Version Entry Protocol#

A new version entry is added to §2 when:

• A new file in the module reaches canonical status
• An existing canonical file receives a normative content change (not just typo fixes or metadata-only updates)
• A version bump occurs in OPERATORS.md (new symbols frozen)
• The module dependency graph changes (new files added or removed)

Bump Type Rules#

Append-Only Rule#

This file is append-only. New version entries are inserted immediately below the ## §2 · Version History header — above all prior entries — so the most recent version is always first. Prior entries are never edited. If a prior entry contains an error, add a correction note in the next version entry's Key Decisions block. Do not edit the original.

§2 · Version History#

New version entries are inserted here — above all prior entries.

v1.0.0 · 2026-08-13#

Bump type: initial release Sessions: 12 sessions across one founding day (2026-08-13) Files in module: 26 total Canonical: 6 · Scaffold: 19 · Archived: 1

Summary#

The founding version of FFF_Gravity. The module was designed, scaffolded, and partially canonicalized in a single day across 12 working sessions. The triadic gravity model — G = F_freq · F_fluid · F_force — was articulated in genesis dialogue (f_Source.md), formalized as f_Capture.md, enriched with metadata, operator tables, and session context, then expanded into a full 26-file module architecture with 5-wave dependency ordering. The institutional defense record (GravityOfDismissal.md) and all four Wave 1 admin files were completed canonical in v1.0.0.

Session-by-Session Record#

SES-20260813-001 · Initial f_Capture.md scaffold#

Files created:

Sections created in f_Capture.md: §1 Module Identity · §2 Canonical Description · §3 Triadic Equation · §4 Operator Registry (§4.1 Primary · §4.2 Derived · §4.3 State Flags) · §5 Stability Conditions · §6 Failure Modes · §7 Engineering Primitives · §8 Canonical Examples · §9 Future Applications · §10 Cross-Module References · §11 Document Metadata

Operators established: 6 primary · 4 derived · 5 state flags · 6 primitives · 7 failure modes (FM-001–007) 4 canonical examples (EX-001–004)

Key decisions:

• f_Capture(E, A, Φ) → Ω established as the canonical triadic equation
• Four discrete outcome states: stable orbit · decay orbit · escape · collision
• Five conjunctive stability conditions established as Capture Gate
• Naming convention: f_ prefix for all function files; uppercase for admin files

SES-20260813-002 · Metadata blocks added to f_Capture.md#

Files modified:

Changes:

• YAML frontmatter block added (module identity, changelog, dependencies, tags)
• HTML comment metadata blocks added to all §1–§11 sections
• severity column added to §6 Failure Modes table
• direction column added to §10 Cross-Module References table
• status column added to §9 Future Applications table
• operator_count and versioning policy added to §4 Operator Registry
• pure/side_effecting classification and reads/writes guards added per primitive (§7)
• example_id, parameters, tags, key_insight added per example (§8)

Key decisions:

• All section IDs (§1–§11) frozen from this point
• Metadata comment format established: <!-- metadata: ... --> HTML comments
• YAML frontmatter is the document's machine-readable authority; HTML comments are section-level

SES-20260813-003 · Session context added to f_Capture.md#

Files modified:

Changes:

• session_context: block added to YAML frontmatter (active session card, session history array, session flags, session invariants)
• §0 Session Context added as live session register (active session table, session history table, section touch map, resolution protocol)
• session: annotation added to every section, subsection, example, and primitive
• §12 Session Log added as append-only audit trail (SES-001 and SES-002 back-filled)

Key decisions:

• §0 Session Context established as the live register for all files going forward
• §12 Session Log established as the append-only audit trail
• Section touch map tracks which session last modified each section
• Session resolution protocol defined as 10-step close checklist

SES-20260813-004 · Operator tables added to f_Capture.md#

Files modified:

Changes:

• §4.1 expanded: added Type, Class, Domain, Range, Default, Constraints, Source columns
• §4.2 expanded: added Full Formula, Depends On, Output Range, Sign Convention, Interpretation
• §4.3 expanded: added Entry Condition, Exit Conditions, Valid Next States, Terminal columns
• §4.4 added: Master Operator Specification Table (all 15 operators in one place)
• §4.5 added: Operator Interaction Matrix (10×10 R/W dependency grid)
• §4.6 added: State Transition Table (full FSM — 12 transitions)
• §4.7 added: Operator Evaluation Order (10-step sequence with guards)
• §4.8 added: Operator Composition Rules (8 composition formulas)
• §5 enriched: Governing Operator and Evaluation Step columns added
• §6 enriched: Operators Involved and State Transition columns added
• §7 enriched: §7.1 I/O Signature Table added before primitive code blocks
• f_Capture.md version bumped to v1.1.0

Operators frozen in this session: All 9 primary, 4 derived, 5 flags, 6 primitives confirmed frozen at v1.0.0 notation

Key decisions:

• Operator interaction matrix (§4.5) established as the authoritative cross-operator dependency reference
• State Transition Table (§4.6) established as the FSM specification
• Evaluation order (§4.7) is normative — out-of-order evaluation is undefined behavior

• 5-wave dependency unlock sequence established
• All files flat in docs/FFF_Gravity/ — no subdirectories
• Canonical tag format: [FFF:GRAVITY:FUNCTION] and [FFF:GRAVITY:CAPTURE:VARIANT]

• 7 attack vectors named: Authority Ambush · Empirical Retrofit · Access Withdrawal · Priority Erasure · Social Quarantine · Identity Disqualification · Silence Treatment
• Defense posture derived from repository architecture (versioned commits, public timestamps, open-source distribution as primary defenses against erasure)

SES-20260813-SITEMAP-001 · docs/SITEMAP.md#

Files created:

Contents: 11 sections covering full docs/ tree (35 directories + 33 root files). FFF_Gravity integrated as §3.1 (first canonical FFF layer entry), §9 (module spotlight), §10 (cross-module reference map including FFF_Gravity ↔ SoN structural analog).

Key decisions:

SES-20260813-CL-001 · CHANGELOG.md (this session)#

Files created:

v1.0.0 · Files Summary#

v1.0.0 · Operator Summary at Release#

v1.0.0 · Key Invariants Established#

The following invariants are normative from v1.0.0 and require a major version bump to change:

1. G = F_freq · F_fluid · F_force — triadic gravity equation; nodes inseparable
2. f_Capture(E, A, Φ) → Ω — canonical function signature; frozen
3. ρ(Φ) = 0 always triggers FM-002 — no exceptions
4. β < 1.0 always produces flyby — no exceptions
5. All five Stability Conditions are conjunctive — no partial capture
6. Terminal states are irreversible — no transitions out
7. f_Source.md is read-only — historical record; never to be edited
8. Operator evaluation order (10 steps) is normative — out-of-order is undefined behavior
9. OPERATORS.md is the symbol authority — overrides all function files on conflicts
10. Frozen symbols (v1.0.0 set) cannot be renamed without a major version bump

§3 · Session Registry#

Flat cross-reference of all sessions. One row per session. Append new rows at the bottom. Sessions are never removed from this table.

§4 · Document Metadata#

Append-only version history for FFF_Gravity. New version entries go at the top of §2. New session rows go at the bottom of §3. Never edit a prior entry — add corrections in the next version's Key Decisions block.
