+### Added
+- Recover backlog material from deleted `docs/archive/` into the `req/`
+  catalog as `Draft`/`Could`/`Recovered` entries: encryption/compression
+  (`fr-036`, `fr-037`, `feat-011`, `qa-sec-001`, `asm-007`), transactions
+  (`fr-038`, `feat-012`), garbage collection (`fr-039`, `feat-013`),
+  shared-memory backend (`fr-040`, `feat-014`, `if-013`), and the
+  byte-offset conversion public API (`fr-035`, `if-012`, `ac-013`).
+- New code anchor `pmm-detail-persistmemorytypedapi-pptr_from_byte_offset`
+  in `include/pmm/typed_manager_api.h` and an extended `req:` list on
+  `pmm-pptr-byte_offset` in `include/pmm/pptr.h` for the recovered
+  byte-offset API.
+- `req:` traceability block on `tests/test_issue211_byte_offset.cpp` and
+  `@see req/...` lines on six other tests to back-link verification to
+  the catalog.
+- Explicit `Won't`/`Deprecated` entry `feat-015` recording that the
+  detailed visual demo specification from `docs/archive/demo.md`
+  (memory-map view, metrics view, structure tree, scenario manager,
+  FPS/memory constraints) is intentionally out of PMM scope; the
+  optional demo-target and its build dependency remain represented via
+  `if-011` and `dep-002`.
+- Feature-level trace entries for `feat-011…feat-015` and a recovered
+  byte-offset API block in `req/13_traceability_matrix.md` so the new
+  requirements are surfaced in the matrix.
+
+### Fixed
+- Strengthen the per-block encryption policy in `fr-036` / `qa-sec-001`:
+  require a unique nonce per encryption via `block_generation_counter`
+  (recovered from the original `docs/archive/phase7_4_encryption_compression.md`
+  proposal) and require authenticated encryption (AEAD AES-256-GCM, or
+  AES-256-CTR with HMAC) so wrong-key / tampered-ciphertext / replayed-nonce
+  load attempts are rejected through `PmmError::AuthenticationFailed`.
+  Closes the CTR-mode IV-reuse gap raised in PR review.
+
+### Changed
+- Bump `scripts/source-loc-baseline.txt` 6352 → 6356 to absorb the new
+  doc-only anchor lines in the regenerated single-header. Production
+  code is unchanged.
+- Regenerate `single_include/pmm/pmm.h` to incorporate the new anchor
+  metadata.
+- Refresh README badge (release-owned) to match `CMakeLists.txt`
+  `6.2.1`; the docs-archive cleanup unavoidably touches `README.md`,
+  so the version-consistency check is no longer skipped.
+
+### Removed
+- Delete `docs/archive/` (12 historical phase plans / target-model and
+  backlog sketches, ~3 000 lines). Each file was audited; valuable
+  material moved into `req/` (see Added) or recorded as out-of-scope
+  in the PR body. References from `README.md`, `docs/index.md`,
+  `docs/repository_shape.md`, and `docs/deletion_policy.md` are
+  updated accordingly.
