← Session 17 — Lean tier (i): elementary proofs (after crash)
thinking (1490 chars)
Interesting — the file now contains `bern_term_nonneg` and `bern_term_upper` helpers (proved, tagged [PROVED session 011]) that I didn't write. Someone else (another agent instance? Possibly a parallel session or the crashed session's leftover process?) is editing the same file concurrently. This is a collision risk: my Edit failed because the file changed under me.
The helpers present: bern_term_nonneg, bern_term_upper (different formulation than mine — the upper bound is a DIFFERENT, stronger statement: h⁺(m) ≤ n(n−1)/(2m²), without the 1 ≤ n hypothesis, using a cleverer route). Good — these can serve my purpose:
- nonneg: matches my sInfTerm_nonneg ✓
- upper: h⁺ ≤ n(n−1)/(2m²) — summability comparison works with this too ✓
But wait — did a parallel agent write these? The user said the system crashed. Maybe a previous crashed-session agent process is still alive and editing? That's concerning — concurrent edits could clobber each other. Let me check git status and whether there are stray processes.
Actually more likely: the "crash" killed a session where an agent had already started this task and written those lemmas, and the file on disk has them (uncommitted). My earlier read of the file (at conversation start) showed the version WITHOUT bern_term_* — so the file changed between my first read and now. Something modified it in the last few minutes. Possibly another Nguyen CLI instance is running.
I should check with the user? First check git status/processes.
The file now contains two new proved helper lemmas (`bern_term_nonneg`, `bern_term_upper`) that neither of us wrote in this session — something modified it in the last few minutes. Let me check whether another agent process is still alive from before your crash.
