Feat: Name unbridged CONNECT tunnels in the events ACTION column - #886
Conversation
An opaque CONNECT stood as a row of em dashes: no ACTION, no PLUGIN, no STATUS. That is accurate — the bytes inside are TLS, so no plugin ran, no protocol was parsed and there is no status — but it reads as a request that failed or that the pipeline ignored, which is how a routine egress tunnel came to look like a regression. Such rows now show "tunnel" in ACTION, so the row says it is complete as it is. Only when nothing acted: a gate can deny a CONNECT on the tunnel-open itself, and that deny keeps the headline. A bridged tunnel never reaches the branch — buildEventRows folds it into the decrypted inner request, whose own action is the interesting one — and a plain passthrough keeps its em dash, since otherwise every unprocessed row would claim to be a tunnel. The label lives in a rowAction wrapper rather than inline in rebuildEventsTable so it is testable without a terminal. Verified against a 344-event capture from a live server: 17 rows that were blank now read "tunnel", and the observe/modify rows are unchanged.

A blank row that reads as a failure is a real reporting bug, and naming it is the right fix. The three cases the label deliberately does not claim — a denied tunnel keeping its deny, a bridged tunnel deferring to the inner action, a plain passthrough keeping its em dash — are each tested, and pulling the logic into rowAction so it is reachable without a terminal is what makes that possible.
Verified by running it, not by reading it
| Check | Result |
|---|---|
| The behavior tests are real guards | I removed the rowAction tunnel branch to reproduce pre-PR behavior: TestRowAction_UnbridgedTunnelIsNamed and TestBuildEventRows_TunnelRowsAreLabelled both fail, reporting exactly the "—" this PR replaces. Restored, both pass; full abctl suite green |
The invs → er.invocations() swap is behavior-neutral |
The call site already computed invs := er.invocations() for the hideInactive check, and rowAction calls that same pure method — so every non-tunnel row renders identically. Confirmed by the suite, and it is the one thing in this diff that could have changed unrelated rows |
| No cross-pane inconsistency | eventAction had exactly one caller (the row builder), and nothing else in abctl renders an action — no detail pane, no export. So there is no surface left showing — where the table now shows tunnel |
eventAction really does return "—" for nothing-acted |
events_pane.go:359. The action == "—" guard is correct, and the bare literal matches how this file already spells the em dash elsewhere rather than introducing a new convention |
| The motivation checks out in the code, not just the screenshot | eventMethodValue populates only from A2A / Inference / MCP extensions, so METHOD is "" for a CONNECT, and statusCell returns "" at status 0. METHOD, STATUS and ACTION were all blank — the label really is the only thing on that row that can identify it |
.claude / .vscode gate; secrets |
no matches |
| CI | 24/24 pass; one commit, signed off |
One thing I checked and then dropped, so it is on record rather than raised as a demand: I expected to argue that CONNECT belongs in METHOD, leaving ACTION to mean "plugin verdict" alone. It does not. eventMethodValue is a protocol operation column despite the name — A2A method, inference model, MCP method — and an opaque tunnel has no protocol operation to put there. ACTION is the defensible home.
Worth one line in the events-schema docs, though: tunnel becomes the second value in that column that no plugin emits (— being the first), while the column otherwise renders the documented five-value action vocabulary. A sentence saying so keeps an operator from reading it as a verdict, and keeps abctl's rendering aligned with the vocabulary definition it mirrors.
Summary
Two non-blocking comments below. The first is the only one I would act on before merge, and only because the description names that test as one of the six: as written it cannot fail.

suggestion — this test cannot fail, so the width is not actually guarded.
I checked by breaking the thing it is meant to catch. Narrowing the column in newEventsTable():
{Title: "ACTION", Width: 4}, // was 8"tunnel" is 6 runes and now overflows — the table shifts, which is precisely the regression the description cites this test for ("a width check (ACTION is 8 columns, tunnel is 6)"). The test still passes, because actionColWidth is a second, independent 8 that the edit never touches.
The comment // {Title: "ACTION", Width: 8} shows the copy was deliberate, and it had to be: the widths are a local slice literal inside newEventsTable(), unreachable from a test. So closing this means giving the value one home:
// events_pane.go
const actionColWidth = 8
func newEventsTable() table.Model {
…
{Title: "ACTION", Width: actionColWidth},and then the test asserts against the real column rather than a transcription of it. Same three lines, but the failure now fires on the edit that causes the problem instead of on a future edit to the test.
This is worth doing rather than deleting the test, incidentally. The label is the only content on an unbridged CONNECT row — METHOD and STATUS are both empty for it — so a truncated "tunne" would take the row back to unreadable, which is the exact state this PR exists to fix. The check earns its place; it just needs to be wired to the value it checks.

nit — invs is right here, one line up, and rowAction goes and derives it again.
invs := er.invocations()
if m.hideInactive && eventInactive(invs) { … continue }
action, plugin := rowAction(er) // → eventAction(er.invocations())invocations() is not a field read — it calls allInvocations(er.event) and, for a folded tunnel, appends the tunnel's on top. So every visible row now allocates that slice twice per rebuild, and rebuildEventsTable runs on each new event and each keystroke that changes the filter or cursor. Small in absolute terms; it is the kind of thing that only becomes visible on a long session, which is also when the timeline matters most.
The reason I would still change it is legibility rather than cost. As written, nothing tells the reader that the invocations behind the hide decision and the invocations behind the headline are the same set — you have to know invocations() is pure to conclude it. Passing the value makes the relationship explicit and removes a divergence that would otherwise be silent: if anyone later filters invs at this call site (say, to honour a plugin-name filter in the hide logic), rowAction would keep using the unfiltered set and the ACTION cell would quietly disagree with the row's own visibility rule.
func rowAction(er eventRow, invs []pipeline.Invocation) (action, plugin string) {
action, plugin = eventAction(invs)
…The tests construct an eventRow and would just pass er.invocations() — a one-token change at each of the five call sites, and TestBuildEventRows_TunnelRowsAreLabelled keeps reading the same way.
…through Addresses huang195's review on rossoctl#886. Both comments were non-blocking; both were right. TestTunnelAction_FitsTheActionColumn could not fail. It declared its own actionColWidth = 8 alongside a comment transcribing the column literal, so the two 8s were independent. Verified by narrowing the real column to 4: "tunnel" is 6 runes and overflowed, and the test still passed. The width now has one home — a named constant the column literal uses — and the test asserts against that, so it fires on the edit that causes the problem rather than on a future edit to the test. Confirmed it now fails on the same narrowing. Worth keeping rather than deleting, for the reason the reviewer gives: METHOD and STATUS are both empty on an unbridged CONNECT, so a clipped "tunne" would take the row back to unreadable — the state the label exists to fix. rowAction now takes the invocations rather than deriving them again. The call site already computed them one line up for the hideInactive check, so every visible row built that slice twice per rebuild. The reason to change it is legibility over cost: as written, nothing told the reader that the invocations behind the hide decision and the invocations behind the headline are the same set, and if the call site ever filtered them the ACTION cell would keep using the unfiltered set and silently disagree with the row's own visibility rule. Also records in CLAUDE.md that abctl's ACTION column carries two values no plugin emits — "—" and now "tunnel" — so an operator does not read either as a verdict. Checked against eventAction: those are the only two, everything else is a vocabulary value, optionally shadow-suffixed.

Describe tunnel as an inactive-action label.
rowAction returns tunnelAction when eventAction(invs) returns "—". This includes empty invocations and invocations where plugins ran but only returned skip. The current text incorrectly says that no plugin ran.

Split out of #883, which was getting large. Independent of the usage work — touches only
events_pane.go.Problem
An opaque CONNECT stands in abctl's events timeline as a row of em dashes: no ACTION, no PLUGIN, no STATUS.
That is accurate — the bytes inside are TLS, so no plugin ran, no protocol was parsed and there is no status — but it reads as a request that failed or that the pipeline ignored. On a laptop install where some hosts bridge and others do not, a screen full of these looks like a regression rather than routine egress.
The rows come from clients the bridge cannot terminate for, and the log distinguishes two reasons:
bad certificateis CA distrust — the client evaluated the forged cert and rejected it.EOFis the client hanging up without an alert, the signature of certificate pinning, which no amount of CA installation fixes. Either waySkip.Add(host)makes the host a permanent passthrough for the process lifetime, so these rows are the correct and lasting outcome, not something to repair.Change
Such rows now show
tunnelin ACTION.Three cases the label deliberately does not claim:
buildEventRowsfolds it into the decrypted request, soobserve/modifystill wins.The logic lives in a
rowActionwrapper rather than inline inrebuildEventsTable, so it is testable without a terminal.Testing
Six tests: the three cases above, an empty-invocations tunnel, and a width check (
ACTIONis 8 columns,tunnelis 6).Verified against a 344-event capture from a live server — 17 rows that were blank now read
tunnel, and the 143observe/ 67modifyrows are unchanged. The 10 remaining em-dash rows are genuine passthroughs where a plugin ran but none matched, which are correctly blank.Assisted-By: Claude (Anthropic AI) noreply@anthropic.com
