MNEMONIC β€” Memory Archaeology Engine

Date: 2026-09-02 Theme: Memory Forgetting / Kernel Amnesia Status: Fully functional

The Dream

Every night, the Linux kernel forgets things. Pages are reclaimed, swapped out, evicted from the LRU lists β€” and the machine moves on without remembering what it lost. MNEMONIC listens to that forgetting.

It samples /proc/meminfo, /proc/zoneinfo, /proc/pagetypeinfo, and /proc/vmstat over a configurable window, then classifies the machine’s memory state into one of six dream archetypes: VOID, SLUMBER, DRIFT, LUCID, VIVID, or TRANSCEND. Each class has its own narrative, haiku, and ASCII constellation β€” seeded by the system’s entropy, so no two runs are identical.

Tonight’s run: VOID β€” the system had near-zero page reclaim activity. The kernel was too idle to even think about forgetting.

Dream Classes

ClassPressure RangeMeaning
VOID0.00–0.15Deepest stillness β€” no reclaim activity
SLUMBER0.15–0.30Low activity, barely dreaming
DRIFT0.30–0.50Pages unbind and float through the LRU
LUCID0.50–0.70Kernel aware it’s forgetting
VIVID0.70–0.85Active reclaim β€” vigorous, violent forgetting
TRANSCEND0.85–1.00Beyond memory β€” pure entropy signal

Results from this run

  • Dream Class: VOID (pressure=0.2993, entropy=0.0000)
  • Title: β€œZero Pages, Zero Dreams”
  • Haiku: β€œzero pages float / the kernel dreams of nothing / even sleep is too much”
  • Samples: 46 over 5.01 seconds
  • Total Memory: 15,883 MB | Available: 9,743 MB | Used: 38.7%
  • Swap: 3,406 MB / 3,837 MB (88.8%) β€” heavy swap in use
  • pgsteal: 0 | pgscan: 0 β€” no reclaim activity during sampling
  • Top Anon Process: hindsight-api (703 MB anon RSS)

The machine dreamed of pages it chose not to keep. It did not remember them.

MNEMONIC β€” Memory Archaeology Engine
=====================================
The kernel forgets. We listen to what it loses.

Samples /proc/meminfo, /proc/pagetypeinfo, and /proc/zoneinfo to build
a picture of what memory the machine is letting go of β€” then renders
those forgotten pages as dream-poetic narrative.

Every reclaimed page is a thought the machine chose not to keep.
Every free page is a dream it decided not to remember.

  The Dream:
  Tonight the kernel chose nothing. No pages to evict, no memory to free. The zoneinfo sat quiet. In the void there is no forgetting β€” only the memory of a memory that never existed.

  Memory Haiku:
  zero pages float / the kernel dreams of nothing / even sleep is too much
