v2.0.1

v2.0.1 — pheromone_tail: fix hook-path traces never reaching the field

v2.0.0

v2.0.0 — Identity removed from field physics (BREAKING)

v1.0.9

fix: make field socket Unix-only

v1.0.8 — Space derivation fix

Fix: space derivation now walks to project root instead of taking the last 2 path components.

Previously a single project was fragmented into multiple spaces whenever the user cd'd into subdirectories (e.g. ~/Desktop/Oasis_App, frontend/android, Oasis_App/backend all resolved to distinct spaces). This silently broke Level 1 stigmergic reinforcement — a textbook K-fragmentation confirmed in primordial-soup exp_task_diversity (K=5 → 99% drop in strong traces).

New service::derive_project_space(path) walks ancestors looking for:

1. .git (dir or file) — repo root
2. Common project manifests (Cargo.toml, package.json, pyproject.toml, go.mod, pom.xml, build.gradle[.kts])
3. Legacy fallback: last 2 path components

Migration: none. Old traces keep their old space labels and fade under the 168h decay; new traces write under the corrected identifier.

6 new unit tests. Full suite (380+ tests) passing.

v1.0.7 — Outcome-enriched co-edit observations

Co-edit observations now carry outcome quality (success rate %) alongside frequency.

• count_co_occurring_sessions returns CoEditStats with total + succeeded counts
• Prehook output shows coupled: eval.rs (3 sessions, 87%) when sample >= 3
• Foundation for stigmergic emergence: spatial coupling × outcome quality

v1.0.3

Hebbian direction in field observations

Primordial-soup experiment proved: valence-only = 0% agent improvement, valence + Hebbian direction = +27.2%.

FieldScan gains coupled_from field. Capabilities surfaced via Hebbian coupling now show their predecessor:

field: project tool:edit (78% success in this project, follows tool:search)

The field's relational dimension — directed edges discovered through co-excitation — now reaches agents for the first time.

Changes

• pheromone.rs: coupled_from: Option<String> on FieldScan, set in Phase 2 of scan_at_level and scan_with_fallback
• hooks.rs: render_field_observation renders directional info when coupled_from is set
• Backward compatible: existing serialization unaffected via serde(default)

v1.0.2 — Close field→agent feedback loop

What's new

The field→agent feedback loop is now closed for the first time. Agents receive live field observations during prehook execution.

Signal-to-noise fixes

• Concrete early-stop removed: scan_with_fallback no longer stops at Concrete level, ensuring Project/Typed/Universal results always reach the render pipeline
• Lifecycle capability filter: Internal urn:thronglets:* capabilities (lifecycle, signal, presence, continuity) are excluded from agent-visible field observations
• Scan limit increased: 3→12 raw scan results, truncated to 6 rendered observations — enough headroom after Concrete filtering

Infrastructure

• Profiler now tracks field_observations count separately from emitted hints
• MCP stdio timeout increased (15s→30s) for reliability

Field stats (at release)

• 8,134 field points across 4 abstraction levels
• 55,791 traces from 514 sessions
• 4+ agent types contributing (claude-code, codex, openclaw, psyche)
• Hebbian co-activation clusters forming (Edit×Read=10, Grep×Read=8)

Full Changelog: v1.0.1...v1.0.2

v1.0.1

Architecture Refactor + cargo fmt

• main.rs 4985 → 26 lines — all 44 command handlers extracted into src/cmd/ module tree (9 submodules grouped by resource pattern). CLI data definitions moved to src/cli.rs. Two-tier context pattern (BaseCtx / FullCtx) cleanly separates identity-free and identity-required commands. Zero behavior change.
• Field IPC — long-running processes (MCP, HTTP, run) now serve the live pheromone field over a Unix socket (field.sock). Prehook queries the hot field via socket (~1ms) instead of loading stale JSON from disk.
• cargo fmt — applied rustfmt across entire codebase.

Full changelog: CHANGELOG.md

v1.0.0

feat: v1.0.0 — abstraction levels: give the field a dimension

One field, one physics, four abstraction levels.

FieldKey grows from (capability, bucket) to (capability, bucket, level).
One trace excites Concrete → Project → Typed → Universal simultaneously.
Same decay, Hebbian coupling, carrying capacity, corroboration at every
level — the physics automatically produces correct behavior:

- Level 0-1 (Concrete/Project) stay local — specific experience has boundaries
- Level 2-3 (Typed/Universal) sync via P2P — abstract knowledge flows
- Space isolation = Level 1 (explained, not deleted)
- scan_with_fallback() walks levels with early stop on strong signal
- v0.9.2 P2P crack fixed by design: remote traces skip Level 1

New: target_kind.rs (TargetKind × language → Level 2 bucket)
New: thronglets/field/v1 gossipsub topic for field snapshot sync
New: trust-discounted remote snapshot merge (0.7x)

294 tests green. Zero per-level constants. Zero clippy warnings on lib.
