docs(agent-return-channel): record what akashic's full-scale numerator closes, and what it does not

akashic-intelligence recovered its four S25 agents' on-disk final text against
the full 3730-line / 277 KB plan (commit e281a9d): 4/4 produced correct output,
delivery alone failed. That closes the size-dependent-work question the caveat
left open. It does not close the returning arm above 66 lines -- all four of
their cells were named -- so that stays stated as inferred, not observed.

**External measurement closes half of that (2026-08-17).** `akashic-intelligence`
recovered its own S25 transcripts from
`~/.claude/projects/<slug>/<session>/subagents/` and read the last assistant
text block out of each. Denominator: 4 of 4 agents, all **named**, all against
the full 3730-line / 277 KB plan. Three produced valid JSON review output
(17, 8 and 13 findings); the fourth was their PONG control and produced
`PONG`. Their commit `e281a9d`.
What that closes: **the work is performed at 3730 lines.** No size-dependent
failure of the agent's *reasoning or output* exists at that scale — the named
arm produces correct final text at 66 lines and at 3730 lines alike, and only
delivery fails, identically at both. The 38 recovered findings were re-used
instead of re-run.
What it does **not** close: their four cells were all named, so the *returning*
(unnamed) arm still has no measurement above 66 lines. That a plain subagent
returns a 21 KB result at that scale is inferred, not observed. Stated as
inferred.
Their PONG control also carries the same lesson as cell 1 above, in a third
repo: S25 reported that agent as having "gone idle without sending PONG". It
sent PONG. Absence of *delivery* was read as absence of *work* — the same
face-4 error, three times in one evening.
