Follow-up to the rip-recovery + drive-access updates: aligns the
remaining docs with the v0.13.6 single-shot read model and the
three-layer recovery architecture.
- architecture.md: module map says single-shot read; new paragraph on
layered recovery with postmortem pointer.
- api-design.md: EventKind enum example expanded; emission notes
document that BytesRead now fires from DiscStream::fill_extents and
Retry/SectorRecovered are no longer emitted in 0.13.6+.
- disc-to-rip.md: Step 10 of the pipeline diagram + module table
reflect single-shot read.
- docs/README.md: added rip-recovery.md to the TOC.
Updates docs/ to reflect the recovery-loop strip:
- rip-recovery.md: drops Phase 1/2/3 description, replaces with three-layer
model (Disc::patch multi-pass / DiscStream batch halving / Drive::read
single-shot). Notes that no SCSI resets fire from any retry path.
- drive-access.md: removes SG_SCSI_RESET + STOP/START UNIT escalation
references; SgIoTransport::reset is now kernel SG_IO flush + ALLOW
MEDIUM REMOVAL only.
- src/mux/disc.rs + tests/: cargo fmt cleanup.
- README quick-start gains a multi-pass example using the new
Disc::copy + Disc::patch primitives.
- New docs/rip-recovery.md documents the two-stage rip model: mapfile
format (ddrescue-compatible), CopyOptions/PatchOptions surface, the
pass-1/pass-2 algorithm, and the design decisions (why no MODE
SELECT, why ISO intermediate, why ddrescue mapfile).
No code change.
Architecture:
- One stream per format, bidirectional PES (read/write on same type)
- IsoStream merged into DiscStream (one type, any SectorReader)
- Disc::copy() for disc→ISO raw sector dump
- IOStream trait deleted, all byte-level Read/Write removed
- ContentReader/OpenDisc/open_title/open_input/open_output deleted
- CountingStream wrapper for progress tracking
Error codes:
- All io::Error English strings replaced with Error enum variants
- From<Error> for io::Error conversion
- Unused variants removed, new stream/mux variants added
Deleted: mkvout.rs, pesout.rs, isowriter.rs, mkv-muxer-plan.md
Updated: all docs, README stream table, CHANGELOG
238 tests, 0 clippy warnings.
- Error codes as public constants (E_DEVICE_NOT_FOUND etc.) — single source of truth
- SCSI opcodes as named constants (SCSI_READ_10, SCSI_REPORT_KEY, etc.)
- AACS key class constant, MKB format constant
- No magic numbers in CDB construction
- docs/disc-to-rip.md — end-to-end flow from disc insert to decrypted content
- Links all module docs together as a starting point
