The BRN-001 acceptance test — *"one PAGENET session +end-to-end on gps3, clearing the station/MAXPAR/panel problems automatically, +not by hand"* — is **not** satisfied by this comparison, and still needs the +PAGENET data. + +Say so in as many words. Otherwise someone later reads a green LUZON comparison +as pipeline acceptance, which is precisely the "check that reports success +without having inspected the thing" pattern your own §15.5 catalogues. + +--- + +## 2. Your #1 unverified risk has a cheap mitigation — request it now + +You flagged, correctly: *whether 5.4 reads a 5.2 campaign's `OBS/` directly.* +And you noted that if it does not, the fallback is re-converting from RINEX — +which exists **only for the days with no reference solution**. + +That is a dead end, not a fallback. Worth naming as such in the runbook. + +**The mitigation is a small, specific follow-up request to Abegail:** the RINEX +for the ten days that *do* have solutions — **2025 DOY 029–033** and **2026 DOY +106–110**. Roughly 10 days × ~25 stations: tens of megabytes, not another 22 GB. + +**Ask before you need it.** The request has human latency; the test does not. +Raise it with Alfie as a message to send today rather than discovering the need +mid-run and waiting on a reply. + +--- + +## 3. Pick one block. Do not mix them. + +The ten usable days are **two disjoint blocks a year apart**: 2025 DOY 029–033 +and 2026 DOY 106–110. Between them sit different IGS product vintages, possibly +different station sets, and possibly different receiver or antenna +configurations at the same sites. Comparing across them adds a confounder for no +benefit. + +**Use one block, and record which and why.** If only one is practical, prefer +**2026 DOY 106–110** — it is closer in epoch to the PAGENET data, so a later +cross-network comparison is less contaminated. + +This sharpens the model discipline rather than relaxing it. **Five days is not +much signal.** With that few, an I14→I20 model shift and a genuine tuning effect +are *harder* to separate, not easier. "Reproduce her numbers under I14 first, +then vary one thing" matters more here than it would over thirty days. + +--- + +## 4. The missing scripts — resolve by classification, do not re-derive + +Your breakdown is the right shape: 2 not needed for a daily comparison +(`ADD_WK`, `ADD_MON`), 4 `H`-suffixed variants that may have non-`H` +equivalents, 2 that should be unnecessary when running from staged products. + +Two rules on top of it: + +1. **Do not write replacements for missing scripts.** Same reasoning that + applied to `PAGENET_DLY.PCF`: a re-derived component means the run exercises + something nobody has ever validated, and a green result then proves nothing. +2. **Record the classification in the repo, per script, with its reason.** + "8 missing" in a session log is not actionable in six months. A table naming + each script and its disposition is. + +If the `H`-variants turn out to have **no** non-`H` equivalent, that is a finding +about 5.2 → 5.4 portability in its own right — it belongs in the runbook as a +stated limitation, not as a footnote. + +--- + +## 5. Escalate the irreproducibility finding out of the runbook + +*"Sixteen years of solutions are irreproducible; the raw observations behind all +but ten of those days are on staff machines."* + +That is a **continuity-audit finding**, not a reprocessing detail, and §7 of a +runbook is the wrong place for it to live. It belongs alongside the other five +in `RESUME_NEXT.md`'s audit, ranked. + +By that audit's own logic it ranks high: it is not loss of data, it is loss of +the **ability to regenerate** data — the same category as *"losing the knowledge +of how to use the data"* that the audit puts at #1, and strictly worse than the +hardware concerns it puts at #5. + +It also has a concrete, cheap first action, which is what makes it worth +escalating rather than merely noting. **Those observations can be copied and +checksummed now**, from machines that are currently accessible, by people who +currently work there. They cannot be regenerated later. That is exactly the +shape of the Tier 1 station-metadata item: the window is **staff tenure**, not +hardware life. + +--- + +## 6. Put the PCF parsing trap in code, not only in the log + +Three tables, different column meanings, column 3 an OPT directory in one and a +parameter value (`$201`) in another — that produced twelve invented directories +on the first pass. + +The orchestrator parses these files. **Put the column layout in a comment at the +parse site, and add a test fixture containing all three table types**, so the +next parser cannot make the same read. A trap recorded only in a session log +gets rediscovered; a trap recorded in a failing test does not. + +This is the same remedy that worked for the SIGPIPE and `lsof +D` bugs — the fix +was pinned in the script by a comment carrying the literal evidence. + +--- + +## 7.

The `F1_` filenames were right. Neither was ever placed next to the +other, and the conclusion drawn across them was wrong. + +So the family is slightly wider than "unverified claims".

The constraint is peak + concurrent footprint during a run, not annual growth. At 270 stations a single + day's campaign is ~1.6 GB, so a week in flight is ~11 GB. Comfortable. + +3. **Retained solutions barely scale at all.** + 6.85 MB/day for a 25-station network. Solution size tracks parameter count, + so ~10.8× for 270 stations → **~74 MB/day ≈ 27 GB/year.** + +**The ratio that matters: ~651 GB/year of raw observations against ~27 GB/year +of retained results — roughly 24 : 1.** So the retention policy question is +almost entirely *"what do we keep of the raw data, and in what format"*, and +barely at all *"what do we keep of the outputs."* Keeping every solution forever +is cheap. Keeping every observation uncompressed is not. + +4. **IGS products are a fixed cost.** 9.1 G here, independent of how many + stations you process — it scales with time span and product type only.

It refuses to write if any row lacks +`CPU=`, so the format mistake cannot recur silently. + +### 4b.2 §1.1c was wrong: `FTP_DWLD` does gate the run + +§1.1c said every product was local so `FTP_DWLD` could be dropped. The products +are local **in 5.2-era legacy naming** (`igs22364.sp3.Z`); 5.4 reads long-name +(`IGS0OPSFIN_20251210000_01D_15M_ORB.SP3.gz`).

Everything before it +worked — `LUZON.BLQ/.ATL/.CLU` copied into the campaign, `ANTENNA_I14.PCV` +confirmed in use, orbit copied to `.PRE`, ERP to `.IEP`. + +``` +File .../DATAPOOL/BSW54/IAR23644.OSB cannot be provided (mandatory) +*** copyRef: 1 mandatory file is missing +``` + +`R2S_COP` *generates* `IAR_*.OSB` by running `BIA2OSB` over a bias-SINEX input: + +```perl +putKey(...

Two frames in one directory is the + configuration most likely to fail quietly rather than loudly. +4. **Do the RINEX 3 fiducials stage cleanly** via `V_RX3DIR`?
