Documentation Overview

PPM β€” Python Package Manager

pypm packaging CLI with shared PMLL memory + Q-promise. Sibling: drQedwards/pmll.

CI License Version npm Sponsor

Live Stellar pmll-anchor IDs: docs/STELLAR.md Β· skills: SKILL.md Β· promises: Q_promise_lib/README.md.

TL;DR: PPM packages Python (C CLI). Shared PMLL owns memory/state (memory_silo_t, exact peek + semantic peek_semantic, SAT bridge, init_pml). Q-promise owns temporal/control-flow (qpromise_*, libqpromise.so) β€” it does not replace the silo. Optional Stellar commitments hash off-chain CodeworkPayloads into 32-byte digests via pmll-anchor (ABI: init/store/get/bump). Companion packaging CLI + MCP memory server live in-tree.

PMLL provides durable structured memory for agent workflows, alongside a PPM packaging CLI (hermetic bundles, plugins, signing) and the PMLL Memory MCP server. Long-term graph tools adapt Context+.

Layers (post-merge)

Two complementary layers β€” not substitutes for each other:

LayerOwnsKey surface
PMLLDurable memory / statememory_silo_t, peek / peek_semantic, silo_set, SAT bridge, init_pml
Q-promiseTemporal / control-flowqpromise_* API, libqpromise.so, deferred qpromise_drain()

Q-promise does not replace the silo. A promise may reference a memory key (and optional SAT state id); results are committed back with silo_set / qpromise_resolve_commit.

Intended loop

Code
retrieve (peek / peek_semantic)
  β†’ compute / request work
  β†’ promise PENDING
  β†’ resolve / reject (optionally resolve_commit β†’ silo)
  β†’ continuation (then / catch / finally via qpromise_drain)
  β†’ memory update
  β†’ retrieve again

Thread safety: the C Q-promise drain is single-threaded. Continuations run only during qpromise_drain() on the calling thread; callers must externally serialize access. Details: Q_promise_lib/README.md.

C core (PMLL)

Headers: PMLL.h Β· implementation: PMLL.c

SymbolRole
memory_silo_tAssociative/semantic silo: tree, slots[], embed_dim (PMLL_EMBED_DIM=32), slot_count
silo_slot_tkey, content, embedding, resolved
init_silo / free_silo / silo_setAllocate, free, write key/content + embedding
peekExact key, else index
peek_semanticCosine β‰₯ min_sim over embeddings (silo_embed_text, silo_cosine_similarity)
init_pmlSets every assignment[i] = -1 (undecided)
check_conflictTreats -1 as undecided (not sticky false from zero-fill)
sat_bridge_*Map 3SAT tokens β†’ associative string literals in the silo

Q-promise library

Build / test / API: Q_promise_lib/README.md (authoritative). Public symbols are qpromise_*; shared object is libqpromise.so. The old prototype (QMemNode / q_mem_* / memory-chain walker) is removed; Q_promises.h is a compatibility include redirecting to qpromise.h.
