A stopped agent produces no journal row, so the next agent on that function learns
nothing — including that a scratch directory full of compiled candidates and their
match_one scores is sitting on disk. .run/journal_notes_local.jsonl is the same row
shape read through the same code path, so hand-recorded evidence reaches the pack
exactly as an agent's own note does.
Used immediately: six S71 agents that ran past 36 minutes were stopped to free their
slots; each now has a local note naming its scratch dir and stating that a stop is NOT
evidence of difficulty. All six are back in the draw pool and will draw at the Fable
tier per §413.
tools/journal_notes.py mines the agent journals per (binary, fn) and appends a
PAST ATTEMPTS section to the pack; claude_wave_packs.py calls it automatically, so
it is the default rather than a step to remember. Idempotent, and R48-safe (a note
stamped with a different binary is never served — §238 homonyms).
Measured before adopting (S71 wave 1, 50 one-agent workflows over the 210-function
real frontier where every target had already refused an earlier wave):
* 38/39 MATCH at closeness 0 (97.4%) vs S70's 124/131 (94.7%) on an EASIER pool
* 29/39 agents cite a prior attempt as what they used
* 4/39 banked by RECOVERING a body that already matched, from a path a note named
* 11/39 matched on the first compile
The two costs it removes are re-testing a measured-inert lever (§406 lists twelve,
§407 fifteen, §410 four — each paid for by an agent and never seen again) and
re-deriving a body that already exists on disk.
Also: jr_isolate_all places file-local `static` definitions with the region that uses
them instead of refusing the whole file. A `static inline` helper (§82.1) has no
address by construction, which is not a defect; the R32 guard was refusing these and
blocking the isolate on 4 of the 6 overlays whose CARVE-REFUSED functions it is the
named remedy for. Two regions using one static is still a hard refusal (duplicating a
used static is a byte change, R43).
