Session 0041 — 2026-04-16

Opening

  • Start time: 2026-04-16 23:48:49 BST
  • Repository age: 19 days (from 2026-03-28)
  • Sessions completed: 39 (SESSION-0001 through SESSION-0040; SESSION-0037 did not run)
  • Total development time: approximately 48h 56m 0s (approximate historical ~9h 36m through
    session 0007 + precise tracked ~39h 20m 0s from session 0008 through session 0040;
    SESSION-0032 duration unknown, excluded from precise total)
  • LAUNCH-1: CLOSED — GO decision (SESSION-0021, 2026-04-15). Protective disciplines active.
  • Starting state:
    • Highest SPEC-N: SPEC-105
    • Highest SCHEMA-N: SCHEMA-7
    • Highest VAL-N: VAL-5
    • Highest DOC-N: DOC-11
    • Highest RELEASE-N: RELEASE-10
    • Open items: 16 SPEC + 1 SCHEMA + 1 VAL + 4 DOC + 5 RELEASE = 27 total
    • Closed items: 111
    • Completion: 111/138 = ~80.4%
    • v1.0 blockers: none
  • Cleanliness check: PASS
    • Git check: PASS — HEAD (ca62fb6) is the most recent commit touching
      CURRENT_SESSION_STATE.md (0-commit gap)
    • Session-file check: PASS — SESSION-0040 closing section fully populated
  • Carry-forward notes from SESSION-0040:
    • Batch C (SPEC-102/103/104) is the highest-priority remaining batch and
      the largest; requires Opus 1M for the FlatBuffers namespace
      cross-referencing. Design complete in docs/design/ledger_architecture.md.
      Do not start on Sonnet.
    • SPEC-97 LTFS label (9-char normative format) still not implemented —
      carry-forward from SESSION-0039.
    • DEVELOPER_PLAN.md still needs archive ledger / three-tier file hierarchy
      update (carry-forward from SESSION-0033).
    • SPEC-94 dependency for Batch G (SPEC-96) is now satisfied.
  • Planned work unit: open at start; firmed up to (a) discussion-driven filings
    surfacing from ledger architecture conversation and (b) naming/discovery
    mini-batch closing SPEC-106 + SPEC-108.
  • User's opening request: SESSION_START

Work

  • Cleanliness check: PASS (git and session-file checks clean).
  • Discussion thread on Provr.Ledger architecture, scope-vs-ledger separation,
    destination-drive organisation, partial offload semantics, and signing-key
    trust model. Four new SPEC items surfaced and were filed during the
    conversation:
    • SPEC-106: Production-folder discovery for nested destination-drive
      layouts (recursive **/PROVR-*/ glob; producer-organised category
      subfolders permitted; aggregate file at production root).
    • SPEC-107: Failed-offload artifact handling on successful retry
      (ledger-only authority + filesystem cleanup recommended; failed/
      subfolder distinct from corrupted/).
    • SPEC-108: Scope-manifest filename grammar
      (YYYYMMDD_{class}_{card-id}.provr recommended; class vocabulary CAM,
      SND, VFX, MOC, STL, GFX, MIX, OTH).
    • SPEC-109: Trust framework — approved-signer list format, fetch
      endpoint, verifier consumption rules, two-key recommendation. Detailed
      Registry product workflow tracked externally; in-repo entry
      spec-format-only per cross-repo content scope rule.
  • TRACKING.md backfill: SPEC-101 through SPEC-105 written as full entries
    (the items were filed as one-line summaries in CURRENT_SESSION_STATE.md
    during SESSION-0036 but had never been transcribed to TRACKING.md;
    five-item backlog cleared during this session).
  • PROVR_RULES.md amendments:
    • Rev 17: TRACKING.md path corrections — the file lives at
      ~/hijackr/Notes/provr/TRACKING.md (outside the repo), not at
      docs/TRACKING.md inside the repo. Seven path-qualified references
      updated.
    • Rev 18: Cross-repo content scope — the provr repo is the spec and
      format repo only; Registry product workflow, CLI implementation, and
      core internals belong in their respective companion repos
      (provr-registry, provr-cli, provr-core), not in provr. New section added
      to "Repository cleanliness" with forbidden/allowed lists, the test
      question, and per-repo Notes folder layout.
  • Naming/discovery mini-batch — SPEC-106 + SPEC-108 closed:
    • §14.3 amended with the recommended scope-name grammar
      YYYYMMDD_{class}_{card-id}, class vocabulary table, normative force
      (SHOULD), tolerance for non-conforming basenames, and supersession
      deferral to SPEC-88. Underscore added to permitted basename character
      set with structural-separator-only constraint.
    • §14.6 amended with producer-organised category subfolders
      (normative-permitted, unconstrained vocabulary), recursive
      **/PROVR-*/ glob discovery contract, production aggregate file
      location pinned to production folder root, and a worked example.
    • §14.9 character set extended to [A-Z0-9_\-\.] with normative
      restriction on underscore use.
    • docs/design/naming_conventions.md updated with §5.1 (recommended
      scope-name grammar) and §7.1 (producer-organised category subfolders)
      to mirror the spec amendments.
    • ROADMAP.md updated with SPEC-106 and SPEC-108 entries marked
      complete.
  • Commits:
    • a548505 fix(spec): §14 scope-name grammar and production-folder
      discovery — close SPEC-106, SPEC-108
    • 35cbac8 chore(docs): record closures SPEC-106, SPEC-108
  • Companion-repo housekeeping (out-of-session-scope but adjacent): user
    identified that provr-registry repo should be renamed to registr
    (brand consistency with provr/offloadr/hijackr pattern) with new
    description "Registr — Trust and identity for the provr ecosystem.";
    rename + description update performed by the user via GitHub web UI
    (gh CLI not authenticated in session environment).
  • Findings noted, not fixed (carry-forward):
    • PROVR_RULES.md still references ~/hijackr/provr/core/PROJECT_SPEC.md
      and ~/hijackr/Notes/provr/CORE_ENGINEERING.md as authoritative external
      documents, but PROJECT_SPEC.md doesn't exist at that path (or anywhere
      on disk). With rev-18 carving provr-core out as its own repo, the
      "Authoritative source documents" section of the rules file likely needs
      a structural rewrite — the in-repo core/PROJECT_SPEC.md reference is
      stale and the document's content (if it survives) belongs in the
      provr-core repo. Out of scope for this session per the staleness
      protocol; flagged for future cleanup.
    • SPEC-101 through SPEC-105 are not in ROADMAP.md (only the SPEC-106 and
      SPEC-108 closures landed in ROADMAP this session). Pre-existing gap;
      out of scope for this session.

Closing

  • End time: 2026-04-17 02:17:21 BST
  • Duration: 2h 28m 32s (23:48:49 → 02:17:21 BST)
  • Ending state:
    • Highest SPEC-N: SPEC-109
    • Highest SCHEMA-N: SCHEMA-7
    • Highest VAL-N: VAL-5
    • Highest DOC-N: DOC-11
    • Highest RELEASE-N: RELEASE-10
    • Open items: 14 SPEC + 1 SCHEMA + 1 VAL + 4 DOC + 5 RELEASE = 25 total
    • Closed items: 117 (+2)
    • Completion: 117/142 = ~82.4%
    • v1.0 blockers: none
  • Work completed: four new SPEC items filed (SPEC-106 production-folder
    discovery, SPEC-107 failed-offload artifact, SPEC-108 scope-manifest
    filename grammar, SPEC-109 trust framework); two of the four immediately
    closed via §14 spec amendment (SPEC-106, SPEC-108); SPEC-101–105 backfilled
    in TRACKING.md from a five-item documentation backlog; PROVR_RULES.md
    amended at rev 17 (TRACKING.md path corrections) and rev 18 (cross-repo
    content scope rule); §14.3, §14.6, §14.9 spec text and naming_conventions
    design doc updated; ROADMAP closures recorded.
  • Next work unit: Batch C — SPEC-102 + SPEC-103 + SPEC-104 + SPEC-92 close.
    Provr.Ledger FlatBuffers namespace and supporting normative sections.
    Heaviest remaining batch; requires Opus 1M for the cross-referencing. Do
    not start on Sonnet. Design complete in docs/design/ledger_architecture.md.
  • Notes for next session:
    • Batch C (SPEC-102/103/104) remains the highest-priority remaining batch
      and the largest; carry-forward unchanged from SESSION-0040.
    • SPEC-107 (failed-offload artifact handling) depends on SPEC-102 and is a
      natural follow-on to Batch C — schedule directly after.
    • SPEC-109 (trust framework) depends on SPEC-96 (Batch G); spec-side
      work, but Registry-side product workflow tracked separately in
      ~/hijackr/Notes/provr-registry/ per the cross-repo content scope rule.
    • SPEC-97 LTFS label (9-char normative format) still not implemented —
      carry-forward from SESSION-0039.
    • DEVELOPER_PLAN.md still needs archive ledger / three-tier hierarchy
      update — carry-forward from SESSION-0033.
    • PROVR_RULES.md "Authoritative source documents" section needs a
      structural review: PROJECT_SPEC.md path is stale, provr-core has been
      carved out to its own repo, and the rule should reflect the actual
      location of the core engineering documentation (likely now in
      ~/hijackr/provr-core/ or ~/hijackr/Notes/provr-core/). Pre-existing
      finding flagged this session but out of scope for wrap-up.
    • SPEC-101 through SPEC-105 are not in ROADMAP.md (a backlog from
      earlier sessions). Small ROADMAP cleanup pass would close this.
    • Companion-repo rename: provr-registry → registr performed during
      this session; any provr-side documentation that referenced
      provr-registry by name should be checked. Cross-repo coordination
      items live in per-repo Notes folders per the rev-18 rule.
