Vuong Hoang d37b81ab9f memory: snapshot — U5 released at v0.3.0, and the index goes two-tier
The two dated log sections had never been split, so every one of their 29
entries sat inline and the startup index had grown to 372 lines — which is
the cost the two-tier scheme exists to remove, paid on every session that
reads the file. 27 entries were over threshold. All 29 now have a detail
file under persistent-memory.d/ and a one-line index entry that routes
rather than restates. Index: 372 -> 93 lines.

No archival. The soft cap fired, but every entry in this repo is dated
2026-09-21 or later, so the under-14-days guard held all of them back — and
the split alone took the index well under the target without moving
anything out of the active file.

The in-flight section is rewritten for the post-release state: nothing is
in flight, no gate is outstanding, and the next unit is explicitly recorded
as the operator's undecided call rather than as a plan. The session's
recommendation (U4, on three grounds) is written down so it does not have
to be re-derived, alongside the two alternatives and why they are
alternatives.

Two dated predictions are carried forward with their dates and their
instruments: the U5 adoption re-measure on 2026-09-29, which already reads
3 of 24 announced and 2 with a why from peers told nothing, and the
.forever re-count a fortnight AFTER U4 lands, which is U4's own success
criterion and is destroyed by running it early.

U2 (marks) landed — one primitive for three mechanisms

2026-09-21 · booth

U2 (marks) landed. One primitive replacing three mechanisms. pick / note / flag in one .marks.json per booth, one read path (marks_for), one openness predicate (open_marks), rendered beside the artifact on the tile, at full size in the zoom, and in the panel. flag and note had no write path at all before this — the selection loop (golden-candidates, sindra-finalists, the pancake-* ladders) was running through chat. 242 tests. Details worth carrying: asks.py kept normalize_ask and gained build_answer (the 2026-09-09 partial-answer semantics preserved by moving, not rewriting) and LOST its five sidecar-storage functions; GET /b/<n>/marks.json was added because remote sessions polled <stem>.answer.json over HTTP and the sidecar's removal would have taken that capability with it; /b/<n>/asks 308s to /marks.
