poimen-memory — task board

64 tasks — 54 build tasks plus 10 composition gates, one per phase. One file per task, self-contained: inlined design facts, executable steps, acceptance criteria, a Verify section written for someone who did not build the thing, and the traps worth naming. Reading DESIGN.md is not required to do a task — it is linked as background only.

Each Verify section names the harness, the integration test with numbered assertions, the command to run, and the false pass — the shape of test that goes green while the feature is broken. Treat the false-pass list as part of the acceptance criteria, not commentary.

Ordering — declared, never derived

Phase order is the list below. Task ids are opaque and frozen.

M0.3 is M0.3 forever, in whatever phase it currently sits, because its artifacts and cross-references key on that id. New tasks take new ids rather than renumbering neighbours. This is the StepId rule applied to the board itself — a board that renumbers to reorder has the bug it warns its own users about.

No phase starts until its predecessor's gate is green. The gate task at the end of each phase is that gate: it proves the phase's parts compose and that its swappable parts are genuinely swappable. Every build task is verified alone; the gate verifies the properties no single task owns.

Two rules this board exists to protect

1. The JSONL log is authoritative; the vault and the vector index are projections. Anything that cannot be dropped and rebuilt byte-identically from the log has hidden inputs, and that is a bug. M2.8 is the gate that enforces it.

2. The update gate must discriminate, not summarize. Agent transcripts are ~43% tool results and mostly evidence-free. A gate that accepts most chunks is an expensive summarizer that will reproduce the memory-explosion failure the whole design exists to avoid. M1.8 is the gate that enforces it, and update-rate is the single number to watch.

Verification practice — script first, source second

A task is verified by running its command and reading the output, then opening the source. Reviewing the diff first is how an assertion that was quietly dropped still gets called done: the code looks right, and nothing proves the test ran.

Numbered assertion N in a Verify section is test fn aN_<slug>. The numbering is the contract — a test fn that does not exist should report missing rather than be silently absent from a green summary.

cargo test reporting ok with zero tests run is not a pass.

Progress

Source of truth is the Status field in each task file. The tables below mirror it; a status changed here and not there is a lie.

Where the line is — 2025-01-26. M0, M1, M3, M3.5 gates complete (21/21 tasks, gates green). M3.5 API layer 8/9 done (M3.5.1–8 ✅, M3.5.9 git-context pending). M3.6.1 DocCorpusSource ✅ (14 tests). Starting M4 (Skills) and M5 (Post-training) tracks. E2E/API testing deferred until after M4-M5 work. Significant early work for M3.7 and M4: mem-core/src/lesson.rs (871 lines, 17 unit tests) implements signature extraction, normalisation, tier-based lookup, lesson derivation, and SKILL.md rendering — M3.7.7, M3.7.5 are 🟡. M4.1-2 ✅ done. mem-cli/src/lessons_cmd.rs (311 lines), mem-ingest/src/derived_filter.rs (220 lines) provides working mem capture|resolve|lookup|materialize. Tests: 219 passing, 2 ignored.

M2.2 (CNPG manifest), M5.4 (vLLM+LoRA), M3.5.9 (git refs), and M6.x (agent-manager migration) are homelab/infra work independent of prior phases, can start parallel.

M6 is a different repo, not a dependency of M0-M5. It migrates github.com/Riotpiaole/agent-manager's session store (a separate Go CLI tool, unrelated to this project's own memory system) from local sqlite to its own dedicated CNPG cluster. It rides in this board because it's homelab work happening alongside M2.2/M5.4, and because the two projects' Postgres schemas landing in the same cluster around the same time need to look like siblings, not strangers — see M6.6's convention-consistency check.

1 — Read-only spine · M0.x

5.5 — Reference corpora · M3.6.x

Documentation the local models are weak at — kubectl, tea — made retrievable as level R: embedded and indexed, never evidence. Ids are M3.6.x and stay M3.6.x; the phase sits here rather than at 4.6 because M3.6.4 extends M4.2's matcher instead of duplicating it, and because skills are the better answer to the same problem and should exist first.

The load-bearing property is a negative one. Adding a corpus must not change update-rate, must not change default query output, and must not put an R node in any provenance chain. R bypasses the recurrence structurally — run_loop needs a Query and a corpus has none — not by a flag. M3.6.6 asserts M1.8's numbers are unchanged, not merely still-passing, because documentation fed to the gate would lower update-rate and make M1.8 easier to clear while the memory got worse.

5.6 — Tool context · M3.7.x

Answers "what do we already know about this failure, tool or task" over HTTP. Consumers are pi, curl, or an MCP call — nothing here executes a tool, and nothing here serves a tool catalog, because every caller already holds its own MCP schemas.

Three tiers, cheapest first. An exact hash hit on a normalised failure signature means this happened here before; a symptom-vector match means something similar did; the R corpus means nobody here has hit this, read the docs. The tier is a field in the response, because those three answers must not arrive in the same register.

The two tasks that make it work are the least obvious ones. M3.7.7 decides whether tier 1 ever fires — if normalisation leaves a timestamp in, the same failure never hashes twice and the system silently degrades to vector search. M3.7.8 closes the gap between memories written as answers and queries that arrive as stack traces. Both fail invisibly, which is why M3.7.6 ablates them rather than trusting an end-to-end green.

Ids are M3.7.x and frozen. M3.7.1 and M3.7.2 were a tool-catalog surface, deleted before implementation once the consumer was settled; their ids are retired rather than reused.

7 — agent-manager migration · M6.x

Separate repo (github.com/Riotpiaole/agent-manager, fork branch add-headless-spawn), separate cluster resource, no Rust/GRU-Mem dependency. Moves its session store off local sqlite onto a dedicated CNPG Postgres, reachable from the Mac client through a dedicated nginx route — durability-of-location, not a multi-host requirement.

M6.6	M6 composition gate	M	gate	⬜

8 — Source connectors · M7.x

Extensible multi-source ingestion. SourceConnector trait + YAML-driven registry. Adding a new document source (paperless-ngx, S3, git repo) requires implementing one trait and adding one config block — no changes to the ingest pipeline, chunking, embedding, storage, or query layers.

Document connectors produce Level R content (reference material, bypasses gated loop). Session connectors (pi, claude) produce evidence for L0/L1/L2. The connector's source_type() declares the pipeline.

Sync framework handles change detection (sha-based skip), tombstoning, drift reporting, and resumable sync for all connectors.
