P13-S27 landed at 4df8e25. Four documents carried live statements that the
landing invalidated, and they had to move together: updating the ledger alone
would have left the active S16 contract contradicting it.
CLAUDE.md
- Track head: P13-S27 LANDED; P13-S16 unblocked, contract still DRAFT.
- The T1b/S27 collision is resolved. T1b is NOT thereby free -- it stays
blocked on Ruling B blocker (ii), versioned decode. A future
epiphany-bundle rung re-creates the collision on its own terms.
- Green baseline 1570 -> 1577, and marked as the single origin for the count.
- "One live constraint" rewritten: the blanket no-canonical-base prohibition
is lifted, replaced by the authority check (accepted when
reduction_algorithm_version equals CURRENT_REDUCTION_ALGORITHM_VERSION,
currently 0; CanonicalBaseRequiresRebuild on both read and write paths;
legacy epoch still refuses outright), plus the bump discipline and the
synthetic_for_fixture / production_caps split.
spec/HANDOFF_2026-08-07.md -- a dated snapshot, so it keeps its text and gains
a POST-S27 UPDATE block at the top that is the single place the new state is
given. Each invalidated site now points there instead of restating:
§1.2 constraint (dated record), the suspended conformance wiring (restored),
ReductionAuthorityUnavailable (deleted, replaced), §1.4 chain state, §2.6 and
§4.3 collision, §4.3 items 7 and 9. The three 1570 repetitions are replaced by
a pointer to CLAUDE.md -- a figure kept in four places goes stale in three.
spec/CONTRACT_P13S16_PROJECTION.md
- Status: DRAFT, UNBLOCKED 2026-08-09, NOT RATIFIED and therefore NOT
dispatchable. Pin 0's blocker is discharged; core_spec.tex:11614 is met.
Original status retained verbatim.
- Pin 11 amended: it mandated a ledger state of "blocked on P13-S27," which is
now false -- a pin requiring a false ledger state would put the contract in
contradiction with the ledger it governs. Its instruction to file S27 in the
same edit is discharged.
spec/PASS13_CANDIDATES.md -- appended to both cells, per the append-only
convention.
- S16: unblocked, with the "additionally needs pin-2a's disposition" sentence
explicitly superseded (settled from outside S27 by the format rung's pin 8);
unblocked is not dispatchable; first act is bumping the authority to 1.
- S27: accepted and landed, with the gate figures, and a correction to pin
10's own wording -- it said S16 becomes "dispatchable," but by this repo's
definition S16 is unblocked, not dispatchable. Same unblocked/dispatchable
conflation S27's round 1 committed.
Documentation only: no .rs or .toml touched, so the gates re-run against the
landed tree stand unchanged.

The handoff was comprehensive as a document and unreachable as a
bootstrap. An agent starting cold on a new machine reads CLAUDE.md
automatically; it would have to be told to open spec/HANDOFF_2026-08-07.md,
and the rules this work actually ran on lived only in conversation and
in an agent memory directory that git does not carry.
So the method is now a tracked file and the handoff is the state it
assumes. CLAUDE.md carries what an agent must not learn by discovering
it: contracts are frozen after ratification and defects are reported
rather than patched in place; the touch table is the staging allowlist,
with the two files that keep escaping it named; mutation-first, and a
compile error is not a test failure; verify subagent claims by re-running,
because agents here have misattributed failures and guarded the wrong
path; never git add -A, never reset/checkout/stash against a tree another
session may share; never cargo fmt --all, since it crosses into spikes/
through path dependencies; xelatex not pdflatex; the green baseline; and
the live no-canonical-base constraint that makes correct refusals look
like bugs until P13-S27 lands.
The handoff gains §0a pointing at it, and saying plainly what an agent
does not inherit — the memory directory and the conversation — so a thin
inheritance is stated rather than papered over.
The editor/T4 track's half of these rules is recorded as observed from
its contracts; that session should review it.
