repo-pre-2 Capability Record

Status Vocabulary

This document separates inherited pre1 claims from fresh pre2 validation:

INHERITED CLAIM: documented by the unchanged pre1 snapshot; not re-tested for pre2.
STATIC GATE: visible in tracked source or build declarations; runtime behavior was not exercised.
NOT IMPLEMENTED: explicitly excluded by inherited project documentation.
NOT CLAIMED: inherited documentation deliberately limits the support claim.
NOT RUN: no build or runtime validation was performed for repo-pre-2.

INHERITED CLAIM is provenance, not a new PASS result. Existing reports under tests/results/manual/ describe earlier pre1 work and must not be cited as a fresh repo-pre-2 execution.

Snapshot Evidence

repo-pre-1 source tree:   6a5a1a49d4a4e08f6ef1155de240500e63a15365
repo-pre-2 initial tree:  6a5a1a49d4a4e08f6ef1155de240500e63a15365
src-linux reference tree: b79b9a8b62f633e887a8b99075ff9412fabd7f83
runtime validation:      NOT RUN

The inherited claims below are transcribed at category level from README.md and docs/features.md. They are not an independent feature review.

Capability Matrix

Area	Inherited pre1 claim or static declaration	Pre2 status
Mount and metadata	Read-only mount/unmount, `statfs`, superblock checksum and bounds, compact/extended inodes, 48-bit fields	INHERITED CLAIM; NOT RUN
Plain data	Flat plain, flat inline, tail bounds, and logical block accounting	INHERITED CLAIM; NOT RUN
Chunk and devices	Chunk indexes, holes, device tables, explicit devices, and flatdev mapping	INHERITED CLAIM; NOT RUN
Compressed data	LZ4, MicroLZMA, DEFLATE, full/compact indexes, partial references, HEAD2, ztailpacking, and qualified fragment forms	INHERITED CLAIM; NOT RUN
ZSTD	Source is always listed; `WITH_ZSTDIO=1` adds `ZSTDIO`, while the default is `0`	STATIC GATE; runtime NOT RUN
Directories and vnode operations	Lookup, readdir, cookies, namecache, access, readlink, pathconf, pager integration, and read-only mutation rejection	INHERITED CLAIM; NOT RUN
Xattrs and ACLs	Inline/shared namespaces, metabox storage, long/packed prefixes, and POSIX ACL reads	INHERITED CLAIM; NOT RUN
NFS export	64-bit NIDs, generation handling, and malformed/stale handle validation	INHERITED CLAIM; NOT RUN
Build target	`src/Makefile` rejects architectures other than `amd64`	STATIC GATE; build NOT RUN
Write support	Writable filesystem operations	NOT IMPLEMENTED
`VOP_BMAP`	Explicitly unsupported in inherited documentation	NOT IMPLEMENTED
Complete future-format parity	All future incompat features and every dedupe encoding	NOT CLAIMED
Explicit compressed-extent positive payload	Inherited documentation records only partial coverage	NOT CLAIMED; NOT RUN
Performance guarantees	Manual observations are not a performance contract	NOT CLAIMED

Interpretation Rules

Source presence, feature-bit definitions, or build selection do not prove a runtime capability.
A pre1 manual report does not become a pre2 PASS merely because the initial trees match.
Phase 1 mechanical edits must not expand or reduce this capability matrix.
A future status change requires recorded evidence from an actually executed validation step.

Current Validation Declaration

No build, QEMU execution, test script, smoke test, mount, malformed-image probe, or performance measurement was run for this initialization. The current repo-pre-2 runtime validation result is therefore NOT RUN in every category.
