volt: Q161 -- jobs-table entry point is a bash wrapper over a grader that can say 'cannot grade'

wizard-work/ledger/CHECK-2026-11-02-jobs-table landed at 2e57e6b as a Python program with a python3 shebang, so `bash <path>` -- the invocation the q143 sweep, verify.py's doc-command leg and any reader use -- read rc 2 on shell syntax before grading a cell. Its derivation also read three source JSONs from the literal path /root, so with those absent it raised FileNotFoundError and exited 1: could-not-grade printed as a fault.

The grader moved to grade_jobs_table.py; the path keeps a bash wrapper. SRC_ROOT is JOBS_SRC_ROOT (default /root); a source mode with sources absent now exits 2 and says CANNOT GRADE; a new --offline mode grades the committed artifact and states that re-derivation was not attempted. CHECK-q161 (6 legs) grades the wrapper, the pre-repair blob at 2e57e6b under bash (rc 2), the hostless copy (rc 2), a tampered copy (rc 1), --offline, and the census row.

 **What this is.** One row per item of `WORK-QUEUE.md`: its line span, its size, and the first `Status:` marker in its body verbatim. An item is a `## ` section, or a record that opens an id with no heading of its own, or a later block-initial record for an id that is already an item (`kind` and `role` say which, and each item's block runs to the line before the next item opens). Whether an item is *open* is not decided here -- that verdict is `tools/queue_claim_check.py`'s, and this document does not overrule it.
 
-**What it exposes.** The queue is two-tier. 108 sections carry 95 ids because 13 ids own a second, continuation section; 60 further ids are opened by a record and own no heading at all, and they have rows and extents here -- 143 record blocks in all, 83 of them a later closure or correction for an id already opened. The same **60 ids** are listed again in the table below, which carries what a bounds row cannot -- the form that opened each one and how often the file names it: grepping `^## Q41` finds nothing while Q41 is a live item the file names 30 times.
