The standing link board is the one MULTI-WRITER booth -- every agent session
appends operator-facing URLs to it. "Delete the folder" was the only
granularity available, so removing one dead link meant hand-editing markdown.
It is 32 rows and only grows.
booth links row number, entry id, raw row
booth unlink 3 by row number
booth unlink 8b40e0a5 by entry id (what the UI's x posts)
POST /b/<name>/unlink form field `entry` = content id
ROWS ARE ADDRESSED BY CONTENT ID, NEVER BY POSITION. The board is append-only
and multi-writer: another session can post between listing it and clicking x,
and an index would then delete a neighbour. An id either matches the row you
saw or matches nothing. A row number typed at the CLI is resolved to its id
BEFORE anything is deleted. Appends and prunes now take the same flock on
.links.lock, so a post cannot be lost inside a prune's read-modify-write.
UI: a booth carrying links.md renders as rows -- description, URL, provenance,
copy button, per-row x -- instead of a markdown blob. links.md is filtered out
of the gallery so it does not appear twice; the header counts LINKS not files;
the empty-state and the one-click "Wipe now" both stand down for a board (same
rule as the kept lane: nothing durable is one click from gone).
booth/links.py extracted, STDLIB ONLY. The CLI needs this logic and must not
require the service venv -- importing app.py drags in FastAPI, so deleting a
line from a text file would have needed a web framework installed.
THREE BUGS FOUND BY TESTING, all in the shell wrapper while the module was
correct throughout -- module-only tests would have caught none of them:
- `[ "$n" -eq 0 ] && echo ...` as the LAST statement made `booth links` exit 1
whenever the board had rows. `unlink`'s index lookup calls it inside $( )
under `set -e`, so a successful listing killed the caller and the removal
silently did nothing while reporting success.
- ids are 8 hex chars and roughly one in forty is ALL DIGITS; those were read
as row numbers, resolved to nothing, and removed nothing. Now disambiguated
by the id's actual shape, not by "is it numeric".
- filtering links.md out of the gallery left `items` empty, so a full board
rendered "This booth is empty" and an empty <div class="gallery"> under 32
visible rows.
87 tests (was 76): parser tolerance of hand-written prose, content-id
stability across concurrent appends, removal precision, UI branch behaviour
for board/normal/empty booths, and subprocess CLI tests pinning the two shell
bugs. Deployed to nh3-dev and verified against the live 32-row board
read-only; board file byte-identical afterwards.
