Merge h9-fuzzcov: every fuzz target now guards its own reach
Only two targets asserted that their generator still reaches the interesting outcomes; the other 25 could rot to instant-rejection and pass every no-crash check while testing nothing. Six targets that split into distinct outcomes now carry a reached-outcomes floor above a measured minimum round count -- decode-bounded, target-size, predicates, adversarial sync parsers, logstore open, and unframe each must reach both their accept and reject arms, or the run fails. Thresholds are measured at a fixed seed and re-checked at a second, and each floor is proven to trip when the generator is biased to one arm. Single-outcome round-trip targets carry a one-line exemption instead of a vacuous assert. The measurement also named several generators that under-reach their target's arms; those are recorded for follow-up, not fixed here. check-in: 57d8994848 user: dmestas tags: trunk | |

Merge h5b-verbasserts: TigerStyle asserts on the cmd verb layer
The companion to the library assert pass, now on the two split verb files. Eighteen asserts stating invariants that already hold: in the read verbs (cmd/history.zig), that a name decodes to a full digest before it is rendered and that a windowed or -n-capped listing's shown count matches the walked set; in the mutating verbs (cmd/checkout.zig), the preconditions at each destructive entry -- a full valid target id before update, both bisect endpoints present, exactly one pending merge or special op, every revert target in the managed set, and the checkout-record and managed-set agreement commit assembles a manifest from. Asserts only, no behaviour change; all sit on paths the e2e and simulation sweeps already drive, and all survive them. No assert fired, so no finding. check-in: 58763bb760 user: dmestas tags: trunk | |

cmd: TigerStyle assert-density pass over the verb layer
Mirror the H5a assert idiom (state invariants that already hold, no behavior change) across the split read and mutating verbs. Asserts only; wire output and exit codes unchanged. history.zig read verbs: - decodeFullId: a validated name decodes to a whole 20/32-byte digest, never a truncated prefix. - walkLog: every checkin/phantom line renders a full valid name, and the -n cap (parseLimitValue maps 0 to null) never overruns. - stat --artifacts / timeline: the listing projects the walked rid set, is capped by -n, and the printed count matches it. - tag add: the mint targets a check-in by its full artifact id. checkout.zig mutating verbs: - update/amend: the applied/amended target is a full artifact id. - bisect: both endpoints present before the span move. - merge: exactly one pending op (merge_parent XOR special_op) before applyMerge; revert restores only managed paths. - commit: checkout record and managed set agree before the manifest assembles; root has no pending op, merge and special exclusive, a child's parent resolved, every captured card tracked. closed check-in: 99e0c73447 user: dmestas tags: h5b-verbasserts | |

Merge h4-interop: bidirectional fossil interop smoke, push side included
The interop smoke only ever went one way -- fossil confirming what zit authored, always pull or clone direction. The push side of the wire, where capability negotiation and igot/gimme ordering live, was never exercised against the reference. Two scenarios close it, same policy as before (zit authors every byte; fossil only confirms; a mismatch prints the diff and its RFC citation, exits nonzero, and is a ledger decision). zit pushes a grown check-in to a live fossil server and a fresh fossil checkout must reconstruct the file byte for byte; then fossil commits a zit-authored blob that zit pulls and reads back through the library, re-verifying content against its artifact name. The smoke log now opens with the exact fossil version each run, so the conformance claim always names what it was confirmed against. check-in: 3ad0bf90da user: dmestas tags: trunk | |
