BE-007: root out ROWS; serialize ULOG→HUNK via a plain utility fn

ROWS (dog/ROWS.{h,c}) is an unnecessary typed subsystem — 195 refs across 18 files (rows, rows_row, ROWSnav, ROWSdiscipline, ROWSOpen/Close/FeedRow/FeedRec) — for what is just serializing a ULOG event sequence into ONE H hunk as a token stream. Replace it with a single utility FUNCTION in HUNK or ULOG, with NO new data types (operate on existing ulogrec/hunk/u8b/u8cs). Delete ROWS entirely, repoint every caller, and restore correct verb output. It is also currently BROKEN (bannerless hunks get rebased into per-row labels — the POST-022 wreckage). This REVERSES and supersedes BE-005 (and the ROWS wiring its children POST-018/ GET-026/STATUS-001 landed); it subsumes POST-022.

Input

Context

ROWS adds types and a builder for a job that is one serialization function.

• Real job: a ULOG row (ts, verb, uri) → tokens appended to ONE hunk (the <date> <verb> <path> table with per-column toks + a hidden nav URI per row), flushed via HUNKu8sFeedOut. No state object is needed.
• Callers (18): sniff/{LS,GET,PATCH,PUT,POST,DEL,SNIFF.exe}, dog/{ULOG,HUNK}, keeper/{WALK,KEEP.exe}, beagle/BE.cli, + their tests.
• Currently broken: ROWS rows emitted with no active table become empty-URI hunks that HUNKu8sRelay rebases to the mount path → a bare label per row (POST-022).

Goals

Delete ROWS; one utility fn; identical (correct) output.

• Add HUNK/ULOG utility that serializes a ULOG event (or a slice of them) into a hunk token sequence — NO new types; nav scheme passed as a plain param/ron60, not a ROWSnav enum or rows_row struct.
• Remove dog/ROWS.{h,c}; repoint all 18 callers to the utility fn.
• Verb output (status/post/put/get/diff/ls banners) byte-correct; the POST-022 per-row-label / full-history wreckage fixed by construction.

Constraints

• ABC idioms; NO new data types. Keep the per-column toks + hidden per-row nav URI behavior via fn params, not a struct. The tty-stream vs one-hunk --tlv modes come from HUNKMode, already global.

WIP

Design decisions

(pending)

TODOs

• Inventory the 18 callers + the 195 refs; classify each ROWS call's intent.
• Design the utility fn signature in HUNK or ULOG (input: ulogrec(s) + nav param; output: u8b/hunk). No rows/rows_row/ROWSnav/ROWSdiscipline.
• Repoint callers; delete dog/ROWS.{h,c} + its tests; update INDEX.md, CMake.
• Repro-first: keep the verb-output tests green AND fix the POST-022 wrecked output (assert bounded, prefixed sub-push output) — confirm failing pre-change.

Blockers and bummers

• Large surface (195 refs/18 files). Coordinate with in-flight POST-021 (narrow BASS-carve fix in keeper/WALK.c) — leave its walk/BASS logic alone, only remove ROWS from the output path; expect a reconcile.

Outcome
