governance: define the GLYPH Centenary 247 standard

[yasha1971-coder]

What changed

Adds four new files only:

• docs/governance/GLYPH_PRESERVATION_LAW_V1.md
• docs/governance/GLYPH_MOVEMENT_LEDGER.md
• docs/governance/GLYPH_CENTENARY_247_V1.md
• tools/check_centenary_247_v1.py

No existing file, tag, release, or branch content is deleted or modified.

Why

This establishes an additive, domain-neutral quality framework for GLYPH with exactly 247 atomic engineering facets. The catalog draws measurable practices from exact-search, storage-engine, formal-verification, reproducible-build, secure-supply-chain, fuzzing, API, and operational exemplars.

It also records the Owner directive effective 2026-08-14:

• only the Owner may authorize deletion or destructive replacement of durable project records;
• important moves require a dated ledger entry;
• better variants are additive and may supersede older variants without erasing them.

Evidence discipline

The document deliberately does not certify GLYPH merely by existing. It states:

247 DEFINED; 0 CLAIMED CLOSED BY THIS DOCUMENT.

Stars, forks, discussions, adoption, tests, formal proof, and independent replay are separate evidence classes. Final closure requires commit-bound evidence and independent replay.

Validation

facet_count = 247
facet_ids = F001..F247
section_count = 13
preservation_law = PRESENT
movement_ledger = PRESENT
GLYPH CENTENARY 247 STRUCTURE OK

Remote file contents were fetched from centenary-247-v1 and matched the locally validated source byte-for-byte.

Review focus

• Is every facet atomic and non-duplicative?
• Are any closure artifacts weaker than the stated claim?
• Does the preservation law match the Owner directive without blocking ephemeral build cleanup?
• Which existing immutable GLYPH artifacts can be mapped to facets without retroactive overclaiming?

Automated and independent review state

• Existing repository CI: run 31784103236 — success.
• The new 247 structural checker was run directly and passed; it is not yet wired into the repository's required CI graph.
• Independent review request: Independent review request: GLYPH Centenary 247 standard #8
• Independent scoped approvals at creation: 0.
• Issue comments at creation: 0.

These zeroes are recorded intentionally: the proposal creates a reviewable standard but does not manufacture external validation.

Additive identity/dependency refinement — 2026-08-14

The review target has advanced additively from the creation head 0122c2a... to:

87e2157e1b1f2361279c99016b3412a0ead7fd81

No earlier revision was rewritten or removed. PR boundary is now 11 commits, 6 changed files, 1,239 additions, and 0 deletions.

The preserved entity is now explicitly identified at two levels:

1. stable logical object ID, preserved across a pure move;
2. immutable revision ID sha256:<digest>, bound to repository, commit, Git blob, path, byte length, version, date, and authority.

Relationships are first-class identified edges: DEPENDS_ON, IMPLEMENTS, VERIFIES, EVIDENCES, PRODUCES, REFINES, SUPERSEDES, MOVED_FROM, COMPATIBLE_WITH, and INVALIDATES.

Before movement, supersession, destructive replacement, or proposed deletion, the transitive incoming dependency closure must be computed. Missing registry coverage is UNKNOWN, never “no dependencies”; unresolved dependents fail closed.

New review files:

• docs/governance/GLYPH_OBJECT_IDENTITY_AND_DEPENDENCY_V1.md
• docs/governance/GLYPH_OBJECT_GRAPH_V1.json

Current graph identity:

logical object:
glyph-object:governance:object-graph:v1

publication commit:
87e2157e1b1f2361279c99016b3412a0ead7fd81

content SHA-256:
294665bc5390ec380458d805a12f7e286fc734d78ca82cee7708371af04043b0

Git blob:
fa7a2077ec4ae5470999000c064741ce3e292581

Structural validation:

facet_count = 247
facet_ids = F001..F247
section_count = 13
registered_object_count = 6
registered_relation_count = 8
dependency_unknown_policy = FAIL_CLOSED
GLYPH CENTENARY 247 STRUCTURE OK

Independent review should use the new head. The creation head remains preserved as historical review context.

Validation update for review head 87e2157e1b1f2361279c99016b3412a0ead7fd81:

• GitHub Actions run: https://github.com/yasha1971-coder/glyph-engine/actions/runs/31787043495
• conclusion: success
• local fail-closed graph gate: PASS
• registered objects/relations: 6/8
• dependency unknown policy: FAIL_CLOSED

The repository CI success is recorded separately from independent technical approval; independent approval count remains zero until a reviewer supplies the scoped record requested above.

Preservation-register audit update — 2026-08-14

Current proposal boundary:

• head: e2f37209301ef09bfd097c90352bf71f436ad338
• commits ahead of main: 13
• changed files: 7
• diff: +1563 / -0
• base main remains unchanged at 9f79fd5cf8f969ed46c2c1ad7945f6b5a2944edb

Additive changes:

1. 7445592dac07a25bab06c45ea3db87e3ffd3e7bb adds docs/governance/GLYPH_PRESERVATION_REGISTER_V1.md.
2. e2f37209301ef09bfd097c90352bf71f436ad338 binds that register into the existing GLYPH_OBJECT_GRAPH_V1.json; no new graph version or parallel core was created.

The register records the 2026-08-14 preservation boundary for 12 branches, 12 tags, 2 releases, 643 tracked blobs, durable repository families, the proof/evidence promotion queue, source/citation retention, corpus and benchmark provenance, and fail-closed deletion handling. Recording an item preserves discoverability; it does not certify correctness, production readiness, or integration into main.

Validation:

facet_count = 247
facet_ids = F001..F247
section_count = 13
preservation_law = PRESENT
movement_ledger = PRESENT
registered_object_count = 7
registered_relation_count = 10
dependency_unknown_policy = FAIL_CLOSED
GLYPH CENTENARY 247 STRUCTURE OK

GitHub CI succeeded for both the push and pull-request events at the current head. The Centenary checker was also executed separately against byte-exact files fetched from the remote branch. Independent scoped approvals remain 0; this update does not claim external validation.
