Module side: 4 of 10 D03 owners are byte-identical to the reference and 4 more
are pure upstream drift (fit/budget/compaction/capability_evidence - nothing to
do, upstream bytes stand); the one split lands again from tip bytes:
ouroboros/context_runtime_facts.py (241 lines, 4 fact builders, 0 handle
rewrites - the leaf is projection-only by design) with the triple proof green
on every symbol (ast/tokens/bytes), and the facade shrinks 1590 -> 1380 with
the oracle's in-place re-export block and noqa discipline. The drift-probe
caught the reference leaf byte-falsified as a copy source: upstream b14ba397
rewrote _delegation_capability_fact (configured_route dropped, profile
evidence added) - copying the oracle leaf verbatim would have reverted that
feature; recorded in docs/v7next/LEDGER_CORRECTIONS.md (entries 7-11).
Test side: the 2080-line tests/test_context.py giant completes its S7a split
from TIP bytes (the giant drifted upstream, so oracle files could not be
carried blind): runtime_section (502) / memory (the D15-carried file
re-derived from tip and proven identical - not stale) / drive_state (233,
==oracle) / advisory_review (300, ==oracle) / _context_shared (49, ==oracle),
remainder 612. Lossless: 73==73 test functions, zero lost, zero added, and
the 15 memory tests that ran TWICE since the D15 carry are deduplicated. Two
upstream test rewrites (actor-scoped backlog digest, profile-evidence
delegation fact) travel to the oracle's destination as identity
continuations; 8 unrowed upstream recent-chat tests stay in the remainder
pending F5 rows. Oracle adaptations of test_context_fit_integration /
test_loop_compaction (loop -> loop_model_call) are foreign-domain spellings
whose leaf does not exist on this tree - reported, not applied.
size-ratchet manifest regenerated with the official tool: test_context.py
leaves GIANT_PATHS, context.py enters the band from the 1501-1600 zone with a
FLAGGED rationale (not self-approved). 74+110+228 tests green in isolation at
the lane base; ratchet lane 5 passed; ruff F clean; HEAD held through every
pytest run.
