AX sweep findings:

HIGH — Session ID inserted into h1/title without HTML escaping (html.go:87, :93)
HIGH — Raw tool name written into data-tool and class attributes without escaping (html.go:168, :173)
HIGH — Unescaped values interpolated into VHS script lines (video.go:46, :60)
MEDIUM — ListSessionsSeq uses 1MiB scanner buffer instead of 8MiB limit (parser.go:157-158)
MEDIUM — No sess==nil guard before dereference in rendering paths (html.go:22, video.go:19, :56)
LOW — Errors silently dropped in prune/search/list flows (parser.go:221, search.go:36-37)

Fix all, add tests.

Codex Audit Findings

RESOLVED (already fixed)

Path traversal: FetchSession rejects IDs with .. or path separators (parser.go:238-247)
XSS: RenderHTML escapes all user strings via html.EscapeString (html.go:155-200), verified by TestRenderHTML_SpecialCharacters_Good

STATUS

Security findings from original issue appear to have been fixed in a prior commit. Tests verify the fixes. This issue can be closed or verified manually.

Fact-Finding: Convention Drift Scan

1. SPDX Headers: PASS

All Go files have SPDX-Licence-Identifier: EUPL-1.2

2. Usage-Example Comments: NEEDS WORK

Most exported identifiers lack usage-example doc blocks

3. stdlib Usage (AX violations)

fmt.Sprintf: 30+ locations across analytics.go, html.go, parser.go, search.go, video.go
strings.*: 50+ locations across all files
errors.New: none found (clean)

4. UK English: MOSTLY CLEAN

Go comments clean. Markdown docs have: behavior (GEMINI.md:76), License/licensed (README, CONTRIBUTING, docs)

5. Test Coverage: 92.4% overall

Weak spots: RenderMP4 (21.1%), EventsSeq (66.7%), ListSessionsSeq (84.4%)

Package is in good shape — main debt is fmt.Sprintf/strings. AX compliance and RenderMP4 test coverage.*
