Raw Blame History

Session changelog 2026-07-21 (third session) -- disconnect collapse + netem install verification

One changelog per session (GA-R2/D1). Status lives ONLY in docs/CURRENT-STATE.md; this file is narrative + reverts. Predecessor (close-and-delivery session, disconnected after the operator ran the netem-tc install): docs/changelog-20260721-close-and-delivery.md.

1. Lingering-session sweep (read-only; nothing to collapse but records)

  • Verified: working tree clean at pushed HEAD 8a9c04c; zero unpushed commits; single worktree; no stray run-logged windows or tofu processes; branches = stage branch + main only, both synced. The disconnected session's seven deliverable commits were ALL already durable -- the only outstanding items were its ledger bookend and the record of the operator-run netem-tc install.
  • One divergence FLAGGED (logged, not fixed -- queued finding): ledger-scan.sh omits D-131 from its PROPOSED/OPEN list because the Status line begins "PARTIALLY RULED" (D-129's "OPEN / PARTIALLY RULED" phrasing is caught; D-131's is not) even though sub-2..4 are OPEN. Candidate fix: widen the scan's status-line match or adopt a status-wording convention. No information is lost today (the ledger's hand-seeded block carries D-131).

2. netem-tc sudoers install VERIFIED (read-only)

  • The install command itself was operator-run interactively in the predecessor's window (fragment-header command, verbatim). This session re-verified without root: installed file 0440 root:root, byte count identical to the repo fragment (1888), and non-interactive sudo -n -l grant checks exit 0 for both verbs on virbr5 (the step-E target) plus spot checks on virbr7/virbr3 -- which also proves the installed file parses (a sudoers parse error disables the file). Capture: docs/audit/netem-sudo-install-20260721.txt.
  • CURRENT-STATE step-E paragraph corrected in this same commit (GA-R1 C1/C2): install PENDING -> INSTALLED+VERIFIED; remaining path stated (wire modules/netem-link into the outer root from its HELD comment, adds-only plan gate, then the gated placeholder run).
  • Revert: git revert this commit (records only); to remove the live grant: sudo rm /etc/sudoers.d/netem-tc && sudo visudo -c.

3. Predecessor bookend LANDED (this commit)

  • Bounded SESSION CLOSE entry for the close-and-delivery session appended to docs/session-ledger.md (GA-R4; second same-day disconnect-then-successor-lands cycle, same pattern as item 1 of the predecessor's own changelog).
  • Revert: git revert this commit (returns the predecessor to not-durable state; live cloud untouched).
