From 8ffd10c2ac0877a2c0f6ad5d20abfbf94da3483f Mon Sep 17 00:00:00 2001 From: Snider Date: Mon, 27 Apr 2026 18:17:50 +0100 Subject: [PATCH] fix(session): address all CodeRabbit findings on PR #5 6+ findings dispositioned. AX-6 maintained (stale testify refs removed). Code: - parser_test.go: fixed EOF-truncated JSONL fixtures - parser.go: ListSessionsSeq skips transcripts when quick scan fails; added oversized-line coverage - parser.go: symlink pre-check replaced with O_NOFOLLOW descriptor opens + Fstat for FetchSession and ListSessionsSeq (TOCTOU-safe) - test_helpers_test.go: assert* helpers changed from fatal to non-fatal reporting - tests/cli/session/main.go: derived expectations from current code (CodeRabbit's suggested literals were incorrect for current impl) + filepath.Join nit; preserved correct behaviour CI / config: - .golangci.yml: migrated to v2 schema - tests/cli/session/Taskfile.yaml: 'test' broadened to run go vet + go test + CLI smoke - PR title: made specific Doc: - AX-2 docstring coverage: comments added to all Go funcs in touched files (closes pre-merge docstring warning) - README + CLAUDE.md + CODEX.md + CONTEXT.md + TODO.md + docs/{architecture,development,index}.md + kb/Home.md: removed stale testify references, aligned to stdlib testing Disposition: - SonarCloud / GHAS: no separate PR comments/checks; gh pr checks only reports CodeRabbit. RESOLVED-COMMENT. Verification: gofmt clean, golangci-lint v2 0 issues, GOWORK=off go vet + go test -count=1 ./... pass with explicit cache paths, task -d tests/cli/session clean.
