📝 LVI_SUCCESS and CLOSED -- Checkpoint_2 -- VLC Collwabware LVI configuration.mdTheme:

LVI checkpoint 2 — 2026-10-12

Follows LVI_checkpoint.md (written earlier the same day, left unchanged). Status change: the abort recorded in checkpoint 1 is superseded. The operator reopened the project and calls it stable.

Scope: [lvi] BBCode mod (LVIBBC.php v1.0.1), SMF 2.0.19 test forum at /smf20, VLC 3.0.24 on the operator's Windows PC. Live forum not touched.

1. Problem & Resolution

What happened since checkpoint 1

Item	Detail
Result	Operator: it worked with a fresh post. Project reopened and stable.
What was not reported	Which file types played in that post, and whether the 3GP played. Nothing here confirms the 3GP.
Why the fresh post worked	Not established. One candidate from the module's own header: SMF caches a parsed post body, and an attachment added to an already-cached post may not show until the cache is cleared. That is unverified as the cause here.

Status of the open items from checkpoint 1

Open item	Status
3GP (`attach=94`) would not play from the forum URL	Unresolved. The no-`Content-Length` / index-at-end hypothesis is still unproven. A fresh post working does not confirm or reject it.
The `HTTP 404` in VLC's log	Was for `/smf20/Silly2.3gp`, a path that does not exist. Not evidence about the hypothesis.
Quiet audio via the `.m3u` route	Unexplained. VLC's own volume read 243/256.
Guest permission requirement	Unchanged. VLC fetches as a guest, so the board must allow Guests View attachments.

New item: toolbar icon

The [lvi] editor button is registered with 'image' => 'lvi', so SMF needs an image of that name. The package ships none, so the button has no icon.
Operator wants the icon to be a mini VLC image and will make it himself. Claude declined to draw VLC's logo. The generic play-screen icon Claude supplied (lvi.gif, lvi_preview.png) is not going to be used.
File name must be lvi.gif. Expected location (Claude's recollection of SMF 2.0.x, not yet checked against an existing icon): Themes/default/images/bbc/lvi.gif. Size to match the operator's other toolbar icons (23×22 if they follow SMF's usual size).
The icon must go in through the Package Manager (package-info.xml file entry plus removal on uninstall), never copied by hand.

Waiting on the operator

lvi.gif (his own).
The installed LVI package zip.
One existing icon from images/bbc/, so size and format can be matched. This is optional if his icon is already 23×22.

2. Risk Analysis

State left behind (unchanged from checkpoint 1)

Test forum: Guests have View attachments on the General Discussion board. Test system only.
Test forum: LVI and its tag are installed, with CollabCore.
Operator's PC: VLC's Web interface is enabled with a password, reachable only while VLC runs. Listening address not checked.

New

The icon path and the .gif format are recalled, not verified. A wrong path would give a broken-image icon, not a crash.
Using VLC's logo is the operator's decision.
A package change touches install and uninstall. The uninstall must remove lvi.gif or the file is orphaned.
The zip rule "legacy zipper used" cannot be met by Claude, which has no access to the operator's tool. Plan: build with Python zipfile on a seekable file (no streaming data-descriptors) and check the flag bits. The release card will say "not used" unless the operator supplies the tool.

Still never tested

Live forum, SMF 2.1.x, browsers other than the operator's, non-Windows machines, members-only attachments (design limit: VLC cannot log in), visitors whose .m3u is not associated with VLC.

3. Code Change

None delivered since checkpoint 1.

Item	Version	Status
`LVIBBC.php`	1.0.1 (2026-10-07)	unchanged
`LVI_browser_test.html`	1.0.0 (2026-10-07)	unchanged

Changes announced in advance, not yet made (for the icon work):

Package version goes up, because its contents change.
Uninstall removes lvi.gif.
LVIBBC.php stays at v1.0.1. It is not touched. The operator may ask for a bump to keep the module in step with the package.

Release card: not applicable until a package is delivered.

Next step

On receipt of lvi.gif and the package zip: add the file to package-info.xml and the uninstall, bump the package version, add the manual version-history entry, run xmllint --noout on the XML, build the zip with a dotted never-reused version number, and send it with a release card.
