateError` — all fields are trivially cloneable (`String` and `TemplateKind`) +- ✅ Resolved R7 review finding [MEDIUM]: `test_load_all_fails_on_invalid_template` now verifies `TemplateError::FileNotFound` instead of just `is_err()` — detects behavior regressions +- ✅ Resolved R7 review finding [MEDIUM]: `InvalidExtension` error now displays `"(none)"` instead of empty string `""` for files without any extension +- ✅ Resolved R7 review finding [MEDIUM]: `oversized_error` hint no longer includes redundant path — simplified to "Reduce the file size or verify this is a valid {kind} template" +- ✅ Resolved R7 review finding [LOW]: Added `PartialEq` derive on `TemplateError` — enables `assert_eq!` in tests and improves downstream ergonomics +- ✅ Resolved R7 review finding [LOW]: Added `Cargo.lock` to File List documentation +- ✅ Resolved R7 review finding [LOW]: Added test for file without any extension — covers `"path/to/README"` edge case, verifies `actual` field shows `"(none)"` +- ✅ Resolved R8 review finding [MEDIUM]: Deduplicated extension validation — replaced `config.rs:has_valid_extension()` with `has_valid_template_extension()` that delegates to `TemplateKind::expected_extension()` as single source of truth +- ✅ Resolved R8 review finding [MEDIUM]: Documented relative path limitation — added known limitation note to `load_from_path()` and `load_template()` docstrings +- ✅ Resolved R8 review finding [MEDIUM]: Documented `load_all()` iteration order (`Cr`, `Ppt`, `Anomaly`) in docstring +- ✅ Resolved R8 review finding [LOW]: `content_as_str()` now returns `InvalidFormat` with "invalid UTF-8" cause for non-UTF-8 markdown templates, reserves `BinaryContent` for PPTX only +- ✅ Resolved R8 review finding [LOW]: Clarified test count — 297 tests pass via `cargo test` result lines (canonical method: sum of "N passed" across all test runners) +- ✅ Resolved R8 review finding [LOW]: Renamed `validate_format` to `validate_content` for clarity — function validates bytes, not file-level format +- ✅ Resolved R9 review finding [HIGH]: `validate_pptx` now enforces presence of OOXML entry marker `[Content_Types].xml` in addition to ZIP magic and minimum size; added failing-then-passing regression test `test_validate_pptx_missing_content_types_rejected` +- ✅ Resolved R9 review finding [HIGH]: Restored review traceability by recording reviewed baseline SHA in Dev Agent Record (`d4010f70c0e7b1a5947f7240181dcaec78dabe23`) and refreshing File List entries for modified files +- ✅ Resolved R9 review finding [MEDIUM]: Reused tf-config redaction guard for template error paths via `sanitize_path_for_error()` + `config::redact_url_sensitive_params`; added regression test `test_error_paths_redact_sensitive_url_query_params` +- ✅ Resolved R9 review finding [MEDIUM]: Aligned story
