Every correction here is to something I wrote earlier in this arc. Original text
is preserved in place; nothing was rewritten to look right in hindsight.
ADR-0264 §4.2 — CORRECTED block. I sized the eleven band ceilings from per-TERM
exclusivity; `resolve_domain`'s predicate is per-PAIR, which is looser, so every
ceiling was understated and one verdict was wrong: systems_software_causal is
720, not 630, i.e. reachable rather than impossible. Seven of eleven bands
cannot reach 657, not eight. Downstream conclusions survive — physics·modal (480)
is still impossible and philosophy_theology·modal is still the target.
ADR-0264 R5 + DIVISION-OF-WORK ×2 + compile_premises docstring — the
"verdict-identical" claim is exact only where the full family was READABLE. Over
MAX_PREMISE_SENTENCES, full-family compilation refuses outright, so narrowing is
verdict-IMPROVING there. Read literally the unqualified phrasing implies a
17-chain family keeps declining, which is backwards — the opposite of the
unblock.
E2 rename staleness, 4 sites: ADR-0256 (Accepted) named
`gold.py::assert_corpus_sound`, which #119 deleted; the plan's E2 item and
DIVISION-OF-WORK's §2 row, §4 heading and "renaming after that is strictly more
work" reasoning were all still written as pending.
DIVISION-OF-WORK §0b — new status table: which PR each unit is, what stacks on
what, and the four things the units found that the plan did not predict.
Adds the arc-close brief from ARC-CLOSE-TEMPLATE.md. Its §3 (falsified
assumptions) is the section that cannot be recovered from the diff: nine
entries, five of them corrections to my own claims. Records that the
articulation trigger is not merely unmet but STRUCTURALLY unmeetable — the
previous arc left it unrecorded, which is what kept it re-triggerable — and
names four pieces of stale reasoning still in the tree, with files, since that
is the class of staleness nobody greps for.
[Verification]: in-worktree on canonical CPython 3.12.13 with `uv sync
--locked`: smoke 569, deductive 291 — both baseline, since the only non-doc
change is one docstring.
Closes the Opus share of the curriculum-license-loop arc. Three deliverables,
all docs -- no production code.
1. E1-R7-ASSERTION-SPEC.md -- the Opus half of Phase E1. The code move was
already specified by runtime_contracts.md ("defer the single sink emission
to the pipeline serve boundary"); what to ASSERT was not, and the default
sink is None, so nothing exercises the path. Eight invariants (I1-I8) plus
three mechanism rulings (M1-M3), each with the silent failure it prevents.
The three mechanism rulings are the value. M1: stage a turn_log INDEX, not
a captured TurnEvent -- a captured copy is the pre-override snapshot, i.e.
the defect with extra steps. M2: attach_telemetry_sink must NOT flush a
staged turn event, which is the OPPOSITE of what it correctly does for
_pending_reboot_payload; the reboot payload is final when buffered, a turn
event is mid-flight, and flushing on attach would silently restore R7. M3:
the runtime cannot detect whether a pipeline will run (the pipeline wraps
the runtime), so deferral must be explicit opt-in and the no-pipeline path
must stay byte-identical.
All ten source citations verified against HEAD.
2. Plan of record AMENDED with four falsified premises from Phases A/B, with
the original text preserved:
- physics·modal was the wrong first target -- its ceiling is 480 against a
657 threshold, and 8 of 11 bands cannot reach 657 at all. Vocabulary is
the constraint, not chain count. Retarget: philosophy_theology·modal.
- MAX_PREMISE_SENTENCES=16 caps a family at 16 chains, so ADR-0262 §5.1's
own remedy (~219 relations) collapses the band at row 17. No curriculum
band can earn SERVE until premise compilation is query-scoped. New
implementation phase precedes ALL content work.
- authoring a negative today serves a confident wrong "Yes", not UNKNOWN.
- 21 of 25 ratified deduction bands are short on distinct evidence.
3. DIVISION-OF-WORK updated for the handoff: §0 status table with branch names
and merge order, the revised order (E2 -> R5-R7 -> C -> D -> E1(code) ->
parity), the new R5-R7 unit specified to gate-level detail, and a standing
"do not fix" on the deduction ledger exposure.
One correction to my own earlier text: §4 told Phase C to mirror the
deduction producer "exactly". That would replicate the padding -- a flat
CASES_PER_BAND=720 cycling a 28-instance space. Phase C now points at the
`estimation` producer instead (660 distinct, zero repeats), and must
register in AUDIT_SOURCES.
[Verification]: uv sync --locked on canonical CPython 3.12.13; in-worktree
smoke 555 passed, deductive 285 passed (this branch is off main and carries
neither ADR-0264 nor the Phase B tests, so 555 is the correct baseline here,
not the 569 that holds on the stacked A+B branches).
Two prior arcs closed on "the binding constraint is ratified curriculum volume,
not machinery." Verified against code 2026-07-25: the machinery half is wrong in
a load-bearing way, and the correction is the reason this arc exists.
evals/curriculum_serve/practice/ does not exist. seal_ledger exists only for
deduction (evals/deduction_serve/practice/runner.py:96), yet
chat/curriculum_serve_license.py's own docstring names
evals.curriculum_serve.practice.runner.seal_ledger as "the only writer" of the
artifact it reads -- that writer was never built, and
chat/data/curriculum_serve_ledger.json does not exist. And the ceremony stops
short: RatificationReceipt.pending_stages = (arena_queue_entry, ledger_reseal).
So the pipeline is author -> ratify -> ??? -> ??? -> license -> serve. Authoring
curriculum today cannot earn a license at ANY volume. Content is necessary and
currently insufficient. The build is still modest, because oracle.py is already
an independent decision procedure usable as the gold tether and ADR-0263 already
extracted the sealers for exactly a third instance.
Two measured facts shape the content work. `refuted` has NEVER been produced --
the physics lane gold is entailed 14 / unknown 12 / declined 6, and no corpus row
can express it. And bands key on (domain, operator_family), so negative content
must live INSIDE operator_family "modal" with a row-level polarity marker; a
separate modal_negative family would create a new band at n=0 instead of adding
refuted volume to the target band -- the easiest available way to waste the whole
authoring effort.
DIVISION-OF-WORK.md records the tiering criterion and why it is not difficulty.
The evidence does not support a prestige split: in the same 48h window Sonnet 5
found the DEFAULT_SINK bug that wrote outside the repository and did the
six-worktree public_demo archaeology, while Opus 5 mis-diagnosed the CGA hot path
by multiplying a microbenchmark by a call count. Model tier was not the variable;
verification discipline was.
The split is therefore: would an error here be caught by a gate, or is it silent?
Two units are silent-failure BECAUSE THEY ARE THE GATE -- the negative-curriculum
epistemology (wrong => corpus encodes falsehoods and wrong=0 still passes, since
lane gold and the oracle both read the same rows) and the volume-honesty invariant
(wrong => conservative_floor cannot tell 657 independent facts from 16 asked 41
times, so the ledger clears theta=0.99 having earned nothing). Those get Opus.
Everything loud goes to the cheapest competent tier.
Also records the ordering correction: the epistemology ADR must precede the
generator, or the generator gets built twice.
[Verification]: docs-only; no code paths touched. Every referenced path confirmed
to exist and all five line citations confirmed accurate at HEAD (gold.py:1163,
curriculum_serve/runner.py:71, discovery_yield.py:67-70, entail.py:125,
curriculum_surface.py:184). Pre-push gate runs on push.
