From 391ef44d2d588c1df95dbf6c4d5869843a08561f Mon Sep 17 00:00:00 2001 From: Ayla Croft Date: Sun, 20 Sep 2026 20:37:46 -0400 Subject: [PATCH 1/8] docs(s030): G1 plan with the tier budgets measured, the default SOUL, and the slice opens ROADMAP row 030 to in_progress. NOTES.md records the default SOUL's 464 tokens and the untrusted rule's 85 against the stable tier's 800, sets the volatile tier to the byte budget's 2,731 tokens rounded to 2,800 so the two budgets agree, then the eight-line build plan, the one-item manual queue and four deviations stated before any code. priv/personas/default/SOUL.md written. plan_check: PASS.

Test: the unique key; the log grows with + every write. +2. `Trinity.Personas` (a context over the `Sessions.Persona` schema, which stays where 010 put it: deviation a): + `list/0`, `get/1`, `create/1`, `update/2`, `seed_default/0` reading `priv/personas/default/SOUL.md` into the + default persona when its soul is empty, and the default persona's `settings["permissions"]["memory"]` set to + `"allow"` (the persona-level rule). `Sessions.default_persona/0` calls it. Test AC1: a fresh database seeds the + default persona with the file's soul and a session's system prompt starts with it. +3. `Trinity.Memory.AlwaysOn`: `snapshot(session_id | {persona_id, session_id})` renders the deterministic block + (tier, then key, sorted; `profile` first, then `always_on`) over the session's scope chain + `[session:, persona:, global]`; `write/1`, `replace/1`, `remove/1`, `promote/2`, `list/1`, every + change a `memory_changes` row. `Trinity.Memory.Budget`: bytes of profile + always_on per persona against + `config :trinity, :memory, budget_bytes: 8_192`. Tests: the snapshot's order and determinism; AC7 (a + session-scoped memory in A is absent from B's snapshot; promoted to the persona scope it is present, and the + promotion is an effect receipt). +4. `Trinity.Memory.Consolidator`: over budget after a write, the LLM (`generate_object/3`) is given the entries and + asked for a smaller set under the budget; applied at once when under budget (every removal and change + logged with the proposal id), else a pending `memory_proposals` row for review. Test AC3 with the fake + provider's scripted object: totals under budget after, every dropped key in the log, and the over-budget + answer queued rather than applied. +5. The `memory` tool (`Trinity.Tools.Memory`, risk `:write`, effect `:artifact`): `action` add/replace/remove/ + promote/list, `tier`, `key`, `body`, `scope` (default `persona`; `session` for this session only). Through the + membrane like any artifact effect; allowed by the persona rule without asking. Test AC2 (add, then the next + session's prompt carries it) and AC6 (the decision receipt names the basis `persona`: `Permissions.Policy` + gains an optional `decide_with_basis/4`, which `Layered` implements and the runner records). +6. `Prompt.build/4` takes the frozen snapshot from the Session's state (computed at start and on + `Session.refresh_memory/1`) and orders the system prompt stable → context → volatile, each tier cut at its + token budget with a query receipt naming the tier and the tokens dropped (the Session writes it, Sessions + gains the Receipts edge: deviation b). Tests: the order; a snapshot edited mid-session does not change the + prompt until refresh; a truncation writes its receipt; AC4 (two personas, two concurrent sessions, prompts + differ). +7. UI: `/personas` (list, picker on new session) and `/personas/:id` (SOUL editor, model, quick settings); + `/memory` (profile and always-on lists with inline edit and delete, the pending proposals with apply and + reject). LiveView tests; screenshots for AC5. +8. docs/05 synced (the three tables as built); docs/01's Sessions row gains Receipts. + +Manual verification queue (one item, for the owner at G4): +- **AC5**: edit the SOUL, add and delete memory entries, and see them persist. Screenshots under `proof/` + from the test registry server; the owner repeats on their own build if they wish. + +Deviations stated before any code: (a) the persona schema stays `Trinity.Sessions.Persona`; `Trinity.Personas` +is the context over it (moving the schema touches every slice since 010 for no gain); (b) the truncation +receipt is written by the Session, so Sessions depends on Receipts (docs/01's row is updated as built); (c) the +`memory` tool's default scope is the persona's, so AC2's three-argument add is visible to the next session, and +AC7 uses the explicit `session` scope and `promote`; (d) the volatile budget is 2,800 tokens, not 200 to 500, +for the reason measured above.

00b88bba8429f25105db70d8bd638a53a7c7d7ea Mon Sep 17 00:00:00 2001 From: Ayla Croft Date: Sun, 20 Sep 2026 20:48:45 -0400 Subject: [PATCH 3/8] feat(s030): the memory tool; the decision basis in the receipt Trinity.Tools.Memory (risk write, effect artifact): add, replace, remove, promote, list over the session's chain, the persona's scope by default and the session's on request; the persona from the context, never from Sessions. A policy may answer {decision, basis} and Layered names its layer; the runner carries it into the decision receipt, so the memory tool's writes read allowed by persona (AC6). Six tests; the 013 and 020 tests updated for the seeded soul and the new core tool.

the frozen snapshot in the Session Prompt.build_with_report/5 orders the system prompt stable (soul, tool guidance), context (skills placeholder), volatile (the memory snapshot, the time, the title), then 023's compaction section; each tier cut at its token budget on a line boundary and reported. The Session freezes the snapshot at start, recomputes it on refresh_memory/1, and writes a query receipt naming the tier and the tokens dropped for every cut (Sessions gains the Receipts edge). Tests: the order, the cut and its report, AC1's prompt half, the frozen snapshot through three turns and the receipt, AC4. The 012 purity test takes the time as an input.
