A projection that asks +for many memories' latest evidence does so in ONE indexed read per owner through +`events_contextual_memory` (an expression index over the memory id), and the live +guards (validity, memory suppression, source retirement, derivation ancestry and +conditions) are answered for the whole candidate set in batched, owner-scoped +reads rather than a query per row. The per-memory latest read is NOT windowed to a +record count: a live rule whose newest evidence sits behind a burst of newer rows +is still answered, so no hidden total-claim ceiling can drop it. Source suppression +still checks the owner journal to avoid old-source resurrection, and the ancestry +it walks is bounded by the candidates' derivation closure, not by a fixed count. +Dependency projections inspect 128 events and return at most eight links/notices. +Only successful full reads of files up to 64 KiB can establish an exact-path link. +At most eight source reads per pass can establish eight edges.

The boundary test is a bounded lexical subset, not a shell grammar: a span inside an unquoted substitution or grouping construct is refused rather than parsed, and unknown syntax keeps the full per-row actions. No production cap, preview window, slot count, priority or authority order changed." +--- + +This draft starts from #1751 and keeps one canonical event journal. Source, +applicability, authority and validity remain separate. Ordinary automatic scope +is project-local unless the person's words explicitly grant wider applicability. +Approved rules retain their source conditions before actions. Existing standing +orders remain the only ratified scheduling mechanism; memory does not authorize +unrelated edits. Sync records replay identity and owner-proven pending tombstones, +but opposite-order conflicts remain arrival-ordered rather than convergent. + +Also in this head: exact authority is judged against a claim's own supporting span, +not the whole utterance; the harness gained optional `--model`/`--one-model` and an +explicit `CODEAF_CALL_LOG_BODIES=1` opt-in, and a dedicated profile that pins every +text seat; and the immutability law on the canonical journal is unchanged, so raw +audit growth stays an explicit limit rather than something pruned. + +A probe watch is bounded by the identity of the evidence it was shown, not by +the sentinel's wording: an unchanged positive reading is told once and stays +quiet, and only a reading that moved is judged afresh. A watch that asks to be +told once carries that as a compiled field — shown on the card, kept in the +document — and retires after its one durable, delivered line; a watch without +it speaks each change, and a rhythm keeps speaking on its schedule. + +Standing deliveries are durable-first with this head. A delivery is appended to +its inbox under the pending identity and Sync'd before anything is drawn or +queued, then offered to an open window on top of the note. The inbox dedups on +the identity across retries and restarts. The live handoff is at least once: a +line offered live and then folded when the window is reopened can be read twice, +because whether a screen drew the row is not observable here, and loss is the +direction this refuses to fail toward. A write that could not be made durable, +or an item with no address at all, is reported so the caller keeps the intent +rather than reading success. A ratified FILE watch is armed at the yes, so a +change between the card and the first wake is a change; a bounded scan that could +not read everything it matches sets no baseline, leaves a visible flag, and the +first complete look clears it. A ratified item also keeps the model policy it +was given on: when the session ran under `--one-model`, the origin records the +promise and the model, the origin is written at the schema barrier so a build +without those fields skips it, and the reloaded background pass resolves the +sentinel and every child text seat from the item's pin with the role pins, +tiers, fallback chain and nearest-model guess withheld. One behaviour changed +for the keyless walk: an undecided look (for example, a machine with no API key) +is counted as checked and writes nothing, rather than being published as a +failed check; the item stays due and is retried next pass. + +A recorded failure can also carry the later observed success that answered it. +The alternative is an `AttemptSucceeded` row whose `AlternativeOf` names the +failed attempt's source key, so an explicit forget of either source retires the +pair through the existing suppression join and the read side never shows a +success on its own. A source snapshot is labelled as a snapshot, never as the +live machine's own state. The rendered prior-outcome block is bounded by whole +records inside the one shared memory ceiling, and it states a fact once where it is actually +shared: when every row carries the same raw source snapshot and the same seen day, or the +same whole-command action launcher, that circumstance is stated once above the rows and the +per-row repetition is dropped, so two complete failure/alternative pairs fit where +repetition previously pushed the second one out. Rows whose structured source, day or +launcher genuinely differ keep their own exact statement, a span that stops inside a word, +quoted argument or heredoc is never factored, an unquoted substitution or grouping construct +is refused rather than parsed, and a pair that still does not fit is omitted whole with no +orphan alternative. A larger mandatory approved-rule load trims by whole +record exactly as before; no cap, preview window, slot count or authority priority changed. + +The condition sentinel is grounded in the person's own sentence. A watch's judgment now +carries the look's own command, or belt tool and arguments, beside the evidence — read +from the approved item and never re-derived — so a status-only probe against a readiness +ask is unknown rather than a false yes; the model-authored hint is the proposer's guess, +not the person's criterion. The stand tool asks for a read-only look at what the endpoint +or command actually returns. The recorded failing shape was measured at the production +seam on the review's pinned model, and that live matrix is an opt-in e2e regression that +skips with no key and is never acceptance. + +The built-in manual now names these limits in the words people use: an +app-closed watch has no separate helper to install; a `once` watch waits as an +inbox note rather than a notification or toast — in the conversation that made +it, or under the project when it came from home's `ask here` — and is delivered +only once, so reopening does not repeat it; a judged look runs on a model, so the +provider +serving THAT judge model must hold the credential — reconnecting an unrelated +provider leaves the watch where it was — and a look the judge model's provider +cannot pay for queues no note, leaves the item active and due, and is retried +once that provider is connected; and a check missed while the machine was off or +asleep is a best-effort request rather than a guarantee, and only while +background checks are on. It also draws the distinctions the old +pages blurred: an observed prior attempt is an advisory read before a relevant +turn, not the error-fix suggestion looked up only after a command fails; the one +shared store is not one shared scope, so "a memory kept in one project is there +in the next" is gone in favour of the closed shelves — you, this workspace, +this machine — with no memory owned by a whole team; and while a manager, a new +member and a task in that workspace read the workspace's approved rules and +confirmed decisions locally and deterministically before their first request (a +task read-only and bounded, with no provider asked), that binding read is a +separate path from the router's advisory relevant-memory shortlist, and a search +of an old conversation is reading only — it does not reactivate a forgotten +decision. The failed-method page now answers whether remembering a failed method or +tool stops codeaf trying it again: that observed-outcome advisory is read locally +from the saved memories before the first request and is not gated by the router's +ranking or small relevance model, it bans no tool, and with changed inputs or +circumstances the agent may retry or adapt rather than being forbidden — it never +promises a retry either. The changed-input page states the same line one more +way: with the data file changed, a past observed result is kept as historical +advisory and is not automatically erased or retired, no rerun is forced, and a +fresh inspection of the changed file is needed before the prior result may be +reported as current. The scope list now names which mouth is which: an +omitted scope on the `remember` tool means this project, and only `/remember` +is the personal save kept as you — the engine's default, not a claim that +the personal save is the default. Retrieval probes for these questions are in +`internal/manual/chat_test.go`. + +Final-head terminal acceptance is required before this entry is treated as +landed, and focused tests alone do not establish real work improved: the acceptance runs +against the frozen final head on the pinned model, and any key-skipped e2e run is a skip +rather than a pass.

A bounded consumer reread checks whether its recorded +assumption is unchanged after a producer content change, and offers a hypothesis to +inspect rather than asserting breakage or authorizing consumer edits. A PAIRED +re-read of a changed producer and an unchanged consumer does not reset the recorded +baseline: a successful full read alone is not demonstrated compatibility, so the +consumer's earlier producer circumstances stand until the consumer's own assumption +changes. Impact scanning is driven by observed state, not by a keyword list in the +turn, so ordinary wording is not missed. Dynamic dependencies, partial reads and +arbitrary shell programs remain unresolved. + +Dismissal is precise. With several offers held, naming one dismisses only it, an +explicit plural dismisses the batch, and a bare dismiss that names nothing dismisses +nothing; "do not dismiss" and "don't dismiss" are negations and keep the offer. +Dismissal identity is content-based, persists as a canonical suppression across a +restart, and a later content change may be offered again. The held offer set is +bounded and EVICTABLE, so more than eight historical notices cannot permanently +block new material. A notice is model-facing context, not proof the person saw it. + +Binding retrieval spends its window on authority: approved rules and confirmed +decisions are read through their own bounded projection, so a burst of newer +incidental observations cannot starve a live rare constraint, while latest +correction, expiry, conditions and suppression still win. Authority and scope +are judged against the claim's own supporting span, not the whole utterance, so a +true quote of ordinary talk cannot manufacture a rule. The containing clause must +also be an assertion: a rule inside a question ("Should we never use pandas?") or a +rejected third-party quotation ("The reviewer said never use floats, but I reject +that") is demoted to a proposal, while a polite real directive and an ordinary +literal constraint still bind automatically. Scope is gated the same way and +conservatively: a project span stays in its project even beside a global sentence, +only an explicit machine-wide span may take machine scope (which then applies across +projects on the same authorized machine and carries no project condition), and no +tool observation is inferred machine-wide. Widening to the person at large runs from +the person's own unambiguous words: a cross-project grant ("across all projects") +widens, while a bare "everywhere" stays in the project because it is ambiguous +between the person and a span the clause never named, and a clause with a project +qualifier ("in this app", "our repo", "this monorepo"), an exception ("unless", +"except") or a restriction ("only", "restricted to") stays local. Receipts from conversation +history, this session's memory reader and task summaries are derived, not +independent observations: citing one back cannot corroborate a claim, which also +keeps suppressed history from re-entering as fresh proof. Genuine raw tool receipts +are unchanged. A standing run lent the canonical brain for binding is read-only: it +sees the owner's approved rules before its first action and extracts, observes, +imports and remembers nothing back. With memory ON this binding is a promise, not +a best effort: if the owner cannot be proven, the brain cannot open, or the +binding read fails, the run refuses before any provider or tool call and the item +is left a visible needs-person task that is not replayed. Memory off remains +intentionally absent. An already-supplied brain is still bound, never bypassed. + +Forgetting suppresses all historical sources of a claim and derived use; the raw +original conversation history remains on disk and can still be searched explicitly, +and that retention is not an automatic reuse path because a history receipt cannot +become independent observation. The notice/receipt attention state is bounded and +evictable; the immutable events_no_delete journal still grows, and that raw audit +growth is an explicit, honest limit rather than something pruned away. Completed/abandoned user-declared work can expire from +recall. Existing idle maintenance and standing orders remain the only maintenance and +scheduling machinery. Deferred intention retention alone does not guarantee a standing +order was proposed or ratified. + +A recorded failure can carry one later observed successful alternative from the same +turn and goal: the same tool class, an action sharing a meaningful token, taken at the +true tool boundary, never a lookup or a model summary. It is rendered beside its failure +with its own receipt and source snapshot, as observed history rather than a cause or a +ban; a matching snapshot is not the environment, so changed or unknown circumstances +still invite fresh verification. No other success is retained, and forgetting either +source retires the pair. + +Full product expectations require final-head terminal evidence.

Write path — one door + +1. Normalize text; classify kind and tags (extraction model, already running). +2. Resolve owner. `/remember` and the tool set it explicitly. Extracted owner + is a proposal: promoting anything to `team:` requires user confirmation. +3. Same-owner duplicate and conflict search (FTS5 + edges; vectors when the + plugin exists). Never cross-owner — two projects may hold genuinely + different truths about the same words. +4. Decide: add | new-version (supersede) | skip-duplicate. +5. Emit edges proposed by the extraction model (`relates_to`, `contradicts`, + `supersedes`). +6. Journal the outcome. + +Consequences by construction — ALL FOUR SHIPPED: + +- The audit's split-door dedup bug disappears: there is one door. +- Cross-project updates become impossible: conflict search never leaves the + writer's owner. +- Import correctness: the legacy importer checks `scanner.Err` and every row + result; it renames the source file only when every row landed, and the + retry is idempotent because kept lines skip at the same door. +- Extraction failures journal `memory_write_failed` with the error instead of + vanishing, are said once per five-minute window as a dim line, and fall + back to `v3/memory-failures.log` when the store itself is what failed. + +**Corrected — the decider is never a permission.** The early draft let a +failed model settle refuse an explicit save. Shipped: the decider's failure is +journaled and the words still land through the store's own dedup door. Model +enrichment improves writes; it is never the difference between a save +happening and not happening. + +**Corrected — the dedup door is deliberately small.** Exact text (case and +whitespace folded) or exact title, within the same owner, is a duplicate; +everything subtler is the decider's job. A similarity threshold would be a +guess wearing a rule's clothes, and two lines that are not the same words are +not the same memory. + +## 4. Read path — the funnel + +Deterministic, no LLM required, every tier optional except the first two. +Each tier emits a ranked ID list; reciprocal-rank fusion (k=60) merges +however many contributed. A missing tier is a no-op, not an error. + +**Corrected — nothing truncates the corpus before lexical.** The early draft +capped the structural tier at 200 candidates and implied the funnel ran +through that cap. Shipped: the lexical tier runs over the WHOLE owner's +active set (it is an indexed read — truncating it before the query would make +memory two hundred and one unreachable forever, the defect the store already +removed once), and the k of the final budget is the only cut that happens +after ranking. + +``` +1. Structural WHERE owner IN visible(ctx) AND status='active' + AND (review_after IS NULL OR review_after > now) + → ranked, no cap (the whole owner's active set) +2. Lexical FTS5 BM25 against the turn text → top 50 +3. Edges 1-hop relates_to/contradicts/co_used neighbors of the + current top 20 → joined at their edge weight +4. Vectors brute-force cosine over memory_vectors, if the table + exists → top 50 (optional plugin) +5. JIT rerank one aux-model call ranking the fused top 30, ONLY when + the fused pool above the cutoff exceeds 2×k and an aux + model is configured (optional booster) +6. Budget top k (≈8) → inject, each with a why-line naming the + tiers that nominated it ("same repo", "used 12×", + "you corrected this") +7. Journal fold suggestions into memory_stats; record used/contradicted + as raw events +``` + +Why brute force is fine for tier 4: 10k memories × 1536 dims ≈ 15M +multiply-adds — milliseconds. A vector index is a 100k-row problem; revisit +only there. + +Cold start (no edges, no usage, no vectors) rides tiers 1–2, which is already +stricter than today's unfiltered LIKE search. + +### Semantics without embeddings + +Embeddings are one of four sources of relatedness; the other three need no +provider capability at all: + +| Source | Computed | Cost at read | +|---|---|---| +| Structural + lexical | always, in SQL | none | +| Write-time edges (`relates_to`/`contradicts`) | extraction model, once per write | one SQL join | +| Behavioral edges (`co_used`) | tidy, mining the journal | one SQL join | +| Vectors | optional provider plugin | milliseconds | + +No install downloads anything. The fallback for a provider without +embeddings is not a degraded system — it is the designed baseline. + +## 5. Scale plan + +Assume heavy use: 5–20 durable memories/day → 2–7k/year. **These are +estimates, not benchmarks** — nothing in this repository has measured them +yet, and a number quoted from this section is a design assumption, never a +measurement. + +- **Archive never scanned**: partial index keeps active-set queries O(active), + not O(history). +- **The journal is the flood, not the memories.** `suggested` fires every + turn, so it is aggregated into `memory_stats` counters at write time. Raw + events are kept only for `used`, `contradicted`, `written`, `superseded`, + `write_failed`, `tidy` — low volume, high value. +- **Keyset pagination everywhere**: `/memories` and the activity feed page by + `(created_at, id)` cursors, 50 per page. No OFFSET. `ChangedSince` already + sequences the home screen and keeps its contract. +- **Budgets are hard caps**: k≈8 injected, tidy archives the long-unused. + Nothing truncates the candidate corpus before ranking: the structural tier + ranks the whole owner's active set and only the final k is cut. +- **Vectors isolated**: 6 KB/row at 1536 dims lives only in `memory_vectors`; + non-embedding installs never pay it. + +## 6. Relay readiness (PR #1738) + +Pay the schema cost now; pay the transport cost later. Four decisions already +in the schema do the work: + +1. **Immutable rows + supersede chains.** Replication is set-union of + immutable rows plus a fold of edges — convergent under any delivery order + or duplication. + + **Corrected.** Text conflicts are not made impossible by immutability + ALONE, because corrections in place exist: an explicit edit (the memory + place's `e fix the wording`) rewrites a row's text under its own id, and a + decider's "refine" does the same. Those are the mutable half, and the fold + gives them deterministic — not conflict-free — semantics: first applied + wins, the skipped half is counted, nothing resurrects a tombstone + ([Store.ApplyMemoryEvents]'s rules). The seam's contract is "deterministic + under any delivery order", which is the honest claim; "no conflicts" was + the early draft overpromising. +2. **Store-minted ULIDs.** Unique across devices without coordination. +3. **The journal is the replication log.** `(origin, origin_seq)` cursors are + exactly "what have you seen"; sync is exchanging `EventsSince` batches and + applying them idempotently. +4. **Owner namespaces are the sync policy.** One function: + +```go +func SyncPolicy(o Owner) Policy +// user: replicate to the person's paired devices +// project:: replicate with the project (follows the folder) +// team:: replicate to team members +// machine:: never leaves the device +``` + +What Phase 4 adds when #1738 lands: an adapter moving `EventsSince` / +`ApplyRemote` batches over its sealed object transport, reusing its device +identity and pairing. Memory never learns what pairing is; the relay never +learns what a memory is. Ordering: Lamport stamps for merge order, physical +time for display; status folds last-writer-wins per memory id; supersede +edges reference ids causally, so skewed clocks cannot corrupt a chain. + +Explicitly not built now: transport, pairing integration, encryption (the +relay's sealing carries events as opaque blobs later). + +## 7. Migration from the current schema + +Existing rows carry only `scope` (`user`/`project`/`env`) with no project +identity. **Shipped, and corrected where the early draft guessed:** + +- `scope=user` → `owner=user` — unchanged, provable from the row. +- `scope=env` → `owner=machine` — the store-level machine, because the device + identity is PR #1738's and it has not merged; a later relay migration can + resolve `machine` against the pairing without touching rows. +- `scope=project` → **`owner=project:legacy`, tag `legacy-project`.** The + early draft moved these to `owner=user`; that is the one move a migration + must never make — attributing an unknown project's memory to the person at + large WIDENS its visibility to every project. Quarantine never injects. +- Recovery: a door-side pass walks the state root's session folders, whose + `meta.json` records each session's workspace as a fact; a quarantined row + whose source session provably ran in a workspace is re-homed to that + project's owner ([Store.RehomeMemories], journaled). Rows nothing proves + stay quarantined, visible to the person and to nobody's model. +- Statuses map through (`active`/`superseded`/`forgotten` preserved). +- The migration is idempotent: a reopened store re-derives nothing. +- Every migrated row's history is already in the journal; no synthetic + `written` events are minted, because the journal being truth means the + migration may not add history that did not happen. + +## 8. Phases — shipped, and deferred on purpose + +### Shipped in this PR (substrate + trust) + +- **Owner column + migration** with quarantine, not re-attribution; the + door-side re-home pass recovers what the state root can prove. +- **Owner-keyed reads.** MemoryCandidates, SearchMemories, GetMemories and + MemoryPage take the session's visible owners and REFUSE an empty list; the + janitor's ListMemories keeps its unscoped read by contract. +- **One write door** across /remember, the remember tool, the routed + command, extraction and import, with same-owner dedup and both outcomes + journaled. +- **Visible failure:** journal events, a rate-limited dim line, a fallback + file when the store itself fails. +- **Lossless, idempotent import** with the scanner's error read. +- **Memory/search decoupling:** the conversation index is its own handle; the + memory row no longer takes the search verb down. +- **FTS5 proved at open**, with graceful degradation, no install step. +- **Keyset pagination** (`MemoryPage`), provenance and trust inspection as + they already existed (the memory card's provenance read). +- **The sync seam** (export/apply with owner policy, idempotency, tombstone + precedence) — proven by tests, wired to no transport. +- **Optional enrichment:** explicit saves never require the decider; + embeddings stay absent-by-default. + +### Deferred, and said so plainly + +- **Embedding vectors / memory_vectors** — Phase 3; interface is + provider-agnostic; no install downloads anything, nothing fails when the + provider has no embeddings endpoint, and the index is rebuildable and + model-separated when it arrives. +- **Edges, co-use mining, JIT rerank, review_after sweeps** — Phase 2.

Memory adds no second scheduler. + + +## Can I inspect the source behind a saved claim? + +The assistant can use `memory_evidence` for one saved memory id when its supporting +source matters to the work. It returns the source words or actual receipt, conditions, +rationale and circumstances for reconsidering the decision.

The +prior failure is shown **before** a matching action rather than only after a +failure. When a `bash` call fails, or is blocked before it runs, one row is +written the moment the call ends — no model is asked anything, so a single +extraction that found nothing, or a turn that rolled over, cannot lose it.

A +note goes through the router's ranking and its small relevance model, and only the +two or three lines that survive are shown. This observed-outcome advisory is read +**locally**, from your saved memories, before the first request goes out, chosen by its +own relevance to your turn and bounded to the rows that are relevant — **it does not +depend on the router's ranking or its small relevance model** and does not wait for +one. + +On a later turn, before the first request of the answer goes out, a prior failed +or blocked attempt that is **relevant to what you are asking** is put in front of +the model as an advisory line: + +``` +- Prior observed attempt [different source snapshot, seen 2026-10-03]: `bash: make build` failed; receipt "make: *** No rule to make target 'build'". +``` + +It is history, not a prohibition and not a cause: what failed once may work now, +and the line says so. **It never bans the tool, and nothing reads a memory to block +a call.** When the inputs, the tree or the circumstances have changed the agent is +free to try it again, or to take another route — the line may shape the choice but +does not settle it. It never promises a retry either: it is advice in front of a +decision, not the decision. A source snapshot, the day it was seen, or a launcher every +row genuinely shared is stated **once** above the rows instead of on every row, so +the bounded space is spent on observed work rather than on repetition; a row whose +own source or day differs keeps its own bracket. A failure of a task you are not working on stays quiet. A +successful call is not remembered on its own, so this is not a list of everything +that has ever worked — but where a later success was observed on the same work, +the block names it beside the failure as an `Observed successful alternative`. + +The label in the brackets is honest about circumstances: + +- **same source snapshot** — the failure was earned under exactly the commit and + the uncommitted changes the tree has now; +- **different source snapshot** — the tree has moved since; the failure may no + longer apply, so it invites a fresh check; +- **circumstances unknown** — the source could not be identified, and it is never + presented as current. + +A blocked call — a refused door, a hand taken off the belt — is recorded as +**blocked**, never as a failure, because a refusal is not proof that the approach +cannot work. An overall success on one command never proves a sub-check passed; +the row is only ever one observed result. + +The receipt is untrusted text and is **quoted** rather than obeyed, and any +secret-shaped span in it is redacted before it is stored. `/forget` retires the +claims a failure was provenance of, and the failures learned from the same +receipt with them — an unrelated failure in the same project is untouched, and a +genuinely new observation is kept. Turning memory off turns this off with it. + +## What happens to old command results when input files change? + +If a command failed last week and the data file has changed since, codeaf keeps +that old result as history but does not treat it as current proof. The recorded +failure stays in memory as a historical advisory: it says what was observed +once, under the source snapshot it ran against, so it can shape the next +decision. A changed input does not automatically erase or retire that history, +and it does not force a rerun. A changed file is a reason to look again, not proof +either way. + +What it must not do is call the old result still true.

Otherwise source=assistant and authority=proposal. authority=approved_rule requires an explicit user instruction; confirmed_decision requires an explicit user choice; other user statements are observations. Preserve rationale, rejected alternatives, and reconsideration circumstances in their separate fields. A failed attempt is an observation under its recorded conditions, not a demonstrated cause. Keep deferred intentions conditional; noticing an opportunity never authorizes unrelated edits. + +Retain unfinished project goals and decisions across conversations; when work finishes or is abandoned, describe that state rather than leaving an unfinished commitment. Set work_status=completed or abandoned only when the user explicitly closes the work; an assistant claim that tests pass is not user completion. Never turn a guessed test result into a confirmed outcome. + Add state ONLY when the exchange MOVED THE WORK — the goal changed, something finished, something started, the next step changed, a question opened, or a file or link became the thing being worked on. An exchange that only answered a question moved nothing and has no state. When a REMEMBERED section is given, also answer which of those memory ids actually bore on the answer — used. A line bore on the answer if the assistant would have answered differently without it. Copy the ids exactly. Most lines bore on nothing, and an empty list is the normal answer. Omit used when there is no REMEMBERED section. Answer with ONE JSON object and nothing else.
