When a user's tmux session dies (mRiver reboot, OOM, manual kill,
container restart) the next turn used to wake claude with NO prior
context — the persona had to derive everything from the new turn
alone. Now: when the Go side detects a fresh pane, it pulls the last
N exchanges from paliad.paliadin_turns and prepends them as a
[primer …][/primer] block to the next user envelope.
Format SKILL.md parses (single-line, control-chars stripped):
[PALIADIN:<turn_id>] [primer last=N] U: … \n A: … \n … [/primer] [ctx …] <Frage>
Detection paths:
- Local (LocalPaliadinService): ensurePane now returns
(target, isFresh, err). isFresh is true when no prior
@paliadin-scope=chat window existed and we created one. RunTurn
passes that into buildPrimerIfFresh.
- Remote (RemotePaliadinService): can't see across the SSH boundary
to know the pane's true freshness, so we approximate with a
per-(session, Go-process) "primed" cache. First turn after
process-start, ResetSession, or healthGate failure rebuilds the
primer; subsequent turns skip it. ResetSession + healthGate failure
both call clearPrimed(session) explicitly.
paliadinDB.buildPrimerIfFresh assembles the block:
- Reads the last MaxPrimerTurns=5 exchanges from
ListHistoryForSession (Slice F).
- truncateForPrimer normalises each side (drops \r\n, collapses
whitespace, caps at MaxPrimerCharsPerSide=600 with …).
- Returns "" silently when isFresh=false, no SessionID, no prior
history, or DB error — the user's actual question still lands; we
only lose the recap.
SKILL.md (~/.claude/skills/paliadin/SKILL.md, refreshed via
scripts/install-paliadin-skill) gets a new "Crash-recovery primer"
section above the context-envelope block. Five behaviour rules:
1. Don't re-execute prior tool calls (audit log already has them).
2. Use the primer for thread continuity, not as a data source.
Re-call tools for fresh facts.
3. Truncated lines (ending in …) are partial — paraphrase rather
than quote.
4. No primer at all = normal case (existing pane, history is in
tmux memory). Behave as before.
5. Acknowledge sparingly — usually just answer the actual question
with the recap as silent context.
New test TestTruncateForPrimer pins the per-side truncation contract
(no \r\n leaks, repeated spaces collapsed, ellipsis on oversized
input, short input untouched). go test green.
