docs: prepare v1.3.0 release notes

P0 implementation with four waves:

Wave 1: Dedup with accounting
- Add dedupeLongTermEntriesWithAccounting()
- Classify exact duplicate, identity duplicate, topic duplicate

Wave 2: Normalization with accounting
- Add normalizeWorkspaceMemoryWithAccounting()
- Chain redaction → migration → enforceLongTermLimitsWithAccounting

Wave 3: Promotion accounting integration
- Update accountPendingPromotions() to use new accounting API
- Add supersededKeys to classification
- Distinguish promoted / absorbed / superseded / rejected

Wave 4: Integration tests
- End-to-end tests covering full pipeline

Bug fixes:
- Fix active vs superseded boundary (superseded entries no longer block promotion)
- Remove unused rejected_duplicate_lower_quality type
- Defer pending journal safety cap (TODO added)

Tests: 135 passing (up from 115)

-## [1.6.0] - 2026-05-08
-
-### Added
-
-- Numbered compaction memory references (`[M1]`, `[M2]`, ...) for existing rendered workspace memories.
-- Compaction memory commands: `REINFORCE [M#]` for retention reinforcement and `REPLACE [M#] [type] text` for protected replacement.
-- `CompactionMemoryRef` session-state snapshots with optional compaction IDs for overlap detection.
-- Evidence events for numbered memory command outcomes: `memory_reinforced`, `memory_replaced_numbered_ref`, and `memory_reverted_numbered_ref`.
-- Public `memory-diag commands` report for command counts, outcomes, rejection reasons, protected replacement blocks, malformed commands, and latest command events.
-- Public dry-run-first `memory-diag revert` command for manually reverting successful numbered replacements by replacement memory ID or evidence event ID.
-- Hard quality rejection reasons for unresolved questions, transient bug/debug state, and deployment snapshots.
-- Soft `terse_label` diagnostic for very short label-like candidates.
-- Regression tests for command parsing, REINFORCE, protected REPLACE, revert behavior, compaction ref validation, overlap protection, and fallback behavior when the model omits the compaction snapshot ID.
-
-### Changed
-
-- Compaction prompts now include numbered memory refs and concise memory-operation rules instead of asking the model to reuse existing wording exactly.
-- Compaction no longer duplicates hot session state inside the compaction prompt; hot state remains available in normal prompt context.
-- Duplicate maintenance now prefers explicit REINFORCE or protected REPLACE evidence over silent duplicate restatement.
-- Rendered decision memory cap increased from 10 to 12 while keeping the global rendered cap at 28.
-- Rejected memory command evidence now uses neutral `target` relations instead of lifecycle-mutating `reinforced` or `superseded` relation roles.
-- `memory-diag` public command metadata now includes `commands` and `revert` alongside `status`, `rejected`, `missing`, and `explain`.
-
-### Fixed
-
-- Overlapping same-session compactions can no longer silently apply numbered commands against the wrong snapshot when the snapshot ID is present.
-- Numbered command resolution now rejects stale refs whose memory ID, status, or exact key no longer match the current workspace memory entry.
-- Protected replacements are surfaced as first-class diagnostics instead of being buried in generic rejection counts.
-
-### Recovery note
-
-Successful numbered replacements supersede the original memory and add a replacement. To inspect or recover one, run `memory-diag commands --verbose`, then dry-run `memory-diag revert --memory <replacement-memory-id>` or `memory-diag revert --event <event-id>` before adding `--apply`.
-
-## [1.5.5] - 2026-05-05
-
-### Added
-
-- Section-aware greedy line accumulator for hot session state rendering that fits whole lines instead of truncating mid-line.
-- `accountHotSessionStateRender()` accounting function returning prompt text, omitted items, and char budget for v2 evidence extension.
-- Exported types for render accounting diagnostics: `HotStateSection`, `HotStateOmissionReason`, `HotStateOmittedItem`, `HotSessionStateRenderAccounting`.
-- 9 direct unit tests for hot session state rendering covering empty state, ranking, section caps, char budget, boundary conditions, header suppression, wrapper parity, and newline counting.
-- Two-layer omission model: section caps first (`section_cap`), then char budget (`char_budget`), with clear per-item omission reasons.
-
-### Changed
-
-- Hot session state rendering no longer uses blunt `.slice(0, maxRenderedChars)` prompt truncation.
-- Header-only sections are suppressed: a section is only rendered if at least one entry line fits the char budget.
-- `renderHotSessionState()` is now a delegation wrapper to `accountHotSessionStateRender().prompt`, preserving backward compatibility.
-- Fixed `docs/configuration.md` active-file ranking formula: was `count * action_weight * recency_decay` with weights 4/3/2/1, now correctly `ACTION_WEIGHT[action] + count * 3` with weights edit 50, write 45, grep 30, read 20, tie-break by `lastSeen` descending.
-- Clarified `README.md` system prompt injection order: workspace memory and hot state index positions depend on whether workspace memory state is available.
-
-### Fixed
-
-- Hot session state prompt could be truncated mid-line under the old `.slice()` budget enforcement.
-
-## [1.5.4] - 2026-05-02
-
-### Changed
-
-- Centralized the supported `memory-diag` command metadata for the official public commands: `status`, `rejected`, `missing`, and `explain`.
-- Removed pre-public legacy aliases so unsupported spellings now use the standard unknown-subcommand path instead of carrying v2.0 compatibility debt.
-- Kept `coverage` and `audit` as hidden maintainer diagnostics with neutral maintainer-only notices.
-- Removed public npm script exposure for the internal workspace cleanup tool while keeping the development tool in the repository.
-
-### Fixed
-
-- Moved missing-memory disappearance detail formatting into the official `missing` formatter before deleting legacy disappearance formatter code.
-
-## [1.5.3] - 2026-05-02
-
-### Added
-
-- Published the read-only `memory-diag` package binary for package-qualified `npx --package opencode-working-memory memory-diag` usage.
-- Added user-facing diagnostics commands for concise status, rejected memory review, missing memory review, and per-memory explanation.
-
-### Changed
-
-- Reworked the diagnostics CLI into focused command, model, formatter, and utility modules while preserving legacy aliases and maintainer diagnostics.
-- Updated README and configuration docs to document the supported `memory-diag` CLI workflow and package-qualified `npx` usage.
-- Raised the Node.js requirement to `>=22.6.0` for the TypeScript diagnostics CLI runtime.
-
-### Fixed
-
-- Avoided repeated workspace snapshot construction in status diagnostics.
-- Replaced per-memory evidence summary lookups with grouped evidence processing to avoid N+1 diagnostics work.
-- Added top-level CLI error handling for cleaner user-facing failures.
-- Removed a diagnostics model circular dependency by extracting evidence grouping helpers to a neutral module.
-
-## [1.5.1] - 2026-04-30
-
-### Added
-
-- Per-workspace evidence log for extraction, promotion, reinforcement, render, storage, and hook lifecycle events.
-- `memory-diag health --json` for machine-readable diagnostics.
-- `memory-diag explain` for per-memory render status, strength, reasons, and evidence event IDs.
-- `memory-diag trace --memory <id>` for memory lifecycle history.
-- UTC calendar-day reinforcement gate so repeated matches cannot inflate a memory multiple times in the same day.
-
-### Changed
-
-- Retention constants and calculations moved to `src/retention.ts`.
-- `safetyCritical` is now fully inert: no retention multiplier and no type-cap bypass, while remaining JSON-compatible.
-
-## [1.5.0] - 2026-04-29
-
-### Added
-
-- Strength-based workspace memory retention using exponential decay instead of additive priority scoring.
-- Per-type rendered caps for workspace memory candidates: feedback 10, decision 10, project 8, and reference 6.
-- Dormant-workspace effective age: after 14 days without activity, additional dormant time counts at 0.25x for retention decay.
-- Reinforcement tracking for repeated memories, with same-session and one-hour guards to prevent accidental reinforcement spam.
-- Memory health diagnostics for stored vs rendered counts, type caps, global cap overflow, dormancy, retention monitoring, and strength-ranked top/weakest entries.
-- CLI smoke tests and regression fixtures covering retention decay, stale-prune removal, type caps, reinforcement, invalid timestamps, and diagnostics.
-
-### Changed
-
-- Workspace memory rendering now ranks entries by retention strength, not the previous priority/penalty model.
-- Confidence is retained for compatibility but no longer affects retention scoring.
-- Deprecated `safetyCritical` is retained for JSON compatibility but no longer affects retention strength or type-cap behavior.
-- Old or stale-marked memories are no longer hard-pruned; they remain stored and only fall out of rendered context through strength and cap competition.
-- Existing duplicate promotion and dedupe paths now reinforce the surviving memory instead of only absorbing the duplicate.
-- Health output now separates stored active memories from rendered candidates to make cap behavior easier to understand.
-- Default prompt budgets are lower after calibration against observed rendered output: workspace memory is 3600 characters and hot session state is 700 characters.
-
-### Fixed
-
-- Invalid `updatedAt` or `retentionClock` values no longer produce `NaN` retention strength or unstable sorting.
-- Dormant age calculation only discounts the dormant overlap since an entry was created, so new memories do not inherit old workspace dormancy.
-- Type max totals above the global cap are handled correctly: the global rendered limit still wins.
-
-### Not Included Yet
-
-- Delete tombstones and explicit `supersedes` chain enforcement remain deferred follow-up work.
-- Hot/warm/cold tiered storage remains a future v1.6 direction.
-
-## [1.4.0] - 2026-04-28
-
-### Added
-
-- Local migration audit log for the `2026-04-28-quality-cleanup` migration:
-  `~/.local/share/opencode-working-memory/migration-logs/2026-04-28-quality-cleanup.jsonl`.
-- Local extraction rejection log for rejected compaction memory candidates:
-  `~/.local/share/opencode-working-memory/extraction-rejections.jsonl`.
-- Sanitized real-workspace regression fixtures for memory cleanup migration behavior.
-- Safe workspace residue cleanup tooling that dry-runs by default and quarantines definite temp/test workspace stores instead of deleting them.
-
-### Changed
-
-- Unified memory quality rules in a shared quality gate for compaction memory candidates and cleanup checks.
-- Rewritten compaction memory prompt to reduce over-production of low-quality memories.
-- Changed quality cleanup migration to be conservative: it supersedes only high-confidence garbage patterns, including progress snapshots, raw errors, commit/CI snapshots, temporary status notes, active file snapshots, code/API signatures, path-heavy entries, and empty entries.
-- Soft heuristic failures (`bad_feedback`, `bad_decision`) are intentionally excluded from automatic migration cleanup to protect durable declarative memories such as branding rules, API facts, release rules, user workflow preferences, and architecture decisions.
-- Isolated test runs under a temporary `XDG_DATA_HOME` so test workspaces no longer pollute real local workspace memory data.
-
-### Recovery note
-
-The cleanup migration changes matching entries to `status: "superseded"`; it does not delete the entry. If a useful memory is superseded, inspect the migration audit log and restore by changing that entry back to `status: "active"` in the workspace's `workspace-memory.json`. The migration runs once per workspace.
-
-## [1.3.3] - 2026-04-28
-
-### Fixed
-
-- Added atomic cross-process storage writes with stale-lock recovery and heartbeat refresh to prevent concurrent memory-file corruption.
-- Scoped pending-memory promotion by owner/session so global unowned cleanup no longer removes active owned entries.
-- Retained source-aware pending memories until they are actually promoted, absorbed, superseded, or rejected.
-- Persisted load-time security redaction and expanded Bearer-token redaction to reduce secret retention risk.
-- Hardened workspace normalization, cache bounds, rejected-entry retention, and session cleanup behavior.
-
-## [1.3.2] - 2026-04-27
-
-### Fixed
-
-- Compatibility CI now installs dependencies with `npm install` so it works in this no-lockfile repository.
-- Compatibility CI now runs on Node 24, matching the test command's `--experimental-strip-types` requirement.
-
-## [1.3.1] - 2026-04-27
-
-### Added
-
-- Pending journal retention: max 50 entries, 30-day TTL, automatic pruning on save.
-- Plugin capability test to catch missing OpenCode hooks before release.
-- CI workflow for weekly OpenCode plugin API compatibility testing.
-- Indirect prompt-injection filtering for workspace memory candidates.
-- Expanded credential redaction for common API key, token, secret, credential, auth, and private-key labels.
-
-### Fixed
-
-- Pending memory journal entries are now bounded and pruned instead of growing indefinitely.
-- Adversarial memory candidates that try to override system instructions are rejected before storage.
-- Broader credential-like labels are redacted from workspace memory text.
-
-### Changed
-
-- Memory dedupe is now repo-agnostic: project/reference entries use exact canonical text plus generic URL/path identity, while decision/feedback entries no longer use repository-specific topic heuristics.
-- OpenCode plugin compatibility is documented and declared as `>=1.2.0 <2.0.0`.
-- README limitations now concisely document compatibility, secret handling, semantic-memory scope, plugin ordering, and multi-process write boundaries.
-
-### Known Limitations
-
-- Compatibility is tested against OpenCode plugin API `>=1.2.0 <2.0.0`.
-- Credential redaction is best-effort; do not store secrets.
-- This is working memory, not semantic search.
-- Other prompt or compaction plugins may conflict depending on plugin order.
-- Multi-process writes to the same workspace are not fully serialized.

-
-Use the read-only diagnostics CLI when you want to understand what memory is doing for the current workspace.
-
-| Question | Command |

-| Is memory healthy? | `npx --package opencode-working-memory memory-diag` or `npx --package opencode-working-memory memory-diag status` |
-| Why was something rejected? | `npx --package opencode-working-memory memory-diag rejected` |
-| Where did my memory go? | `npx --package opencode-working-memory memory-diag missing` |
-| Why is this memory shown or hidden? | `npx --package opencode-working-memory memory-diag explain <memory-id>` |
-| How are numbered memory commands behaving? | `npx --package opencode-working-memory memory-diag commands` |
-| Revert a numbered replacement? | `npx --package opencode-working-memory memory-diag revert --memory <replacement-memory-id>` |
-
-Global options:
-
-- `--workspace <path>` — inspect another workspace; defaults to the current directory.
-- `--verbose` — show detailed diagnostics.
-- `--json` — print machine-readable output where supported.
-
-Examples:
-
-```bash
-npx --package opencode-working-memory memory-diag status
-npx --package opencode-working-memory memory-diag rejected --verbose
-npx --package opencode-working-memory memory-diag missing --workspace /path/to/project
-npx --package opencode-working-memory memory-diag status --json
-npx --package opencode-working-memory memory-diag commands --verbose
-npx --package opencode-working-memory memory-diag revert --memory <replacement-memory-id>
-```
-
-`memory-diag revert` is dry-run by default. Add `--apply` only after reviewing the planned original/replacement status changes.
-
-The npm package is opencode-working-memory; the installed bin is memory-diag, so package-qualified npx avoids resolving a different package named memory-diag.
-
-Maintainer-only diagnostics and cleanup commands are intentionally not documented here. Future work: move those internal commands to `docs/development.md`.

 ## Configuration
 
 OpenCode Working Memory works out of the box.

+- Improve memory recording quality so only durable, useful facts are kept.
+- Strengthen deduplication and supersession so stale memories do not pile up.
+- Add better forgetting behavior for obsolete decisions, preferences, and project facts.

 # Release Notes
 
-## 1.6.0 (2026-05-08)
-
-### Numbered Memory Refs
-
-This release turns compaction from a one-way memory extractor into a memory maintenance loop. The model now sees numbered references for existing workspace memories and can explicitly reinforce a still-useful memory or propose a protected replacement when compaction reveals that old memory is obsolete.
-
-The goal is not to make memory more aggressive. It is to make memory more accountable: old facts should be strengthened when they keep proving useful, replaced only when the target is safe, and diagnosable when the model tries something risky.
-
-> **Good memory is selective memory.**
-> v1.6 lets memory say “this still matters” without copying it again — and lets obsolete compaction memories fade behind a safer replacement trail.

-```
-
-### What Changed
-
-- **Numbered memory refs**: compaction prompts now render existing workspace memories as `[M1]`, `[M2]`, ... references so the model can target a known memory instead of restating it as a duplicate candidate.
-- **REINFORCE commands**: `REINFORCE [M#]` increments the target memory's reinforcement count and updates its retention clock without changing its text.
-- **Protected REPLACE commands**: `REPLACE [M#] [type] text` supersedes the old memory and appends a replacement only when the target is safe: active, compaction-sourced, and not already reinforced.
-- **Reinforce + append workflow**: when a memory is mostly right but needs more context, compaction can reinforce the old memory and emit a new candidate for the new durable fact instead of mutating history.
-- **Compaction prompt restructure**: verbose type definitions and the old “reuse existing wording exactly” instruction were replaced with shorter command rules, categorization guidance, and concrete memory-operation examples.
-- **Hot state removed from compaction context**: active files, current errors, and pending session state remain in normal prompt context but are no longer duplicated inside the compaction prompt, saving budget and reducing accidental promotion of transient state.
-- **New hard quality gates**: unresolved questions, transient bug/debug state, and deployment snapshots are rejected as durable memory candidates.
-- **Soft terse-label diagnostic**: very short label-like candidates are reported for tuning without being hard-rejected in v1.6.
-- **Decision cap raised**: rendered decision memories now have a per-type cap of 12 instead of 10, while the global rendered cap remains 28.
-- **Overlap guard for compaction refs**: memory ref snapshots are tagged with a compaction ID when available, so overlapping same-session compactions cannot silently apply commands against the wrong numbered snapshot.
-- **Safer evidence semantics**: rejected memory command events use a neutral `target` relation role instead of lifecycle roles such as `reinforced` or `superseded`.
-
-### Why This Helps
-
-- Useful memories can become stronger through real reuse instead of duplicate extraction.
-- Obsolete compaction-sourced memories can be replaced with an explicit evidence trail rather than left to drift.
-- Manual, explicit, and already-reinforced memories are protected from automatic replacement.
-- Compaction prompt budget is spent on durable memory maintenance, not on duplicated hot session state.
-- Command outcomes are visible enough to tune the feature after release instead of guessing from reinforcement counts alone.
-
-### Diagnostics
-
-Inspect command behavior with:
-
-```bash
-npx --package opencode-working-memory memory-diag commands
-npx --package opencode-working-memory memory-diag commands --verbose
-npx --package opencode-working-memory memory-diag commands --json
-```
-
-The command report includes:
-
-- compactions with command evidence
-- REINFORCE and REPLACE counts
-- reinforced, superseded, rejected, and blocked outcomes
-- invalid or malformed command counts
-- same-type vs cross-type replacements
-- protected REPLACE blocks, split by reinforced target and protected source
-- latest command events in verbose mode
-
-If a numbered replacement needs manual recovery, use the dry-run-first revert command:
-
-```bash
-npx --package opencode-working-memory memory-diag revert --memory <replacement-memory-id>
-npx --package opencode-working-memory memory-diag revert --memory <replacement-memory-id> --apply
-```
-
-You can also target a replacement evidence event directly:
-
-```bash
-npx --package opencode-working-memory memory-diag revert --event <event-id>
-```
-
-### Safety Model
-
-- REINFORCE never edits memory text.
-- REPLACE is rejected for manual or explicit memories.
-- REPLACE is rejected for already reinforced targets.
-- REPLACE is rejected if the numbered ref no longer matches the current memory ID, status, and exact key.
-- If a compaction snapshot ID is present and mismatched, all numbered commands from that summary are rejected with `missing_memory_ref_snapshot`.
-- If the model omits the snapshot ID, v1.6 falls back to exact memory ref validation for compatibility and command effectiveness.
-
-### Upgrade Notes
-
-- No configuration changes required.
-- Existing workspace memory files remain compatible.
-- Existing session state remains compatible; old sessions without compaction ref snapshots fall back safely.
-- Existing evidence logs remain compatible; new command events are appended only after v1.6 runs.
-- `memory-diag` now exposes two additional public commands: `commands` and `revert`.

-
-### Hot State Rendering Health
-
-This release replaces blunt prompt truncation with a section-aware greedy renderer that fits whole lines and suppresses empty sections, plus render accounting types for future diagnostics.
-
-> **Good rendering is selective too.** If a section doesn't fit, omit it — don't cut it in half.
-
-### What Changed
-
-- **Whole-line rendering**: the hot session state prompt no longer truncates mid-line with `.slice(0, maxRenderedChars)`. A greedy line accumulator fits complete lines and stops when the next line would exceed the 700-char budget.
-- **Header-only sections suppressed**: a section heading is only rendered if at least one entry fits alongside it. No more orphaned `active_files:` headers with no content underneath.
-- **Render accounting**: `accountHotSessionStateRender()` now returns `prompt`, `omitted[]`, and `maxRenderedChars` so future v2 diagnostics can surface which items fell out and why.
-- **Two-layer omission model**: section caps (`section_cap`) trim per-type overflow first, then the char budget (`char_budget`) trims anything that doesn't fit. Each omitted item carries its reason and section.
-- **Backward-compatible wrapper**: `renderHotSessionState()` delegates to the accounting function and returns just the prompt string, preserving existing plugin behavior.
-
-### Docs Fixes
-
-- **Active-file ranking formula corrected**: `docs/configuration.md` now matches the actual implementation — `ACTION_WEIGHT[action] + count * 3` with weights edit 50, write 45, grep 30, read 20, tie-break by `lastSeen` descending. The old docs claimed `count * action_weight * recency_decay` with weights 4/3/2/1.
-- **Injection order clarified**: README now explains that workspace memory and hot state system-prompt positions depend on whether workspace memory state is available.
-
-### Not Included Yet
-
-- Evidence events for omitted items are deferred to v2, pending a `memory-diag` consumer to avoid unused storage litter.
-
-### Upgrade Notes
-
-- No configuration changes required.
-- Existing workspace memory files remain compatible.
-- Hot session state rendering behavior is intentionally different (cleaner output, no mid-line cuts), but the same information is presented when it fits within the budget.

-
-This cleanup release keeps the newly published `memory-diag` CLI small before legacy spellings become compatibility debt.
-
-### What Changed
-
-- **Official commands only**: the public CLI surface is `status`, `rejected`, `missing`, and `explain`.
-- **Pre-public aliases removed**: old spellings such as `health`, `quality`, `rejections`, `disappearances`, and `trace` are no longer recognized.
-- **Maintainer diagnostics clarified**: hidden `coverage` and `audit` commands remain available as maintainer-only diagnostics and stay out of public usage output.
-- **Cleaner internals**: current command metadata now has one source of truth, and legacy command/formatter wrappers were removed.
-- **Internal cleanup script hidden**: the workspace cleanup helper is no longer exposed as an npm script; the underlying development tool remains in `scripts/dev/`.

-### Published Memory Diagnostics CLI
-
-This release makes the read-only workspace memory diagnostics CLI available as the package binary `memory-diag`, with user-facing commands for checking memory health and understanding why memories are rejected, missing, shown, or hidden.
-
-> Good memory is selective memory — and diagnostics should explain the selection.
-
-### What Changed
-
-- **Published CLI bin**: run diagnostics with `npx --package opencode-working-memory memory-diag` or `memory-diag status`.
-- **User-facing commands**: `status`, `rejected`, `missing`, and `explain <memory-id>` are documented as the supported public workflow.
-- **Legacy compatibility**: existing maintainer and legacy commands remain accepted with deprecation notices where applicable.
-- **Cleaner CLI architecture**: the former monolithic diagnostics script is now split into focused command, model, formatter, and utility modules.
-- **Faster diagnostics**: evidence grouping avoids repeated per-memory evidence queries in snapshot diagnostics.
-- **Cleaner failures**: top-level CLI error handling now reports usage and unexpected command errors without noisy stack traces.
-- **Docs alignment**: README and configuration docs now use package-qualified `npx` commands to avoid resolving an unrelated package named `memory-diag`.
-
-### Requirements
-
-- Node.js `>=22.6.0` is now required because the published diagnostics binary runs TypeScript through Node's `--experimental-strip-types` support.

-### Evidence Loop and Explainability
-
-This release adds an evidence-based audit trail for memory lifecycle events and user-facing diagnostics for understanding why memories are rendered, promoted, or rejected.
-
-> **Evidence before sublimation.** Every memory decision can be traced.
-
-### What Changed
-
-- **Evidence log**: extraction, promotion, reinforcement, render, and storage events are now recorded in a per-workspace `events.jsonl` with 90-day retention and 5000-event cap.
-- **User explainability**: `memory-diag explain` shows per-memory render status with strength, reasons, and evidence. `memory-diag trace --memory <id>` shows the full lifecycle history.
-- **Machine-readable diagnostics**: `memory-diag health --json` outputs structured `MemoryDiagJSON` for scripting.
-- **Calendar-day reinforcement gate**: reinforcement now requires distinct UTC calendar days, preventing repetitive-task gaming that could inflate a memory's strength within a single day.
-- **SafetyCritical deprecation complete**: the `safetyCritical` field no longer affects retention strength or type-cap bypass. All memories fade by the same rules.
-- **Retention module extraction**: retention constants and calculations moved to `src/retention.ts` for cleaner separation.
-
-### Privacy
-
-- Evidence text previews are credential-redacted. Memory content is stored as truncated hashes, never in full.
-- Diagnostics default to redacted output. `--raw` is available for maintainers.

-
-### Retention Decay Model
-
-This release changes workspace memory retention from hard stale pruning and additive priority scoring to a strength-based decay model.
-
-Think of it like a forgetting curve: memories fade over time, but important and reinforced memories decay slower. Weak entries fall out of rendered prompt context by cap competition, not hard deletion.
-
-> **Memory should fade, so the agent can keep learning.**
-> Important memories decay slower, but every memory must leave room for newer project reality and avoid long-term memory pollution.
-
-```text
-  strength
-    │
- ██ │╲____   reinforced: slower decline
-    │     ╲______
- ▒▒ │            ╲__ ordinary memory
-    │               ╲
-    ├ ─ ─ ─ ─ ─ ─ ─ ─╲─ dynamic cap competition zone
- ░░ │                 ╲  easier for new memories to replace
-    │                  ↑ still stored, not deleted
-    └──────────────────────────────→ time / sessions
-```
-
-### What Changed
-
-- **Strength-based retention**: workspace memory now uses exponential decay: initial strength × age decay.
-- **Better initial strength**: type, source, and user importance now determine how strong a memory starts.
-- **No confidence scoring**: confidence remains in stored data for compatibility, but it no longer affects retention ranking.
-- **Type caps**: rendered workspace memory now caps feedback, decisions, project facts, and references separately so one type cannot monopolize all 28 slots.
-- **Deprecation:** `safetyCritical` field no longer affects retention strength or type-cap bypass. All system memories now fade according to the same rules. Safety rules belong in user-controlled `agent.md` files, not in system memory.
-- **Dormant-aware age**: after 14 inactive days, additional dormant workspace time counts at 0.25x so paused projects do not forget too aggressively.
-- **Reinforcement**: repeated matching memories reinforce the survivor and slow future decay, with same-session and one-hour guards to avoid accidental spam.
-- **No hard stale pruning**: old or stale-marked memories are no longer automatically dropped by age; they lose rendered space only through cap competition.
-- **Calibrated prompt budgets**: observed rendered output was typically under ~2000 characters for workspace memory and ~500 characters for hot session state, so defaults were reduced to 3600 and 700 characters to keep overhead lower while retaining buffer.
-- **Clearer health output**: `memory-diag health` now reports stored vs rendered counts, type caps, global cap overflow, dormancy, retention monitoring, and strength-ranked top/weakest entries.
-
-### Why This Helps
-
-- User preferences and explicit memories are less likely to disappear just because inferred project facts are newer.
-- Feedback, decisions, project facts, and references share prompt space more fairly.
-- Returning to an old workspace is less punishing because dormant time decays more slowly.
-- Maintainers can see why memories are rendered or capped instead of guessing from a single active-memory count.
-- Stale entries can fade out of prompt context without destructive cleanup.
-
-### Diagnostics
-
-Maintainers can inspect retention behavior with:
-
-```bash
-bun scripts/memory-diag.ts health
-```
-
-The health output now includes sections like:
-
-```txt
-Stored active memories: 28
-Rendered candidates: 20
-
-By type:
-  feedback  stored=17  rendered=10  typeCap=10
-  decision  stored=11  rendered=10  typeCap=10
-
-Retention caps:
-  type-capped entries: 8
-  global-cap overflow: 0
-
-Dormancy:
-  dormant discount active: no
-
-Retention monitoring:
-  high_importance_ratio: 0.0% (alert > 30%)
-```

-### Not Included Yet

-### Memory Quality Cleanup
-
-This release improves automatic workspace memory quality without risking broad cleanup of useful existing memories.
-
-The quality gate is now shared across compaction extraction and migration checks, the compaction prompt is stricter about what should become durable memory, and the one-time migration is intentionally conservative.
-
-### What Changed
-
-- **Unified quality rules**: memory quality checks now live in one shared module and apply consistently across feedback, decisions, project facts, and references.
-- **Stricter compaction output**: the compaction prompt now tells the model to save fewer memories and prefer durable facts, user preferences, architecture decisions, and hard-to-rediscover references.
-- **Conservative migration cleanup**: the `2026-04-28-quality-cleanup` migration only supersedes high-confidence garbage patterns, not every rejected memory.
-- **Audit logs**: automatic migration cleanup writes local JSONL audit records so superseded entries can be inspected and restored.
-- **Extraction rejection logs**: newly rejected compaction candidates are logged locally to help calibrate future quality rules.
-- **Regression coverage**: migration behavior is tested against sanitized real-workspace patterns to prevent mass false positives from coming back.
-- **Workspace cleanup tooling**: a dev/admin cleanup command can dry-run or quarantine definite temp/test workspace residues without deleting unknown missing-root workspaces.
-- **Test storage isolation**: test runs now use a temporary `XDG_DATA_HOME`, preventing fixture workspaces from polluting real local memory data.
-
-### What Gets Cleaned Up
-
-The migration may supersede existing `source: "compaction"` memories only when they match hard garbage patterns:
-
-- Empty entries
-- Progress snapshots, such as "Wave 1 completed successfully"
-- Test or suite count snapshots, such as "180 tests passed"
-- Raw errors and stack traces
-- Commit or CI snapshots
-- Temporary status notes, such as "Currently running npm test"
-- Active file snapshots
-- Code or API signatures
-- Path-heavy entries that are just rediscoverable file lists
-
-### What Is Protected
-
-The migration does not supersede entries whose only issue is a soft heuristic failure, such as:
-
-- `bad_feedback`
-- `bad_decision`
-
-This protects useful declarative memories like:
-
-- Product branding rules
-- API facts
-- Release rules
-- Architecture decisions
-- User workflow preferences
-
-Explicit and manual memories are also protected.
-
-### Migration Behavior
-
-- Runs once per workspace.
-- Only affects active `source: "compaction"` entries.
-- Marks matching entries as `status: "superseded"` instead of deleting them.
-- Adds `quality_cleanup` and `quality:<reason>` tags to superseded entries.
-- Writes audit logs to:
-  `~/.local/share/opencode-working-memory/migration-logs/2026-04-28-quality-cleanup.jsonl`
-- Writes extraction rejection logs to:
-  `~/.local/share/opencode-working-memory/extraction-rejections.jsonl`
-
-### Recovery
-
-If a useful memory is superseded, inspect the migration audit log and restore the entry by changing its status back to `"active"` in the workspace's `workspace-memory.json`.
-
-### Workspace Residue Cleanup
-
-If old test/temp workspace stores already exist locally, inspect them first:
-
-```bash
-npm run cleanup:workspaces -- --dry-run
-```
-
-To move definite temp/test residues into a local quarantine folder instead of deleting them:
-
-```bash
-npm run cleanup:workspaces -- --quarantine
-```
-
-The cleanup command skips existing workspace roots and unknown missing-root workspaces by default.
-
-### Upgrade Notes

-
-This patch release keeps the v1.3 memory-consolidation model intact while tightening storage safety, compatibility checks, and repository-agnostic dedupe behavior.
-
-### What Changed
-
-- **Bounded pending journal**: pending memories are capped at 50 entries and pruned after 30 days.
-- **Security hardening**: workspace memory candidates now reject indirect prompt-injection attempts, and redaction covers broader token, secret, credential, auth, and private-key labels.
-- **Compatibility coverage**: plugin capability tests and weekly OpenCode plugin API compatibility CI help catch hook drift before release.
-- **Repo-agnostic dedupe**: long-term memory dedupe no longer depends on hardcoded project-specific topic rules; project/reference memories use generic URL/path identity plus exact canonical matching.
-- **Clearer limitations**: README and changelog now document compatibility, best-effort secret redaction, working-memory scope, plugin ordering, and multi-process write boundaries.

+### Consolidation and Deduplication
 
 Memories are deduplicated and consolidated with accounting:
 
 1. Normalize exact text: lowercase, strip punctuation, collapse whitespace.
 2. Group project/reference entries by identity where possible.
-3. Keep decision and feedback entries on exact canonical matching to avoid broad semantic merges.
-4. Keep the best surviving entry by source, confidence, specificity, and freshness tie-breakers.
+3. Group decisions and feedback by topic where possible.
+4. Keep the best surviving entry by source, confidence, type, and freshness rules.
 5. Emit accounting events so pending memories can be classified as promoted, absorbed, superseded, or rejected.
 
 This prevents absorbed or superseded pending memories from retrying forever while still preserving the active surviving memory.
 
-Retention then decides which active memories are rendered into prompt context. It does not hard-delete old memories by age.
-
-```typescript
-strength = initialStrength * 2 ** (-effectiveAgeDays / effectiveHalfLifeDays)
-```
-
-Initial strength is based on memory type, source, and optional user importance. Confidence remains stored for compatibility but is not part of retention scoring.
-
-Rendered candidates are selected in this order:
-
-1. Exclude `status: "superseded"` entries.
-2. Compute current retention strength.
-3. Sort by strength descending.
-4. Apply per-type caps.
-5. Keep the top 28 rendered entries under the workspace memory character budget.
-
-Default type caps:
-
-| Type | Rendered cap |
-|------|--------------|
-| `feedback` | 10 |
-| `decision` | 10 |
-| `project` | 8 |
-| `reference` | 6 |
-
-The type-cap total is 34, intentionally above the global 28-entry cap. These are maximums, not quotas.
-
-Dormant workspaces age more slowly: after 14 inactive days, additional dormant time counts at 0.25x for retention decay. Repeated duplicate memories reinforce the surviving entry and slow future decay, but same-session and under-one-hour repeats do not stack reinforcement.
-
-### Safety-Critical Deprecation

-The `safetyCritical` field on `LongTermMemoryEntry` is deprecated as of the retention v1.5.1 model update. It no longer affects retention strength or type-cap bypass. The field is preserved in the type definition for backward compatibility with existing workspace memory JSON files, but has no active behavior. Safety rules should be maintained in user-controlled files such as `agent.md` rather than in system memory.

Direct `readJSON()` is fallback-oriented and does not mutate data except when corrupt JSON is quarantined.

-Score formula: `ACTION_WEIGHT[action] + count * 3`

-When scores tie, the most recent `lastSeen` timestamp sorts first. There is no recency decay factor in the score itself.

-## Hot Session State Truncation
-
-Hot state rendering applies section caps before the character budget:
-
-| Section | Rendered cap |
-|---------|--------------|
-| `active_files` | 8 |
-| `open_errors` | 3 |
-| `recent_decisions` | 8 |
-| `pending_memories` | 6 |
-
-After section caps, the renderer applies the 700-character budget with whole-line inclusion only. The prefix line is counted against the budget, and a section heading is emitted only when at least one entry from that section fits; header-only sections are suppressed.

-`accountHotSessionStateRender()` returns prompt and omission accounting for future diagnostics. Evidence event integration for hot-state render omissions is planned for v2.

-### Inspect Retention Health
-
-Use the diagnostics CLI to check memory health for the current workspace:
-
-```bash
-npx --package opencode-working-memory memory-diag status
-# or from a source checkout:
-npm run diag -- status
-```
-
-For detailed diagnostics, use `--verbose`:
-
-```bash
-npx --package opencode-working-memory memory-diag status --verbose
-```
-
-The status output includes overall health (OK/WARNING/DEGRADED), key metrics, and suggested next steps when attention is needed.
