Fix: Keep abctl's events when a session leaves the server's list#923esnible wants to merge 8 commits into
Conversation
abctl deleted its cached events for any session the server stopped listing, and threw the user out of the pane they were reading. The session store is in-memory and per-pod, so abctl's copy was the only copy: the events were gone for good, 2s after the proxy restarted, without the user doing anything. The single-agent shape documented at session.DefaultSessionID makes this deterministic rather than occasional. Nearly everything lands in one "default" bucket, /v1/sessions returns an empty list after a restart until traffic arrives, and an empty list is not an error — so it arrived as a normal sessionsLoadedMsg, matched nothing, and wiped the one bucket the user had. Time-based expiry was never involved: session.ttl defaults to never and the reaper does not even start when ttl <= 0. The server list is now authoritative about what is LIVE, not about what is viewable. Sessions that leave it are tombstoned, not deleted: the events stay viewable, the pane is never changed underneath the user, and a banner names the mechanism that ended the live feed (restart vs eviction) rather than blaming "expiry". Tombstoned sessions stay listed in the sessions table, marked gone, so retained events remain reachable. Cleanup moves to the moment the user selects a *different* session, the one reliable signal that the old events stopped mattering. A rekey — the case the old delete was actually written for — now migrates the cached events and the selection to the new id instead of dropping them. Two adjacent bugs found while tracing this: - The footer's "drops: N" indicator was fed by m.drops, which was never incremented anywhere, so it read "drops: 0" unconditionally. The store does drop events when a subscriber's channel fills but reports it only to the server's own slog, so an honest counter needs the count on the wire first. Removed until then: an indicator hardcoded to reassure is worse than no indicator, especially during this exact investigation. - maxEventsPerSession claimed to match the server's default max_events. It is 1000 against 500. Corrected the comment rather than the value — holding more than the server is the useful direction now that abctl's buffer can be the only surviving copy. backToPodsPane did not clear colPicker, the same latent bug that TestColumnPicker_DoesNotReturnAfterAnAsyncPaneChange was written to prevent, on the async pane change that survives this change. Fixed, and that test re-pointed at it since the transition it used to drive is deliberately gone.

Review feedback, all four points: - Document that enter on the sessions pane is the SOLE release point for tombstoned events, so a user who never drills into another session keeps all N for the process lifetime. Bounded in size, not in time, and deliberately so: a timer or count sweep would be another mechanism deleting events out from under someone who stepped away, which is the failure this change exists to remove. backToPodsPane already nils the map, so it needs nothing. - Note the ordering dependency in the rekey detection: soleNewSession compares against m.sessions, so reconcileGone must run before that field is replaced. Commented on both sides and pinned by a test that drives Update, since a reorder is otherwise silent — no id looks new, so rekeys just stop migrating and leave a stale duplicate bucket. - Tighten the tombstone-row count assertion: exact match instead of strings.Contains, which "13" and "30" would also satisfy. - Reword the empty-list banner. An empty list is strong but not conclusive evidence of a restart: eviction cannot produce one (it fires only when the count exceeds max_sessions), but an explicit session.ttl sweep could. Now reads "server has no sessions (proxy restarted, or all aged out)" rather than asserting a cause it cannot verify without a boot id on the wire. styleWarn is still used twice in footerView ([paused] and the connection state), so removing the drops indicator left no unused import — Go CI was right.

Addressed in 29f1263. 1 — 2 — rekey ordering dependency (nit). Good catch, and load-bearing enough that I did not want to leave it as prose only. Commented on both sides, plus Design note — false "restarted" on an idle proxy. You're right, and it narrowed usefully: eviction cannot empty the list (it fires only when the count exceeds Filed both follow-ups: #924 (drop count on the wire) and #925 (boot/instance id). #925 notes the inverse case an empty-list check misses entirely — a restart whose store has already been repopulated by new traffic.

The core fix is well-reasoned and the 8 new tests cover the state machine thoroughly, including the ordering dependency that rekey detection rests on. One must-fix: the new gone marker is ANSI-styled inside a bubbles table cell, which garbles the label and leaks an unterminated escape in any real terminal — invisible to CI because lipgloss emits no escapes without a TTY.
Every factual claim in the PR verified against upstream/main: max_events default 500, max_sessions default 100, ttl default never — so the maxEventsPerSession = 1000 comment correction is accurate.
One note that needs no change here: the body says "Time-based expiry was never involved — session.ttl defaults to never." That is only true since #904, which merged one day before this PR. When #870 was filed the default was 30m, so TTL plausibly was involved in the reporter's original experience. The banner wording ("or all aged out") and gone.go's comments already cover that path — just worth knowing when closing #870.

must-fix — an ANSI-styled string in a table.Row cell renders as gon… and leaks an unterminated SGR sequence.
bubbles v1.0.0 renderRow truncates every cell with runewidth.Truncate(value, col.Width, "…"), and runewidth is not ANSI-aware. The ACTIVE column is width 8 and is never resized — newSessionsTable sets it and nothing calls SetColumns on sessionsTbl anywhere in tui/.
Reproduced against the pinned deps (bubbles v1.0.0, lipgloss v1.1.0, go-runewidth v0.0.24):
styleWarn.Render("gone") = "\x1b[93mgone\x1b[0m" runewidth=11 (not 4)
runewidth.Truncate(cell, 8, "…") = "\x1b[93mgon…"
Two visible defects on the tombstone row:
- The label reads
gon…instead ofgone. - The closing
\x1b[0mis stripped, so the warn colour bleeds into everything rendered after that cell.
CI cannot catch this. With no TTY lipgloss's profile is Ascii, so Render("gone") returns plain "gone" (width 4, truncation is a no-op) — I confirmed both the TTY and no-TTY cases. TestGoneSessionStaysInSessionsTable also asserts only on Rows() data (r[0], r[2]), never on View().
Fix: pass plain "gone", matching the unstyled "●" in the live-row branch just above. bubbles v1.0.0 has no per-cell styling, so a styled cell is not viable at any column width. Worth adding a test that renders View() under a forced colour profile and asserts the cell survives intact — that is the gap that let this through.

suggestion — this delete is unconditional, so it also runs when the migration above was skipped:
if _, exists := m.events[newID]; !exists {
...
m.events[newID] = events
}
delete(m.events, oldID) // ← runs even when the move didn't happenWhen newID is already cached, the default bucket is discarded with no migration and no tombstone — the one deletion path this PR otherwise forbids. The doc comment justifies it by way of the server's Rekey being a no-op when newID exists, but abctl's cache is not the server's store, and that is exactly the distinction the rest of this file is careful to draw.
Reachability is contrived — it needs the server list to flip default→ctx-42 while abctl already holds ctx-42 events, and handleStreamEvent normally inserts a stub summary that makes soleNewSession return "". But the exists guard is here because the case was considered possible, and the consequence is precisely the unrecoverable loss this file exists to remove.
Moving delete(m.events, oldID) inside the if is sufficient: the loop in reconcileGone then tombstones oldID on its own, so the events stay viewable under the old id.

nit — this loop keys off m.events, which can hold a key with an empty slice: snapshotLoadedMsg does m.events[msg.id] = trim(msg.events, maxEventsPerSession) unconditionally, so drilling into a session that has no events yet creates the key regardless of what trim returns.
Such an id then gets a tombstone and renders as id — 0 — gone in the sessions table: a row advertising retained events that do not exist, held for the process lifetime until the user selects a different session.
A if len(m.events[id]) == 0 { continue } guard follows this file's own rationale — the tombstone is justified by abctl holding the only copy, and here there is no copy to hold.

Duplicate — accidental re-submission of the same review. See the first review on this PR for the findings.
Review from huang195, all three findings reproduced and fixed.
must-fix — the ANSI-styled "gone" cell. bubbles v1.0.0 renderRow does
runewidth.Truncate(value, col.Width, "…") BEFORE styling, and runewidth
is not ANSI-aware. Reproduced against the pinned deps: styleWarn.Render
("gone") is "\x1b[93mgone\x1b[0m", which runewidth measures as 11
against the ACTIVE column's width of 8, so Truncate returns
"\x1b[93mgon…" — the label reads "gon…" and the closing reset is
stripped, bleeding the colour into every later cell. bubbles v1.0.0 has
no per-cell styling, so no column width makes a styled cell viable. Now
plain "gone", matching the unstyled "●" beside it.
CI could not see it: with no TTY lipgloss's profile is Ascii, Render
returns bare "gone", and truncation is a no-op. Every other test here
asserts on Rows() data, never on View(). Closed that gap with a test
that forces a colour profile, renders View(), and asserts the label
survives — verified to fail against the styled cell.
suggestion — migrateSession deleted the source unconditionally, so when
newID was already cached the default bucket was discarded with no
migration and no tombstone. Reachability is contrived, but it was the
one remaining unrecoverable-deletion path in a file that exists to
remove them. Now returns early, leaving reconcileGone to tombstone the
source so the events stay viewable.
nit — the tombstone loop keyed off m.events, which can hold an empty
slice: snapshotLoadedMsg assigns m.events[id] unconditionally, so
drilling into a session with no events yet creates the key. That
rendered "id — 0 — gone", advertising retained events that do not
exist. Skipped when there is nothing cached, per this file's own
rationale — the tombstone is justified by holding the only copy.
Also narrowed the rekey detection (CodeRabbit, same lines): "default
vanished and one unfamiliar id appeared" is equally what an eviction of
default plus an unrelated new session looks like, and migrating then
files events under a session they never belonged to. Now also requires
the list to be the same size and to have contained "default". Neither
is proof, so the failure mode is a missed migration rather than a wrong
one — declining leaves the events tombstoned under the old id.
On the PR body's "time-based expiry was never involved": correct as of
today but not when rossoctl#870 was filed, since the ttl default became never
only in rossoctl#904. Noted for whoever closes rossoctl#870; no code change.

The render test added in 3c12429 imports github.com/muesli/termenv to force a colour profile, which makes it a direct dependency of the abctl module. go.mod still listed it as indirect, so "Verify module graph is tidy" failed. Local `go test` did not catch it: the go.work workspace resolves the import regardless of how go.mod classifies it.

forgetGoneExcept mutates m.gone, and the sessions table renders its tombstone rows from that map, but the enter handler rebuilt only the events table. A freed tombstone therefore kept its row until the next 2s refresh. The stale row is not merely cosmetic: it still shows the event count from before the cache was dropped, so it reads "b — 3 — gone" while m.events["b"] holds 0. Backing out and selecting it lands on an empty events pane and flashes a 404 from the snapshot fetch. Reported as the :418 guard being unable to fire because "the tombstone was just deleted". That is not quite it — forgetGoneExcept skips the id it is passed, so m.gone[keep] survives and the guard still suppresses the fetch for the session being opened. Verified. The 404 belongs to the OTHER id, whose tombstone was freed: selecting it later finds no tombstone, so the guard correctly declines to fire and the fetch goes out to a session the server does not have. Same visible defect, different mechanism, and the fix is the same rebuild either way. Test drives the real key handler rather than calling rebuildSessionsTable itself, so deleting the fix fails it — confirmed.

Focused fix, and the three findings from my earlier pass are all genuinely closed: the ACTIVE cell is plain text now with an accurate comment, migrateSession early-returns instead of deleting unconditionally, and empty cache keys are skipped — each with a test, including TestGoneMarker_SurvivesRenderingUnderColor forcing a colour profile, which is the right fix for the CI-can't-see-it gap.
One new must-fix: the rekey/eviction discrimination has a hole that opens at max_sessions capacity, and the code comment asserts it's closed. CreatedAt is already on the wire and closes it properly.
Checked and cleared: termenv indirect→direct is correct (test import) and stays at the existing v0.16.0, so no new supply-chain surface. Every README retention claim verifies against main — ttl defaults to never (store.go:503), max_sessions 100, max_events 500, eviction on > — and the maxEventsPerSession = 1000 comment correction is accurate (2× the server's 500). goneBannerHeight's reservation matches the single-line render, including the width <= 0 fallback.

must-fix — the three guards do not separate a rekey from an eviction, and the comment above claims a safety property the code does not have:
Neither is proof (the server does not tell us), which is why the failure mode is now merely a missed migration rather than a wrong one
A wrong migration is still reachable, and not in a contrived way — it is the steady state at max_sessions. Append evicts when the count exceeds the cap (store.go:231) and evictOldestLocked (store.go:473-493) deletes exactly one entry. So at capacity: session #101 arrives → one evicted → list is back to 100. One id vanished, one appeared, length unchanged.
If the evicted one is default (it is skipped only when it is activeID, so a stale default is the prime candidate), all three guards pass — default cached ✓, absent from serverIDs ✓, len(summaries) == len(m.sessions) ✓, hasSession(prev, default) ✓ — and soleNewSession returns the genuinely-new unrelated id. migrateSession then rewrites events[i].SessionID and files default's history under a session it never belonged to. That is the exact outcome the comment says is prevented, in the scenario the new banner names ("evicted").
The server does tell us, though — CreatedAt is the discriminator. Store.Rekey renames in place on the same *entry (store.go:442-444), so a rekeyed session carries default's original CreatedAt; a newly created session gets CreatedAt: now (store.go:201). It is on the wire (SessionSummary.CreatedAt, json:"createdAt") and apiclient.ListSessions decodes into session.SessionSummary, so both the previous list (m.sessions) and summaries carry it. Gating the migration on the new id's CreatedAt equalling the previous default summary's CreatedAt turns this into a genuine proof, and makes the length/hasSession heuristics redundant. (Use .Equal() rather than == — both sides come back through JSON, so neither carries a monotonic reading, but .Equal() is the correct comparison regardless.)
If you would rather not migrate at all, that is equally defensible — tombstoning default costs only a duplicate bucket. What I do not think should ship is the current combination: a heuristic that fails in the common capacity case, plus a comment asserting it cannot.

suggestion — this test does not exercise migrateSession's declined path. With m.sessions holding two entries and summaries holding one, len(summaries) == len(m.sessions) is 1 == 2 → false, so the guard in reconcileGone short-circuits and migrateSession is never called. The m.events["ctx-42"] setup that makes the migration "declined" never matters — this is really a second copy of TestEvictionPlusNewSession_IsNotTreatedAsRekey, passing via the length guard.
So the PR body's "each verified to fail against the code it guards" does not hold here: delete the early return from migrateSession and this test still passes. (TestMigrateDeclined_DoesNotDropTheSource does cover it by calling migrateSession directly, so the behaviour is not unguarded — just not integration-tested.)
Dropping {ID: "ctx-42"} from this line reaches the real path: previous [default], new [ctx-42], lengths equal, ctx-42 already cached → migrateSession is entered and returns early.

nit — while you are in these lines: the sessions table has five columns — newSessionsTable sets ID, UPDATED, EVENTS, TOKENS, ACTIVE — but this bullet lists four, and the diagram at line 11 has no TOKENS header either. Pre-existing drift, but the diagram now grows a gone row that readers will line up against the real UI, and the new tombstone row does populate TOKENS via sessionTokens(0, cached).
The list-shape heuristics did not separate a rekey from an eviction, and the comment above them asserted a safety property the code lacked. Reproduced before changing anything. Append evicts only when the count EXCEEDS max_sessions and evictOldestLocked removes exactly one entry, so at capacity session rossoctl#101 arriving means one id vanishes and one appears with the length unchanged. A stale "default" is the prime candidate (it is spared only while it is activeID). All three guards then passed and default's 3 events were filed under an unrelated session, SessionID rewritten — the exact outcome the comment claimed was prevented, in the case the banner calls "evicted". Not contrived: it is the steady state at capacity. CreatedAt is a real discriminator, as the reviewer noted. Store.Rekey renames in place on the same *entry, so a rekeyed session reports default's original CreatedAt, while a fresh session gets CreatedAt: now. Verified end to end rather than by reading: driving the real store through the JSON encoder and decoding as apiclient does confirms the rekeyed id preserves the timestamp and a new id does not. rekeyedTo now gates on that equality, which makes the length and prior-membership checks redundant — both removed along with soleNewSession/hasSession. The .Equal() detail is load-bearing and also verified: after a JSON round trip, == on the same instant returns FALSE while .Equal() returns true. Using == would have silently disabled migration rather than failing loudly. Covered by a test that re-parses an RFC3339 timestamp. Two existing rekey tests were under-specifying the store: they built summaries with no CreatedAt, which no real rekey produces. Updated to carry it, so they model what Rekey actually does.

TestMigrateDeclined_TombstonesTheSource passed without exercising migrateSession at all: "ctx-42" was in the PREVIOUS list, so it was not an unseen id, rekeyedTo skipped it, and the migration was never attempted. The m.events["ctx-42"] setup that makes the migration "declined" never mattered — it was a second copy of TestEvictionPlusNewSession_IsNotTreatedAsRekey. Verified rather than assumed, twice. Disabling migrateSession's early return left the test PASSING, which is the claim it exists to check. Instrumenting migrateSession with a call counter then showed why: entered 0 times under that setup. The same instrumentation corrected the suggested fix. Dropping "ctx-42" from the previous list alone still gives 0 entries — the gate now needs a matching CreatedAt (1dc35ee, which landed after the suggestion was written). With both, the counter reads 1 and the declined path is real. Now fails when the early return is removed. Also asserts the existing target cache is not clobbered, which only became observable once the path was reached. The direct unit test TestMigrateDeclined_DoesNotDropTheSource stays: one calls migrateSession directly, the other proves reconcileGone routes into it, and both catch the removal.

The sessions table has five columns (ID, UPDATED, EVENTS, TOKENS,
ACTIVE) but the README's bullet listed four and the diagram had no TOKENS
header. Pre-existing drift, and this PR made it worse by adding a `gone`
row readers will line up against the real UI.
Transcribed the diagram from the actual rendered table rather than
hand-editing it: a throwaway test printed sessionsTbl.View() with two
live sessions and a tombstone, so the header and the sample values are
what abctl really prints, formatCount's thousands separator included.
That also checked the reviewer's parenthetical. sessionTokens(0, cached)
does populate the column for a tombstone — it sums the cached response
events and falls back to "—" only at zero, so a tombstone with inference
data shows a real number (verified: row 2 = {default, —, 8, 320, gone}).
The diagram now shows that rather than a blank.
Two tests pin it: one asserts the column titles against the documented
set and names the README in its failure message, the other asserts a
tombstone row's TOKENS cell comes from the cache. Verified the first
catches a dropped column.
Also squared up the diagram's box: two lines were one column wider than
the other seven, which predates this PR.

Suppress QF1009 for this intentional struct comparison.
This test needs == to confirm that the representations differ before it verifies instant equality with Equal. Do not replace this comparison with Equal. Add a targeted nolint directive with this reason.

Add a regression test for stream-first rekey handling.
When handleStreamEvent receives an unknown session ID, it appends that ID to m.sessions. The next sessionsLoadedMsg passes it to rekeyedTo as an already-seen ID, so migration from default is skipped. The old events remain under the tombstoned default ID, and selection does not move to the new ID. Test this sequence explicitly.

The CreatedAt rewrite closes my previous must-fix properly, and I verified the whole chain against main rather than taking the comment's word for it: Store.Rekey renames in place on the same *entry (store.go:442-444) so CreatedAt survives the rename; ListSessions copies sess.CreatedAt into the summary (store.go:359); the field carries the createdAt JSON tag (store.go:338); sessionapi.handleList encodes []session.SessionSummary whole (server.go:301-308); and apiclient.ListSessions decodes into that same type (client.go:54-62). So the timestamp really is on the wire on both sides, and TestEvictionAtCapacity_DoesNotMisMigrate reproduces the capacity case that defeated the list-shape heuristic. Dropping the length and prior-membership guards is right — they only ever narrowed a guess, and the proof does not need them.
The other two items from my last pass are closed too: TestMigrateDeclined_TombstonesTheSource now reaches migrateSession for real and additionally asserts the target cache was not clobbered, and the README's column list and diagram both match newSessionsTable, pinned by TestSessionsTable_ColumnsMatchDocumentedSet. The diagram is now uniformly 66 columns wide, and formatCount does render 320 and 1,500 as shown.
One new must-fix, and it comes from this PR's own new line rather than from the CreatedAt work: handleStreamEvent now clears the tombstone the instant an event arrives, which removes the guard that was keeping snapshotLoadedMsg's unconditional overwrite away from retained events. Details inline, along with a case where the new proof reads a timestamp abctl invented itself.

must-fix — clearing the tombstone here removes the only thing protecting the retained events from being overwritten.
snapshotLoadedMsg replaces the bucket outright — m.events[msg.id] = trim(msg.events, maxEventsPerSession) at app.go:730 — and the only reason Enter is safe on a session whose events exist nowhere else is the gone guard at keys.go:426, which returns before snapshotCmd. This line deletes the tombstone as soon as one event arrives, so that guard stops applying while the cache still holds events the server no longer has.
The single-agent shape this PR is written for reaches it by ordinary navigation:
- proxy restarts → list empty →
defaulttombstoned, events kept (the fix working) - user backs out to the sessions pane
- traffic resumes → the first streamed event clears
m.gone["default"]here - user presses
Enterondefault→ keys.go:426 no longer matches →snapshotCmd→ the server's post-restart snapshot replaces the bucket
The pre-restart events are then gone from the only place they existed — the outcome reconcileGone's own doc comment exists to prevent ("Deleting is irreversible. The session store is in-memory and per-pod, so once abctl frees its copy the events exist nowhere"). The overwrite at app.go:730 predates this PR, but before it nothing was lost because nothing was retained; the retention promise is new, and this is the path that breaks it.
Untangling the tombstone from the retention marker is enough: keep a separate retained set (marked when tombstoning, cleared in forgetGoneExcept) and have the snapshotLoadedMsg case append rather than assign for those ids — SessionEvent.At gives a cheap high-water mark to filter the server's list against. Clearing m.gone here so the banner drops immediately stays correct.

suggestion — the proof can read a timestamp abctl invented itself, so a rekey is still declined in the ordinary first-turn race.
handleStreamEvent synthesizes a summary for any id it sees on the stream that is not yet in m.sessions, stamped CreatedAt: e.At (app.go:1100). e.At is set by the listener at time.Now() when the event is built (e.g. forwardproxy/server.go:346), while the entry's CreatedAt is a different time.Now() taken inside Store.Append — the store never copies one into the other, so they are never equal.
So when the stream delivers default's first event before any /v1/sessions poll has seen it, prev's default carries a fabricated CreatedAt, the comparison at line 170 fails against the rekeyed id's real one, and rekeyedTo returns "". The window is the gap between default's first event and the rekey (which fires when the backend response reveals the contextId), against a 2s refreshInterval — so a sub-2s first turn hits it and a slower one does not. The old heuristic was immune because it only asked whether the id was present, never what its timestamp was.
The failure direction is still the safe one (missed migration, stale duplicate bucket, events retained), so this is not a blocker. But it is a third way rekeys silently stop migrating and the comment above names only the ordering dependency, and none of the four rekey tests reach it — they all build m.sessions by hand with a store-shaped CreatedAt.
Cheapest fix is to make the stub short-lived: have handleStreamEvent also kick a sessions refresh when it invents a summary, so the store's real CreatedAt lands on the next round trip instead of up to 2s later. If that is not worth it, say in this comment that a stream-first session cannot be proven — leaving the stub's CreatedAt zero would take the same early return, just honestly.

nit — this skip cannot fire, and if it ever did the test would pass while asserting nothing.
base comes from time.Now(), so it carries a monotonic reading and time.Local; viaJSON comes from time.Parse, so it has neither. == compares those fields, so it is false on every platform Go supports. Making the branch t.Fatal instead of t.Skip keeps the test honest either way — a conditional skip is the shape that quietly stops guarding something later.

Two must-fixes from review, both reproduced before changing anything. The release loop deleted every cached session except the one being opened, cached-only ones included. Since their copy is the only copy, that was the same unrecoverable loss rossoctl#870 is about — reintroduced by the release logic meant to bound the cache. Verified with three cached-only sessions after a restart: opening one left the other two at 0 events. Release is now scoped to sessions the server still lists. Those are recoverable via snapshotCmd, so dropping them costs nothing; a cached-only session is kept. After a restart every previously-visited session is cached-only, which is exactly when the old behaviour was most destructive. snapshotCmd was also unconditional, so opening a cached-only row fired a GetSession that 404s, and errMsg flashes that over the events this change preserves. Verified, and skipped now when the id is not live. rossoctl#923 had this guard; it was lost with the gone map it keyed off. Consequence, measured rather than asserted: cached-only sessions are never released while abctl runs, so the cache grows one entry per restart the user visited a session across. At ~165 bytes per event and 1000 events per session that is ~161 KB per session, a few MB for a long session — noted in the comment. The alternative is deleting the only copy of what someone is reading. Three tests added, each verified to fail against the pre-fix code with the symptoms described: cached-only sessions survive the release, opening one fires no snapshot, and a live one still does. On the third review point: TestPickingAnotherSession_ReleasesThePrevious does set both ids live, so it does exercise the live-release path and still passes. What it never covered was the cached-only case, which the new tests do. Refs rossoctl#870 Assisted-By: Claude (Anthropic AI) <noreply@anthropic.com> Signed-off-by: Ed Snible <snible@us.ibm.com>

Fixes #870.
abctldeleted its own cached events for any session the server stopped listing, and threw the user out of the pane they were reading. The store is in-memory and per-pod, so abctl's copy was the only copy.Deterministic for the single-agent shape where nearly everything is one
defaultbucket: after a proxy restart/v1/sessionsreturns an empty list (not an error), so it arrived as a normalsessionsLoadedMsg, matched nothing, and wiped the only bucket 2s later.On the root cause of #870, corrected. An earlier revision of this body said
"time-based expiry was never involved —
session.ttldefaults to never." That istrue of
maintoday but not of the code the reporter was running. Theneverdefault arrived in #904 (
caf38e4e, merged 2026-09-08); before that the defaultwas
30m. #870 was filed 2026-09-04, so at the time the reporter lost the eventsthey were analyzing, an idle session really could age out on its own after 30
minutes — which fits their description of being interrupted and coming back.
So TTL was plausibly a genuine cause of the original report, and the issue's first
hypothesis ("did Cortex expire them because they were too old?") was reasonable
rather than mistaken. #904 removed that cause; this PR fixes a second, independent
one that #904 did not touch, and which is what remains reproducible on current
main:abctldeleting its own cache. Both were needed — after #904, a restart oran eviction still cost the user their events, because the deletion was client-side.
Worth knowing when closing #870: the fix is spread across #904 and this PR, and the
reporter's diagnosis was not wrong for their build.
The server list is now authoritative about what is live, not what is viewable:
Tombstoned sessions stay listed as
goneso retained events remain reachable; the pane is never changed underneath the user.Two adjacent bugs found while tracing this, both separable:
drops: Nwas fed bym.drops, never incremented anywhere, so it readdrops: 0unconditionally. Removed — an honest counter needs the drop count on the SSE wire first (the server logs it only to its own slog).maxEventsPerSessionclaimed to match the server'smax_events; it is 1000 against 500. Corrected the comment, kept the value.backToPodsPanedid not clearcolPicker— the same latent bugTestColumnPicker_DoesNotReturnAfterAnAsyncPaneChangeguards, on the async transition that survives this change. Fixed, and that test re-pointed at it.Build, vet,
-raceand the fullabctlsuite pass. 15 new tests, each verified tofail against the code it guards — including the render test, which is vacuous
without a forced colour profile since CI has no TTY.
Two follow-ups this PR deliberately leaves out of scope, both needing a server-side
change: putting the SSE drop count on the wire (so the removed footer indicator can
return with a real number), and a boot/instance id so
abctlcan detect a restartdirectly instead of inferring it from an empty session list. The banner wording is
hedged accordingly until the latter exists.
