Order 20260908T195801Z. Findings 4 and 5 from the S7 acid test, then the two things
finding 99 measured and deliberately did not fix (D3, D2).
No user-facing surface changes: no new flag, no new command, no changed output
contract. Both seams are internal (the pre-pass rendering, and the shape a tool
answers a model with), so [skip-docs] rather than a README edit that would describe
nothing an operator can do differently.
FINDING 4 -- MEASURED, NOTHING BUILT. K2's price schedule IS readable without
guessing (8 column spans, 71 of 91 non-blank rows give >= 2 cells, the split stable
for K = 2..64). But 0 of 92 rows name all three of code/quantity/unit_cost -- also
under a looser substring match -- and 0 of 91 data rows carry code + quantity +
amount. The triple is not formatted away; it is not in the document. It is a price
SUMMARY plus nine rate cards whose unit-price columns are empty (pre-award). The
order's binding decision rule therefore falls against building:
--derive-cost-baseline keeps refusing, and MAJOR-4's own honesty limit holds.
FINDING 5 -- BUILT. Measured on the actual rendering path (concept_text, not the
raw file): the delivered excerpt is 104 lines / 67 245 chars, carrying 208 interior
whitespace runs, 117 of them >= 100 and the longest 887 -- 56 806 of 67 245
characters = 84.5 %, over 72 of 104 lines. collapse_padding, called from
_data_blocks (the one renderer both arms share, and therefore AFTER
verify_against_bundle -- collapsing in concept_text would break every payload's own
digest), gives -72.4 %: line count invariant, non-whitespace byte-identical, leading
indentation untouched, no number changed.
F99-D3 -- read_file / read_dir / read_bundle now RETURN their refusal. MAF turns a
tool raise into "Error: Function failed." (_tools.py:1410-1432, :1427) and counts it
against DEFAULT_MAX_CONSECUTIVE_ERRORS_PER_REQUEST = 3, so everything the refusing
arm knows is destroyed on the way out. The gates are unchanged; the property they
exist for -- the reason travels, the bytes never do -- is now asserted explicitly on
the returned value. The arm is keyed on named classes, never bare Exception, because
ExplorationError is itself a RuntimeError subclass.
F99-D2 -- the invariant row, plus one for finding 5 (a stated deviation from "one
row only": finding 5 is a separately built seam and the ledger's standing rule
requires its own row).
19 existing arms rewritten, never deleted and never weakened: where the class
carried a distinction, the refusal KIND carries it now.
13 mutations, all red against the whole suite (W1-W5, M1-M8), each restored from
scratchpad with shasum -c. Control 1543 passed / 5 skipped (from 1529/5, a strict
superset, 0 removed). Golden demo-transcript.stdout unchanged
(shasum -a 1 of the CONTENT = ea8c534773acdbe41ae68f2c55724d69aaf8be4f).

F3 and F4, the two findings the S7 acid test (session 98) reported and left. The order required
both descriptions to be treated as PREMISES. One held; the other was felled before anything was
built on it.
F3 -- premise FELLED, asymmetry real. The order read arm C's two refused calls as "the path names
a document that EXISTS". Measured against the base that ran: its root holds 27 directories named
del-ii-bilag-N-... and 12 documents named inbox-del-ii-bilag-N-....md, and the requested path
matches NEITHER -- it is the directory naming convention applied to a document whose real name
carries an inbox- prefix. So the two live rounds were the UNKNOWN-path class, and this delivery
does NOT recover them (gated). What IS real: read_file on a directory has named read_dir since
session 95, while read_dir on a document named neither the rung nor the path.
okf.DocumentPathRefused closes that one direction -- a ValueError, a SIBLING of BundlePathNotFound
rather than a subclass, built from context_files (never files) and through the same in_dimension
predicate the listing uses, quoting the document's REAL name so what it hands back resolves.
F4 -- premise HELD, option (c) felled by measurement. All four live artefacts stamped
cost_baseline_anchored: False and each arm invented its cost codes. derive_cost_baseline refuses
against the delivered base: K2's price schedule is a pandoc SIMPLE table with ONE column header,
so making --derive-cost-baseline reachable there would mean inventing a rule for an unmeasured
form -- MAJOR-4's own honesty limit. Chose (b) over (a): --require-cost-baseline /
run_project(require_cost_baseline=...), OPT-IN and never default, so every bundle without a
cost-baseline.json runs unchanged. The gate sits where both branches have bound baseline and ABOVE
the dry-run cut, so it fires on the free trip too and, on the paid one, before the first model
call. Three CLI refusals by name, each with an rc-0 control.
12 mutations, all red against the WHOLE suite. Green control 1493/5 -> 1511/5 (+18 node-ids, 0
removed); golden demo-transcript.stdout BYTE-UNCHANGED (shasum -a 1 of the CONTENT =
ea8c534773acdbe41ae68f2c55724d69aaf8be4f). No paid run: both findings measured offline.
